Construction method of structural steel cast-in-place slab reinforced concrete superposed beam
The invention relates to a construction method of a structural steel cast-in-place slab reinforced concrete superposed beam. The construction method comprises the following steps: preparing for construction; field intersection traffic organization optimization is carried out; erecting a temporary support system; transporting and hoisting steel beams; construction of a self-supporting protection system hung below the intersection; welding and coating a steel beam on site, and dismantling a bracket upright post; and constructing the self-supporting formwork system. The steel beam transportation jig frame has the beneficial effects that the shaped stable steel beam transportation jig frame is adopted in the steel beam section transportation process, the steel beam entering efficiency is effectively improved, and the steel beam entering quality is guaranteed; the method is suitable for steel-concrete superposed beam operation, and is particularly suitable for composite beam engineering construction of an overpass crossing road section; according to the structural steel cast-in-place slab reinforced concrete superposed beam, the problems of construction efficiency and construction safety of the grade crossing are solved, the entering quality of the steel beam is effectively guaranteed, the support cost of the cast-in-place slab is reduced, and the technical benefit is remarkable.
本发明涉及一种型钢现浇板钢混叠合梁的施工方法，包括步骤：施工准备；现场平交口交通组织优化；临时支架体系搭设；钢梁运输吊装；平交口下挂自承式防护体系施工；钢梁现场焊接、涂装，支架立柱拆除；自承式支模体系施工。本发明的有益效果是：本发明在钢梁节段运输过程中采用定型化稳固钢梁运输胎架，有效提高钢梁进场效率，并保障钢梁进场质量；本发明适用于钢混叠合梁作业，尤其适用于上跨平交口路段的组合梁工程施工；本发明采用的型钢现浇板钢混叠合梁解决了平交口施工效率及施工安全问题，并有效保障钢梁进场质量，降低现浇板的支架成本，技术效益显著。
