Definitions

  • the invention relates to a roof structure, in particular for flat or flat-pitched roofs, with a substructure and on this loosely laid roof skin made of elastic sealing sheets, optionally with intermediate layers such as thermal insulation layer, protective layer, vapor barrier layer, etc., the roof skin being kept at the edge of the substructure.
  • the wind suction forces arise from an increased wind speed on the roof surface. These are generated by vortex formation, e.g. Bag swirls reinforced in the edge and corner area of the roof area. This creates a vacuum on the roof structure.
  • DE-AS 23 17 545 already describes a device for changing the wind flow conditions on sloping or slightly inclined roofs, with the help of which the vortex formation and thus the resulting wind suction forces are weakened, so as to reduce the load on flat roof constructions.
  • interfering elements are arranged in the area of the roof corners of the roof structure, which reduce the formation of eddies in the edge and corner areas and thus the risk of lifting the roof structure and the. Reduce wind suction loads.
  • the invention has for its object to provide a roof structure with loosely laid roof skin without load and without surface fixation, which still withstands the wind suction.
  • the type of construction of the roof seal according to the invention for loosely laid roof skin when the roof surface is exposed to wind is based on preventing the air pressure compensation between the loose roof skin (roof seal) and the substructure.
  • the thermal insulation layer, the roof skin When considering the roof waterproofing with loose installation as a multi-layer package with a supporting substructure, the thermal insulation layer, the roof skin, it becomes clear that there is an atmospheric air pressure in the layers that creates the roof skin under negative pressure above the roof surface, e.g. by wind suction forces, pushes up.
  • the space in the multi-layer package increases until the same pressure - negative pressure - as arises on the outside surface of the roof skin.
  • the solution according to the invention prevents pressure equalization in the multi-layer package or between the roof skin and the substructure.
  • the seals according to the invention are provided in the area of the roof edge and the roof penetrations and by a tight substructure in the area of the entire roof area.
  • thermoplastic or elastomeric or thermoplastic-elastomeric plastic sealing sheets based on soft PVC, polyisobutylene, butyl rubber, polychloroprene, chlorosulfonated polyethylene, ethylene-propylene-ter-polymer rubber with or without fabric reinforcement.
  • the substructure as a so-called second membrane is to be designed with sufficient rigidity and static strength to absorb the wind suction forces without compliance.
  • the substructure can, for example, of a solid concrete ceiling, a concrete or lightweight concrete prefabricated ceiling with grouted joints, a roof seal already fully glued to a surface, e.g. B. on a bituminous basis with good adhesion to the substrate, trapezoidal sheet roofs, old bitumen roofs, or one made of chipboard with sealed joints. Roof area exist.
  • this skin is not only to be fastened to the edge of the roof, but also to be sealed.
  • the roof skin is mechanically sealed in the area of the edge of the substructure
  • Application of pressure by means of sealing tapes, sealing compounds, etc. and / or by means of source welding, by means of adhesion promoters, adhesive tapes or the like is stored.
  • the means to be used for the seal also depend on the materials used for the roof skin, for example, when using soft PVC sealing sheets, swelling can often be carried out to make connection materials, while, for example, when using EPDM-based sealing sheets with adhesive tapes or appropriate adhesion promoter is sealed.
  • Another advantageous embodiment of the invention provides that in order to reduce the air pressure in the space between the roof skin and the substructure, air is drawn off when the roof seal is created. In this way, the space between the roof skin and the substructure can be kept as small as possible from the outset and, at the same time, the roof skin, which is loosely laid, can lie flat on the roof surface.
  • FIG. 9 shows the basic structure and the mode of operation of the roof structure according to the invention.
  • the roof skin 6 On the mechanically stiff and statically sufficient to accommodate wind suction forces and sealed against air supply, the roof skin 6 is placed on an elastic plastic sealing membrane and sealed in the edge area 37 firmly connected to the substructure 1.
  • the intermediate space 36 is located between the substructure 1 and the roof skin 6.
  • the wind flowing in the direction of the arrow 38 generates underpressure by wind suction forces in the edge region as a result of eddy formation due to increased wind speed on the roof surface when flowing in the arrow direction 39 in the region 40 above the roof skin 6.
  • FIG. 1 shows, for example, the edge formation of a roof structure with a loosely laid roof skin.
  • the substructure for example a cast concrete ceiling, is formed in the roof edge area with the raised edge 1 a.
  • This substructure 1 is sealed by a multi-layer roof seal.
  • a loosely laid protective layer lies directly on the substructure, for example a polyethylene film is a thermal insulation layer 4, for example made of polystyrene foam panels, which is loosely placed on its edges.
  • the thermal barrier coating can also be made from other foams, for example from phenolic resin foams, polyurethane foams, polyethylene foams, cross-linked polyethylene foams be posed.
  • the outer finish forms the roof skin 6 from elastic stretchable roof sealing sheets that are tightly connected at their seams, for example made of soft PVC. The sealing of the air space remaining between the roof skin 6 and the substructure between the individual layers and the attachment of the layers to the substructure are carried out with the following means.
  • the vapor barrier film 3 is pulled up over the upstanding edge 1 a of the substructure and is sealed off from the substructure with the sealing tape 9 and to the outside with the sealing tape 10, for example from a closed-cell soft foam.
  • the layers are fixed in the edge area by means of wooden planks 8, which rest on the vapor barrier film 3 and are fastened to the substructure 1 by means of screws and dowels and at the same time press the sealing tape 9.
  • the thickness of the wooden plank 8 corresponds to that of the thermal insulation layer 4.
  • an angled plastic composite sheet profile 18 is fastened by means of nails 19 with the interposition of a further sealing tape 11, the side of the profile 18 coated with plastic being used for tight welding of the roof skin 6.
  • the plastic coating of the profile 18 also consists of soft PVC, so that swelling can be carried out in the area 15 in a simple manner.
  • the upstanding edge 1 a of the substructure is also sealed with the additional heat insulation layer 16 and the loose protective layer 17, the outer edge is formed by the plastic composite sheet profile 12, which is fastened by means of nails 14 to the edge 1 a with the interposition of the sealing tape 10 and its plastic-coated Top side for welding the strip 13 from the sealing sheet in addition to the roof skin 6 to form the sweat weld seam 15 serves.
  • the strip 13 bridges the edge area from the profile 12 to the profile 18, to which it is also welded with its other end and thereby creates the seamless, tight transition to the roof skin 6. While the plastic composite sheet profiles 12, 18 produce the mechanical fixation of the roof skin and the roof structure to the substructure 1, the sweat weld seams 15 and the sealing tapes 9, 10, 11 are used to seal the space 36 between the substructure 1 and roof skin 6.
