[0002] Bailey beam support is a truss beam composed of standard components. It has the characteristics of simple structure, light weight, economy, wide application, strong adaptability, strong interchangeability and easy assembly. Bailey beam was invented during World War II to quickly build bridges to meet the needs during the war. It can be supported by connecting steel rods or cables, and can also be constructed with materials such as bricks, stones, and concrete. Bailey beams can not only be directly assembled into a complete bridge as a whole set, but also can be spliced ​​into a variety of structures using only its main components, such as steel temporary bridges, construction brackets, bridge erection machines, suspended cast baskets, gantry frames, etc. This structure is flexibly used in a variety of projects. Because of its rapid erection and strong mobility, it was mostly used to build simple bridges on rivers and cliffs during wartime, and is now mostly used in engineering construction.

The utility model has a simple structure and a reasonable design. The tightening bolts are used to make the support member tightly attached to the top of the Bailey beam, which effectively solves the problem of reinforcing the Bailey beam bracket at non-supporting points, reduces construction safety risks, reduces labor intensity, and helps to improve construction efficiency.

[0004] However, during the use of the utility model, since the length of the support rod is fixed and the spacings of different types of Bailey frames are different, support rods of various lengths are needed, which may cause a large number of support rods to be wasted, increase production costs, and fail to meet production needs. Therefore, a vertical reinforcement device for a Bailey beam bracket is proposed to solve the above-mentioned problems. Utility Model Content

[0010] Furthermore, there are two threaded sleeves, which are symmetrically distributed outside the bidirectional threaded rod, and a first hinged part is distributed on the top and bottom of each threaded sleeve.

[0011] Furthermore, a rotating sleeve that rotates the bidirectional threaded rod is rotatably connected to one side of the support box, an insertion rod extending to the outside of the rotating sleeve is slidably connected inside the rotating sleeve, and a rotating handle is fixedly connected to one end of the insertion rod away from the support box.

[0012] Furthermore, a return spring is fixedly connected to the interior of the insertion rod, and one end of the return spring is fixedly connected to an elastic block extending to the outside of the rotating sleeve.
