The positions of the installation holes 221 correspond to the positions of the reinforcing rib plates 222 among them, so as to ensure that when the transverse rod 26 is inserted into the interior of the installation holes 221, the pressure it receives will directly act on the reinforcing rib plates 222, preventing the low load-bearing capacity of the installation holes 221 caused by the external force on a single load-bearing main body 22. A load-bearing self-locking oil cylinder is fixedly provided at the top of one end of the load-bearing main body 22, and a contact plate is provided at the top of the load-bearing self-locking oil cylinder, so as to ensure that the angle of the load-bearing main body 22 on the bridge main body 1 can be adjusted to ensure the level of the load-bearing main body 22. The load-bearing main body structure is a standard rectangular main beam or a trapezoidal main beam or a single-inclined-head rectangular main beam or a double-inclined-head main beam or a parallel-head main beam.

[0025] See Figures 1 to 5, the present utility model also provides an outer mold adjusting device 2, including: two groups of oppositely arranged outer mold bodies 21 installed on a load-bearing main body 22, the outer mold bodies 21 cooperate with an inner mold 3 to form a casting area for casting a bridge main body 1, facilitating the casting and molding of the bridge main body 1; a transverse rod 26, which is inserted into the interior of the mounting hole 221, and a support rod is fixedly arranged between adjacent two of the transverse rods 26 to ensure the fixation of the positions between the transverse rods 26. A transverse adjusting member 24 for driving the transverse rod 26 to slide inside the mounting hole 221 is fixedly arranged on the support rod. By driving the transverse rod 26 to slide inside the mounting hole 221 through the transverse adjusting member 24, the position of the outer mold is further adjusted. A height adjusting member 29 for supporting the outer mold body 21 is arranged on the transverse rod 26. The position of the top of the outer mold is adjusted through the height adjusting member 29. At the same time, by arranging a plurality of height adjusting members 29 to cooperate with each other, it is convenient to adjust the level of the top of the outer mold body 21; a plurality of positioning adjusting lead screws 28, one end of the positioning adjusting lead screw 28 is rotatably connected to the load-bearing main body 22, and the other end is rotatably connected to the outer mold body 21. The position of the side mold can be positioned and fixed through the positioning adjusting lead screw.

[0026] Preferably, a support frame 27 is arranged on the inner side of the outer mold body 21 of the present utility model. There are two of the transverse rods 26 and four of the height adjusting members 29. The four height adjusting members 29 are respectively arranged at the ends of the two transverse rods 26. One end of the height adjusting member 29 is fixedly connected to the transverse rod 26, and the other end is fixedly connected to the support frame 27. Through the four height adjusting members 29, the heights of the four diagonals of the top of the outer mold body 21 can be adjusted, so as to realize the adjustment of the horizontal position of the top of the outer mold body 21.

[0027] Preferably, a triangular support 25 is correspondingly installed at the bottom of the mounting hole 221 on the transverse rod 26. A slide rail is arranged on the triangular support 25, and a pulley 23 cooperating with the slide rail is fixedly arranged on the transverse rod 26 to ensure that the transverse rod 26 can smoothly move on the triangular support 25, and further ensure that the transverse rod 26 smoothly moves inside the mounting hole 221. A transverse support is fixedly arranged at the bottom of the support frame 27, and the height adjusting member 29 is fixedly arranged at the bottom of the transverse support. An inner mold 3 is arranged between the two groups of outer mold bodies 21. During use, concrete is poured between the inner mold 3 and the outer mold, and at the same time, the positions of the outer mold body 21 and the inner mold 3 are moved after the concrete pouring is completed, so as to facilitate the demolding process of the concrete.

[0028] In this embodiment, when in use, the position of the outer mold is adjusted by adjusting the lateral adjustment member 24 and the height adjustment member 29, so that the outer mold and the inner mold 3 cooperate to form an interval for pouring concrete. At the same time, after the pouring is completed, when demolding is required, the outer mold is driven to move by the height adjustment member 29 and the lateral adjustment member 24, thereby separating the outer mold from the concrete and completing the demolding process.

At least two mounting holes are provided on the load-bearing main body, and the positions of the mounting holes correspond to the positions of the reinforcing ribs therein, so as to ensure that when the transverse rod is inserted into the interior of the mounting hole, the load-bearing main body can be moved as needed. The pressure will directly act on the reinforced rib plate to prevent the single load-bearing body from being subjected to external force, resulting in a low load-bearing capacity of the installation hole. A load-bearing self-locking cylinder is fixedly provided on the top of one end of the load-bearing body, and an abutment plate is provided on the top of the load-bearing self-locking cylinder, thereby ensuring that the angle of the load-bearing body on the bridge body can be adjusted to ensure the level of the load-bearing body.

A support rod is fixedly arranged between adjacent two of the transverse rods to ensure the fixation of the positions between the transverse rods. A transverse adjusting member for driving the transverse rod to slide inside the installation hole is fixedly arranged on the support rod. The transverse rod is driven to slide inside the installation hole by the transverse adjusting member to further adjust the position of the outer mold. A height adjusting member for supporting the outer mold body is arranged on the transverse rod. The position of the top of the outer mold is adjusted by the height adjusting member. At the same time, by arranging a plurality of height adjusting members to cooperate with each other, it is convenient to adjust the level of the top of the outer mold body; several positioning adjusting lead screws, one end of each positioning adjusting lead screw is rotatably connected to the load-bearing main body, and the other end is rotatably connected to the outer mold body.
