Prefabricated reinforced concrete shockproof stair and construction method
The invention discloses a prefabricated reinforced concrete shockproof stair and a construction method. The stair is composed of stair section boards, platform supporting components, an outer side platform beam, an inner side platform beam, a supporting beam, a Teflon board, sealing strips, an inverted-L-shaped board, a framework beam, edge columns and middle columns, wherein the step end of the stair section boards is fixed on the supporting beam; the platform end of the stair section boards are connected to the outer side platform beam and the inner side platform beam in an abutting mode; the protrusive end of the inverted-L-shaped board is fixed on the supporting beam; the plane end of the inverted-L-shaped board is fixed on the framework beam; the platform supporting components are fixed on the edge columns and the middle columns; the inner side platform beam and the supporting beam are fixed on the platform supporting components. The beams and the columns in the stair components are fixedly connected in a groove and tongue mode. In the stair construction process, the components are welded, after the outer side platform beam and the inner side platform beam are fixed, the Teflon board is stuck to the upper surface, and therefore the stair section boards can slide relative to the outer side platform beam and the inner side platform beam. The prefabricated reinforced concrete shockproof stair can reduce the earthquake damage when an earthquake occurs, and ensures safety.
