The invention further relates to a method for producing such a balcony.

A balcony is a platform on a building that is above the ground level and protrudes from the building. It is usually edged by a parapet or railing.

The spread of balconies has increased in the recent past. In the 18th and 19th centuries, only a few buildings had balconies. Among other things, this was due to the strongly developing industry and the resulting odor nuisance. Therefore, buildings were more likely to be in rural areas or urban areas with little industry and balconies.

Furthermore, there was often no need for a balcony on the part of the residents. The workload was very high, so that many residents had no free time to spend on a balcony. Balconies were thus usually people who were not exposed to this high workload. This was only a very small part of the population.

Furthermore, after the destruction of the Second World War, the focus was on accommodating the many people looking for housing. A balcony was considered a luxury. Therefore, residential buildings were built rather without balconies.

In addition, balconies regularly increase the requirements for the statics of a building, which entails increased costs and additional costs.

• Eine nachträgliche Ausstattung mit einem Balkon bedeutet einen Eingriff in die Statik des bestehenden Gebäudes.
• Ein nachgerüsteter Balkon greift stark in das Erscheinungsbild eines bestehenden Gebäudes ein.
• Insbesondere bei älteren Gebäuden sind gegebenenfalls Denkmalschutzauflagen zu beachten.

The air has improved significantly in urban areas over the past decades. Furthermore, the company is on average exposed to a lower workload. Also the leisure time behavior has changed. All this has increased the demand for balconies. If balconies are to be retrofitted to an existing building, the following must be considered:

• Subsequent equipment with a balcony means an interference with the statics of the existing building.
• A retrofitted balcony strongly intervenes in the appearance of an existing building.
• In particular, in older buildings, if necessary, listed building regulations must be observed.

In German utility model DE29920081U1 a balcony is described in which the balcony floor structure is constructed of a plurality along a common extension direction extended cassette elements. Each cassette element is shaped in cross-section perpendicular to the extension direction in such a way that it has a base which forms part of the balcony floor underside and that starting from the base at least one coupling leg with a coupling region spaced from the base for connecting adjacent cassette elements and / or to the support a Balkonbodenbelags extends to the balcony floor structure. Each coupling region has a form-fitting section which extends along the direction of extension and via which adjacent cassette elements are connected to one another in a form-fitting manner.

A disadvantage of this solution is that the positive connection portion of the cassette elements is designed such that to ensure a sufficiently stable statics of the balcony floor structure, the cassette elements must have a high degree of rigidity and resilience in itself. This requires certain material thicknesses of the cassette elements, which in turn has a correspondingly high weight result. The higher weight is associated with a greater effort during transport and installation.

It is an object of the invention to provide a balcony that is much lighter and easier to install and easier to install compared to current solutions in terms of its weight. As a result, especially the balcony assembly can be done faster and more efficient and the total cost of the balcony can be further reduced.

The object is achieved by a balcony having the features of claim 1 and by a method for producing such a balcony having the features of claim 11.

According to the invention, it is provided that the cassette elements, the carrier profile or both are formed from bent thin sheet and that in each case between the base and coupling leg of the cassette elements a coupling leg angle A of 60 to 70 degrees is formed.

A thin sheet is made of a metal or a metal alloy, preferably of galvanized steel. The thickness of the thin sheet is preferably up to 3 millimeters, more preferably up to 2.5 millimeters, and most preferably 1 to 2 millimeters. Such a thin sheet can be easily processed by means of a forming tool, in particular a Abkantwerkzeugs.

By using thin sheet metal significantly less material, so metal or metal alloy is needed. This reduces the material costs of the balcony. The cassette elements formed from thin sheet significantly lighter than flat steel with material thicknesses well over 5 mm and formed of thin sheet by folding cassette elements are significantly cheaper than extruded aluminum profiles. As a result, these cassette elements are cheaper and easier to transport and assemble. Regularly, therefore, transport and installation of the entire balcony can be done by a single person without special lifting tools.

In comparison to the currently widely used welded support profiles made of flat steel with metal thicknesses of more than eight millimeters, the use of thin sheet is also very advantageous for the formation of the carrier profile. As a result, it is usually possible to dispense with a lifting crane for moving carrier profiles / carrier profile frames. This further reduces the cost of transport and assembly and thus the overall costs.

A uniform along the direction of extension of the coupling leg of the cassette element is inevitably achieved when the cassette element is made by folding a metal thin plate. By the manufacturing step of the Abkantens s the direction of extension of the cassette element is inevitably predetermined by the edge of the Abkantwerkzeugs.

The term "chamfering" used in the context of this invention is a bending process known from the forming technique. Preferably, the term folding is used below.

Bending is a well-known and established forming process usually for sufficiently thin sheets of metal or metal alloys. This process is easy to control and opens up a great variety of possible coupling legs. The folding can be done mostly at high speed. Depending on the precision of the forming tool, the processing results can be reliably reproduced down to the millimeter range. As a result, this forming technique is very well suited for the efficient production of cassette elements with coupling legs of this type.

The aforementioned method enables a wide variety of geometries of the cassette elements. This in turn makes, for example, a prefabrication of balcony components in high quantities possible. This reduces both the production costs and the installation time for a balcony.

