[0028] In the related art, a method of setting up a full-height support from the ground is adopted as a bracket for the flange plate casting construction. However, this structure is complicated to set up and occupies ground space, and cannot ensure the passage of the road under the bridge. Therefore, a bracket that is easy to operate is needed to ensure the casting construction of the flange plate of the steel-concrete composite beam.

[0029] To solve the above technical problems, Figure 1 to Figure 2 As shown, the embodiment of the present application provides a steel-concrete composite beam flange plate support bracket, comprising: a horizontal connector 11, a vertical connector 13 and an oblique connector 12, wherein the horizontal connector 11, the vertical connector 13 and the oblique connector 12 are fixedly connected in sequence to form a triangular support structure 1;

[0030] A first screw rod 5 is vertically fixed to the upper end of the triangular support structure 1, and the first screw rod 5 is used to pass through the reserved hole of the steel beam top plate 3 and be fixed;

[0031] A sleeve 8 is fixed to the lower end of the triangular support structure 1 in the horizontal direction, and a second screw rod 7 is passed through the sleeve 8. The end of the second screw rod 7 is used to abut against the steel box girder web 2. A first nut 9 is fastened on the second screw rod 7. The first nut 9 is located between the sleeve 8 and the steel box girder web 2, and the first nut 9 abuts against the end of the sleeve 8.

[0032] In this embodiment, the horizontal connector 11, the vertical connector 13 and the oblique connector 12 are connected end to end to form a triangular support structure 1, wherein the horizontal connector 11 serves as a support structure in direct contact with the flange plate casting template. In order to enable the entire triangular support structure 1 to be fixed on the steel beam in a cantilevered manner, in this embodiment, a first screw 5 is fixed on the upper end of the triangular support structure 1, and a corresponding reserved hole matching the first screw 5 is reserved on the top plate 3 of the steel beam. The first screw 5 can be fixed after passing through the reserved hole vertically, and can be fixed by screwing on a nut, so that the triangular support structure 1 can be fixed on the top plate 3 of the steel beam. In order to make the triangular support structure 1 more stable when subjected to stress, it is necessary to support it laterally. For this purpose, a sleeve 8 is fixed at the lower end of the triangular support structure 1 in this embodiment. A second screw 7 is inserted into the sleeve 8. The second screw 7 is arranged in the horizontal direction, and one end of the second screw 7 can be against the steel box beam web 2. Therefore, when the triangular support structure 1 is subjected to downward pressure, the second screw 7 can be used to transfer the pressure to the steel box beam web 2, and the steel box beam web 2 supports it, thereby improving stability. At the same time, under the tightening action of the first nut 9, the first screw 5 cannot move in the direction away from the steel box beam web 2, and the transverse slope of the horizontal connector 11 can be fine-tuned by turning the first nut 9.

[0033] This embodiment achieves the purpose of fixing the triangular support structure 1 on the side of the steel beam in a cantilevered manner and using the triangular support structure 1 to support the flange plate casting formwork, thereby achieving the technical effect of not occupying the ground space under the bridge, ensuring the normal traffic of the road under the bridge, and being relatively convenient for erection and disassembly, thereby solving the problem in the related technology that the support structure of the flange plate of the steel-concrete composite beam during casting construction is complex, requires occupying ground space, and cannot ensure the normal traffic of the road under the bridge.

[0034] To facilitate the installation of the first screw rod 5, the support bracket in this embodiment further includes a first connecting member 24, a connecting piece 6 and an isolation column 22;

[0035] The first connecting member 24 is disposed at the upper end of the vertical connecting member 13 and is opposite to the horizontal connecting member 11. Two isolation columns 22 are provided, one of which is located between the first connecting member 24 and the vertical connecting member 13 and is fixed by welding, and the other is located between the first connecting member 24 and the horizontal connecting member 11 and is fixed by welding, so that a screw installation gap 23 is formed between the first connecting member 24 and the horizontal connecting member 11;

[0036] There are two connecting pieces 6 and they are fixed to the upper and lower ends of the first connecting member 24 respectively;

[0037] The connecting plate 6 is provided with a connecting hole 25 , which corresponds to the screw installation gap 23 . The lower end of the first screw 5 passes through the connecting hole 25 and the screw installation gap 23 and is then fixed.

[0038] In this embodiment, the isolation column 22 can be made of truncated steel bars, which is convenient for on-site production. The diameter of the isolation column 22 is slightly larger than the diameter of the first screw 5, so that a screw installation gap 23 that allows the first screw 5 to pass through can be formed between the first connector 24 and the horizontal connector 11. To facilitate the positioning of the first screw 5, a connecting piece 6 is welded and fixed at the upper and lower ends of the horizontal connector 11, and the connecting piece 6 can be a steel sheet. The first screw 5 can pass through the connecting hole 25 on the connecting piece 6 and be locked by a nut.

[0039] In order to prevent the end of the second screw 7 from directly applying pressure to the steel box girder web 2, resulting in paint peeling on the surface of the steel box girder web 2 and excessive local pressure, in this embodiment, a second connecting member 21 is fixed to one end of the second screw 7 facing the steel box girder web 2, and a connecting groove is formed on the second connecting member 21 on one side facing the steel box girder web 2, and a square timber 20 is installed in the connecting groove, and the end face of the square timber 20 is used to abut against the steel box girder web 2.

[0040] In one embodiment, the lower end of the first screw rod 5 passes through the connecting piece 6 and is locked by the second nut 4, and the upper end of the first screw rod 5 passes through the steel beam top plate 3 and is locked by the second nut 4. Further, the vertical connector 13, the horizontal connector 11 and the diagonal connector 12 are all made of channel steel, and the vertical connector 13, the horizontal connector 11 and the diagonal connector 12 are welded and fixed. Further, the length of the horizontal connector 11 is 1.9m, the length of the vertical connector 13 is 1.2m, and the length of the diagonal connector 12 is 1.98m.

[0041] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Within the spirit and principle of the present application, any modification, equivalent replacement, improvement, etc. made shall be included in the protection scope of the present application.
