Definitions
- the present invention relates to a Building envelope, especially a roof, with a load receiving substructure, a covering of profiles and corresponding holders, and bolt-shaped Fasteners connecting the bracket to the substructure connect tensile.
- Roof structures are known in which Spacer profiles or holders to accommodate a covering the supporting substructure is set and the thermal insulation between the brackets or spacer profiles.
- At Use of holders requires many holders through the Insulation boards are pushed through. So that the insulation boards can be pierced or the insulation without gaps to the Only holders or spacer profiles can be used Insulation boards are used.
- Such insulation boards are, however not tread-resistant and are partly up to the site utter destruction of the plate as a result of walking on the Insulation layer is inevitable during the construction process.
- the European Patent EP 0685612 proposed as a thermal insulation use solid mineral fiber board.
- To this Insulation is used as a spacer profile with a U-rail Thighs down from above into the mineral fiber board indented.
- the legs of the U-profile should be shorter be than the thickness of the mineral fiber board.
- the web of the U-profile is with bolt-shaped connecting elements with the Connected substructure.
- On the one with the top of the Thermal insulation flush web can now use different roof skin constructions be attached.
- Advantage of this Construction is that the insulation layer can be walked on without taking damage, and that the thermal bridges are massive are reduced.
- the one in this publication is also suitable shown substructure for each type of Roofing.
- this Construction is that with a single screw connection Covering can be attached to the substructure. Disadvantageous this construction is particularly the need for Formation of strips of reduced thickness in the Insulation layer. This is labor intensive and partially reduced the k value of the construction and increases the risk of errors when laying the insulation layer.
- a roof structure is also from the same article known in which holder in the area of the standing seam on a consistently trained in constant strength Thermal insulation made of foam glass and through the Thermal insulation is screwed through to the substructure.
- the Standing seam is formed with a wide space the support surface of the holder extends in the folding direction. The fastening screws are thus on the axis of the fold arranged and fall into the space in the standing seam.
- This holder and the corresponding, industrial manufactured profiled sheets advantageously allow a Consistently constant insulation thickness.
- this construction is in particular that the Fastening screws arranged in the axis of the fold are. The latter causes the holder forces across It is difficult to absorb the sliding direction and therefore only have a sufficient footing on a hard surface.
- the standing seam due to the large space in which place the brackets and mounting screws find, not be pressed.
- Unpressed rebates can be increased in windy weather Have noise emissions.
- the fasteners used for the tensile connection of the holder with the load-bearing substructure are with both roof constructions with foam glass conventional screws with a threaded section, one Head and at most a shaft.
- the screw depth is by the thickness of the incompressible construction (Insulation layer and holder foot) determined, the Thread section over the necessary for fastening Area goes out.
- the screws are in plastic screw sleeves with cover cap led to the thermal bridge about shrinking the screws so the Screw tips do not affect the dew temperature of the indoor air to reach.
- a disadvantage of the screws used is that these, especially in the trapezoidal sheet, can be turned and then no longer pull. An over-tightened screw always leaves a hole in the vapor seal and if the Holder is not shifted slightly moved, a gap in the range of fasteners.
- this is carried out on the Substructure lying modular tape with a module size the dimensionally correct division of the profiled sheet, and according to the division on the modular belt (29) Holder reached.
- the use of a modular belt makes it easier work with any covering from a modular dimension having profiles and corresponding holders.
- an elastically compressible insulation layer preferably mineral fiber boards made of rock wool or glass fibers
- a building envelope can be quickly and correctly isolated.
- Such plates can be in large formats with a high Laying speed can be butted.
- the result reduction in impacts compared to one Foam glass insulation and the proven tightness of these joints ensures an excellent, complete insulation layer at the same time very rapid construction progress and unproblematic processing.
- Adjustments can be made on the Construction site with knives or saws, patchy joints to components such as chimneys or exhaust pipes, Channels and windows and the like can be stuffed by hand become.
- mineral fiber boards combine the desired adaptability to irregularities of the Underground and the environment and an elastic Pressability with high compressive strength.
- Roof structures are preferred to be treadproof insulation, because walking on the insulation layer can hardly be avoided.
