[0027] Please refer to Figures 1-4 , the present utility model provides a technical solution: a steel - concrete composite structure beam, including a concrete main body 1, a frame 3 is filled inside the concrete main body 1, an I - shaped steel 2 is filled inside the concrete main body 1 located inside the frame 3, both ends of the I - shaped steel 2 are respectively fixedly connected with multiple groups of connecting pieces 4, one side of each group of connecting pieces 4 far from the I - shaped steel 2 is respectively fixedly connected with an auxiliary bar 5, the auxiliary bar 5 abuts against the frame 3, a locking mechanism is arranged between both sides of the I - shaped steel 2 and the frame 3, the frame 3 includes four longitudinal bars 301, the four longitudinal bars 301 are respectively located at the four corners of the I - shaped steel 2, and multiple groups of large stirrups 302 are respectively clamped on the outer walls of every two longitudinal bars 301.

[0028] In the technical solution of the present utility model, the I - shaped steel 2 can play a role in fixing multiple connecting pieces 4, and the connecting pieces 4 can play a role in fixing the auxiliary bars 5. Then, the I - shaped steel 2 can play a role in abutting against the frame 3 under the cooperation of the connecting pieces 4 and the auxiliary bars 5, so that the stability of the frame 3 can be improved both before and after the concrete is poured.

[0029] In addition, the large stirrups 302 can play a role in stably clamping the four longitudinal bars 301.

[0030] In the technical solution of the present utility model, such as Figure 1 , Figure 2 and Figure 4As shown in the figure, the locking mechanism includes two groups of overlapping plates 6. The two groups of overlapping plates 6 are fixedly connected to the I-beam 2, and the two groups of overlapping plates are respectively located in the recesses on both sides of the I-beam 2. Welding rods 7 are respectively welded to the upper ends of the two groups of overlapping plates 6. The I-beam 2 can fix the overlapping plates 6, and the overlapping plates 6 can fix the welding rods 7. A plurality of cross bars 8 are welded to the outer walls of the plurality of welding rods 7 away from the overlapping plates 6. A plurality of support rods 9 are welded to one side of the plurality of cross bars 8 away from the welding rods 7. The welding rods 7 can fix the cross bars 8, and the cross bars 8 can fix the support rods 9. Small stirrups 10 are clamped between the outer wall of the welding rod 7 and the outer wall of the frame 3. The small stirrups 10 can lock the welding rod 7, the connecting piece 4, the support rod 9 and the frame 3.

[0031] In the technical solution of the present utility model, as Figure 3 shown, the position of each group of small stirrups 10 corresponds to that of each group of large stirrups 302. By making the positions of each group of small stirrups 10 correspond to those of each group of large stirrups 302, the stability of the frame 3 can be enhanced.

[0032] In the technical solution of the present utility model, as Figure 1 shown, the frame 3, the overlapping plates 6, the connecting piece 4, the auxiliary ribs 5, the welding parts, the cross bars 8 and the support rods 9 are all made of steel. By making the frame 3, the overlapping plates 6, the connecting piece 4, the auxiliary ribs 5, the welding parts, the cross bars 8 and the support rods 9 all made of steel, the high strength and durability of these components are ensured, and the performance of the entire structural beam is further enhanced.

[0033] When in use, first, this structural beam mainly consists of a concrete main body 1 and a steel section frame 3 inside. The concrete main body 1 provides the overall structural strength and stability, while the steel section frame 3 increases the load-bearing capacity and shear resistance of the beam. In the frame 3 inside the concrete main body 1, I-shaped steel 2 is filled. As an efficient load-bearing material, I-shaped steel 2 can significantly enhance the load-bearing capacity of the beam. Especially when bearing bending and shear forces, both ends of the I-shaped steel 2 are fixedly connected to the auxiliary reinforcement 5 through multiple groups of connecting pieces 4. The auxiliary reinforcement 5 abuts against the frame 3, providing additional support and fixation for the I-shaped steel 2 to ensure that the I-shaped steel 2 will not move or deform when stressed. The locking mechanism consists of a lap plate 6, a welding rod 7, a cross bar 8 and a support rod 9. They work together to further fix the I-shaped steel 2 and the frame 3, enhancing the stability of the overall structure. The lap plate 6 is connected to the outer wall of the frame 3 through the welding rod 7. The cross bar 8 and the support rod 9 provide additional support for the welding rod 7, forming a stable locking system. This locking system restricts the displacement of the I-shaped steel 2 in the concrete main body 1, enhancing the integrity and stability of the structure. Small stirrups 10 and large stirrups 302 are respectively clamped on the welding rod 7 and the longitudinal bars 301 of the frame 3, providing additional shear resistance and restraint for the structure. They ensure the tight combination between the concrete main body 1 and the steel section frame 3, preventing relative displacement between the two. The positions of the small stirrups 10 and the large stirrups 302 correspond to each other, further enhancing the integrity and collaborative working ability of the structure. The main materials used in this structural beam include concrete and steel. Concrete has good compressive performance and durability, while steel has high strength and excellent tensile performance. The combination of these two materials enables the structural beam to maintain good performance and stability when bearing various complex loads. The lap plate 6, the connecting pieces 4, the auxiliary reinforcement 5, the welding parts, the cross bar 8 and the support rod 9 are all made of steel, ensuring the high strength and durability of these components and further enhancing the performance of the entire structural beam. In summary, through reasonable design and material selection, this steel-concrete composite structural beam achieves high strength, high stability and good durability. When bearing various loads, it can maintain stable performance, providing reliable support for buildings.
