A safety support structure for building foundation pit construction

Abstract

The invention discloses a safety support structure for building foundation pit construction, which relates to the field of construction tools. Aiming at the problems that the existing traditional support frame not only has low construction efficiency, but also is difficult to disassemble and recycle, and cannot be used repeatedly, the following scheme is proposed, It includes a folding bracket, a support plate and a telescopic reinforcing rod. The folding bracket includes a bottom strut, a longitudinal strut and a diagonal strut. The bottom strut and the longitudinal strut are connected through a rotating shaft to fold and unfold. One end of the reinforcing rod is connected to the longitudinal strut in rotation, and when the bottom strut and the longitudinal strut are unfolded at 90 degrees, the diagonal strut is turned out and the other end is extended and clamped on the bottom strut. Form a supporting force with the longitudinal struts. The invention can play a good role in supporting the pit foundation, the whole mechanism can stably support the pit foundation, the whole device can be disassembled and folded conveniently, it is convenient to store and recycle, it can be reused, and the construction cost is reduced.

Description

A kind of building foundation pit construction safety support structure technical field The present invention relates to the field of construction tools, in particular to a kind of building foundation pit construction safety support structure. Background technique [0002] The pit foundation is a soil pit excavated at the base design position according to the base elevation and the base plane size. Before excavation, the According to the geological and hydrological data, combined with the conditions of the buildings near the site, the excavation plan is decided, and the waterproof and drainage work is done. Excavation is not deep Those who can use the method of putting side slopes can stabilize the soil slope, and the size of the slope shall be determined according to the relevant construction regulations. Deep excavation and adjacent construction For building construction, the pit foundation wall support method, the shotcrete wall protection method, and even the unde...
