Embodiment Construction

[0035] In order to show the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention. In order to avoid obscuring the essence of the present invention, well-known methods, procedures and procedures are not described in detail.

[0036] Such as Figure 1 to Figure 8 As shown, the cutting hot-rolled angle steel combined cross-shaped buckling restraint support proposed by the present invention includes a core material support member 1, a square steel pipe 2, an upper end plate 3 and a lower end plate 4, and is characterized in that: the core material support member 1 is made of Two hot-rolled angle steels are combined on top of each other, and the cross-section is cross-shaped. The core ma...

Abstract

The invention discloses a cut hot-rolled angle steel combined cross-shaped buckling restrained brace and a manufacturing method thereof and belongs to the technical field of energy dissipation and seismic reduction of civil engineering structures. Two pieces of cutting-formed hot-rolled angle steel are combined into a core material bracing member with the cross-shaped section in a oppositely-pushing mode; a working segment of the core material bracing member is subjected to spot welding, non-working segments of the core material bracing member are connected into a whole through the deep welding technology; after the diagonals of the core material bracing member are embedded in the set positions of a square steel pipe, the square steel pipe is put into an iron frame; the side, welded to a lower end plate, of the square steel pipe is made to face downwards, and a gap between the square steel pipe and the lower end plate is sealed through silica gel so as to avoid mortar leakage; and lightweight aggregate concrete is poured, and after the lightweight aggregate concrete reaches required strength, an upper end plate is mounted in a spot welding mode. The hot-rolled angle steel is adopted as the core material, and thus the problems of temperature stress, residual strain and the like which are caused by the fact that a traditional cross-shaped buckling restrained brace is formed by full-length welding of a steel plate are solved; and a restraining unit is filled with the lightweight aggregate concrete and accordingly has the characteristics of being light, high in strength and thelike, the defect of large weight of the traditional buckling restrained brace is overcome, and a foundation is laid for further application and popularization.

Description

technical field [0001] The invention belongs to the technical field of energy dissipation and shock absorption of civil engineering structures, and in particular relates to a cutting hot-rolled angle steel composite cross-shaped buckling restraint support and a manufacturing method thereof. Background technique [0002] Earthquakes are characterized by strong suddenness and great destructiveness, which require the building structures to consider the anti-seismic performance of structures, especially those built in earthquake-prone areas. With the rapid development of prefabricated houses, the number of steel structure houses is increasing. Most of the existing steel structure systems adopt bending-resistant steel frame system, braced frame structure and double structure system, among which the bending-resistant frame system is the most commonly used, but for high-rise buildings with the bending-resistant frame system, due to the increase in building height, the structure It...
