Description

Technical Field

[0001] The present invention relates to the field of construction machinery, and particularly to a processing device for the abdominal steel bar frame of precast box girders. Background Art

[0002] A box girder is a type of beam in bridge engineering. The inside of the box girder is hollow, and there are flanges on both sides of the upper part, similar to a box, hence the name. Box girders of reinforced concrete structures are divided into precast box girders and cast-in-place box girders. The precast box girders prefabricated in an independent site can be erected after the lower works are completed in combination with a bridge erecting machine, which can accelerate the project progress and save the construction period; cast-in-place box girders are mostly used for large continuous bridges. Commonly classified by materials, there are mainly two types, one is the prestressed reinforced concrete box girder, and the other is the steel box girder. Among them, the prestressed reinforced concrete box girder is constructed on site. In addition to longitudinal prestress, some also have transverse prestress; the steel box girder is generally processed in a factory and then transported to the site for installation, which can be a fully steel structure or a partial structure with a reinforced concrete paving layer.

[0003] The abdominal steel bar frame for precast box girders includes longitudinally placed longitudinal steel bars and transversely placed transverse steel bar frames. Currently, in the construction of precast box girders, the steel bar materials at the bottom and web of the box girder are basically laid manually, with low construction efficiency, a large number of manual inputs, inconvenient construction, high labor intensity of workers, slow construction progress, and thus increased construction cost. Moreover, the longitudinal steel bars are fixedly connected to the transverse steel bar frames. However, currently, the longitudinal steel bars are generally straightened manually and then placed, and there is no special equipment for stretching the ends of the longitudinal steel bars, which will cause the longitudinal steel bars to be not straight after the abdominal steel bars of the box girder are processed.
