Description

Technical Field

[0001] The present application relates to the technical field of prefabricated box girder reinforcement, and in particular to a mechanized reinforcement insertion device for a prefabricated box girder intersection. Background Art

[0002] As a common bridge structure, box girders are widely used in various bridge projects. Prefabricated box girders refer to bridge structures that are processed and manufactured in factories or prefabrication yards and then transported to the construction site for installation. Prefabricated box girders have the following advantages:

[0003] 1. Controllable quality: Standardized production in factories or prefabrication yards can effectively control the quality and precision of components and improve the overall quality of the bridge;

[0004] 2. High construction efficiency: The construction period of prefabricated box beams is short and is not restricted by factors such as on-site weather and seasons, which can speed up the progress of the project;

[0005] 3. High safety: During the factory production process of prefabricated box girders, advanced welding, anti-corrosion and other processes can be used to improve the durability and safety of the bridge.

[0006] In order to improve the bearing capacity of the box girder and ensure its safety, stirrups need to be installed on the box girder. The function of spiral stirrups is to evenly distribute the load to each stirrup, thereby reducing the possibility of deformation and cracks in the box girder. At the same time, stirrups strengthen and stabilize the box girder, enabling it to withstand greater loads.

The above traditional cross reinforcement insertion at the corner of the prefabricated box beam has the following disadvantages:

[0008] ①It needs to be inserted manually one by one;

[0009] ② Manual positioning welding or binding is required, and the construction progress is difficult to guarantee;

[0010] ③Low efficiency and high labor demand.
