Embodiment Construction

[0023] The method of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] In one embodiment of the self-resetting anti-buckling support device provided by the present invention, the self-resetting anti-buckling support device includes an external restraint unit, an inner core and a reset device, the reset device is a return spring member, and the external restraint unit It is used to constrain the bending deformation of the inner core, and the return spring component is used to restore the elongated or shortened inner core to the initial position.

[0025] The present invention adopts the return spring component to produce a reaction force to reset after being deformed by the force of the spring, without applying prestress, and the spring component is cheap, which reduces the cost of the entire anti-buckling support device.

[0026] In some preferred embodiments of the self-resetting anti-buckling device,...

Abstract

The invention relates to a self-reset buckling-restrained brace device. The self-reset buckling-restrained brace device comprises an outer portion constraint unit, an inner core and a reset device, wherein the reset device is a reset spring component, the outer portion constraint unit is used for constraining the bending deformation of the inner core, and the reset spring component is used for recovering the stretching or compression deformation of the inner core. The reset spring component adopted by the self-reset buckling-restrained brace device uses the reactive force generated after a spring is stressed and deformed to conduct reset, a pre-stressing force is not needed to be exerted, on the basis that the good energy-dissipating capacity of a buckling-restrained brace is guaranteed, the residual deformation of the buckling-restrained brace under a large earthquake can be reduced, and the predetermined reset effect is achieved. Compared with a pre-stressing force type self-reset buckling-restrained brace, by means of the self-reset buckling-restrained brace device, the reset functions in stretching and pressing of a brace can be achieved more conveniently. The self-reset buckling-restrained brace device is simple in structure, low in price, convenient to machine and manufacture and convenient for project popularization and application.

Description

technical field [0001] The invention relates to a novel energy-dissipating and shock-absorbing device for a building structure, in particular to a self-resetting anti-buckling support device. Background technique [0002] Traditional steel braces can increase the lateral stiffness and bearing capacity of building structures. However, under the action of strong earthquakes, the braces are prone to overall or local compression buckling, which significantly reduces the seismic performance of the structure. [0003] The anti-buckling support is based on the traditional steel support, and the outer restraint unit is used to restrain the bending deformation of the inner core, so as to realize the full-section yield energy dissipation of the energy-dissipating section of the inner core, and at the same time, no overall buckling occurs. Anti-buckling braces take into account the dual functions of traditional braces and metal dampers, which can effectively reduce the seismic respons...
