Under-column foundation platform supporting formwork and construction method thereof
The invention discloses an under-column foundation platform supporting formwork. The formwork comprises a plurality of PC board units, wherein the PC board units are vertically and fixedly connected to one another in an end to end mode to form a rectangular frame supporting formwork structure, the PC board units are of composite layer board structures, one end parts of the PC board units are provided with countersunk screws in an internally sunk pre-embedded mode, the other ends of the PC board units are provided with fixing holes parallel to sections of the end parts, and the PC board units penetrate through the fixing holes through fixing bolts to be embedded into the countersunk screws of the another PC board units to realize end-to-end vertical connection of the different PC board units. The construction method comprises the following steps of PC board unit prefabrication, PC board unit transportation and hoisting, platform foundation measurement and positioning, earth excavation,cushion layer pouring, formwork snapline positioning, supporting formwork hoisting and fixing, recheck and fine adjustment and foundation backfilling. The under-column foundation platform supporting formwork has the characteristics of being simple in structure, high in applicability, strong in pressure bearing capacity and convenient to construct.
本发明公开了一种用于柱下基础承台的支撑模板，包括若干PC板单元，PC板单元彼此首尾互相垂直固定连接形成矩形框架支撑模板结构，PC板单元为复合层板结构，PC板单元其中一个端部内凹预埋设有沉头螺丝，另一个端部设有与端部截面平行的固定孔，PC板单元通过固定螺栓贯穿固定孔嵌入另一PC板单元的沉头螺丝实现不同PC板单元的首尾垂直连接；其施工方法包括以下步骤：PC板单元预制→PC板单元运输吊运→承台基础测量定位→土方开挖→垫层浇筑→模板弹线定位→支撑模板吊装固定→复验微调→地基回填。本发明的用于柱下基础承台的支撑模板具有结构简单、适用性强、承压能力强和施工方便的特点。
