Description

technical field [0001] The invention belongs to the field of building construction, and relates to an integrated automatic transmission, bending and welding device for the main reinforcement of a large-span box girder, and is especially suitable for bending and welding the main reinforcement of a large-span box girder for expressway construction. Background technique [0002] The steel structure has high strength, good plasticity and toughness, good ductility and other characteristics, which determine its own excellent seismic performance, and also makes steel structures widely used in high-rise buildings, highways, long-span space structures and bridges. Applications. [0003] The traditional steel structure manufacturing process mainly includes the steps of transmission, bending, welding and correction. Taking the main steel structure of the large-span box girder for expressway construction as an example, the steel bar with a length of 30 meters is generally required; but ...

Problems solved by technology

[0004] Traditional craftsmanship is difficult to meet the production requirements

Mainly manifested in: in the steel bar transmission step, because the steel bar is long and heavy, it is very laborious to drag and carry the heavy steel bar only manually

In the steel bar bending step, most of the existing operation methods use manpower to bend, and some thicker steel bars need manpower to cooperate with some simple equipment for bending processing when bending, which requires a lot of manpower, and there is no special The bending machine has led to a large amount of labor for the workers, there are irregularities, slow production efficiency, and low work efficiency, which has caused many problems in actual use and affected the actual use.

In the step of splicing the main reinforcement of the box girder, the traditional and common assembly methods are difficult to meet the requirements of complete matching of the two curved surfaces. After assembly, the curved surfaces are prone to irregularities, resulting in the inability to pair welding between adjacent curved surfaces, resulting in rework and waste. A large amount of production costs, but also reduces production efficiency; in the welding process of the main parts of the box girder, the traditional method for large steel structures is to directly weld the butt joints of the welding machine, but this welding method is difficult to meet the requirements of the joint parts of the main reinforcement of the box girder. Welding requirements for arc-shaped main welds, the shape of the welds is not beautiful, and the welding requirements are difficult to meet the standard requirements
