Embodiment 1

[0056] see Figure 1-6 , the reinforcement structure of the curved compression bar in space structure, spherical hinges 4 are arranged at both ends of the curved compression bar 1, including: a constraint member 3 with a rectangular cross section arranged on the outer peripheral side of the curved compression bar 1, the constraint component 3 consists of two lengths It is formed by butt splicing of unequal angle steels 2 that are less than the length of the curved compression bar 1 (the difference between the length of the unequal angle steel 2 and the length of the curved compression bar 1 is less than the outer diameter L1 of the curved compression bar 1), wherein the two unequal The side angle steels 2 all include: a long limb board 2-1 and a short limb board 2-2 arranged vertically in an "L" shape, the two long limb boards 2-1 are arranged oppositely, and the two short limb boards 2-2 are arranged oppositely, And each long limb board 2-1 corresponds to each short limb boar...

Embodiment 2

[0061] see Figure 7-10 , this embodiment is basically the same as Embodiment 1, and the same parts will not be described again. The difference is that the two ends of the curved compression rod 1 near the ball joint 4 are welded and fixed with stiffeners for preventing the bending compression rod 1 from torsion and local buckling. 5. The stiffening rib 5 is arranged along the axial direction of the bending bar 1 and is located in the gap formed by the apex of the constraining member 3 and the outer circumference of the bending bar 1 . A positioning pin 6 is arranged in the middle of the bending pressure bar 1, and a positioning hole is provided at a position corresponding to the positioning pin 6 on the short limb board 2-2, and the positioning pin 6 is plugged and fixed with the positioning hole.

[0062] The present invention also provides two embodiments of the reinforcement method for the curved compression bar of the spatial structure.

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...
