Fabricated composite floor slab construction method
The invention discloses an assembly type composite floor slab construction method, which comprises the following steps of: during floor slab construction, firstly completing horizontal paving and splicing of prefabricated slabs on a support beam, and then completing concrete pouring of a cast-in-place layer above the prefabricated slabs after a formwork is erected on the lower surfaces of the spliced prefabricated slabs, and is characterized in that after the prefabricated slabs are spliced and the formwork is erected on the lower surfaces, the prefabricated slabs are paved on the lower surfaces of the prefabricated slabs; before the concrete is cast in place, a magnesium phosphate grouting material is poured in the abutted seam, and the magnesium phosphate grouting material contains a magnesium phosphate cementing material. According to the invention, the deformation coordination of the interface bonding strength between the magnesium phosphate grouting material and the concrete composite floor slab can be obviously improved, the rapid splicing construction of the composite floor slab is realized, the floor slab is prevented from cracking, and a new technical approach and technical guarantee are provided for the effective utilization of the magnesium phosphate grouting material in the field of fabricated concrete structure construction.
本发明公开了一种装配式叠合楼板施工方法，楼板施工时先在支撑梁上完成预制板的水平铺装拼接，然后在拼接好的预制板下表面支模后在预制板上方完成现浇层的混凝土浇筑，其特征在于，在预制板拼接好并完成下表面支模之后，在现浇混凝土之前，先在拼缝内浇筑磷酸镁灌浆料，所述磷酸镁灌浆料中包含有磷酸镁胶凝材料。本发明可以显著改善磷酸镁灌浆料与混凝土叠合楼板之间的界面粘结强度的变形协调性，实现叠合楼板的快速拼装施工，避免楼板开裂，为装配式混凝土结构施工领域有效利用磷酸镁灌浆料提供了新的技术途径和技术保障。
