Construction method of prefabricated multi-ribbed cavity floor
The invention provides a construction method of a prefabricated multi-ribbed cavity floor, and belongs to the technical field of prefabricated multi-ribbed plate construction. The construction method of the prefabricated multi-ribbed cavity floor comprises the steps of full-hall scaffold building, main keel laying, overall leveling and the like. The construction method comprises the steps that S1, full-hall scaffold building is conducted, specifically, when a full-hall scaffold is built, vertical rods on the upper layer and the lower layer are required to be aligned, the vertical rods are uniformly arranged from the two sides of a cast-in-place ribbed beam, the vertical rods are arranged at the intersection positions of floor elastic bidirectional lines, and scaffold boards are laid under the vertical rods; S2, main keels are laid, specifically, when the main keels are installed, the main keels are required to be arranged in order and not to be inclined, and the two vertical rods at the intersection positions must abut against the main keels; and S3, overall leveling is conducted, specifically, after the main keels are laid, overall leveling is conducted according to control lines, and full-hall scaffold formworks are hoisted on the main keels. The cavity formworks are supported by placing the modularized cavity formworks which are machined and formed in a factory-like mode, and accurate and rapid installation of an upper plate of the prefabricated multi-ribbed plate is achieved by installing limiting square pipes.
本发明提供了一种预制密肋空腔楼板施工方法，属于预制密肋板施工技术领域，该一种预制密肋空腔楼板施工方法包括满堂脚手架搭建、铺设主龙骨和整体调平等步骤，S1，满堂脚手架搭建：搭设满堂脚手架时，要求上下两层的立杆对齐，立杆从现浇肋梁两侧统一开始排布，并在楼面弹双向线的交叉部位设置立杆，立杆下铺垫脚手板；S2，铺设主龙骨：安装主龙骨时，要求主龙骨排放要整齐，不得歪斜，并且交叉处的两个立杆与主龙骨必须靠紧；S3，整体调平：主龙骨铺设完成后，要根据控制线对整体进行调平，并向主龙骨上吊装满堂脚手架模板；通过放置工厂化加工成型的模块化空腔模板实现空腔模板的支撑，通过安装限位方管实现预制密肋板上板的准确快速安装。
