Description

Technical Field

[0001] The utility model belongs to the technical field of bridge engineering, and more specifically, particularly relates to a supporting and reinforcing structure at the bottom of a bridge. Background Art

[0002] During the maintenance and construction of the bridge, in order to ensure the durability and support stability of the bridge, a reinforcement structure is often used to assist in supporting the bottom of the bridge. In the actual application of the existing reinforcement structure, the support plate is adjusted to the appropriate position, and the operator rotates multiple studs and nuts in sequence. After the support plate is installed on the outside of the bridge pillar, the lead screws at both ends are rotated respectively to make the support rods at both ends flip inward respectively until the support ball is pressed against the bottom of the bridge to achieve support reinforcement of the bottom of the bridge.

[0003] As shown in the existing application number CN202320341679.5, a quick-installation adjustable bridge reinforcement structure is disclosed, including a bridge, a fixing mechanism and a tensioning mechanism. A bridge support column is fixed to the bottom of the bridge, and two fixing mechanisms are respectively arranged on the outer sides of the bridge support columns. The quick-installation adjustable bridge reinforcement structure is provided with a tensioning mechanism, which drives the screw rod to rotate by rotating the driving block so that the screw rod can move inside the threaded groove, thereby changing the distance between the first tensioning rod and the second tensioning rod, so that the inclination angle of the support rod can be adjusted, and the support ball at the top of the support rod can be in close contact with the bottom of the bridge, thereby achieving the effect of strengthening the bridge support. There is no need to use a retractable hydraulic rod to reinforce the bridge support, which reduces the cost of making the reinforcement structure, and there is no need to use expansion bolts to connect the reinforcement structure and the bridge, which reduces the difficulty of disassembly and facilitates the construction of operators.

[0004] Based on the above, in the process of reinforcing the bottom of the bridge, the construction workers rotate multiple bolts and nuts in sequence, and then rotate the lead screws at both ends respectively to achieve support reinforcement of the bridge by the support balls and support rods. This requires the construction workers to repeat work, which increases their workload and also affects the work efficiency when positioning and installing the support reinforcement structure and the bottom of the bridge.
