滑动支座楼梯设计与施工技术

Design and Construction in Stairs with Sliding Bearing

将传统楼梯下端支座改成滑动支座,地震时梯段板下端可以在一定范围内伸缩,消弱地震作用下主体结构对楼梯间的影响,从而降低对楼梯的破坏力,延缓楼梯破坏时间,使人员及时撤离。从设计及施工角度分析带滑动支座楼梯的特点及优势。

Through changing the bottom bearing of traditional stair into the sliding bearing,so when the earthquake occurs,the bench plate in wiper can free to stretch within a certain range,weakening the influence of the main structure to the stair under earthquake,reducing the destructive power of the stairs,delaying time of stairs failure to make personnel evacuation in time. The advantages and characteristics of sliding bearings are analyzed from design and construction aspects.
