Full-length constrained solderless buckling constrained support

Abstract

The invention discloses a full-length constrained solderless buckling constraint support, which comprises a core plate, a constraint plate and a filling plate. The core plate is sequentially providedwith a first end plate, an energy consumption section and a second end plate in the length direction; the constraint plate comprises a first constraint plate and a second constraint plate, wherein thefirst constraint plate and the second constraint plate are respectively overlapped on the outer sides of two opposite side surfaces of the core plate; the filling plate comprises two first end filling plates and two second end filling plates, the two first end filling plates are respectively overlapped on the outer sides of the two opposite side surfaces of the first end plate and are respectively positioned on the inner sides of the first constraint plate and second constraint plate, and the two second end filling plates are respectively overlapped on the outer sides of the two opposite sidesurfaces of the second end plate and are respectively positioned on the inner sides of the first constraint plate and second constraint plate. The whole length of the support is restrained without welding, the influence of welding seams on materials is eliminated, and the energy consumption capability is strong.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a full-length constrained non-welded buckling constrained support. Background technique [0002] Earthquakes are one of the major natural disasters that threaten the safety of human life and property. In addition to direct damage such as house collapses and casualties, earthquakes can also cause secondary disasters such as fires and pollution, causing immeasurable economic losses. In structural design, bracing as an effective anti-lateral member can greatly improve the anti-lateral stiffness of the structure. Under the action of earthquakes, the traditional central support has the problem of buckling under compression, and it is often necessary to increase the cross-section of the support, which not only increases the earthquake action, but also reduces its economy. Therefore, how to design an energy-dissipating and shock-absorbing system with better energy-dissipating...