Of two opposite balcony floor pads, which are structurally formed in opposite carrier profile frame sections, preferably extends an integrally formed cassette element along the extension direction already mentioned.

The base of a cassette element has a width of preferably 10 to 100 centimeters, more preferably 15 to 70 centimeters and most preferably 20 to 30 centimeters perpendicular to the direction of extension, especially when using thin sheet. The wider the base of a cassette element is formed, the more it tends to bulge-like deformations. Therefore, the design of the cassette elements depends on the expected intrinsic and traffic loads.

Each cassette element has at least one coupling leg. This is preferably arranged in the edge region of the base. However, there may also be a plurality of coupling legs per cassette element, in particular two, which extend at both edge regions of the base of the cassette element along the extension direction.

Further, a cassette member may include a coupling leg and another leg extending away from the base which does not perform a function of coupling adjacent cassette members. This further limb may be formed as an initial limb or as a limb which extends at a defined angle, for example substantially perpendicular, or curved at a varying angle away from the base of the cartridge elements. The further leg forms both a structural reinforcement for supporting the cassette element on the balcony floor support of the carrier profile frame and a lateral boundary of the base, to give this a tub function for guiding water, which passes from above to the cassette elements.

Each coupling leg has a coupling region with a positive connection section for coupling adjacent cassette elements. Two such adjacent cassette elements are mechanically coupled to one another by means of the form-fitting sections of their coupling regions extending parallel along the extension direction. The form-fitting sections are designed such that a displacement of adjacent cassette elements is blocked transversely to the extension direction. In order to prevent a relative displacement of adjacent cassette elements along the extension direction, the use of less fixing means which block such a displacement is sufficient. This also reduces the installation effort.

For balconies, there is often the problem of how the water falling from above (eg rainwater) can be slid off without dripping onto an underlying balcony. In the solution according to the invention forms the balcony floor bottom, formed from a plurality of coupled together via their form-fitting sections cassette elements part of the drainage system of the balcony. Thus, the balcony base structure formed from the cassette elements simultaneously fulfills the function of drainage in addition to the static requirements. The water that hits the balcony floor top, comes towards the base of each cartridge element, which forms a drainage pan together with the legs extending away from the base, in particular the coupling legs, and can be there from, for example, by a deliberately provided during assembly minimal Guiding gradient in the direction of a carrier profile of the carrier profile frame.

Preferably, the carrier profiles, in which passes the guided from the cassette elements water, structurally designed such that they have a water drainage section. Of the water drainage sections or sections of the carrier profile frame, the water can be introduced by means of a dewatering device, for example in the form of pipes or gutters in a usually existing building drainage system. However, the water can also be passed from here into a collecting container, for example from the carrier profile frame or from the base of a cassette element. In current solutions, the flooring is often out of balance to cause drainage of rainwater in a direction predetermined by the slope. As a result, however, a balcony user is not quite in balance, which can be detrimental in some situations. Furthermore, these dewatering solutions often provide additional dewatering devices, such as complex containment and piping systems. In conventional balconies known from the prior art, those structural elements which function as a balcony floor structure are provided in addition to a drainage system. When balcony according to the invention the balcony floor is in Libra. This balcony realizes an integration of the static structural function for the balcony floor with the drainage function of the impinging on the balcony floor water. Conventional systems require one, among other things additional material and assembly costs. This increases both the cost and the assembly time.

The balcony floor underside can form a balcony ceiling completely or partially. The balcony ceiling is the visible, uncovered part of the balcony floor bottom, which a viewer sees when he looks from below at the balcony above. The cassette elements, which by means of their respective bases can form a large part of the balcony floor underside, can be designed in different colors or in a uniform manner. This allows a balcony ceiling to be designed freely in terms of its appearance. For example, if the balcony ceiling is white, the resulting balcony receives more light thanks to the increased light reflection. The dimensioning of the cassette elements, in particular transversely to their extension direction, contributes to the visually structured appearance of the balcony ceiling. This can be dispensed with further measures, such as an additional cover provided for the design of the balcony ceiling. This can save time and costs for designing the balcony ceiling.

• Die Lasten können durch ein Tragwerk mit Kragträgern aufgenommen werden. Ein Kragträger ist ein einseitig gelagerter, waagerechter Balken, an dem eine Last hängt. Er ist Teil eines Gebäudes. Als Balken ausgebildet, ist seine Länge in der Regel deutlich größer als seine Höhe und Breite. Ein Kragbalken wird in der Regel auf Schub, Biegung und mitunter auf Torsion beansprucht. Bei dieser Lösung können zwischen den Kragbalken oder Trägerprofilrahmen übereinander angeordneter Balkone zusätzlich verlaufende Züge, vorzugsweise aus Metall, vorgesehen sein, die entweder mit der Gebäudewand verbunden sind oder eine Verbindung zwischen zwei Balkonen herstellen und jeweils einen Teil der Lasten aufnehmen bzw. ableiten.
• Die Aufnahme der Lasten kann ferner mittels eines Ständerwerks mit zwei senkrechten Ständern erfolgen. Bei einem derartigen Ständerwerk ist der Balkon einerseits mittels des Haltesystems mit der Gebäudewand verbunden und andererseits an zwei senkrechten, deutlich von der Gebäudewand beabstandeten Ständern fixiert. Die Last wird teilweise durch die zwei senkrechten Ständer aufgenommen.

