Description

Technical Field

[0001] The invention relates to a preparation tool for a ring-shaped steel bar structure. Background Art

[0002] Annular reinforcement ribs are widely used in barrel-shaped containers. When casting the annular reinforcement ribs, an annular steel bar structure needs to be placed in the mold in advance. The annular steel bar structure is formed by bending straight steel bars and fixing multiple circles of straight steel bars to each other after bending. In the prior art, in the process of bending straight steel bars and fixing them to each other, operators often rely on experience to fix them, resulting in poor concentricity of multiple circles of annular steel bars after they are fixed to each other; and at different positions where the annular steel bars are fixed, the distances between multiple circles of annular steel bars are often different, resulting in poor fixing effect, large shape and size errors after fixing, and very low preparation efficiency of the annular steel bar structure. Summary of the invention

DETAILED DESCRIPTION

[0024] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0025] The annular steel bar structure comprises at least two annular steel bars which extend coaxially, are spaced apart from each other and are fixed to each other.

[0026] See also Figure 1 As shown, the above-mentioned preparation tool for annular steel bar structure includes a connecting component that can rotate around the axial direction of the first axis 1, an annular bearing component fixedly mounted on the connecting component, a limiting component fixedly mounted on the annular bearing component for limiting the position of the annular steel bars, and a fixing component mounted on the annular bearing component for fixedly connecting at least two annular steel bars.

[0027] The first axis 1 is arranged on the ground and can rotate around its own axis centerline, and the axis centerline of the first axis 1 extends in the vertical direction. There are multiple fixing components, and the multiple fixing components are arranged on the annular bearing component in a circle at even intervals in sequence; there are multiple limiting components, and the multiple limiting components are arranged on the annular bearing component in a circle at even intervals in sequence. The annular bearing component extends coaxially with the first axis 1.

[0028] In the obtained annular steel bar structure, a plurality of fixing components are evenly arranged at intervals along the circumferential direction. The annular steel bar structure is used to be cast in a mold to form annular reinforcing ribs.

[0029] See also Figure 2 As shown, the fixing assembly comprises a plate body 2 extending in the radial direction of the annular steel bar, a plate body 2 provided on the inner side of the plate body 2 in the radial direction (the inner side is the Figure 2 The first groove 3 (on the left side) and at least two grooves are opened on the outer side of the plate body 2 along the radial direction (the outer side here is Figure 2 The first groove 3 opens to the left, and the second groove 4 opens to the right.

[0030] In this embodiment, the length extension direction of the first groove 3 is parallel to the length extension direction of the second groove 4. The first groove 3 includes a first notch 31 for allowing the inner annular reinforcement to enter in the radial direction, and a first arc-shaped groove bottom 32 for limiting the entered annular reinforcement; the second groove 4 includes a second notch 41 for allowing the outer annular reinforcement to enter in the radial direction, and a second arc-shaped groove bottom 42 for limiting the entered annular reinforcement. The first notch 31 and the second notch 41 are both composed of two groove edges parallel to each other, the first notch 31 and the second notch 41 are parallel to each other, the first arc-shaped groove bottom 32 and the second arc-shaped groove bottom 42 are both arc-shaped, and the inner diameters of the first arc-shaped groove bottom 32 and the second arc-shaped groove bottom 42 are the same as the outer diameters of the corresponding cross-sections of the entered annular reinforcement, so as to limit the entered annular reinforcement in cooperation.

[0031] In this embodiment, see Figure 2 As shown, a first groove 3 is provided on the left side of the plate body 2, and three second grooves 4 are provided on the right side of the plate body 2. The length extension directions of the three second grooves 4 are parallel to each other and to the length extension direction of the first groove 3. The first groove 3 and the second groove 4 are used to coaxially fix annular steel bars of different diameters. By using a fixing assembly of the same size to fix multiple circles of annular steel bars at different positions, not only is the fixing effect good, but also the coaxial extension of each circle of annular steel bars after fixation can be ensured.

[0032] In order to further improve the fixing effect of the fixing assembly on the annular steel bar, the annular steel bar inserted into the first groove 3 or the second groove 4 passes through the two side surfaces of the plate body 2 (see Figure 2 As shown, that is, the two side surfaces of the plate body 2 in the front and rear directions are welded on the plate body 2.

[0033] The above-mentioned fixing assembly also includes a first inclined surface 5 which is arranged at the top end of the plate body 2 and extends gradually upward from the inside to the outside along the radial direction, a second inclined surface 6 which is arranged at the bottom end of the plate body 2 and extends gradually downward from the inside to the outside along the radial direction, a horizontal bottom surface 7 which is arranged at the bottom end of the plate body 2 and connected to the lowest point of the second inclined surface 6, a horizontal top surface 8 which is arranged at the top end of the plate body 2 and connected to the highest point of the first inclined surface 5, and a limit plate 9 which protrudes upward on the horizontal top surface 8.

