Definitions

  • the invention relates to a fastening for roof sealing sheets laid on an insulation, which together form a roof sealing, nails or screws being provided in the seam region between two sealing sheets, which penetrate through the insulation into the roof support structure.
  • the classic roof structure is as follows: Insulation is laid on a roof support structure, with the roof waterproofing above. The roof seal must be secured on the insulation against attacking wind loads. This used to be done with a weighting. Gravel, for example, serves as a suitable weighting agent. However, the layer of gravel on the roof is very heavy. This has repercussions on the roof support structure and on the roof insulation. I.e. both the roof support structure had to be made more stable and the insulation.
  • the lightweight roofs are essentially characterized in that a kind of corrugated iron belongs to the roof support structure.
  • the corrugated sheet has in itself a round sheet profile that goes back and forth in cross section.
  • Modern sheets have a trapezoidal sheet shape.
  • the sheets are laid on a lattice structure.
  • the insulation lies on the sheets.
  • the lightweight construction method does away with weighting agents such as gravel in particular. Nevertheless, the roof seal on the insulation needs to be secured against wind loads. Without sufficient security, the roof sealing would blow off the roof in a very short time and be destroyed.
  • the protection against wind loads is formed on conventional roofs by brackets. This is a fastening method that has been in use for decades.
  • the usual holders have a plate, through which a screw penetrates the roof seal and through the Isolierurg into the roof support structure and presses the plate against the roof seal. So that no surface water penetrates through the roof sealing on the holders or plates and screws or nails, if necessary, the individual roof sealing sheets are laid so that they overlap in the overlap area compared to the weld seam connecting the two sealing sheets. The roof waterproofing can then be easily attached to the overhang on the underside.
  • the invention has for its object to avoid such leaks.
  • the invention is based on the consideration that the lack of fastening is generally not due to assembly errors, but to difficulties inherent in the system.
  • the invention is based on the knowledge that the usual materials for the insulating layers lose so much elasticity after a more or less long or short time that the roof seal between the holder and the insulating layer is no longer sufficiently secured.
  • the invention is based on the knowledge that the conventional method of fastening is unfavorable even when the insulating layer is sufficiently elastic. The unfavorable conditions result from the high strength of conventional brackets and the comparatively low strength of conventional roofing membranes.
  • One way is to improve the quality of the insulating material, combined with an increase in the strength of the roof sealing or alternatively an improvement in the holder.
  • the invention takes a different approach.
  • the invention uses a technology known per se elsewhere on the roof. This is the connection area of the roof sealing on the parapet. On the parapet, it is common to provide a sheet metal edge.
  • the edge of the sheet is primarily used for a visually clean finish.
  • the roof seals are glued to the sheet metal edge.
  • a bituminous adhesive or often also a plasticization of the waterproofing membrane on the contact surface with the sheet metal and sufficient pressing against the sheet metal are used.
  • damage to the roof waterproofing has so far been predominantly and in all serious cases visible in the edge area of the roof waterproofing.
  • the connection of the roof sealing to the parapet had to be regarded as extremely difficult.
  • the invention has overridden this.
  • sheets are provided in the seam area of two corresponding roof sealing sheets. First, the sheets are attached to the insulation.
  • the sheet can optionally pass through a bath with molten plastic; alternatively, the plastic can also be applied evenly in powder form and melted on the sheet after it has been applied.
  • the roof seam is fixed in a very advantageous manner. It can be assumed that the sheet undergoes much less movement than conventional holders. While conventional brackets are moved back and forth depending on the attacking wind loads and the direction of deformation of the roof waterproofing and thereby upturn the plates belonging to the roof fasteners, it is no longer to be expected that the sheet metal strip according to the invention will be upturned. According to the considerations on which the invention is based, edging in particular is considered to have a considerable disadvantageous effect. When edging, a plate edge of the holder is pressed into the underlying roof seal and insulation layer. At the usual low thicknesses, the edge of the plate has the effect of a blunt knife. Furthermore, the insulation layer underneath experiences a constantly changing compression. This is very disadvantageous for the permanent elasticity of the insulating layer.
  • the sheet metal strip according to the invention is especially defined when the attachment is carried out on both edges.
  • a zigzag line of the attachment points is also advantageous. I.e. the attachment points are not directly opposite one another at the sheet metal edges, but are offset by any amount, preferably by half the distance between two attachment points on the edge.
  • the corresponding edges of the roof sealing sheets are glued or welded over the entire surface of the sheet metal strip according to the invention.
  • the roof waterproofing membranes adhere to the edges along their edges with a weld seam width or adhesive seam width of 3 to 5 cm.
  • the fastening according to the invention provides a very advantageous perspective for the edge area of the roof seals: Increasingly, more attachment points per m2 are required in the edge area of the roof seals. With the usual type of fastening, the fastening points are located in the overlap area of the roof sealing sheets. The lower edge area of a roof waterproofing membrane is pressed against the insulation using the roof fastener or holder. The upper edge of the roof seal overlaps the sealing membrane edge provided with holders and is welded to the other sealing membrane beyond this sealing membrane edge.
