Description

[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention relates to an attic facility in which sprinkler piping and electrical wiring are arranged in an attic space, and the sprinkler piping is supported by a ceiling support section above the ceiling via a hanging fixture. Concerning the manner in which it is enforced.

0002

[Prior Art] In the past, sprinkler piping and electrical wiring were installed separately on ceiling supports such as floor slabs because the construction of sprinkler piping and the construction of electrical wiring for light and heavy electricity were completely different industries. Ta.

0003

[Problems to be Solved by the Invention] Accordingly, when using the above-mentioned conventional technology, the labor-intensive work of attaching a hanging fixture, which serves as an attachment part for sprinkler piping and electrical wiring, to a ceiling support part such as a slab is no longer necessary. It was necessary for each wiring work, and the workability was poor. An object of the present invention is to provide attic equipment that can be constructed with good workability, and a construction method useful for constructing the attic equipment.

0004

[Means for Solving the Problems] A characteristic feature of the attic facility according to the present invention is that the electrical wiring is attached to the sprinkler piping or the hanging fixture.

[0005] In the above ceiling equipment, the pipe to which the unwinding pipe to the sprinkler head of the sprinkler pipe is connected is arranged in a position along the equipment line in the ceiling where the electrical appliances are lined up in a straight line. It is preferable that there be.

[0006] The feature of the method for constructing ceiling equipment according to the present invention is that before constructing the ceiling base, the sprinkler piping is attached to the ceiling support part, and the sprinkler piping or a hanging device for supporting the sprinkler pipe to the upper ceiling support part is installed. Construction work will be carried out to install electrical wiring.

[0007]

[Function] According to the above-ceiling equipment of the present invention, as a hanging device for supporting the sprinkler piping and electrical wiring on the ceiling supporting portion, only a hanging device that supports the sprinkler piping on the ceiling supporting portion is required, which is a time-consuming hanging device. It is possible to halve the number of man-hours required to install the product on the ceiling support. Moreover, since the sprinkler piping and its hanging equipment are functionally sturdy and can be firmly attached to the ceiling support, there is no need to support the electrical wiring on the ceiling support through the hanging equipment. However, it is possible to reliably support electrical wiring.

In particular, when the sprinkler piping is installed along the equipment line on the ceiling, the sprinkler piping is sturdy and can be firmly attached to the ceiling support. Since the pipe can support electrical equipment such as lighting fixtures placed on the equipment line, it is possible to install the electrical wiring and connect the electrical wiring to the electrical equipment at the same time, making it possible to complete electrical work in one piece. Can be done.

According to the construction method of the present invention, the construction of the sprinkler piping and the electrical wiring can be carried out without being obstructed by the ceiling base. Moreover, since the electrical wiring is attached to the sprinkler piping or its hanging fixture, there is no need to construct a hanging fixture for attaching the electrical wiring to the ceiling support. In particular, when applied to the attic facility according to claim 2, electrical appliances such as lighting fixtures can also be temporarily fixed and electrical wiring can be connected before construction of the ceiling base.

0010

[Effects of the Invention] Therefore, the present invention has been able to provide an attic facility and a method for constructing the same, which can significantly reduce the number of construction steps and perform sprinkler work and electrical wiring work with good workability.

[Example] As shown in Fig. 1, the attic equipment that targets the attic space 3 between the system ceiling 1 and the slab 2 on the upper floor, which is an example of the upper ceiling support part, is equipped with sprinkler piping. 4 and electrical wiring 5. The ceiling base 1A of the system ceiling 1, as shown in FIG. It is configured to be supported in a parallel position arrangement. As shown in FIG. 4, the system ceiling 1 includes a plurality of equipment lines 1B in which electrical appliances 9 are arranged in a straight line along the longitudinal direction of the field edge 8.

As shown in FIGS. 2 and 4, the electric appliances 9 are lighting appliances 9A arranged at intervals in the longitudinal direction of the line.
and lighting fixtures 9A lined up with space between adjacent lighting fixtures 9A.
and various detectors (fire detectors, fire detectors,
smoke detectors, infrared detectors for crime prevention, etc.) and light electrical appliances 9B such as speakers. The lighting fixture 9A is supported by the ceiling base 1A by placing each of its widthwise ends on the edge 8 located on both sides of the lighting fixture 9A, and the ceiling board 10 forming the ceiling surface is also supported by the ceiling base 1A. , both ends in the width direction are supported by ceiling bases 1A located on both sides thereof.

The sprinkler piping 4 is for supplying water to a sprinkler head 12 facing the space below the ceiling through a hole 11 formed in a predetermined location of the equipment plate P, as shown in FIG. As shown in FIG. 2, the main pipe 4A and the equipment line 1B are arranged directly above the equipment line 1B in a posture along the equipment line 1B, and the branch pipes 4B are branched and connected to the main pipe 4A.
It consists of an unwinding pipe 4C which is branched and connected in a vertical position at each location corresponding to the hole 11, and the branch pipe 4B is connected to the hanging tool 1.
It is supported by the slab 2 via 3. A sprinkler head 12 is attached to each hole 1 at the lower end of the unwinding pipe 4C.
