BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire extinguishing system in which a plurality of fire extinguishing heads are fixed to pipes arranged horizontally and arranged on a ceiling .
It is related to the arrangement method .

[0002]

2. Description of the Related Art For example, a foam fire extinguishing system is used to extinguish a combustible material fire in a building. The temperature of the installation atmosphere is sensed and a water extinguishing head [water + air foam + chemical foam stock solution] is used. Is sprayed to cut off the contact between the combustibles and the outside air by foaming, and to extinguish suffocation, which is effective for oil fires. Foam fire extinguishing equipment is constructed by installing pipes horizontally and at regular intervals on the ceiling in an atmosphere where combustibles are installed, attaching foam heads to the pipes at regular intervals, and connecting the pipes to a fire extinguishing pump. In the event of a fire, a fire extinguishing solution is mixed with water drawn up from a fire extinguishing water tank by a fire extinguishing pump at a fixed ratio to generate a foam fire extinguishing solution, and the fire is extinguished by leading the foam to a foam head through piping.

[0003]

However, the piping after the simultaneous release valve in the above-mentioned conventional fire extinguishing equipment involves a heavy labor because of the continuous upward screwing work of the prefabricated pipe. In addition, since a large number of thin pipes are provided, the scaffolds are frequently moved up and down, resulting in a high degree of danger and forcing heavy labor. Further, when the floor slab is a PC (precast concrete) slab, the accuracy of the insert work at the factory stage of the PC slab must be dependent on the PC slab maker, and the cost is high. In addition, when a post-punched anchor is used, there are problems that it is difficult to enhance the reliability, that a large amount of pricks cause heavy labor, and that the blackout cost increases. Therefore, an object of the present invention is to provide a method for arranging fire extinguishing equipment that eliminates the need for insert work for the work after the simultaneous release valve and improves safety and workability and shortens the process time.

[0004]

Means for Solving the Problems A method for arranging fire extinguishing equipment according to the present invention for achieving the above object is characterized in that the method is performed in the following procedure. First, pipes arranged in parallel are assembled so as to be connected to the simultaneous release valve, and a head for jetting out the fire extinguishing agent is attached to these pipes. In addition, these pipes are fastened to these lightweight sections in a state where the pipes are stretched between the lightweight sections that are arranged in parallel. Next, with the lightweight section steel kept horizontal, these lightweight sections, piping and head are raised to the ceiling. Thereafter, the lightweight steel is fixed to the ceiling.

[0005]

In the above fire extinguishing equipment arranging method, the pipes arranged in parallel are bridged and fastened between the light-weight steel sections arranged in parallel, whereby the pipes and the light-weight steel sections are integrated. Since these pipes are assembled to be connected to the simultaneous release valve and equipped with a fire extinguishing agent jetting head, fire extinguishing equipment equipped with a pipe and head connected to the simultaneous release valve is required. They will be pre-assembled together. Therefore, the fire extinguishing equipment pre-assembled in an integrated state is disposed on the ceiling.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the arrangement of fire extinguishing equipment according to the present invention.
FIG. 3 is a perspective view showing an embodiment of the method . FIG. 2 shows FIG.
FIG. 3 is an exploded view showing a detailed structure of a portion A in FIG.
FIG. 2 is an exploded view showing a detailed structure of a portion B in FIG. In the following embodiments, a foam fire extinguishing system will be described as an example of a fire extinguishing system.

The fire extinguishing system shown in FIG. 1 includes a plurality of (three in this embodiment) lightweight channel steels 1 (ie, channel-shaped lightweight steel members) arranged in parallel. These lightweight channel steels 1 are, for example, 3.2 mm thick and 40 mm × 4.
The size is 0 mm × 40 mm. A plurality of pipes 2 are arranged at predetermined intervals in such a manner as to be orthogonally crossed over the lightweight channel steel 1. A pipe (hereinafter, referred to as a main pipe) 2a is connected to these pipes 2 in a state of being bridged, and a housing-type pipe joint 16 is connected to the main pipe 2a. That is,
The pipe 2 is assembled so as to be connected to a simultaneous release valve (not shown) through the main pipe 2a and the housing type pipe joint 16.

In addition, as shown in FIG. 2, a plate-like mounting for fixing the lightweight channel steel 1 to the beam 3 horizontally mounted on the ceiling is provided at a plurality of locations of each lightweight channel steel 1. Hardware 4
(9 pieces in this embodiment) are attached using screws 5 and nuts 6.

