The invention relates to a prefabricated stair and a construction method thereof, and the scheme comprises the following steps: S100, prefabricating a stair section and an up-down rest platform, and constructing a stair beam; s200, the bottom hoisting supporting rods are vertically arranged and installed between the two ribbed beams, and a hoisting connecting system of the prefabricated floor slab is formed; s300, the rest platform is hoisted to a stair beam which is constructed in advance, after alignment, the hoisting connecting system is dismantled, and the prefabricated assembly type stair hoisting units are fixed through split bolts; s400, after the prefabricated assembly type stair hoisting units which are adjacent up and down are installed every time, joint treatment is conducted between every two adjacent rest platforms; and S500, the step S200 to the step S400 are repeated till construction of all the prefabricated assembly type stair hoisting units is completed, and finally the stair handrail is installed. The hoisting device has the advantages of being reasonable in structure, high in integrity, high in hoisting efficiency and good in installation quality.
本发明涉及预制装配式楼梯及其施工方法，该方案包括以下步骤：S100、预制楼梯段与上下休息平台，并对楼梯梁进行施工；S200、将底部起吊托杆垂直布置安装在两道肋梁之间，组成预制楼板的起吊连接系统；S300、将休息平台吊放至提前施工好的楼梯梁上，对准后，拆除起吊连接系统并采用对拉螺栓固定好预制装配式楼梯吊装单元；S400、每安装好上下相邻的预制装配式楼梯吊装单元后，对相邻两个休息平台之间进行接缝处理；S500、重复步骤S200至S400直至完成所有预制装配式楼梯吊装单元的施工，最后安装楼梯扶手。本申请具有结构合理，整体性强，吊装效率高且安装质量好的优点。
