Description

The invention relates to a facade or facade cladding for slats, in particular rhomboid slats, and an associated correspondingly adapted fitting or fastening fitting for the attachment of the slats, in particular the rhomboid slats.

In a popular facade construction method, a substructure in the form of a flat framework made of wooden slats is attached to the outside of a building wall and on this a top layer of other wooden slats is screwed. The slats of the outer cover layer are arranged horizontally aligned at a small distance from each other.

Above all, for reasons of weather resistance, the cross-sectional area of the slats of the outer cover layer is not a rectangle but a rhomboid (parallelogram), which is why the short name "rhomboid slats" has come to be naturalized for this type of slats. When mounted rhomboid slats two lateral surface sides of each bar are vertically aligned and the other two lateral surfaces obliquely sloping from the inside of the cover to the outside sloping.

In the most common method of fixing the rhomboid slats of the top layer to the substructure, a screw is simply screwed through the rhomboid slats into the material of the substructure. To set the distance between adjacent rhomboid slats using spacers whose thickness is equal to the width of that gap, which should lie between adjacent rhomboid slats.

The AT 507 250 B1 describes a facade cladding with rhomboid slats, with an elongated, preferably metallic attachment fitting between rhomboid slats and substructure extends. The mounting bracket is connected to both the substructure and each with a rhomboid lath by at least one screw. The mounting bracket is considered "invisible" because When rhomboid slats are mounted, there is no part of the mounting bracket or any part of a screw on the visible side of the rhomboid slats. In addition to its "invisible" attachment function, the mounting bracket also offers the functions of the spacer for setting a defined distance between adjacent rhomboid slats and the spacer between substructure and rhomboid slats. These distances are desirable to avoid waterlogging. A disadvantage of the mounting bracket according to the AT 507 250 B1 is the relatively high workload during assembly.

The writings DE 10 2009 031 825 B4 . WO 2007051214 A1 and AT 509 874 B1 describe "invisible" fastening fittings for the attachment of planks, typically decking, on a typically horizontal surface, wherein the planks are arranged parallel to each other at a distance from each other. An attachment fitting extends both into the gap between adjacent planks and between these planks and the substructure.

According to the DE 10 2009 031 825 B4 have adjacent planks on the facing partial shell surfaces on a deep groove. That part of the fastening fitting which projects between adjacent planks is curved towards a plank in the shape of a hook and abuts against the lower groove flank of the groove on the partial jacket surface of the plank from above. From the lower groove flank of the facing part circumferential surface of the adjacent plank, a screw or a nail extends through the edge region of this plank and the underlying part of the fastening fitting into the substructure.

According to the WO 2007051214 A1 and the AT 509 874 B1 have adjacent planks on the facing partial shell surfaces at least a shallow groove. The attachment fitting is preferably made of a rubber-elastic material. That part of the mounting bracket, which protrudes between adjacent planks is formed bulged on both sides in the height of the grooves on the partial circumferential surfaces of the planks, so that it projects into the grooves on the partial shell surfaces of the planks. By screws, which are screwed normal to the substructure through the bulged area into the substructure inside, the bulges of the fitting are reinforced, whereby the bulges are pressed into the grooves on the planks, whereby the planks are fixed without a screw in them into or through them. To ensure that the distance between adjacent planks is correctly set during assembly, the planks must be pressed together by a tensioning device during assembly.

The NL 1008226 C2 describes the attachment of a paneling to a load-bearing wall, using a fastening fitting which extends into the gap between two vertically superimposed paneling elements and between the paneling elements on the one hand and the supporting wall on the other. The support part of the mounting bracket, so that part which extends on the wall, is flat and flat. The part of the fastening fitting extending into the gap between two paneling elements is narrow on the support part, widening upwards and downwards with increasing distance from the support part, so that a V-shaped groove is bounded at the top and bottom between this part and the support part , The wainscoting elements are held on the fastening fitting by projecting in each case one of the V-shaped grooves, each with a wall-side profile extension of their fastening fitting facing end faces and lie on the groove flanks. Turning away from the wall, the lower edge surface of the upper paneling element has, in addition to said profile extension, a groove into which a part of the fastening fitting projects. The upper edge surface of the lower paneling element is inclined away from the wall. The mounting bracket is held to the wall by a screw which extends through the mounting bracket into the wall at right angles to the wall. The paneling is quick and easy to install. However, the construction is not suitable to compensate for swelling and shrinkage of the paneling elements. Thus, it is only applicable to paneling elements made of swelling and shrinkage-free materials and in environments with quite limited temperature fluctuations.