- the shaft length of the Fasteners is constant, so is the distance constant between covering and substructure. According to the Difference between the construction strength and that after Attachment beyond the base length of the shaft hence the insulation layer by the attached Fastener with a certain maximum pressure pressed.
- the one for tearing Predetermined breaking point in the retractable spreading the rivet Core required force and the compression resistance of the Insulation board constant. Therefore, when using of rivets instead of screws by choosing the Shaft length the pressure on the insulation board, or the extent the pressure of the insulation layer.
- Threaded form screw For the screw connection in sheet metal, solid steel or wood is expedient Threaded form screw provided. This expands, shapes or a thread cuts into the material in which they hold should.
- Metal substructures (from approx. 1.2 mm) are advantageous provided with a drill bit so that the Screw can be set, drilled and tightened. In order to the thread forming screw cannot be overtightened ends the thread in front of a shaft, which has a diameter has, which is not larger than the diameter of the Thread core is.
- the thread pitch is advantageous up to a Flattened screw axis normal plane. This will make the Tear resistance of the screw increases because of the screw an almost all-round and flat contact surface behind the Has opening. Such screws are under tension on the Screw can be unscrewed again.
- the screw depth can be screwed in full material, e.g. Full steel, by widening the Shaft can be achieved.
- the broadening is on the relatively hard surface. This will make it further Tightening the screw greatly increases the torque required.
- the Screw is tight when the thread is in the ground is screwed in so that the distance between the substructure and Screw head is constant.
- An advantageous covering consists of Sheet metal elements and corresponding holders.
- Sheet shares are a very dense and walkable roof covering with which all slopes, in limited areas even without a slope, can be covered.
- Sheet covers are light, cheap and quick to assemble. Because the Sheet metal covering lies on the thermal insulation Pressure forces passed directly to them. By wind This can result in noise emissions from the roofing can also be reduced because of a flutter of the Sheet covering is hindered by the adjacent insulation layer becomes.
- the Fasteners and the holder only need to be on the Suction load must be respected.
- the covering Holder for the covering a wide foot so that your Large footprint and thus the preload of the Fasteners caused pressure on the insulation layer low and the lever for power transmission to the Insulation layer is cheap. At most, the Support surface of the holder enlarged by a pad become. Holders attached above the covering use the large contact area of the sheet metal covering.
- a preferred covering consists of Profile sheets with standing seam. These are in almost any Lengths can be produced in profile rolling mills. This can also large roofs and facades in one direction with or without only individual impacts are covered. This reduces the Number of elements to be assembled and eliminates the number of the potential leaks.
- the folds can be done mechanically be designed compressible. These advantageously point out Profile sheet webs at least on one side to the standing seam Beading to hold the holder foot and / or heads of the Fasteners on. This allows fasteners with protruding heads, which are easier to handle as such with sunk, used, and one Touching the holder foot or fastener head and Profile sheet web is prevented. A friction between the Covering and fastening is excluded.
- Such a bead can be arranged on one side Bracket foot must also be one-sided. This is one continuous installation of the roof is possible, in which Laying alternately a sheet metal sheet and a series of Brackets can be mounted. However, one is preferred bilateral training of the holder foot and a corresponding symmetrical arrangement of the beads on both sides of the standing seam to accommodate the holder foot and the protruding parts of the Fasteners for the holder.
- Such a bead in the Profile sheet is in one without additional work Manufacturing process with the profiling of the sheet metal strip. It does not cause additional costs or disadvantageous Properties for the profiled sheet, but also acts stiffening on the profile.
- the thermal insulation advantageously consists of pressure-resistant mineral fiber boards.
- Mineral fiber boards are not rotten, resistant to heat, cold and Moisture and have good sound insulation values. Your Material properties are retained for a very long time. The damage to dismantled mineral fiber boards, which by penetrating the plates with bolt-shaped Fasteners caused can hardly be measured become. Non-slip mineral fiber boards are made by walking the plate is not damaged and can therefore very well be dismantled again.
