Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel structure technology, and specifically relates to a positioning device for steel structure installation. Background Technology
[0002] The installation of steel structural components (such as beams and columns) requires repeated verification of their three-dimensional coordinates using high-precision measuring equipment. Positioning devices provide stable reference points, reducing human error and ensuring that indicators such as verticality and horizontality meet standards. The gaps at joints such as steel beams and nodes must be strictly controlled within the design range. Positioning devices can achieve a rotational locking function, preventing misalignment of contact surfaces or excessive gaps, thereby ensuring load-bearing capacity. If the positioned steel structure needs to be repositioned or moved laterally, the positioning device must be disassembled and reinstalled, increasing construction difficulty and labor costs.
[0003] In summary, existing technologies have the problem of being unable to quickly fine-tune the positioned steel structure, which is time-consuming and labor-intensive. Utility Model Content

[0015] The following is in conjunction with the appendix Figure 1-3 This utility model will be described in further detail below.
[0016] Example 1, refer to Figure 1-3 In this embodiment, to address the problem of existing technologies being unable to quickly fine-tune the positioned steel structure, which is time-consuming and labor-intensive, a positioning device for steel structure installation is disclosed. The device includes a clamping member 3 for clamping the steel structure. The inner side of the clamping member 3 has an anti-slip layer, and stabilizing plates 2 are fixed on both sides to initially define the position of the steel structure. A first air pump 4 is fixedly installed above the stabilizing plates 2. The first air pump 4 is connected to the clamping plate 1 via a telescopic rod. The clamping plate 1 has anti-slip textures. The clamping plate 1 is driven by the first air pump 4 to clamp, resulting in a smaller clamping gap and higher stability.
[0017] The rotating seat 6 is used for fine-tuning the horizontal and vertical directions of the steel structure. The clamping member 3 is fixed to the spiral block 13 by the jack 5, and the jack 5 is raised and lowered by the first rotating handle 9. The first rotating handle 9 is set on the outer side of the rotating seat 6. The spiral block 13 is fixed on the bidirectional screw 22. The bidirectional screw 22 is fixed inside the moving groove 14 and passes through the rotating seat 6 from left to right. It is connected to the second rotating handle 15 on the side of the rotating seat 6. The second rotating handle 15 controls the rotation of the bidirectional screw 22 and thus controls the left and right movement of the clamping member 3.
[0018] The base 7 is used for fine-tuning the horizontal rotation angle of the steel structure. The rotating seat 6 is connected to the fixed gear 17 through the stabilizing column 16. The fixed gear 17 is restricted by the fixed plate 25 at the center of the base 7. The fixed plate 25 is provided with multiple round holes, and the round holes are provided with ball bearings 23. Because the ball bearings 23 are embedded in the round holes, the ball bearings 23 will not be misaligned. The main function of the ball bearings 23 is to reduce friction and make horizontal rotation easier. The fixed gear 17 has a matching rack 19. The rack 19 and the fixed gear 17 are engaged to drive the rotation of the fixed gear 17, thereby completing the fine-tuning of the horizontal angle. One side of the rack 19 is connected to the third rotating handle 21 through the connecting column 20, and the other side is connected to the positioning block 18. The third rotating handle 21 is mainly used to push and pull to complete the horizontal movement of the rack 19, thereby driving the fine-tuning of the horizontal angle of the steel structure. The length ratio of the rack 19 to the connecting column 20 is 1:2. The slide groove 24 occupies 1 / 2 of the length of the base 7. The total length of the toothed rod 19 and the connecting post 20 occupies 3 / 4 of the length of the base 7. Initially, the positioning block 18 is located in the middle of the slide groove 24. This allows for fine-tuning at a 45-degree angle to the left and right. To ensure the stability of the fine-tuning, the connecting post 20 has an anti-slip layer on its outer ring. A fixing block 10 is installed on the side of the base 7 and the third rotating handle 21. A limit block 12 is provided on the outer side of the fixing block 10 to ensure the stability of the fixing rod 11 fitted onto the fixing block 10. The bottom of the fixing rod 11 is a non-fully enclosed ring, which is a 3 / 4 ring with an anti-slip layer on its inner side. This ring is compatible with the connecting post 20, and the length of the fixing rod 11 is also compatible with the connecting post 20. Optionally, the fixing block 10 is located in the lower half of the horizontal part of the third rotating handle 21. When the fixing rod 11 fixes the connecting post 20, it will generate a pulling force.
[0019] Specific implementation principle: When using this utility model, firstly, the steel structure is placed on the clamping member 3, and the first air pump 4 is started. The first air pump 4 pushes the clamping plate 1 to further clamp the steel structure. According to the on-site construction needs, the first rotating handle 9, the second rotating handle 15, or the third rotating handle 21 are adjusted. The first rotating handle 9 mainly rotates in different directions, causing the pawl to push the ratchet to rotate back, and the small bevel gear drives the large bevel gear, causing the lifting screw to rotate, thereby raising or lowering the lifting sleeve, that is, raising or lowering the jack 5, and completing the fine adjustment in the vertical direction. The second rotary handle 15 mainly controls the rotation of the bidirectional screw 22 to move the spiral block 13 left and right, thus enabling fine-tuning in the horizontal direction. Pushing or pulling the third rotary handle 21 causes the fixed gear 17 to rotate counterclockwise under the action of the rack 19 when pushed inward, and the rotating seat 6 to rotate horizontally to the right. After the position is determined, it is fixed by the fixing rod 11. When the third rotary handle 21 is pulled, the rack 19 moves to the left, the fixed gear 17 rotates clockwise, and the rotating seat 6 rotates horizontally to the left. Similarly, after the position is determined, it is fixed. Because there is already resistance between the gears, the fixing rod 11 further reinforces it. Due to the friction, the device remains stable at the required angle. However, it is worth noting that this device is for fine-tuning and cannot meet the horizontal rotation requirements of 45 degrees and above.
[0020] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
