Formwork supporting method for hollow sandwich plate
The invention provides a formwork supporting method for an open-web sandwich plate, which comprises the following steps of: deepening a formwork support plane to determine the positions of a steel pipe fastener transition area and a lantern frame; positioning and paying off to obtain the position of a vertical rod; erecting a formwork support; concrete is poured, and when the concrete strength of the beam slab reaches the first preset strength, the lantern frame outer formwork and the support are dismantled; and when the beam slab concrete strength reaches the second preset strength, the lantern frame is dismantled. According to the formwork supporting method for the open-web sandwich plate, the steel pipe fastener transition area is arranged, and the early-dismantling system is contained in the formwork supporting system, so that the problem that the modulus of a plate fastener frame is not matched with that of a grid structure of the open-web sandwich plate is effectively solved, and the reliability and construction efficiency of the formwork supporting system are greatly improved; when the concrete strength of the beam slab reaches 75%, most formwork supports can be removed, material turnover is accelerated, the construction cost is reduced, and the method has the advantages of being high in efficiency and safety and low in construction cost.
本发明提供了一种空腹夹层板的模板支撑方法，方法包括：深化支模架平面，以确定钢管扣件过渡区与灯笼架位置；定位放线，以获得立杆位置；搭设支模架；浇筑混凝土，并在梁板混凝土强度达到第一预设强度时拆除灯笼架外模板及支架；在梁板混凝土强度达到第二预设强度时拆除灯笼架。上述一种空腹夹层板的模板支撑方法，通过设置钢管扣件过渡区并将早拆体系纳入模板支撑体系，有效解决了盘扣架与空腹夹层板网格结构间模数不匹配的问题，极大提高了模板支撑体系的可靠性与施工效率；在梁板混凝土强度达到75％时，即可拆除大部分模板支架，加快材料周转，降低施工成本，具有效率高、安全性高、施工成本低的优点。
