Definitions

  • the invention relates to a cover for a building according to the preamble of claim 1.
  • thermoplastics made of steel professional sheet (trapezoidal sheets) with insulating materials made of thermoplastic plastic arranged thereon are known. In the event of a fire, these thermoplastics sinter or melt and thereby absorb heat. The thermal energy acting on the steel profile sheet can thus be dissipated over a certain period of time and the thermal load on the steel profile sheet can be reduced.
  • the thermoplastic usually does not itself have any fire-retardant properties. In addition, harmful decomposition products can be expected in the event of a prolonged fire.
  • the fire retardant substance has two functions. On the one hand, the trapezoidal sheet is protected against overheating and thus a reduction in the load-bearing capacity. On the other hand, the fire prevents the insulation materials etc. on the steel profile sheet from attacking. Water is used in particular as a fire-retardant substance, which is inexpensive and is usually also available where the building roof or wall covering is used. There are therefore no further transport costs. In addition, water is not only fire-retardant due to its relatively high heat absorption during the transition from the liquid to the gaseous phase, it is also known to be suitable as an extinguishing agent.
  • the fire-retardant substance is advantageously arranged in elongated hollow bodies which are inserted into the channels and completely or partially fill the cross section thereof.
  • the fire-retardant substance can be placed precisely at the desired location, which is particularly necessary in the case of channels which are inclined with respect to the horizontal.
  • the choice of the material for the hollow body can also control the release of the fire-retardant substance as a function of the temperature by selecting the choice of the hollow body material as a function of the temperature at which the fire-retardant substance melts through the most heated point Wall of the hollow body is released.
  • the hollow bodies can consist of containers which have a preferably trapezoidal cross section corresponding to the channels.
  • the hollow bodies can consist of hoses of different, preferably round, cross sections.
  • other designs of the hollow body that are favorable in terms of production technology are also conceivable.
  • each channel is assigned hollow bodies with separate cavities one behind the other for receiving the fire-retardant substance.
  • the separate cavities of each channel are expediently formed by assigning several hollow bodies lying one behind the other.
  • the spaces between the hollow bodies, which are spaced one behind the other, are sealed off (liquid-tight).
  • This design has the advantage that when the cover is partially heated, only the hollow body or bodies melt in the area of the source of the fire to release fire-retardant substance.
  • the (liquid-tight) partitioning prevents the fire-retardant substance from being sealed off in a less endangered area of the cover, particularly where the cover is inclined to the horizontal, in which the effect of this substance is not required.
  • a plurality of separate cavities, which are spaced one behind the other, is expediently partitioned off by means of a spray foam, in particular a PU foam.
  • the partition can be easily applied after the hollow bodies have been inserted into the channels, adjacent hollow bodies simultaneously serving as (lost) formwork.
  • an insulating and insulating layer to be arranged on the base layer can also be produced by spraying on a foam, for example a multi-component PU foam.
  • a foam for example a multi-component PU foam.
  • Such an insulating and insulating layer is simple and inexpensive to apply, while at the same time the hollow bodies are locked in the channels in the correct position.
  • Such insulation and insulating layer has the advantage that produced by these at the same time A obligations bschot- hinterchaneau.len between hollow bodies in the grooves beyond.
  • the hollow body is formed from thin tubes r each channel is assigned a single hose that runs continuously over the entire length of the same.
  • the ends of the hoses are each connected to a common reservoir for the fire-retardant substance on opposite end faces of the base layer, in which the channels open.
  • the reservoir can be formed from a container, in particular a water container, assigned to each of the two opposite end faces of the base layer.
  • a heat-resistant (metal) line which can be fed for the fire-retardant substance, preferably an existing water supply network.
  • the embodiments of the invention shown relate to a roof covering 10 made of several layers.
  • the roof covering 10 is composed (from bottom to top) of a base layer 11, a vapor barrier 12, an insulation layer 13 and three sealing sheets 14, 15 and 16.
  • the support layer 11 is made of sheet steel, namely as a trapezoidal sheet and has channels 18 formed parallel to one another and formed by its trapezoidal profile.
  • the channels 18 are open at the top, that is to say toward the vapor barrier 12.
  • the roof covering 10 shown in Fig. 1 are in the grooves 18 each elongated, the cross-section of the grooves 18 filling hollow body, namely container 19.
  • the outer contours of the container 19 are adapted to the inner dimensions of the channels 18, and provided with a trapezoidal cross section, the vapor barrier 12 coming to rest on the upper transverse plates 20 of the base layer 11.
