Description

Technical Field

[0001] This invention relates to providing an apparatus and method for continuous stirrups. Background Technology

[0002] In anchorage zones and lap lengths where larger diameter reinforcing bars are used, and when there are many parallel reinforcing bars in a row, such as in beam structures, a certain number of stirrups should be provided to prevent splitting and spalling of the concrete cover. The function of stirrups is to enhance shear strength and connect the main reinforcing bars and the compression zone concrete to work together. In addition, they are used to fix the position of the main reinforcing bars, forming a reinforcing cage within the beam. Simultaneously, stirrups can limit the development of internal cracks in the concrete, improving bond strength, and can also limit the width of cracks reaching the surface of the member, thereby improving bond strength.

[0003] Traditional stirrups are planar in form. For example, during the fabrication of a steel cage, planar stirrups are individually fixed to the main reinforcement bars using appropriate methods (e.g., welding, binding). However, the process of fixing a large number of stirrups to the main reinforcement bars is quite labor-intensive and time-consuming. Furthermore, because the stirrups are arranged separately, the spacing between adjacent stirrups after they are fixed to the main reinforcement bars may differ, potentially leading to variations in the structural strength of the steel cage. Therefore, how to efficiently fabricate a structurally reinforced steel cage has become an important issue in building and construction engineering. Summary of the Invention

[0004] Therefore, in order to solve the above problems, one embodiment of the present invention provides a method and equipment for manufacturing continuous stirrups, which can quickly produce multiple stirrups connected in sequence, thereby reducing the manpower and time required to fix the stirrups to the main reinforcement, and can maintain the spacing between adjacent stirrups to avoid variations in the structural strength of the steel cage.

[0005] According to some embodiments of the present invention, the continuous stirrup fabrication equipment and method are configured to operate on reinforcing bars having a planar structure. The planar structure has a continuously curved shape and includes a plurality of first portions arranged substantially parallel along the transverse axis, and a plurality of second portions connecting adjacent first portions along the transverse axis. The planar structure has opposing first ends and second ends in the longitudinal axis direction, and the planar structure is defined as a first side region near the first end, a second side region near the second end, and an intermediate region between the first side region and the second side region.

The jig includes an elongated jig body and a plurality of positioning members. The elongated jig body extends parallel to the transverse axis and is slidably disposed on the fixed platform in a longitudinal direction. The plurality of positioning members are disposed on the elongated jig body and configured to abut against a plurality of first portions of the reinforcing bar. The elongated mold is disposed adjacent to the front edge of the fixed platform and is movable relative to the fixed platform to bend upward against a plurality of first portions protruding from the front edge of the fixed platform. The plurality of bending devices are arranged at fixed intervals along the transverse axis, adjacent to the elongated mold, and substantially parallel to the elongated mold.

[0032] Figure 1 This diagram shows a continuous stirrup fabrication device 1 according to an embodiment of the present invention. According to an embodiment of the present invention, the continuous stirrup fabrication device 1 includes a base 10 and two first support plates 12. Figure 1 Only one first support plate 12 is shown, the other first support plate 12 is not shown), two rear brackets 13, two upper brackets 14, two front brackets 15, and two second support plates 16. Figure 1 (Only one second support plate 16 is shown, the other second support plate 16 is not shown), placement platform 17, fixing platform 20, multiple bending devices 30, long strip mold 35 and size positioning parts 40.

[0033] Two first support plates 12 are disposed on opposite sides of the base 10 in the horizontal direction (X-axis direction) and extend a predetermined height away from the base 10 to support the two upper supports 14 above them respectively. Two second support plates 16 are spaced apart from the two first support plates 12 in the vertical direction (Y-axis direction). The two second support plates 16 are disposed on opposite sides of the base 10 in the horizontal direction (X-axis direction) and extend a predetermined height away from the base 10 to support the placement platform 17 located above them. In other embodiments, the support plates 12 and 16 located on the same side of the base 10 are integrally formed to support the upper supports 14 and the placement platform 17, or three or more support plates are disposed on opposite sides of the base 10.

[0034] The two ends of the two rear supports 13 are inclinedly connected to the base 10 and the two upper supports 14 to enhance the structural stability of the two upper supports 14. Overall, the two upper supports 14 are stably supported by the two first support plates 12 and the two rear supports 13, with one end of each upper support 14 being adjacent to the placement platform 17 and extending away from the placement platform 17 along the longitudinal axis (Y-axis direction).

