Post-tensioning prestress construction method for flat slab structure
The invention provides a post-tensioning prestress construction method for a flat slab structure. The construction method comprises the steps of entering and rechecking of prestressed material, in-place assembly of steel reinforcement frameworks and cushion blocks, penetrating of prestressed steel strands, concealed acceptance check, handover check and concrete pouring, anchorage device and tensioning equipment installation, tensioning and locking, duct grouting, anchorage device sealing and acceptance of subdivisional work. According to the post-tensioning prestress construction method for the flat slab structure, latticed column bearing supports are adopted as temporary supports, the stress system is clear, and compared with traditional all-round scaffolds, a large amount of materials and labor are saved; and after the prestressed flat slab structure is formed, the requirement for designing appearance modeling and quality requirements are fully met. The formed prestressed flat slab has a smooth surface, the concrete compactness is easy to guarantee, and the surface appearance effect is good.
本发明提供一种无梁楼盖结构后张法预应力施工方法，所述施工方法包括预应力材料进场、复验→绑扎钢筋骨架、垫块到位→穿预应力钢绞线→隐蔽验收、交接检、浇筑混凝土→安装锚具及张拉设备→张拉、锁定→孔道灌浆→封锚具→分项工程验收。本发明的一种无梁楼盖结构后张法预应力施工方法，采用格构柱承重支架作为临时支撑，受力体系明确，比传统的满堂脚手架节约大量的材料和人工；预应力无梁楼盖结构成型后充分满足设计外观造型及质量要求；预应力无梁楼盖成形后表面平整、混凝土密实度容易保证、表面观感效果好。