• Des Weiteren kann die Lastaufnahme auch mittels eines Ständerwerks mit vier senkrechten Ständern erfolgen. Hierbei wird der Balkon an diesen vier Ständern fixiert. Davon haben zwei Ständer einen geringen und die verbleibenden zwei Ständer einen im Vergleich dazu größeren Abstand von der Gebäudewand. Die Last wird durch die vier senkrechten Ständer aufgenommen.

The recording of the loads occurring on a balcony can be solved differently:

• The loads can be absorbed by a structure with cantilevers. A cantilever beam is a one-sided, horizontal beam to which a load hangs. He is part of a building. Formed as a beam, its length is usually much larger than its height and width. A cantilever is usually stressed on thrust, bending and sometimes on torsion. In this solution, additionally extending trains, preferably made of metal, can be provided between the cantilever or girder frame superimposed balconies, which are either connected to the building wall or establish a connection between two balconies and each receive or deduce a portion of the loads.
• The inclusion of the loads can also be done by means of a framework with two vertical uprights. In such a framework the balcony is connected on the one hand by means of the holding system with the building wall and on the other hand fixed to two vertical, clearly spaced from the building wall uprights. The load is partially absorbed by the two vertical uprights.

• Furthermore, the load bearing can also be done by means of a stator with four vertical uprights. Here, the balcony is fixed to these four stands. Of these, two stands have a small and the remaining two stands a greater distance from the building wall in comparison. The load is absorbed by the four vertical uprights.

• beim Eingreifschenkel der Formschlussabschnitt auf der Oberseite des Koppelbereiches,

ausgebildet ist.Each of the above-described embodiments is advantageously characterized in that the coupling leg is designed either as an overlapping leg or as an engagement leg, wherein viewed from the base of the cassette element forth in the direction of the coupling legs

• at Übergreifschenkel the positive connection portion on the underside of the coupling region,
• the engagement leg on the upper side of the coupling region,

is trained.

The coupling leg can be configured as an overlapping leg or as an engagement leg. Each version of the coupling leg has a positive connection section. Viewed from the base of the cassette element, the form-fitting section is arranged on the upper side of the engaging leg and on the underside of the engaging leg. If an overlapping leg and an engagement leg are coupled together to connect two cassette elements, the overlapping leg engages over the engagement leg. As a result, the form-fitting sections touch on the underside of the overlapping leg and the upper side of the engaging leg. If a weight force acts on the overlapping leg from the base of the cassette element from above, the positive connection between the overlapping leg and the engaging leg is loaded by the weight force. On The balcony objects and / or persons generate such weight.

By this type of mechanical coupling and by this arrangement of the form-fitting section on the overlapping leg and the engaging leg of adjacent cassette elements a Balkonbodentragwerk is formed, which carries recorded on a usually disposed thereon balcony floor covering loads.

The embodiment described above is advantageously characterized in that a plurality of cassette elements each have at both ends of the base a coupling leg, wherein the one coupling leg is formed as Übergreifschenkel and the other coupling leg as Eingreifschenkel, and the positive connection to the form-fitting portions of adjacent cassette elements through the Coupling of the Übergreifschenkels a first cassette element with the engagement leg of a second cassette element is made.

In the majority of cassette elements, an overlapping leg and an engaging leg are present per cassette element. As a result, several adjacent cassette elements can be positively connected with each other. This is preferably used to form a coherent balcony floor structure of significantly more than two cassette elements. Due to this connectability of the cassette elements, the individual cassette elements can be relatively small compared to the total area of the balcony floor construction. This facilitates the transport of the balcony components and the installation of the balcony.

The embodiments with a cassette element having an overlapping leg are advantageously characterized in that a parallel to the base of the cassette element extending portion of the Übergreifschenkels forms with its top a floor covering support for a balcony floor covering. The size of the bearing surface of this Floor covering of the cassette element is determined at a given height of the cassette element, inter alia, by the coupling leg angle. Depending on the material thickness of the cassette elements and the material used for the balcony floor covering and the resulting weight of the balcony floor covering, the width of the floor covering support of the cassette element and the spacing thereof is selected from the base.

The floor covering of the cassette element can be covered with a balcony floor covering, for example made of wood, plastic, concrete, stone, other materials or a combination thereof. These materials can be screwed, for example, with the floor covering of the cassette element. This connection and / or the weight of the balcony floor covering exerts an additional holding force on the positive connection of the form-fitting sections.

However, it is not absolutely necessary to place an additional balcony floor covering on the floor covering of the cassette element. For example, the cassette elements could be folded out of thin sheet metal so that the floor covering support of the cassette element, viewed in a direction perpendicular to the direction of extension, extends continuously parallel to the base. As a result, the top of the cassette elements forms the balcony floor top.

