Description

Technical Field

[0001] This utility model belongs to the field of rebar splicing technology, and in particular relates to a rebar splicing device for building engineering. Background Technology

[0002] Rebar splicing refers to the process of connecting multiple rebars to a length that meets the requirements of a project in construction engineering. Because the actual length of a single rebar is limited, it cannot directly meet the construction requirements of large building structures. Therefore, rebar splicing has become a key link to ensure that the rebar system can work effectively together. From a technical point of view, rebar splicing must ensure that the connection part has sufficient strength to stably transmit various stresses such as tension and compression, thereby maintaining the stability and safety of the building structure under different load conditions.

[0003] During the splicing of reinforcing bars, the difference in diameter between the receiving and splicing bars makes it difficult to align their axes during clamping and fixing. This makes it challenging to ensure that the two bars to be spliced ​​are precisely on the same axis. Misalignment of the reinforcing bar axes can lead to eccentric stress at the splice joint under heavy loads, significantly reducing the structure's load-bearing capacity and potentially causing safety accidents. Therefore, a reinforcing bar splicing device for building engineering is needed. This device employs an adjustable clamping radius structure to accurately accommodate reinforcing bars of different diameters, ensuring accurate axis alignment during splicing and guaranteeing the stability of the spliced ​​bars.

[0022] In the following description, embodiments of the steel bar splicing device for building engineering according to the present invention will be described with reference to the accompanying drawings.

[0023] Figures 1-4This invention illustrates a rebar splicing device for building construction according to an embodiment of the present invention. It includes a support 1: clamp seats 2 are provided at both the top and bottom of the support 1 surface; the support 1 is slidably connected to the upper clamp seat 2, and the support 1 is fixedly connected to the lower clamp seat 2; a clamping claw 3 is fixedly connected to the right side of the clamp seat 2; a clamping assembly 4 is provided at the front side of the clamp seat 2; the clamping assembly 4 includes a threaded sleeve 41 fixedly connected to the front side of the clamp seat 2; a threaded abutment 42 is threadedly connected to the inner cavity of the threaded sleeve 41; a slidable clamping block 43 is provided in the inner cavity of the clamping claw 3; and the front of the clamping block 43... Limiting sliders 9 are fixedly connected to both the side and rear sides. Limiting grooves 10 are provided on both the front and rear sides of the inner cavity of the gripper 3. The limiting sliders 9 are slidably connected to the inner cavity of the limiting grooves 10. Through the cooperation of the limiting sliders 9 and the limiting grooves 10, the clamping block 43 is limited, so that the clamping block 43 can be stably placed in the inner cavity of the gripper 3, thereby improving the stability of the steel bar clamping. The surface of the clamping block 43 is provided with multiple anti-slip ridges 11. The anti-slip ridges 11 are adapted to the inclination angle of the surface texture of the threaded steel bar. A threaded post 44 is fixedly connected to the right end of the clamping block 43. A rotatable threaded sleeve 45 is provided through the side, and the threaded sleeve 45 is threaded to the surface of the threaded post 44. An indicator arrow 5 is fixedly connected to the rear side of the top of the clamping block 43. A scale mark 6 matching the indicator arrow 5 is provided on the rear side of the top of the clamping jaw 3. A gear box 7 is fixedly connected to the top of the bracket 1. A lifting assembly 8 is provided in the inner cavity of the gear box 7. The lifting assembly 8 includes a lifting screw 81 rotatably connected to the bottom of the gear box 7. The top of the lifting screw 81 extends through the inner cavity of the gear box 7 and is fixedly connected to a force-bearing bevel gear 82. An operating lever 83 is rotatably connected to the left side of the gear box 7. The right end of the operating lever 83 passes through the inner cavity of the gear box 7 and is fixedly connected to the driving vertical bevel gear 84. The bottom end of the lifting screw 81 passes through the inner cavity of the upper clamp seat 2 and is threadedly connected to the clamp seat 2. The operating lever 83 and the driving vertical bevel gear 84 mesh with each other. Through the setting of the lifting assembly 8, the cooperation between the operating lever 83 and the driving vertical bevel gear 84 drives the force bevel gear 82 to rotate. At the same time, under the cooperation between the force bevel gear 82 and the lifting screw 81, the clamp seat 2 is raised and lowered, so that the steel bar located above can be vertically connected.

[0024] Working Principle: When using this invention, the user places the bottom clamp 3 onto the surface of the receiving rebar, then rotates the threaded abutment 42, causing the right end of the threaded abutment 42 to push to the right and press against the surface of the receiving rebar. At this time, the receiving rebar is clamped and fixed, and the bracket 1 remains upright under the support of the receiving rebar. Then, the user inserts the connecting rebar into the inner cavity of the upper clamp 3. According to the diameter difference between the connecting rebar and the receiving rebar, the user adjusts the position of the clamping block 43. During adjustment, the user rotates the threaded sleeve 45. During the rotation, the threaded sleeve 45 pushes the clamping block 43 forward through the cooperation of its inner wall thread and the surface thread of the threaded column 44, causing the clamping block 43 to slide in the inner cavity of the clamp 3 and adjust the finger. Arrow 5 moves to different positions on scale mark 6. According to the reading on scale mark 6, clamp block 43 is adjusted into place. Then, the threaded abutment 42 located above is rotated. Through the cooperation of threaded abutment 42 and clamp block 43, the splicing rebar is clamped and fixed. At this time, the splicing rebar and the receiving rebar are on the same axis. The pressure welding box is placed between the receiving rebar and the splicing rebar, and welding is performed. Finally, the user rotates the operating lever 83. During the rotation of the operating lever 83, the meshing transmission of the driving vertical bevel gear 84 and the force bevel gear 82 drives the lifting screw 81 to rotate. During the rotation of the lifting screw 81, the clamp seat 2 located above moves downward, so that the splicing rebar can be connected downward.

[0025] In summary, this rebar splicing device for construction projects uses the gripper 3 and clamping component 4 to clamp and fix two rebars of different diameters. Then, the two rebars are welded together by a welding machine. During welding, the clamp seat 2, gear box 7 and lifting component 8 work together to press down and connect the upper rebar, thus achieving accurate axial alignment and applicability to splicing rebars of different diameters.
