Description

Technical Field

[0001] The utility model relates to the field of engineering construction, in particular to a portable steel bar adjusting device. Background Art

[0002] During pile foundation construction, first, holes are drilled at the positions where construction is required, then steel reinforcement cages are placed in the hole positions, and then grouting is carried out. Among them, when manufacturing the steel reinforcement cage, multiple straight bars and multiple hoop bars are directly bundled with steel wires to form the steel reinforcement cage. Among them, during the manufacturing process of the steel reinforcement cage, after bundling multiple hoop bars and multiple straight bars at one end with steel wires, the hoop bars are successively sleeved outside the multiple straight bars, and the corresponding hoop bars and straight bars are bundled with steel wires in turn. However, during actual bundling, some parts of the straight bars will be bent and deformed, and some positions of the hoop bars will also be bent and deformed, resulting in a relatively large direct distance between some straight bars and the hoop bars. The binding force of the steel wire is difficult to make the straight bars and the hoop bars contact, and the distance between the two is relatively large. In this way, the steel wire at this place is easily broken, and the steel wire on its side needs to bear a greater force, and the adjacent steel wire is also easily broken, which will affect the strength of the steel reinforcement cage and may cause the cage to fall apart when placed. Therefore, in order to ensure that the straight bars and the hoop bars can contact, generally, workers use hammers to knock the corresponding straight bars and hoop bars, or use steel bars to adjust the deformed parts of the straight bars or positions, so that the steel bars and the straight bars can contact, which is convenient for the steel wire to bundle the intersection of the two, thus ensuring the strength and firmness of the steel reinforcement cage. However, it is inconvenient for workers to adjust using hammers or steel bars, and it is also easy to have potential safety hazards. Or for other already installed steel bars, during the construction process or other situations, when a certain place is bent or deformed and needs to be reset, it is also manually adjusted using hammers or steel bars, which is inconvenient and there are also potential safety hazards. Or when the steel bars need to be bent or adjusted at certain positions after the steel bars are installed, since the steel bars are not convenient to disassemble and special equipment cannot be used to adjust, only steel bars, hammers, pliers, etc. can be used for adjustment, which is inconvenient and there are also potential safety hazards of injuring the operators. Therefore, how to solve the above technical problems is the direction that those skilled in the art need to strive for. Summary of the Invention

Specific implementation manner

[0027] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0028] Embodiment 1: Refer to Figures 1-4 As shown, a portable steel bar adjusting device includes a connecting plate 1, an adjusting member installed on the connecting plate 1, and two positioning members. The two positioning members are respectively arranged at both ends of the left side surface of the connecting plate 1, and the adjusting member is installed in the middle of the connecting plate 1;

[0029] The adjusting member includes a screw rod 2 and an adjusting positioning block 3. The middle of the screw rod 2 is screwed and connected to the middle of the connecting plate 1. The middle of the right side of the adjusting positioning block 3 is rotatably connected to the left end of the screw rod 2. The adjusting positioning block 3 is arranged between the two positioning members;

[0030] The left side surface of the adjusting positioning block 3 is provided with an adjusting positioning groove 4, and the right end of the screw rod 2 is provided with a grasping rod 5.

