Large-span steel support multidirectional connecting piece and large-span deep foundation pit support construction method
The invention discloses a large-span steel support multidirectional connecting piece and a large-span deep foundation pit supporting construction method. The large-span steel support multidirectional connecting piece comprises a steel cylinder, joints and rod pieces, wherein the rod pieces are welded at the middle parts of the joints, at least three radially distributed first bolt holes are respectively formed in the two sides of each joint, at least a group of second bolt holes s corresponding to the first bolt holes is arranged on the periphery of the steel cylinder, the periphery of the steel cylinder is vertically connected with at least one joint by a bolt, and the steel cylinder sleeves a steel stand column. The large-span deep foundation pit supporting construction method comprises the following steps: sleeving the steel stand column by using the steel cylinder, lifting down a steel support, marking positions of the bolt holes on the steel cylinder and lifting away the steel support; lifting down the steel support, mounting the bolts according to different support types, pouring concrete in the steel cylinder, and after the concrete pouring is completed, finishing the supporting. According to the large-span steel support multidirectional connecting piece and the large-span deep foundation pit supporting construction method, the distance between the rod pieces and the height of the rod pieces can be regulated in multiple directions and at multiple angles, so that each component can be exchanged and universal; the large-span deep foundation pit supporting construction method can be applied to urban large-span deep foundation pits and abnormal deep foundation pits, so that the technology is improved, and the foundation pit supporting construction is simpler and quicker.