All of the preceding embodiments are preferably characterized in that adjacent cassette elements are fastened together in their common form-fitting sections with fixing means. For this purpose are suitable as fixing agents: adhesive, screws, nails, rivets soldering, welding, other fixers not mentioned here or combinations thereof. Preferably, the adjacent cassette elements are riveted together. For this purpose, after the positioning of the cassette elements at defined locations in their form-fitting sections, first a drilling of the holes, followed by the riveting of these holes. The Fixing adjacent cassette elements together fixes the previously established positions of adjacent cassette elements and prevents their displacement along or transversely to the extension direction of the cassette elements. Furthermore, the cassette elements fixed to one another preferably form the balcony base structure, which is preferably made only of thin sheet metal, which, in spite of the low material thickness, provides the load capacity required for building balconies despite the riveted, partially form-fitting sheet metal connection. If all adjacent cassette elements are connected to one another by means of fixing means, then individual cassette elements can neither be removed nor displaced. A balcony floor construction formed with such a balcony floor structure is stable and very light. Unlike some fixers, using rivets has the advantage that rivets can be drilled out. As a result, once fixed together cassette elements can be subsequently dismantled, if required, for example, for a repair replacement of a single cassette element.

In a cassette element with a plurality of coupling legs, the coupling leg angle can be formed differently large. Preferably, however, the embodiment described above with the coupling leg angle is characterized in that the coupling leg angle of each cassette element are the same size.

If the coupling leg angles of each cassette element are the same size, the static properties of the balcony floor structure formed by the cassette elements are uniform transversely to the direction of extent. This makes the stability of the balcony floor construction as a whole calculable.

The abovementioned embodiments of the invention are advantageously characterized in that the form-fitting section of each coupling leg has a first form-fitting section extending parallel to the base of the cassette element. This first form-fitting section is through the spaced in the coupling leg angle away from the base coupling leg of the base and oriented parallel to the base.

This has the following advantage with a positive connection of two adjacent cassette elements. Viewed from the base of the cassette element, in the case of a coupling leg designed as an engaging leg, the first positive-locking section is directed upwards, that is to say away from the base and oriented parallel to the base. The first form-fitting section of a coupling leg which is formed as an overlapping leg and which is opposite this first form-fitting section of the engaging leg, in turn, is oriented downwards, that is to say towards the base, and likewise aligned parallel to the base. The back of the leg Übergreifschenk is also oriented parallel to the base with the coupling leg material thickness and has viewed from the base upwards. This section at least partially forms a fixing agent section. This Fixiermittelabschnitt is accessible from above. As a result, adjacent cassette elements can very easily be fastened to one another from above by means of fixing means, after they have been connected to one another by means of the form-fitting sections of adjacent overlapping legs and engaging legs. This fastening is preferably carried out by means of rivets. But there are also other fixatives used, such as screws. One such use of the fixing means has the advantage, inter alia, that each cassette element can still be displaced along the extension direction before the fastening of adjacent cassette elements. A cassette element is only fastened to the adjacent cassette element when it has reached its intended position. This facilitates the step-by-step installation of the balcony floor structure.

The preceding embodiment is advantageously characterized in that, following the first positive-locking section, a second positive-locking section is formed, which extends angled or curved away from the first positive-locking section.

The engagement leg of a cassette element hooks under the overlapping leg of another adjacent cassette element and the combination of the first mold closure section and the second form-fitting section forms an edge or a curve. As a result, this edge or curvature acts in the form-fitting section as a mechanical stop which limits the movement of adjacent cassette elements transversely to the extension direction. This mechanical stop facilitates the step-by-step assembly of adjacent cassette elements by first applying the overlapping leg with its second positive-locking section at an acute angle to the second positive-locking section of the engaging leg. Subsequently, this acute angle is reduced by a rotation of the cassette element with the overlapping leg about a rotation axis parallel to the extension direction to zero and thereby produces the positive connection of the form-fitting portions of the adjacent cassette elements.

The second form-fitting section preferably extends at right angles away from the first form-fitting section. This represents a particularly easy to produce by bending of thin sheet variant of the angled form-fitting portion.

The preceding embodiments are advantageously characterized in that the carrier profile frame encloses the balcony floor construction and the cassette elements extend integrally along their extension direction between opposite sections of the carrier profile frame. Since the cassette elements extend integrally along their direction of extension between opposite portions of the carrier profile frame, no further support elements for the cassette elements along their extension direction are required. This reduces the effort for balcony installation. Furthermore, the integrally extending cassette elements also serve as an aesthetic design element for the balcony design. This allows elaborate subsequent design measures of the balcony, for example in the form of Disguises are dispensed with. This reduces the time, material and cost of the balcony design.

The enclosing of the balcony floor construction by the carrier profile frame also has the consequence that from the top of the balcony incident rainwater transported in the direction of the carrier profile frame and can be derived from there, for example by means of a conduit system. This line system is preferably formed from water drainage sections, which is designed as a structural component of the carrier profile frame forming carrier profiles. In this way, it is not necessary to provide components that are used solely for drainage of the balcony floor construction of the balcony. The balcony floor structure integrates so to say by its design, the drainage functionality at the same time to its static function.

