Background technique

At present, many large-space public buildings use metal roofs, and many of them have broken away from the traditional horizontal plane shape, showing a curved and arc shape, and the indoor floor of such building roofs mostly use profiled steel plates, which can be used for both As the structural load-bearing layer of the metal roof structure layer, it can also take into account the decorative ceiling effect of the building interior.

The profiled steel plates on the market generally use flat bottom plates. Even if there is a bending arc shape requirement, due to the material properties of the profiled steel plates, buckling deformation is likely to occur after bending to form a curved arc, so the straight plate folding line fitting is generally used. However, the use of straight-board polyline fitting will directly affect the interior effect of the building, lose its aesthetics, and reduce the quality of the entire building.

Therefore, there is an urgent need for a device that facilitates the formation of curved arcs for profiled steel plates. Based on this, this case was born.
