Abstract

The invention relates to a steel structure connecting piece capable of being tensioned and belongs to the technical field of reinforcing pieces and auxiliary components thereof. The steel structure connecting piece comprises a cylinder body and two pistons arranged in the cylinder body in a sliding fit mode, and the two pistons and the cylinder body form a sealed cavity. Pull rods and springs areconnected to the outer side walls of the pistons, the springs are connected to the inner walls of the cylinder body, and the pull rods penetrate through the cylinder body. Sleeve pieces for fixing steel structures are detachably connected to the ends, arranged outside the cylinder body, of the pull rods, an inner threaded stud is fixedly connected to the bottom of the interior of the cavity, and ahollow telescopic rod is arranged on the top face of the cavity in a penetrating mode. A torsion head is detachably connected to the upper end of the telescopic rod, a hollow outer threaded stud is fixedly connected to the lower end of the telescopic rod, and the outer threaded stud is in threaded connection with the inner threaded stud. According to the technical scheme of the steel structure connecting piece capable of being tensioned, the problems of reliable and rapid mounting and dismounting of two steel structures in the prior art are solved, the magnitude of tension can be adjusted according to the actual requirement, dismounting is flexible and convenient, wide popularization can be achieved, and the practicability is high.

Description

technical field [0001] The present invention belongs to the technical field of reinforcements and their auxiliary components. Background technique [0002] At present, the curtain wall of the building is supported by steel structure, which bears the weight of the curtain wall, wind load, deformation of thermal expansion and contraction, earthquake and other external forces. Usually, the method used at the joints of the steel structure is to weld the steel structure. However, at the nodes of the steel structure, the stress conditions are different. When the steel structure is subjected to a huge external force, internal stress will be generated between the steel structures. If the internal stress is not released, the steel structure will be deformed and worn. [0003] Most of the existing steel structure buildings are connected by welding and fixing. Once formed, it is difficult to disassemble, and the welding process is time-consuming and laborious. This will limit the promo...