The object underlying the invention is further achieved by a method for producing a balcony. The method comprises the following method steps:

• Providing a carrier profile frame formed from carrier profiles, which forms a balcony floor support for portions of a balcony floor underside;
• Folding at least two thin sheet metal cassette elements, each cassette element extending along an extension direction predetermined by the folding, and each cassette element being shaped in cross section with respect to the extension direction, having a base forming part of a balcony floor bottom and extending from the base at least one coupling leg with a coupling region spaced from the base for connecting adjacent cassette elements and / or for supporting a balcony floor covering extends, each coupling region has a form-fitting portion for the positive connection of adjacent cassette elements and wherein in each case between the base and coupling legs of the cassette elements a coupling leg angle A from 60 to 70 degrees is formed;
• Inserting a first cassette element onto mutually opposite sections of the balcony floor supports of the carrier profile frame;
• Inserting a second cassette element on opposite sections of the balcony floor pads of the carrier profile frame, wherein the second cassette element is inserted so that the coupling leg of the first cassette element next to the coupling leg of the second cassette element comes to rest such that the positive connection portion of the first cassette element and the form-fitting portion of the second Cassette element enter into a positive connection; and
• Fixing the cassette elements on the carrier profile frame.

As described above, the bending claimed in the context of this invention is a bending process known from the forming technique. Subsequently, only the term of the Abkantens is used.

The support profile frame forming carrier profiles are made of metal, a metal alloy, plastic or a combination of the aforementioned materials. The carrier profile frame is formed by the carrier profiles are assembled into a carrier profile frame and then connected together. This connection is permanent or detachable. Preference is given to a permanent connection of the carrier profiles to a carrier profile frame, for example by welding or soldering. Such carrier profiles are preferably formed as follows. Viewed in cross-section, such a carrier profile is shaped like a polygonal C with an opening. From the upper end of this opening extends an upper end portion, while extending from the lower end of the opening, a lower end portion. These two end portions extend substantially perpendicularly away from the carrier profile and are aligned parallel to each other. The lower end portion forms a balcony floor support of the carrier profile while the upper end portion forms a floor covering support of the support profile for a balcony floor covering, which is provided regularly as part of the balcony floor construction.

The carrier profile frame is fastened by means of a holding system to a building wall. This holding system is designed with or without a vertical stand system. Without a stand system, the load is taken up by means of one or more cantilevers and possibly by additional, connected to the building wall or adjacent balconies trains, preferably made of metal. The design and operation of a cantilever is described above. The use of a stand system may be required for large balconies. In these cases, the stand system provides for a partial or complete absorption of the load capacity of the balcony.

The cassette elements are made of metal in the form of thin sheet metal. For this purpose, a galvanized sheet steel is preferably formed as follows: The thin sheet is folded in a forming tool to form a cassette element. The extension direction of the forming edge of the forming tool thereby defines the extension direction of the cassette element. After folding, the cassette element has the following structure: viewed in cross section to its extension direction, the cassette element has a base. The base is after installation part of a balcony floor bottom. Composite cassette elements form with their respective base the complete balcony floor underside. The balcony floor underside can form a balcony ceiling completely or partially. The balcony ceiling is the visible, uncovered part of the balcony floor bottom, which a viewer sees when he looks from below at the balcony above.

The thin sheet is folded so that extends away from the base at least one coupling leg along the extension direction. Between the base and coupling leg a coupling leg angle is formed. The coupling leg angle is 60 to 70 degrees. The coupling leg has a coupling area. The coupling region is arranged at a defined distance from the base. Preferably, the coupling region is arranged on the end remote from the base of the coupling leg. The coupling region of the coupling leg is in turn by the Abkantvorgang of the sheet preferably formed at least partially parallel to the base. Furthermore, the coupling region has a positive connection section. The form-fitting section preferably has a first and adjacent thereto a second form-fitting section. Here, the first form-fitting portion is formed parallel to the base as part of the coupling region. By one or more further Abkantschritte the second positive locking portion is angled or bent in the direction of the base. The second form-fitting section preferably forms the termination of the coupling region. Such coupling legs are formed as so-called engaging leg or as over-limb. The first and second form-fitting portion of the engaging leg is respectively formed on the top side facing away from the base of the coupling leg. In contrast, the first and second form-fitting section of the overlapping leg are respectively arranged on the base of the underside facing the coupling leg. When viewed in cross-section, the cassette element preferably has a coupling leg formed as an overlapping leg at one end of the base and a coupling leg formed at the other end of the base of an engagement leg. Deviating from individual cassette elements can be provided, which are folded at the edge of the coupled cassette elements only with a trained as engaging leg coupling leg or only with a designed as an overlapping leg coupling leg.

Adjacent cassette elements are connected to each other during assembly of the balcony floor construction by means of their adjacent form-fitting sections. The rear side of the first form-fitting section of the overlapping leg preferably forms a floor covering support of the cassette element and can therefore be used for laying a balcony floor covering which forms the visible balcony floor top side.

When mounting the balcony floor construction, a first folded cassette element of this type is inserted into the carrier profile frame so that it is on opposite sections of the balcony floor support of the Carrier profile frame rests. Preferably, these sections are oriented parallel to each other. However, this depends on the geometry of the balcony.

