Novel double-step buckling restraint steel support
The invention discloses a novel double-step buckling restraint steel support. An axial-extending energy consumption unit, a friction plate, a friction material, face outer restraint units and a fastening unit are included. The energy consumption unit comprises two-end connecting sections and a middle energy consumption section. At least two face outer restraint units are arranged and arranged on the outer side face of the middle energy consumption section. The friction plate is arranged at the radial end portion of the middle energy consumption section and fixedly connected with any two-end connecting sections. The friction material is arranged between the friction plate and the face outer restraint units. The friction plate, the friction material and the face outer restraint units are fastened, locked and restrained through the fastening unit. The one-step friction energy consumption unit is additionally arranged in the novel double-step buckling restraint steel support so that the buckling restraint support can have an energy consumption effect when displacement is very small. A pure steel face outer restraint is adopted for replacing a traditional casing pipe concrete restraint,and the weight of the buckling restraint support is greatly reduced.
本发明公开了一种新型双阶屈曲约束钢支撑，包括轴向延伸的耗能单元、摩擦板、摩擦材料、面外约束单元以及紧固单元；耗能单元包括两端连接段和中间耗能段；所述面外约束单元为至少两个，分别设于中间耗能段的外侧面；所述摩擦板设于中间耗能段径向的端部，且与任一两端连接段固定连接；所述摩擦材料设于摩擦板与面外约束单元之间；紧固单元将摩擦板、摩擦材料以及面外约束单元紧固锁紧约束。本发明增加了一阶摩擦耗能单元，使得屈曲约束支撑在很小的位移时就能发挥耗能效果。采用纯钢面外约束替代传统的套管混凝土约束，大大降低了屈曲约束支撑的重量。
