Large-span steel bar truss floor support plate unsupported concrete pouring system and construction method
The invention relates to a support-free concrete pouring system for a large-span steel bar truss floor support plate and a construction method. The construction method comprises the operation modes of a post-dismantling bracket supporting frame system, a temporary inclined strut adding system, a finalization reserved pipeline box, a beam-column joint reinforcing system, a frame beam cable-stayed hanging system and a beam face stand column tie reinforcing system. The connecting structure has the beneficial effects that when the steel bar truss floor support plate is connected with the shear wall, a post-demolition bracket supporting frame system is adopted, and the shear wall bar pre-embedded sleeve is arranged to be connected with the floor support plate steel bar, so that the construction quality of the joint is improved; a temporary diagonal bracing system is adopted during construction of the cantilever floor support plate, and the mounting construction quality of the cantilever section is improved through supporting of the adjustable diagonal bracing; the beam-column joint reinforcing technology is adopted at the position of the steel frame column, the grout leakage prevention reinforcing plate is arranged, it is guaranteed that grout leakage and the like are not prone to occurring during concrete pouring, and then the construction quality of the whole floor is improved.
本发明涉及一种大跨度钢筋桁架楼承板无支撑混凝土浇筑体系及施工方法，包括后拆除牛腿撑架体系、临时加斜撑体系、定型化预留管线盒、梁柱节点补强体系、框架梁斜拉吊挂体系和梁面立柱拉结加固体系的操作方式。本发明的有益效果是：钢筋桁架楼承板与剪力墙连接时采用了后拆除牛腿撑架体系，并设置剪力墙筋预埋套筒和楼承板钢筋连接，提高了节点的施工质量；悬挑楼承板施工时采用了临时加斜撑体系，通过可调式斜撑进行支撑，提高了悬挑段的安装施工质量；在钢框架柱位置采用梁柱节点补强技术，并设置防漏浆加强板，保证了混凝土浇筑时不易发生漏浆等现象，进而提高了整个楼板的施工质量。
