Jacking steel support quick connection joint and method
The invention relates to a quick connection joint and method for a jacking steel support, flange plates are arranged at two ends of the steel support, the connection joint comprises a hoop, a U-shaped groove is formed in the hoop, the width of the U-shaped groove of the hoop is the same as the thickness of two adjacent butt-joint flange plates, the hoop is formed by splicing a plurality of splicing units, and the splicing units are arranged at two ends of the hoop. Lug plates are arranged at the two ends of each splicing unit, and the lug plates of the adjacent splicing units are fixed through fasteners. The technical problem that in the prior art, mutual connection of steel supports is tedious and infirm is solved. The stress characteristic of the annular steel hoop, namely the principle that a spiral stirrup in a circular reinforced concrete column in building structure engineering reinforces concrete in a core area, is utilized, meanwhile, transverse deformation of the steel support after being pressed is utilized, and therefore it is guaranteed that stress is safer, and due to deformation recovery during installation before stress and unloading after the stress is completed, the safety of the steel support is guaranteed. And the stress between the connecting pieces is recovered to the minimum state, so that the construction mounting and dismounting are convenient.
本发明涉及一种顶升用钢支撑快速连接接头及方法，钢支撑的两端设有法兰盘，连接接头包括内部设有U型槽的抱箍，该抱箍的U型槽的宽度与相邻两个对接的该法兰盘的厚度相同，该抱箍由多个拼接单元相互拼接形成，每个该拼接单元的两端均设有耳板，相邻该拼接单元的耳板通过紧固件固定。本发明解决了现有技术中钢支撑相互连接繁琐且不牢固的技术问题。本发明利用了环形钢抱箍的受力特点，即建筑结构工程中圆形钢筋混凝土柱中的螺旋箍筋对核心区混凝土的增强作用原理，同时利用了钢支撑受压后的横向变形，从而保证了受力更加安全，而在受力前安装和完成后卸载时由于变形恢复，连接件间的受力又恢复到最小状态，从而方便施工安装与拆除。
