[0003]

[Problems to be solved by the device]

 However, the size or shape of the partition through-holes formed in the floor, wall, etc. differs depending on the type and number of inserted cable wires, the size of the pipe, and the like. Therefore, in the above-mentioned Japanese Patent Laid-Open Nos. 1-278216 and 2-15169, for example, when the compartment through-hole is small, the filler receiving device cannot be stored in the compartment through-hole, while the compartment through-hole is small. When the ratio is large, a large gap is opened between the half containers a and a and between the filler receiving members b and b, so that the filler cannot be received. Therefore, in the above-mentioned case, there is a problem in that various kinds of materials that can correspond to the size and shape of the partition through holes must be manufactured in advance. Further, in the case of the one disclosed in JP-A-1-278216, an insertion hole d for inserting an insertion member such as a cable wire or a pipe is provided at the center of the two filler receiving portions a2 as shown in FIG. In Japanese Utility Model Laid-Open No. 2-15169, as shown in FIG. 7, the filler receiving parts b, are provided at the center of the b. However, if there are a plurality of cable wires to be inserted, all the cable wires are divided. It does not necessarily pass through the center of the through hole, and some of them may pass through the inner wall surface of the partition through hole. Therefore, in such a case, there is a problem that the cable wire cannot be linearly inserted, and in the case of a pipe, it cannot be inserted. Further, the above-mentioned one has a problem that it is inconvenient to handle because it is bulky during storage or transportation because it has a three-dimensional shape.

The present invention has been proposed in view of the above circumstances, and an object of the present invention is to use it regardless of the size and shape of the partition through-hole, and further, to use the cable wire passing through the inner wall surface of the partition through-hole. Another object of the present invention is to provide a filler receiving device in a partition penetrating portion for a cable wire, a pipe, etc., which can also be inserted through the like.

[0005]

[0006]

[Action]

 In the present invention, since the filler receiving portion is formed by bending a plurality of bendable receiving pieces inward from the lower end side at a predetermined length position inward of the partition through hole, the size and shape of the partition through hole can be adjusted. It can be formed by appropriately bending it, and can be used regardless of the size and shape of the partition through hole. Further, since the insertion hole for passing the cable wire, the tube, etc. in the filler receiving portion is formed between the plurality of bent pieces formed by bending the plurality of receiving pieces, it is one of the plurality of cable wires to be inserted. If the book comes close to the inner wall surface of the compartment through-hole, for example, cut or bend one end of the thin plate to shorten the bent piece, or pass it through the gap between the receiving pieces. This makes it possible to accommodate cable wires that come close to the inner wall surface. Moreover, at that time, if the bending of the other receiving piece is made so as to correspond to the cable line passing through the center of the partition through hole, the entire through hole does not become large, and it becomes difficult to receive the filler. Can be prevented.

【Example】

 An embodiment of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a side view of an embodiment of a filler receiving device in a partition penetrating portion for cable wires, pipes, etc. of the present invention before being mounted in the partition penetrating hole, and FIG. It is a perspective view at the time of doing.

The filler receiving device 1 of the present embodiment includes a filler receiving portion 2 arranged in a lower portion, a supporting portion 3 arranged in an upper portion, and a connecting portion 4 arranged between them. It consists of Further, in this embodiment, these are composed of a thin plate-like body made of one metal plate having a thickness of about 0.6 mm, and can be freely bent or bent at an appropriate position. Has been done. It should be noted that this thin plate-like body may be made of a non-combustible material that can be bent or bent. Further, in this embodiment, it is assumed that the filler receiving portion 2, the supporting portion 3 and the connecting portion 4 are integrally molded by continuously pressing a long thin plate having a predetermined height in the lateral direction. Then, the filler receiving tool 1 shown in FIG. 1 is obtained by cutting the continuous body with a predetermined length. Therefore, the filler receiving tool 1 in a manufactured state has a flat plate shape, and is attached to the partition through hole K for a cable wire, a pipe or the like which is bored in a partition wall such as the floor surface T shown in FIG. When bent, it is bent or bent by hand to form a round tube, or if necessary, a square tube.

The connection portion 4 has a rectangular shape with a predetermined height in the state of being manufactured as shown in FIG. 1, and includes a plurality of filler holes 41 ... 41 formed along the longitudinal direction. ing.

