Jig frame system construction method of multi-layer cantilever structure
The invention provides a jig frame system construction method of a multi-layer cantilever structure. The jig frame system construction method comprises the steps of working condition analysis before construction, jig frame system selection, jig frame system installation, cantilever structure construction and jig frame system dismantling. The jig frame system is of a steel jig frame supporting structure and comprises a lower base, jig frame standard knots, a conversion steel beam, a conversion platform, a hydraulic adjusting device, an I-shaped steel cushion beam and an adjusting steel plate gasket from bottom to top. According to the construction method, in the construction process, the hydraulic adjusting device can be used for flexibly adjusting the height of the jig frame system according to different elevations, the lower-layer jig frame serves as an upper-layer back-jacking part during construction of the multi-layer cantilever structure, the measure investment can be reduced, the safety and quality hidden danger problems caused by excessive deformation during unloading are avoided, and the construction efficiency is improved. Components are modularized and can be recycled, and certain economic benefits are achieved. The problems that when a traditional multi-layer cantilever structure is constructed, the erecting height of a supporting jig frame is difficult to adjust, the structural safety is influenced by overlarge stress during unloading, and potential quality hazards are likely to occur after unloading are solved.
本发明提供了一种多层悬挑结构的胎架体系施工方法，包括施工前分析工况、胎架体系选择、安装胎架体系、进行悬挑结构施工、拆除胎架体系；胎架体系采用钢胎架支撑结构，自下而上包括下部底座、胎架标准节、转换钢梁、转换平台、液压调节装置、工字钢垫梁、调节钢板垫片。本发明所述施工方法在施工过程中可以利用液压调节装置根据不同标高灵活调整胎架体系高度，多层悬挑结构施工时下层胎架充当上层回顶，能够减少措施投入，卸载时避免过大形变造成的安全、质量隐患问题，构件模块化可再次周转利用，具有一定的经济效益。本发明解决了传统多层悬挑结构施工时支撑胎架搭设高度难以调节、卸载时应力过大影响结构安全、卸载后易生质量隐患等问题。
