Steel-concrete composite beam connecting structure and design calculation method
The invention discloses a steel-concrete composite beam connecting structure and a design calculation method. The connecting structure comprises prefabricated concrete floors, an H-shaped steel beam, a rear steel bar frame, rear through longitudinal bars and post-pouring concrete. A longitudinal through groove and a plurality of vertical through grooves are formed in the side surface of the connecting side of the prefabricated concrete floor, connecting steel bars extend out of the vertical through grooves, and hooks are formed at the ends of the connecting steel bars; the prefabricated concrete floors on the two sides are spliced on the upper flanges of the H-shaped steel beams; the rear steel bar frame is arranged in the middle of the vertical through grooves formed by butt joint of the floors on the two sides; the rear through longitudinal bars penetrate through the rear steel bar frame and the hooks at the ends of the connecting steel bars; and the post-pouring concrete is poured in the longitudinal through groove and the multiple vertical through grooves. The technical problems that a hogging moment area of a traditional steel-concrete composite beam is prone to cracking, low in construction efficiency and poor in durability are solved, and the steel-concrete composite beam connecting structure has the advantages of being reliable in performance, simple in structure, convenient to splice in an industrialized production site, high in construction efficiency and the like.
本发明公开了一种钢‑混组合梁连接构造及设计计算方法，该连接构造包括预制混凝土楼板、H型钢梁、后置钢筋架、后置贯穿纵筋以及后浇混凝土，预制混凝土楼板在连接侧的侧面开有纵向贯通槽和多个竖向贯通槽，在竖向贯通槽内伸出有连接钢筋，连接钢筋端部形成有弯钩；两侧的预制混凝土楼板拼接在H型钢梁上翼缘上；后置钢筋架居中设置在两侧楼板对接形成的竖向贯通槽内；后置贯穿纵筋从后置钢筋架和连接钢筋端部的弯钩中穿过；后浇混凝土浇筑在纵向贯通槽和多个竖向贯通槽中。本发明解决了传统钢‑混组合梁负弯矩区易开裂、施工效率低和耐久性差的技术问题，具有性能可靠、构造简单、便于工厂化生产现场拼接方便，施工效率高等优势。
