Double-layer impact-proof assembled steel structure truss steel bar processing anti-smashing shed

Abstract

The invention relates to a double-layer impact-proof assembled steel structure truss steel bar processing anti-smashing shed. The shed comprises a support unit comprising two square pipe columns and asupport frame, and column legs are arranged at the lower ends of the square pipe columns. The support frame comprises an inter-column truss connected between the upper ends of the two square pipe columns. Three inner trusses are uniformly connected on the other three sides of the upper end of each square pipe column. A rectangular frame composed of four outer trusses is arranged around the outerperiphery of six inner trusses, and each of the inner trusses, the outer trusses and the inter-column truss includes a truss upper chord, a truss lower chord and a truss web. A transverse brace is arranged between the two square pipe columns, and oblique braces are arranged between the side walls of the square pipe columns and the inner trusses. Elastic wooden formworks, steel wire meshes and color steel plates are laid on the upper and lower parts of the support frame, and advertisement boards are laid on the outer side of the outer trusses. The double-layer impact-proof assembled steel structure truss steel bar processing anti-smashing shed provided by the invention is convenient to assemble, stable in structure and high in safety performance.

Description

technical field [0001] The invention relates to the technical field of anti-smashing sheds, in particular to a double-layer anti-collision assembly type steel structure truss reinforcement processing anti-smashing shed. Background technique [0002] In construction projects, tower cranes are often used to transport raw materials such as industrial steel bars, corrugated concrete, and steel pipes. During the peak period on site, multiple tower cranes will be deployed. The tower cranes will cover almost the entire construction area, and basically all steel bar processing areas will be exposed within the coverage of the tower cranes. , considering the windy weather and the finalized protection measures, in response to the requirements of the green construction demonstration site, there is an urgent need for a prefabricated steel structure truss reinforcement processing anti-smashing shed that can resist smashing and will not be overturned by the typhoon, which can be reused, and...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing anti-smashing sheds for steel bar processing can basically only do simple protection, only single-layer color steel plate or steel wire mesh protection, which is not enough to prevent heavy objects such as high-altitude steel blocks from hitting or penetrating. At present, large state-owned enterprises generally use The single-support T-shaped anti-smashing shed is cantilevered at both ends, and all the forces are concentrated on the middle column, which requires a high degree of firmness of the foundation, which is not conducive to flexible installation and dismantling on site, or shifting positions according to different construction stages. Moreover, the single-leg structure does not have sufficient wind resistance. In extreme weather conditions, it is easy to be overturned or damaged. It cannot guarantee the safety, firmness and secondary performance of the anti-smashing shed for steel processing under extreme weather conditions such as typhoons. recycle
