The truss is a plane or space structure which is generally provided with triangular units and consists of straight rods, and the truss rod piece mainly bears axial tension or pressure, so that the strength of materials can be fully utilized, the material can be saved compared with a solid web beam when the span is large, the self weight is reduced, and the rigidity is increased. The truss has the advantages that the rod piece mainly bears tensile force or pressure, the function of materials can be fully exerted, materials are saved, and the structure weight is reduced. The planar trusses are of various types, but triangular trusses are used more often, namely, the internal space of the planar trusses is divided into a plurality of connected triangles by the transverse steel bars between the two longitudinal steel bars, and the stress distribution of the planar trusses of the structure is uniform. Lie in middle part divided reinforcing bar in this type of plane truss and have multiple production scheme, firstly form by the concatenation welding of a plurality of short reinforcing bars, but consuming time and wasting force, and hardly accomplish the height and level, secondly buckle a reinforcing bar repeatedly, such reinforcing bar wholeness is good, and is more stable than former reinforcing bar, more pleasing to the eye. However, the second type of steel bar cannot be continuously bent through the existing equipment, the angle of the continuous bent steel bar is not well controlled, the appearance is not attractive, and the discontinuous bending easily causes the steel bar to be broken in a stress way. The existing wave folding device has two types, one type is that the steel bar which is bent and passed through is continuously rotated by two staggered gear-shaped structures to form a wave structure, and the other type is that the metal rod is driven by a cylinder to bend the steel bar to form a wave shape. Both of these structures present problems. The first device is very efficient in production, but the gear-like structure of each size can only produce one wave shape, i.e. if the manufacturer needs to adjust the size and amplitude of the finished product, the whole gear-like structure needs to be exchanged, which undoubtedly increases the production cost. Compared with the first device, the second device can change the bending amplitude of the waves by controlling the amplitude of the cylinder, but the time consumption of each round trip of the cylinder is long, so that the production efficiency is poor, and meanwhile, the existing cylinder equipment is not provided with a reasonable reinforcing steel bar fixing device, so that the accuracy of a finished product is poor.

The device is through the rotation of movable ripples ware and rather than the crisscross fixed ripples ware cooperation reinforcing bar of buckling the passing through of movable ripples ware makes it form the wave structure, compares other two movable gear column structures, can improve the energy utilization, saves manufacturing cost. However, there is a case where the bending dimension is fixed, and it is necessary to exchange the movable wave breaker and the fixed wave breaker when a change in the structure of the finished product is required.
