Cast-in-place box girder flange plate cantilever supporting frame construction method
The invention relates to a construction method of an overhanging supporting frame, and aims to solve the technical problem that the construction cost is high when non-detachable obstacles such as near railways and cables exist in an existing construction method. The invention provides a cast-in-place box girder flange plate cantilever supporting frame construction method. Comprising the following steps of frame body foundation treatment, lower part disc buckle frame building, steel pipe inclined strut building, I-shaped steel mounting, flange plate disc buckle support building, flange plate and box girder bottom plate formwork building, first-time concrete pouring, cantilever I-shaped steel prestressed steel strand mounting and tensioning, adjusting of jacking at the upper end of a vertical rod of a lower part disc buckle support. Inclined strut jacking supports are arranged on the tops of the steel pipe inclined struts, flange plate disc buckle supports are adjusted, concrete is poured, and a frame body is dismantled; according to the construction method, the construction problem caused when the construction method is close to non-detachable obstacles such as railways and cables is solved, the construction quality of the cast-in-place box girder can be ensured through the use of the prestressed steel strands, and the construction safety is ensured.
本发明涉及涉及悬挑支撑架施工方法，以解决现有施工方法在针对存在临近铁路、线缆等不可拆卸障碍物时施工成本较高的技术问题。本发明提供的一种现浇箱梁翼缘板悬挑支撑架施工方法，包括如下步骤：架体基础处理、搭建下部盘扣架、搭建钢管斜撑、安装工字钢、搭建翼缘板盘扣支架、搭建翼缘板和箱梁底板模板、第一次混凝土浇筑、悬挑工字钢预应力钢绞线安装及张拉、调整下部盘扣支架的立杆上端的顶托、钢管斜撑顶部的斜撑顶托、调整翼缘板盘扣支架、混凝土浇筑和拆除架体；本发明克服了在临近铁路、电缆等不可拆卸的障碍物时的施工难题，而且通过预应力钢绞线的使用，可以确保现浇箱梁的施工质量，确保施工安全。
