Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a connector for an adjustable channel steel formwork. Background Technology

[0002] In the construction industry, channel steel formwork is widely used in concrete pouring, structural support and other scenarios due to its high strength, good stability and reusability. However, in actual construction, channel steel formwork often needs to be combined and spliced ​​according to different construction structures. The length and angle of a single channel steel section often cannot directly meet the requirements of complex working conditions. Therefore, it is necessary to use connectors to realize the rapid assembly and fixing of multiple channel steel sections in order to form an overall formwork system that meets the construction requirements.

[0003] Channel steel formwork connectors are mostly fixed by direct bolt fastening or welding. When using them, the two ends of the connector are first aligned with the connecting ends of the two channel steel sections, and bolts are inserted and tightened through the pre-set bolt holes to form a rigid connection between the connector and the channel steel. In the case of no pre-set bolt holes, the connector and the channel steel need to be fixed together by welding to ensure that the spliced ​​formwork structure does not shift or deform under construction load. However, the bolt fastening or welding method makes it difficult to flexibly adjust the height and angle of the channel steel formwork. When the construction conditions require fine adjustment of the formwork tilt or height difference, the connector needs to be disassembled and re-drilled or welded, which is not only cumbersome but also damages the structural integrity of the channel steel and the connector. Therefore, in order to solve this problem, we propose an adjustable channel steel formwork connector. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an adjustable connector for channel steel formwork, which can flexibly adjust the angle of the mounting plate to meet the tilt or height requirements of channel steel formwork under different working conditions. This avoids the need to disassemble the connector for re-drilling or welding, as well as the damage to the structural integrity of the channel steel and the connector. It can effectively prevent the channel steel formwork from shifting or shaking due to changes in spacing, improve the load-bearing capacity and overall construction stability, and reduce the safety risks caused by spacing adjustment issues.

Beneficial effects

[0013] 1. The connector of the adjustable channel steel formwork in this technical solution can easily adjust the lifting height of the first threaded rod by rotating the nut and engaging the thread with the first threaded rod. Combined with the movement of the universal ball in the limiting sleeve, the angle of the mounting plate can be flexibly adjusted to meet the tilt or height requirements of the channel steel formwork under different working conditions. This avoids the need to disassemble the connector for re-drilling or welding, as well as damage to the structural integrity of the channel steel and the connector.

[0014] 2. The threaded engagement between the second threaded rod and the telescopic sleeve allows the stop plate to be precisely engaged in the limiting groove of the channel steel formwork. This enables flexible adjustment of the spacing between the channel steel formwork panels, avoiding construction restrictions caused by fixed spacing. After the spacing adjustment is completed, the tight fit between the baffle and the channel steel formwork, as well as the limiting effect of the stop plate, effectively prevents the channel steel formwork from shifting or shaking due to changes in spacing. This improves the load-bearing capacity and overall construction stability, and reduces safety risks caused by spacing adjustment issues. Attached Figure Description

[0019] Specifically, the rotating nut 6 has an internal thread, and the first threaded rod 7 has an external thread. The rotating nut 6 and the first threaded rod 7 are threadedly connected. The threaded connection between the rotating nut 6 and the first threaded rod 7 makes it easy for the rotating nut 6 to drive the first threaded rod 7 to move.

[0020] Specifically, a sliding plate 21 is fixedly installed below the first threaded rod 7. The sliding plate 21 can be used to raise and lower the first threaded rod 7. The support sleeve 5 has a sliding groove 22 adapted to the sliding plate 21. The sliding groove 22 can limit the first threaded rod 7. The sliding plate 21 can limit the first threaded rod 7 when it is raised and lowered inside the sliding groove 22. When the sliding plate 21 slides inside the sliding groove 22, the movement of the first threaded rod 7 can be made more stable.

[0021] Specifically, a first limiting plate 11 is fixedly installed on the top of the mounting plate 10. The second threaded rod 12 can be supported by the first limiting plate 11 for operation. The second threaded rod 12 is movably fitted inside the first limiting plate 11. The distance of the channel steel template 1 can be adjusted at any time by the same second threaded rod 12. A rotating handle 13 is fixedly installed on the outside of the second threaded rod 12. The rotating handle 13 is set on both sides of the outside of the first limiting plate 11. When the rotating handle 13 is set on both sides of the outside of the first limiting plate 11, it is convenient to rotate the second threaded rod 12.

[0022] Specifically, a second limiting plate 14 is fixedly installed on both sides of the upper part of the mounting plate 10. The second limiting plate 14 can limit the telescopic sleeve 15, which facilitates the movement of the telescopic sleeve 15. The telescopic sleeve 15 is provided inside the second limiting plate 14. The distance between the channel steel templates 1 can be easily adjusted through the telescopic sleeve 15. The telescopic sleeve 15 is threadedly connected to the second threaded rod 12. When the telescopic sleeve 15 is threadedly connected to the second threaded rod 12, the telescopic sleeve 15 can be driven to move through the second threaded rod 12.

[0023] Specifically, a first positioning plate 16 is fixedly installed on the outside of the telescopic sleeve 15, and a groove adapted to the first positioning plate 16 is opened inside the second limiting plate 14.

One side surface of the second positioning plate 20 is in close contact with one side surface of the second limiting plate 14. The telescopic sleeve 15 can be limited by the second positioning plate 20 to prevent the telescopic sleeve 15 from moving excessively.

[0026] Working Principle: The overall device is supported by base 2. The fixed plate 3 above base 2 provides a hinge fulcrum for support plate 4, allowing support plate 4 to be adjusted to a certain angle. The support sleeve 5 above support plate 4 facilitates height and angle adjustment. The first threaded rod 7, which is movably fitted inside the sleeve, is threaded with the rotating nut 6. The internal thread of the rotating nut 6 is adapted to the external thread of the first threaded rod 7. When the rotating nut 6 is rotated, the first threaded rod 7 can be driven to move up and down within the support sleeve 5. The sliding plate 21 below the first threaded rod 7 slides in the sliding groove 22 adapted inside the support sleeve 5, which limits and guides the movement of the first threaded rod 7 to prevent it from deviating. The limiting sleeve 8 above the first threaded rod 7 is equipped with a universal ball 9, which can rotate flexibly within the limiting sleeve 8, thereby driving the fixed mounting plate 10 above to adjust its angle to adapt to different tilt requirements of the channel steel template 1. The first limiting plate 11 above the mounting plate 10... The second threaded rod 12 is provided with movable support. By rotating the rotating handle 13 on the outside of the second threaded rod 12, the second threaded rod 12 can be driven to rotate. Since the second threaded rod 12 is threadedly connected to the telescopic sleeve 15 inside the second limiting plate 14, and the first positioning plate 16 on the outside of the telescopic sleeve 15 slides and limits in the slot opened in the second limiting plate 14, the rotation of the second threaded rod 12 will drive the telescopic sleeve 15 to perform horizontal telescopic movement. The second positioning plate 20 at the end of the telescopic sleeve 15 away from the stop plate 17 is in close contact with the surface of the second limiting plate 14, further ensuring the stability of the telescopic sleeve 15 during telescopic movement. When the telescopic sleeve 15 telescopically moves, the stop plate 17 at one end will be precisely engaged in the limiting slot 19 opened in the channel steel template 1. At the same time, the baffle 18 at one end of the stop plate 17 is in close contact with the channel steel template 1, thereby fixing the channel steel template 1. By adjusting the telescopic amount of the telescopic sleeve 15, the spacing between the channel steel templates 1 can be flexibly adjusted, and the channel steel templates 1 can be effectively prevented from shifting or shaking.
