[Prior Art] With the improvement of structural strength requirements of various buildings, the design strength provided by the skeleton composed of spiral steel bars has been paid attention to the structural design of today's engineering circles. The so-called spiral stirrup refers to the spiral reinforcement which is bent into a continuous spiral as the stirrup with the main tendon, which has the function of fixing the main tendon position and providing shear strength. The cross-sectional shape of the spiral steel bar can be adjusted according to the actual design. The more common ones are round and rectangular. In addition to the extensive use of stirrups for structures such as beams and columns, in some large or specially designed beam-column structures, spiral steel bars are also used as skeleton bodies or in conjunction with steel skeletons; especially in concrete structures. Spiral steel bars are used in a large number of applications. Traditionally, the manufacturing method of the sill-reinforced steel bar is mostly the use of the curved rib II, and the straight steel rib is gradually bent into the ferrule of the steel without the spacing, and then the head of the reinforcing rib is pulled by the machine to produce the (four) distance. This - the efficiency and spacing control of the production method has room to change the lips. In the structure of the use of steel bars for the riding frame field, the side of the spiral gluten is placed in the manner of manual binding or brazing to form a spiral reinforcing cage, which requires more labor and labor.

In the preferred embodiment, the third angle and the fourth angle are between 0 and 20 degrees, respectively, and the design requirements and structural strength of the sill should be different to form a tighter Pitch. 7 shows that the present invention simultaneously provides a method for forming a screw steel. Figure 12 200838637 is the step of the spiral_New_ method of the invention. No, f first face 91G, loaded: shape loading, 4! heart..., ... point screw% steel wheel welding / copper rib wheel welding forming device containing a plurality of 'point rib holes arranged by the rotating device Set in the wheel-shaped rotation part, for each point of the ribs to wear the second screw _ rib wheel welding forming device of the third Qiu 于 3 in the pinch ^ ★ ^ 卩 brother -% between the moving parts, the wheel of the department can be fresh - the rotating part And the second face synchronization to live: ί wheel welding (four) into the step further includes installing the point ribs in the wheel-shaped rotation part to the first-angle ^ rotation part, which can be rotated relative to the side of the rib and the angle between the brothers At the angle between the younger brother and the second angle, the ribs are placed in contact with the stirrups. Steps 920 and 930 are performed, and the ribs are extended from the rib side of the spiral rebar welding forming device, and the f-shaped ribs surround the wheel welding unit. The bending step described above further includes bending the reinforcing bar by the rotation of the rotating wheel-shaped rotating portion, and the wheel-shaped rotating portion includes a power unit that can supply power to rotate the wheel-shaped rotating portion and the wheel welding unit. The brewing is carried out in step 94, and the wheel welding unit is advanced in the direction of the pitch to generate the pitch. The foregoing advancement step 94 further includes engaging the advancement of the reinforcing bar to simultaneously advance the wheel welding unit; and the aforementioned pitch generating step further comprises outputting the reinforcing bar to the reinforcing bar straightener, and the reinforcing bar straightener has a pitch level adjusting device 'adjustable reinforcing bar The input position on the rib side and the distance between the pitches. Finally, step 950 is performed to weld the stirrups to each of the ribs to form a spiral cage. When the reinforcing bar extends from the side of the rib into the feeding rotating device, the wheel-shaped rotating part 13 200838637, the rounded reinforcing bar forms a stirrup around the rim unit and is connected with the point rib, and the wheel welding device cooperates with the propulsion device to interlock the first rotating portion along the axis In the action of displacement, the stirrups and the tendons are gradually welded to form a spiral reinforcing cage. The foregoing wheel welding step further comprises providing an electrode alloy wheel in the wheel-shaped rotating portion for use with the wheel welding device. When the stirrup contacts the rib, the electrode alloy disk is instantaneously discharged and welded. The present invention has been described by the above-described related embodiments, but the above embodiments are merely examples for implementing the present invention. It is to be understood that the disclosed embodiments do not limit the scope of the invention. On the contrary, the spirit of the invention and the modifications and equivalents thereof are included in the scope of the invention.
