Detailed implementation manners

[0026] Embodiments will be described in detail below, and examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The implementation manners described in the following embodiments do not represent all implementation manners consistent with the present application. They are merely examples of systems and methods consistent with some aspects of the present application detailed in the claims.

[0027] When manually embedding the jointed steel bars, it is difficult to precisely control the position and angle of the steel bars, which may cause the steel bars to be skewed, the exposed lengths to be inconsistent, the spacing to be uneven, and the linear shape to be non-straight. When the steel bars are skewed, the skewed steel bars need to be disassembled, corrected, and then fixed through a fixing device. The correction process is cumbersome, and since the steel bars are rigid, manual correction is difficult, making the correction process time-consuming and resulting in low construction efficiency.

[0028] To solve the problem of inconvenient correction of jointed steel bars, an embodiment of the present application provides a jointed steel bar correction device. Refer to Figure 1-2 , the device includes: a fixing component 1 and a correction component 2.

[0029] The fixing component 1 includes a telescopic sleeve 12. The telescopic sleeve 12 can be a circular tube or a rectangular tube, and the structure of the telescopic sleeve 12 is not limited in the embodiments of the present application.

[0030] The correction component 2 includes a housing 21, a gear 22, a rack 24, a locking pin 25, a handle 27, and a positioning ring 29. In some embodiments, the housing 21 can be a rectangular housing, and the rack 24 slides through the housing 21. The gear 22 is disposed inside the housing 21, and the gear 22 meshes with the rack 24. The handle 27 is rotatably connected to the side surface of the housing 21, and one end of the handle 27 is fixedly connected to the gear 22. The handle 27 can be a slender round rod, and the handle 27 is perpendicular to the side surface of the housing 21 parallel to the rack 24. Bearings can be provided on the side surface of the housing 21 to enable the handle 27 to be rotatably connected to the housing 21 through the bearings. A bend can be provided at the end of the handle 27 outside the housing 21 to facilitate grasping the handle 27. Rotating the handle 27 can drive the gear 22 to rotate, and then drive the rack 24 to move.

[0031] One end of the rack 24 is detachably connected to one end of the positioning ring 29, and the other end of the positioning ring 29 is sleeved on the jointed steel bar. It can be understood that both the positioning ring 29 and the rack 24 are perpendicular to the jointed steel bar. In some embodiments, the number of the positioning rings 29 can be two to make the sleeving of the positioning ring 29 on the jointed steel bar more stable. When the rack 24 moves, it can drive the positioning ring 29 to move.

[0032] The locking pin 25 penetrates through the housing 21 from the outside of the housing 21 and limits the rack 24 located inside the housing 21. The locking pin 25 can be arranged on the top surface of the housing 21, penetrate downward through the housing 21 from the top surface of the housing 21, and the end of the locking pin 25 is clamped with the rack 24 to limit the rack 24. Since the corrected joint steel bar has resilience, it will drive the positioning ring 29 and the rack 24 to move back. By arranging the locking pin 25 to limit the rack 24, the probability of correction failure caused by the backward movement can be reduced.

[0033] One end of the telescopic sleeve 12 is detachably connected to the housing 21, and the other end of the telescopic sleeve 12 is fixed to the short-side wall formwork 3. For example, the top end and the bottom end of the telescopic sleeve 12 can be fixed to the bottom surface of the housing 21 and the top surface of the short-side wall formwork 3 respectively by bolt connection. When it is necessary to correct the skewed joint steel bar, rotate the handle 27 to drive the gear 22 to rotate, and then drive the rack 24 and the positioning ring 29 to move, so as to straighten the skewed joint steel bar. At this time, the locking pin 25 is clamped with the rack 24 to limit the rack 24. The correction device provided by the above embodiment can correct the skewed joint steel bar without disassembling the joint steel bar from the fixing device, which is convenient for correction, the correction process is simple, and the construction efficiency can be improved.

[0034] Refer to again Figure 2 , in some embodiments, the telescopic sleeve 12 includes a first sleeve 121, a second sleeve 122 and a plug pin 124. The second sleeve 122 is sleeved outside the first sleeve 121. A positioning hole is arranged on the side surface of the second sleeve 122, and a plurality of adjusting holes 123 are arranged on the side surface of the first sleeve 121. The plug pin 124 is inserted into the positioning hole and one of the adjusting holes 123. By inserting the plug pin 124 into different adjusting holes 123, the height of the second sleeve 122 relative to the first sleeve 121 can be adjusted to perform telescopic adjustment on the telescopic sleeve 12. The first sleeve 121 and the second sleeve 122 can be arranged as rectangular tubes. Compared with circular tubes, when performing telescopic adjustment, the external second sleeve 122 can be directly limited and will not rotate, which is convenient for the plug pin 124 to be inserted into the adjusting hole 123.

[0035] The interior of the second sleeve 122 is provided with a first sliding groove 126. The top end of the first sleeve 121 is provided with a limiting plate 125, and the limiting plate 125 is slidably connected to the first sliding groove 126. The first sliding groove 126 is a groove provided on two side walls parallel to each other inside the first sleeve 121. The length of the first sliding groove 126 is less than the length of the second sleeve 122, so that a step can be formed between the first sliding groove 126 and the inner side wall of the second sleeve 122 inside the second sleeve 122. Both ends of the limiting plate 125 extend beyond the outer side surface of the first sleeve 121 and enter the first sliding groove 126. When the second sleeve 122 slides to the end of the first sleeve 121, the limiting plate 125 is limited by the step formed by the first sliding groove 126 and the inner side wall of the second sleeve 122, so that the second sleeve 122 will not be disengaged from the top of the first sleeve 121.

