Fabricated energy dissipation and shock absorption beam column connecting joint
The invention relates to an assembly type energy dissipation and shock absorption beam column connecting joint which comprises an L-shaped memory alloy connecting plate, a square steel column and an I-shaped steel beam. The square steel columns and the L-shaped memory alloy connecting plates are provided with limiting holes and limiting blocks correspondingly, the limiting effect is high, relative friction sliding and tiny rotation can be generated to absorb earthquake energy during strong earthquakes, and the stability, plastic rotation and energy dissipation and seismic reduction capacity of the beam-column connecting joint are improved. The hemispherical cushion blocks at the two ends of the connecting plate can effectively reduce secondary bending moments of the ends and form an energy consumption and force transmission system with the mini metal energy consumption bar, so that the stress state of the energy consumption and force transmission system is closer to that of a single shaft. The energy dissipation and shock absorption connecting assemblies are obliquely arranged, so that the oblique stress performance and the shock absorption and energy dissipation capacity of the joint can be improved at the same time; the fabricated beam-column connecting joint can be prefabricated in a factory, bolt holes in all the structures are uniform in size, only uniform high-strength bolts need to be used for connection during site construction, and site construction and post-earthquake repair are facilitated.
本发明涉及一种装配式耗能减震梁柱连接节点，包括L型记忆合金连接板、方形钢柱和工字钢梁；方形钢柱和L型记忆合金连接板分别设置限位孔和限位块，其不但有较强的限位作用，强震时还可以发生相对摩擦滑动和微小转动吸收地震能量，提高了梁柱连接节点的稳定性、塑性转动以及耗能减震能力；连接板两端的半球形垫块可以有效减少端部次弯矩，与迷你金属耗能棒形成一个耗能传力系统，使其受力状态更接近于单轴受力；耗能减震连接组件采用斜向设置可同时提高节点斜向受力性能和减震耗能的能力；本发明为装配式梁柱连接节点，可工厂预制且各结构中的螺栓孔统一尺寸，现场施工只需用统一的高强螺栓连接即可，便于现场施工和震后修复。
