Abstract

The standing seam roof (11) comprises multiple profile metal sheets (13) for fixing to a substructure, and a cladding surface (17), which is formed between two longitudinal edges. The former edge comprises a standing seam (23), which is projecting with a concave shaped portion (25) towards the outer side of the profile metal sheet and on the inner side.

Description

Field of the invention

The invention relates to a standing seam covering according to the preamble of claim 1 and a sliding holder according to the preamble of claim 18.

State of the art

It is not possible to fix the individual elements of a Falzblecheindeckung immovable to a pad, since the individual roof elements are subjected to large thermal expansion, in particular by sunlight. From the free prior art, therefore, a variety of ways for the slidable mounting of Falzblecheindeckungen are known, which compensate for the thermal expansion of the individual roof elements.

In the EP 1 069 256 discloses a sliding holder for profiled sheet stand seam roofing membranes. The sliding holder has a foot part, which can be fastened to a substructure, and a head part, which can be displaced with respect to the foot part. The headboard has a sliding foot. The sliding foot stands with a standing surface on the foot part and is guided with a rail. Between rail and Gleitfuss there is a lateral clearance, which allows a shift of the Gleitfusses with respect to the rail transversely to the rail direction and thereby also allows rotation. As a result, the required precision when moving the sliding holder is less high and reduces the shear load of the mounting screws. The foot part is about 20 to 35 cm long and therefore on the one hand can bridge a deep bead of a trapezoidal sheet metal and on the other hand gives sheet metal tracks of 50 meters and more enough room for expansion. However, the construction of this slide holder is relatively complicated. This inevitably leads to increased production costs. Furthermore, the respective slide holder must be mounted before the respective roof element is attached to this. The position of the slide holders must therefore be precisely measured in advance.

A simple way of a sliding mount is in the EP 1 249 556 disclosed. Characterized in that at the respective profiled sheet web of a roof covering along the longitudinal flange, which is overlapped by the adjacent profiled sheet web, a plurality of slots are provided. By at least two of the slots screws are passed, which serve the slidable fixing of the profiled sheet web to the ground. Thus, the profiled sheet is on the one hand reliably fixed by means of screws on the ground and on the other hand is displaceable relative to the screws, a sliding clamp or a washer and a support plate is arranged between the screw head and slot. However, this bracket design has the disadvantage that for the flexible fixing of the roof elements, a plurality of slots must be present. Also, the longitudinal displacement of the roof elements is limited by the length of the slots.

Object of the invention

Object of the present invention is therefore to provide a cost-effective roof element holder. Yet another object is that the determination of the holder on the ground as quickly as possible, so without high precision requirements for the placement of the holder is feasible. Another object is that the thermal expansion of the individual roof elements is made possible by the holder without restriction.

description

According to the invention the object is achieved in a device according to the preamble of claim 1, characterized in that the holding plate is U-shaped by a first leg and a second leg of the slide holder, and that the slide holder with a third leg connected to the first leg between the second Stehfalzsteg and the holding web engages. This is especially important with long profiled sheet web whose thermal expansion can be considerable. The slide holder works like a rail, along which the profiled sheet metal sheet is guided and can expand unrestricted. Another advantage of the slide holder is that the profiled sheet tracks can extend almost noiselessly along the slide holder due to the unrestricted rail-like guidance. The usual noise in standing seam coverings noise during the expansion of the profiled sheet metal tracks is therefore prevented. Furthermore, proves the attachment of the profiled sheet tracks to the substructure by means of a plurality of pushers as very easy and quick to carry out. Unwanted transverse displacements of the profiled sheet web are prevented by the third leg. The length of the third leg is dimensioned to protrude sufficiently between the second standing seam ridge and the retaining web to prevent the profiled sheet web from transverse displacement, but not longer than necessary to minimize material costs. The sides of the first and third legs, which face the second leg, can be made ribbed in the longitudinal direction of the sliding holder. As a result, an improved sliding of the profiled sheet web is ensured along the slide holder. Especially when the slide holder and the profiled sheet metal tracks are made of aluminum, an increased frictional resistance between the slide holder and profiled sheet is prevented by the longitudinal corrugation.