The filler receiving portion 2 is for receiving the filler J (illustrated in FIG. 5) with which the compartment through-hole K is filled, and the plurality of receiving portions extending downward from the connecting member 4. It consists of pieces 21 ... 21. As shown in FIG. 1, these receiving part pieces 21 ... 21 are arranged in parallel at predetermined intervals along the longitudinal direction at a predetermined width, but the invention is not limited to this aspect, and for example, each receiving part piece 21. The width and shape of 21 may be different from each other, or only the score line may be provided without providing the interval between the receiving part pieces 21. Further, in the case where only the score line is provided, the filler J can be sufficiently rotated also to the back side by forming a hole in the receiving portion pieces 21 ... 21.

Each of the receiving part pieces 21 ... 21 is bent at a position of a predetermined length from the lower end to the front side (or the rear side) at a substantially right angle to form a bending piece 22, which is shown in FIG. 22 is assembled in the compartment through hole K, the bent pieces 22 ... 22 gather to receive the filler J, and the cable wires between the tips of the bent pieces 22. An insertion hole 23 through which the insertion member S such as a tube is inserted is formed. The bending angle of the bending piece 22 is not limited to the one in which all the receiving part pieces 21 ... 21 are made substantially right angle, and some pieces may be made with some inclination.

The support portion 3 supports the filler receiving tool 1 arranged in the compartment through-hole K so as not to drop, and a plurality of support pieces 31 extending upward from the connecting member 4 ... It consists of 31. These support pieces 31 ... 31 are arranged side by side with a predetermined width at predetermined intervals along the longitudinal direction in the same manner as the above-mentioned receiving piece pieces 21 ... 21 forming the filler receiving section 2. It has the same shape. In this support piece 31 ... 31, the width of each support piece 31 ... 31 may be different from each other, or only the score line may be provided without providing the space between the support pieces 31 ... 31. Further, it may be formed in a shape different from that of the receiving portion pieces 21 ...

Each of the support pieces 31 ... 31 is bent rearward at a position of a predetermined length from the upper end as shown in FIG. It forms a portion that engages with a partition wall such as the floor surface T around the hole K.

Next, a method of using the filler receiving device 1 of the present invention will be specifically described. First, when it is mounted in the circular partition through-hole K, as shown in FIG. 1, it is cut from the continuous body at a substantially inner peripheral length of the partition through-hole K. The cutting may be longer than the inner circumference or may be slightly shorter than the inner circumference. As a result, one filler receiving device 1 that fits the compartment through hole K is obtained. Then, the lower end portions of the obtained receiving portion pieces 21 ... 21 of the filler receiving device 1 are bent forward from the lower end at a predetermined length position to form bent pieces 22. At that time, the length of the bending pieces 22 ... 22 may be set appropriately according to the depth, diameter, etc. of the partition through hole K, but the bending angle (A) is adjusted even when the bending pieces 22 ... 22 are long. Thus, the size of the insertion hole 23 formed between the tips of the bent pieces 22 ... 22 can be adjusted. If necessary, the lower ends of the receiving part pieces 21 ... 21 may be cut off appropriately and then bent.

Next, the right end side of the connecting portion 4 is bent so as to be aligned with the left end side to form the connecting portion 4 into a cylindrical shape. At this time, in the above cutting, if the inner peripheral length of the partition through hole K is too long, the right end side is overlapped with the left end side, or the bending angle (A) is reduced, and the bending piece 22 ... The tip of 22 may be adjusted so as to incline upward. As a result, as shown in FIG. 3, each of the bending pieces 22 ... 22 is arranged so as to face the axial center direction of the ring, is formed so as to receive the filler J, and the insertion hole 23 is formed in the axial core portion. Is formed. At that time, when a plurality of cables or pipes S are inserted, for example, when one of them is near the inner wall surface N of the partition through hole K without passing through the shaft core portion, when forming the bending piece 22, As shown in FIG. 4, one receiving part piece 21 is bent in an oblique direction in advance to form a gap between adjacent bending pieces 22, or one receiving piece 21 is formed as shown by a dotted line in FIG. It is sufficient to cut the lower end of the piece 21 or fold it back to overlap and shorten it. By doing so, the cable S or the like that does not pass through the shaft core portion can be inserted straightly, and on the other hand, since a gap is partially formed, it is possible to prevent the filler J from dropping. When the partition through hole K has a rectangular shape, the connecting portion 4 may be manually bent into a rectangular tube shape to form the partition through hole K along the inner wall surface N.

Then, in this state, the hand that has been bent in the compartment through hole K is released. As a result, the elastic force of the connecting portion 4 allows the connecting portion 4 to abut and lock the inner wall surface N of the partition through hole K in a pressed state.