[0035] The fixing platform 20 is configured to support the reinforcing bars forming the continuous stirrups during the fabrication of the continuous stirrups. In some embodiments, the fixing platform 20 comprises a rectangular flat plate structure having a rear edge 21, a front edge 22, and two side edges 23, 24. The rear edge 21 is opposite to the front edge 22. The two side edges 23, 24 are respectively connected between the rear edge 21 and the front edge 22 and are opposite to each other. In some embodiments, the fixing platform 20 is disposed on the upper support 14, wherein the front edge 22 of the fixing platform 20 is disposed adjacent to the placement platform 17, and the two side edges 23, 24 are respectively disposed adjacent to the two upper supports 14. In some embodiments, the distance between the two side edges 23, 24 of the fixing platform 20 is greater than the distance between the two upper supports 14. Therefore, after the fixing platform 20 is disposed on the two upper supports 14, the two side edges 23, 24 of the fixing platform 20 protrude outward from the two upper supports 14 in the transverse direction (X-axis direction) (i.e., the side edges 23, 24 are spaced apart from the upper supports 14 by a distance).

[0036] In some embodiments, such as Figure 1 As shown, multiple bending devices 30 are arranged at fixed intervals along the horizontal axis (X-axis direction) on the placement table 17. The multiple bending devices 30 are positioned adjacent to each other between the front edge 22 of the fixed platform 20 and the elongated mold 35. Multiple positioning grooves corresponding to the shapes of the bending devices 30 can be pre-formed on the placement table 17, allowing the bending devices 30 to be precisely positioned at predetermined locations on the placement table 17.

[0037] Figure 2 This diagram shows a bending device 30 according to an embodiment of the present invention. In some embodiments, the bending device 30 includes a rectangular base 31, a connecting portion 32, and a bending positioning member 33. In some embodiments, such as Figure 2 As shown, the connecting part 32 is located at the corner of the rectangular base 31, and the bent positioning member 33 extends from the top of the connecting part 32 along a parallel line to the base 31 (and the parallel elongated mold 35). Figure 1 The bending positioning element 33 extends in the direction of (). The bending positioning element 33 may have an arc-shaped outer surface. However, it is understood that embodiments of the invention are not limited thereto. In other embodiments, the outer surface of the bending positioning element 33 may have any shape, such as a triangle, a quadrilateral, or any polygon.

[0038] refer to Figure 1A long strip mold 35 is configured to bend a reinforcing bar having multiple bends. In some embodiments, the long strip mold 35 is positioned on the side of the bending device 30 away from the fixed platform 20. The long strip mold 35 extends along the transverse axis (X-axis direction) and has a width substantially the same as the fixed platform 20 in the transverse axis (X-axis direction). The long strip mold 35 can be driven by an actuating device (e.g., a hydraulic rod, not shown) and thus rotated about a pivot 37 parallel to the transverse axis (X-axis direction). The top surface 36 of the long strip mold 35 can be a flat surface. Before the long strip mold 35 is driven, the top surface 36 can be at the same height as the top surface 25 of the fixed platform 20.

[0039] The dimensional positioning element 40 is configured to control the length of the reinforcing bar protruding from the front edge 22 of the fixed platform 20. In some embodiments, the dimensional positioning element 40 faces the front edge 22 of the fixed platform 20, and the dimensional positioning element 40 and the fixture 50 are located on opposite sides of the elongated mold 35. In some embodiments, the dimensional positioning element 40 is slidably mounted on the front support 15 relative to the elongated mold 35. In some embodiments, the dimensional positioning element 40 is an L-shaped plate structure extending along the transverse axis (X-axis direction) and includes a support portion 41 and a limiting portion 42 arranged perpendicularly to each other. The support portion 41 may be at the same height as the top surface 25 of the fixed platform 20, and the limiting portion 42 is located on the side of the support portion 41 away from the elongated mold 35.

