[0002] A box girder is a type of beam used in bridge engineering. It is hollow inside and has flanges on both sides of the upper part, similar to a box, hence the name. It is divided into single-box and multiple-box types. Box girders with reinforced concrete structures are divided into prefabricated box girders and cast-in-place box girders. Box girders prefabricated in an independent site can be erected in combination with a bridge-erecting machine after the lower project is completed, which can speed up the project progress and save construction time. Cast-in-place box girders are mostly used for large continuous bridges.

[0003] For example, the patent document with the announcement number CN 207017165 discloses a temporary support frame for supporting a steel box girder. The temporary support frame includes four pipe columns fixed on the foundation, and the four pipe columns are collectively arranged to form a space convenient for accommodating piers. Among the four pipe columns, a plurality of mutually detachably connected first cross beams are arranged between the upper ends of two adjacent pipe columns, and the plurality of first cross beams are collectively arranged to form a main frame, and a plurality of supporting beams for supporting the steel box girder are fixed at the upper end of the main frame. The utility model has the advantages of low cost, simple installation, time saving and good stability.

[0004] However, when the structure is actually supporting the steel box girder, it is unable to perform a more stable and adaptive docking and fixing operation with the bottom of the box girder, resulting in the equipment being unable to perform adaptive docking and supporting operations according to the sizes of different box girders. At the same time, the equipment is unable to perform a more secure locking and fixing operation with both sides of the box girder, and cannot meet daily use requirements. Therefore, it is urgent to design a supporting frame for supporting steel box girders to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a support frame for supporting steel box beams, so as to solve the problem that the existing structure proposed in the above background technology is unable to perform a more stable and adaptive docking and fixing operation with the bottom of the box beam when actually supporting the steel box beam, resulting in the equipment being unable to perform adaptive docking and supporting operations according to the sizes of different box beams. At the same time, the equipment is unable to perform a more secure locking and fixing operation with both sides of the box beam, and cannot meet daily usage requirements.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a support frame for supporting a steel box beam, comprising a support frame body, one side of the support frame body is fixedly connected to a first position-limiting side frame, the other side of the support frame body is fixedly connected to a second position-limiting side frame, a side surface of the first position-limiting side frame is provided with a rotating sleeve, and one end of the rotating sleeve is provided with a rotating disk;

[0007] A first support seat and a second support seat, wherein the first support seat is arranged on one side inside the support frame body, the second support seat is fixedly connected to the other side inside the support frame body, and a buffer side frame is movably connected inside the first support seat.

[0008] Preferably, a docking side plate is fixedly connected to the top of one end of the buffer side frame, and damping rubber strips are arranged on both sides of one end of the buffer side frame close to the first support seat.

[0009] Preferably, a contraction groove is provided inside the first support seat, and tension springs are evenly arranged inside the contraction groove.

[0010] Preferably, one end of the rotating disk is fixedly connected to a threaded rod, and two groups of threaded sleeves are arranged at the center of the surface of the threaded rod.

[0011] Preferably, a butt rubber pad is provided between the threaded sleeves, and a limiting slider is fixedly connected to the side of the threaded sleeve.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The support frame for supporting the steel box girder, through the set support frame body, first limiting side frame, second limiting side frame, rotating pipe sleeve, rotating disk, first support seat, second support seat, threaded rod, threaded sleeve, docking rubber pad, and limiting slider, can enable the equipment to perform a more adaptive bottom support operation with the supporting steel box girder. In actual use, the staff can adaptively dock the bottom of the support frame body to the bottom of the box girder, and then rotate the rotating disk at one end of the rotating pipe sleeve to drive the threaded rod to rotate, thereby driving the threaded sleeve connected to the first support seat to move, and then the first support seat is opened outward relative to the second support seat, so that the equipment is more adapted to the support position of the bottom of the box girder.

[0014] The supporting frame for supporting the steel box girder further improves the overall use effect of the equipment by means of the supporting frame body, the first supporting seat, the second supporting seat, the buffer side frame, the docking side plate, the damping rubber strip, the shrinkage groove and the tensioning spring. In daily use, when the first supporting seat is adjusted to limit the opening along the first limiting side frames on both sides of the supporting frame body, the buffer side frames and the docking side plates inside the first supporting seat and the second supporting seat can also be adaptively docked to the positions on both sides of the box girder. Then, the buffer side frame and the docking side plate are stabilized and limited and reinforced as a whole by the tensioning spring inside the shrinkage groove of the first supporting seat, so that the overall equipment can be more adapted to the adaptive docking and supporting operation between the supporting steel box girder, which reflects the practicality of the equipment design.
