Anti-seismic sliding support for concrete stairs
The invention relates to a concrete stair anti-seismic sliding support, which belongs to the technical field of stair anti-seismic, and comprises a stair plate, and an upper platform and a lower platform at two ends of the stair plate, the stair plate is in pouring connection with the upper platform, and a sliding groove is formed in one side, close to the stair plate, of the lower platform, and the stair plate is in sliding connection with the sliding groove; the first U-shaped elastic strips are evenly arranged on the side wall of the sliding groove, and the second U-shaped elastic strips are arranged between the adjacent first U-shaped elastic strips. The first U-shaped elastic strip and the second U-shaped elastic strip form a double-corrugated buffer strip, an upper platform and a lower platform of a building can be separated from a stair, the first U-shaped elastic strip and the second U-shaped elastic strip which are arranged in a staggered mode are used in cooperation with the sliding cushion layer, and horizontal extrusion force of the stair to the sliding support is transmitted to the upper side and the lower side; the first U-shaped elastic strip and the second U-shaped elastic strip are prevented from being excessively extruded; the sliding support is high in stability, good in anti-seismic effect, high in practicability and worthy of popularization.
本发明涉及一种混凝土楼梯抗震滑动支座，属于楼梯防震技术领域，包括楼梯板以及其两端的上平台、下平台，楼梯板与上平台浇筑连接，还包括滑动凹槽开设在下平台靠近楼梯板的一侧，楼梯板与滑动凹槽滑动连接；多个第一U型弹性条分别均匀设置在滑动凹槽的侧壁上，多个第二U型弹性条分别设置在相邻的第一U型弹性条之间；本发明通过第一U型弹性条、第二U型弹性条构成双波纹缓冲带，不仅能够将建筑物的上下平台与楼梯进行隔开，交错设置的第一U型弹性条、第二U型弹性条与滑动垫层配合使用，将楼梯对滑动支座的水平挤压力向上下两侧进行传递，避免对第一、二U型弹性条进行过度挤压；本发明的滑动支座稳定高，抗震效果好，实用性强，值得推广。
