Steel connection assembly type frame structure and support-free construction method
The invention provides a steel connection assembly type frame structure and a support-free construction method, and aims to simplify the construction process of an assembly type concrete structure, realize support-free installation and improve the construction efficiency. The structure comprises a prefabricated column, a prefabricated beam and a prefabricated floor slab, embedded profile steel is arranged in the prefabricated column and extends out of the side face of the prefabricated column, an I-shaped steel connecting piece is arranged at the end of the prefabricated beam, and full-length cantilever supports are arranged on the two sides of the prefabricated beam. I-shaped steel connecting pieces at the ends of the prefabricated column and the prefabricated beam are step-shaped and matched, support plates are respectively arranged at the upper contact part and the lower contact part, the prefabricated beam and the prefabricated column realize rigid connection of profile steel through welding, and meanwhile, stirrups and constructional steel bars are arranged outside profile steel connecting sections and are completely connected through post-pouring concrete. The construction method comprises the steps that the beams, the columns and the floor slabs are prefabricated in a factory, the prefabricated columns and the prefabricated beams are hoisted on site, the connecting pieces are welded, and the connecting parts are poured by installing the integrated formworks and the opposite-pull screws. The prefabricated floor slabs are spliced and connected through the additional construction short steel bars, and finally concrete pouring is conducted on slab joints and local areas of the beam ends, so that an overall structure is formed. The installation efficiency of the connection joint is improved, a scaffold does not need to be supported in the installation process, the workload of wet operation and on-site steel bar binding is reduced, and the construction quality and safety are improved.
本发明提供了一种钢连接装配式框架结构及免支撑施工方法，旨在简化装配式混凝土结构的施工工序，可实现免支撑安装提高施工效率。该结构包括预制柱、预制梁和预制楼板，其中预制柱内设有预埋型钢并向外伸出预制柱侧面，预制梁端部设有工字形钢连接件，预制梁两侧设有通长悬挑支座。预制柱和预制梁端的工字形钢连接件均呈阶梯状并匹配吻合，上下接触处分别设有支座板，预制梁与预制柱通过焊接实现型钢刚性连接，同时在型钢连接段外设有箍筋和构造钢筋并通过后浇混凝土完成全部连接。施工方法包括工厂预制梁、柱和楼板，现场吊装预制柱和预制梁，焊接连接件，并通过安装一体化模板和对拉螺杆进行连接部位的浇筑。预制楼板通过附加构造短钢筋拼接连接，最后进行板缝和梁端局部区域的混凝土浇筑，形成整体结构。本发明提高了连接节点的安装效率，安装过程不需要支撑脚手架，减少了湿作业和现场绑扎钢筋的工作量，提升了施工质量和安全性。