In a particularly preferred embodiment, the holding plate is free of fastening openings. The production cost of profiled sheeting is thereby significantly reduced. A variety of provided at regular intervals along the entire length of the retaining plate slots, as they are otherwise necessary for the flexible fixing to the substructure, are therefore superfluous. It is conceivable, however, that profile sheet tracks, which already have slots described, are combined for attachment to the base with the at least one slide holder.

Advantageously, the U-profile has a first leg, with which the U-profile can be placed on the flat substructure, a second leg, which extends parallel or substantially parallel to the first leg and shorter than the first leg and a third leg formed by the free end of the first leg extending at right angles in the direction of the second leg. This simple design of the sliding holder, this can be adapted during manufacture without effort to the dimensions of the profiled sheet metal. The slide holder fulfills the task of holding the profiled sheet web with a simultaneous unrestricted longitudinal displacement and avoiding transverse displacement of the profiled sheet web.

In a preferred embodiment, an opening between the free end of the second leg and the third leg as well as a gap between the first and second legs are dimensioned to snap in place allow the holding plate and the holding web under elastic deformation of the holding plate and / or the second leg. The sliding holder is therefore not necessarily pushed onto the retaining plate, but can also be snapped on directly at the mounting point on the retaining plate.

In another preferred embodiment, an opening between the free end of the second leg and the third leg as well as a gap between the first and the second legs are dimensioned so that they allow only a sliding movement of the retaining plate in profile sheet longitudinal direction. In this case, the tolerances between the slide holder, retaining plate and retaining web are lower, which leads to an even stronger bracket between profiled sheet and sliding holder.

In a preferred embodiment, a plurality of first through openings are provided on the first leg and a plurality of second through openings are aligned in pairs, the diameters of the first through openings being smaller than a head of a fastening means and the diameters of the second through openings being greater than the head of the fastener are. The special dimensioning of the passage openings allows the individual attachment means to be inserted through the second passage openings and the head of the attachment means to rest on the first passage opening. The space between the first and second legs is therefore free to receive the retaining plate.

Conveniently, fastening means are provided with a head and a shank for fastening the sliding holder on the base. An attachment of the slide holder to the base is done quickly with conventional fasteners such as screws or nails.

Due to the fact that the diameters of the first through openings are larger than the shaft of the fastening means but smaller than the head of the fastening means, the sliding holders are reliably fixed to the substructure.

As stated above, the length of the first leg expediently corresponds substantially to the width of the holding plate. This is the profiled sheeting Sliding easily in the slide holder and still has little play.

In a particularly preferred embodiment, a mounting flange is provided on the side of the U-profile, which faces away from the profiled sheet metal web. Accordingly, the position of the sliding holder on the substructure does not have to be determined prior to assembly of the profiled sheet metal tracks, but is predetermined by the profile sheet trays laid one after the other on the substructure. Only after the equipped with the mounting flange slide holder is pushed onto the retaining plate, this is fixed with fasteners on the substructure.

Advantageously, the mounting flange is formed by the fact that the first and second leg are superimposed in a region which projects beyond the width of the retaining plate. The sliding holder is therefore quickly and cheaply produced from a sheet metal train.

It is also possible that the slide holder is made in an extrusion process. The extruder leaves a profile with the cross section of the slide holder. This extruded profile is then subdivided into a plurality of sliding holders of appropriate length. The preferred material for the extrusion process is aluminum or an aluminum alloy, although all other extrudable metals and alloys can be used.

Conveniently, the first and second through holes are provided on the mounting flange and aligned in pairs, the first and second through holes preferably having a diameter which is smaller than the head of the fastener and larger than the shank of the fastener. The sliding holder is therefore in particular after it has been pushed onto the retaining plate, fixed to the substructure with the fastening means.

Advantageously, the slide holder is made of a single sheet metal strip. This considerably reduces the manufacturing costs of the sliding holder.

