Reinforcing structure and reinforcing method of spatial structure bending compression bar

Abstract

The invention discloses a reinforcing structure and a reinforcing method of a spatial structure bending compression bar. The reinforcing structure of the spatial structure bending compression bar comprises a restraining component which is arranged on the peripheral side of the bending compression bar and has a rectangular cross section. The restraining component is formed by two unequal-angle steel pieces shorter than the bending compression bar in a butt joint splicing mode. Each unequal-angle steel piece comprise a long-limb plate and a short-limb plate which are perpendicularly arranged inan L shape. The two long-limb plates are oppositely arranged, the two short-limb plates are oppositely arranged, each long-limb plate corresponds to the corresponding short-limb plate and is fixedly welded, and the inner sides of the long-limb plates and the inner sides of the short-limb plates are in butt joint with the outer wall surface of the bending compression bar. By means of the reinforcing structure and the reinforcing method, the problems that the sizes of constraint parts are numerous and matching is difficult due to existence of initial bending of the compression bar are solved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, and more specifically relates to a reinforcement structure and a reinforcement method of a space structure curved compression bar. Background technique [0002] At present, people have higher and higher requirements for the unshielded space of large buildings, and it is difficult for the original structural form to meet these requirements. The large-span space structure is currently the fastest-growing structure type, and the development status of the space structure technology as its core is one of the important symbols representing a country's architectural technology level. [0003] If the failure of the space structure caused by unqualified construction quality is neglected, then when the span of the space structure is small, the failure mode of the structure is mainly manifested in the strength failure caused by the sudden failure of the rods at the support; The failure mode is us...