  • the required fastening points per m2 cannot be achieved by providing a single seam with a holder in the holder in the edge area. A minimum distance is usually left between the holders. Due to these circumstances, the demand for more brackets per m2 can only be met by laying additional seams in the edge area of the roof waterproofing. As is known, preferably the seams form the risk of sealing roof seals. Therefore every additional seam is an additional risk. In addition, an additional seam requires considerable construction effort. The additional effort includes double material in the overlap area. This is a strip of e.g. B. 15 cm width over the entire length of the seam. The additional effort also includes the additional weld to be made.
  • the fastening according to the invention has much better values than the conventional fastening. Therefore, the number of attachment points can be significantly reduced compared to conventional attachments with the same quality of attachment. With the same number of attachment points, there is a much stronger attachment. This very often eliminates the need for an additional weld seam, thus avoiding the above. Risk and the extra effort.
  • the web edges are preferably butted against one another on the sheet metal strips according to the invention. It is usually irrelevant whether the sheet edges are adjacent to each other or partially spaced apart on the sheet stripes lie on. In principle, a distance can also be selected. The distance can arise if a sheet width is selected that bridges two beads in the trapezoidal sheet below. Then it may be expedient to arrange the web edges at a distance from one another in order to utilize the width of the sheet metal strip as far as possible.
  • Sheet metal strips with a minimum width can also be selected.
  • the minimum width is the width necessary to attach the sealing membrane edge. In the case of waterproofing membrane laid on butt, this is twice the width of the weld seam; at z. B. 4 cm weld width 8 cm wide. Added to this is the edge strip necessary for setting the screws or nails, e.g. B. 2 cm.
  • tabs can also be selected. The tabs are either integrally formed or are subsequently attached to the sheet metal strip. Forming is optionally carried out using a sheet metal strip with a very wide starting width that also covers the tabs. This starting strip is then trimmed (e.g. stamped out on the side) so that only the tabs remain on the edge of the sheet metal strip.
  • tabs are preferably done by welding. All strength requirements are taken into account with simple and quick spot welding.
  • the holes are also offset in the longitudinal direction of the sheet metal strip.
  • edge strips of the corresponding sealing strips to be welded are fastened to the sheet metal strip not overlapping but overlapping one another.
  • a sealing sheet is prefabricated with the sheet metal strip. I.e. is delivered in a prefabricated form. In this form, the metal strip is already attached to one of the web edges to be welded. The sheet metal strip is then laid out together with the waterproofing membrane. In this embodiment, however, the zigzag attachment can not be in the form as in the above. Realize separate laying of the metal strip.
  • the ceiling of the sheet metal strip according to the invention is at least 0.1 mm, preferably between 0.3 and 0.5 mm.
  • the sheet metal strip width is preferably greater than 120 mm.
  • tabs they are at a distance from a sheet metal strip edge to the adjacent tab of preferably 300 to 1500 mm.
  • Each tab has two or more openings for inserting screws or nails. The openings were punched out during the manufacture of the tabs.
  • a multi-part screw is selected in a further embodiment of the invention.
  • the multi-part screw differs from conventional screws in that it uses a shank that is provided with a small head and can be inserted into appropriately sized openings in the metal strip.
  • the screws can be countersunk in the shaft.
  • the seat of the screw head with the shaft is optionally placed deep in the insulating layer.
  • the shaft has the advantage that different insulation layer thicknesses can be operated with the same screws. Then the resulting differences with different shaft lengths are taken into account.
  • the shaft is preferably made of plastic, but can be made of steel.
  • spacers in the insulating layer are advantageous.
  • the spacers prevent the fastening from weakening when the insulation material loses elasticity.
  • Sleeves or pins are suitable as spacers.
  • the pins are expediently connected to one another by means of webs.
  • Sleeves and pins are pressed into the insulating material in such a way that screws or nails are arranged between the pins or in the sleeve during the subsequent fastening of the sheet metal strip.
  • a trapezoidal sheet 1 is shown from a roof support structure.
  • the plastic is an ethylene copolymer-bitumen mixture.
  • the sealing sheets 3 and 4 meet in the area 5.
  • the area 5 forms a seam.
  • a sheet 6 is laid on the insulating layer 2 below the edge strips belonging to the sealing sheets 3 and 4.
  • the sheet 6 spans two beads of the ble in the embodiment ches 1.
  • the screws 7 penetrate the sheet metal strip and the insulation 2 and the sheet metal 1.
  • the screws 7 are self-tapping sheet metal screws. This makes predrilling unnecessary.
  • the sheet 6 is a sheet with a thickness of 0.25 mm, which is coated on both sides with polyethylene.
  • pins 8 are countersunk in the insulating material.
  • 3 pins 8 are provided for each screw.
  • the pins 8 are arranged evenly distributed on a circumference and connected to one another at the top by a web.
  • the pins 8 form with the web a spacer, which is pressed with the laying of the sheet metal strip 6, before the screws 7 are placed in the insulation material 2.
  • the spacer consists of a rigid plastic, can also be made from injection molding, and ensures a constant locking of the metal strip 6 for the life of the roof even with low-quality insulation material.
  • the edge strips of the sealing sheets 3 and 4 are welded to the sheet metal strip 6 in the area of the seam 5.
  • the 2 welding seams are labeled 10 and 11.
