Cross four-angle-steel type bending constraint support

Abstract

The invention discloses a cross four-angle-steel type bending constraint support, and belongs to the technical field of building structures. The cross four-angle-steel type bending constraint support can preferably transfer axial tension and compression loads, fully exerts the performance of dissipating the seismic energy, can save the steel cost and the production period, and is easy to construct and industrially produce. The cross four-angle-steel type bending constraint support comprises a cross core material, wherein a non-bonding material layer is coated at the outer side of the cross core material; the core core material is arranged in four angle steels; the two ends of the cross core material extend outside the angle steels; friction type high-strength bolt holes are formed in the cross core material outside the angle steels; rectangular steel blocks having through holes are arranged at the outer end of the cross core material between two angle steels; bolts penetrate through the through holes of the rectangular steel blocks and the angle steels at two sides to fixedly connect the rectangular steel blocks with the angle steels to form a constraint mechanism; gaps are left between the cross core material and the angle steels; and stiffened rib plates are fixed at the outer sides of the angle steels.

Description

technical field [0001] The invention belongs to the technical field of building structures, in particular to a cross-shaped quadrangular steel buckling-constrained support, which is suitable for frame structures with buckling-constrained supports. Background technique [0002] Buckling-restrained bracing is gradually popularized and used in buildings with seismic requirements due to its excellent seismic energy dissipation performance. Its specific advantages are as follows: [0003] 1. Buckling-restrained bracing has the characteristics of convenient construction, simple structure, flexible layout, and is suitable for practical engineering applications; [0004] 2. Excellent seismic energy consumption performance, arranged in the frame can effectively consume seismic force, reduce the load of the frame, and improve the overall stability of the structure; [0005] 3. Saving raw materials, while reducing the waste of concrete and steel, it improves the original mechanical pe...

Problems solved by technology

However, the traditional buckling-restrained bracing usually uses a combination of steel and concrete to form peripheral constraints. This kind of component requires high manufacturing precision, self-heavy and difficult construction, and there is a large additional load on the core unit itself, and the manufacturing method is cumbersome, which leads to its popularization. And the scope of use is limited, and the level of industrialization is low
