[0007] Furthermore, the side support adjustment member includes a shell seat fixed to the lower end surface of one end of the bottom support seat, and a rotating shaft is penetrated and rotatably installed on one side of the lower end of the shell seat, both ends of the rotating shaft are fixedly connected with screws, the other end of the screw is threadedly connected with a threaded sleeve matching it, the other end of the threaded sleeve is slidably sleeved with a limiting cylinder, and the limiting cylinder is positioned and fixed to the threaded sleeve by a fastening bolt arranged on itself, the end of the limiting cylinder away from the rotating shaft is hinged with an adjusting rod, the lower end of the movable plate is fixed with a convex rod, and the other end of the adjusting rod is hinged to the lower end of the convex rod on the same side.

[0008] Furthermore, the thread directions of the screws at two ends of the rotating shaft are opposite.

[0009] Furthermore, a handle is rotatably mounted on the front side of the housing seat, one end of the handle is located inside the housing seat and is provided with a main bevel gear, and the middle section of the rotating shaft is located inside the housing seat and is provided with a slave bevel gear meshing with the main bevel gear.

[0010] Furthermore, a side surface of the limiting plate is provided with a plurality of bolt holes adapted to the fixing bolts.

[0011] The beneficial effect of the technical solution provided by the embodiment of the utility model is that when the bracket supports the beam formwork of the bridge, it can not only support the bottom of the formwork, but also support the formwork on both sides of the beam. The bracket integrates the bottom support and the side support into one, and there is no need to set up a separate side support device. It is convenient and quick to use, saves time, and reduces the time cost of construction.

[0012] When the bracket supports the template on the side of the beam, the distance between the two supporting balls can be adjusted, thereby facilitating the support of the side templates of beams of different widths, thereby improving the applicability of the bracket.
