DRS double-rib beam type prefabricated stair
A DRS double-rib beam type prefabricated stair comprises two stair section beams, folded plate type steps and a rest platform, and the folded plate type steps form cantilever ends on the outer sides of the two stair section beams respectively. The folded plate type step comprises a prefabricated concrete stair plate and a folded plate type connecting piece, the stair section beam is connected with the folded angle end of the folded plate type connecting piece, and a clearance is formed between the stair section beam and the folded plate type step. According to the beam type prefabricated stair, the bending moment of the plate is very small, and main stress is applied to the two ribbed beams; the weight of the whole prefabricated structure is further reduced through a connecting piece; meanwhile, the prefabrication process is simpler and more convenient.
一种DRS双肋形梁式预制楼梯，包括两个梯段梁、折板式踏步、休息平台，折板式踏步在两个所述梯段梁外侧分别形成悬挑端；所述折板式踏步包括预制混凝土梯板和折板式连接件，所述梯段梁与所述折板式连接件的折角端连接，并在所述梯段梁与所述折板式踏步之间形成净空。该梁式预制楼梯，板的弯矩非常小，主要受力都在两根肋梁上；并进一步通过连接件，使得整体预制结构的重量更加减轻；同时预制工艺更加简便。
