Vertical construction joint formwork structure of flat concrete structure and construction method
The invention discloses a slab concrete structure vertical construction joint formwork structure and a construction method. The slab concrete structure vertical construction joint formwork structure comprises a steel bar grid and an air bag. The steel bar grids comprise a top steel bar grid and a bottom steel bar grid which are arranged at the position of the slab concrete structure to be constructed; after the air bags are inflated, the upper ends of the air bags are clamped by the steel bar grid at the top, and the lower ends of the air bags are clamped by the steel bar grid at the bottom; side pressure generated during concrete pouring is borne through the rigidity formed by extrusion of the inflatable air bags and the supporting effect of the steel bar grids on the inflatable air bags. The method is simple and flexible, only the air bags need to be placed in the steel bar grids at the construction joints and are filled with air, concrete is prevented from overflowing in the pouring process, the problem that the construction joint formworks are difficult to support and disassemble during flat plate concrete structure construction is well solved, the construction efficiency of the construction joint formworks is improved, the construction progress is optimized, and the construction cost is reduced.
本发明公开了一种平板混凝土结构竖向施工缝模板结构及施工方法，包括钢筋网格和气囊；所述钢筋网格包括设于待施工平板混凝土结构处的顶部钢筋网格和底部钢筋网格；所述的气囊竖向置于钢筋网格内，气囊充气后上端被顶部钢筋网格夹持、下端被底部钢筋网格夹持；利用充气气囊挤压形成的刚度及钢筋网格对充气气囊的支撑作用承受混凝土浇筑时产生的侧压力。本发明方法简单、灵活，只需要在施工缝处钢筋网格内放入气囊并充满气即可，阻止了浇筑过程中混凝土溢出，妥善解决了平板混凝土结构施工时施工缝模板支拆困难问题，提升施工缝模板施工效率，优化施工进度，降低施工成本。
