Description

Technical Field

[0001] This utility model relates to the field of light steel keel technology, specifically to an adjustable modular light steel keel. Background Technology

[0002] Light steel keel is a metal frame material made from high-quality continuous hot-dip galvanized steel sheet through cold bending process. It is widely used in interior partition walls, ceilings and other building decoration projects. Its core advantages are lightweight and high strength. The main keel wall thickness is usually 0.8 to 1.2 mm. With U-shaped, C-shaped and L-shaped cross-section designs, it can form a high-rigidity structure with a single-point load-bearing capacity of more than 50 kg, which can meet the suspension requirements of lighting fixtures, air conditioners and other equipment. In terms of material properties, the anti-corrosion treatment with a zinc coating thickness of ≥8μm gives it excellent moisture resistance and corrosion resistance, with a service life of more than 20 years. When used with gypsum board, calcium silicate board and other boards.

[0003] Currently, the construction of irregular curved light steel keel partition walls faces three major industry pain points: loss of precision control, low efficiency, and performance defects. Specifically, the processing of curved keels is highly dependent on on-site cutting and manual bending, which often results in curvature errors exceeding 5mm, leading to uneven gypsum board joints, affecting the overall aesthetics and construction quality. At the same time, for the construction of ultra-high walls, traditional processes require multiple layers of horizontal keels for reinforcement, with an average construction time of up to 3.5 person-days for a single wall, which is extremely inefficient. Therefore, we need adjustable modular light steel keels. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable modular light steel keel to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable modular light steel keel, including an arc-shaped keel, a quick-release assembly on one side of the arc-shaped keel, a supporting keel on one side of the arc-shaped keel, an adjustment assembly on the supporting keel, the adjustment assembly including a bolt sleeve, the bolt sleeve being fixed to the bottom of the arc-shaped keel, a bolt head being connected to the internal thread of the bolt sleeve, a supporting sleeve being fixedly connected to the end of the bolt head away from the bolt sleeve, an adjustment screw being connected to the internal thread of the supporting sleeve, and a pad being rotatably connected to the end of the adjustment screw away from the supporting sleeve.

[0007] Preferably, the support sleeve and the adjusting screw form a threaded structure, and the outer diameter of the adjusting screw matches the inner diameter of the support sleeve, and the outer wall of the adjusting screw is fitted into the interior of the support sleeve.

[0008] Preferably, the support sleeve forms a movable structure with the pad through an adjusting screw, and one end of the adjusting screw extends into the support sleeve for connection, and the bottom of the adjusting screw is connected to the top of the pad.

[0009] Preferably, the quick-release assembly includes a limiting groove, which is formed on the arc-shaped keel. A side plate frame is fitted inside the limiting groove. The side plate frame is connected to the arc-shaped keel by a long bolt. One end of the long bolt is threaded with a nut. The side plate frame has a positioning hole.

[0010] Preferably, the arc-shaped keel forms an engaging structure with the supporting keel through a limiting groove, and the size of the limiting groove matches the size of the supporting keel, the inner diameter of the limiting groove matches the outer diameter of the supporting keel, and the inner wall of the limiting groove fits snugly against the outer wall of the supporting keel.

[0011] Preferably, the number of limiting grooves on the arc-shaped keel is multiple, and the multiple limiting grooves are evenly spaced on one side of the arc-shaped keel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the scheme of this application:

[0015] 1. To address the problems of cumbersome installation process, low splicing efficiency, and insufficient stability of existing curved keel systems, this application proposes a modular curved keel design. After factory processing, the curved keel is transported to the site for assembly. During installation, the supporting keel is first fixed to the wall, and the curved keel is secured to the outer wall of the supporting keel using its internal limiting groove. The side panel frame is positioned accordingly, and long bolts are then inserted through the positioning holes in the side panel frame and the supporting keel, and tightened with nuts. This achieves rapid splicing and stable installation of the curved keel and the supporting keel, significantly improving construction efficiency and reducing installation difficulty and cost.

[0016] 2. To address the problems of inconvenient support adjustment and difficulty in flexibly adapting to different construction scenarios and accurately adjusting the keel position in existing light steel keel frames, this application proposes a design where bolt sleeves are welded to the bottom of the arc-shaped keel, and the support sleeve is secured within the bolt sleeve by the bolt head. Rotating the adjusting screw causes it to rotate within the support sleeve, moving the pad to fit against the arc-shaped keel. This achieves effective support for the overall light steel keel frame while allowing for convenient position adjustment of the arc-shaped keel, meeting the need for flexible keel adjustments during daily construction, improving construction efficiency and quality, and enhancing the adaptability and stability of the structure.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] This utility model embodiment provides an adjustable modular light steel keel, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the device includes an arc-shaped keel 1, a quick-release assembly 2 on one side of the arc-shaped keel 1, a supporting keel 3 on one side of the arc-shaped keel 1, and an adjusting assembly 4 on the supporting keel 3. The adjusting assembly 4 includes a bolt sleeve 401, which is fixed to the bottom of the arc-shaped keel 1. A bolt head 402 is threaded into the bolt sleeve 401. A supporting sleeve 403 is fixedly connected to the end of the bolt head 402 away from the bolt sleeve 401. The interior of the supporting sleeve 403... An adjusting screw 404 is threadedly connected. The end of the adjusting screw 404 away from the support sleeve 403 is rotatably connected to a pad 405. By rotating the adjusting screw 404, it can rotate within the support sleeve 403, causing the adjusting screw 404 to move the pad 405 and make it fit against the bottom arc-shaped keel 1. At this time, it can be used to support the overall light steel keel frame, and at the same time, the position of the arc-shaped keel 1 can be adjusted, which can meet the needs of daily construction adjustment of the keel.