In a further embodiment, the sliding holder is in two parts, wherein the first and third leg forms the first part and the wide leg forms the second part. This is of relevance if the profiled sheets are made very long. Due to the bipartite of the slide holder, it is possible to arrange the first and the second part directly to the mounting location on the retaining plate without the Slide holder would have to be postponed for a long time. It is understood that one-piece embodiments can be dimensioned so that they can be attached directly to the mounting location on the retaining plate. However, the tolerances which are predetermined by the holding plate, must be inevitably increased.

In order to provide sufficient space for the slide holder under the laid on the substructure profiled sheet tracks, a bead is provided following the first Stehfalzsteg whose height and width provide space for receiving the slide holder, which serves to attach the adjacent profiled sheet.

A further aspect of the invention advantageously relates to a holder provided above the roof surface, which is approximately N-shaped and thus has two webs directed parallel to one another and a bridge connecting the webs, recesses being formed on the webs for receiving the head formation of a standing seam , so that the holder is pushed onto a standing seam. This holder has the advantage that it can be arranged on any standing seam of the roofing without damaging the roofing in any way.

Preferably, at least two mutually aligned bores are provided on the webs in the region between the indentations and the bridge of the holder profile. The webs of the holder, in particular the indentations can be pressed with pressed parts, in particular screws, against the head training on standing seam. The roofing is therefore not damaged by fasteners, since the determination of the holder is based solely on clamping forces.

Yet another aspect of the invention relates to a sliding holder, which advantageously has a first leg which is to be arranged under the retaining plate of the profile sheet has a second leg, which is to be arranged above a retaining plate of the profile sheet, wherein the legs of the sliding holder a space for the retaining plate U Preferably, a third standing leg is formed on the first leg, which projects at a distance from the free end of the second leg and perpendicular to the first leg on the second leg, so that this projecting portion of the third standing leg between the second Stehfalzsteg and Retaining web to be determined profiled sheet web can be arranged. Further advantages and features will become apparent from the following description of an embodiment of the invention with reference to the schematic representations. It shows in not to scale representation:

A profiled sheeting is in the EP 1 249 556 disclosed. In this profiled sheeting, however, slots are provided on a mounting flange, which in the FIG. 1 are no longer shown. Through the slots fasteners are guided to set the profile tracks on the substructure.

The present invention relates to a standing seam covering, which is designated overall by the reference numeral 11 ( FIG. 4 ). The standing seam roofing consists of a plurality of profiled sheet metal sheets 13, as in the FIGS. 1 and 4 shown, and sliding holders in the form of U-profiles 15. The U-profiles 15 serve the longitudinally displaceable mounting of the profiled sheet metal tracks 13 to a substructure, not shown. Three different embodiments of the slide holder are in the FIGS. 2, 3 and 4 shown.

The profiled sheeting 13 has a clothing surface 17, which is located between a first and second longitudinal edge 19,21. At the first edge 19, a vertical Stehfalzsteg 23 is formed to which a concave shape 25 connects. At the second edge 21, a head formation 27 is formed, which of a further Stehfalzsteg 29 and a holding web 31 is worn. At the holding web 31 includes a holding plate 33 at. The retaining plate 33 may have double sheet thickness when the sheet is bent once down. This gives the retaining plate 33 sufficient stability against the effects of force caused by weathering.

