Description

Technical Field

[0001] The utility model relates to the field of box beam construction, in particular to a steel bar frame of a variable-section concrete box beam. Background Art

[0002] The prefabrication of box girders is to first tie and shape the box girder reinforcement, and then use the integral formwork to pour the box girder concrete. In order to improve the efficiency of box girder reinforcement tying, a steel bar tying jig is generally used on site to complete the box girder reinforcement tying work. The prefabricated box girder reinforcement tyres have various forms such as fixed type, vertical type, and simple type for small components.

[0003] The length of the existing steel bar binding jig is fixed and cannot be adjusted. It can only be used for box girder steel bar binding operations of one length. Different box girders require different steel bar binding jigs, which has a high investment cost. Different box girder inclinations require the setting of multiple binding jigs. When binding steel bars, scaffolding needs to be set up to fix the upper steel bars, which takes a long time. Therefore, in order to solve this problem, it is very necessary to design a steel bar jig for variable-section concrete box girders. Utility Model Content
