[0024] This utility model has the following beneficial effects: 1. In this utility model, the middle mechanism and the end mechanism are internally connected. When operators perform steel-concrete composite beam docking operations, concrete can enter from the feed inlet of the middle mechanism or the end mechanism and reach their interiors. Alternatively, even without pouring, different installation methods of the steel structure can achieve a stable effect. The connecting mechanism is mainly used to connect the middle mechanism and the end mechanism, ensuring that the end mechanism and the middle mechanism will not shift during steel-concrete composite beam docking operations. The middle mechanism, the end mechanism, and the connecting mechanism are located on the same horizontal plane, ensuring that the poured concrete will not tilt or deform during use. This structure is not limited to rectangular tube beams, polygonal beams, cap-shaped beams, or circular beams, saving operating costs and improving the applicability of the device. This structure achieves cost savings and improves docking efficiency, solving the problem in existing technologies where the docking of traditional steel structures and concrete beams requires constant replacement of traditional steel structures of corresponding shapes, resulting in resource waste and high costs. Therefore, a steel-concrete composite beam docking structure is proposed.

The two sets of bolting holes 7 on both sides are used for bolting. Among the four sets of fixing holes 1 on the inner walls of the two sets of connecting plates 7, one set corresponds to the bolting hole 6 on the same side, and the other set corresponds to the bolting hole 7 on the same side. Fixing can be achieved by bolting and welding. Half of the connecting plate 7 is located inside the intermediate beam 7, and the other half is located in the two sliding grooves 4, which together assist in completing the docking operation. This structure realizes the effect of fixing the connecting plate 7 and the side beam 7 through two fixing methods, namely the bolting hole 8 and the welding hole 5 included in the fixing hole 1, which solves the problem that the welding method in the prior art is not only time-consuming and labor-intensive, but may also cause inconvenience in welding operations.