[0031] In this embodiment, when adjusting the steel bar 17, during use, first rotate the screw rod to move the adjusting positioning block towards the connecting plate, so that the left end of the adjusting positioning block is on the right side of the left end of the positioning member. Then position the two positioning members and the steel bar, and the adjusting positioning block is facing the position where the steel bar needs to be adjusted. Then the operator grabs the grasping rod and drives the screw rod to rotate. When the screw rod rotates, it drives the adjusting positioning block to move to the left. At this time, the adjusting positioning block moves towards the steel bar. When the adjusting positioning block moves and approaches the steel bar, the operator rotates the adjusting positioning block so that the adjusting positioning groove faces the steel bar. Then continue to rotate the screw rod so that the adjusting positioning groove catches the steel bar. Continue to rotate the screw rod, and the adjusting positioning block can be pushed to move to the left. Since the positioning member and the steel bar are positioned, the position of the left end of the positioning member will not move relative to the steel bar. When the adjusting positioning block moves to the left, the steel bar at this position deforms to the left, realizing the adjustment of the steel bar. After the adjustment is completed, the operator grabs the grasping rod and drives the screw rod to rotate in the reverse direction, so that the adjusting positioning block moves to the right and away from the steel bar. Then remove the positioning member from the steel bar. It is convenient and fast. The adjusting device can be made in different sizes to be suitable for use in different positions, which can effectively improve the convenience of steel bar adjustment, and will not hurt the staff, reducing the safety hazards during the operation process.

[0032] Refer to Figure 1 、 2As shown, the positioning member includes a positioning rod 6 and a positioning hook 7 arranged at the left end of the positioning rod 6, the right end of the positioning rod 6 is vertically connected to the connecting plate 1, the positioning hook 7 is bent toward the connecting plate 1, and a positioning groove 8 arranged toward the connecting plate 1 is formed between the positioning hook 7 and the positioning rod 6, the screw rod 2 and the positioning groove 8 are arranged on the same plane, and the bending directions of the positioning hooks 7 on both sides are opposite, one positioning hook is bent forward, and the other positioning hook is bent backward.

[0033] In this embodiment, the positioning member adopts a positioning rod and a positioning hook, and the positioning groove of the positioning hook is directly hooked on the steel bar, so that if the adjustment device wants to move to the right, it will be limited by the positioning hook and the steel bar. Then, when the screw rotates to drive the adjustment positioning block to move to the left, the steel bar and the positioning hook give the connecting plate a pulling force, so that the connecting plate cannot move to the right away from the steel bar. In this way, when the adjustment positioning block moves to the left, the steel bar between the two positioning hooks can be pushed to deform to the left by the steel bar itself, thereby achieving the adjustment of the steel bar. At the same time, the adjustment positioning groove clamps the steel bar, so that during the deformation of the steel bar, the adjustment positioning block will not be separated from the steel bar, thereby ensuring the stability and safety of the steel bar adjustment process. At the same time, since the bending directions of the positioning hooks on both sides are opposite, after the positioning hooks on both sides are connected to the rigidity, the problem of the positioning device rotating relative to the steel bar can be prevented as much as possible (of course, the adjustment device can still rotate relative to the steel bar, but the adjustment device will be more balanced), thereby ensuring the stability and safety of the rigidity adjustment.

[0034] In one embodiment, a screw hole is provided in the middle of the connecting plate, and the middle of the screw rod is screwed to the screw hole. In this structure, the connecting plate needs to be solid, which is heavy. If the operator operates for a long time, the labor intensity will be higher, but the strength is stronger.

[0035] See also Figures 1-3 As shown, in order to reduce the weight of the adjustment device as a whole and reduce the labor intensity of the operator's frequent operations, in this embodiment, the connecting plate 1 is a hollow structure, a through hole 9 is provided in the middle of the connecting plate 1, and the two ends of the through hole 9 are respectively connected to the left side and the right side of the connecting plate 1;

[0036] A nut 10 is respectively installed on the left side and the right side of the connecting plate 1, and the nut 10 is coaxially arranged with the through hole 9. The middle part of the screw rod 2 is inserted into the through hole 9, and the two sides of the middle part of the screw rod 2 are respectively screwed together with two nuts 10. The diameter of the through hole is slightly larger than the inner diameter of the screw hole, so that when the screw rod rotates, the screw rod will not contact the inner wall of the through hole, preventing the external thread of the screw rod from being interfered by the through hole.

[0037] That is, in this embodiment, a square steel pipe is directly used as the connecting plate, and nuts are welded on both sides, so that the screw rod can rotate to adjust the position of the left end of the screw rod, that is, to adjust the position of the adjusting positioning block relative to the connecting plate, realizing the fast, stable and safe adjustment of the steel bar.

