Description

Technical Field

[0001] The utility model provides a steel bar connecting component for highway bridge construction, belonging to the technical field of steel bar connection. Background Art

[0002] Highway bridges are key traffic infrastructure that span rivers, valleys, roads, and other obstacles. Their design and construction embody the perfect combination of engineering technology and aesthetics. Bridges not only bear the heavy responsibility of carrying vehicles and pedestrians safely, but also often become iconic buildings in the region. Highway bridges have diverse structures, including beam bridges, arch bridges, suspension bridges, cable-stayed bridges, etc. Each type is selected according to its spanning ability, construction conditions, and landscape requirements. The construction of bridges needs to consider natural factors such as geology, hydrology, and climate, as well as social and economic factors such as traffic flow and service life, to ensure its structural safety, durability, and ability to meet the growing transportation needs.

[0003] Publication No.: CN217870022U; discloses a steel bar connecting component for highway bridge construction, including a base partition. U-shaped sleeves are connected to the left and right sides of the base partition. Corresponding movable sleeve plates are movably installed on the left and right sides of the base partition through U-shaped sleeves. Threaded drive rods are arranged on both sides of the upper surface of the T-shaped sleeve frame. Reinforcing bar sleeves are correspondingly arranged on the upper surfaces of the threaded drive rods. Compression bolts are used to clamp steel bars of different sizes.

[0004] The above patent can fix the steel bars on both sides through the cooperation of compression bolts and reinforcing bar sleeves, and can pull the steel bars on both sides by rotating the crank to facilitate welding. However, in actual use, after the steel bars on both sides are connected, the compression bolts need to be loosened, and then the device needs to be moved all the way to the end of one side of the steel bar before it can be taken out, which is rather troublesome. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that the existing device is inconvenient to remove after the steel bars are connected.

[0006] In order to solve the above problems, the technical solution proposed by the utility model is: a steel bar connecting component for highway bridge construction, including a bidirectional lead screw; the bidirectional lead screw is rotatably arranged in a frame body. Lower moving blocks that are threadedly connected to the bidirectional lead screw are respectively arranged on both sides inside the frame body. The lower moving blocks are hinged to upper moving blocks. Corresponding semi-circular through grooves are arranged in the middle of the upper end of the lower moving block and the middle of the lower end of the upper moving block. An adjusting bolt is threadedly connected to the middle of the upper moving block. The lower moving blocks and the upper moving blocks are fixed through fixing bolts.

[0007] As an improvement, both ends of the bidirectional lead screw pass through the frame body through bearings, and cranks are respectively arranged at both ends;

[0008] As an improvement, one side of the lower moving block is connected to the upper moving block through a hinge;

[0009] As an improvement, a first threaded hole corresponding to the bidirectional lead screw is provided in the middle and lower part of the lower moving block, and a second threaded hole corresponding to the fixing bolt is provided on the side of the upper part away from the hinge.

[0010] As an improvement, a third threaded hole corresponding to the adjusting bolt is provided in the middle of the upper moving block, and a second threaded hole corresponding to the fixing bolt is provided on the side away from the hinge.

[0011] Advantages of the utility model:

[0012] By arranging lower moving blocks connected by threads on both sides of the bidirectional lead screw, arranging an upper moving block hinged on the lower moving block and fixing it with fixing bolts, and arranging an adjusting bolt on the upper moving block, when the device is in use, after rotating the upper moving block to place the steel bar into the semi-circular through groove of the lower moving block, then fixing the lower moving block and the upper moving block with the fixing bolts, the steel bar will be in the semi-circular through grooves of the lower moving block and the upper moving block. Then, the adjusting bolt can be used to fix the steel bar, and then rotating the bidirectional lead screw can make the steel bars on both sides approach each other, thus facilitating connection. When the connection is completed, loosening the adjusting bolt and removing the fixing bolt can rotate the upper moving block, thus facilitating the removal of the device.

[0017] The utility model will be further described below with reference to the drawings.

[0018] According to Figure 1As shown in Figure 3, the utility model provides a steel bar connecting component for highway bridge construction, which comprises a bidirectional lead screw 1. The bidirectional lead screw 1 is rotatably arranged in a frame body 2. On both sides inside the frame body 2, there are respectively arranged lower moving blocks 3 threadedly connected to the bidirectional lead screw 1. The lower moving blocks 3 are hinged to upper moving blocks 4. In the middle of the upper end of the lower moving block 3 and the middle of the lower end of the upper moving block 4, there are corresponding semi-circular through grooves 5. The middle part of the upper moving block 4 is threadedly connected with an adjusting bolt 6. The lower moving blocks 3 and the upper moving blocks 4 are fixed by fixing bolts 7. The two ends of the bidirectional lead screw 1 pass through the frame body 2 through bearings, and cranks 8 are respectively arranged at both ends. One side of the lower moving block 3 is connected to the upper moving block 4 through a hinge 12. In the middle and lower part of the lower moving block 3, there is a first threaded hole 9 corresponding to the bidirectional lead screw 1. On the side far from the hinge 12 in the upper part, there is a second threaded hole 10 corresponding to the fixing bolt 7. In the middle part of the upper moving block 4, there is a third threaded hole 11 corresponding to the adjusting bolt 6. On the side far from the hinge 12, there is a second threaded hole 10 corresponding to the fixing bolt 7. In this way, when in use, first move the two lower moving blocks 3 away from each other, then rotate the upper moving block 5 to stagger the semi-circular through groove 5 of the upper moving block 5 and the lower moving block 3. Then place the steel bar into the semi-circular through groove 5 of the lower moving block 3. After that, use the fixing bolt 7 to fix the lower moving block 3 and the upper moving block 5, and the steel bar will be in the semi-circular through grooves 5 of the lower moving block 3 and the upper moving block 5. Then use the adjusting bolt 6 to fix the steel bar. Then rotate the bidirectional lead screw 1 through the crank 8 to make the two steel bars approach each other, so as to be connected. When the connection is completed, loosen the adjusting bolt 6 and remove the fixing bolt 7, and then the upper moving block 5 can be rotated, so as to facilitate the removal of the device.

[0019] Principle of the utility model: When in use, first place the device in the middle of the two steel bars to be connected on both sides. Then rotate the upper moving block 5 to stagger the semi-circular through groove 5 of the upper moving block 5 and the lower moving block 3. Then place the two steel bars on both sides into the semi-circular through grooves 5 of the two lower moving blocks 3 respectively. Then rotate the upper moving block 5 to make the upper moving block 5 above the lower moving block 3 and fix it with the fixing bolt 7. Then rotate the adjusting bolt 6 to fix the two steel bars. The two steel bars will be pressed and their axes will also coincide. Then rotate the bidirectional lead screw 1 through the crank 8 to make the two steel bars approach each other. Then connect the two steel bars. When the connection is completed, loosen the adjusting bolt 6 and remove the fixing bolt 7. Then rotate the upper moving block 5 and remove the device.
