Technical Field

[0001] The present invention relates to the technical field of construction, and particularly relates to a steel bar truss processing device and a processing method thereof. Background Art

[0002] A steel bar truss is a truss structure composed of steel bars, which is widely used in construction projects. For example, it is used in the roof systems of large-span buildings such as industrial factories and warehouses to bear the roof load and transfer it to the supporting structure. At the same time, it can be used as a new type of floor formwork component to jointly form the floor structure of a building with materials such as concrete. During the construction stage, it bears the wet concrete and construction load, and serves as the stress-bearing steel bars of the floor during the use stage. A steel bar truss generally consists of one upper chord bar, two lower chord bars, and two web bars. The web bars are wavy and are used to connect the upper chord bar and the lower chord bars.