[0024] Further such as Figure 2 and Figure 4 As shown, the bolt sleeve 401 forms a detachable structure with the arc-shaped keel 1 through the bolt head 402, and the outer diameter of the bolt head 402 matches the inner diameter of the bolt sleeve 401. The outer wall of the bolt head 402 is tightly fitted with the inner wall of the bolt sleeve 401. Through the bolt head 402, the bolt head 402 can be fastened in the bolt sleeve 401 for fixation, which can facilitate the quick fixation of the adjustment component 4 and the arc-shaped keel 1.

[0025] Further such as Figure 2 and Figure 4 As shown, the support sleeve 403 and the adjusting screw 404 form a threaded structure, and the outer diameter of the adjusting screw 404 matches the inner diameter of the support sleeve 403. The outer wall of the adjusting screw 404 is fitted into the interior of the support sleeve 403, which strengthens the connection between the support sleeve 403 and the adjusting screw 404. This allows the adjusting screw 404 to rotate within the support sleeve 403, making it easy to adjust the extension length of the adjusting screw 404.

[0026] Further such as Figure 2 and Figure 4 As shown, the support sleeve 403 forms a movable structure with the pad 405 through the adjusting screw 404. One end of the adjusting screw 404 extends into the support sleeve 403 for connection, and the bottom of the adjusting screw 404 is connected to the top of the pad 405, which enhances the connection effect between the adjusting screw 404 and the pad 405. This allows the adjusting screw 404 to drive the pad 405 to fit and push against the arc-shaped keel 1, which facilitates the adjustment of the spacing between the arc-shaped keels 1.

[0027] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the quick-release assembly 2 includes a limiting groove 201, which is formed on the arc-shaped keel 1. A side plate frame 202 is fitted inside the limiting groove 201. The side plate frame 202 is connected to the arc-shaped keel 1 by a long bolt 203. One end of the long bolt 203 is threaded with a nut 204. The side plate frame 202 has a positioning hole 205. By modularly designing the arc-shaped keel 1 and processing it in the factory, it can be taken to the construction site for assembly. In addition, during assembly, it can be directly... After fixing the supporting keel 3 to one side of the wall, the curved keels 1 can be installed in sequence. The curved keel 1 can be locked onto the outer wall of the supporting keel 3 by the internal limiting groove 201. The side plate frames 202 on both sides of the curved keel 1 can position the supporting keel 3. The long bolts 203 pass through the positioning holes 205 inside the side plate frames 202 and the supporting keel 3, and are then tightened by the nuts 204. Thus, the quick splicing and installation of the curved keel 1 and the supporting keel 3 can be completed.

[0028] Further such as Figure 3 and Figure 4 As shown, the arc-shaped keel 1 and the supporting keel 3 form a locking structure through the limiting groove 201. The size of the limiting groove 201 matches the size of the supporting keel 3, and the inner diameter of the limiting groove 201 matches the outer diameter of the supporting keel 3. The inner wall of the limiting groove 201 fits against the outer wall of the supporting keel 3, which enhances the connection between the supporting keel 3 and the arc-shaped keel 1. This allows the supporting keel 3 to be locked in the limiting groove 201 inside the arc-shaped keel 1 for fastening and installation, and facilitates quick and stable connection between the arc-shaped keel 1 and the supporting keel 3.

[0029] Further such as Figure 3 and Figure 4 As shown, there are multiple limiting grooves 201 on the arc-shaped keel 1, and the multiple limiting grooves 201 are evenly spaced on one side of the arc-shaped keel 1. By setting multiple limiting grooves 201 on the arc-shaped keel 1, it is convenient to install the arc-shaped keel 1 on the supporting keel 3 for fixing, which can facilitate the positioning and installation of the arc-shaped keel 1.

[0030] Further such as Figure 3 and Figure 4As shown, the side plate frame 202 is connected to the support keel 3 by long bolts 203 to form a detachable structure. One end of the long bolt 203 passes through the positioning hole 205 inside the side plate frame 202 and the support keel 3 and is connected to the nut 204. By using the long bolt 203, the arc-shaped keel 1 can be installed on the support keel 3 for reinforcement, which improves the efficiency of quick installation and disassembly of the arc-shaped keel 1.

[0031] Working principle: During use, the curved keel 1 is modularly designed and processed in the factory, then assembled on the construction site. During assembly, the supporting keel 3 can be directly fixed to one side of the wall, and the curved keels 1 can be installed sequentially. The curved keel 1 can be secured to the outer wall of the supporting keel 3 by its internal limiting groove 201. The side panels 202 on both sides of the curved keel 1 can position the supporting keel 3. Long bolts 203 penetrate the side panels 202 and the positioning holes 205 inside the supporting keel 3, and are then tightened with nuts 204. This allows for quick splicing and installation of the arc-shaped keel 1 and the supporting keel 3. Furthermore, by welding the bolt sleeve 401 to the bottom of the arc-shaped keel 1, the supporting sleeve 403 can be fastened inside the bolt sleeve 401 by the bolt head 402. At this time, by rotating the adjusting screw 404, the adjusting screw 404 can rotate inside the supporting sleeve 403, causing the adjusting screw 404 to move the pad 405 and fit it against the bottom arc-shaped keel 1. This can be used to support the overall light steel keel frame and adjust the position of the arc-shaped keel 1, meeting the needs of daily construction keel adjustment.