[0034] See also Figure 2 As shown, the first inclined surface 5 is located on the left side of the horizontal top surface 8, and the second inclined surface 6 is located on the left side of the horizontal bottom surface 7. The first inclined surface 5 extends obliquely from the lower left to the upper right, and the second inclined surface 6 extends obliquely from the upper left to the lower right. The second inclined surface 6 and the horizontal bottom surface 7 are used to cooperate with each other to contact the annular bearing component located below the fixing component, so that the length extension direction of the first groove 3 and the second groove 4 are parallel to the radial direction, that is, the horizontal bottom surface 7 is attached to the annular bearing component in the horizontal direction.

[0035] By arranging the limiting plate 9 on the horizontal top surface 8, when the fixing assembly fixes multiple circles of annular steel bars, the limiting plate 9 will not affect the placement of the fixing assembly because it contacts the annular bearing assembly through the second inclined surface 6 and the horizontal bottom surface 7. After the annular steel bar structure is made, it is turned upside down so that the limiting plate 9 is located at the bottom. After the annular steel bar structure is placed in the mold to be cast, the limiting plate 9 at the bottom plays a role in limiting the annular steel bar structure.

[0036] See also Figure 3 As shown, the above-mentioned limiting assembly includes two limiting columns 10 arranged at intervals in the radial direction and used to cooperate with each other to clamp the outer annular steel bar. In this embodiment, the two limiting columns 10 are parallel to each other and parallel to the first axis 1. It is used to limit the annular steel bar inserted into the second groove 4.

[0037] See also Figure 1 As shown, the connection assembly includes a cross connection frame 11 coaxially connected to the first shaft 1, and a roller (not shown in the figure) arranged at the bottom of the cross connection frame 11. In this embodiment, the cross connection frame 11 extends in the horizontal direction, and the roller at the bottom is used to assist the rotation when the cross connection frame 11 rotates around the axis of the first shaft 1, so that the rotation is freer and faster, and the preparation efficiency of the annular steel bar structure is improved.

[0038] See also Figure 1 As shown, the annular bearing assembly comprises an annular body 12 externally connected to the cross connecting frame 11, and a radial protrusion 13 convex inwardly in the radial direction and arranged on the inner surface of the annular body 12. In this embodiment, the radial protrusion 13 extends in the horizontal direction.

[0039] See also Figure 2 As shown, the left bottom of the fixing assembly abuts against the radial protrusion 13, and the right bottom of the fixing assembly abuts against the annular body 12. Since the lower surface of the fixing assembly includes the second inclined surface 6, in order to cooperate with the abutment against the second inclined surface 6, the annular bearing assembly also includes a bearing column 14 fixed on the radial protrusion 13, and the bearing column 14 is flatly arranged on the radial protrusion 13 and is perpendicular to the fixing assembly. That is, the second inclined surface 6 abuts against the bearing column 14, and the horizontal bottom surface 7 abuts against the annular body 12.

[0040] See also Figure 1 , Figure 3 As shown, the above-mentioned limiting column 10 is fixed on the annular body 12. The heights of the two limiting columns 10 can be the same or different, and both are not lower than the highest second groove 4. In other words, no matter which second groove 4 is used to fix the annular steel bar, it can be limited by the limiting column 10.

[0041] A circular steel bar structure is prepared by the preparation tool. The operator does not need to move during the preparation process. He only needs to rotate the circular bearing assembly to quickly and efficiently complete the preparation of the outer and inner ring steel bars. The multiple rings of ring steel bars in the prepared circular steel bar structure have good fixing effect and extend coaxially.

[0042] The working process of this embodiment is described in detail below:

[0043] Fix the circular reinforcement connecting the outer ring:

[0044] Insert the straight steel bar into the limit column 10 and into the second groove 4 of the corresponding height on the fixing component, weld the steel bar to the fixing component, and then rotate the annular body 12; repeat this step until the straight steel bar penetrates all the limit columns 10 and all the second grooves 4 of the same height to form an outer ring of annular steel bars;

[0045] Fix and connect two to three circles of circular steel bars one by one as needed;

[0046] To fix the circular reinforcement connecting the inner ring:

[0047] Insert the straight steel bar into the first groove 3 on the fixing assembly, weld the steel bar to the fixing assembly, and then rotate the annular body 12; repeat this step until the straight steel bar is inserted into all the first grooves 3 to form an inner ring of annular steel bars.

[0048] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
