Definitions

  • the invention relates to a fastening element for fastening facades, preferably for fastening thermal insulation composite systems, consisting of a support plate and a sleeve for receiving a dowel with an expansion element.
  • the carrier plate has a lowering in the form of a sleeve in the center, to which an opening for receiving the dowel is attached at the lower end.
  • the dowel is attached to the outer wall with the help of an expansion element.
  • the depth of the depression corresponds at least to the head height of the expansion element consisting of shaft and head and the diameter of the opening corresponds at least to the shaft diameter of the expansion element.
  • force-absorbing fastening elements are attached to the outside of the thermal insulation elements - 2 -
  • the necessary holding forces are transferred from the thermal insulation element to the load-bearing wall.
  • Known systems use plates for these fastening elements, which lie against the outside of the thermal insulation element and are fastened in the masonry or in the wall with the aid of dowel shafts and expansion elements.
  • the carrier plate is usually made in one piece with the dowel shaft.
  • Multi-part elements are also known, in which on the one hand the carrier plate is produced with an integrally formed sleeve, into which the plug shaft is inserted together with a screw during assembly, and on the other hand the carrier plate and sleeve are produced separately from one another and are inserted into one another for assembly.
  • Insulation fasteners consist of a plastic part and a set bolt.
  • the plastic part consists of the carrier plate, the sleeve and self-sleeve-shaped spring element arranged in the sleeve or at the foot of the sleeve.
  • the element is connected to the load-bearing wall by means of set bolts which are driven pyrotechnically into the ground.
  • the carrier plates used must have sufficient strength and rigidity to withstand the stresses caused by wind forces and the static loads on the plaster or Mortar layer of the composite system occur, can be safely absorbed.
  • the fastening elements known in the prior art are provided with relatively small, disk-shaped carrier plates which, viewed from the outside of the finished insulation layer, are flat or convex and can be provided with stiffeners. These designs can lead to an undesirable increase in the thickness of the carrier plate. However, certain values for the thickness of the carrier plate must not be exceeded in order to prevent the fastening element from protruding through the plaster layer or from the plaster layer not having a sufficient thickness in the region of the fastening elements.
  • the invention has for its object to improve a fastener of the type described above so that both simple manufacture and assembly and a secure hold of the facade system is achieved with a small number of fasteners and largely forces in the fastener and in the connection to the ground be avoided.
  • the object is achieved in that the carrier plate consists of a flat network which is provided on its underside with spacer elements and the lowering of the carrier plate is connected to the network by an at least partially made of flexible elements sleeve, the sleeve at the lower end turns into a ring.
  • the network-like carrier plate merges into an at least partially in webs, rods, ribs or in a sleeve dissolved in a network, which penetrates the insulation material at right angles or at an acute angle to the wall and passes into a ring near the supporting wall, so that the forces can be introduced in a dowel or comparable fastening element.
  • the sleeve can also pass directly into the dowel shaft and be anchored in the subsurface using the expansion element. Furthermore, it is possible to guide the sleeve, which is broken up into individual rods or into a network, into the ground and anchor there by means of an expansion element or mortar injection.
  • Preferred configurations of the carrier plate are in the form of a rectangle with an edge length of 60 to 200 mm, circular or elliptical in shape with an outer diameter of 60 to 200 mm or with a polygonally shaped outline. It is also possible that the carrier plate is reinforced by ribs which are made from the edge to the center with increasing width and / or height.
  • the carrier plate, extension or sleeve are produced separately from one another and shaped in such a way that they can be fitted into one another in a fitting manner or that the carrier plate and sleeve have an annular step fold for fitting into one another.
  • the sleeve can be designed like a net or rod and can be hooked onto the carrier plate with these rods or nets.
  • the sleeve which is broken up into rods or into a net, can be inserted into a borehole in the subsurface and anchored there by means of a spreading element and / or mortar injection. It can also be attached to the base using a set bolt and, if necessary, the associated plastic sleeve.
  • the net-like or grid-like structure of the carrier plate is supplemented by a disk-like ring, so that the overall load-bearing capacity results from fastening the insulation plate and from the bond between the fastening element and the clothing material.
  • the fastening element according to the invention has a number of advantages. It is particularly advantageous that the fastening forces are transferred directly from the clothing (plaster and the like) to the masonry without taking the detour via the insulating element, because the spacer elements in the carrier plate and the network-like structure of the carrier plate form-fit the carrier plate components are surrounded by mortar. Furthermore, the sleeve can be moved or displaced by the dissolution into individual elements, so that temperature-related deformations can be absorbed with little force.
  • the expansion element which is generally a screw, is therefore only subjected to tension or pulling. As a result, statically determined conditions are achieved, which enables the screw dimensions to be reduced and thus contributes to reducing the thermal bridges.

Abstract

L'invention a pour objet d'améliorer un élément de fixation du type décrit de telle manière qu'il puisse être produit et monté facilement et assurer un maintien sûr du système façade avec un petit nombre d'éléments de fixation ainsi qu'à éviter largement les forces de contrainte générées dans les éléments de fixation et dans la liaison au terrain de fondation. Pour ce faire, la plaque support (1) est composée d'un réseau (4) couvrant toute la surface et doté sur sa face inférieure d'écarteurs. De plus, la dépression dans la plaque de base (1) est reliée au réseau (4) par une douille (2). Cette douille est constituée au moins partiellement d'éléments flexibles et se termine à son extrémité inférieure par un anneau (6). L'invention concerne un élément de fixation destiné à des façades, de préférence, à des systèmes mixtes calorifuges, cet élément étant constitué d'une plaque de base (1) et d'une douille (2) destinée à recevoir une cheville dotée d'un élément extensible.
