Apparatus and method for manufacturing continuous stirrup

A method for manufacturing a continuous stirrup, comprising:

• bending a rebar to form a planar structure, wherein the planar structure has a wavy shape and includes a plurality of first segments being disposed along a transverse orientation and substantially parallel along a longitudinal orientation and a plurality of second segments extending along the transverse orientation and alternatively connecting ends of two adjacent first segments, and the planar structure has a first end and a second end opposite to the first end in the longitudinal orientation, wherein the planar structure is defined as a first lateral region proximate to the first end, a second lateral region proximate to the second end, and an intermediate region between the first lateral region and the second lateral region;
• providing a platform which comprises a first groove and a second groove formed therein, wherein the first groove and the second groove are substantially parallel and extend along the transverse orientation, and the second groove is located between the first groove and a front edge of the platform;
• fixing a plurality of first positioning members in the first groove of the platform;
• placing the planar structure on the platform to abut the first segments of the planar structure against the first positioning members and extend the first lateral region from a front edge of the platform;
• providing an elongated mold that extends along the transverse orientation in such a manner that the elongated mold is able to abut against at least a portion of the first lateral region of the planar structure;
• impelling the elongated mold to abut against the first lateral region so that the first lateral region is bent upward relative to the platform to form an intermediate structure from the planar structure;
• fixing a plurality of second positioning members in the second groove of the platform;
• flipping the intermediate structure to have the bent portions of the intermediate structure abutted against the second positioning members and extend the second lateral region from the front edge of the platform;
• and
• impelling the elongated mold to abut against the second lateral region so that the second lateral region is bent upward relative to the platform.

• and
• a plurality of positioning members disposed on the elongated body and is configured to abut against the first segments of the rebar;
• an elongated mold disposed adjacent to the front edge of the platform and being movable relative to the platform so as to abut against the first segments extending from the front edge of the platform and bend upwards relative to the first segments;
• and
• a plurality of bending members arranged along the transverse orientation and spaced apart from each by a predetermined distance, the bending members being adjacent and substantially parallel to the elongated mold.
