In the process of forming the padding part 500 of step 5-4, a synthetic resin film is attached to the outer surface of the vertical tube 460 to form a film layer 520, and Styrofoam is attached to the outer surface of the film layer 520 to After the heat insulating layer 540 is formed and the case 560 is coupled to the outer surface of the heat insulating layer 540 , a filler 570 is filled between the inside of the case 560 and the outer surface of the heat insulating layer 540 .

In step 7 (S7), concrete mortar is injected on the base mat 100 so that the base aggregate 250 and the vertical pipe 460 of the sanitary pipe 400 are buried up to the top and cured for a certain time to complete the floor slab. .

In step 8 (S8), after curing the concrete in step 7 (S7), a drainage trap 500 is installed in the opening of the sanitary pipe 400, and waterproof construction and tile flooring are installed on the upper part of the floor slab to provide a drainage trap 500. Perform finishing work by leveling it with the upper part of the

The drain trap 500 is a body 520 in which a pipe connector 522 is formed on the side, a space is formed therein, and an annular locking part 524 having an opening therein is formed; Inserted into the interior of the body 520, a plurality of outlets 542 are formed on the side and lower surface, the strainer 540 is formed with an opening in the upper portion; It is configured to include; a sieve member 560 coupled to the opening of the sieve 540.

Therefore, the sewage may be discharged through the side outlet 542 after passing through the sieve member 560 and collected in the sieve 540 to be drained to the outside through the sanitary pipe 400 .

Meanwhile, as shown in FIGS. 5 to 7 , it is formed inside the filler 570 of the case 560 and includes a heat transfer attenuation unit 40 that blocks heat transfer between the concrete mortar and the case 560 .

Therefore, in winter, the low temperature of the concrete mortar is directly transferred to the sanitary pipe 460 to block the heat transfer so that it does not freeze.

The heat transfer attenuation unit 40 includes a first coupling frame 41 provided in the wall surface 302 of the heat insulation box 300 , and a second coupling frame 42 and a first coupling frame 41 coupled to the first coupling frame. ) and the second coupling frame 42 includes a heat reduction guide portion 43 for guiding to reduce the heat transferred from the outer wall when coupled to each other.

The heat reduction guide part 43 is formed in a plurality of the first coupling frame 41 to guide the heat transferred from the outside of the wall to flow in the inflow guide hole 43a, and the heat introduced into the inflow guide hole 43a. The first coupling frame ( 41) includes a heat absorbing inclined portion 43c provided to be inclined downwardly while being spaced apart from each other.

The inflow guide hole portion 43a is formed in the first coupling frame 41 to be disposed between the reflective collision inclined portions 43b.
