Description

Technical Field

[0001] The utility model belongs to the technical field of engineering accessories, and in particular relates to a prefabricated small box girder reinforcement binding cradle. Background Art

[0002] Prefabricated small box beams are box beams prefabricated in factories. These box beams are usually used in bridges, buildings or other structures to meet specific design requirements and technical specifications. Prefabricated small box beams are part of the building structure. During the production process, steel bars are usually set inside to increase strength and support. Therefore, during the production of prefabricated small box beams, steel bar tyre tyre frames are used to tie and support the steel bars. This can ensure that the steel bars can be in the correct position and meet the design requirements when pouring concrete.

[0003] Since prefabricated small box girders are produced inside the factory, they are generally set as spliced ​​structures for the convenience of transportation and other factors. After the prefabricated small box girders are transported to the appropriate location, the staff will carry out the splicing operation and adjust the tire frame to the appropriate position to meet the steel bar binding requirements. The existing prefabricated small box girders are generally connected and installed by bolts or welding, which is not only complicated to operate, but also when the staff adjusts the tire frame position, they need to adjust the inner tire frame of each prefabricated small box girder separately, which leads to low construction efficiency of the staff.
