AI Technical Summary
When existing reinforced concrete stair sliding supports are used for shock absorption, concrete slurry can easily flow between the sliding support and the staircase, affecting the sliding effect.
An embedded plate and sliding assembly are installed between the reinforced concrete staircase and the reinforced concrete corbel. A sealing assembly consisting of an upper and lower gasket, including first and second rubber gaskets and a compression assembly, is used to achieve a seal by adjusting the tightness of the rubber gaskets with fastening bolts.
This effectively prevents concrete slurry from flowing between the upper and lower pads, ensuring the normal use of the sliding bearing, improving construction efficiency and seismic performance, and providing cushioning protection through polystyrene board.