The FR 2433087 A1 shows a construction method for a paneling of a wall, being used as fastening fittings aluminum extruded profiles which extend horizontally over the entire wall width and thus over several wainscoting, are fixed to the wall by means of screws and project with a narrow long profile web from the wall. From the far end of the profile web protrudes a short profile wall up and another short profile wall down. When mounted paneling this profile walls protrude into a respective groove on the front-side edge surface of a top or bottom adjacent to the aluminum profile paneling element. If the paneling elements swell after mounting, the bracket can reasonably compensate for this swell by bending the long narrow profile web up or down. However, the displacements of the paneling elements add up with the number of stacking paneling elements, which forces very long profile webs and thus a large distance of the paneling elements from the wall. The aluminum extrusions are fastened to the wall by means of screws, for which purpose the screws are drilled through a surface of the extruded aluminum sections. In order to improve the ease of installation, the said surface is not aligned parallel to the wall, but inclined ramp-like, so that the screws at an angle are aligned downwards. In order to prevent the aluminum extrusions from sliding down the wall as the screws are tightened, the contact surface of the aluminum extrusions with the wall is provided with a pointed ribbed profile which presses into the wall.

The object underlying the invention is to provide a construction method for a facade with a cover layer of slats, in particular rhomboid slats, wherein a slat, in particular rhomboid slat, on a substructure by means of several, compared to the slats short, "invisible Beschlägen "is anchored, as well as to provide a corresponding fastening fitting.

• Der Befestigungsbeschlag weist einen Auflagebereich und einen von diesem abstehenden Fortsatz auf, wobei sich der Auflagebereich zwischen die Unterkonstruktion auf der einen Seite und die Rhomboid-Latten auf der anderen Seite erstreckt und wobei sich der Fortsatz in den Spalt zwischen zwei benachbarten Rhomboid-Latten erstreckt.
• Der Fortsatz des Befestigungsbeschlages, welcher in den Spalt zwischen benachbarten Rhomboid-Latten ragt, hat einen Abschnitt, insbesondere eine Ausbauchung, welche in eine Nut an einer den Spalt begrenzenden Teilmantelfläche einer Rhomboid-Latte ragt.
• Ein länglicher Befestigungsteil, typischerweise eine Schraube oder ein Nagel, verläuft durch den Befestigungsbeschlag hindurch in das Material der Unterkonstruktion hinein, ohne dabei durch eine Rhomboid-Latte zu verlaufen.
• Jener Randbereich einer Rhomboid-Latte, bei welchem die den Spalt zur benachbarten Rhomboid-Latte begrenzende Teilmantelfläche mit der der Unterkonstruktion zugewandten Teilmantelfläche einen spitzen Winkel einschließt, wird durch den Befestigungsbeschlag gehalten, indem zwischen Auflagebereich und Fortsatz des Befestigungsbeschlages ein spitzer Winkel eingeschlossen wird und indem die besagten Teilmantelflächen der Rhomboid-Latte in diesen Winkelbereich hineinragen und an dem Auflagebereich und dem Fortsatz des Befestigungsbeschlages anliegen.

