Abstract

<P>PROBLEM TO BE SOLVED: To provide a construction method of water spray piping for fire-fighting, for raising the height of a ceiling. <P>SOLUTION: In the construction method of water spray piping for fire-fighting laid underground in floor slab, a water supply pipe of a fire-fighting set is laid underground in the floor slab. Therefore, a space for the height of the ceiling is not required, so that feeling of oppression is not given to a tenant. The construction method dispenses with interior and construction of a ceiling etc., saving costs for interior. Moreover, in the construction method, construction is performed to set in concrete soon after removing the slab, and paint is applied, and thereafter a sprinkler head is quickly replaced, so that a construction period is shortened effectively. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a construction method for firefighting sprinkling pipes, and particularly to a construction method for firefighting sprinkling pipes embedded in a floor slab.

  FIG. 10 is a schematic image of a conventional sprinkling system for firefighting of exposed piping. It is provided with a full threaded rod 2 under the floor slab 1, and an iron water pipe 3 is lifted with an iron ring to expose the exposed piping for firefighting. A watering facility is formed, and then a hole is drilled in the sailing 4 to expose the sprinkler head 5.

  The conventional structure has many drawbacks during the construction, but the water supply pipe 3 of the fire-fighting sprinkler system is disposed under the entire floor slab 1 and needs to hold a construction space of 25 to 30 cm. It can be said that the ceiling height that can be used is reduced, the occupant can easily feel pressure, and is not preferred by the user. For example, although the original ceiling height was 3.5 meters, only a height of 2.9 meters is left, and after finishing the interior of the sailing, the ceiling height will be only 2.8 meters.

  In addition, the entire threaded rod 2 is connected to the pre-embedded screw in the floor slab, and in the construction of the pre-embedded screw, it takes time for one burial work. Since the construction work for lifting the water supply pipe 3 with the ring is performed, a considerable amount of time is required.

  In addition, the cutting of the steel water supply pipe 3 and the assembly of the pipes are relatively inconvenient. The iron water supply pipe 3 is heavy, and the construction person needs the water supply pipe 3 with facilities such as a sawing machine and a threading machine. Since it has to be cut to a proper size and made with screws to connect to the piping, the construction is inconvenient and time consuming.

  In the structure of the water supply pipe 3 suspended by the whole screw rod 2 and the iron ring, there is a drawback that the structure of the water supply pipe 3 is unstable. In particular, when the pipe pressure is measured, the pipe shakes and negatively affects the strength of the structure.

  Furthermore, after removing the slab, pouring concrete into the floor slab 1 and painting it, it is finally possible to carry out fire sprinkling equipment and hydroelectric piping work. Since dirt is easily left and construction disputes tend to occur, construction time corresponding to the construction contents is necessary and troublesome.

  In addition, the fired watering equipment exposed under the floor slab 1 and the disturbed water supply pipe 3 have poor appearance and poor feng shui, so it is usually necessary to add a decorative sailing 4 to the interior. The cost of the building will increase, the ceiling height will be different, and the tenant will feel incompressible, resulting in a design for industrial use that does not match practicality, and it must be improved.

  In view of the drawbacks of the conventional structure, the inventors of the present invention have made research improvements and invented [a construction method of fired water sprinkling pipes embedded in a floor slab], thereby the disadvantages of the conventional structure described above. To solve all.

  That is, the problem to be solved by the [method for constructing fired water sprinkling pipes embedded in floor slabs] of the present invention is to provide a method for constructing fire sprinkling pipes for increasing the ceiling height.

[The construction method of fired water sprinkling pipes embedded in the floor slab] of the present invention includes the following procedures.
1. Assembling the fire fighting set: Combine the joint connection unit, cover and seal in order with the fire fighting set.
2. Fixing the fire fighting set: Place the fire fighting set at a preset position on the slab and fix the cover on the slab based on the construction drawing, and then proceed with the reinforcement of the first stage rebar.
3. Connection of firefighting piping: To connect to the first firefighting piping, connect the water supply pipe to the joint connection unit, and then proceed with the reinforcement of the second stage reinforcement.
4). Pour concrete into the floor slab: Pour concrete into the slab and embed the fire set and fire piping in the concrete.
5. Removing the seal: Remove the slab, work on the concrete on the floor slab, paint, and then remove the seal in the cover directly.
6). Assembling the sprinkler head: The sprinkler head is connected to the connecting side of the joint connection unit, and the construction of the sprinkler pipe for fire fighting is completed.

Based on the above, the advantages of the present invention are summarized as follows.
1. In the [Method of constructing fired water sprinkling pipe embedded in floor slab] of the present invention, the water supply pipe of the fire fighting set is embedded in the floor slab and does not take up the space of the ceiling height, and the occupant feels pressure This is a construction method that eliminates the need for costs, eliminates the need for sailing, increases the willingness to purchase real estate, and has industrial applicability.
2. In the [Method of constructing fired water sprinkling pipe embedded in floor slab] of the present invention, it takes time to embed concrete, and after that, the sprinkler head quickly replaces the seal and trims. The installation and construction of the panel is completed, and the conventional complicated method of implementing a water pipe hung with an all-screw rod and an iron ring can be avoided, the construction time can be effectively saved, and the position of the water pipe can be stabilized.
3. According to the [Method for constructing fired water sprinkling pipes buried in floor slabs] of the present invention, the layout structure of water supply pipes conforming to building fire prevention and fire-related laws and regulations, the appearance of floor slabs is clean, and exposure is disturbed. This is a very simple construction procedure that eliminates contamination of the painted floor slab even when the sprinkler head and trim panel are assembled.

  Other objects, advantages, and originality of the present invention will be described in detail with reference to the following detailed description and related drawings.