- the mineral fiber board is expediently equipped, in particular for roof structures, with a lower layer with a lower ⁇ value and a load-distributing upper layer with a higher density. With an average density of approx. 130 kg / m 3 , such a plate already has sufficient pressure resistance and tread resistance for roof structures. Lighter material can be used for wall constructions.
- a preferred vapor seal consists of Elastomer bitumen sheets. These have an advantageous Elasticity and close where the Fasteners pierce them tightly against them. In particular, the locally increased pressure on the Elastomer bitumen sheet around the fasteners one Pressing the web in its thickness and thus an expansion in of their area, what the geomembrane to the bolt-shaped Fasteners presses. This process is through the heating caused by screwing in a screw additionally favored.
- gluing the Geomembrane with the underground and thanks to it Tear resistance is also guaranteed to have been committed Geomembrane, even in the area through the Geomembrane spanned deep bead of a trapezoidal sheet, possible without crack formation and displacement of the vapor barrier is.
- the foot of the holder is advantageous magnifying pad provided on which the holder are set. This ensures the stability of the holder enlarged. With an increased footprint, the holder can the insulation layer to be correspondingly softer and lighter what has a positive effect on their insulation ability.
- a modular belt with one is advantageous Dimensional division provided, the holder be set according to this division.
- the introduction can e.g. through markings or stops on the modular belt for the holders happen.
- Such a modular belt can very quickly and laid precisely. You only need one Profiled sheet, resp. measured a holder column and the Modular belts, usually laid parallel to the eaves become. From this column is through the modular belt for the entire roof determines the exact size of each holder.
- Such a modular belt can consist of a thin roll material Sheet metal, plastic or even paper can be produced. However, it is preferably made from sheet metal strips, which are capable of withstanding the loads that are borne by the holder feet to distribute something. Conveniently, on one such modular belt the edges matured, causing stiffness elevated.
- An intermediate layer does not only have an interrupting effect for the heat flow between the head and the holder base.
- the liner has a smaller opening than that Washer and the shaft diameter of the Fastener has, a collar forms around the Shaft. This will fix the fastener in the hole of the Centered holder so that the holder is aligned on the one hand and on the other hand also the heat transfer between the Shank of the fastener and the holder minimized because the shaft cannot touch the holder.
- FIG. 1 is the supporting substructure 13 with the steel beams 15 and Trapezoidal sheet 17 shown.
- the trapezoidal sheet 17 has Deep beads 19 and raised beads 21 in one regular distance 22 on.
- a vapor barrier 23 made of adhesive-active and tear-resistant Layed elastomer bitumen sheets. These are mutual and with glued the sheets of the raised beads 21.
- Preferred Elastomer bitumen sheets have a thickness of approx. 3 mm and are on the top with an aluminum layer to increase the Provide vapor resistance.
- Thermal insulation 25 made of rock wool is attached to the vapor barrier 23.
- the stone wool panels preferably in large formats of 120 x 200 cm, for example, are hard-wearing and water-repellent. They have an integrated two-layer characteristic. Its upper layer consists of fibers with a density of approx. 210 kg / m 3, which are mainly aligned parallel to the plane of the board. This layer is intended for load distribution. The lower layer has a high degree of fibers aligned perpendicular to the plate plane, which means that it can withstand high pressures with a low density.
- the plates advantageously have an average density of approximately 130 kg / m 3 . Their thermal conductivity ⁇ D is 0.038W / mK.
- the heat transfer coefficient k of the panel is 0.45, 0.36, 0.30 and 0.26 W / m 2 K, depending on the thickness of the panels of 80, 100, 120 or 140 mm.
- the rated structural sound insulation index R ' W is between 41 and 44 for the same delivery thicknesses dB.
- These plates are, as a rule, orthogonal to Descent direction, modular belts 29 laid parallel to each other.
- the distance between the module belts 29 depends on the calculated necessary density of holders, i.e. according to the expected suction load of the Roof covering on the one hand, on the other hand according to the distance 22 the beads 19.21.
- the modular belts 29 have a true-to-size dimension Punching on.
- the distances 31 of the perforation correspond to that Pitch 33 of the profile sheet covering 35.
- the perforation corresponds to the mounting holes in the feet 37 of the bracket 39 described below.
