Fabricated energy dissipation joint, construction method and steel frame structure
The invention belongs to the technical field of assembly type frame structures, and provides an assembly type energy dissipation node, a construction method and a steel frame structure, one end of a damper is connected with a middle plate of a first connector, the other end of the damper is connected with a middle plate of a second connector, and the damper is a steel plate with a plurality of long holes formed in the middle in parallel; on the basis of the idea of damage control and deformation concentration, a slit type steel plate damper composed of a plurality of long holes serves as a part of a beam-column connecting section web, a novel shear type damping joint is obtained, in a strong earthquake environment and under the large load effect, the damper with the long holes can meet the deformation requirement, the energy consumption and bearing capacity can be kept, and the damping effect is good. The requirement of anti-seismic performance can be met; meanwhile, the cover plates are arranged on the inner sides of the upper wing and the lower wing, the problem that the safety cover plates cannot be detached when arranged on the upper flange and the lower flange of the steel beam is solved, and replacement and repair of the damper and the cover plates are facilitated.
本发明属于装配式框架结构技术领域，提供了一种装配式耗能节点、施工方法及钢框架结构，阻尼器的一端与所述第一接头的中间板连接，另一端与所述第二接头的中间板连接，且阻尼器为中间位置平行设置有多个长孔的钢板，基于损伤控制和变形集中的思想将多个长孔构成的狭缝式钢板阻尼器作为梁柱连接段腹板的一部分，得到一种新型剪切型阻尼节点，在强震环境下和大荷载作用下，带有多个长孔的阻尼器可以满足变形要求，能够保持耗能与承载能力，能够满足抗震性能的要求；同时，盖板布置在上翼和下翼的内侧，解决了安全盖板布置在钢梁上下翼缘处时无法拆卸的问题，有利于阻尼器及盖板的更换和修复。
