Structure of pre-embedded strong and weak electric box in reinforced concrete wall

Abstract

The utility model provides a structure of pre -buried strong and weak electric box in reinforced concrete wall relates to building electrical installation and construction technical field, including hard plastic pre -buried box, the one end of hard plastic pre -buried box is installed with the apron, is equipped with the stud in hard plastic pre -buried box, the outer wall both ends of stud all are connected with the limit piece, the inner wall both sides of hard plastic pre -buried box are equipped with the inner support plate. Adopt prefabricated hard plastic pre -buried box instead of on -the -spot processing wooden mould, and two inner support plates are arranged in hard plastic pre -buried box, and two inner support plates are stably supported to the inner wall of hard plastic pre -buried box through the cooperation of stud and limit piece, and then combined with the angle steel support outside hard plastic pre -buried box, reach the stable support of inside and outside, prevent the phenomenon that hard plastic pre -buried box appears deformation, in addition, the device can prevent concrete from entering hard plastic pre -buried box through the apron with sealing washer.
