Description

The present invention relates to a reinforcing bar fixed device applied to a rectangular helical cage forming device.

As the demand for the structural strength of various buildings increases, the design strength provided by the frame composed of helical rebars is now regarded as important in structural design in the engineering field. The so-called spiral stirrup refers to a stirrup in which a spiral reinforcing bar that is bent to form a continuous spiral body is combined with the main muscle, and has an effect of providing fixing and shear strength of the position of the main muscle. The cross-sectional shape of the helical rebar is adjusted based on the actual design, and many circular and rectangular shapes are seen. In addition to being widely used as a stirrup for structures such as beams, it is also used for large or specially designed beam structures, with a helical rebar as a main frame or combined with a steel frame. In particular, in the precast structure, a large amount of helical rebar is applied.

However, many of the conventional methods for manufacturing a helical rebar described above use a rebar bending machine. First, a straight reinforcing bar is gradually bent to form a reinforcing bar coil without a gap, and then a front end and a rear end of the reinforcing bar coil are pulled by a machine to open a gap. There is room for improvement in both efficiency and control of the manufacturing method. In the design structure with a spiral rebar as the main frame, the points that are further bound by human power or welded to the rebar by spot welding are installed on the sides of the spiral rebar, forming a spiral rebar rod, It was not reasonable in a situation where labor and time were required, and the demand for spiral reinforcing bars increased day by day.

FIG. 1 is an external perspective view showing the assembly of a conventional rectangular helical cage forming apparatus, which is used to manufacture a rectangular helical cage 100 having a plurality of spaced spirals. A conventional rectangular spiral cage forming apparatus 200 includes a first rotating part 210, a second rotating part 220, a central rotating part 230, a plurality of axially wound reinforcing bar winding parts 233, and a reinforcing bar bending apparatus 400. Is provided. The reinforcing bar 500 is inserted into the central rotating part 230 from the reinforcing bar insertion side 232, and the reinforcing bar bending device 400 presses the reinforcing bar 500 and is interlocked with the rotation of the central rotating part 230 to be engaged with the reinforcing bar winding part 233 in the axial direction. The The first rotating unit 210 and the central rotating unit 230 are arranged in parallel, and the first rotating unit 210 is displaced outward along the axial direction 900 with respect to the central rotating unit 230. A plurality of rebar winding portions 233 in the axial direction are provided around the periphery 234 of the central rotation portion 230, and the rebar winding portions 233 and the first rotation portion 210 in the respective axial directions are detachably connected. The second rotating unit 220 is installed on one side of the central rotating unit 230 different from the first rotating unit 210 with respect to the central rotating unit 230 and is detachably connected to the reinforcing bar winding unit 233 in each axial direction. The second rotating unit 220, the central rotating unit 230, and the first rotating unit 210 are arranged side by side in a manner that they are displaced in synchronization with the first rotating unit 210 along the axial direction 900. When the second rotating part 220 and the first rotating part 210 are synchronously displaced along the axial direction 900, the distance between the second rotating part 220 and the central rotating part 230 is such that the first rotating part 210 is outside. It is shortened by being displaced toward.

As shown in FIG. 1, the rectangular helical cage forming device 200 further includes an advance device 300 installed in the first rotating unit 210 and is displaced by the method of being displaced along the axial direction 900. The rotating part 210 is interlocked, and the rebar winding part 233 in the axial direction is interlocked and displaced along the axial direction 900. When the first rotation unit 210 is interlocked by the advance device 300 and displaced outward with respect to the central rotation unit 230 in the axial direction 900 of the slide (not shown), the first rotation unit 210 performs the first rotation. The rebar winding portions 233 in the axial direction installed in the portion 210 are interlocked and moved through the cross-shaped groove 231 of the central rotating portion 230 in synchronization on the axial direction 900 of the slide (not shown). The When the first rotating unit 210 is interlocked by the advance device 300, the reinforcing bar bending device 400 gradually presses the reinforcing bar 500 and engages the reinforcing bar winding unit 233 in each axial direction, thereby leaving a plurality of intervals. A rectangular helical cage 100 having a spiral is formed. After the formation of the rectangular spiral cage 100, the axial rebar winding part 233 narrowly mounted in the cross-shaped groove 231 of the central rotating part 230 is moved along the radial direction, and the first rotating part 210 The axial rebar winding part 233 narrowly mounted in the cross-shaped groove tank 221 and the cross-shaped groove tank 221 of the second rotating part 220 is displaced synchronously along the radial direction, thereby forming a rectangular spiral shape. The cage 100 is loosened.

FIG. 2 is an operation diagram for removing the rectangular helical cage from the rectangular helical cage forming apparatus shown in FIG. When the axial rebar winding part 233 is displaced along the radial direction and the rectangular helical cage 100 is loosened inward, the first rotating part 210 is separated from the central rotating part 230 toward the outside. Separated from these axial rebar winding portions 233, at the same time, the axial rebar winding portion 233 is confined to the second rotating portion 220, and away from the central rotating portion 230, the rectangular helical cage 100 is removed. It is. When the rectangular helical cage 100 is formed to a required size and length, the rebar 500 is cut by the on-site supervisor, and the rebar winding part 233 in the axial direction is controlled to face inward. The rectangular helical cage 100 is removed by scaling, and the rectangular helical cage 100 is placed on the lifting plate 240.

However, the reinforcing bars deform due to elasticity (temporary) and plasticity (permanent). That is, the original shape is recovered after being released from the elastic deformation, but the original shape cannot be recovered by plastic deformation. As shown in FIG. 2, the rectangular helical cage 100 formed by the above-described conventional rectangular helical cage forming apparatus is less elastic due to plastic deformation at the corner 105 of the rectangular helical cage 100, and is elastic. Because of the large amount of recovery caused by, it affected the rebar form.

Therefore, the present inventor considered that the above-described drawbacks could be improved, and as a result of intensive studies, the present inventor came up with a proposal for the present invention to improve the problem reasonably and effectively.
