Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a multi-directional fine-adjustment connection device for lightweight steel structures in buildings. Background Technology

[0002] In the construction industry, it is often necessary to erect lightweight decorative steel structures on top of the main building structure. During erection, connectors (such as multiple parallel installation columns) are typically pre-embedded in the main building structure. The lightweight decorative steel structure is then connected to these pre-embedded connectors using support rods, allowing the lightweight decorative steel structure to form an outward-extending decorative element. Currently, the support rods are typically steel pipes with hinged lugs at one end. During connection, one end of the support rod is first hinged to the lightweight decorative steel structure via the hinge lug. The angle of the lightweight decorative steel structure is then adjusted using the support rod. After adjustment, both ends of the support rod are welded or locked to the lightweight decorative steel structure and the pre-embedded connectors, respectively, thus fixing the position of the lightweight decorative steel structure.

[0003] However, as decorative components, lightweight decorative steel structures vary in shape at different locations and typically extend quite a distance. Therefore, a large number of support rods are required, and each rod needs to be manufactured to different lengths based on the distance between its location and the embedded connector. This results in high costs and significant time consumption. Furthermore, during installation, the angle of the lightweight decorative steel structure needs to be adjusted using the support rods. Even with pre-measured lengths, the support rods often end up being too long or too short. This necessitates changing the connection position between the support rod and the embedded connector, leading to deviations from the intended position and affecting the overall decorative effect of the decorative component. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a multi-directional fine-adjustment connection device for lightweight steel structures in buildings. This multi-directional fine-adjustment connection device can be used to connect different positions of various lightweight decorative steel structures without special customization, with low cost and can effectively improve construction efficiency.

[0005] To solve the above technical problems, the following technical solution is adopted:

[0006] A multi-directional fine-tuning connection device for lightweight steel structures in buildings is characterized by comprising a mounting base, a telescopic support rod, and a clamping mechanism. The two ends of the telescopic support rod are respectively hinged to the mounting base and the clamping mechanism. A first locking mechanism is provided at the hinge points of the two ends of the telescopic support rod, and a second locking mechanism is provided at the clamping part of the clamping mechanism.

[0007] When using the aforementioned multi-directional fine-tuning connection device, the mounting base is first fixedly installed on the pre-embedded connector of the main building structure, allowing the telescopic support rod to extend outwards. Then, according to the desired location of the lightweight decorative steel structure, the telescopic support rod is adjusted so that the clamping mechanism on the telescopic support rod corresponds to the connecting part on the lightweight decorative steel structure, and the clamping mechanism clamps the connecting part. Finally, after fine-tuning the positions of the telescopic support rod and the clamping mechanism as needed, the position of the telescopic support rod is fixed by the first locking mechanism, and the clamping mechanism is locked to the connecting part of the lightweight decorative steel structure by the second locking mechanism. This multi-directional fine-tuning connection device can be used to connect various lightweight decorative steel structures at different locations without requiring special customization based on the distance between the steel structure and the pre-embedded connector. It allows for arbitrary adjustment of length and angle, effectively reducing costs and improving construction efficiency. Furthermore, when each mounting base is set on the pre-embedded connector, they can be uniformly installed in the same row (i.e., the mounting bases can be installed on the same horizontal line as the pre-embedded connector), resulting in a more visually uniform extension position of each telescopic support rod, contributing to a smoother and more aesthetically pleasing decoration.

[0008] In a preferred embodiment, the multi-directional fine-tuning connection device further includes an auxiliary support rod, one end of which is hinged to the outer wall of the telescopic support rod. The other end of the auxiliary support rod can be hinged to a pre-embedded connector or to a lightweight decorative steel structure. The auxiliary support rod is used to assist in adjusting the position of the telescopic support rod, and can be removed after the telescopic support rod has been adjusted.

[0009] In a preferred embodiment, the telescopic support rod includes an outer sleeve, a guide rod, and multiple locking components. The inner end of the outer sleeve is fitted onto the guide rod. The inner end of the outer sleeve has multiple first positioning through holes along its length, and the guide rod has multiple second positioning through holes along its length. The locking components pass through the first and second positioning through holes sequentially, connecting the outer sleeve and the guide rod. After adjusting the length of the guide rod extending beyond the outer sleeve according to the distance between the steel structure and the embedded connectors, the locking components lock the positions of the outer sleeve and the guide rod. The locking components can be made using a bolt and nut combination; the bolt passes through the corresponding positioning through hole and engages with the nut threadedly.

[0010] In a preferred embodiment, the first locking mechanism includes a first bolt and a first nut. The telescopic support rod has first through holes at both ends, and the mounting base and clamping mechanism have second through holes at their ends. The first bolt passes through the first and second through holes sequentially and is threadedly connected to the first nut. When adjusting the position, the first nut can be loosened first. In this loosened state, the first bolt acts as a hinge point at the end of the telescopic support rod, allowing the telescopic support rod to swing around the mounting base and the clamping mechanism to swing around the end of the telescopic support rod, thus saving on the hinge shaft. After adjustment, the first nut can be tightened to lock the positions of the telescopic support rod and the clamping mechanism respectively.

