Building foundation pit reinforcing and supporting structure
The invention relates to the technical field of buildings, in particular to a building foundation pit reinforcing and supporting structure. The structure comprises an inclined strut, wherein steel corbels are fixedly connected to the two ends of the inclined strut through bolts, a thickened steel plate is fixedly connected to the ends, away from the inclined strut, of the steel corbels, a plurality of oblong holes allowing anchor bolts to penetrate are evenly formed in the face, facing the inclined strut, of the steel plate, a plurality of rectangular grooves located in one sides of the oblong holes are evenly formed in the face, facing the inclined strut, of the steel plate, liquid storage cylinders arranged in the length direction of the oblong holes are arranged in the rectangular grooves, pistons are slidably installed in the liquid storage cylinders, ejector rods are fixed to the middle positions of the faces, facing guide holes, of the pistons, stop valves communicating with the liquid storage cylinders and used for being connected with oil injection equipment are mounted on the outer surface of one end, close to square supporting blocks, of the liquid storage cylinders. Compared with the prior art, the structure has the following beneficial effects that the probability that the portions, located in the oblong holes, of the anchor bolts are broken due to overlarge load is reduced, and the requirement for the strength of the anchor bolts is lowered.
本发明涉及建筑技术领域，具体的说是一种建筑基坑加固支护结构，包括斜撑，斜撑的两端均通过螺栓固定连接有钢牛腿，钢牛腿远离斜撑的一端固定连接有加厚型钢板，钢板面向斜撑的一面均匀开设有若干个用于穿插锚固螺栓的长圆孔，钢板面向斜撑的一面均匀开设有若干个处于长圆孔一侧的矩形槽，矩形槽内设有沿长圆孔长度方向布置的储液筒，储液筒内滑动安装有活塞，活塞面向导向孔的一面中部位置固定有顶杆，储液筒靠近方形支撑块的一端外表面安装有与储液筒相通的用于连接注油设备的截止阀，与现有技术相比，本发明具有如下有益效果：降低锚固螺栓处于长圆孔内的部位因负荷过大而断裂的概率，降低对锚固螺栓强度的要求。
