Prefabricated box girder steel bar binding and positioning jig frame

Abstract

The invention discloses a prefabricated box girder steel bar binding and positioning jig frame which comprises first bottom plates and a second bottom plate. The two first bottom plates are arranged,and multiple supporting pillars which are arranged at equal intervals are welded to the tops of the first bottom plates. Fixing bars are fixed to the tops of the supporting pillars. Rolling grooves are formed in the tops of the fixing bars, and moving blocks are arranged above the fixing bars. Wheels are arranged at the bottoms of the moving blocks, and the wheels are installed in the rolling grooves in a rolling manner. A first casing pipe is arranged between the two moving blocks, and first sliding rods are connected in the two ends of the first casing pipe in a sliding and sleeved manner. The ends, back to each other, of the two first sliding rods are fixed to the moving blocks on the two sides, a sliding block is connected to the outer portion of the first casing pipe in a sliding andsleeving manner, and a lifting device is installed at the bottom of the sliding block. By means of the prefabricated box girder steel bar binding and positioning jig frame, position adjustment can beconducted on a steel bar, the labor intensity is greatly lowered, and operation convenience is improved.

Description

technical field [0001] The invention relates to the technical field of tire frame positioning, in particular to a prefabricated box girder steel bar binding positioning tire frame. Background technique [0002] Since the binding of the steel skeleton is the most workload, the most cumbersome and the longest time-consuming in the prefabricated box girder production operation, it is an important link in the box girder prefabrication. The traditional prefabricated box girder reinforcement is bound directly on the girder pedestal. Due to factors such as the dispersion of the beam pedestal, it takes time and effort to transport the semi-finished steel bars, the pass rate of the steel bar cover is low, the line shape of the steel bar skeleton is poor, and the spacing between the steel bars is uneven. , The steel skeleton is polluted by the release agent of the steel plate of the controlled beam pedestal, and the pedestal has a long turnover period. The quality and speed of tradit...

Problems solved by technology

The traditional prefabricated box girder reinforcement is bound directly on the girder pedestal. Due to factors such as the dispersion of the beam pedestal, it takes time and effort to transport the semi-finished steel bars, the pass rate of the steel bar cover is low, the line shape of the steel bar skeleton is poor, and the spacing between the steel bars is uneven. , The steel skeleton is polluted by the release agent of the steel plate of the controlled beam pedestal, and the pedestal has a long turnover period.

The quality and speed of traditional prefabricated box girder reinforcement binding often restrict the construction progress of on-site prefabricated box girders; at the same time, during the construction process, when the steel bars need to be adjusted, multiple people need to lift them up, and the operation is very troublesome. Therefore, we propose a Prefabricated box girder reinforcement binding positioning tire frame
