Definitions

  • the invention relates to a retaining rail for holding down roofing membranes in flat roofs, according to the preamble of the first claim.
  • Flat roofs usually have a multi-layered structure and have essentially a supporting roof substructure, which in particular from a trapezoidal steel sheet, from stiffened wood panels or from steel respectively. Autoclaved aerated concrete can exist. Above this supporting roof substructure is usually a vapor barrier layer of bitumen, polymer bitumen or plastic. This vapor barrier layer is intended to delay or prevent the diffusion of water vapor into the thermal insulation and under the seal. On this vapor barrier layer is a thermal barrier coating, which may for example consist of mineral fiber fleece, polystyrene (PS), expanded polystyrene (EPS) or extruded polystyrene (XPS) and which in turn is covered with a roof skin.
  • This roof skin is usually made of several adjacent and welded together waterproofing membranes, which cover the roof watertight, ie protect it from penetrating water. These sealing membranes, resp.
  • Protective films are usually made of plastic sheets with filling and
  • Dyes provided plastics, such as PVC, PO, FPO or TPO. Because of the wind suction forces acting on the roof surface in windy weather conditions, these waterproofing membranes must be additionally secured on the roof. For example, these waterproofing membranes are glued to the thermal insulation or held on the roof with mechanical aids. A simple and commonly used method for keeping waterproofing membranes on the roof is to pour a 5 to 10 cm thick layer of gravel over the waterproofing membranes.
  • this type of mechanical roof-skin protection has the disadvantage that it is very weight-intensive and relatively expensive, ie the advantages of a flat roof construction (light, inexpensive and walkable) makes up for it again.
  • the Utility Model DE 20 2005 006 231 U1 describes a rail-shaped component for holding down a sealing strip, wherein the longitudinal edge zones have wall-shaped deformations or bends.
  • This has the advantage that the over the rail-shaped components mounted cover strips not directly on the heads of the Fix fasteners (screw or nail heads) and thus can be avoided that these fasteners damage the roofing membrane cover and may cause leaks. This is especially true when entering the flat roof on these rail-shaped components is entered.
  • Components or hold-down means with such wall-shaped deformations or folds prove to be particularly sure-footed.
  • such wall-shaped deformations or folds have the advantage that they give the rail-shaped hold-down means increased bending stiffness in the longitudinal direction. During assembly, they reduce the risk of unintentional kinking and further damage to the sealing membrane.
  • a rail for holding down a roofing membrane hereinafter also called retaining rail to create, which does not have the disadvantages of the known hold-down rails.
  • a lightweight and firm holding rail with increased longitudinal stiffness to be created, which path movements and thus tears, resp. Preventing wear of the sealing sheet in the region of the fastening means and ensuring a watertight welding of the cover strip with the roof covering sheet by means of a welding string.
  • a retaining rail with the features of claim 1 and in particular by a retaining rail, which has a cross-sectional profile with a central web and with lateral edge folds, wherein the web is provided with openings for the attachment of fasteners.
  • each of the lateral edge folds forms at least one support-side shoulder and the web lies above the support plane spanned by these support-side shoulders. This has the consequence that the bridge does not rest on the roof covering and even in the assembled state this not or only slightly impress.
  • This web arrangement ensures that the force exerted by the fastening means is transmitted to the support rail from the web to the edge folds and is not limited to the center.
  • the support surface is reduced compared to conventional support rails and thus increases the contact pressure in the region of this support surface.
  • the multiple folding leads to increased longitudinal stiffness and thus allows to reduce the number of required fasteners and the material thickness of the retaining rail.
  • each of the lateral edge folds forms a plurality of support-side shoulders.
  • this multiple folding leads to increased longitudinal rigidity and thus allows the number of fastening means required as well as the material thickness of the retaining rail to be further reduced.
