BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe shaft cover installed in a predetermined section through which a brace passes in a building where the brace is installed.

[0002]

BACKGROUND ART For example, when a pipe shaft is made of a panel in a steel frame building having a pin brace structure, the pipe shaft cover is installed on-site in the following manner. That is, first, as shown in FIG. 4, the pipe shaft cover 1 having a length from the lower end to the upper end of the pipe shaft cover installation section is prepared. In the case of the pipe shaft cover 1, the side plates 2 and the front plate are separate bodies, and they are assembled as an integral cover 1 on site. A notch 4 is formed in advance at a portion of the side plate 2 where the beam 3 is located.

When the side plates 2 and the front plate are installed, the braces 5 are installed between the beams 3 in a diagonal shape.
The part through which is cut is laterally cut on site to form a larger cut portion 6 as shown by the chain double-dashed line. Next, as shown in FIG. 5, after installing the both side plates 2 and the front plate so that the brace 5 is inserted into the large cutout portion 6, a small width corresponding to the diameter of the brace 5 is formed. The steel plate 8 on which the cutout portion 7 is formed is attached so as to cover the larger cutout portion 6. Thereafter, the small cut portion 7 and the periphery of the beam 3 are closed with rock wool (not shown) for fire protection.

[0004]

In the case of the conventional pipe shaft cover 1 described above, the lateral cutting work for forming the large cut portion 6 is not easy at the site, and the smaller cut portion 7 is then formed. The work of covering the large excision portion 6 with the steel plate 8 on which is formed was also troublesome.
In particular, when the brace 5 is located at a position far from the side edge of the side plate 2 or the front plate, the cutting portion 6 becomes considerably large and the work is difficult.
As a result, the cover 1 above the cutout portion 6 may become unstable and may be broken. Therefore, an object of the present invention is to provide a pipe shaft cover that can easily perform a work for passing an installed brace.

The first member and the second member may have separate side plates and front plates before the pipe shaft cover is installed, or both side plates and the front plate may be connected to form an integral body. It may be one that has become.
The joint material may be provided on the upper portion of the first member or the lower portion of the second member as a separate member by joining, or may be integrally provided by simultaneous molding. Further, in this pipe shaft cover, a plurality of holes through which the brace is inserted are formed in the joint material, and the upper or lower part of the hole where the brace is actually inserted may be cut off. Good.

[0007]

When the pipe shaft cover according to the present invention is installed, for example, the first member and the second member provided with the joint material at the bottom thereof are prepared. First, the first member is arranged in the pipe shaft cover installation section, and then a cut portion for inserting a brace is formed in a vertical direction in a portion of the joint material where the brace is located. When the second member provided with the joint material in which a plurality of holes are formed is used in forming the cutout portion, it is necessary to partially cut out only the lower portion of the hole portion through which the brace is inserted. Good work facilitates on-site work.

Next, the second member is placed on the first member such that the brace is inserted into the cutout portion of the joint material. Then, the pipe shaft cover according to the present invention is installed by connecting the second member to the first member through the joint material. In this way, the cutout for passing the brace through the pipe shaft cover may be formed vertically from the lower part of the joint material, and when the brace is located far from the side edge of the side plate or front plate. However, since the same short excision part can be formed,
Work becomes easy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A pipe shaft cover according to an embodiment of the present invention will be described with reference to FIGS. The pipe shaft cover 11 of the present embodiment is installed in a predetermined section through which the brace 33 of the house 34 in which the brace 33 is installed diagonally between the beams 32 of the frame 31 passes. This frame 31 is a pillar,
It is constructed by building with beams 32 and so on. A panel 36 is attached to the outside of the frame 31. The pipe shaft cover 11 is provided with a first member 12 and a second member 14 having a joint member 13 provided at a lower portion thereof, and both members 12 and 14 are connected via a joint member 13.

As shown in FIGS. 1 and 2, the first member 12
Has a length from the lower end of the pipe shaft cover installation section to the substantially brace installation site, and is composed of three points: a front plate 15 and both side plates 16 joined in a U shape by a connecting fitting (not shown). ing. At the center of the front plate 15,
17 are provided. The second member 14 has a length from a substantially brace installation portion to an upper end of the pipe shaft cover installation section, and like the first member 12, a front plate 19 joined in a U-shape by a connecting fitting 18, and It is composed of three points on both side plates 21. In addition, in FIG. 1, both side plates 1
6,21 is shown only for one and omitted for the other.

These front plates 15 and 19 and both side plates 16 and 21
May be integrally manufactured with an inorganic building material such as an ALC plate, or may be assembled with a surface material, a back surface material, a side material, and the like. The joint material 13 has a plurality of holes 22, which are slightly larger than the brace 33, for example, four or five holes 22 formed at equal intervals. The joint material 13 is fixed to the lower portion of the second member 14 on the back surface side with screws or the like. The joint material 13 is made of, for example, steel so as to have a fireproof property.

The pipe shaft cover 11 as described above is installed as follows in a house 34 constructed by a framed panel construction method, for example. In the house 34, braces 33 are installed diagonally between the beams 32 of the frame 31. First, as shown in FIG. 1, the first member 12 in which the front plate 15 and both side plates 16 are joined in a U shape is arranged in a pipe shaft cover installation section so as to surround a plurality of pipes 35.

Next, the lower portion 13A of the hole 22 in which the brace 33 of the joint material 13 is located is vertically cut by a cutter to form a brace insertion cutout portion 23. Next, as shown in FIG. 1, the front plate 19 and the side plate 21 of the second member 2 are braced 33 to the cutout 23 of the joint material 13, respectively.
Is placed on the first member 12 so that Then, the front plate 19 and the side plate 21 of the second member 12 are joined together, and the joint material 13 is connected to the upper part of the first member 12 to install the pipe shaft cover 11 according to the present invention. Thereafter, rock wool (not shown) is filled in the gaps such as the holes 22 and the beams 32 of the joint material 13 to perform fire prevention treatment.

Pipe shaft cover 11 according to the above embodiment
According to the above, the cutting portion 23 for passing the brace 33 through the pipe shaft cover 11 is formed by vertically cutting the lower portion 13A of the hole portion 22 where the brace 33 of the joint material 13 is located by cutting the brace insertion cutting portion 23. To form the brace
The same short cut, whether 33 is near or far from the side edges of the side plates 16,21 or the front plates 15,19.
23 formation is enough. Therefore, when the brace 33 is located far from the side edges of the side plates 16 and 21 or the front plates 15 and 19, the brace is passed through as compared with the conventional pipe shaft cover which requires the formation of a long cut portion. It is easy to work for.

Further, since a plurality of holes 22 are already formed in the joint material 13, it is sufficient to insert two cutting lines in the vertical direction when forming the brace insertion cutout 23. When 22 is not formed, the cutting work can be simplified as compared with the case where a horizontal cutting line must be formed so as to be connected to the two vertical cutting lines.
Further, since the brace insertion cutting portion 23 formed in any portion in this way has a short length and is in the vertical direction, the cutting portion 23 covers the portion above the cutting portion 23. 11 will not be unstable.

Although the joint member 13 is provided in the lower portion of the second member 14 in the above embodiment, it may be provided in the upper portion of the first member 12 conversely. In this case, the brace insertion cutout portion is formed by vertically cutting off the upper portion of the hole portion 22 of the joint material 13 where the brace 33 is located. Further, in the above embodiment, the joint material 13 in which the plurality of holes 22 are formed at equal intervals is used, but a joint material in which no holes are formed may be used.