[0040] Figure 3 This diagram shows a continuous stirrup fabrication apparatus 1 with a jig 50 according to an embodiment of the present invention. The jig 50 includes an elongated jig body 51, a plurality of positioning members, such as a plurality of first positioning members 52 and second positioning members 53, two slot structures 54, and a plurality of handles 55. In some embodiments, the elongated jig body 51 extends along a direction parallel to the transverse axis (X-axis direction), parallel to the front edge 22 of the fixed platform 20, and is slidably disposed on the fixed platform 20 along the longitudinal axis (Y-axis direction). The two slot structures 54 respectively connect the two ends of the elongated jig body 51 and slidably connect the two side edges 23, 24 of the fixed platform 20. In some embodiments, the handles 55 are disposed on the upper surface 512 of the elongated jig body 51 for the operator to grip and slide the jig 50 relative to the fixed platform 20.

[0041] The first positioning member 52 and the second positioning member 53 are configured to fix the position of the reinforcing bar during the fabrication of continuous stirrups. In some embodiments, the first positioning member 52 and the second positioning member 53 are disposed on the lower surface 51 of the elongated fixture body 51, and the elongated fixture body 51 is disposed above the top surface 25 of the fixing platform 20 via the first positioning member 52 and the second positioning member 53. That is, the lower surface 51 of the elongated fixture body 51 is spaced apart from the fixing platform 20 by a distance. In some embodiments, each of the first positioning member 52 and the second positioning member 53 corresponds to the bending device 30. In this way, after the reinforcing bar is placed on the fixing platform 20, the portion of the reinforcing bar extending in the longitudinal direction (Y-axis direction) will simultaneously come into contact with one of the first positioning member 52 and the second positioning member 53 by the bending device 30.

[0042] In some embodiments, such as Figure 3 As shown, the first positioning member 52 and the second positioning member 53 each have a length in the longitudinal direction (Y-axis direction), and each has a bent end at one end of the leading edge 22 of the adjacent fixing platform 20 that is skewed relative to the longitudinal direction (Y-axis direction), wherein the bending directions of the first positioning member 52 and the second positioning member 53 are opposite. Specifically, the first positioning member 52 bends toward the side edge 54, and the second positioning member 53 bends toward the side edge 53. In some embodiments, the first positioning member 52 and the second positioning member 53 are alternately disposed on the lower surface 51 of the elongated fixture body 51, and two adjacent first positioning members 52 and second positioning members 53 together form a flared structure. However, it is understood that the embodiments of the present invention are not limited thereto, and the arrangement order of the first positioning member 52 and the second positioning member 53 can be adjusted according to requirements. For example, as Figure 3 As shown, at one end of the adjacent side edge 23, two positioning members 53 are arranged continuously on the elongated fixture body 51 to apply a resisting force toward the steel bars of the side edge 23 closest to the fixed platform 20 during operation.

[0043] Please refer to Figure 3-11 According to some embodiments of the present invention, the method for fabricating continuous stirrups using continuous stirrup fabrication equipment 1 is described below:

[0044] like Figure 3 As shown, the method for fabricating continuous stirrups includes providing a jig 50 on a fixed platform 20. In some embodiments, after the jig 50 is disposed on the fixed platform 20, the slot structure 54 of the jig 50 slidably connects the two side edges 23, 24 of the fixed platform 20, and the first positioning member 52 and the second positioning member 53 of the jig 50 are respectively aligned with one of the plurality of bending devices 30 in the longitudinal direction (Y-axis direction).

[0045] In some embodiments, such as Figure 4 As shown, before using the continuous stirrup fabrication equipment to fabricate continuous stirrups, the long straight steel bar 60 is first processed through the bending equipment 80 to form a planar structure with a continuously bent portion. In some embodiments, the bending equipment 80 includes a bending device 81, a fixed block 82, and a movable block 83. The fixed block 82 and the movable block 83 are arranged in a straight line, wherein the movable block 83 can be bent along the following path: Figure 4 The bending device 81 rotates in the direction of the arrow shown, from the starting position (dashed box) to the driving position (solid box). The bending device 81 is positioned facing the end of the movable block 83 adjacent to the fixed block 82 and has an arc-shaped surface. The method of bending the reinforcing bar includes feeding the reinforcing bar into the bending device 80, causing the reinforcing bar 60 to simultaneously abut against the fixed block 82 and the movable block 83 located at the starting position, and then driving the movable block 83 along the direction shown by the arrow. Figure 4 Rotate in the direction of the arrow shown, and bend the reinforcing bar 60 using the bending device 81. Then, repeat the above steps multiple times to form a shape as shown. Figure 5 The planar structure shown is 600.

