Cast-in-place concrete main arch ring triangular steel arch formwork system and construction method
The invention relates to a cast-in-place concrete main arch ring triangular steel arch frame formwork system which comprises an arch foot anchoring system, an arch foot fixing type steel frame, a hanging basket suspended pouring system, a main arch ring adjustable arch frame and a cast-in-place support system. Comprising the steps of pier body construction, double-column foundation and short-column foundation construction, cast-in-place support system erection, arch foot anchoring system construction, arch foot fixing type steel frame construction, arch ring adjustable arch frame construction, hanging basket installation, water tank pre-pressing system construction and main arch ring concrete pouring. The method has the beneficial effects that one end of the steel arch frame is supported through the arch foot anchoring system; the other end of the steel arch frame is supported by the arch foot fixing type steel frame; the hanging basket suspended pouring system can be used for sliding supporting of the steel arch frame, and the concrete arch ring pouring construction efficiency of formwork supporting is greatly improved; the steel arch frame with the adjustable main arch ring can be suitable for construction of an arch axis within a certain range; the lower portion of the cast-in-place full framing is supported through bailey beams and short stand columns.
本发明涉及一种现浇混凝土主拱圈三角钢拱架支模体系，包括：拱脚锚固体系、拱脚固定型钢架、挂篮悬浇体系、主拱圈可调式拱架和现浇支架体系；包括步骤：墩身施工、双柱基础及短柱基础施工、现浇支架体系搭设、拱脚锚固体系施工、拱脚固定型钢架施工、拱圈可调式拱架施工、挂篮安装、水箱预压体系施工、主拱圈混凝土浇筑。本发明的有益效果是：通过拱脚锚固体系支撑钢拱架的一端；通过拱脚固定型钢架支撑钢拱架的另一端；挂篮悬浇体系可以进行钢拱架的滑移支设，大幅提高了支模的混凝土拱圈浇筑施工效率；主拱圈可调式钢拱架可适用于一定范围内拱轴线的施工；现浇满堂支架下方通过贝雷梁和短立柱进行支撑。
