[Effects of the Invention]

[0006] According to this invention, a coiled steel rod straightening assist device is provided that allows the number of coiled steel rods suspended from a cantilever beam to be increased as needed. [Brief explanation of the drawing]

[Figure 7] Figure 7 is a conceptual diagram illustrating a method of rust removal in which, in the embodiment shown in Figure 5 in which the coiled steel rod X is held, the support member 4 is moved to a position where the other end 2B of the rod-shaped member 2 can be attached and detached, and the lower side of the other end 2B of the rod-shaped member 2 is placed on the support jig 4d from the short side, and rust removal is performed in that state. [Modes for carrying out the invention]

[0008] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Each figure shows mutually orthogonal XYZ axes to determine direction. As shown in Figures 1, 2, 3, and 4, the coiled steel bar straightening assist device 1 according to this embodiment comprises a rod-shaped member 2, a fixing member 3, a support member 4, and a movable member 5. Coiled steel bar X is an annular steel material formed by winding a rod-shaped steel material into a coil. The rod-shaped member 2 extends horizontally (in both directions of the arrows roughly in the X direction) and supports the inner circumference X1 side of the coiled steel rod X, holding it in a suspended state in the diametrical direction X2.

[0009] The fixing member 3 fixes one end 2A of the rod-shaped member 2 and maintains the suspended state. One end 2A of the rod-shaped member 2 is fixed to the fixing member 3 so as to allow movement of the other end 2B of the rod-shaped member 2 in the vertical direction (Z direction in the figure). The support member 4 detachably supports the other end 2B of the rod-shaped member 2. The movable member 5 is configured to move back and forth between a position where the support member 4 can be attached and detached (hereinafter referred to as the first position) and a position where the other end 2B is detached (hereinafter referred to as the second position).

[0010] When the support member 4 is in the second position, the bar-shaped member 2 forms a cantilever beam. However, as the number of coiled steel bars W to be hung increases, inevitably, the other end 2B side of the bar-shaped member 2 also needs to be hung. Therefore, the weight applied to the other end 2B side of the bar-shaped member 2 increases. Accordingly, in that case, by moving the support member 4 to the first position and supporting the other end of the bar-shaped member 2, the stability of the bar-shaped member 2 can be maintained even when the weight increases. Therefore, since the support member 4 and the moving member 5 are provided in the coiled steel bar correction assisting device 1 according to the present embodiment, the number of coiled steel bars hung on the cantilever beam can be increased as needed.

[0011] It further has a base frame 6 extending in a direction parallel to the horizontal direction (both directions of the arrow in the approximate X direction) below the bar-shaped member 2 (the direction of the arrow opposite to the Z direction in the figure). A fixing member 3 is fixed to one end 6A of the base frame 6, and a moving member 5 is preferably fixed to the other end 6B of the base frame 6. By doing so, the bar-shaped member 2, the fixing member 3, the support member 4, the moving member 5, and the base frame 6 can be integrated. Accordingly, the coiled steel bar correction assisting device 1 according to the present embodiment can be made portable.

[0012] [[ID=十二]]The bar-shaped member 2, the fixing member 3, the support member 4, the moving member 5, and the base frame 6 are made of steel from the viewpoint of the weight of the coiled steel bar to be hung, etc., and have a thickness, length, structure, etc. that can sufficiently hold the coiled steel bar to be hung on the bar-shaped member 2.

[0013] The bar-shaped member 2 is, for example, composed of a cylindrical body. The horizontal length is, for example, 2 mm, the width of the outer diameter in the short direction is, for example, 12 cm, and the difference between the outer diameter and the inner diameter (the thickness of the cylindrical body in the short direction) is, for example, 3 cm.

[0014] The fixing member 3 is composed of, for example, a plate structure 3A composed of a plurality of plates with a rectangular cross section, and a fixing jig group 3B that is fixed on the plate structure 3A and fixes the bar-shaped member 2 from the short direction.

[0015] As shown in FIG. 3, the plate structure 3A has a base material 3Aa. Further, between the center line C in the longitudinal direction of the base material 3Aa and the outer peripheral ends O1, O2, there are a pair of column members 3Ab, 3Ab extending in the vertical direction (the direction of the arrow in the Z direction) about the center line C as an axis from R / 2, R / 2.

[0016] In addition, in the vicinity of the center line 3AbC in the longitudinal direction of the pair of column members 3Ab, 3Ab (in the drawing, above the center line 3AbC (the direction of the arrow in the Z direction; hereinafter referred to as the central part), on the outer surface), there are a pair of reinforcing members 3Ad1, 3Ad1 connecting the outer peripheral ends O1, O2 of each of the base material 3Aa, and a connecting member 3Ad2 connecting the pair of column members 3Ab, 3Ab to each other on the inner surface of the central part.

[0017] Also, there are two semi-plate structures 3Ae having the base material 3Aa, the pair of column members 3Ab, 3Ab, the pair of reinforcing members 3Ad1, 3Ad1, and the connecting member 3Ad2 in the longitudinal direction of the rod-shaped member 2, and these two semi-plate structures 3Ae, 3Ae are arranged substantially parallel in the vertical direction (the direction of the arrow in the Z direction). A flat plate 3c is fixed to both upper surfaces of the two semi-plate structures 3Ae, 3Ae arranged substantially parallel. Further, the connecting members 3Ad2, 3Ad2 (in FIG. 1, one connecting member 3Ad2 is not shown due to the perspective view relationship) connecting the opposing column members 3Ab, 3Ab of the two semi-plate structures 3Ae, 3Ae arranged substantially parallel in the vertical direction (the direction of the arrow in the Z direction) at the central part constitute the plate structure 3A.

