Beam bottom formwork support of variable cross-section concrete cast-in-place box beam and construction method
The invention provides a variable cross-section concrete cast-in-place box girder bottom formwork support and a construction method.The variable cross-section concrete cast-in-place box girder bottom formwork support comprises a full framing and an auxiliary support, the top of the full framing is not higher than the top of a pier column, and the auxiliary support is fixed to the top of the full framing; the line type of the top of the auxiliary support is matched with the bottom curve of the box girder, and the top of the auxiliary support is used for installing a formwork to conduct cast-in-place of the box girder. The device is simple and reliable in structure and convenient to operate, the time for repeatedly adjusting the full framing before formwork construction is saved, the auxiliary support and the bottom formwork can be synchronously constructed with the full framing, and the working efficiency of variable cross-section concrete cast-in-place box girder construction can be improved.
本发明提供一种变截面混凝土现浇箱梁梁底模板支架及施工方法，变截面混凝土现浇箱梁梁底模板支架包括满堂支架和辅助支架，所述满堂支架的顶部不高于墩柱的顶部，所述辅助支架固定在满堂支架的顶部，所述辅助支架顶部的线型与箱梁的底部曲线相适应，所述辅助支架的顶部用于安装模板进行箱梁的现浇。本发明结构简单、可靠、操作方便，节约了模板施工前对满堂支架反复调整的时间，且辅助支架和底模可与满堂支架同步施工，有利于提高变截面混凝土现浇箱梁施工的工作效率。
