Staged yield energy dissipation shear wall connection damper with self-resetting capability
The invention relates to the technical field of buildings, and discloses a staged yield energy dissipation shear wall connection damper with self-resetting capability, which comprises an embedded part, a shear yield energy dissipation damping part and a tension-compression yield energy dissipation damping part, the embedded part comprises embedded channel steel and embedded H-shaped steel, an anchor bolt is welded on the embedded part, and a bolt hole is pre-machined on the embedded part; the shear yield energy dissipation damping piece comprises connecting channel steel and a special-shaped energy dissipation steel plate which are welded into a whole. The shear energy dissipation damping part is connected with the pre-buried H-shaped steel through bolts, and staged yield energy dissipation is achieved through yield of the springs and the special-shaped energy dissipation steel plates. The tension-compression yield energy dissipation damping part mainly comprises a first yield energy dissipation damping part and a second yield energy dissipation damping part, and the first yield energy dissipation damping part is connected with the second yield energy dissipation damping part; the first yield energy dissipation damping piece is connected with the embedded channel steel through a low-carbon steel rod, and the staged yield energy dissipation effect can be achieved when the same earthquake occurs; after an earthquake is dissipated, the spring units installed in the shear yield energy dissipation damping piece and the tension-compression yield energy dissipation damping piece can achieve the self-resetting function. The performance of the concrete and the performance of the steel can be effectively exerted, the bearing capacity and the energy dissipation capacity are achieved, the construction quality can be guaranteed through full-assembly type connection, and the construction efficiency is greatly improved.
本发明涉及建筑技术领域，公开了一种具有自复位能力的分阶段屈服耗能剪力墙连接阻尼器，其包括预埋件、剪切屈服耗能阻尼件、拉压屈服耗能阻尼件；预埋件包括预埋槽钢和预埋H型钢，并焊有锚栓、预加工有螺栓孔；剪切屈服耗能阻尼件包括连接槽钢和异形耗能钢板，两者焊接组成整体；剪切耗能阻尼件通过螺栓与预埋H型钢连接，利用弹簧、异形耗能钢板屈服实现分阶段屈服耗能；拉压屈服耗能阻尼件主要包括第一屈服耗能阻尼件和第二屈服耗能阻尼件两部分，第一屈服耗能阻尼件和第二屈服耗能阻尼件连接；第一屈服耗能阻尼件通过低碳钢棒与预埋槽钢连接，同样的地震发生时可实现分阶段屈服耗能效果；地震消散后安装在剪切屈服耗能阻尼件和拉压屈服耗能阻尼件中的弹簧单元可实现自复位功能。本发明能有效发挥混凝土与钢两种材料的性能，兼具承载和耗能能力，且全装配式连接可以保证施工质量、大幅提高施工效率。