[0038] See Figure 1 、 2 As shown, the left side of the screw rod 2 is arranged on the left side of the connecting plate 1, the right end of the screw rod 2 and the gripping rod 5 are arranged on the right side of the connecting plate 1, and the gripping rod 5 is arranged perpendicular to the screw rod 2. The arrangement of the gripping rod facilitates the operator to drive the screw rod to rotate and facilitates the application of a circumferential rotational force to the screw rod.

[0039] Among them, the cross-section of the adjusting positioning groove is a V-shaped structure or an arc-shaped structure. In this embodiment, the adjusting positioning groove adopts a V-shaped structure, so that the steel bar can be clamped by the adjusting positioning groove, preventing the steel bar from disengaging from the adjusting positioning block when the adjusting positioning block pushes the steel bar to deform. Even if the adjusting device rotates relative to the steel bar, the steel bar will not come out of the adjusting positioning groove, ensuring safety during use.

[0040] At the same time, since the length of the steel bar is longer than the length of the adjusting positioning block, in order to make the position of the steel bar to be adjusted fit into the adjusting positioning groove, both ends of the adjusting positioning groove penetrate through the opposite end faces of the adjusting positioning block.

[0041] See Figure 1 、 2 As shown in 、4, a connecting pipe 11 is provided at the exact center of the right side surface of the adjusting positioning block 3. A connecting hole is provided at the right end of the connecting pipe 11, and a connecting piece is provided at the left end of the screw rod 2 and is rotatably connected to the connecting hole.

[0042] The connecting hole includes a left hole 12 and a right hole 13 arranged coaxially. The left end of the left hole 12 and the right end of the right hole 13 are respectively communicated with the left end surface and the right end surface of the connecting pipe 11. The right end of the left hole is communicated with the left end of the right hole 13. The diameter of the left hole 12 is larger than the diameter of the right hole 13;

[0043] An annular boss 14 is provided on the outer surface of the left side of the connecting pipe 11. The left side surface of the annular boss 14 abuts against the right side surface of the adjusting positioning block 3, and the annular boss 14 is connected to the adjusting positioning block 3 by bolts.

[0044] The connecting member includes a coupling shaft 15 and a convex ring 16 arranged coaxially. The outer diameter of the convex ring 16 is greater than that of the coupling shaft 15. The right end of the coupling shaft 15 is coaxially connected to the left end of the screw rod 2. The middle part of the right end of the convex ring 16 is connected to the left end of the coupling shaft 15. The convex ring 16 is arranged in the left hole 12. The left end of the coupling shaft 15 passes through the right hole 13 and is connected to the convex ring 16 in the left hole 12. The outer diameter of the convex ring 16 is greater than the diameter of the right hole 13, and the outer diameter of the coupling shaft 15 is smaller than the diameter of the right hole 13.

[0045] In this embodiment, when the left end of the screw rod is connected to the adjustment positioning block, first pass the right end of the coupling shaft through the left end of the connecting pipe and through the connecting hole, so that the convex ring is in the left hole, and the right end of the coupling shaft passes through the right hole and is at the right end of the connecting pipe. Then weld the left end of the screw rod and the right end of the coupling shaft, and then screw the annular boss to the right side of the adjustment positioning block through bolts. Of course, the outer diameter of the coupling shaft can also be greater than or equal to the outer diameter of the screw rod. In this way, after the coupling shaft and the screw rod are welded first (the grab bar is not installed yet), then the right end of the screw rod passes through the connecting hole from the left side of the connecting pipe, so that the convex ring is in the left hole, and then the annular boss and the adjustment positioning block are screwed and fixed. Then screw the screw rod and the connecting plate, and finally install the grab bar and the screw rod. The grab bar can be welded or screwed to the screw rod.
