The fire extinguishing piping 300 is formed on the upper part of the lower panel 210 so that the fire extinguishing pipe 300 is disposed inside the box body 200 having the U-shaped cross section. The side part 221 of the side member 220 A plurality of pipe through holes 221a are formed at regular intervals in the longitudinal direction so that the connection pipe 400 branched from the fire pipe 300 can be protruded outward through the pipe through hole 221a.

Since the box body 200 of the present invention is constructed so that the upper portion to the lower portion of the box body 200 is embedded in the PC slab 100, the upper fusing portion 222 is formed for fixing the inside of the PC slab 100 made of concrete And the lower coupling portion 223 provides a coupling surface with the lower plate 210 to enable welding, bolt coupling, and the like.

At this time, the sprinkler coupling pipe 600 is fixed to the connecting hole 511 of the long hole, and the sprinkler coupling pipe 600 has a pipe-shaped body 610 having a predetermined length and a hollow interior, A thread 630 is formed on the outer circumferential surface from the engaging protrusion 620 to the other end and the thread 630 is formed on the outer circumferential surface of the engaging protrusion 620 of the body 610 And the other end of the main body 610 is pierced from one side of the vertical plate 510 of the coupling angle 500 to the other side so that the nut 650 is inserted into the main body 610 And is engaged with the coupling angle 500 to be fixed.

A spring 640 is formed between the latching protrusion 620 of the main body 610 and the inner surface of the vertical plate 510 so that the elastic body of the spring 640 can move the body 610 in one direction And when the other end of the body 610 to which the nut 650 is coupled is pulled, the slipper 640 is compressed and it is possible to move in the other direction about the vertical plate 510. In other words, the nut 650 can adjust the length of the body 610 protruding in one direction of the vertical plate 510. In particular, when the sprinkler coupling pipe 600 is engaged with the spring 640 ) Can be compressed and disassembled, so that it is possible to easily combine while converging the error in combining. Particularly, the main body 610 has a plurality of ball springs 611 formed on the inner circumferential surface thereof, so that the connection pipe 400 is inserted into the sprinkler coupling pipe 600, and the ball spring 610 of the sprinkler coupling pipe 600 body 610 611, the coupling tube 400 can be engaged with the coupling groove 410 so as to be seated.

That is, the coupling angle 500 is coupled to the box body 200 at the position of the coupling pipe 400, and the sprinkler coupling pipe 600 fixed to the coupling hole 511 moves along the connection hole 511 of the slot, To be coupled to the tube (400).

Particularly, the outer end of the coupling pipe 200 protruding outside the side plate 220 of the box body 200 and the end of the main body 610 of the sprinkler coupling pipe 600 protruding toward the coupling pipe 300 The sprinkler pipe 600 is pushed from the other side to compress the spring 640 to be positioned at the end of the connection pipe 200 and to decompress the sprinkler pipe 600 again, The coupling pipe 600 moves in the direction of the coupling pipe 400 so that the coupling pipe 400 can be inserted into the sprinkler coupling pipe 600 and coupled.

In this case, if the ball spring 611 of the sprinkler coupling pipe 600 body is not seated in the coupling groove 410, the coupling position of the nut 650 may be adjusted so that the error can be converged .

The coupling angles 500 may be formed on only one side of the box body 200 or may be formed on both sides of the box body 200. A plurality of coupling angles 500 may be moved along the side portions of the box body 200 As shown in FIG.

FIG. 5 is a view illustrating an assembling process of another embodiment of a sprinkler connection box for building fire fighting having a function of reinforcing the tension of a PC slab of the present invention.
