Prestress assembly type floor slab structure and construction method thereof
The invention provides a prestressed assembly type floor slab structure and a construction method thereof.The construction method comprises the steps that prestressed tendons are arranged between structural beams, the prestressed tendons are stretched for the first time, and the prestressed tendons are anchored in the structural beams of a floor slab support after being stretched; floor precast blocks are hoisted to the installation positions in a block-by-block mode and supported on the prestressed tendons through pre-buried round steel hoisting sticks on the plate side to complete long side supporting, and meanwhile the short sides are fixed through pre-buried steel plates and structural beam angle steel supports; continuing to hoist the residual floor precast blocks, and arranging, supporting and fixing according to design requirements; and after a cast-in-place layer reinforcing mesh is laid, floor cast-in-place layer construction is completed. Therefore, on the premise that the bearing safety is met, partial factory prefabrication of the floor slab is achieved; in the construction process, the floor slab precast blocks and the structural beams are connected into a whole through the prestressed tendons so as to provide enough bearing capacity, construction of a follow-up concrete cast-in-place layer can be met, the floor slab does not need to be temporarily supported additionally, and the bearing capacity of the floor slab is enhanced while prestress is applied to the floor slab.
本申请提供一种预应力装配式楼板结构及其施工方法，其在结构梁之间布设预应力筋，对预应力筋进行初次张拉，张拉完成后锚固于楼板支座结构梁内；将楼板预制块分块吊装至安装位置并通过板侧预埋圆钢吊棍支撑于预应力筋上完成长边支撑，同时在短边通过预埋钢板与结构梁角钢支托固定；继续吊装剩余楼板预制块并按设计要求排布、支撑、固定；铺设现浇层钢筋网后完成楼板现浇层的施工。因此，其在满足承载安全的前提下，实现了楼板的部分工厂预制；在施工过程中，预应力筋将楼板预制块和结构梁连成整体以提供足够的承载力，可以满足后续混凝土现浇层的施工而不需要另行对楼板进行临时支撑，通过在楼板中施加预应力同时也增强了楼板承载能力。
