Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disaster prevention tin rack, and more particularly to in-ceiling piping of a disaster prevention tin rack in a structure.

[Conventional technology and intermediate furnace point]

Conventionally, as shown in Fig. 1, the in-ceiling piping of a disaster prevention sprinkler in a building has been added to the 6e water pipe 2'r ceiling connected to the water supply pipe 1 so as to be parallel to the ceiling.
At a predetermined interval at the bottom of this water pipe 2, one end of the branch pipe B is connected perpendicularly to the water pipe 2, and furthermore, a divine number of water taps 4 are attached to the lower end of this branch pipe 6. It has a three-dimensional structure in which branch pipes 5 are connected in parallel to the water distribution pipe 2.

Therefore, since it is necessary to keep the water pressure applied to each water faucet 4 constant, the inner diameter of the branch pipe 5 connected to the branch pipe 6 is decreased as the distance from the branch pipe 6 increases as shown in FIG. The branch pipe 5 is connected to a water faucet attachment pipe 7 via a joint 6, and the water faucet 4'f is attached to the tip thereof. Here, these branch pipes 5.

The joint 6 and water faucet mounting pipe 7 are threaded connections.

Connection methods such as welding were used.

In addition, the piping methods for water pipes, branch pipes, and branch pipes are mainly processed and assembled on site, and when piping, elbow members are used for L-shaped connections, T-shaped connections, etc. Joints were used to connect pipes with different inner diameters.

However, in order to form a three-dimensional structure as a whole in the ceiling piping 1 of the disaster prevention line cracker of such a conventional structure, a large space is required in the ceiling, and the lift height of the Bonzo above the water becomes long. There is a disadvantage that there is a lot of pressure loss due to breakage, and the total weight increases. Furthermore, the use of a large number of pipes and connecting members with different inner diameters makes the installation process more complicated, and in the case of design changes, etc., it is necessary to start piping from the upper pipe with a larger inner diameter or change the pipe diameter. There are problems such as not being possible.

[Purpose of the invention]

The purpose of the present invention is to solve the above-mentioned conventional drawbacks and problems, and to make it possible to rationalize the piping, occupy a small space in the ceiling, reduce the construction cost, and eliminate the need for design changes. The purpose of the present invention is to provide an easy disaster prevention system such as the following.

[Characteristics of the Invention] A feature of the present invention for achieving such an object is that, in a disaster prevention line cracker of a structure equipped with a water supply source, a water supply pipe, and a water tap, the structure is connected to the water supply pipe and is connected to the water supply pipe. At least one loop-shaped water main pipe arranged approximately parallel to the ceiling of the structure, to which water is supplied, and a loop water main pipe arranged on the same plane as that formed by this loop-shaped water main pipe. At least one water distribution pipe whose both ends are connected to the west e water main pipe at a predetermined interval on the inside, and a divine number of water sprinkling pipes in which a pre-Me water faucet is connected at a predetermined interval to the lower part of this MF water pipe. Relating to a disaster prevention sujirincra equipped with a stopper installation pipe,
.

With this configuration, there is no need to use stepped pipes with different inner diameters, and the amount of water and head can be increased.

[Implementation row]

Next, the present invention will be explained in detail based on examples.

FIGS. 30 to 5 show an embodiment of the in-ceiling piping in the structure of the disaster prevention line crawler according to the present invention.

As shown in Fig. 3, 11 main water distribution pipes 11 connected to the water supply pipe 10 and supplied with water from a water supply source are arranged in a substantially parallel loop shape on the ceiling of the structure. . A plurality of water pipes 12 are located on the same plane as the loop-shaped main water pipe 11, inside the loop, and have both ends joined to the water distribution pipe c#11.
They are backwashed and joined at predetermined intervals. This water pipe 12
The nominal diameter of the main water pipe 11 is approximately -. For example, when the main water pipe 11 is 80-, it is about 12 C water pipes and 40P. The length of the main water pipe 11 and the water pipe 12 which are cut in this case is preferably about 5 m to 8 m in this embodiment.

In addition, a water faucet installation pipe 16 is provided below the water pipe 12 at a predetermined interval, and the water faucet installation pipe 16 is double-jointed to the lower part of the water pipe 12. (see Figure 5) is added. The inner diameter of this water faucet mounting pipe 16 is
If the water pipes 12 are lined up approximately 20 to 25 hours apart.

With the above configuration, a double loop is formed, one formed by the main water pipe 11 and another loop formed by the water pipe 12 and a part of the main water pipe 11. That will happen.

Next, let's talk about the assembly process of this disaster prevention line cracker. I will explain.

Figure 4a, 1] shows the main water pipe 11 and the water pipe 12 shown in
This is what is shown. 11 main water pipes and 12 water pipes,
Both are formed by welding a fixed length to a predetermined length at two work sites.

In other words, the west? A loop of the water main pipe 11 is formed by joining on the ground at the main site, and this is suspended using a no-hydro tower and installed on the ceiling side. Next, the unit of water pipe 12 and water tap 16 that were joined at the factory is suspended in a hydro tower, placed inside the loose part of the main water pipe 11, and joined to the main water pipe 11. Then, the units are joined in sequence in this manner repeatedly to form a shape as shown in FIG. 3.

