Meanwhile, in the related art 1, as shown in FIGS. 9 and 10, the case 100 (see FIG. 10) has a bottom surface 110 formed of a quadrangle, and a sidewall (side) is formed at an outer edge of the bottom surface 110. 120 is formed vertically and integrally formed, and the flange 127 is integrally formed at the upper end of the sidewall 120 while being bent in an outward direction.

And the case 100 is installed while the plywood 170 is in close contact with the square shape in the same manner as the bottom surface 110, fastening to the bottom surface 110 while the bolt 112 is coupled to the plywood 170. Thus, the plywood 170 is fixed to the case 100. Reference numerals are 185 for pipes, 116 for clips, 5 for rebar, 2 and 3 amplifiers, 8 for outlets and 9 for distributors.

Referring to the installation procedure and operation of the prior art 1 (100) configured as described above are as follows.

First, in order to easily carry out the riveting operation to the case 100 (see FIG. 10), a plurality of holes are formed at the same interval using drills or the like on the side walls 120 located on both sides of the case 100. In addition, on the case 100, the lower end portion is formed with a plurality of holes at the same interval to couple the pipe 100.

Thereafter, the clip 116 is coupled to the reinforcing bars 5 at the same interval as the holes formed in the side wall 120, and the clip 116 is riveted while closely contacting one end of the clip 116 to the side wall 120. When 116 is fixed to the side wall 120, the case 100 is in a state of being fixed to the reinforcing bar (5).

In addition, the case 100 is installed in the formwork 6.

After the operation, the pipes 185 are coupled to the holes on the case 100 and coupled to the lower ends of the transmission cables, and then the tape is cut to a predetermined size on the entire front of the case 100. It is closed so that concrete does not flow inside by attaching it continuously.

When the concrete is poured in the above state, the concrete is pressed against the rear surface of the case 100 and the side wall 100, and the pressure is acted on by the weight of the concrete being poured to affect the case 100.

Accordingly, the back surface of the case 100 is convex while the middle part is pushed in proportion to the pressure of the concrete to be poured, and the case 100 is different from the original shape.

In this situation, since the widths of the formwork 6 and the case 100 are formed to the same standard (W1), the spacer pin 7 inevitably penetrates the case 100. Therefore, according to the position of the spacer pin (7) installed between the two side mold (6) by drilling a plurality of spacer pin holes on the bottom surface of the case by drilling work to waste the manpower and time in the formwork installation work wall construction There was a problem that delays.

Second, since the outlet 8 is exposed to the bottom surface 110, interference occurs.

Third, since the plywood 170 is installed inside the case to install various devices, the devices are repeatedly attached and detached, so that the plywood state becomes poor, resulting in an unstable installation state.

Fourth, only the amplifier installed in parallel with the floor can be installed, it is impossible to install the device installed in a direction perpendicular to the floor.

Fifth, the installation surface is poor because the middle part is deformed by the pressure delivered to the floor when the concrete is poured.

Sixth, electromagnetic interference occurs between devices, causing a decrease in function.
