Description

Technical Field

[0001] This utility model relates to the field of steel bar splicing technology in building construction, and in particular to a steel bar splicing positioning device for building construction. Background Technology

[0002] In building construction, steel bars serve as the "skeleton" of concrete structures, and the quality of their connections directly determines the load-bearing capacity, stability, and durability of the building structure. Steel bar splicing is a crucial process in steel reinforcement engineering, widely used in beam-column joint connections, precast component splicing, and the extension of extra-long steel bars.

[0003] The existing steel bar splicing and positioning device for building construction has a core structure consisting of a positioning frame, an alignment adjustment mechanism, a fastening device, and auxiliary support components. It clamps and fixes the steel bars, and uses the adjustment mechanism to achieve precise alignment of the axis or angle. It maintains stability during the connection operation, ensures the splicing accuracy, and can be disassembled and reused after completion, which can improve construction quality and efficiency.

[0004] While existing rebar butt positioning devices for building construction can butt rebars, the small diameter of the rebars makes butt jointing inconvenient and the accuracy cannot be guaranteed. This can lead to misalignment during subsequent welding. Furthermore, when buttling rebars of different heights, the device needs to be moved manually, which poses a safety hazard due to its weight. Therefore, a rebar butt positioning device for building construction is proposed to solve the above problems. Utility Model Content

Nut 1 (7) and Nut 27 (27) move on the threaded rod 6, which drives the V-arm 1 (8) and V-arm 2 (9) to move. A connecting rod 10 is rotatably connected to the bottom of V-arm 1 (8), and a connecting rod 10 is rotatably connected to the bottom of V-arm 2 (9). V-arm 1 (8) and V-arm 2 (9) are used to drive the connecting rod 10 to move up and down. A lifting assembly is fixedly connected to the bottom of the worktable 1.

[0034] Reference Figure 4 A lifting assembly is fixedly connected to the bottom of the workbench 1. The lifting assembly is used to move the workbench 1 to facilitate the connection of steel bars of different heights. The lifting assembly includes a support block 12, which is fixedly connected to the bottom of the workbench 1. There are two support blocks 12, which are evenly distributed on the bottom of the workbench 1. A lifting arm 13 is rotatably connected to the left side of the support block 12, and a lifting arm 2 14 is rotatably connected to the right side of the lifting arm 13. A drive shaft 15 is fixedly connected inside the lifting arm 2 14. A drive motor 17 is fixedly connected to the left end of the drive shaft 15. The drive shaft 15 is fixedly connected to the drive end of the drive motor 17. The drive motor 17 drives the drive shaft 15 to move, thereby driving the lifting arm 13 and the lifting arm 2 14 to move. A baffle 16 is fixedly connected to the left side of the drive motor 17. A base 18 is fixedly connected to the bottom of the baffle 16. Multiple evenly distributed positioning rings 19 are fixedly connected to the top of the base 18. A lifting arm 2 14 is installed between every two positioning rings 19.

[0035] Reference Figures 1-3The drive shaft 15 is rotatably connected inside the positioning ring 19. Multiple evenly distributed pads 20 are fixedly connected to the top of the base 18. A lifting rod 21 is fixedly connected to the top of each pad 20. A limit plate 22 is fixedly connected to the outer periphery of the lifting rod 21. Two positioning blocks 1 23 are fixedly connected to the top of the worktable 1. A guide 24 is fixedly connected to the top of each positioning block 1 23. The diameter of the round hole at the tail end of the guide 24 does not exceed 50mm of the diameter of the reinforcing bar. The guide 24 is used to ensure that the reinforcing bar moves in the correct direction. Multiple evenly distributed positioning blocks 25 are fixedly connected to the top of the worktable 1. A lower limit block 26 is fixedly connected to the top of each positioning block 25. The pads 20 are fixedly connected to the top of the worktable 1. A lifting rod 21 is connected, and the lifting rod 21 is made of alloy structural steel. A limit plate 22 is fixedly connected to the outer periphery of the lifting rod 21.

Two upper limit blocks 11 are fixedly connected to the bottom of the connecting rod 10. The upper limit blocks 11 are installed above the lower limit blocks 26. The diameter of the round hole where the upper limit blocks 11 and the lower limit blocks 26 fit is the same as the diameter of the steel bar. The closed round hole of the upper limit blocks 11 and the lower limit blocks 26 is coaxial with the circles of the guides 24 on both sides to ensure the rebar connection accuracy. The fixing rod 3 is fixedly connected to the top of the worktable 1.

[0036] Working principle: First, the worker places the reinforcing bars into the guides 24 on both sides of the workbench 1. Under the action of the guides 24, the ends of the two butt-jointed reinforcing bars are forcibly constrained, making their axes as consistent as possible, avoiding the eccentricity and tilting problems of manual positioning, and providing a prerequisite for welding or mechanical connection. The two reinforcing bars are then placed into the two lower limit blocks 26 through the guides 24 respectively. Then, the handwheel 5 is turned, which drives the nuts 7 and 27 on the threaded rod 6 to move, thereby driving the V-arms 8 and 9 to move, and then driving the connecting rod 10 to move downward. The upper limit block 11 is also moved downward by the connecting rod. 10. Move downwards and rotate handwheel 5 until upper limit block 11 and lower limit block 26 fit tightly together to fix the steel bar inside. Finally, perform subsequent welding or mechanical connection on the connected steel bars. When connecting steel bars of different heights, drive motor 17 needs to be started. Drive motor 17 drives transmission shaft 15 to rotate. Transmission shaft 15 drives lifting arm 2 14 to move. Lifting arm 2 14 drives lifting arm 1 13 to move. Lifting arm 1 13 drives support block 12 fixed at the bottom of workbench 1 to move, thereby moving workbench 1 up and down to facilitate connecting steel bars of different heights.