Subsequently, a second cassette element is placed on the balcony floor support of the carrier profile frame. Thereafter, the first cassette member is preferably connected to the adjacent second cassette member as follows. The engagement leg of a cassette element hooks under the overlapping leg of another adjacent cassette element and the combination of the first mold closure section and the second form-fitting section forms an edge or a curve. As a result, this edge or curvature acts in the form-fitting section as a mechanical stop which limits the movement of adjacent cassette elements transversely to the extension direction. By this mechanical stop the stepwise mounting of adjacent cassette elements is facilitated by the Übergreifschenkel is first applied with its second form-fitting portion at an acute angle to the second form-fitting portion of the engaging leg. Subsequently, this acute angle is reduced by a rotation of the cassette element with the overlapping leg about a rotation axis parallel to the extension direction to zero and thereby produces the positive connection of the form-fitting portions of the adjacent cassette elements.

In this manner, further cassette elements are preferably inserted into the carrier profile frame and connected to one another until the area enclosed by the carrier profile frame is completely filled. In this case, the cassette elements are displaceable along the extension direction up to a certain point, so that they can be threaded into the carrier profile frame.

Subsequently, the form-fitting interconnected cassette elements are fixed to the carrier profile frame and each other. For this fixation screws, rivets, adhesives, other fixatives or a combination thereof are used. Rivets are preferably used for this purpose.

For this purpose, a hole in the positive connection region of the cassette element is made by the thin sheet of both cassette elements after assembly and adjustment of the added cassette element. Immediately following the rivet is placed in this hole and the two cassette elements are riveted together in this way. A corresponding procedure is carried out for fixing the cassette elements on the carrier profile frame. Unlike some fixers, using rivets has the advantage that rivets can be drilled out. As a result, mutually fixed cassette elements can be subsequently dismantled, if necessary.

After the entire balcony floor structure has been constructed from the interconnected cassette elements, a balcony floor covering is placed on the floor covering support of the carrier profile and the floor coverings of the adjacent cassette elements and fixed to the cassette elements. For this purpose, screws, nails or specially trained fixatives are. Preferably, screws are used for this purpose.

An advantage of this method is that many balcony components can be prefabricated, the transport of the balcony components is therefore easy and the final assembly is carried out to a balcony of a few people without special lifting equipment.

The preceding method is preferably further developed in such a way that the carrier profiles forming the carrier profile frame are folded from thin sheet, a carrier profile strand being first folded from thin sheet, then a plurality of carrier profiles are mitred from the carrier profile strand and the plurality of carrier profiles become a carrier profile frame connected.

From the carrier profile strand, the carrier profiles are preferably cut directly by miter cut to the required length or they are first cut to the required length and then the carrier profile mitred.

The thin sheet used for folding consists of a metal or a metal alloy, preferably of steel. The thickness of the thin sheet is preferably up to 3 millimeters, more preferably up to 2.5 millimeters, and most preferably 1 to 2 millimeters.

The use of bevelled thin sheet for carrier profile frames results in a significant weight saving compared to many currently used carrier profile frames of thicker flat steel. The flat steel used regularly has two to three times greater material thickness, so that the components made of it have twice and three times the weight. The significantly lower weight compared to this results in lower costs for transport and assembly and thus lower costs.

The preceding method is advantageously further developed in such a way that the plurality of carrier profiles are connected to the carrier profile frame by means of welding, soldering or other suitable method. Preferably, the so-called MSG welding is used. Under MSG welding is understood in the context of this invention metal welding with inert gases. This is a welding process using inert gas. This shielding gas prevents oxidation of the weld after welding. The shielding gases used are argon, helium or other suitable shielding gases. This welding process is well established and well controlled. The advantage is that in particular the welds of cut galvanized steel sheets do not have to be reworked after welding, for example with mechanical methods and / or rust inhibitors.

FIG. 1 shows a preferred embodiment of a balcony in a schematic not to scale supervision of the balcony. The balcony has a rectangular in plan view carrier frame 10 with two long and two short sides. The carrier profile frame 10 is formed from a first carrier profile 12, a second carrier profile 14, a third carrier profile 16 and a fourth carrier profile 18. The carrier profiles 16 and 18 form the long sides of the carrier profile frame 10 which is rectangular in plan view. The short sides of the rectangular in the plan view carrier frame 10 are formed by the carrier profiles 12 and 14. An extension direction E runs between the carrier profiles 16 and 18. The extension direction E is parallel to the carrier profiles 12 and 14. The carrier profile frame 10 is connected to four vertical uprights 20. The four stands 20 are arranged at the four corners of the rectangle and serve to accommodate the loads taken from the balcony. Further, the carrier profile frame 10 is connected by means of a holding system, not shown in this figure with a building wall 30. Of the Carrier profile frame 10 encloses a balcony floor structure 42. The balcony floor structure 42 has a plurality of interconnected cassette elements 50. Each cassette element 50 has a rectangular base with two long sides and two short sides. Along the long sides of a cassette element 50 extend one to two connecting sections not shown here, in which adjacent cassette elements partially overlap. These connection sections contain support sections and form-fitting sections. Each cassette element 50 extends integrally with the long sides along the extension direction E between the two carrier profiles 16 and 18. The long sides of the cassette elements 50 are thereby parallel to the short carrier profiles 12 and 14. The individual cassette elements 50 are positively connected to each other by means of form-fitting sections. These support sections and form-fitting sections are described in detail in the further figures. The plurality of cassette members 50 are composed of an initial cassette member 52, a plurality of center cassette members 54 and a terminal cassette member 56. The structure of the carrier profile frame 10 and a cassette member 50 is shown in the other figures.

