Definitions

  • the invention relates to a connection according to the preamble of claim 1 and a method for its production according to the preamble of claim 5.
  • Wall elements of the generic type constructed in sandwich construction are used, among other things, for the construction of cold stores and deep-freeze stores, slaughterhouses, fruit and vegetable cold stores and so-called CA warehouses, i.e. H. Controlled atmosphere warehouses.
  • CA warehouses i.e. H. Controlled atmosphere warehouses.
  • such houses must be fire-resistant. While the fire resistance of the wall elements in the area of their main surfaces is quite good, since the load-bearing inner plate and the facade plate are each made of steel-concrete, it is difficult to make a fire-resistant connection between adjacent wall elements. So far - as far as the butt joint between the facade panels is concerned - one has managed to close this butt joint with fire-resistant material such as asbestos or a concrete bar placed from the outside after connecting the wall elements. These measures are unsatisfactory.
  • the invention is therefore based on the object of providing a connection of the generic type which is simple to manufacture and is absolutely fire-resistant.
  • a method for producing the compound is to be specified.
  • the object underlying the invention is achieved in the generic connection by the characterizing features of claim 1.
  • the fire insulation board is located inside the wall elements and closes one of the boards completely by fire protection by bridging the butt joint in the area of their inner sides.
  • the space between the thermal insulation layers of adjacent wall elements is completely available for filling with thermal insulation material, so that the thermal insulation properties in the area of the joint are not impaired.
  • the measures according to the invention are preferably applied to the inside of the facade panels; but they can also be used on the corresponding inside of the supporting inner plate. If the wall elements are designed as interior wall elements, in each of which both plates are supported, the position of the refractory connection is determined according to structural aspects not directly related to the invention.
  • connection of the vapor barriers is made even easier.
  • the measures according to claim 3 serve to improve the mountability of the fire insulation board and the flue gas seal.
  • the wall elements can also be coupled on the outside of the other, not already fire-resistant, panels with a similarly constructed fire-resistant connection.
  • connection is established from the inside, i. H. the fire insulation board is installed first.
  • This work can therefore be carried out in a particularly high quality, in contrast to the subsequent plugging of asbestos or the like into the butt joint.
  • the procedural measures according to claim 6 indicate how the additional refractory connection is still made.
  • two wall elements 1, 1 ′ are arranged flush with one another in accordance with the arrangement in a wall.
  • Both wall elements are constructed in sandwich construction, i. H. they each have an inner plate serving as a load-bearing plate 2, 2 ', a two-layer thermal insulation layer 3, 3' here, a vapor barrier 4, 4 'and a plate 5, 5' serving as a facade plate.
  • the plates 2, 2 'and the plates 5, 5' are usually made of steel-concrete.
  • the heat insulation layer 3, 3 ' consists of suitable heat insulation material, usually a foamed plastic, such as foamed polystyrene.
  • the vapor barrier 4,4 ' is formed by a foil made of metal and / or plastic.
  • a heat bridge-free connection of the plates 2, 2 'with the plates 5, 5' is known from DE-OSen 2600346 and 2820920. Since the concrete from which the panels 2, 2 'and 5, 5' are made is fire-resistant, the wall elements themselves are fire-resistant when their main surfaces are exposed to fire. Problems only occur in the area of the butt joints of two adjacent wall elements 1, 1 '.
  • Each panel 5 and 5 'serving as a facade panel has an undercut 7 or 7' on its inside, ie on the side facing the vapor barrier 4 or 4 ', which recesses back from its abutting surface 6 or 6'.
  • this undercut 7 or 7 ' is a flat bar 8
  • 8' a fire-resistant material, for example a material containing calcium silicate, for example by means of screws 9 (FIG. 1 left) or by inserting it during plate manufacture (FIG. 1 right).
  • a fire insulation panel 11 for example a calcium silicate panel, is attached to these two strips 8, 8', 7 'and the butt joint 10 completely fills the space formed, namely flush with the inside 12, 12' of the plates 5, 5 ', ie flush with the vapor barriers 4,4'.
  • the attachment of the fire insulation board 11 takes place, for. B. by means of screws 13 (Fig. 1 left) or clips or gluing (Fig. 1 right) on the strips 8.
  • the vapor barriers 4, 4 ' which project beyond the abutting surfaces 6, 6' of the boards 5, 5 'can be overlapped and glued or welded together.
  • the two vapor barriers 4, 4 'can also be connected in a butt in the usual way.
  • the separated space 14 between the two-layer thermal insulation layers 3, 3 ' is filled with insulating material.
  • two insulating inserts 15, 16 are inserted, which consist of the same material as the thermal insulation layer 3, 3 '.
  • outer wall elements are connected to one another in the same way as in the exemplary embodiment according to FIG. 1. They differ from each other in that the fire-resistant connection is not attached to the facade panels, but between the load-bearing interior panels. Because of the otherwise great similarity, the same reference numerals are used for comparable parts as in the exemplary embodiment according to FIG. 1, which are followed by an " a".
  • the fire insulation panel 11a is installed through the joint 17a between the two panels 2a, 2a 'serving as facade panels and the free space 14a between the thermal insulation layers 3a, 3a', which in this case have only one layer, on the strips 8a and 8a '.
  • the free space 14a is foamed on site, since a so-called step lock, as in the exemplary embodiment according to FIG. 1, is not possible.
  • the joint 17a between the panels 2a and 2a ' is closed with a " fire seal" which consists of a fire insulation panel 18a which is arranged flush with the outer sides 19a and 19a' of the panels 2a, 2a 'serving as facade panels. It is arranged in undercuts 20a, 20a 'of the plates 2a, 2a', on the bottom of which strips 21a, 21a 'can also be attached as "counter battens".
  • the space remaining between the fire insulation board 18a and the vapor barriers 4a, 4a 'can remain hollow or can be stuffed with a mineral fiber board or the like.
  • the butt joint 10a between the supporting plates 5a, 5a 'can - as in the embodiment according to FIG. 1 - still be closed in a suitable manner, for example by means of a suitable cement.
  • the wall elements 1b, 1b ' are designed as inner wall elements, ie both plates 2b or 2b' and 5b or 5b 'are designed as load-bearing plates, between which one - in this case again two-layer - Thermal insulation layer 3b, 3b 'is arranged.
  • the vapor barrier 4b, 4b ' the respective vapor barrier can also be assigned to the other plate 2b or 2b'; vapor barriers can also be provided on both sides of the thermal insulation layer 3b, 3b '.
  • the connection between the two plates in turn corresponds to the connection according to FIG. 2.
  • the respective reference numbers are followed by a " c".
  • the fire insulation board 11, 11 a, 11 b, 11 c, 18a, 18c can each be coated with water glass in order to achieve an increased smoke gas tightness of the corresponding butt joint.
