Assembly type prestress applying device for foundation pit steel supporting structure
The invention relates to an assembly type prestress applying device for a foundation pit steel supporting structure, and relates to the field of constructional engineering. The assembly type prestress applying device comprises a main connecting main body, an auxiliary connecting main body, a sliding toothed plate meshing locking assembly and a jack. The main connecting main body and the auxiliary connecting main body are combined into an integrated device and can only generate relative displacement in the prestress applying direction, the jack abuts against the auxiliary connecting main body and the main connecting main body to apply prestress, the main connecting main body is provided with a middle sliding toothed plate, the auxiliary connecting main body is provided with an end sliding toothed plate, the two toothed plates form the sliding toothed plate meshing locking assembly and are meshed with each other to achieve locking work of relative positions of the main connecting main body and the auxiliary connecting main body after the prestress is applied, and therefore the prestress is provided for the steel supporting structure. The assembly type prestress applying device is simple in structural component form, and has the advantages of sufficient rigidity and strength, real-time and controllable prestress loading, convenience in mounting and dismounting, easiness in maintenance and overhaul of components, small occupied space volume, capability of being recycled and the like.
本发明为一种用于基坑钢支撑结构的装配式预应力施加装置，涉及建筑工程领域，包括主连接主体、副连接主体、滑动齿板啮合锁止组件和千斤顶。主、副连接主体组合成一体式装置，两者仅可沿施加预应力方向发生相对位移，通过所述的千斤顶分别抵紧副连接主体与主连接主体来施加预应力，所述的主连接主体上设有中滑齿板，所述的副连接主体上设有端滑齿板，两齿板组成滑动齿板啮合锁止组件，相互啮合实现主连接主体和副连接主体间在施加预应力后相对位置的锁止工作，从而实现对钢支撑结构提供预应力。本发明结构构件形式简单，具有足够刚度和强度，预应力加载实时可控，安装和拆卸方便，构件易于维护和检修，占用空间体积小，可重复循环使用等优点。