[0036] The top end of the second sleeve 122 is provided with a connecting plate 127, and the connecting plate 127 and the top end of the second sleeve 122 can be connected by welding. The telescopic sleeve 12 is detachably connected to the bottom surface of the housing 21 through the connecting plate 127. Installation holes can be provided on the connecting plate 127, and the connecting plate 127 and the bottom surface of the housing 21 can be fixed by bolts.

[0037] In some embodiments, the correction assembly 2 further includes a connecting seat 28. The connecting seat 28 can be a rectangular block. One side of the connecting seat 28 is detachably connected to one end of the rack 24, and the other side of the connecting seat 28 is detachably connected to the end of the positioning ring 29 away from the butt joint steel bar. The positioning ring 29 includes a positioning circular ring and a connecting rod. The positioning circular ring is fixedly connected to one end of the connecting rod. Connecting threads can be provided at the other end of the connecting rod, and the connecting rod can be fixed to the connecting seat 28 by threads. A fixing groove 281 can be provided on the side of the connecting seat 28 close to the rack 24, so that the rack 24 is detachably connected to the connecting seat 28 through the fixing groove 281, such as bolt connection.

[0038] See again Figure 1 , the fixing assembly 1 further includes a support rod 15. The support rod 15 can be a circular rod. One end of the support rod 15 is slidably connected to the side surface of the second sleeve 122. The other end of the support rod 15 is hinged to the connecting seat 28, and the support rod 15 is inclined relative to the second sleeve 122. A rotating shaft 151 can be provided at one end of the support rod 15 close to the connecting seat 28, and a hinge block can be provided on the bottom surface of the connecting seat 28. The rotating shaft 151 is inserted into the hinge block, so that the support rod 15 is hinged to the bottom surface of the connecting seat 28 through the rotating shaft 151 and the hinge block. In some embodiments, the hinge block can also be provided on the side surface of the connecting seat 28, so that the support rod 15 is hinged to the side surface of the connecting seat 28. Since the rack 24 is relatively long, by providing the support rod 15, the rack 24 can be supported, so as to reduce the probability of deflection deformation of the rack 24.

[0039] It can be understood that the support rod 15, the rack 24, and the second sleeve 122 form a triangular structure. Since one end of the support rod 15 is slidably connected to the side surface of the second sleeve 122, the support rod 15 can slide relative to the second sleeve 122, and the included angle between the support rod 15 and the second sleeve 122 changes, which can drive the connecting seat 28 to move horizontally. At the same time, the rack 24 moves horizontally driven by the gear 22.

[0040] A slider 152 is provided at one end of the support rod 15. The slider 152 is hinged to the end of the support rod 15. A second chute 128 is provided on the side surface of the second sleeve 122. The slider 152 can be a rectangular block, and the second chute 128 can be a U-shaped groove. The slider 152 is slidably connected to the second chute 128 so that when the support rod 15 slides along the second chute 128, the included angle between the support rod 15 and the second sleeve 122 can be changed, thereby driving the connecting seat 28 to move.

[0041] In some embodiments, the correction assembly 2 further includes a support plate 23. The support plate 23 is detachably connected to the bottom surface of the rack 24. One end of the rack 24 close to the connecting seat 28 is detachably connected to the fixing groove 281 through the support plate 23. In practical applications, since the rack 24 is made of wear-resistant metal material and has a large hardness and is not easy to be drilled and processed, the rack 24 can be fixed on the top surface of the support plate 23, and a connection hole is provided at the end of the support plate 23 to connect the support plate 23 with the fixing groove 281. See Figure 3 A baffle 26 is provided at one end of the support plate 23 away from the connecting seat 28. The baffle 26 is fixedly connected to the support plate 23, such as by welding. The baffle 26 is used to limit the rack 24.

[0042] See Figure 4 See, the locking pin 25 includes a screw rod 252 and a clamping block 253. The clamping block 253 is provided at one end of the screw rod 252. A limiting sleeve 211 is provided at the top of the housing 21. Threads are provided on the outer side of the screw rod 252, and threads are also provided on the inner side of the limiting sleeve 211. The screw rod 252 is threadedly connected to the limiting sleeve 211, and the clamping block 253 is clamped with the rack 24. When it is necessary to limit the rack 24, the screw rod 252 is rotated so that the clamping block 253 is clamped with the teeth on the rack 24, and the rack 24 can be limited.

[0043] As can be seen from the above technical solutions, an embodiment of the present application provides a stub bar straightening device, which includes a fixing component 1 and a straightening component 2. The fixing component 1 includes a telescopic sleeve 12, and the straightening component 2 includes a housing 21, a gear 22, a rack 24, a locking pin 25, a handle 27 and a positioning ring 29. The rack 24 slides through the housing 21, and the gear 22 is arranged inside the housing 21 and meshes with the rack 24; the handle 27 is rotatably connected to the side surface of the housing 21, and one end is connected to the gear 22. One end of the rack 24 is detachably connected to one end of the positioning ring 29, and the other end of the positioning ring 29 is sleeved on the stub bar; the locking pin 25 penetrates through the housing 21 from the outside of the housing 21 and limits the rack 24 located inside the housing 21. One end of the telescopic sleeve 12 is detachably connected to the housing 21, and the other end is fixed on the low-side wall formwork 3. When it is necessary to straighten the skewed stub bar, rotate the handle 27 to drive the gear 22 to rotate, and then drive the rack 24 and the positioning ring 29 to move, so as to straighten the skewed stub bar. At this time, engage the locking pin 25 with the rack 24 to limit the rack 24. Through the above straightening device, it is not necessary to disassemble the stub bar from the fixing device to straighten the skewed stub bar. The straightening is convenient, the straightening process is simple, and the construction efficiency can be improved.
