Description

Electric and communication wiring system box buried under concrete floor}

The present invention relates to a wiring system box for connecting and connecting wires and communication lines (hereinafter simply referred to as 'wires') embedded under a concrete floor. In particular, the present invention relates to a telecommunication line wiring system box for laying concrete floors having a structure capable of adjusting the height of a cover support member for supporting the upper cover of the wiring system box with respect to the height at the top of the box body.

The wires and communication wires that are wired to be buried under the concrete floor (collectively, these two wires are referred to as 'wires') are indoors from the connectors provided in the wiring system box (usually referred to as wiring system box) buried under the concrete floor. It is connected to the side wire. An example of such a wiring system box is disclosed and disclosed in Patent Document 1.

When installing and installing a conventional wiring system box such as Patent Document 1 on a concrete floor, first, parts such as 'outlet fixing plate (4) (16)' are assembled inside the base box (1, referring to the 'box body'). To assemble the box assembly, cover the top opening of the box assembly with a temporary cover so that the concrete does not penetrate into the box when pouring concrete, and then install it at a constant height as a support on the floor surface of the building slab. Then, the concrete is poured around the box assembly at a constant height to fill the top of the box assembly, and then cured. After the concrete has been cured, remove the temporary cover covering the top opening of the body assembly and then attach the top cover to the top opening.

However, when pouring concrete, it is impossible to precisely match the surface of the concrete to be cured by pouring (becoming the floor of the room) to the height of the top of the box assembly. In order to solve this construction problem, conventionally, the box assembly is supported so that the top of the box assembly is slightly below the concrete curing surface, and after the concrete is cured, the cured concrete around the upper opening of the box assembly is partially After removal, an auxiliary ring was put in place to compensate for the height of the upper opening of the buried box assembly.

However, in this way, the method of using the auxiliary ring to match the top height of the wiring system box with the interior floor using the auxiliary ring requires additional repair work to remove the already cured concrete around the top opening of the wiring system box. Therefore, the work is cumbersome, and there is a problem that a skilled worker is required for maintenance work.

In addition, in the case of the conventional system box, the communication connector (C) for connecting the electric connector (C) for electrical plugs and the communication modular jack for connecting the communication modular jack is coupled to the respective fixing brackets (4, 16), and the box body (1) It is installed on the bottom of the chamber (8). As described in Patent Document 1, these wiring connectors C are conventionally embedded in a box assembly on a concrete floor, and when a wiring is connected, an operator puts his hand into the box body buried under the concrete floor and draws it out of the floor. Connect the wiring to the wire, and then put it back into the box to fix it to the box body (1).

As described above, in the prior art, the bracket 4 for connecting the electrical connector and the bracket 16 for connecting the communication line connector must be assembled in the box body 1 in a state in which the box body 1 is inserted. There was a drawback that this was very demanding and cumbersome and took a lot of work time.
