一种具有减震功能的装配式钢结构楼梯

Abstract

本实用新型涉及钢结构楼梯技术领域，具体公开了一种具有减震功能的装配式钢结构楼梯，包括上平板和下平板，上平板和下平板之间固定连接有两个前后分布的斜板，两个斜板之间设置有多个L型踏步板，两个斜板的外壁均贯穿开设有多个第一插接孔，多个L型踏步板的前端均贯穿开设有第二插接孔；弹簧减震器内部弹簧储存能量，同时阻尼消耗振动能量，抑制踏步板振动。行人离开后，弹簧释放能量使踏步板顺时针转动复位。弹簧减震器通过弹性变形和耗能机制，有效吸收行人踩踏产生的振动能量，减小噪音与结构共振，显著提升使用舒适性，同时，利用减震机制避免刚性连接导致的应力集中问题，降低节点疲劳损伤风险，进一步提高楼梯的使用安全性。
