[0018] (Overall composition) 1 and 2, the closing system 100 is a fire prevention closing system, and is provided in a penetration part X that penetrates a wall, ceiling, and floor of a structure K such as a building, and communicates with adjacent spaces (rooms) S on either side of the structure K. In this penetration part X, installed objects M, such as cables and piping, are arranged between the adjacent spaces S.

[0019] Specifically, the closure system 100 includes a first cover unit 101 and a second cover unit 102 spaced apart from each other, and a base body 103 disposed between the cover units 101 and 102 .

[0020] (Base body) As shown in Figures 3 and 4, the base body 103 has a main body plate 1 which is fixed to a structure K (see Figures 1 and 2) and has a base connecting passage 1x passing through it, a blocking plate 2 which blocks the base connecting passage 1x of the main body plate 1, and a screw fixing member 3 which removably fixes the blocking plate 2 to the main body plate 1 with a screw 20.

[0021] The main body plate 1 is fixed to the concrete surface of the structure K around the penetration portion X by, for example, anchor bolts B with its plate thickness direction aligned with the opening direction (hereinafter, penetration portion opening direction) D1 of the penetration portion X (see Figs. 1 and 2). The main body plate 1 is made of, for example, metal. A plurality of base communication passages 1x are provided, and are elongated holes extending in the plate height direction (hereinafter, simply, height direction) D3 at intervals in the plate width direction (hereinafter, simply, width direction) D2 of the main body plate 1. The object M to be installed is inserted through these base communication passages 1x. In addition, the main body plate 1 is formed with a screw insertion hole 1y extending in the height direction D3 adjacent to the base communication passage 1x in the width direction D2.

[0022] The blocking plate 2 is provided so as to abut against one surface of the main body plate 1. As shown in FIG. 5, the blocking plate 2 has a plurality of through holes 2x formed therein, which penetrate the blocking plate 2 in the plate thickness direction. The arrangement of the through holes 2x is not particularly limited, but may be, for example, a staggered arrangement. The through holes 2x may be arranged in at least a part of the blocking plate 2. The through holes 2x are inserted with screws 20, and the screws 20 are inserted into the screw insertion holes 1y of the main body plate 1 (see FIG. 4). Each blocking plate 2 can be attached to the main body plate 1 in various positions, and can also be attached so as to overlap each other. This allows the blocking plate 2 to be installed in a state where the object M to be installed is inserted into the base communication passage 1x of the main body plate 1, while avoiding the object M to be installed. For convenience of explanation, some of the blocking plates 2 are not shown in FIG. 4.

[0023] The screw fixing members 3 are disposed on the other surface of the main plate 1 at positions overlapping with the respective screw insertion holes 1y. Each screw fixing member 3 has a rectangular column shape extending in the height direction D3. The screw fixing members 3 have a laminated structure, for example, in which plywood and glass cloth are laminated in the through-hole opening direction D1, and are capable of repeatedly inserting and removing the screws 20 while holding the screws 20 with sufficient strength when the screws 20 are screwed into the screw fixing members 3. The screw fixing members 3 detachably fix the closing plate 2 to the main plate 1 by screwing the screws 20 inserted into the through-holes 2x in the closing plate 2 into the screw fixing members 3.

[0024] (Cover unit) Next, the first cover unit 101 and the second cover unit 102 will be described in detail. Returning to FIG. 2, the first cover unit 101 and the second cover unit 102 are disposed at an interval from each other in the through-hole opening direction D1. A base body 103 is disposed between the first cover unit 101 and the second cover unit 102. In this embodiment, the first cover unit 101 and the second cover unit 102 are disposed inside the through-hole X. The first cover unit 101 is disposed on the side of the base body 103 where the screw fixing member 3 is provided, and the second k-bar unit 102 is disposed on the side of the base body 103 where the closing plate 2 is provided.

[0025] 6, each of the first cover unit 101 and the second cover unit 102 has a closing device 10 that closes the through-hole X. The closing device 10 has a plate-shaped or block-shaped fiber aggregate 11, a frame 12 that holds the fiber aggregate 11, and a mesh member 13 that covers both surfaces of the fiber aggregate 11.

[0026] The fiber aggregate 11 is composed of an aggregate of fibrous insulating material, and is arranged so as to cover a part of the opening of the through-hole X from the through-hole opening direction D1 (see FIG. 2). In this embodiment, the insulating material is cellulose fiber. As shown in FIG. 7, the fiber aggregate 11 has an insulating material sheet (cellulose fiber sheet) 11a formed by compressing fibrous insulating material, and an adhesive layer 11b provided between the insulating material sheets 11a to bond the insulating material sheets 11a to each other. The insulating material sheet 11a is formed by compressing cellulose fiber in a thinly stretched state. Therefore, the fiber aggregate 11 is in a mass shape without gaps. The adhesive layer 11b contains a chemical (wood vinegar, creosote, peppermint, etc.) that has a high repellent effect on small animals such as mice, palm civets, raccoons, and weasels, especially mice. The adhesive that is the main component of the adhesive layer 11b is particularly preferably starch paste. The thickness dimension of the fiber assembly 11, that is, the dimension in the opening direction D1 of the through-hole, is, for example, 50 mm to 100 mm, and in this embodiment, it is 70 mm.

[0027] The fiber assembly 11 is provided so as to cover the base communication passage 1x of the base body 103 from the through-portion opening direction D1 (see FIG. 2).