Next, each of the support portions 3 protruding from the upper surface of the floor T or the like having the partition through holes K formed therein is bent outward to form the locking piece 32. As a result, the filler receiving tool 1 is securely locked to the upper surface of the floor T or the like, and will not fall off from the compartment through hole K even if a load is applied. This completes the mounting. Therefore, everything from separation from the continuum to installation can be adapted according to the shape, size, etc. of the partition through-hole K at the construction site, and the partition through-hole K can be used in advance as in the conventional case. It is possible to deal with all compartment through holes K without preparing various kinds of corresponding ones. Further, a cable S or the like which does not pass through the shaft core portion can be inserted.

Then, from this state, the filler J is filled as shown in FIG. At the time of this filling, the filler J penetrates from the filler holes 41 ... 41 between the connection part 4 and the inner wall surface N of the partition through hole K, and also the gap between the receiving part pieces 21 and 21 and the support. 21 and the inner wall surface N, and between the support pieces 31 ... 31 and the inner wall surface N to enter the filler receiving member 1 and the partition through hole K. It is possible to prevent the formation of a space portion with the inner wall surface N of the above, and it is possible to exert a fire spread prevention effect.

In this embodiment, the filler receiving portion 2, the supporting portion 3 and the connecting portion 4 are integrally provided, but the present invention is not limited to this aspect, and each of them may be a separate body. You may connect them with each other. Further, the filler receiving portion 2 and the supporting portion 3 may be composed of a plurality of elongated thin plates, and further, a plurality of them may be connected laterally by a string member, as appropriate. Can be changed.

Further, in the present embodiment, the whole is made of a thin plate, but the present invention is not limited to this, and it may be made of a wire rod, a mesh or the like, and any bendable one can be used. In the following, another embodiment composed of a wire material and a net-like material will be described with reference to the drawings.

6 (A) and 6 (B) relate to an example constituted by a wire rod, and the example shown in FIG. 6 (A) shows a steel wire having a wire diameter of about 2 mm. The filler receiving portion 2 and the supporting portion 3 are integrally formed by arranging a plurality of them in the vertical direction with t1 set to about 20 mm, and two steel wires having the same diameter are arranged in the horizontal direction. 6 and 6 are fixed to each of a plurality of longitudinally arranged steel wires by welding. On the other hand, the locking piece 32 and the bending piece 22 are formed by bending the upper part and the lower part of each of the plurality of steel wires arranged in the vertical direction. Then, the locking pieces 6, 6 are bent into a curved shape to form a round tube shape shown in FIG. 6 (A). In addition, in the embodiment shown in FIG. 6 (B), a plurality of steel wires are arranged in the longitudinal direction in the embodiment shown in FIG. 6 (A), whereas in the embodiment shown in FIG. The filler receiving portion 2 and the supporting portion 3 are formed by bending the wire, and are formed in the same shape as that of FIG. 6 (A). With the above-described structure, the cable closer to the inner wall surface N of the partition through hole K can be passed not only between the tips of the bent pieces 22 ... 22 but also between the steel wires. In addition, the material cost is reduced, and the filler holes 41 ... 41 are not required unlike the previous embodiment, and the manufacturing cost can be reduced. Moreover, during storage and transportation, it can be carried out as it is with a plate-shaped body in which straight steel wires are arranged in the vertical and horizontal directions, which is convenient without being bulky. The wire diameter of this wire is not limited to the above-mentioned size, and may be any one that can be bent by hand. Further, the interval t1 between the steel wires may be such that the filler J does not fall from the gap, more specifically, about 50 mm or less.

FIG. 7 relates to an embodiment constituted by a mesh body. In this embodiment, a plurality of steel wires having a wire diameter of about 0.5 to 1 mm are sequentially knitted to each other so that the opposite side interval t2 is 15 mm. The filler receiving portion 2 and the supporting portion 3 are integrally formed from a flat plate-like wire net having a plurality of hexagonal holes each having a certain size. The locking piece 32 and the bending piece 22 are formed by bending the upper and lower portions of a flat plate-like wire mesh. By doing so, it is possible to easily form from a commercially available wire mesh, and it is not necessary to provide the filler holes 41 ... 41 as in the case of the wire rod, and the manufacturing cost can be kept low. . Also in this case, when it is stored or transported, it can be handled as it is in a flat plate shape before being bent and the like, which is convenient because it can be performed without being bulky. The size of the holes of this wire mesh may be such that the filler J does not fall from the holes, more specifically, about 50 mm or less. The above is the description of another embodiment.

In the above embodiment, the thin plate, the wire rod, and the net-like member are formed independently, but they may be formed by combining them and can be appropriately changed.
