Steel support prestress loading and unloading device for foundation pit supporting engineering
The invention discloses a steel support prestress loading and unloading device for foundation pit supporting engineering. The steel support prestress loading and unloading device comprises supporting steel bodies, a lower bearing plate, stretchable frame pieces, shear stress loading and unloading assemblies and positioning pre-locking assemblies, wherein the supporting steel bodies are evenly arranged on the periphery of the side face of the lower bearing plate, the lower bearing plate is arranged at the bottom of a construction foundation pit in an attached mode, the supporting steel bodies are attached to the inner wall of the side wall of the construction foundation pit through the local deflection effect, the supporting steel bodies support the inner wall of the construction foundation pit in an ejecting mode, the stretchable frame pieces are hinged to the supporting steel bodies through pin shaft pieces, limiting shaft seats used for being connected to the stretchable frame pieces are arranged on the upper end face of the lower bearing plate, a plurality of positioning pre-locking assemblies are evenly arranged on the supporting steel bodies, and the shear stress loading and unloading assembelies are further perpendicularly arranged on the supporting steel bodies in a penetrating mode.
本发明公开了一种基坑支护工程用钢支撑预应力加卸装置，其包括支护钢体、下承压板、伸缩架件、切应力加卸组件以及定位预锁组件，其中，所述下承载压板的侧面四围均匀排设有多个支护钢体，所述下承载压板贴合设置在施工基坑底部，所述支护钢体通过局部偏转作用与施工基坑侧围内壁相贴合，并由所述支护钢体对其进行顶压支护；所述支护钢体上通过销轴件铰接有伸缩架件，且所述下承载压板的上端面设有用于联接所述伸缩架件的限位轴座，所述支护钢体上均匀设置有多个定位预锁组件，所述支护钢体上还垂直贯穿设置有切应力加卸组件。
