The present invention relates to a close contact structure of a buried distribution box for a multi-family housing, which is used to fix an embedded distribution box for drawing out an electric wire drawn out of a wire guide tube embedded in a reinforced concrete wall to a reinforcing bar. By freeing vertical and horizontal rotation to the embedded distribution box by the spring, if the inner surface of the formwork and the embedded distribution box cannot be parallel due to construction errors, the embedded distribution box should be in close contact with the inner surface of the formwork. The present invention relates to a close contact structure of a buried distribution box for a multi-family house, which prevents concrete from penetrating into the buried distribution box during concrete pouring work.

In general, electric wires are buried inside the walls of multi-unit houses that are constructed of reinforced concrete, and they are drawn out of the walls before the concrete formwork is carried out. It is possible to install switches, outlets, etc. in the embedded distribution box exposed out of the wall by pouring concrete, curing it, and removing formwork in close contact with the inner side of the wall.

In this way, in order to adhere the embedded distribution box to the inner surface of the formwork, the reinforcement is conventionally coupled to the embedded distribution box using bolts and nuts, and the reinforcing material is bound to the reinforcing bar reinforced inside the wall using the binding wire. One side of the auxiliary reinforcing bars, which were installed or of the same length as the thickness of the concrete wall, was welded to the side or the rear of the embedded distribution box, and the other side of the auxiliary reinforcing bars was welded to the reinforcing bars.

However, it is easy to use reinforcement, but since the embedded distribution box cannot move after being installed on the reinforcing bars, if an error occurs when installing the formwork, a gap occurs between the formwork and the embedded distribution box, so that concrete is embedded when concrete is poured. There was a problem that the embedded distribution box was buried inside the wall by penetrating into the inside of the mold distribution box.In the indoor wiring work, the worker had to crush the concrete to expose the embedded embedded distribution box to the outside. There was a problem of cracking.

In addition, when the embedded distribution box protrudes from the inner side of the formwork, the embedded distribution box must be hit with the inner side of the form by hitting the embedded distribution box with a hammer, so that the embedded distribution box is damaged in this process.

Since the installation by welding is constructed by welding to the rebar in consideration of the thickness of the concrete wall, it is relatively consistent with the inner surface of the formwork, but the position of the embedded distribution box when the form is inclined or the thickness is changed by the construction error. Not only does it have to be priced with a hammer to change the pressure, but also has the inconvenience of mobilizing equipment for welding.

In order to solve this problem, Korean Patent Registration No. 10-0611811 (registered on August 4, 2006, name: Variable binding device of a distribution terminal box) has been proposed. As shown in FIGS. 1 and 2, the linear guide parts 11a and 11b are formed on the left and right sides of the fixed plate 10 bent in a “U” shape, and the linear guide parts 11a are formed. Clamps (13a) and (13b) having a cross-sectional shape of the "C" shape is formed at the end of the (11b) to the reinforcing bars (12a) (12b) vertically located on the left and right sides so that the fixing plate 10 is reinforced It is supported by (12a) (12b), the linear guide in the form of a square pipe to the left and right sides of the base plate (15) for supporting the embedded distribution box 14, sliding to the linear guide portion (11a) (11b). The parts 16a and 16b were formed, and the spring 17a which pushes the embedded distribution box 14 toward the inner side of the formwork 18 between the fixed plate 10 and the base plate 15 ( 17b) was intervened.

However, such a conventional "variable binding device of a distribution terminal box" is a buried type distribution box 14 is formed when the front portion of the buried distribution box 14 and the inner surface 18a of the formwork 18 are not parallel. 18 is not completely in contact with the inner surface 18a, and a gap T is formed at one side, and concrete enters the inside of the embedded distribution box 14 during the concrete pouring operation. There was a problem of completely buried in concrete.

The present invention has been made to solve the above problems, the purpose is that the embedded distribution box is in close contact with the inner surface of the formwork even when the inner surface of the formwork and the embedded distribution box does not form a certain interval due to construction errors. By preventing the gap between the buried distribution box and the formwork so as to provide a close structure of the buried distribution box for apartment housing to prevent the concrete from penetrating into the interior of the buried distribution box.