As shown in FIG. 3, a mounting bracket 7 is attached to a portion B of the main pipe 2a spanned between the pipes 2 for the same purpose. The mounting bracket 7 includes a hanging band 8 attached to the main pipe 2a and a crocodile-shaped clip portion 9. The connection between the suspension band 8 and the clip portion 9 is performed using a screw 10 and a nut 11, and the fastening amount of the clip portion 9 is performed using a screw 12 and a nut 13.
These mounting brackets 7 can also be mounted on the pipe 2.

Further, a foam head (ie, head) 1 for ejecting a fire extinguishing agent is provided at a predetermined position on the lower surface of the pipe 2.
4 is attached (however, the attachment of the foam head 14 is performed after the pipe 2 is washed). Further, a sensing head 1 for monitoring the temperature in the atmosphere for each predetermined position of the pipe 2
5 is attached.

As shown in FIG. 1, the fire extinguishing system pre-assembled on the floor as described above has the lower portions of the light-weight channel steel 1 at both ends placed on the lifts of a plurality of (four) lifting devices 17. Put on. Then, each lifting device 17 is simultaneously driven so that each lift portion rises at the same speed at the same time. When the fire extinguishing equipment reaches a predetermined position near the ceiling, the driving of each lifting device 17 is stopped. Stopped.

Next, a mounting bracket 4 for fixing the lightweight channel steel 1 to the beam 3 and a mounting bracket 7 for suspending the main pipe 2a (further, the pipe 2) from the beam 3 are attached to the beam 3. Attach to each horizontal part. In the case of the lightweight channel steel 1 used for a parking lot floor or the like, the fireproof steel is not coated with fireproof, and the suspended object can be directly attached to the beam 3. In addition, if the light-weight channel steel 1 is arranged with the flat surface facing upward, the contact with the beam 3 can be brought into surface contact, and the mounting bracket 4 can have a simple configuration with only one plate.

In this case, the lightweight channel 1 and the beam 3 are fixed to each other by using the mounting bracket 4, the screw 5 and the nut 6, and the main pipe 2a and the beam 3 are fixed to the mounting bracket 7 and the screw 3. 12
And the nut 13. Furthermore, the mounting bracket 7
In, the fixing of the suspension band 8 and the pipe 2 is performed using the screw 10 and the nut 11. Therefore, both the mounting brackets 4 and 7 can have a simple structure with a minimum number of parts. When the installation of the fire extinguishing equipment on the beam 3 (that is, the fixing of the lightweight channel 1 to the beam 3) is completed,
Each of the lifting devices 17 is driven such that its lift portion is lowered.

As described above, by assembling fire extinguishing equipment on the floor and attaching it to the beam 3 using the lifting device 17, the following specific effects can be obtained. . (1) Working at high places and raising and lowering the scaffolding are reduced, and safety is improved. (2) Lighter work can be achieved by increasing the rate of downward work on the floor and decreasing the elevation of the scaffold. With the reduction in work, the work density is increased, and work efficiency can be improved. (3) Insert work is not required. (4) As a result of pre-assembly of units on each floor, the process can be shortened. (5) Since the position of the fire extinguishing equipment is determined by the connection port of the main pipe (that is, the connection part to the simultaneous opening valve), blackout is not required.

In the above embodiment, the fire extinguishing equipment is attached to the beam. However, the present invention is not limited to the beam, and the same type or similar building material may be used. Also,
Although the lightweight channel steel was used as the lightweight section steel, the invention is not limited to this, and other lightweight sections such as H-section steel and I-section steel may be used. Further, in the above description, the foam fire extinguishing equipment is taken as an example, but the present invention is also applicable to the arrangement of water spray fire extinguishing equipment, open oil tank spray extinguishing equipment, carbon dioxide / halogen fire extinguishing equipment, and the like.

[0016]

As is apparent from the above description, according to the method for arranging fire extinguishing equipment of the present invention, a pipe assembled and connected to a simultaneous release valve and having a head attached thereto is bridged between lightweight steel bars. Since the lightweight section steel is fixed to the ceiling after being integrated, the fire extinguishing equipment integrally assembled on the floor can be arranged on the ceiling. For this reason, it is possible to ensure the safety of the work of arranging the fire extinguishing equipment on the ceiling after the simultaneous opening valve, and to shorten the work time.
