Definitions

  • the present invention relates to a device for fastening fabric-like material for the construction industry, in particular fire protection material, with a fastening means made of flexible material that can be carried out through the fabric-like material.
  • fabric-like materials for the building industry are known, for example in the form of wire mesh, glass fiber or textile fibers, which are used as a barrier or reinforcement.
  • fabric-like fire protection materials are known which are provided with an intumescent coating, so that the intumescent substance foams when exposed to heat, which fills the interstices of the mesh fabric, for example, and thus counteracts the passage of heat and combustion air.
  • fabric mats are able to prevent the fire from spreading for 30 to 120 minutes (cf. DE 30 111 453 A1 and US P 42 55 483).
  • These fire protection mats are manufactured as an endless belt, but are cut into smaller sections for transport and handling. When laying on the wall, such a section is stapled on both sides to such an extent that the intermediate part of the section formed by a corresponding oversize protrudes from the wall and thus forms an insulating pocket.
  • connection joint arises when a section of material is to be wrapped around a cable, a pipe, a cable duct or a cable route.
  • the usual fastening of the sections known from practice is realized by means of a well flexible wire, for example an iron wire (Rödei wire) softened by annealing.
  • the wire is pulled through both fabric joints and the two wire ends are twisted together to secure the fabric joints.
  • the known fastener is in view of the considerable work involved in pulling through and Twisting and the cumbersome handling disadvantageous, especially when larger connection areas must be closed.
  • the present invention has for its object to provide a device of the type in question, which enables a simple and effective connection of fabric-like materials, in particular fire protection materials.
  • the use of the device in power plant construction is to be made possible.
  • the device in question is characterized in that at least two fastening means are arranged on a base plate.
  • a base plate is now proposed on which at least two fastening means are arranged.
  • the handling of the device according to the invention can be carried out with respect to the butt-to-butt connection of Material sections are carried out in such a way that the fastening means is passed from below through the fabric joint of the first material section or the fabric joint of the first material section is pushed onto the fastening device and then the fastening device is bent over to fix the section h the first section is captivated. After the first section is fastened, the fabric joint of the second section is pushed onto the second fastener and then also fixed by bending the fastener.
  • the fixing of the second section is not hindered by the first, already fixed section, since the fastening means for the first section extends parallel to the base plate in the fixing position and the tissue joint presses against the base plate. Can continue the device according to the invention can of course also be handled so that the sections overlap.
  • a particularly simple pushing of the fabric-like material onto the fastening means or a particularly simple passage of the fastening means through the material can be achieved if the fastening means protrude from the base plate. If the fastening means extend orthogonally to the base plate, the base plate and the respective material section can be brought parallel to one another in an advantageous position that is easy to produce, before the fastening process takes place.
  • fastening means are spaced apart from one another, to be precise in accordance with the mesh spacing of the tissue-like material to be fixed. This makes it easier to push the fasteners through the material.
  • One of the fastening means is preferably designed to be somewhat longer in order to serve as the first guide.
  • the fastening means could also consist of toboggan or aluminum wire. Copper or brass wire is also conceivable. In any case, the wire must have sufficient rigidity on the one hand to allow the fabric-like material to be pushed on and on the other hand can be bent easily and without great force and hold the device in the material in this bent position.
  • the fastening means made of wire could be in the form of an endless wire which is arranged below the base plate or between two layers of the base plate and is looped through openings in the base plate or in the upper layer of the base plate.
  • the two layers of the base plate could be obtained by bending a sheet-like starting material to fix the continuous wire.
  • the wire loops protruding through the openings could also be jammed in the openings from the rear or else soldered.
  • the fastening means could also be formed from wire sections which are soldered onto the base plate.
  • the fastening means could be made of sheet metal, in particular iron or aluminum, and preferably narrow and conical towards the free end, so that the penetration of the fabric-like material is facilitated.
  • the fasteners made of sheet metal could also be welded or soldered onto the base plate.
  • the fastening means could also be punched out of the base plate, milled out or cut out by laser.
  • the punched out, milled or laser-cut fasteners are first bent so that they protrude from the base plate and can be passed through the material.

  • the embodiment in question of the device according to the invention offers the advantage that the bending-up takes place only when it is used and therefore the devices can be packed more tightly.
  • the use of a band-shaped starting material for the base plate and thus continuous production with a predeterminable length and number of fasteners is possible.
