Technical Field
[0001] This utility model relates to the field of back ribs, and in particular to a novel light steel keel back rib. Background Technology
[0002] In the complex and demanding field of building construction, especially in the crucial concrete pouring formwork support system, the light steel keel back rib plays an indispensable and extremely important reinforcing role as a crucial component. It plays a vital and irreplaceable role in ensuring the stability of the formwork during construction and the final quality of the concrete.
[0003] However, most existing back ribs have significant shortcomings. First, they cannot be conveniently adjusted in length. Due to the inconsistent size of the formwork, back ribs that cannot be adjusted in length are difficult to adapt to various specifications, requiring construction parties to prepare back ribs of various lengths, increasing procurement costs, causing storage and management difficulties, and making it impossible to meet special size requirements in a timely manner, which may delay the construction progress. Second, their splicing performance is poor. When splicing is required for the reinforcement of large-area formwork, the existing back rib splicing process is complicated, time-consuming and labor-intensive, and the stability is difficult to guarantee, which limits their application in large-scale formwork projects and reduces construction efficiency and flexibility.
[0004] Therefore, those skilled in the art have provided a novel light steel keel back rib to solve the problems mentioned in the background art. Summary of the Invention

Compared to most existing back braces, this novel light steel keel back brace features a connector at the front end of the main back brace, with a second limiting groove inside the connector. A second spring and a second adjusting component are connected within the second limiting groove. A connected component is located at the rear end of the secondary back brace, with a second sliding groove and a second limiting hole inside the connected component. By connecting the front end of the connector to the rear end of the connected component, the two back braces can be firmly spliced together. This improves and simplifies the splicing process, saves manpower and time, and enhances construction efficiency and flexibility.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Reference Figure 1-5 One embodiment provided by this utility model:
[0036] A novel light steel keel back rib includes a main back rib 1. Multiple first limiting holes 5 are provided on the outer walls of both sides of the main back rib 1. First sliding grooves 10 are provided on both sides of the inner top and inner bottom surfaces of the main back rib 1. A secondary back rib 3 is slidably connected to the rear end of the inner wall of the main back rib 1. Slider blocks 9 are fixedly connected to both sides of the upper and lower surfaces of the secondary back rib 3. Connecting pieces 7 are fixedly connected to both sides of the middle part of the front outer wall of the main back rib 1. A second limiting groove 15 is provided at the front end of the upper surface of the connecting piece 7. A second spring 16 is fixedly connected to the inner bottom surface of the second limiting groove 15.
[0037] The upper surface of the second spring 16 is fixedly connected to the second adjusting member 8. Both sides of the outer wall of the rear end of the secondary back rib 3 are fixedly connected to the connected member 4. Both sides of the inner bottom surface of the secondary back rib 3 are fixedly connected to the connecting block 11. The middle of the outer wall of the connecting block 11 is provided with the first limiting groove 14. The inner wall of the first limiting groove 14 near the secondary back rib 3 is fixedly connected to the lifting rod 12. The end of the lifting rod 12 away from the connecting block 11 is fixedly connected to the first adjusting member 6. The periphery of the outer wall of the first adjusting member 6 near the lifting rod 12 is fixedly connected to the first spring 13.
[0038] The above technical solutions help to achieve convenient adjustment of back rib length, improve back rib splicing performance, reduce procurement costs, optimize on-site management and avoid construction delays, simplify splicing process, save manpower and time, ensure splicing stability, and also broaden the application scope and improve construction efficiency and flexibility.
[0039] The end of the first spring 13 furthest from the first adjusting member 6 is fixedly connected to the connecting block 11. This fixed connection allows the first adjusting member 6 to pop out. The connecting member 7 engages with the connected member 4 via the second adjusting member 8. This engagement facilitates easier splicing of the two back ribs during use. Rubber blocks 19 are fixedly connected to the four corners of the inner rear wall of the main back rib 1, providing better protection and extending its lifespan. Multiple first pre-drilled holes 2 are provided on both sides of the upper surface of the main back rib 1, and multiple second pre-drilled holes 20 are provided on both sides of the upper surface of the secondary back rib 3. Multiple first reserved holes 2 are provided on both sides of the upper surface of the main back rib 1, and multiple second reserved holes 20 are provided on both sides of the upper surface of the secondary back rib 3. This reduces the overall weight of the back ribs and facilitates handling. The first adjusting member 6 engages with the first limiting hole 5, allowing the secondary back rib 3 to slide within the main back rib 1 and adjust its length. The upper surface of the connected member 4 has a second limiting hole 18, which allows it to engage with the second adjusting member 8. The outer wall of the rear end of the connected member 4 has a second sliding groove 17, which allows the connecting member 7 to engage with the connected member 4 more conveniently.
[0040] Working principle: In use, the user presses the first adjusting piece 6, and at the same time the lifting rod 12 and the first spring 13 retract. Then, by pushing and pulling the secondary back rib 3, the slider 9 slides in the first slide groove 10. After reaching the appropriate length, the user releases the first adjusting piece 6, and the first spring 13 pops the first adjusting piece 6 out of the first limiting hole 5, thereby adjusting the length of the back rib. The user aligns the connecting piece 7 on the main back rib 1 with the connected piece 4 on the secondary back rib 3, and then presses the second adjusting piece 8. The second adjusting piece 8 is subjected to external pressure and enters the second limiting groove 15. Then, the connecting piece 7 slides in the second slide groove 17 inside the connected piece 4. After reaching the predetermined position, the user releases the second adjusting piece 8, and the second spring 16 pops out from the second limiting hole 18, thus completing the splicing of the two back ribs.
