Stair structure capable of achieving slope self-resetting and controllable friction energy consumption and construction method of stair structure
The invention provides a slope self-resetting controllable friction energy dissipation stair structure and a construction method thereof.The slope self-resetting controllable friction energy dissipation stair structure comprises a prefabricated rest platform beam plate, the prefabricated rest platform beam plate comprises rest platform beams and a rest platform folded plate, and a prefabricated stair section is arranged between the two rest platform beams; inclined plane self-resetting friction assemblies are arranged at the joints of the prefabricated stair flights and the rest platform beams; the inclined plane self-resetting friction assembly comprises a horizontal friction buffer block and an inclined plane self-resetting friction support which are arranged in parallel, and the inclined plane self-resetting friction support is composed of an upper inclined plane friction block, a lower inclined plane friction block and a pressure spring sliding support which are sequentially penetrated by a connecting screw rod. Self-resetting after sliding of the stair flight is achieved through the inclined face and the self weight, vibration energy is dissipated in combination with the friction face, the anti-seismic performance of stairs and buildings is effectively improved, and compared with other schemes, better anti-seismic performance, reliability, economical efficiency, durability and adaptability are achieved.
本发明提供一种斜面自复位可控摩擦耗能的楼梯结构及其施工方法，包括预制休息平台梁板，所述预制休息平台梁板包括休息平台梁和休息平台折板，两个休息平台梁之间设置有预制梯段，所述预制梯段与休息平台梁连接处设置有斜面自复位摩擦组件；所述斜面自复位摩擦组件包括平行设置的水平摩擦缓冲块和斜面自复位摩擦支座，所述斜面自复位摩擦支座由连接螺杆依次穿过的上斜面摩擦块、下斜面摩擦块和压力弹簧滑动支座组成。本发明采用斜面和自重达成梯段滑动后的自复位，结合摩擦面耗散振动能量，有效提高了楼梯和建筑物的抗震性能，相对于其他方案具有更好的抗震性能、可靠性、经济性、耐久性和适应性。
