High-rise stair sliding support device and construction method

Abstract

The application discloses a high-rise stair sliding support device and a construction method, and relates to the technical field of stair construction. The application comprises a structural beam floor and a stair body. The structural beam floor is provided with a placing groove. The stair body is provided with an end plate. A first groove is formed in the bottom of the inner wall of the placing groove. A second groove is formed in the bottom of the inner wall of the first groove. A vertical part is fixed to the end plate and cooperates with the first groove. A horizontal part is fixed to the bottom surface of the vertical part and cooperates with the second groove. The vertical part and the horizontal part form a buffer block with a T-shaped cross section. A horizontal buffer is arranged on the side of the buffer block, which facilitates buffering in the horizontal direction of the end of the stair body. A longitudinal buffer is arranged on the bottom side of the buffer block, which facilitates buffering in the vertical direction of the end of the stair body. The stair body can be displaced in the horizontal direction and the vertical direction, which effectively prevents the stair from being damaged before the main structure in an earthquake, and prevents the stair from playing a role as an escape passage.