Further aspects of the invention are explained below:

• The mounting bracket has a support portion and an extension protruding therefrom, the support portion extending between the substructure on one side and the rhomboid slats on the other side, and the extension extending into the gap between two adjacent rhomboid slats.
• The extension of the fastening fitting, which projects into the gap between adjacent rhomboid slats, has a portion, in particular a bulge, which protrudes into a groove on a partial lateral surface of a rhomboid slat delimiting the gap.
• An elongated fastener, typically a screw or a nail, extends through the fastener fitting into the material of the substructure without passing through a rhomboid lath.
• That edge region of a rhomboid lath, in which the partial circumferential surface delimiting the gap to the adjacent rhomboid lath forms an acute angle with the partial lateral surface facing the substructure, is held by the fastening fitting by making a sharper point between the support region and extension of the fastening fitting Angle is included and by the said partial shell surfaces of the rhomboid lath protrude into this angular range and bear against the support area and the extension of the mounting bracket.

Furthermore, it is envisaged that the elongate attachment member (typically a screw or a nail) will not align normal to the substructure or parallel to those subcoat surfaces of the rhomboid battens which define the gap between adjacent rhomboid battens but at an acute angle to the plane to the substructure and Although directed to the height range of those rhomboid lath, limited to the gap between the two rhomboid slats part of the lateral surface with the sub-surface oriented towards the partial lateral surface an acute angle. As a supplementary measure to this end, the fastening fitting against compression deformation in the plane of the facade normal to the slat longitudinal direction elastically softer form than the rhomboid slats. In other words, it is proposed to elastically soften the fastening fitting against compression deformation in a direction lying in the plane of the facade and oriented normal to the slat longitudinal direction than the rhomboid slats.

In that the fastening fitting against compression deformation is "elastically softer than the rhomboid lath", it is meant that when a fastening fitting and a rhomboid lath are pressed against each other, the deformation of the fastening fitting caused by the resulting compressive stress is greater than the deformation the rhomboid lath, wherein the deformation is measured as an amount of dimensional change according to compressive force in the direction of compressive force.

According to a particularly preferred aspect of the invention, the fastening fitting is formed of a material which has a lower modulus of elasticity than the material of the rhomboid battens. This can be found with especially simple, very easy to handle and robust forms of mounting bracket Auslangen.

At the in Fig. 1 a detail of a facade according to the invention or façade cladding, a lower rhomboid lath 2 and an upper rhomboid lath 3 are fastened to a substructure 1 by means of a fastening fitting 4, wherein a screw 5 (as a special case of an "elongated fastening part") passes through the fastening fitting 4 the substructure 1 extends into it.

The mutually facing partial lateral surfaces 2.2, 3.2 of the two adjacent rhomboid slats 2, 3 are sloping sloping away from the substructure 1, so that impacting rain is always discharged to the outside, ie away from the substructure 1.

The fastening fitting 4 has a substantially flat support region 4.1, which extends between the rhomboid slats 2, 3 and the substructure 1. In addition, the fastening fitting 4 has an extension 4.2, which projects approximately from the center of the support region 4.1 into the gap between the adjacent rhomboid slats 2, 3. Since the gap between the adjacent rhomboid slats 2, 3 is not normal to the plane of the substructure 1, but inclined (in cross-sectional view), and the extension 4.2 of the mounting bracket 4 is not normal to the support area 4.1, but inclined. As a result, the extension 4.2 and the support region 4.1 on one side of the extension (namely the top side) define an obtuse angle and on the other side of the extension (namely the underside thereof) an acute angle (in cross-sectional view).

In the lower rhomboid lath 2, an acute angle is enclosed between the upper partial lateral surface 2.2 and the partial lateral surface 2.1 facing the substructure 1. This makes it possible, the lower rhomboid batten 2 - as shown - to hold at its upper edge by the mounting bracket 4 by facing with their standing at an acute angle partial shell surfaces 2.1, 2.2 in the acute angle range between the extension 4.2 and the Support area 4.1 of the mounting bracket 4 protrudes.

It is thus not necessary to equip the upper part of the lateral surface 2.2 of the lower rhomboid lath 2 with a groove for the engagement of the mounting bracket 4. Such a groove would be for optical reasons, for reasons of manufacturing costs and because of the risk that it may hold wet, disadvantageous.