[0028] Returning to FIG. 6, the frame 12 is a rectangular annular metal member that surrounds the side of the fiber aggregate 11. Thus, the frame 12 holds the fiber aggregate 11 while exposing at least a portion of the surface of each of the fiber aggregates 11 in the through-hole opening direction D1. The frame 12 is fixed to the main body plate 1 of the base body 103 by a bracket 12x with a bolt B1 and a nut N1 (see FIG. 2). Specifically, the bolt B1 is inserted through the main body plate 1, the bracket 12x of the frame 12 of the first cover unit 101, and the bracket 12x of the frame 12 of the second cover unit 102, and the first cover unit 101 and the second cover unit 102 are detachably fixed to the main body plate 1 by the nut N1.

[0029] The mesh member 13 is, for example, a wire mesh, and is provided on both surfaces of the fiber assembly 11 facing the through-hole opening direction D1. The mesh size is preferably such that small animals cannot pass through. Furthermore, the mesh member 13 is preferably thick enough to be easily cut with metal snips. The mesh member 13 may be provided on only one surface of the fiber assembly 11. Also, a perforated plate may be provided in place of the mesh member 13.

[0030] (Action and effect) According to the closing system 100 of the present embodiment described above, the penetration part X of the structure K can be closed by the closing device 10 constituting the cover units 101, 102. This makes it possible to prevent the spread of fire through the penetration part X. Furthermore, since the closing device 10 has the fiber aggregate 11 made of insulating material formed in a block shape without gaps, it has a heat insulating effect and an effect of reducing the air contained in the fiber aggregate 11, and even if the fiber aggregate 11 catches fire, the fire is easily extinguished. Therefore, the closing system 100 can exhibit very high fire resistance.

[0031] Furthermore, by hollowing out a part of the fiber aggregate 11, the object M to be installed can be penetrated through the closing device 10. Also, the fiber aggregate 11 from which a part has been hollowed out can be easily restored by filling it again with insulating material, etc. This makes it easy to replace and install the object M to be installed through the penetration part X. Furthermore, since insulating materials, especially cellulose fiber, have properties that small animals dislike (for example, the property of causing dehydration), damage to the closing device 10 by small animals can also be prevented.

[0032] The fiber aggregate 11 has a structure in which compressed heat insulating sheets 11a are laminated together with adhesive layers 11b, which further reduces the gaps in the fiber aggregate 11 and further reduces the amount of air contained in the fiber aggregate 11, thereby further improving the fire resistance of the fiber aggregate 11.

[0033] Furthermore, the adhesive layer 11b of the fiber assembly 11 contains an agent that has a repellent effect against small animals, which is highly effective in keeping small animals away and preventing damage to the closure device 10 caused by small animals.

[0034] In addition, since the mesh member 13 is provided on the surface of the fiber assembly 11, it is possible to effectively prevent damage to the fiber assembly 11 by small animals. Also, by cutting out a part of the mesh member 13, it is possible to arbitrarily set the area to be hollowed out in the fiber assembly 11 when installing the object M to be installed, and it becomes possible to accommodate objects M of various shapes and sizes.

[0035] Incidentally, in the base body 103, it is possible to easily install the object M by changing the position of the closing plate 2 while preventing small animals from entering the space S through the penetration part X. However, on the other hand, since the closing plate 2 has a plurality of through holes 2x for the screws 20, if the base body 103 is installed alone in the penetration part X, air will flow between the spaces S through the through holes 2x. This creates a risk of fire spreading, but in this embodiment, the base body 103 is provided so as to be sandwiched between the first cover unit 101 and the second cover unit 102 constituted by the closing device 10, so that the flow of air in the penetration part X can be blocked.

[0036] Therefore, by using the base body 103, it is possible to prevent small animals from entering the space S through the penetration part X, reducing the risk of electronic devices in the space S being damaged by small animals, while the cover units 101 and 102 can provide high fire resistance.

[0037] Moreover, the cover units 101 and 102 are fixed to the main body plate 1 of the base body 103 by bolts B1, so that they can be attached to and detached from the main body plate 1. Therefore, it is easy to replace only the cover units 101 and 102.

[0038] Furthermore, since the cover units 101, 102 are arranged to be positioned inside the penetration portion X, the entire closure system 100 can be installed on the structure K simply by fixing the cover units 101, 102 to the base body 103 in advance and then fixing the base body 103 to the structure K, resulting in extremely good workability.

[0039] Although the embodiments of the present invention have been described above in detail with reference to the drawings, the configurations and their combinations in the above-mentioned embodiments are merely examples, and addition, omission, substitution, and other modifications of the configurations are possible without departing from the spirit of the present invention. Furthermore, the present invention is not limited to the embodiments, but is limited only by the claims.

[0040] For example, it is not necessary to provide both the first cover unit 101 and the second cover unit 102, and only one of them may be provided. Also, the first cover unit 101 may be fixed to the screw fixing member 3 of the base body 103 by screwing.

[0041] Furthermore, the fiber assembly 11 does not necessarily have to be composed of the heat insulating sheet 11a and the adhesive layer 11b, and the frame 12 may be filled with fibrous heat insulating material by pushing it in so as to leave no gaps.

[0042] 8, the first cover unit 101 and / or the second cover unit 102 may be provided so as to cover the entire opening of each of the penetration parts X, and fixed to the structure K by anchor bolts B2.

[0043] Also, as shown in FIG. 9, the base body 103 may not be provided, and only the first cover unit 101 and / or the second cover unit 102 may be installed on the structure K.

[0044] The multiple closure plates 2 of the base body 103 may be plates of different shapes and sizes depending on the sizes and arrangement positions of the cables and piping.

[0045] Furthermore, the closing device 10 constituting the first cover unit 101 and the second cover unit 102 may be composed only of the fiber assembly 11 having the heat insulating sheet 11a and the adhesive layer 11b. [Industrial Applicability]
