Definitions
- the present invention relates to a fireproof material for protecting conduits such as cable channels or pipes in case of fire.
- Fireproof material of the type mentioned above is used, e.g., in the form of pipe sections, matting, or as strips for shielding conduits such as cables conduits, cable routes, insulated steel pipes, plastic pipes, etc., to squeeze and to completely cut off the latter in case of fire.
- conduits such as cables conduits, cable routes, insulated steel pipes, plastic pipes, etc.
- the cables, conduits, routes, etc. mentioned above are lined or covered in a ring-shaped manner by the fireproof material in the area of a wall lead through.
- WO 99/18303 A1 discloses a method of protecting from fire of pipes and cable conduits from fire according to which various fireproof materials are arranged in layers around pipes or cable conduits in the area where they pass through a wall. For example, a strip-shaped intumescent material is placed around a pipe conduit initially and a layer of a material that shrinks when acted upon by heat is then arranged around this layer. In the event of fire, this layer of the shrinkable material contracts when heated and reinforces the squeezing of the pipe by the intumescent compound.
- a fireproof material having a matrix of plastic material which can shrink when acted upon by heat and in which inclusions of an active fireproof material are embedded.
- the shrinkable plastic materials are, e.g., polyolefins, fluoropolymers and elastomers whose molecules are crosslinked, e.g., by radiation polymerization, while as the active fireproof material, e.g., an intumescent, ceramizing or ablative material can be used.
- This step provides a homogeneous fireproof material which can be arranged at a conduit in only one work step and can be sealingly shrunk over this conduit by heating.
- the fireproof material can be produced by a continuous method, e.g., as strip goods.
- This strip-shaped fireproof material can then be wrapped around conduits and subsequently sealingly shrunk thereon.
- inclusions can also be shaped in any other manner, e.g., be made spherical, granular, or rod-shaped.
- the fireproof material can advantageously be tubular. In this way, it can be pulled directly over a conduit and then shrunk onto it.
- An adhesive layer can be advantageously applied to a flat side of a strip-shaped fireproof material, and the fireproof material can be preliminary fixed on a conduit by the adhesive layer prior to shrinking.
- the fireproof material can advantageously also be formed as a ductile or kneadable mass. This mass can be used in a flexible manner also for conduit lead-throughs that are difficult to access and can be pressed into very narrow gaps. By a subsequent heating, the kneadable fireproof material can then be sealingly shrunk over the cable.
- FIG. 1 is a cross-sectional view of a ring-shaped fireproof material according to the present invention, arranged around a conduit;
- FIG. 2 shows a view similar to that of FIG. 1 with the fireproof being shrunk on the conduit;
- FIG. 3 shows a cross-sectional view of a strip-shaped fireproof material according to the invention
- FIG. 4 shows a cross-sectional view of the strip-shaped fireproof material along line IV-IV from FIG. 3 ;
- FIG. 5 shows a cross-sectional view of a fireproof material in the form of a kneadable mass.
- FIG. 1 shows a fireproof material 10 in the form of a tubular section which, in this case, is arranged around a conduit 20 and is formed as a pipe.
- the fireproof material 10 has a matrix 11 of a plastic material that is shrinkable under the influence of heat.
- Shrinkable plastic materials of this kind are, for example, polyolefins, fluoropolymers, and elastomers whose molecules are crosslinked, e.g., by radiation polymerization.
- Inclusions 12 of an active fireproof material e.g., an intumescent, ceramizing or. ablative material, are incorporated in the matrix.
- inclusions 12 can be, e.g., granular, spherical, rod-shaped, strand-shaped, fibrous, or the like.
- the dimensions of the inclusions 12 can range from a fine dispersion (the size of dust particles) to one or more millimeters. In the case of strand-shaped or fibrous inclusions 12 , their length corresponds approximately to the axial length of the tubular fireproof material 10 .
- the tubular portion of fireproof material 10 is shrunk on the conduit 20 by a local heat treatment (e.g., heating to approximately 70° C.).
- the material of the matrix 11 is shrunk by the heat treatment to approximately 70%-25% of its original dimensions so that the fireproof material now tightly contacts the surface 21 of the conduit 20 .
- the inclusions e.g., of an intumescent material, swell and squeezes the conduit 20 . This prevents the spread of fire.
- the fireproof material 10 is formed as strip-shaped flat material.
- the matrix 11 is again formed of a plastic material which is shrinkable under the influence of heat and in which are incorporated inclusions 12 of active fireproof material, described above.
- An adhesive layer 13 is arranged at a flat side 14 of the fireproof material 10 .
- the fireproof material 10 can be fixed at least in a preliminary manner to a conduit by this adhesive layer 13 .
- the inclusions 12 are strand-shaped in this case and extend approximately parallel to the longitudinal extension of the fireproof material 10 . In the mounted position of the fireproof material 10 , the latter compasses a line 20 analogous to FIG. 2 .
- the fireproof material 10 can also be formed as a kneadable or deformable mass and has a matrix 11 of a plastic material which is shrinkable when acted upon by heat and which is also elastically deformable. Inclusions 12 of an active fireproof material are again arranged in this matrix 11 as was already described above.
- the mass according to FIG. 5 can be used in a very flexible manner and can also be applied in very narrow structural spaces.