In the case of the upper rhomboid lath 3, an obtuse angle is enclosed between the lower part-jacket surface 3.2 and the part-shell surface 3.1 facing the substructure 1. As a result, it is not possible to keep the lower edge of the upper rhomboid lath 3 similar to the upper edge of the lower rhomboid lath 2. One manages, by - as shown - the lower part of the upper surface 3.2 rhomboid batten 3 is provided with a groove 3.2.1, in which a portion of the extension 4.2, in the case illustrated a bulge 4.2.1 of the extension 4.2 of the mounting bracket. 4 protrudes.

The groove 3.2.1 has no significant disadvantages in this case. Waterlogging can not stand in it, since the entire part of the lateral surface 3.2 including all boundary surfaces of the groove 3.2.1 are aligned overhanging. Even visually, the groove is not visible when mounted facade because it can only be visible from a very limited angle and since it is also always in a shady area.

The fastening fitting 4 has a through hole 4.3, through which a screw or a nail or an equivalent elongated fastening part 5 extends and is anchored in the substructure 1. The through hole 4.3 is not normal to the plane of the substructure is aligned, but at an angle and in such a way that it is inclined into the substructure into the height range to that rhomboid lath 2 through which the fitting 4 at the acute angle between partial circumferential surfaces 2.1 , 2.2 is held. This results in a considerable advantage during assembly:

The rhomboid slats 2, 3 are successively mounted successively from bottom to top. The next upper rhomboid lath 3 is placed with its lower end face 3.2 on the extensions 4.2 of the already fixed by means of screws 5 to the substructure 1 mounting hardware 4, wherein the sections, in particular the bulges 4.2.1, the extensions 4.2 of the mounting hardware 4 in the Groove 3.2.1 on the bottom of the rhomboid lath and thus prevent the rhomboid lath from slipping. Then mounting brackets 4 are attached to the upper side of the added rhomboid lath so that they protrude with their support area 4.1 between the rhomboid lath and the substructure 1 and with that side of the extensions 4.2 abut the rhomboid lath, which with the support area 4.1 includes an acute angle. If now elongated fasteners 5 (screws, nails, etc.) are moved through the through holes 4.3 in the substructure 1, the respective mounting hardware 4 are moved toward the newly added rhomboid lath, bringing this rhomboid latte increased to the previously mounted, lower mounting brackets 4 is pressed and thus the fixation is improved. One saves thereby the entrance in connection with the WO 2007051214 A1 and the AT 509 874 B1 mentioned tensioning device.

Good experiences have been made when the fasteners 5 are inclined about 30 ° relative to the normal to the substructure 1. In any case, good results are achieved when the angle between the elongated attachment part 5 and the normal to the substructure 1 is slightly greater than the friction angle between the two friction partners attachment fitting 4 and substructure 1. (The friction angle is the arctangent of the quotient between the tangential force at the contact surface of two bodies pressed together and the normal force with which the bodies are pressed against each other when the two bodies are just not yet sliding together.)

By the fastening fitting 4 consists of a relatively soft elastic material, namely a material with a lower modulus of elasticity than that of the rhomboid lath, stronger downward movement of the fastening fitting 4 is achieved during tightening of the screw 5, as if the material of the mounting bracket 4 would be very hard. Furthermore, this ensures that the rhomboid slats are not damaged by high local pressure. The third and most important advantage is achieved in that the rhomboid slats 2, 3 swell and can disappear in the assembled state and the mounting hardware 4 still always fed to the rhomboid slats 2, 3. Swelling and shrinking of the rhomboid slats 2, 3 causes a reduction or enlargement of the individual gaps between the rhomboid slats 2, 3 and no displacement of the entire slat layer; it does not matter how high the facade is.

