Connecting structure of concrete precast beam and steel beam and construction method of connecting structure
The invention discloses a connecting structure of a concrete precast beam and a steel beam and a construction method of the connecting structure. The connecting structure comprises the concrete precast beam and the steel beam. Two grooves which are matched with the ends of the steel beam and are coaxial are reserved in the concrete precast beam, the two grooves are symmetrically formed in the two sides of the concrete precast beam, and a bolt hole for a split bolt to penetrate through is reserved between the two grooves. The ends of the two steel beams are arranged in the two grooves of the concrete precast beam, the split bolts penetrate through the bolt holes to fix the two steel beams, a fixing steel bar located on the upper sides of the steel beams is further arranged between the two steel beams, and the two ends of the fixing steel bar are welded and fixed to the two steel beams respectively. A gap at the joint of the concrete precast beam and the steel beam is filled with concrete. According to the connecting structure, the structural design is reasonable, the requirement for assembly precision is low, the steel beams are doubly fixed through the split bolts and the fixing steel bars, the gaps are filled with pouring concrete, and the connecting structure is good in reliability; the construction method is easy to operate and high in construction efficiency.
本发明公开了一种混凝土预制梁与钢梁的连接结构及其施工方法，连接结构包括混凝土预制梁和钢梁；混凝土预制梁上预留有与钢梁端部匹配且共轴的两凹槽，两凹槽对称布置在混凝土预制梁的两侧，两凹槽之间预留有供对拉螺栓穿过的螺栓孔洞；两钢梁的端部布置在混凝土预制梁的两凹槽中，对拉螺栓穿过螺栓孔洞后将两钢梁固定，两钢梁之间还设有位于钢梁上侧的固定钢筋，固定钢筋的两端分别与两钢梁焊接固定；混凝土预制梁与钢梁连接处的间隙内填充有混凝土。本发明的连接结构，结构设计合理，对装配精度要求低，利用对拉螺栓和固定钢筋对钢梁进行双重固定且在间隙处填充浇筑混凝土，连接结构可靠性好；施工方法操作简便且施工效率高。
