Embodiment Construction

[0033] The present invention is described in detail below in conjunction with accompanying drawing:

[0034] as attached figure 1 And attached figure 2 As shown, the assembly process of the present invention can be completed in the factory. In the factory, the self-resetting mechanism is first assembled on the shell mechanism, and after the tension cable is anchored with an anchor, after the assembly with the energy-dissipating core mechanism is completed, the shell mechanism is fastened with bolts. The upper housing connects the lugs. Then at the construction site, it is only necessary to fasten the protruding wide and narrow connecting plates and the frame with bolts.

[0035] as attached image 3 And attached Figure 4 As shown, the assembly process of the energy-dissipating core mechanism of the present invention is completed in the factory. When assembling, attention should be paid to the matching direction of the fixed channel steel and the steel plate, that is, one...

Abstract

A prefabricated self-resetting energy consumption support comprises an energy consumption core mechanism, a casing mechanism and a self-resetting mechanism, wherein the energy consumption core mechanism comprises a mild steel plate, wide connecting plates, narrow connecting plates and fixing channel steels; the casing mechanism comprises outer channel steels, fixing cable plates and casing connecting ear plates; the self-resetting mechanism comprises cables, anchors and end plates, the cables penetrate cable holes in the fixing cable plates of the casing mechanism and then penetrate cable holes in the end plates at two ends of the casing mechanism, certain prestress is applied and the magnitude of the prestress is determined according to particular situations, and the cables are then anchored by the anchors. The casing mechanism after the cables are tensioned is correspondingly assembled on two sides of the energy consumption core mechanism and fastened by bolts, assembly of the support is completed, the overall machining process of the support is completed in a factory, and the support is assembled to a frame through bolts at the construction site. Under the action of an earthquake, the support can bear most of horizontal shear, and accordingly, the horizontal displacement of the overall structure is reduced, and the repair cost is reduced.

Description

technical field [0001] The invention relates to a self-resetting energy-consuming support, which belongs to the technical field of steel structure application. Background technique [0002] The frame-bracing structure system is one of the most widely used structural systems in high-rise steel structures. Under earthquake action, steel supports bear most of the horizontal shear force and reduce the horizontal displacement of the overall structure. The traditional ordinary support is prone to global and local buckling under the reciprocating action of compression, resulting in its brittle fracture and finally seriously affecting the seismic performance of the overall structure. In the traditional eccentrically It is very difficult to repair later. The anti-buckling support member is an anti-lateral force energy-dissipating shock absorbing device applied in multi-story structures. Under the action of moderate or large earthquakes, the buckling-resisting support member can full...