In addition, when installing the water distribution main pipe 11 etc. in a curved shape, without using an elbow member etc., the water distribution main pipe 11 etc. is bent in advance with a hydraulic pender at the factory, and the bent pipe 11 etc. is
Water main pipes, etc. and straight water distribution main pipes, etc. will be welded at the viewing area.

14 parts of the main water pipe 11 that are connected to the water pipe 12,
This part is rounded out at the factory, and this part and one end of the water pipe 12 are welded together in a VC9 shape.

On the other hand, the water pipe 12 and the 16 water faucet mounting pipes are welded at the factory, and 15 parts of the water pipe 12 that are joined to the water faucet mounting pipe 16 are welded at the factory. One end of the water faucet mounting pipe 16 is a V-shaped one (to be welded).

Next, water pressure tests, etc. are carried out for 1 hour, and after the completion of the work, work is carried out such as installing the ceiling base, ceiling covering, head sealing force, etc., and the construction is completed.

FIG. 5 shows the joint portion of the main water pipe 11 and the water pipe 12 in the ceiling piping of the Sujirinkura structure.

A water distribution pipe 12 with the upper end of a water faucet installation pipe 13 joined to the lower part of the rounded portion 14 of the main water pipe 11 arranged in a loop shape horizontally with respect to the ceiling 16 is connected to the ceiling 16. A water faucet 17 is attached to the lower end of the faucet attachment pipe 16, which is welded horizontally to the water faucet and is twisted.

Sprinkler construction constructed as above
Inside? The pipe is the main water pipe 11 Yoshinishi [1 water pipe 12's ゛1゛1
Attach the joint part of the shape, the water pipe 12 and the water tap. 13
The 'r-shaped joint part of the pipe is connected by beading process, PA connection and edge processing, and the bent # part of the water main pipe 11, etc. is bent with a bender, and the container pipe is made using a standard length of a certain length. The joint part,
Since welding is performed without using joints, the amount of waste used for piping is greatly reduced. At the same time, water pressure loss is also reduced. '1. As a result, almost equal water pressure can be applied to the plurality of water faucets 17 added to the plurality of water faucet attachment pipes 16.

Further, the 19 water main pipes 11 are arranged in a loop, and both ends of the water pipes 12 are successively mounted on the same surface -1- as the surface formed by the loop-shaped main water pipes 11 at a predetermined interval. Therefore, the task becomes easy. Moreover, the ceiling piping of the Sujirinkura structure is constructed by a large loop formed by the main water distribution pipe 11 and a plurality of double loops formed by joining the water distribution pipe 11 to the water main pipe 11. It will be deployed horizontally to the ceiling. As a result, water can be supplied by going around, the height of water from the water supply source can be shortened, and the pressure on the water tap 17 can be made almost uniform.

In the example, multiple water pipes were attached to one loop-shaped main water pipe, but in the ceiling piping of the Sujirinkura structure, the large loop formed by the main water pipes constitutes one structure. Therefore, it is possible to arrange a plurality of water main pipes forming one structural unit depending on the scale of the clay field to be piped. It is also possible to provide a number of water supply pipes in the form of loops that supply water from the existing water supply source.

In addition, the size and shape of the large loop formed by the main water distribution pipe does not matter, depending on the shape of the location where the piping is to be done.
Depending on the shape of the large loop formed by the main water distribution pipes, the size and shape of the loop formed by the water distribution pipes to be joined are also not limited.

8- Next, if the water faucet has the specified water flow rate, the nominal diameter of the water pipe does not necessarily need to be + approximately - of the west 1 water main pipe, and the nominal diameter of the branch pipe The diameter does not necessarily have to be approximately - of the water pipe. The material of the cut West 11 water main pipe, 1 water pipe, etc. does not matter, such as aluminum or synthetic resin.

Next, if we compare the total number of piping materials and the number of working personnel (11 pipes into the ceiling of the conventional structure and the ceiling piping of the structure according to the present invention), the building area is 175B6n?,!
On a scale of ffi area of 36,526m and number of water faucets: 056, according to a certain company's estimate data, there are 1' pipes in the ceiling of a conventional structure! ll' Tubing material total weight 27.5
According to the ceiling piping of the structure according to the present invention, the piping work requires 293 workers per 1000 water taps and 10.7 workers per 1 total piping material weight. Italy '25.6+, 166.4 workers per 1000 water taps (76.8 factory workers).

The total number of workers required for each 11 piping materials was 6.5 (3 factory staff, 3.5 field staff).

As is clear from the following description, the disaster prevention sprinkler according to the present invention is a disaster prevention sprinkler VC of a structure equipped with a water supply source, a water supply pipe, and a water tap. Discharge sand into the water supply pipe,
11 At least one loop-shaped main water distribution pipe arranged approximately parallel to the electrostatic 1 structure in which water is supplied from the water supply source is formed by this loop-shaped main water distribution pipe. Ai';fi',ll]+' A small, ancient water pipe with both ends connected to the water main pipe and the lower part of this water pipe. Since it is equipped with an initial number of water faucet extension pipes for attaching the water faucets that have been joined at a predetermined interval (r), piping can be done using only several types of pipes with different inner diameters. You can easily adapt to changes in the structure of the trench.
The implementation cost will also be low.

Furthermore, it occupies less space within the ceiling.