FIG. 2 shows a cross-sectional view taken along the dotted line II-II FIG. 1 , The parts of the carrier profile frame 10 shown here include the first carrier profile 12 and the second carrier profile 14 opposite thereto. In the present cross-sectional view, each of the aforementioned carrier profiles is substantially shaped like a rectangular C with two long vertical sides, two short horizontal sides and one opening for receiving cassette elements 50. This opening is located on one of these two long sides and is arranged above the center of the carrier profile. From the upper end of this opening extends a horizontal upper end portion, and from the lower end of the opening extends a horizontal lower end portion. These two end portions extend substantially perpendicularly away from the carrier profile and are aligned parallel to each other. The lower end portion forms a Balcony floor support 44 while the upper end portion forms a floor covering support 461 of the carrier profile frame. The balcony floor covering 42 together with a balcony floor covering 46 a balcony floor construction 40. The balcony floor covering 46 usually consists of wood planks or flagstones, which are placed on the floor covering 461 of the support profile and / or the floor covering 462 of the cassette element. The wooden planks or stone slabs regularly extend in one piece along the extension direction E and can be fixed by means of screws (not illustrated here) to the floor covering support 461 of the support profile and / or the floor covering support 462 of the cassette element.

The balcony floor construction 40 has a balcony floor top 401 and a balcony floor bottom 402. The balcony floor top 401 is formed from the top of the balcony floor covering 46 while the bottom of the balcony floor structure 42 forms the balcony floor bottom 402. The balcony floor bottom 402 is partially on the balcony floor support 44 of the surrounding carrier profiles. The balcony floor structure 42 is formed from a plurality of parallel adjacent cassette elements 50. For this purpose, during the assembly process, an initial cassette element 52 is connected to a plurality of central cassette elements 54 and a closing cassette element 56 and fastened together with fixing means 72, preferably rivets, shown in this cross-sectional representation. The balcony floor structure 42 thus formed is likewise fastened to the carrier profile frame 10 with fixing means 72 (not shown here), preferably rivets. The visible from below section of the balcony floor bottom 402 forms the visible balcony floor 48, unless this section is covered by an additionally provided panel.

FIG. 3 shows a carrier profile of the balcony in a perspective view. The carrier profile 12 is the result of a forming process of a thin sheet after six bending operations. On the balcony floor support 44 is when mounting the Balconies a portion of the balcony floor bottom 402 not shown in this figure placed on the floor covering support 461 of the support profile, a balcony floor covering 46 not shown here is placed in the balcony assembly. The lower U-shaped section is by folding a structural part of the C-shaped support profile on the short horizontal side. This U-shaped section forms a water drainage section 34. This water drainage section 34 continues over the other carrier profiles 14, 16, 18 in the entire carrier profile frame 10. He takes the trapped by the trough-shaped cassette elements 50 and guided into the carrier profiles water and dissipates it.

FIG. 4 shows a cross-sectional view of the attached by means of a holding system on a building wall carrier profile of the balcony with four vertical uprights. The first carrier profile 12 has at least one hole in its vertical section in the present cross-sectional view. Through this hole, the support section 12 is connected by means of a holding system 32 comprising a screw and two washers with a likewise having a hole building wall. The load on this balcony is mainly absorbed by the vertical uprights. The holding system 32 is only used for laterally fixing the support profile frame 10 to the building wall 30. The water drainage section 34, the floor covering support 461 of the support profile and the balcony floor support 44 already applies accordingly in this figure.

FIG. 5 shows a central cassette element of the balcony in cross section. The middle cassette element 54, like the carrier profile 12, is the result of a forming process of a thin sheet after six bending operations. A pair of coupling legs 64 extend from a base 60 on the left edge of the base 60. An engagement leg 641 extends from the left edge of the base 60 and an overlapping leg 642 extends from the right edge. The engagement leg 66 and the overlapping leg 68 are at a coupling leg angle A of 60 to 70 degrees to the base 60 arranged. Along the extension direction E of the coupling leg angle A due to the bending process is the same size. Of the When viewed from the base 60, the end portions of engagement legs 641 and over-reach legs 642 each form a coupling region 62. Each coupling region 62 has two sections: a first section is parallel to the base as a result of the bending operation. As a result of the fold, a second section extends at right angles to this first section and towards the base 60 and forms the termination of the coupling region 62. The engagement limb 641, the overlapping limb 642 and its two sections of the coupling region 62 extend uniformly along the extension direction E as a result of the bending. The interaction of the coupling regions 62 of Eingreifschenkel 641 and Übergreifschenkel 642 is together with FIG. 9 explained. The underside of the base 60 forms in particular the visible balcony floor 48 of the balcony floor underside.

FIG. 6 shows a center cassette element of the balcony in a perspective view. It can be seen very clearly that the coupling leg angle A is constant along the extension direction E as a result of the bending. The engaging leg 641, the overlapping leg 642 and the two portions of the coupling portion 62 are formed as shown in FIG FIG. 2 and 5 described.

