13: The method according to claim 12, wherein the connection is established at every of the edge length c so as to have at least two fastening points per side.

14: A method for solving universal fire protection for a tested and/or approved wooden wall and/or wooden ceiling construction in buildings, comprising: installing the feedthrough module according to claim 1.

Description

[0028] The invention is explained in greater detail by the following example in conjunction with the accompanying figures, in which:

[0029] FIG. 1 is a perspective view of a feedthrough module according to the invention, and

[0030] FIG. 2 is a perspective view of a feedthrough module according to the invention when installed in a wooden wall construction.

[0031] FIG. 1 shows an embodiment of the feedthrough module of the present invention. The feedthrough module 1 has a cuboid body having edge lengths a, b, c, wherein c is the edge length corresponding to the installation thickness (D). The feedthrough K for cables, cable bundles, cable trays, pipes, pipelines, empty pipes and/or combinations thereof that are to be fed through is positioned and mounted at a minimum distance (f) of approximately 50 mm away from the outer edges of the cuboid body.

[0032] In FIG. 2, the feedthrough module 1 is installed in a wooden wall construction 2. The reference signs are the same as for FIG. 1.

[0033] Classification test of the feedthrough module: A fire protection sleeve, such as CFS-SL from Hilti ( 113 mm), having A and B cables (cable outer diameter 21 mm) is installed ( 120 component opening having annular gap sealing material, for example fire protection sealing compound CFS-S ACR from Hilti) in a feedthrough module, also known as a block, which is made of cross-laminated timber and has the thickness of d=148 mm (installation thickness (D) equal to edge length c). These have a fire resistance class, according to EN 13501-2, of EI 90. The approved wooden wall element to be penetrated also has a fire resistance class of EI 90 (Leno cross-laminated timber type ETA-10/0241). The feedthrough module has a side edge length ab of 300300 mm. The feedthrough module is fastened in the surrounding wooden wall element by means of a concealed screw connection at every of c so as to have two fastening points per side. Classification tests according to EN 13501-2:2016 have shown that the feedthrough module installed by means of concealed screw connections also achieves a fire resistance class of EI 90 in the overall component. These demonstrate that the module can be universally used as a fire protection solution in various tested and/or approved wooden wall and/or wooden ceiling constructions.

[0034] It has been shown that the feedthrough module of the present invention produces a predetermined fire protection performance and can therefore be universally used as a fire protection solution in various tested and/or approved wooden wall and/or wooden ceiling constructions. The feedthrough module is suitable for cables, cable bundles, cable trays, pipes, pipelines, empty pipes and/or combinations thereof. Another advantage shown is that the use of non-wood-like material such as dry construction materials, mineral materials and metal materials can be dispensed with on installation surfaces. Water and moisture is prevented from penetrating into a wooden wall and/or wooden ceiling construction. Ultimately, it has been shown that the feedthrough module of the present invention allows flexible dimensioning of the feedthrough surface.

[0035] It has also been shown that the feedthrough module for cables, cable bundles, cable trays, pipes, pipelines, empty pipes and/or combinations thereof that consists of hardwood, softwood or mixtures thereof represents a universal fire protection solution for a tested and/or approved wooden wall and/or wooden ceiling construction in buildings. In particular, it has been shown that the feedthrough module is a fire protection solution for a tested and/or approved wooden wall and/or wooden ceiling construction in buildings, wherein the tested and/or approved wooden wall and/or wooden ceiling construction has an equal or lower burn rate than the feedthrough module, wherein the feedthrough module has a cuboid body having edge lengths a, b, c, wherein c represents the edge length corresponding to the installation thickness (D) of the feedthrough module, and wherein the feedthrough module has a nominal burn rate of 0.7 mm/min or less.
