Technical Field

The utility model relates to an electrical junction box embedded in a shear wall, in particular to an electrical junction box embedded in a shear wall with freely adjustable exposed width.

Background

In the casting of the concrete shear wall, an illumination lamp and an electric junction box are generally pre-buried, the electric junction box needs to be positioned in a concrete casting template of the wall body before the concrete of the shear wall is cast, the conventional electric junction box is in a square box body, and the exposed surface of the conventional electric junction box is in a plane square shape; when the shear wall is finished, plastering is generally performed on the inner vertical surface of the shear wall, the plastering thickness can be changed along with the large difference of flatness of the wall, and when the shear wall is poured, the positioned electric junction box often has the phenomenon that the outer vertical surface of the line box is lower than a plastering surface layer or protrudes out of the plastering outer vertical surface, so that the line box plastering is uneven in closing-in, poor in overall impression and difficult to install a line box panel.

Disclosure of Invention

The utility model provides an electric junction box that pre-buried exposed width can be adjusted at will in shear force wall, has solved the pre-buried electric junction box of advance positioning exposed width and later stage wall body facade thickness of plastering inconsistent technical problem.

The utility model solves the technical problems by the following technical proposal:

the utility model provides an electric terminal box that pre-buried exposure width can be adjusted at will in shear force wall, the shear force wall that includes concrete placement has pre-buried electric terminal box outer box body in the shear force wall, the activity has cup jointed the interior box body in the outer box body of electric terminal box, be provided with a row of left side recess of horizontal arrangement on the left side inside wall of the outer box body of electric terminal box, be provided with a row of right side recess of horizontal arrangement on the right side inside wall of the outer box body of electric terminal box, be provided with left through-hole on the left side wall of interior box body, left through-hole and a row of left side recess are corresponding to set up, be provided with right through-hole on the right side wall of interior box body, right through-hole and a row of right side recess are corresponding to set up, be provided with the elasticity card silk in the box body in, the left end of elasticity card silk is in one of a row of left side recess after passing left through-hole, the right end top grafting in one of a row of right side recess behind the elasticity card silk.

The left grooves in the left grooves are arranged at equal intervals, and the right grooves in the right grooves are arranged at equal intervals.

The outer box body of the electric junction box is positioned and installed on the wall form before concrete pouring of the shear wall, the inner box body can be sleeved into the outer box body of the electric junction box before post plastering, when plastering of the wall, the inner box body can be pulled according to the specific plastering thickness, so that the exposed vertical face of the outer box body is flush with the plastering wall, and then the outer box body of the electric junction box and the inner box body are fixed together through the elastic clamping wires, so that a panel can be conveniently and rapidly installed, and the construction efficiency is improved.