[0046] In some embodiments, the planar structure 600 includes a plurality of first portions 61, a plurality of second portions 62, and two end-bending structures 63. The plurality of first portions 61 are arranged substantially parallel along the transverse axis (X-axis direction) and each has an opposing first end 611 and a second end 612. The plurality of second portions 62 each connect two adjacent first portions 61 along the transverse axis (X-axis direction). The two end-bending structures 63 are respectively bent from the outermost first portion 61. For ease of description, in the following description, the region on the planar structure 600 adjacent to the first end 611 of the first portion 61 is referred to as the first side region 66, and the region on the planar structure 600 adjacent to the second end 612 of the first portion 61 is referred to as the second side region 67. The region located between the first side region 66 and the second side region 67 is referred to as the intermediate region 65. The first side region 66 and the second side region 67 may have the same length in the longitudinal axis (Y-axis direction), and their dimensions may be determined by the design of the continuous stirrups.

[0047] like Figure 6 As shown, the method for fabricating continuous stirrups further includes placing the planar structure 600 on the fixed platform 20, such that a first side region 66 protrudes from the front edge 22 of the fixed platform 20, and abutting a second portion 62 of the first side region 66 against the limiting portion 42 of the dimensional positioning member 40. Through the dimensional positioning member 40, the intersection of each first portion 61 and the middle region 65 is positioned below the corresponding bending positioning member 33. In some embodiments, the distance of the dimensional positioning member 40 relative to the elongated mold 35 can be adjusted according to the dimensions of the planar structure 600.

[0048] like Figure 7 As shown, the method for fabricating continuous stirrups further includes moving a jig 50 such that a plurality of positioning members 52, 53 of the jig 50 abut against a first portion 61 of the planar structure 600. In some embodiments, the jig 50 moves along the longitudinal axis (Y-axis direction) from a starting position ( Figure 6 ) was slid to the operating position ( Figure 7 During the aforementioned movement of the fixture 50, the second portion 62 of the second side region 67 is guided through the fixture 50 by the flared structure formed by adjacent first positioning members 52 and second positioning members 53. After the second portion 62 of the second side region 67 passes through the fixture 50, the adjacent first positioning members 52 and second positioning members 53 each abut against two first portions 61 connected by the corresponding second portions 62. In some embodiments, since the first positioning members 52 and second positioning members 53 each have curved ends, their ends extend in an arcuate curve in a direction away from the plurality of first portions 61 they abut.

[0049] In addition, such as Figure 7 As shown, the method for fabricating continuous stirrups further includes providing an elongated mold 35 along the transverse axis (X-axis direction) and having its top surface 36 abut against at least a portion of a first side region 66 of the planar structure 600. In some embodiments, before the first side region 66 is bent, the first side region 66 is subjected to the base 31 of the bending device 30 ( Figure 2 The top surface 36 of the elongated mold 35 and the supporting part 41 of the dimensional positioning component 40 provide common support.

[0050] like Figure 8 As shown, the method for fabricating continuous stirrups further includes actuating the elongated mold 35 to apply a pushing force to the first side region 66, causing the first side region 66 to bend upward relative to the fixed platform 20, at which point the planar structure 600 deforms into an intermediate structure 600'. In some embodiments, since the position of the first portion 61 of the planar structure 600 in the transverse direction (X-axis direction) is restricted by the first positioning member 52 and the second positioning member 53, the first portion 61 of the planar structure 600 does not wobble during the pushing process of the first side region 66 by the elongated mold 35. Therefore, the bent first portion 61 remains substantially parallel along the longitudinal direction (Y-axis direction). After bending the first side region 66 relative to the intermediate region 65, the jig 50 separates from the intermediate structure 600', and the intermediate structure 600' is temporarily removed from the continuous stirrup fabrication equipment 1.

[0051] like Figure 9 As shown, the method of making continuous stirrups further includes turning a section having an intermediate structure 600' and placing it on a fixed platform 20 such that a portion of the second side region 67 protrudes from the front edge 22 of the fixed platform 20 and is located below the bending positioning member 33.

