Definitions

  • the invention relates to an attachment
  • Roof waterproofing membrane or the like consisting of a support element and a fastening means penetrating this and the underlying sealing membrane, the upper end of which is pivotally and forcefully connected to the support element and the lower end of which is anchored in the substructure.
  • Sealing membranes in particular sealing membranes made of PoLyi sobutene, Po Lyvi ny L ch Lori d, bitumen, PoLymerbi gymnastics or the like, laid on a flat roof, are to be fixed to the subsurface using mechanical fastenings to prevent lifting. At least three, in the corner area up to more than ten and in the edge area an intermediate number of fastenings per square meter roof area must be provided in order to prevent this being lifted off by wind.
  • the fastenings are arranged in the edge area of the roof waterproofing membrane and covered by the adjacent roof waterproofing membrane, a seam overlap of 10 cm to 12 cm being provided. Seam overlaps represent a significant cost factor, especially for plastic roof waterproofing membranes.
  • fastenings within an area are to be distributed approximately equally over the roof area, in areas that require a large number of fastenings, narrower roof sealing sheets are laid as in the central area of a roof.
  • the fastenings are therefore arranged in rows running parallel to the edges of a roof waterproofing membrane.
  • the spacing of the fastenings can be adjusted within a range of the number of fastenings required per square meter. there A distance of more than 50 cm as well as a distance of less than 15 cm should be avoided.
  • the dependency on different web widths also means a relatively complex design in practice.
  • Load introduction is mechanically unfavorable when the roof membrane is mechanically fastened in the covered edge area, since the load is implemented asymmetrically and therefore considerable safety requirements are required.
  • a fastening of a roof sealing membrane is known from US Pat. No. 4,860,513, which contains a disc-shaped support element resting thereon with a centrally arranged passage opening.
  • the wall of the through opening is designed to have a spherical shape toward the top, in order to receive a screw shaped head on the underside of a screw serving as a fastening means, through which the sealing membrane penetrates.
  • the head of the screw is provided with a hexagon socket on its top. Due to the spherical shape of the screw head in the support element, the screw can be swiveled in relation to the level of the support element. However, the top of the head of the screw is exposed to the weather, so that if the screw connection is loosened, water can penetrate under the sealing membrane.
  • Support element overlaps and rests with its outer edge on the roof waterproofing membrane.
  • the screw is guided in the hollow of the shaft in the direction of the center salmon of the support element.
  • the object of the present invention is to provide a fastening of the type specified at the outset in such a way that it provides a reliable seal for the fastening part, even when the fastening is not exactly perpendicular to the roof surface

Abstract

Une fixation (10) de bande (18) d'étanchéité de toit ou similaire comprend un élément de support (14; 114) et un organe de fixation (16) qui traverse l'élément de support (14; 114) et la bande d'étanchéité sous-jacente (18). L'extrémité supérieure de l'organe de fixation (16) est reliée pivotable par liaison de force avec l'élément de support (14; 114) et son extrémité inférieure est ancrée dans la charpente (22). Afin d'obtenir une fixation qui assure une étanchéité fiable du point de fixation même lorsque l'organe de fixation n'est pas orienté avec précision perpendiculairement à la surface du toit, l'élément de support (14; 114) est réglable en hauteur à l'intérieur d'un élément de couverture (12; 112) convexe posé sur la bande d'étanchéité (18) et dont la face inférieure est fermée par une plaque de fond (44; 144). La partie périphérique (40; 140) de l'élément de support (14; 114) est en prise avec la paroi intérieure (42; 142) de l'élément de couverture (12; 112), de sorte que l'élément de support soit relié à l'élément de couverture (12; 112) de manière à pouvoir tourner avec celui-ci au moins dans ses positions extrêmes supérieure ou inférieure. La liaison pivotante par liaison de force de l'extrémité supérieure (26) de l'organe de fixation (16) qui traverse la plaque de fond (44; 144) avec l'élément de support (14; 114) est assurée par un corps articulé (15) monté de manière à pouvoir pivoter mais non tourner dans la partie supérieure de l'élément de support (14; 114). Le corps articulé (15) est relié à l'extrémité supérieure de l'organe de fixation (16) de manière à tourner avec celle-ci. Un récipient (50; 150) rempli d'une masse d'étanchéité (52; 152) et s'ouvrant dans ses positions extrêmes supérieure ou inférieure lorsque l'élément de support (14; 114) s'approche, laissant sortir la masse d'étanchéité (52; 152), peut être situé à l'intérieur de l'élément de couverture (12; 112).
