Fabricated buckling-restrained brace

Abstract

The invention discloses an fabricated buckling-restrained brace. The fabricated buckling-restrained brace comprises an inner supporting structure and a restraining assembly, wherein the inner supporting structure comprises a supporting inner core, a filling part and a non-adhesive layer; the restraining assembly comprises an external restraining layer and fastening parts, the outer restraining layer wraps the outer part of the supporting inner core, the filling part is arranged between the outer restraining layer and the supporting inner core, the non-adhesive layer is arranged between the supporting inner core and the filling part, the number of the fastening parts is multiple, and the multiple fastening parts are detachably fixed to the outer side of the outer restraining layer, the filling part and the non- adhesive layer can be directly arranged on the outer side of the supporting inner core, the supporting inner core is wrapped with the non-adhesive layer through the outer restraining layer, mortar and concrete are replaced through the filling part, field assembly and disassembly can be achieved, installation is more convenient, installation can be completed without large machines, and the construction efficiency can be improved.

Description

technical field [0001] The invention relates to the field of building anti-seismic structures, in particular to a buckling-resistant energy-dissipating support. Background technique [0002] my country's geological structure is complex, the seismic fault zone is well developed, and the seismic activity range is wide, the intensity is high, and the frequency is high. Improving the earthquake resistance of building structures is the most fundamental and effective measure for disaster prevention and mitigation. In the field of civil engineering, energy-dissipating shock absorption technology has been widely used in engineering structures, among which buckling-resistant energy-dissipating braces are one of the most common energy-dissipating devices. The support can fully yield under the action of tension and compression, the hysteresis curve is stable and full, and has good hysteresis energy dissipation performance. [0003] At present, the buckling-restrained braces produced a...

Problems solved by technology

[0004] 1) Although the strength of mild steel is very high, it has the defects of weak deformation ability and high quality, and it does not have reset ability;

[0005] 2) Mortar or concrete is mostly poured between the steel casing and the core material, so that the anti-buckling energy-dissipating support steel casing and the core material can only be cast-in-place, and cannot be disassembled and assembled at any time;

[0006] 3) Most of the existing buckling-resistant energy-dissipating supports use steel sleeves as external restraint members, and the core material is made of low-yield steel. It is bent due to its own weight, and it is not easy to transport and carry