Each profiled sheet 13 is held by a plurality of sliding holders 15 slidably on the base. The number of sliding holder 15 is dependent on the length of the profiled sheet metal sheets 13 and the expected weather conditions such as storm or snow loads. The slide holder 15 in the form of U-profiles, which in the FIGS. 2 and 3 are shown are bent from a sheet metal strip or produced by means of an extrusion process. Preferably, aluminum is used as the material, although other materials can also be used, provided that they meet the requirements of a standing seam roofing, in particular the requirements of temperature differences, climatic influences and strength. The slide holder 15 has a first leg 35 and a second leg 37, which runs almost parallel to the first leg. The first leg 35 rests on the substructure. The two legs 35,37 are spaced from each other such that the holding plate 33 is slidably received between the two legs. The first leg 35 is bounded by a third leg 39. The third leg 39 can be made in a simple manner by the open end of the first leg 25 is bent by 90 degrees in the direction of the second leg 37. The first leg 35 is bent at one point to the third leg 39, so that the length of the first leg 35 is dimensioned so that the retaining plate 33 is still slightly displaceable in the slide holder 15, but has no unnecessary leeway in the slide holder 15. If the slide holder 15 is produced by the extrusion process, then it goes without saying that the bending of the legs is eliminated. The profile, which is divided into the individual slide holder 15, already has the cross section of the slide holder 15 when it leaves the extruder. If the slide holder 15 is pushed onto the profiled sheet web 13, the third leg 39 projects into the intermediate space 41, which is delimited by the standing seam web 29 and the holding web 31. As a result, undesirable transverse displacements of the profiled sheet metal strip 13 relative to the sliding holder 15 are prevented. The slide holder 15 is fixed with fastening means 43, preferably tapping screws, to the substructure. The inner sides of the slide holder 15 may have a corrugation in the longitudinal direction (not shown in the figures) to improve the sliding properties of the slide holder.

In the embodiment, which in the FIG. 2 is shown, the slide holder 15 has a mounting flange 45, which is formed by the fact that the first and second legs 35,37 are pressed against each other. The width of the mounting flange 45 projects slightly beyond the diameters of superposed first and second through holes 47, 49 provided in the first and second legs 35, 37, respectively. Through the through openings 47,49 the fastening means 43 are guided, which define the sliding holder 15 on the substructure. It is immediately apparent that the diameter of the through holes 47,49 are larger than the shaft 51 of the fastener and smaller than the head 53 of the fastener.

In the embodiment, which in FIG. 3 is shown, the through holes 47,49 are provided centrally on the legs. The head 53 must therefore be recessed by the second leg 37, so that the fastening means 43 releases the space for receiving the retaining plate 33. In this embodiment, the diameter of the second passage opening must therefore be larger than the head 53.

As FIG. 4 can recognize, it is also conceivable that the slide holder 15 is made in two parts. The first and third legs 35,39 form the first part and the second leg 37 forms the second part. In the area of the passage openings 47, 49, the second leg 37 is received in a form-fitting manner in the first leg 39. The two parts are held together by the fastening means 51.

It is important that a bead 54 is provided on the profiled sheeting 13, which is arranged above the sliding holder 15. The bead 54 is dimensioned such that the underlying slide holder 15 finds enough space.

The mounting of the standing seam roofing 11 can be done very quickly and flexibly, since the position of the slide holder 15 is freely selectable along the retaining plate 33. Also, the individual slide holder 15 need not be set in advance on the base, but are pushed onto the profiled sheet 13 before the position of the profiled sheet 13 is fixed to the base by means of the slide holder 15.

Out FIG. 4 can be seen that in the assembled state, two adjacent profiled sheet metal tracks 13 are connected by the fact that the concave shape 25 of a second Profilblechblech the head formation 27 of a first profiled sheet web surrounds. This connection is used for attaching a holder 55. The holder 55 has the shape of a π-profile. At a bridge 57, two symmetrical webs 59 are arranged vertically. The webs 59 each have a bulge 61, which serves to receive the concave shape 25, when the holder is pushed onto the connection of adjacent profiled sheet webs. The distance between the two webs 59 is dimensioned such that the standing seam webs 23, 29 and the retaining web 31 find space between the two webs. The holder 55 is frictionally fixed to the standing seam. The clamping effect is generated by the two webs 59 are clamped together. On the webs 59 in the region between the bulge 61 and the bridge 57 through holes are provided (in the FIG. 5 not shown). For example, by screw-nut connections 63, which are received in the through holes, the two webs 59 are pulled together. The clamping effect is enhanced by the fact that the inner sides 65 of the webs 59 are fluted. The holders 55 may be disposed at any position of the standing seam roofing 11 at which a standing seam is located. This makes the holder 55 extremely flexible. The holders 55 can be used, for example, for holding gutters, roof end profiles or solar cells. Mentioned attachments are held on the holder 55 or a plurality of holders, for example, by means of screws or rivets on the bridges 57 are held.
