Construction method for implementing hoisting through floor or roof of building structure

The invention discloses a construction method for implementing hoisting through a floor or a roof of a building structure, and belongs to the technical field of building construction. The problems that an existing tower hoist and an existing homemade roof/floor hoist are poor in economical efficiency and large in construction difficulty and effective utilization of an automobile crane is limited are solved. The construction method comprises the following steps that supporting legs of the automobile crane are arranged at the centers of structural columns of the floor or the roof of the building structure for implementing hoisting operation. 本发明的利用建筑结构的楼面或屋面实施吊装的施工方法，涉及建筑施工技术领域。针对现有塔吊及自制屋/楼面吊经济性差或实施难度大，而汽车起重机的有效利用又受到限制的问题。施工方法如下：根据所选汽车起重机的型号和结构图纸，将所述汽车起重机的支腿布置在所述建筑结构楼面或屋面的结构柱的中心实施吊装作业。