[0052] like Figure 9 As shown, the method for fabricating continuous stirrups further includes bringing the elongated jig body 50 and its first positioning member 52 and second positioning member 53 abut against the bend 68 of the intermediate structure 600'. In some embodiments, the jig 50 is positioned along the longitudinal axis (Y-axis direction) from the starting position ( Figure 9 Slide to the operating position ( Figure 10 During the aforementioned movement of the fixture 50, the bent portion 68 of the intermediate structure 600' is guided by the flared structure formed by the adjacent first positioning member 52 and second positioning member 53 to enter between them. Subsequently, the adjacent first positioning member 52 and second positioning member 53 each abut against the first portion 61 corresponding to the bent portion 68. Driven by the fixture 50, the intermediate structure 600' continues to move along the longitudinal axis (Y-axis direction) until the second portion 62 of the second side section 67 abuts against the limiting portion 42 of the dimensional positioning member 40, as shown. Figure 10 As shown. At this time, the intersection of the second side region 67 and the middle region 65 in each first part 61 will be positioned below the bending positioning member 33. Furthermore, the second side region 67 is supported by the base 31 of the bending device 30. Figure 2 The top surface 36 of the elongated mold 35 and the supporting part 41 of the dimensional positioning component 40 provide common support.

[0053] like Figure 11 As shown, the method for fabricating continuous stirrups further includes actuating the elongated mold 35 to push the second side region 67, causing the second side region 67 to bend upward relative to the fixed platform 20 to form a continuous stirrup 600". In some embodiments, since the position of the first portion 61 of the intermediate structure 600' in the transverse direction (X-axis direction) is restricted by the first positioning member 52 and the second positioning member 53, the first portion 61 of the intermediate structure 600' does not wobble or shift during the pushing of the second side region 67 by the elongated mold 35. Therefore, the first portion 61 of the intermediate structure 600' after bending remains substantially parallel along the transverse direction (X-axis direction). In some embodiments, the method for fabricating continuous stirrups 600" further includes separating the jig 50 from the continuous stirrup after bending the second side region 67 and removing the continuous stirrup 600" from the continuous stirrup fabrication equipment 1.

[0054] Figure 12 This diagram shows a continuous stirrup fabrication device 1a according to an embodiment of the present invention. In this embodiment, it is related to... Figure 1-11The same components as those in the continuous stirrup fabrication equipment 1 will be designated with the same component symbols, and the characteristics of the components will not be described again. According to an embodiment of the present invention, the differences between the continuous stirrup fabrication equipment 1a and the continuous stirrup fabrication equipment 1 include: the fixed platform 20 of the continuous stirrup fabrication equipment 1 is replaced by the fixed platform 20a, and the fixture 50 of the continuous stirrup fabrication equipment 1 consists of multiple positioning components, such as a first positioning component 72, a second positioning component 73, etc. Figure 13 ) replaced.

[0055] In some embodiments, the fixing platform 20a is configured to support the planar structure 600 during the fabrication of continuous stirrups. In some embodiments, the fixing platform 20a and... Figure 1 The fixed platform 20 shown has a similar structure, the difference being that the fixed platform 20a further includes a first groove 70 and a second groove 71, which penetrate the fixed platform 20a. The first groove 70 and the second groove 71 each extend along the transverse axis (X-axis direction) and are parallel to the leading edge 22 of the fixed platform 20a, wherein the second groove 71 is located between the first groove 70 and the leading edge 22 of the fixed platform 20a.

[0056] Figure 13 This diagram shows a continuous stirrup fabrication device 1a according to an embodiment of the present invention after the positioning members 72 and 73 are installed. In some embodiments, a plurality of first positioning members 72 are disposed in a first groove 70 relative to a bending device 30 in the longitudinal direction (Y-axis direction). Furthermore, a plurality of second positioning members 73 are disposed in a second groove 71 relative to a bending device 30 in the longitudinal direction (Y-axis direction). Please refer to... Figure 15 After the planar structure 600 is placed on the fixed platform 20a, the first positioning member 72 and the second positioning member 73, which are respectively arranged relative to the same bending device 30, abut against the opposite sides of the first part 61 of the planar structure 600. However, it is understood that the embodiments of the present invention are not limited thereto. In some embodiments, the first groove 70 and the first positioning member 72 are omitted, and the first part 61 of the planar structure 600 is positioned only by the second positioning member 73.

[0057] refer to Figure 14In some embodiments, the first positioning member 72 includes a substrate 721, a positioning post 722, an extension 723, and a fixing member 724. The substrate 721 spans over the first trench 70 and is mounted on the top surface 25 via the fixing member 724 (e.g., a screw or bolt). The positioning post 722 is disposed above the substrate 721 and has a cylindrical structure. The extension 723 is disposed below the substrate 721 and extends into the first trench 70 to facilitate the positioning of the first positioning member 72 within the first trench 70. In some embodiments, the structural features of the second positioning trench 73 are the same as or similar to those of the first positioning trench 72, and therefore will not be repeated.

