Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure used to install a sprinkler in a system ceiling.

[0002]

[Prior Art]

 Conventionally, when a sprinkler is installed on the system ceiling, a water supply pipe called a branch pipe branched from the main water supply pipe is horizontally piped on the ceiling, and a sprinkler head and water supply pipe installed at appropriate places on the ceiling material are usually used. It was connected by a branch pipe made of hard material. For this reason, construction works include water supply pipes called branch pipes, ceiling foundation work, dimension measurement of the part to which the branch pipe is attached, cutting of the pipe to be the branch pipe, thread cutting, screwing the joint, rust prevention of the screw part, branch pipe The rest of the procedure is to attach the ceiling material and attach the sprinkler head.

[0003]

[Problems to be solved by the device]

 In the case of such a conventional example, since the above-mentioned procedure must be carried out, the pipe connection is divided into several steps, and the ceiling foundation work and the ceiling material attaching step come in on the way, so that it is necessary to check for water leaks each time. There is a problem that it takes time and effort to carry out the work because the water pressure test must be performed.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a sprinkler-installed system ceiling in which the construction work of the sprinkler can be reduced.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the system ceiling with built-in sprinkler of the present invention connects the upper end of the branch pipe 2 made of a flexible pipe to the water supply pipe 1 installed above the ceiling and attaches the joint 3 to the lower end of the branch pipe 2. Then, the sprinkler head 5 is connected to the joint 3 through the equipment plate 4, and the side edge of the equipment plate 4 is placed on the ceiling material support bar 6 provided on the ceiling to connect the equipment plate 4 and the ceiling material 7. I made it almost flush.

[0006]

[Action]

 Since the branch pipe 2 is a flexible pipe, the upper end of the branch pipe 2 is connected to the water supply pipe 1 before the system ceiling is installed, and the joint 3 is attached to the lower end of the branch pipe 2 and the equipment plate 4 is attached to the joint 3. After mounting the sprinkler head 5, the branch pipe 2 made of a flexible pipe is freely bent and positioned so that it does not get in the way, then ceiling work is performed, and after the ceiling work, the equipment plate 4 is attached to a predetermined place. Construction can be done with. As a result, the sprinkler construction and ceiling construction can be performed separately, which eliminates the waste of construction and improves workability. Also, the hydraulic test of the sprinkler can be done only once, and workability can be improved.

【Example】

 First, the embodiment shown in FIG. 1 will be described. A water supply pipe 1 called a branch pipe branched from a main water supply pipe is horizontally installed on the ceiling, and the water supply pipe 1 is attached to a suspender 8 hanging from a ceiling slab. A ceiling base material 9 is installed below the water supply pipe 1, and a ceiling material support bar 6 called a T bar is hung by a hanger 10 on the ceiling base material 9. The ceiling material 7 is arranged below the ceiling base material 9, and the side edges of the ceiling material 7 are placed and mounted on the ceiling material support bar 6. The equipment plate 4 is arranged between appropriate ceiling material support bars 6, and the side end of the equipment plate 4 is placed on the ceiling material support bar 6. The upper end of the branch pipe 2 made of a flexible pipe is connected to the water supply pipe 1, and the lower end of the branch pipe 2 is connected to the joint 3 by screwing. This joint 3 is placed on the equipment plate 4 via a spacer 11 made of an elastic body, and the sprinkler head 5 arranged below the equipment plate 4 is connected to the joint 3 via the equipment plate 4 and the spacer 11. It is screwed in and attached.

The construction procedure of the above will be described. Before starting work on the system ceiling, connect the upper end of the branch pipe 2 to the water supply pipe 1, attach the joint 3 to the lower end of the branch pipe 2, and fix the sprinkler head 5 to the joint 3 via the spacer 11 and the equipment plate 4. To do. At this time, the joint 3, the spacer 11, the equipment plate 4, and the sprinkler head 5 may be attached to the branch pipe 2 on the floor surface in advance, and the branch pipe 2 may be attached to the water supply pipe 1 later. When the sprinkler head 5 is tightened and attached, the equipment plate 4 is sandwiched between the sprinkler head 5, the joint 3 and the spacer 11 and completely fixed. At this stage, all the sprinkler piping connections have been completed, so a hydraulic test will be performed. Construction of the system ceiling will start when this water pressure test is completed. At this time, the branch pipe 2 is bent upward so as not to interfere with the construction of the system ceiling and temporarily fixed. After the foundation work of the system ceiling is completed, the equipment plate 4 with the sprinkler head 5 is placed on the ceiling material support bar 6 and set in a predetermined position, and the ceiling material 7 is placed on the ceiling material support bar 6. To install. In addition, the branch pipe 2 is constructed by bridging a channel or a pipe on the base material 9 of the Amai pipe and fixing it with metal fittings.

FIG. 2 shows another embodiment. In the case of the present embodiment, an annular spacer 11 having a substantially U-shaped cross section is interposed between the joint 3 and the equipment plate 4. The spacer 11 has a U-shaped cross section so as to be sufficiently elastic. The material of the spacer 11 is made of stainless steel in consideration of deterioration. When such a spacer 11 is used, the sprinkler head 5 can be securely and firmly attached to the sprinkler head 5, because a gap is less likely to occur due to the tightening and tightening of the sprinkler head 5 and variations due to member tolerances.

FIG. 3 shows still another embodiment. Bent parts 12 are provided on both side edges of the equipment plate 4 so as to surround the upper portion of the ceiling material support bar 6, and the side edges of the equipment plate 4 are attached to the ceiling material support bar 6 by pressing them with screws 13. It is fixed. In this case, the installation plate 4 can be firmly fixed to the ceiling support bar 6 and the sprinkler head 5 can be fixed only by the installation plate 4, and the branch pipe 2 is fixed by a member such as a channel, pipe or metal fitting so as not to shake. There is no need.

[0011]

[Effect of the Invention] Since the present invention forms the branch pipe with the flexible pipe as described above, the upper end of the branch pipe is connected to the water supply pipe before the system ceiling is installed, and the joint is connected to the lower end of the branch pipe. After attaching the equipment plate and sprinkler head to the joint and working on the sprinkler, flex the branch pipe made of a flexible pipe to a position where it does not get in the way by freely bending it, then perform ceiling work, and perform the ceiling work. It can be installed by attaching the plate to the specified place, and since the construction of the sprinkler is completed before the ceiling construction, the water pressure test only needs to be done once and the workability can be improved. Since construction work and ceiling work can be performed separately, waste of construction work can be eliminated, and the construction process can be shortened and workability can be improved. In addition, since the sprinkler head is mounted so as to be in close contact with the equipment plate, the sprinkler head will not tilt or shift.
