Steel-concrete combined assembly type stair flight
The invention discloses a steel-concrete combined assembly type stair flight. The steel-concrete combined assembly type stair flight comprises a concrete flight and steel pipe oblique beams arranged on the two sides of the concrete flight; the upper end of the concrete flight is fixed to the side face of a stair landing beam or a floor beam in the mode that the upper end of the concrete flight can rotate in the vertical face along the connecting end, and the lower end of the concrete flight is in lap joint with a supporting platform of a stair landing or a floor in the mode that the lower end of the concrete flight can slide in the horizontal length direction of the flight; the steel pipe oblique beams are welded and sealed and filled with water which does not corrode steel after being treated, and after a fire disaster is heated, a steel beam is protected by discharging steam; under the earthquake action, the flight at the lower end can slide in the length direction, the flight at the upper end can freely rotate, the stair flight adapts to interlayer shear deformation of the structure, and the earthquake action effect is effectively prevented from being input into the stair structure; and damping springs are installed on connecting bolts at the upper ends of the flights, the impact effect of the stair flight in the sliding process can be relieved, and self-resetting can be achieved through the springs after the earthquake is finished.
本发明公开了一种钢‑混凝土组合装配式楼梯梯段，包括混凝土梯段和设置于混凝土梯段两侧的钢管斜梁；所述混凝土梯段上端以可沿连接端在竖直面内转动的方式固定于楼梯平台梁或楼面梁侧面，所述混凝土梯段下端以可沿梯段水平长度方向滑动的方式搭接于楼梯平台或楼面的支承平台上；钢管斜梁焊接密封，其内灌装有经处理后不腐蚀钢材的水体，火灾受热后通过排放蒸汽保护钢梁；地震作用下下端梯段能沿长度方向滑动，上端梯段能自由转动，使楼梯梯段适应结构发生的层间剪切变形，有效避免地震作用效应输入楼梯结构；梯段上端的连接螺栓安装有减震弹簧，能减轻楼梯梯段滑动过程的冲击效应，地震结束后通过弹簧又能实现自复位。
