The present invention relates to the field of construction, and more particularly, to efficiently maintain a pipe fitting pipe connecting pipes buried in a wall, and a wall fitting box surrounding the pipe fitting pipe and a pipe fitting pipe using the same more efficiently. It relates to a structure for construction.

In-house piping, such as APTs or houses, is piped to the location of the faucet where the water is used after the raw water pipe passes through the meter. These pipes are installed in the reinforced concrete wall having the strength of the building, especially in the bathroom thickened by the finishing of building materials such as insulation, brick masonry, mortar, tile finishing after the reinforced concrete wall.

In order to connect the above pipe with faucet distributed in several places such as toilet, washing machine, sink, etc. in household, the pipe passing through the meter should be branched several times by a joint pipe (L or T pipe) at a certain position. .

Compared to pipes, these pipes are more likely to leak due to poor quality, such as the quality of pipe connections, foreign material injection, or the construction of pipes and connections.

In particular, in order to protect the pipes in recent years, plastic pipes are used to embed the pipes inside corrugated pipes (CD pipes) larger than the diameter of the pipes, install them together at the time of construction of the rebar in the formwork, and then cast concrete to bury them on the wall. This is implemented a lot.

Therefore, in the event of a leak in the fitting pipe, the finished wall must be dismantled and replaced, which is cumbersome and expensive.
