Support-free fully-prefabricated floor slab and mounting method
The support-free fully-prefabricated floor slab comprises a floor slab body and a stress longitudinal bar, the floor slab body is rectangular, the stress longitudinal bar is arranged in the floor slab body in the slab span direction, and the two ends of the stress longitudinal bar penetrate out of the laying edge of the floor slab body and are bent to form U-shaped parts; convex rabbets are formed in the bottoms of the splicing edges of the floor slab bodies, and cup-shaped grooves are formed in the splicing positions of the adjacent floor slab bodies. According to the support-free fully-prefabricated floor slab, the stress longitudinal bars penetrate through the floor slab body in the whole process, the bent U-shaped parts are exposed, and concrete is poured on the structural beams through the U-shaped parts of the stress longitudinal bars, so that stable joint connection is formed between the whole floor slab and the structural beams, and the shear-resistant bearing capacity of beam-slab joints is improved; the complete stress longitudinal bars can reliably transmit the horizontal shearing force of the floors, so that the full-prefabricated floor slab serves as a continuous slab to be applied to industrial high-rise buildings, and the core technical problem that a full-prefabricated slab cannot be applied to buildings with more than 50 floors is solved.
本发明公开了一种免支撑全预制楼板，包括楼板本体和受力纵筋，楼板本体呈矩形，受力纵筋顺着板跨方向布置在楼板本体内部，受力纵筋的两端从楼板本体的搁置边穿出并且折弯形成U形部；楼板本体的拼接边的底部设置有外凸的企口，相邻的楼板本体在拼接处形成杯形槽。本发明的免支撑全预制楼板将受力纵筋全程穿过楼板本体并且外露折弯的U形部，受力纵筋的U形部在结构梁上后浇混凝土，使得整个楼板与结构梁形成稳定的节点连接，提高了梁板节点抗剪承载能力；完整的受力纵筋能够可靠的传递楼层的水平剪力，使得本发明的全预制楼板作为一种连续板应用于工业高层楼房，突破了全预制板不能应用于50层以上建筑的核心技术问题。