[0058] Please refer to Figure 13 , 15 -18. According to some embodiments of the present invention, the method for fabricating continuous stirrups using continuous stirrup fabrication equipment 1a is described below:

[0059] like Figure 13 As shown, the method for fabricating continuous stirrups includes providing and fixing a plurality of first positioning members 72 in a first groove 70 of a fixing platform 20, and fixing a plurality of second positioning members 72 in a second groove 71 of the fixing platform 20. In some embodiments, the step of fixing the second positioning members 72 is omitted.

[0060] like Figure 15 As shown, the method for fabricating continuous stirrups further includes placing the planar structure 600 on the fixed platform 20a, such that the first side region 66 protrudes from the front edge 22 of the fixed platform 20a, and that the second portion 62 of the first side region 66 abuts against the limiting portion 42 of the dimensional positioning member 40. Through the dimensional positioning member 40, the intersection of each first portion 61 and the middle region 65 is positioned below the corresponding bending positioning member 33. Furthermore, when the planar structure 600 is placed on the fixed platform 20a, the opposite sides of each first portion 61 of the planar structure 600 abut against the corresponding first positioning member 72 and second positioning member 73, respectively.

[0061] In addition, such as Figure 15 As shown, the method for fabricating continuous stirrups further includes providing an elongated mold 35 along the transverse axis (X-axis direction) and having its top surface 36 abut against at least a portion of a first side region 66 of the planar structure. In some embodiments, before the first side region 66 is bent, the first side region 66 is subjected to the base 31 of the bending device 30 ( Figure 2 The top surface 36 of the elongated mold 35 and the supporting part 41 of the dimensional positioning component 40 provide common support.

[0062] like Figure 16As shown, the method for fabricating continuous stirrups further includes actuating an elongated mold 35 to push a first side region 66, causing the first side region 66 to bend upward relative to the fixed platform 20a, thereby transforming the planar structure 600 into an intermediate structure 600'. In some embodiments, since the position of the first portion 61 of the planar structure 600 in the transverse direction (X-axis direction) is restricted by the first positioning member 72 and the second positioning member 73, the first portion 61 of the planar structure 600 does not wobble or shift during the pushing of the first side region 66 by the elongated mold 35. Therefore, the plurality of first portions 61 after bending remain substantially parallel along the transverse direction (X-axis direction). After bending the first side region 66 relative to the intermediate region 65, the intermediate structure 600' is temporarily removed from the continuous stirrup fabrication equipment 1a.

[0063] like Figure 17 As shown, the method of fabricating continuous stirrups further includes turning the intermediate structure 600' and placing it on the fixed platform 20a, such that the second side region 67 protrudes beyond the leading edge 22 of the fixed platform 20a. In some embodiments, such as Figure 17 As shown, the intermediate structure 600', after being turned and placed on the fixed platform 20a, has its second side region 67 subjected to the base 31 of the bending device 30. Figure 2 The top surface 36 of the elongated mold 35 and the supporting portion 41 of the dimensional positioning member 40 provide joint support. In some embodiments, such as Figure 17 As shown, after the intermediate structure 600' is placed on the fixed platform 20a, the bent portion 68 of the intermediate structure 600' abuts against a plurality of second positioning members 73 and separates from the first positioning member 72.

[0064] like Figure 18 As shown, the method for fabricating continuous stirrups further includes actuating an elongated mold 35 to push the second side region 67 of the intermediate structure 600', causing the second side region 67 to bend upward relative to the fixed platform 20a to form a continuous stirrup 600". In some embodiments, since the position of the first portion 61 of the intermediate structure 600' in the transverse direction (X-axis direction) is restricted by the second positioning member 73, the first portion 61 of the intermediate structure 600' does not wobble or shift during the pushing of the second side region 67 by the elongated mold 35. Therefore, the multiple first portions 61 after bending remain substantially parallel along the longitudinal direction (Y-axis direction). In some embodiments, the method for fabricating continuous stirrups 600" further includes removing the continuous stirrup 600" from the continuous stirrup fabrication equipment 1a after bending the second side region 67.
