Embedded prestressed carbon fiber self-resetting buckling-restrained brace
The invention provides an embedded prestressed carbon fiber self-resetting buckling-restrained brace, which comprises a core material used for yielding energy consumption in an axial tension or compression state; the restraining body is arranged on the outer side of the core material in a sleeving mode and used for restraining buckling of the core material when the core material is pressed; the inner sleeve is arranged on the outer side of the restraining body in a sleeving mode, two inner sleeve lug plates are arranged on the inner side of one end of the inner sleeve in an up-and-down corresponding mode, and inner sleeve inserting grooves are formed in the other end of the inner sleeve in an up-and-down corresponding mode; the outer side of the inner sleeve is sleeved with the outer sleeve, and an outer sleeve lug plate corresponding to the inner sleeve inserting groove is arranged on the inner side of one end of the outer sleeve; the prestress assembly is provided with sealing plates abutting against the two ends of the outer sleeve, and a prestress part is connected between the two sealing plates; the post-earthquake energy-dissipating and resetting device has the energy-dissipating capacity, meanwhile, the post-earthquake resetting function can be achieved, and the economic and time cost of post-earthquake repairing is remarkably reduced.
本发明提供一种内埋式预应力碳纤维自复位防屈曲支撑，包括：芯材，用于在轴向受拉或受压状态下的屈服耗能；约束体，约束体套装在芯材的外侧，用于约束芯材受压时的屈曲；内套筒，内套筒套装在约束体的外侧，内套筒的一端内侧上下相对应设置有两块内套筒耳板，内套筒的另一端上下相对应开设有内套筒插槽；外套筒，外套筒套装在内套筒的外侧，外套筒的一端内侧设置有与内套筒插槽相对应的外套筒耳板；预应力组件，预应力组件具有与外套筒的两端相抵的封板，两个封板之间连接有预应力件；本发明具有耗能能力，同时能够实现震后复位功能，显著减少震后修复的经济与时间成本。
