Patent ID: 8581098

Claim:
A socket box, intended to be mounted in a circular opening made in a wall of a block by using a drilling machine equipped with a hole saw, the socket box comprising: a main body made of injected plastic including a rectangular front edge continuing in two semicircular lateral flaps, each of them with a number of pass-through holes intended to retain mortar applied to the wall's surface where the box is mounted and also on the box; each of the semicircular flaps further has a corresponding hole provided with threads receiving a corresponding expansion screw; the main body, through its rear face, incorporates structural reinforcements compatible with a contour of each of the semicircular flaps, such structural reinforcements have a continuity and concordance with upper and lower semicircular wall parts defining, together, a circular profile presenting a measure of a general diameter smaller than a diameter measure presented by the circular opening made in block's wall; from the circular profile a plurality of internal walls of a wall box are developed, which continue in a plurality of rear walls, where a plurality of openings are incorporated to assemble a plurality of conduits; each of the structural reinforcements have an oblique cut reaching proximities of a rear face plan of an edge corresponding to the semicircular flaps, the referred oblique cut coincides with an alignment of the threaded hole, where a corresponding expansion screw is mounted; the oblique cut provided in each of the structural reinforcements creates a corresponding block, whose external face has a retention teeth standard the blocks defined in such a way being subject to lateral displacement with respect to immovable and corresponding structural reinforcements from which they are part due to action of the respective expansion screws; an internal projection is foreseen in the rear wall.
