Grouting repairable steel support structure for building foundation pit

WANG KECAI

The invention relates to the technical field of building machinery, in particular to a grouting repairable steel supporting structure for a building foundation pit, which comprises a supporting plate main body, the supporting plate main body comprises two first supporting plates and two second supporting plates, the two first supporting plates and the two second supporting plates form an encirclement ring, and concrete is poured into the encirclement ring. A triggering mechanism is arranged at the joint of the first supporting plate and the second supporting plate, is used for detecting the damage position of the supporting plate main body, and comprises a first vertical plate and a second vertical plate. The first vertical plate and the second vertical plate are provided with a first push rod and a second push rod correspondingly, equipment is triggered through deformation of the supporting plate body, fixed-point repairing is carried out according to the bulging position of the supporting plate body, protection can be carried out in time when the supporting plate body is broken, and the fault-tolerant rate and safety of work are increased.

本发明涉及建筑机械技术领域，具体的说是一种建筑基坑用灌浆可修复式钢支撑结构，包括支撑板主体，所述支撑板主体包括两个第一支撑板和两个第二支撑板，且两个第一支撑板和两个第二支撑板形成包围圈，其内部用以浇灌混凝土；触发机构，所述触发机构设置在第一支撑板和第二支撑板的连接处，用于检测支撑板主体的破损位置，所述触发机构包括有第一竖板和第二竖板，所述第一竖板和第二竖板上分别设置有第一推杆和第二推杆利用支撑板主体的变形来触发设备，并根据支撑板主体鼓包的位置进行定点修补，能够在支撑板主体出现破裂时进行及时的保护，增加工作的容错率和安全性。