[0018] The fixing jig group 3B has two fixing jigs 3B1 arranged in the longitudinal direction of the rod-shaped member 2 for detachably fixing the rod-shaped member 2 from the short side direction with a lever 3Ba. The rod-shaped member 2 is arranged by being inserted into and fixed within these two fixing jigs 3B1.

[0019] The support member 4 consists of a rectangular plate-shaped flat plate (lower plate) 4a, four column members 4b, 4b, 4b, 4b with one end face fixed to the four right-angle (90°) corners of the upper surface 4a1 of the flat plate 4a, extending vertically (in the direction of the arrow in the Z direction) from the four corners, and connecting members 4c, 4c, 4c, 4c that connect the four column members 4b, 4b, 4b, 4b ((In Figure 1, the center line 4bc of the column members 4b, 4b on the far side of the paper, opposite to the column members 4b, 4b on the near side of the paper, is not shown due to the perspective view), which are provided along the longitudinal centerlines 4bC, 4bC, 4bC, 4b ((In Figure 1, the centerline 4bc of the column members 4b, 4b on the far side of the paper, opposite to the column members 4b, 4b on the near side of the paper, is not shown) and connect the four column members 4b, 4b, 4b, 4b, 4c, which are composed of a rectangular plate shape and are perpendicular to the other end faces of the four column members 4b, 4b, 4b, 4b The device comprises a flat plate (upper plate) 4c fixed to the lower surface 4c2 of the four corners (90°), a support jig 4d fixed to the upper surface 4c1 of the flat plate (upper plate) 4c, which supports the underside of the other end 2B of the rod-shaped member 2 by placing it on it from the shorter side, and roller parts 5a, 5a, 5a, 5a fixed to the four right-angle (90°) corners of the lower surface 4a2 of the flat plate 4a. While the other end 2B of the rod-shaped member 2 is supported by the support jig 4d by placing it on it from the shorter side, the roller parts 5a, 5a, 5a, 5a are not moved by the movement of the roller parts 5a, 5a, 5a, 5a, 5a, so that the movement of the roller parts 5a, 5a, 5a, 5a is restricted by a limiting mechanism (such as a movement prevention lock provided on the roller parts 5a, 5a, 5a, 5a).

[0020] The movable member 5 is provided below the roller portions 5a, 5a, 5a, 5a of the support member 4 and consists of a rail portion 5b having a pair of rails 5b1, 5b1 on which the roller portions 5a, 5a, 5a, 5a are configured to move.

[0021] The support jig 4d of the support member 4 is positioned so that the lower side of the other end 2B of the rod-shaped member 2 can be placed on it from the shorter side, and the movable member 5 is provided below the roller portions 5a, 5a, 5a, 5a of the support member 4 so that the support member 4 can move in a direction approximately 90° from the longitudinal direction of the rod-shaped member 2 by the roller portions 5a, 5a, 5a, 5a.

[0022] The frame 6 is composed of a pair of rectangular plate members 6a, 6a. The longitudinal end faces of the lower members 3Aa, 3Aa of the fixing member 3 are connected to one end 6A, 6A of the pair of plate members 6a, 6a, and the rail portion 5b of the moving member 5 is connected to the other end 6B, 6B of the pair of plate members 6a, 6a in a direction 90° from the longitudinal direction of the rod-shaped member 2 (in the figure, the direction of the arrow in the Y direction).

[0023] The support member 4 can be moved from the first position to the second position by lifting the other end 2B of the rod-shaped member 2, releasing the support of the support member 4 by the support jig 4d, and then moving the support member 4 along the rail portion 5b. The support member can be moved from the second position to the first position by lifting the other end 2B of the rod-shaped member 2, and then moving the support member 4 along the rail portion 5b to a position where the support jig 4d can be attached to and detached from the other end 2B of the rod-shaped member 2, and then placing the support jig 4d on top of the support member 4.

[0024] Next, Figures 5, 6, and 7 illustrate how to increase the number of coiled steel rods suspended from the cantilever beam as needed. Note that in Figures 5, 6, and 7, all components except for the fixing jig group 3B for the fixing member 3 and the support jig 4d for the support member 4 in Figure 1 have been omitted. With the support member 4 in the second position (cantilevered state), the inner circumference W1 side of the coiled steel rod W is inserted into the other end 2B of the rod-shaped member 2, thereby supporting the inner circumference X1 side of the coiled steel rod X with the rod-shaped member 2 and holding it in a suspended state in the diametrical direction X2. By repeating this process, multiple coiled steel rods W, W can be held in the suspended state.

[0025] Subsequently, the support member 4 is moved to the first position, and the other end 2B of the rod-shaped member 2 is supported by the support jig 4d of the support member 4. Then, in this state, the restraint band 10 is attached to the coiled steel rod X. Therefore, the work of attaching the restraint band 10 to multiple coiled steel rods X can be performed continuously, improving work efficiency. In addition, since the other end 2B of the rod-shaped member 2 is supported by the support jig 4d, the work can be performed safely. After the restraint band 10 is attached, the support provided by the support jig 4d is released, and the support member 4 is moved to the second position to retrieve the coiled steel rod X to which the restraint band 10 is attached.

[0026] Furthermore, instead of attaching the restraint band 10, the rust removal work on the coiled steel rod X can be performed efficiently and safely while the other end 2B of the rod-shaped member 2 is supported by the support jig 4d of the support member 4. In other words, the coiled steel rod straightening assist device according to this embodiment can straighten coiled steel rods efficiently and safely. [Industrial applicability]

[0027] The coiled steel bar straightening assist device according to this embodiment can suspend multiple coiled steel bars as needed, thereby enabling efficient and safe bundling of coiled steel bars. [Explanation of Symbols]