In a further preferred embodiment, a fastening fitting 4 made of a rubber-elastic material. By "rubber elastic material" is meant a material whose modulus of elasticity is significantly lower than the modulus of elasticity of the material of the rhomboid battens 2, 3 and which is non-destructively elastic in each Direction is deformable by at least 15% of its relaxed dimension in this direction. By the mounting bracket 4 is elastically biased to pressure between the individual associated parts substructure 1, lower rhomboid lath 2 and upper rhomboid lath 3, it is achievable that despite weather-related swelling and shrinkage of wooden parts of the facade all these parts at any time fit snugly on the mounting bracket 4 and be held firmly without being destroyed.

For reasons of ventilation, it is advantageous if the mounting bracket 4 is not fully applied to the surface of the support area 4.1 facing the substructure 1, but only via local elevations or webs. This can be achieved by fitting the fastening fitting 4 - as shown - on the side of the support region 4.1 facing the substructure 1 with wide shallow grooves 4.1.1. So that the fastening fitting 4 can nevertheless slide well on the substructure during tightening of the screw 5, the side of the support region 4.1 facing the substructure 1 should not be interrupted by grooves 4.1.1 in the vicinity of the screw through bore 4.

Except for details of the execution of the projecting into the gap between adjacent rhomboid slats 2, 3 extension everything applies to the mounting bracket 4 according to Fig. 1 and Fig. 2 also said for the in Fig. 3 and Fig. 4 , sketched mounting bracket 14 according to the second embodiment.

When fastening fitting 14 projecting from the support member 14.1 in the gap between adjacent rhomboid slats 2, 3 extension 14.2 split into two parts 14.2.1 and 14.2.2, between which extends a groove whose profile direction horizontally - ie parallel to the rhomboid Slats 2, 3 - runs and their cross-sectional area too the side facing away from the support part 14.1 side is open. The upper part 14.2.1 is formed as a section, in particular as a bulge, and projects into the groove on the lower end face of the upper rhomboid lath 3. The lower part is formed as a slender part extension 14.2.2 and then closes when the mounting bracket 14 is not elastically deformed, with the support member 14.1 an acute angle, which is slightly smaller than the acute angle between the upper end face of the lower rhomboid lath 2 and the voltage applied to the support member 14.1 surface of this rhomboid lath. 2

During assembly, the mounting bracket 14 is first placed on the lower rhomboid batten 2 that he compared to this in Fig. 3 held in full lines position. When the screw 5 is tightened, it slides against the rhomboid lath 2, so that the rhomboid lath 2 opposite the fitting 14 holds the dotted relative position shown. The lower part of the extension 14.2.2 is in this case ideally bent so far upwards that it rests with its lower surface fed on the upper part of the shell surface 2.2 of the lower rhomboid lath 2.

Due to the split in two parts 14.2.1, 14.2.2 version of the extension 14.2 and by the discussed with respect to the support member 14.1 particularly acute-angled arrangement of the partial extension 14.2.2 the required elastic deformability ("softness") of the mounting bracket 14 is particularly good then achievable if the material of the fastening fitting 14 per se has a rather high modulus of elasticity and a rather small elastic deformation range.

Even if the extension 4.2, which extends from the support part 14.1 into the gap between adjacent rhomboid slats 2, 3, is not split into two parts, it is advantageous due to the better elastic deformability, the acute angle between a Side of this extension 14.2 and the support member 14.1 of the mounting bracket 14 to be sized so that this angle is not sharpener in non-elastically deformed mounting bracket than the acute angle between adjacent surfaces of the rhomboid slats.

In the following description of the third embodiment of the facade or cladding according to the invention and the fastening fitting 24 according to the invention, only the differences with respect to the description of the second embodiment of the facade or cladding according to the invention and the fastening fitting 14 according to the invention will be discussed. The same or similar components or sections are provided with the same or similar reference numerals.

Further shows Fig. 6 a perspective view of the mounting bracket 24 of the invention Fig. 5 from a first side of the mounting bracket 24, whereas Fig. 7 another perspective view of the mounting bracket 24 of Fig. 5 from a second side of the mounting bracket 24 opposite the first side.