- the holders 39 are placed on the modular belts 29. The exact location is due to the perforation in the modular belt 29 given.
- the holder 39 have a protruding on both sides Foot 37 on each with a hole for screwing. By this hole and through the corresponding hole in the module belt 29 a screw 41 is inserted for assembly and pushed through the insulation layer 25 at right angles (see Figures 2 and 3). As a result, the screw 41 is set precisely and kept in place. If now with a screw drill Screw 41 is screwed in, the drill bit 43 drills Screw 41 through the sheet of the raised bead 21. This creates a funnel-shaped, flared downward Indentation in the trapezoidal sheet, in which the thread 45 of the Screw in screw 41.
- FIGs 2 and 3 are cross sections through the Construction and the holder 39 shown.
- In the left part is the cutting line across the slope, in the right part in Slope direction. It is shown, among other things, how the bead 51, which connects to standing seam 53, space for the Attachment of the holder 39 offers.
- Bracket foot 37 and Screw head 47 can be accommodated within the bead 51.
- the Standing seams 53 are suitable for being pressed by machine and slide over the holder 39.
- the screws 41 point a shaft diameter of approx. 5.5 mm.
- the holes in the However, holder feet are at least 7 mm.
- a washer 55 with permanent elastomer pad 56 (a so-called EPDM sealing washer with an ethylene-propylene-rubber layer) arranged (see also Figures 6 to 11).
- the elastomeric Pad or intermediate layer 56 is provided with a hole, which is smaller than the shaft diameter. This has the elastomeric material forms a collar 58 around the inserted screw shaft 49 bulged and prevented a touch of the shaft and holder base.
- a PVC plastic cap 59 which covers the screw head 47, prevents direct contact of the screw 41 with the Convection air and thereby reduces the heat transfer screw 41 from the warm to the cold side additionally.
- the temperature of the screw tip 43 lies through these measures even under unfavorable conditions the dew temperature for the humidity of the indoor air.
- the Screws 41 themselves are made of stainless steel (Stainless steel 1.4301). The small difference in the thermoelectric voltage series between this steel and The aluminum of the holder 39 closes electrical corrosion practically out.
- Figure 3 also shows an assembly with hidden Screw tips 43.
- a mounting plate 57 is on one Deep bead 19 of the trapezoidal sheet 17 riveted.
- the drill bit 43 is drilled through the mounting plate 57 and lies in the Deep bead 19 hidden from any view.
- the Mounting plate 57 is riveted to the trapezoidal sheet 17, whereby an insulating one to minimize the thermal bridges Intermediate layer 61 between mounting plate 57 and trapezoidal plate 17 is provided.
- the modular belt 29 preferably a slightly folded Has edge 65. With this bend 65 it works Module belt 29 in the surface of rockwool 25 without to hurt them and is therefore immovable. This Bend 65 also increases the rigidity of the modular belt 29 what for assembly on site and the ability to Transfer pressure forces from the holder to the insulation layer is advantageous.
- Figure 4 shows the box gutter profile Profile sheet 35 in cross section.
- the profiled sheet 35 has Different beads 67 and 69 parallel to the folding direction to stiffen the profile.
- the beads 51 to mention which directly on the channel wall 71 connect and thereby the fastening screw heads 47 and the holder feet offer 37 space, so that the gutter floor 73 can rest on the insulation layer 25, even if the Holder 39 are mounted on the insulation layer 25.
- FIG. 5 shows a rivet 40 with a retractable core 42, which the rivet 40 in Fastening area 44 spreads.
- the core 42 has one Predetermined breaking point 46, which at a certain Tensile load tears.
- the pull on the core 42 is e.g. by determines the compression of the thermal insulation.
- Such rivets 40 are suitable, the insulating layer 25 instead of screws 41 at the attachment points with a constant force press.
- the one predetermined by the predetermined breaking point 46 Breaking load presses the insulation layer 25 evenly the rivet shaft length at constant breaking load Extent of the pressure determined.
- Figures 6 to 11 show screws 41 with a Thread depth limiting thread termination 77.
