Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a concrete building such as an apartment or a condominium, and more particularly to a technique for constructing a building having a large number of water rooms such as bathrooms and toilets.

[0002]

2. Description of the Related Art Conventionally, a concrete building for a general house such as an apartment or a condominium is provided with at least one bathroom and one toilet in one section. In these, after the building is built, the slab of each floor and the outer wall of the building are built, then the bathroom unit and toilet room unit are disassembled and carried in, and water supply pipes, drain pipes, Pipework for sewage pipes, etc., and power supply wire construction were performed, and each bathroom unit was assembled and waterproofed. Even if these watering rooms are constructed using assembling units, there are many on-site plumbing work, power supply wire work, and water leakage prevention work after assembling, and since these are performed by special technicians, work schedules are required This is a time-consuming and time-consuming task. In addition, since the work is performed on site, piping and wiring errors increase, resulting in inaccurate construction, and water leakage often occurs.

[0003]

DISCLOSURE OF THE INVENTION The present invention solves these conventional problems, greatly reduces the on-site work related to a water circulating room at the site, and reduces the number of construction errors and water leakage errors and shortens the construction period. It is an object of the present invention to provide a method of assembling a building with a water plunger, which is capable of achieving an accurate finish and greatly reducing construction costs.

[0004]

Means for Solving the Problems The structure of the present invention which has solved the above problems is as follows: 1) Externally connecting a water supply pipe and a wiring work of a power supply wire to a room frame of a water supply room such as a bathroom or a toilet room. The ceiling and floor members, outer wall material and opening fittings are attached to the room skeleton, the indoor water lining product is installed inside the room, and the assembled water basin with the waterproof wall material of the interior is installed first. After assembling at the factory, constructing the frame of the building on the site, placing the slab, transporting the above-mentioned water room and installing it at the predetermined position of the slab, connecting the water piping and power supply wires externally ,
Reinforcement using part of the outer wall and the ceiling wall of the water circulating room part as a formwork, pour concrete into the formwork and the room ceiling part to construct a vertical wall and a slab, The exterior of the circling chamber is covered with the outer wall of the circulating chamber to complete the circulating chamber, and the building is constructed on the next floor by constructing the circulating chamber and slab casting in the same manner. In the pre-assembly construction method.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The material and structure of the ceiling member and the side member which are also used as the mold of the water basin of the present invention are selected so as to be waterproof and water-resistant and have sufficient strength. Rust-proofed steel is used for the body of the water circulating room, and a plastic unit interior room is used as the interior of the water circulating room because of its excellent waterproofness and ease of assembly. After that, install the indoor toilet bowl, hand-washing sink, tank, bathtub, etc.
It is preferable that the bathroom and the toilet are divided into one section and incorporated together because the construction and the construction are simplified.