FIG. 7 an initial cassette element of the balcony in perspective view. The initial cassette element 54 is the result of a forming process of a thin sheet after four bending operations. In contrast to the middle cassette element 54 FIG. 6 extends here as a coupling leg 64 only the engaging legs 641 from the left edge of the base 60. The engaging leg 641 is formed as in FIG. 5 described. The other leg is an initial leg 66. The starting leg 66 is formed from a single section that extends substantially perpendicularly upwardly as viewed from the base. Along the extension direction E, the starting leg 66 extends uniformly due to the bending. It prevents the water impinging from above (eg rainwater) running uncontrollably in the direction of the carrier profile frame 12. This channeling of the water is part of the drainage system of the balcony. Further, the initial leg 66 increases the Torsional rigidity and thus the stability of the initial cassette element 52nd

FIG. 8 shows a closing cassette element 56 of the balcony in a perspective view. The final cassette element 56 is the result of a forming process of a thin sheet after four bending operations. In contrast to the central cassette element 54, only the overlapping leg 642 is formed here as a coupling leg 64 on the right edge of the base 60. The overlapping leg 642 is formed as in FIG FIG. 5 described. The statements made there apply accordingly. The other leg disposed on the left edge of the base 60 is a terminator leg 68. The terminator leg 68, like the starting leg 66, is off FIG. 7 formed substantially vertically upwards. Everything about the beginning leg 66 off FIG. 7 The same applies accordingly to the end leg 68.

FIG. 9 shows a balcony floor structure formed from three cassette elements 42 without balcony flooring. The balcony floor structure 42 is formed from the in FIG. 7 described initial cassette element 52, and in the Figures 5 and 6 described center cassette element 54 and the in FIG. 8 described final cassette element 56th in the FIGS. 5 to 8 The statements made apply accordingly and will therefore not be repeated here. These three cassette elements 52, 54, 56 are adjacent and partially overlapping each other. In overlapping areas, specially shaped form-fitting sections 70 are arranged. The structural design, in particular of the overlapping legs 642 and the engaging legs 641 is the result of the already mentioned Abkantungsprozesse and allows for balcony mounting the structure of the balcony floor structure 42 of form-fitting interconnected cassette elements 50. Each of the three cassette elements 52, 54, 56 has at least on the engaging legs 641st with a first form-fitting section 701 and a second form-fitting section 702 or via the overlapping leg 642 a first form-fitting portion 711 and a second form-fitting portion 712. The first form-fitting portion 701 of the engaging leg and the first form-fitting portion 711 of the overlapping leg are arranged at a defined distance and parallel to the base 60. Extending substantially perpendicularly therefrom, in the direction of the respective base 60, the second form-fitting section 702 of the engaging leg and the second form-fitting section 712 of the overlapping leg. The two form-fitting sections 702, 712 in each case form the conclusion of the engagement leg 641 or Übergreifschenkels 642. The four form-fitting sections 701, 711, 702, 712 extend as sections of the engaging legs 641 or Übergreifschenkel 642 due to Abkantungsbedingt also along the extension direction E. In the region of the beginning leg 66th of the initial cassette element 52 and the end leg 68 of the end cassette element 56, the base 60 rests as a component of the balcony floor underside in the carrier profile frame 10, not shown in this figure, on the balcony floor covering 44 there.

Furthermore, each overlapping leg 642 has a floor covering pad 462 of the cassette element. This floor covering support 462 is arranged at a defined distance from the base 60 and formed from the upper side of the coupling region 62 of the overlapping limb 642 that is parallel to the base 60. On this floor covering support 462 of the cassette element is a, as in FIG. 2 described, not shown here balcony flooring can be placed.

FIG. 10 shows a positive connection of two adjacent cassette elements of the balcony in an enlarged view. The region which forms the positive connection between engagement limb 641 and overlapping limb 642 is hatched for clarity. The hatching does not constitute a component provided in addition to engaging legs 641 and overlapping legs 642. Hatched portions of overlapping legs 642 and engaging legs 641 are shown, which are positively coupled in a common form-fitting section 70. The common positive connection section 70 is formed from four individual Sections. The engagement leg 641 extends away from the base 60 of the starting cassette element 52 in a coupling leg angle A. The engagement leg 641 has the combination of the first form-fitting section 701 and the second form-fitting section 702 at its end section as the coupling section. The first positive engagement portion 701 is parallel to the base 60 and is directed away from the base 60 on the top of the engagement leg 641. The second form-fitting section 702 extends substantially perpendicularly away from the first form-fitting section 701 and extends in the direction of the base 60.

From the base 60 of the initial cassette element 54, the overlapping leg 642 extends away from the base 60 in a coupling leg angle A. The overlapping leg 642 has at its end section the first form-fitting section 711 and the adjoining second form-fitting section 712. Both form-fitting sections lie in the coupling region of the gripping leg 642. The first form-fitting section 711 runs parallel to the base 60 and is directed on the underside in the direction of the base 60. The second form-fitting section 712 extends substantially perpendicularly from the first form-fitting section 711 in the direction of the base 60. The two form-fitting sections 711 and 712 of the overlapping leg 642 come to lie on the two form-fitting sections 701 and 702 of the engaging leg 641 and form the common form-fitting section 70 with their contact surfaces out.