- Die Screws 41 from FIGS. 6 to 8 assign one, normally the last screw turn 48 extending along the screw axis on thread 45. This turn 48 leaves a slot 50 open to the previous turn, so that the sheet in which the screw is screwed through slot 50 can slip through.
- the last turn 48 is however then almost all around flat on the sheet and transmits the forces evenly to the sheet 17 of the Substructure. However, from a certain sheet thickness, this is not more is possible.
- the last turn 48 then points, as in FIGS Figures 9 to 11 shown the same slope as that previous turns of thread 45.
- FIG. 6 An ordinary A screw 41 (Fig. 6) can screwed into 0.75 mm thick sheets without pre-drilling become. If you don't want to pre-drill thicker sheets, then an A screw can be used up to sheet thicknesses of 1 to 1.2 mm 41 with rolled tip (Fig. 7), up to a good 1.5 mm with notched tip 43 (Fig. 8) and above with a B screw use a drill bit 43 '. For thin sheets 17 to 2 mm, this drill tip 43 'can be tapered (Fig. 9), at it should be thicker corresponding to the thread core 52 Have diameter (Fig. 10).
- BR screws can each depending on the length of the drill bit 43 'to substructures of 12 mm can be used. From 3 mm thick substructure can a BZ screw 41 can be used ( Figure 11). For this a hole must be pre-drilled.
- the BZ screw 41 has a shaft 49 which is thicker than the thread core 52, so that the thread 45 cannot be screwed in deeper, than up to the widened shaft 49, which then on Borehole edge is present.
- all screws 41 for in sheets up to 4 mm ( Figures 6 to 10) through the Sheet 17 screwed through until the thread 45 no longer grabs and turns empty behind the sheet.
- These screws 41 accordingly have a shaft 49, which at most has the diameter of the thread core 52.
- the Screw head 47 can be hexagonal and / or with a hexagonal, star-shaped or cruciform depression be designed to accommodate a screw head.
- the screw head 47 can also be rounded and flat, which is appropriate to the danger a contact between the cover 35 and the screw head 47 to diminish.
- a roof structure as shown in Figure 1 is built up by using a binder 15 made of steel profiles Trapezoidal sheet formwork 17 laid and with the ties 15 is connected. On this supporting substructure 13 is a Vapor barrier 23 laid or glued, being embarrassed on it It is important to ensure that there are no leaks. Thereon are large-format and sturdy thermal insulation boards 25 in uniform layer thickness butt-laid. In this Construction status, the roof is fully accessible. On this flat surface is now a first sheet 35, resp. the locations for their holders 39, precisely measured, so that the holder 39 over the beads 21 of the Trapezoidal sheet 17 come to rest, or on the specially for the fastening of the holder 39 provided mounting plates 57 over the beads 19 of the trapezoidal sheet 17.
- one first column of holders 39 is advantageously a template used.
- This can be a network of cords with where an area of the roof is drawn in a grid pattern.
- This can be a panel with cutouts in which the Holder 39 can be set, or a band which the location of the Holder 39 determined in a row.
- a modular belt is preferred 29, which has a dimensionally accurate perforation.
- This Modular belts are usually laid parallel to the eaves.
- the perforation in the modular belt 29 advantageously contains this more sensitive and therefore more precise measurement. This is the module dimension of the profile sheet covering.
- the distance between the module belts 29 becomes Need and according to the distance 22 between the beads 19, 21 of the trapezoidal sheet 17 selected.
- the holder 39 set and through the holes in Module strap screwed through to the trapezoidal sheet 17.
- screws 41 are advantageously used, which are not can be turned over. These screws 41 are with a Washer 55 with an elastomeric pad Material populated through the holes in the holder foot 37 and Module tape 29 inserted and through the thermal barrier coating driven. With a drill tip 43, the screw 41 machine drilled through the sheet and into the sheet screwed until it turns empty.
- the thread edge presses the edge of the drilled hole back a bit and carries from now on the train of screw 41 on the something against that Thread 45 of the perforated edge of the trapezoidal sheet 17 from.
- the Profile sheet covering 35 hooked in and at most screwed to the brackets 39 at certain points.
- the Standing seams 53 are finally pressed by machine.
