Problems solved by technology
At present, the process of binding the steel bars of the prefabricated box girder roof is generally completed in the formwork of the box girder. The defect of this binding method is that the prefabricated box girder generally uses the shaped formwork, and the workers occupy the beam for a long time when binding the roof steel bars. Pedestal and box girder formwork, and often due to steel bar spacing and fixing problems, the binding accuracy is low and the binding speed is slow, which affects the construction period and quality

The invention provides a movable prefabricated box girder top plate steel bar binding jig and a using method. The jig comprises a support, a toothed plate and a positioning assembly, wherein mountingplates are arranged on the tops of the two sides of the support, the toothed plate is vertically arranged on the mounting plates through the positioning assembly; and the positioning assembly comprises positioning nuts, positioning sleeves and a bolt rod, wherein the positioning nuts are arranged on the toothed plate at intervals, the positioning sleeves are arranged on the mounting plates at intervals and are arranged in a mode of corresponding to the positioning nuts, the bolt rod is an L-shaped bending rod and is matched with the positioning nuts and the positioning sleeves. According to the jig and the method, the steel bar binding precision can be improved, the construction speed is accelerated, meanwhile, the time for occupying a girder manufacturing pedestal and a box girder form can be greatly shortened, the safety is high, and the economic benefit is good.
Description
technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a steel bar binding mold for a movable prefabricated box girder roof and a method for using it. Background technique [0002] With the rapid development of high-speed railways and expressways, prefabricated box girder construction technology is widely used in order to save construction period. At present, the process of binding the steel bars of the prefabricated box girder roof is generally completed in the formwork of the box girder. The defect of this binding method is that the prefabricated box girder generally uses the shaped formwork, and the workers occupy the beam for a long time when binding the roof steel bars. The pedestal and box girder formwork, and often due to steel bar spacing and fixing problems, the binding accuracy is low and the binding speed is slow, which affects the construction period and quality. Contents of the invention [0003] The ...
