Abstract
The invention provides a step-bench-separated thin webbed girder type pre-cast stair which comprises a stair bench, step plates and tightening latches. The stair bench is a thin webbed girder type bench. The step plates are L-shaped concrete plates. Two lines of triangular bosses are arranged on the two sides of the upper end of the stair bench. Step plate preassembling platforms are arranged between every two adjacent triangular bosses. The step plates are matched and fixedly connected with the triangular bosses. The pre-cast stair has the advantages that the structure is simple, the design scheme of a step-bench-separated thin webbed girder type scissor stair is put forward, the dead weight of the stair is effectively reduced, and the lifting weight requirement of a frequently-used ordinary tower crane can be met; meanwhile, due to the connection mode of the step plates and bench plates which are separated, operation is easy, and connection is firm.
