A support system for a high-rise fabricated steel structure frame and its construction method

Abstract

A support system for a high-rise fabricated steel structure frame and its construction method, including a connecting plate, a high-strength cable, an anchor plate and a compression spring; the connecting plate is arranged at the two ends of the high-strength cable; on the connecting plate, along the A baffle is connected perpendicular to the direction of the high-strength cables; perforations are opened on the baffle; In the perforation of the plate; the anchor plate is connected on the steel tie rod, near the end; the compression spring is sleeved on the steel tie rod, and is located between the anchor plate and the baffle; Damper; one end of the energy dissipation damper is fixedly connected with the anchor plate, and the other end of the energy dissipation damper is in contact with the baffle. The invention solves the technical problems that the traditional steel support is prone to instability under the reciprocating load, the buckling-resistant support has large residual deformation after an earthquake, is difficult to repair, and the support section is often large, which affects the assembly of window openings and wall panels.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a support system of a high-rise assembled steel structure frame and a construction method thereof. Background technique [0002] The prefabricated steel structure system is widely used because of its high degree of industrialization, fast construction speed, no welding, no pollution on the construction site, and easy control of construction quality. As the height of the building increases, the pure frame structure becomes less and less economical, and the centrally braced or eccentrically braced frame structure becomes a more economical structural form because of its large lateral stiffness and the braces bear most of the horizontal load. Traditional steel supports are prone to instability under reciprocating loads, but the buckling-resistant supports currently used have large residual deformation after earthquakes and are not easy to repair, and the cross-section...
