After this, the first and second branch pipes 14a, 14b of the second piping 9b are supported by means of fixation tools and fixed on the support bracket, and the second piping 9b is connected by means of flexible joints 9c to the first piping 9a made to be supported in suspension at a floor slab beforehand.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sprinkler mounting structure, and more specifically, a plurality of T-bars are arranged on a ceiling surface at predetermined intervals, and a ceiling material and a lighting fixture are installed on adjacent T-bars. In the above system ceiling, the present invention relates to a sprinkler mounting structure in which a sprinkler head is arranged so as to face under the ceiling.

[0002]

2. Description of the Related Art When installing a sprinkler on the ceiling, the main pipe connected to the water supply side is fixed to the floor slab, and a large number of threads are stretched in a grid on the ceiling surface. The intersections of the yarns are set as sprinkler head installation points, and the sub-pipes connected to the sprinkler heads are fixed to the channels or T-bars suspended from the floor slab with the sprinkler heads positioned at these intersections, respectively. After connecting the sub pipe and the main pipe, after that, a sprinkler head penetrating hole is formed in a portion of each ceiling plate which is installed between the T bars and corresponds to the sprinkler head, and the sprinkler head is attached to the ceiling plate. It is arranged in a penetrating state.

In the above-mentioned mounting method, the tension position for tensioning a large number of yarns at a predetermined position must be marked on the side wall surface while measuring the dimensions before the installation work of the sprinkler piping. The work is troublesome and troublesome, and fixing the sub-pipe to the channel or T-bar while visually aligning the sprinkler head at the intersection of the stretched threads is a very troublesome work, and the working time is There was a lot of inconvenience. or,
If the above-mentioned tensioning work is not performed before the work of arranging the basic constituent members of the system ceiling such as hanging bolts and channels that are hung from the ceiling is completed, those basic constituent members will be an obstacle when tensioning the thread. It was very difficult to do, and there was a disadvantage in terms of work that was restricted by the work order of the system ceiling.

Then, as a means for solving the above-mentioned inconvenience, for example, there is one disclosed in Japanese Patent Laid-Open No. 6-70994. This forms an installation hole for inserting the sprinkler head between the T-bars as slit-forming members that oppose each other with a small space between them, and contacts the upper end surface of the T-bar so that the vertical position of the sprinkler head can be adjusted. A restricting surface for restricting was provided in the installation tool of the sprinkler head to facilitate the vertical positioning of the sprinkler head, and the work of disposing the basic constituent members of the system ceiling such as channels and T-bars was completed. I am able to do the work later.

However, although the sprinkler head can be easily positioned in the vertical direction, no horizontal positioning means for the sprinkler head, which is required for the equipment, is provided, and a large number of sprinkler heads are provided. Each of them must be arranged while being positioned in the horizontal direction, and there is a problem in that work efficiency is lowered in this respect.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned situation, the present invention is to solve the problem that the sprinkler head can be easily positioned in the vertical direction, and the sprinkler head can be positioned in the horizontal direction. The point is that it can be easily positioned.

[0007]

In order to solve the above-mentioned problems, the present invention has a plurality of T-bars arranged at predetermined intervals on the ceiling surface, and a ceiling material and a lighting fixture between these adjacent T-bars. And the sprinkler pipe is composed of a first pipe connected to the water supply side and a second pipe connected to the sprinkler head, and the sprinkler head side portion of the second pipe is penetrated to the lighting fixture. A plurality of mounting portions for mounting are formed, and the lighting device has the second portion.
After the pipe is attached, the first pipe and the second pipe are connected by a connecting pipe, the connecting pipe is a flexible joint, and the attaching portion is a broadcasting speaker, an emergency light, a fire detector, It is also used as a mounting part for light electrical equipment such as outlets.

[0008]

Since a plurality of mounting portions for mounting the sprinkler head side portion of the second pipe in a penetrating state are formed in the lighting fixture along the horizontal direction, after the lighting fixture is installed on the T bar, 2 By simply attaching the sprinkler head side parts of the piping to the mounting part of the lighting fixture in order to position the sprinkler head in a predetermined position, not only to position the sprinkler head in the vertical direction but also to position it in the horizontal direction. It can be installed in a closed state.

By making the connecting pipe connecting the first pipe and the second pipe a flexible joint, the flexible joint absorbs even if the connecting distance between the first pipe and the second pipe changes a little. The first pipe and the second pipe can be connected together.

By using the mounting portion as a mounting portion for light electric equipment such as a broadcasting speaker, an emergency light, a fire detector, an outlet, etc., a broadcasting speaker, an emergency light, a fire detector, an outlet, etc. There is no need to specially install a mounting part for light electrical equipment, and the work time of the system ceiling can be shortened accordingly.

I have to. Then, the mounting portion 6c is present in a direction orthogonal to the longitudinal direction of the bulkhead 6b, and the distance between the mounting portions 6c is within a range determined by the installation standard of the sprinkler head 10a. The arrangement pitch r between the lighting fixtures 6 is set to 2500 mm. The arrangement pitch r between the lighting fixtures 6 is the vertical and horizontal dimensions of the room, that is, the dimension X between the columns 28 and 28, the ceiling height, the standard indoor illuminance of the lighting fixtures 6, and the installation reference distance of the sprinkler head 10a. Is determined in consideration of, for example, the dimension X between columns
Is 7.5 m square, the arrangement pitch r between the lighting fixtures 6 is set to 2.5 m, which can be equally divided by the integer (3). or,
Mounting pitch R of the mounting portion 6c formed on the lighting fixture 6
= 420 mm is the maximum arrangement pitch r of the arrangement pitch r of the lighting fixture 6 in the case of 9 m square so that the dimension X between the pillars can be applied to any dimension of 7.5 m to 9 m square,
That is, the mounting portion 6c in a direction orthogonal to the mounting portion 6c of the lighting fixture 6 arranged at the arrangement pitch r = 3m in the case of 9 m square.

The mounting pitch Y of the sprinkler head 10a in the longitudinal direction of the umbrella portion 6b is set to 37.
80 mm, and the arrangement pitch r of the lighting fixtures 6 is set to 250
Although the distance is set to 0 mm, any distance may be set as long as the distance Z between the sprinkler heads 10a does not exceed 4600 mm. The distance Z between the sprinkler heads 10a of 4600 mm indicates that the structure of the building is a fireproof structure. If the structure of the building is a non-fireproof structure, the distance Z between the sprinkler heads 10a is 4 mm.
It is set to 200 mm. Incidentally, when the dimension X between the pillars is 8 m square, the arrangement pitch r between the lighting fixtures 6 is 2
In addition to 667 mm, the mounting pitch Y of the sprinkler head 10a in the longitudinal direction of the cap portion 6b is 3360 mm.
When the dimension X between the pillars is 8.5 m square, the arrangement pitch r between the lighting fixtures 6 is set to 2833 mm, and the sprinkler head 10 in the longitudinal direction of the cap portion 6b is set.
aMounting pitch Y is set to 3360mm and dimension between columns is X
Is 9 m square, the arrangement pitch r between the lighting fixtures 6 is set to 3000 mm, and the mounting pitch Y of the sprinkler head 10a in the longitudinal direction of the bulkhead 6b is set to 3360 m.
It is set to m.
