Detachable anti-buckling supporting member constrained by bolts

Abstract

The invention discloses a detachable anti-buckling supporting member constrained by bolts. The detachable anti-buckling supporting member constrained by the bolts comprises a peripheral bolt positioning square steel tube, the bolts, a transition clamp plate, springs, reinforced ribbed plates and partial unbonded material layers. The main function of the peripheral bolt positioning square steel tube is to provide positioning for the bolts and support limiting for a core unit. The bolts are mainly used for constraining the core unit, so that the core unit is prevented from being buckled due to compression. The transition clamp plate is used for improving the constraining performance of the bolts. The detachable anti-buckling supporting member constrained by the bolts is obviously different from a traditional anti-buckling supporting member, the manufacturing complex degree is lowered, installing and positioning are easy by using the bolts to carry out constraining, the core unit is easy to center, a gap between the core unit and the constraint is very easy to control, back-and-forth deploying and retracting can be achieved, the manufacturing process of the member is easy to control, meanwhile, only the core unit needs to be replaced, the outer constraint can be reused, and the whole member is economical and convenient.

Description

technical field [0001] The invention relates to an anti-seismic energy-consuming part of an engineering structure, in particular to a buckling-resistant support member which is externally constrained and reusable, and which is simple and convenient to install and limit and has engineering application prospects. It belongs to the structure field of engineering technology. Background technique [0002] The anti-buckling support is mainly composed of three parts: external constraints, core elements and unbonded material (gap). The components are subjected to axial loads by the core elements, and the external constraints mainly provide constraints for the core elements to prevent the core elements from being destabilized under pressure. This allows the member to yield under both tension and compression. The non-bonding material (gap) avoids the contact between the core element and the external constraint, so that the external constraint element does not participate in the axial...

Problems solved by technology

The use of this type of support has the following problems: (1) When the component is damaged, the external constraints cannot be reused, which greatly wastes materials; (2) The gap processing of the non-yielding section of the constraints is more complicated, the production limit is more difficult, and the production monitoring is difficult ; (3) It is difficult to control the gap of the unbonded layer, and the consumption of unbonded materials is large; (4)
