[0002] The main arch of the bridge is curved and is made up of multiple main load-bearing beams. When building the bridge, it is necessary to adjust the angle of the main load-bearing beams, which are supported by corbel structures.

[0003] In existing technology, the main load-bearing beam and the corbel are integrally formed in the factory, and the angle between the main load-bearing beam and the corbel is fixed. Then, they are transported to a designated location for splicing. This method requires extremely high precision and consumes a lot of time in the prefabrication process. At the same time, due to the influence of the site environment, it is impossible to install according to the designed angle during the splicing process. Workers need to adjust the angle by cutting or welding later, which makes it difficult to maintain the quality of the main arch ring after connection. Utility Model Content

[0004] In view of the technical problems existing in the background art, the purpose of this utility model is to provide a bridge arch corbel structure that can adjust the angle of the main load-bearing beam while meeting the connection strength requirements between the main load-bearing beam and the corbel structure.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A bridge arch corbel structure includes a main load-bearing beam, an adjusting diagonal brace, and several shear members. The main load-bearing beam includes a beam body and a support member connected to one side of the beam body. The support member and one end of the adjusting diagonal brace are rotatably connected. The adjusting diagonal brace includes a connector, a connecting rod, and an adjusting rod disposed between the connector and the connecting rod. The connector and the adjusting rod are rotatably connected, and the connector can be adjusted to a position on the adjusting rod. One end of the beam body is rotatably connected to the shear members, and one end of the connecting rod is rotatably connected to the shear members.

[0007] Preferably, the shear member includes a frame, the upper part of which is provided with a groove, and one end of the beam is rotatably connected in the groove.

[0008] Preferably, a hole is provided in the middle of the frame, and a rod for supporting the frame is provided in the hole.

[0009] Preferably, the lower part of the frame is provided with a connection hole, and a support rod is provided in the connection hole.

[0010] Preferably, one end of the connecting rod is provided with a threaded hole I, and the circumferential surface of the adjusting rod is provided with a threaded section that mates with the threaded hole I, and one end of the adjusting rod extends into the threaded hole I.

[0011] Preferably, the connector is hollow inside, and one end of the connector is provided with a threaded hole II, and one end of the adjusting rod extends into the connector through the threaded hole II.

[0012] This utility model has the following advantages and beneficial effects:

[0013] In this invention, the lower end of the main load-bearing beam is connected to an adjusting diagonal rod. An adjusting rod is installed inside the adjusting diagonal rod. By adjusting the position of the connector and the adjusting rod, the main load-bearing beam can be rotated, achieving the effect of changing the angle of the main load-bearing beam. During the subsequent connection process, workers can adjust the position of the main load-bearing beam to make the connection between multiple main load-bearing beams more stable, ensuring the connection quality while accelerating the construction progress.
