[0002] Box beam is a type of beam in bridge engineering. It is hollow inside and has flanges on both sides of the upper part, similar to a box. The box beam of reinforced concrete structure is divided into prefabricated box beam and cast-in-place box beam. The prefabricated beam yard is responsible for the prefabrication construction of the bridge box beam required in the bidding section. The prefabricated box beam is assembled with a steel inner mold and then hoisted as a whole and placed in the side mold. After the concrete is poured, the inner mold is removed. The internal space of the box beam is small, and the inner mold is gradually removed. The installation and removal of the inner mold in the existing technology is difficult, the joint seam misalignment is difficult to adjust, the labor cost is high, and the construction efficiency is low.

[0011] Furthermore, a supporting leg is installed at the bottom of the fixing seat.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The guide block and the slide system of the mobile bracket make the bracket move smoothly in the slide, which is convenient for adjusting the support position. The design of the fixed bracket and the mobile bracket enables the inner mold to be firmly supported on the support surface, thereby reducing the shaking and tilting of the inner mold during the disassembly and assembly process.

[0013] 2. The hydraulic cylinder equipped on the lifting seat can quickly adjust the height of the boss, making the lifting operation of the inner mold more efficient and reducing the time of manual operation; the assembly of the transport roller can effectively reduce the moving burden of the inner mold and reduce the intensity of manual handling of the inner mold, thereby improving the safety of the operation.