  • Fig. 3 shows a hollow body, which is designed as the groove 18 insertable hose 29.
  • the cross section of the hose 29 results from the fact that it is inserted into the trapezoidal profile 17.
  • the wall 22 of the hollow body 19 designed as a hose is flexible.
  • the hoses 29 are provided with fillers 23 for filling with a fire-retardant liquid.
  • the filler neck 23 is firmly connected to the wall 22 of the hose 29, in particular welded.
  • the support layer 11 is provided in the region of its lower transverse plate 24 with a passage 25 for receiving the filler neck 23.
  • the passage 25 is drawn in dashed lines in FIG. 4.
  • the former is provided with an external thread 26 and a matching nut 27.
  • the nut 27 ensures that the filler neck 23 cannot be pulled out of the lower transverse plate 24.
  • the containers 29 can also be provided with a filler neck.
  • FIG. 5 shows an embodiment in which several, namely three hoses 28 are inserted into the groove 18 of the base layer 11.
  • the advantage here is that the tubes 28 are smaller and thus easier to handle or can be manufactured in larger numbers. This makes it possible for different Dimensions of the trapezoidal profile 17 always use the same hoses 28.
  • each channel (18) of the base layer 11 is assigned a plurality of hollow bodies one behind the other, namely containers 30.
  • the containers 30 are of considerably shorter design, but are otherwise of the same shape.
  • the containers 30 lie one behind the other in each of the troughs 18, which creates a space between adjacent containers 30, which is filled by a corresponding partition 31.
  • the partition 31 can be made of a molded foam (PU foam) so that it is almost waterproof.
  • PU foam molded foam
  • FIG. 7 shows containers 32 which do not completely fill the cross section of the channels 18, namely have a lower height than the channel 18.
  • the containers 32 designed in this way absorb a smaller volume of fire-retardant liquid due to the reduced cross-section.
  • the weight load on the roof covering 10 is reduced in this way, which may be necessary in some cases.
  • FIG. 7 a simplified insulating and insulating layer is shown in FIG. 7. This consists of a homogeneous foam layer 34 which can be easily sprayed onto the support layer 11 and the containers 32 arranged in the grooves 18 thereof. Likewise, the foam layer 34 can serve to form the partition 31 between the containers 30.
  • the foam layer 34 is preferably made of a multi-component PU foam plastic.
  • FIG. 8 shows an embodiment of the invention, in which the hollow bodies are formed from relatively thin tubes 35, each of which has a tube 35 running through one of the channels 18. Since the tubes 35 can only hold a relatively small volume of fire-retardant liquid, the opposite ends thereof are connected to liquid reservoirs 36.
  • the two opposite end faces 36 of the support layer 11, in which the channels 18 open, are each assigned a liquid reservoir in the form of a storage container. In each storage container 37 all hoses 35 protrude from an end face 36 from the support layer 11.
  • This design has the advantage that the relatively thin hoses 35 with the small amount of liquid contained in the roof cover 10 weigh so little, but on the other hand by appropriate dimensions of the Storage container 37 a sufficiently large amount of liquid is available in the event of a fire.
  • FIG. 9 shows an embodiment of the invention, in which a thin tube 35 is also arranged in each channel 18.
  • the hoses 35 are only supplied in a different way, namely by means of highly heat-resistant (metallic) lines 38.
  • each end face 36 is in turn assigned a line 38 which has connections 39 for the ends of the hoses 35.
  • the lines 38 are supplied by a central liquid reservoir.
  • the line 38 or the lines 38 are expediently arranged in an edge region of the roof, where leaks, on the one hand, cannot lead to the roof not being impaired and, on the other hand, a check of the connections 39 can be carried out easily.
  • Water is advantageously contained in the hollow bodies as a fire-retardant substance, both when used for a roof covering and for a wall covering. This is particularly suitable in the embodiment of FIG. 9 as a fire-retardant substance, since then the lines 38 need only be connected to the existing water supply network.
  • the wall covering 33 thus has a sandwich-like structure.
  • the walls 22 of the hollow body consist of a gas-tight material, in particular of thermoplastic material, for example polyethylene. It is also conceivable to produce the walls 22 of the hollow body from metal-coated foils or from foil laminates. The materials mentioned ensure that the fire-retardant substance, in particular water, can be safely stored in the hollow bodies without significant losses.
  • the downwardly open channels 18 of the base layer 11 with hollow bodies which contain a fire-retardant substance (water).
  • a fire-retardant substance water
  • one or more containers with the fire-retardant substance can be attached under the base layer.