[0011] In a preferred embodiment, the clamping mechanism employs hydraulic grippers. Typically, the two clamping portions of the hydraulic grippers are parallel straight plates, and the connecting portion of the lightweight decorative steel structure is a lifting ring or plate extending outward from the end face of the lightweight decorative steel structure; during clamping, the two clamping portions of the hydraulic grippers together clamp the connecting portion.

[0012] In a further preferred embodiment, the hydraulic gripper has two opposing clamping portions, each with a corresponding third through hole. The second locking mechanism includes a second bolt and a second nut, the second bolt passing through the two third through holes and threadedly connected to the second nut. Typically, the connecting portion of a lightweight decorative steel structure has a through hole matching the third through hole. After position adjustment, the clamping portion can be clamped onto the connecting portion and its position fixed by tightening the second bolt and the second nut.

[0013] The reason why nuts and bolts are used for locking in the above-mentioned locking structures and telescopic support rods is that the lightweight decorative steel structure is relatively light and only serves a decorative purpose, without bearing any weight. Therefore, the requirement for support strength is low, and the above-mentioned structure can meet the needs.

[0014] The beneficial effects of this utility model are as follows: this multi-directional fine-tuning connection device can be used to connect different positions of various lightweight decorative steel structures without special customization, has low cost, and can effectively improve construction efficiency.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1-4 The multi-directional fine-tuning connection device for lightweight steel structures in buildings shown includes a mounting base 1, a telescopic support rod 2, and a clamping mechanism 3. The two ends of the telescopic support rod 2 are respectively hinged to the mounting base 1 and the clamping mechanism 3. The two ends of the telescopic support rod 2 are respectively provided with a first locking mechanism 4 at the hinge points. The clamping part 301 of the clamping mechanism 3 is provided with a second locking mechanism 5.

[0021] When using the above-mentioned multi-directional fine-tuning connection device, firstly, the mounting base 1 is fixedly installed on the pre-embedded connector 6 of the main building structure, so that the telescopic support rod 2 can extend to the outside; then, according to the position of the lightweight decorative steel structure 7 to be installed, the telescopic support rod 2 is adjusted so that the clamping mechanism 3 on the telescopic support rod 2 corresponds to the connecting part 8 on the lightweight decorative steel structure 7, and the clamping mechanism 3 clamps the connecting part 8; finally, after fine-tuning the position of the telescopic support rod 2 and the clamping mechanism 3 as needed, the position of the telescopic support rod 2 is fixed by the first locking mechanism 4, and the clamping mechanism 3 is locked on the connecting part 8 of the lightweight decorative steel structure 7 by the second locking mechanism 5. This multi-directional fine-tuning connection device can be used to connect various lightweight decorative steel structures 7 at different locations without the need for special customization based on the distance between the steel structure and the pre-embedded connector 6. It can adjust the length and angle at will, effectively reducing costs and improving construction efficiency. Furthermore, when each mounting seat 1 is set on the pre-embedded connector 6, it can also be uniformly installed on the same row (i.e., the mounting seat 1 can be installed on the same horizontal line of the pre-embedded connector 6), making the extension positions of each telescopic support rod 2 more uniform and helping to improve the smoothness and aesthetics of the decoration.

[0022] The multi-directional fine-tuning connection device also includes an auxiliary support rod 9, one end of which is hinged to the outer wall of the telescopic support rod 2. The other end of the auxiliary support rod 9 can be hinged to the pre-embedded connector 6 or to the lightweight decorative steel structure 7. The auxiliary support rod 9 is used to assist in adjusting the position of the telescopic support rod 2. After the telescopic support rod 2 has been adjusted, the auxiliary support rod 9 can be removed.

[0023] The telescopic support rod 2 includes an outer sleeve 201, a guide rod 202, and multiple locking components 203. The inner end of the outer sleeve 201 is fitted onto the guide rod 202. The inner end of the outer sleeve 201 has multiple first positioning through holes 2011 along its length, and the guide rod 202 has multiple second positioning through holes 2021 along its length. The locking components 203 pass through the first positioning through holes 2011 and the second positioning through holes 2021 in sequence, connecting the outer sleeve 201 and the guide rod 202. After adjusting the length of the guide rod 202 extending beyond the outer sleeve 201 according to the distance between the steel structure and the pre-embedded connector 6, the locking components 203 lock the positions of the outer sleeve 201 and the guide rod 202. The locking components 203 can be installed using a bolt and nut combination; the bolt passes through the corresponding positioning through hole and engages with the nut threadedly.

[0024] The first locking mechanism 4 includes a first bolt 401 and a first nut 402. The telescopic support rod 2 has first through holes at both ends, and the mounting base 1 and clamping mechanism 3 have second through holes at their ends. The first bolt 401 passes through the first and second through holes sequentially and is threadedly connected to the first nut 402. When adjusting the position, the first nut 402 can be loosened first. In the loosened state, the first bolt 401 serves as the hinge point at the end of the telescopic support rod 2, allowing the telescopic support rod 2 to swing around the mounting base 1, and the clamping mechanism 3 to swing around the end of the telescopic support rod 2, thus saving the hinge shaft. After adjustment, the first nut 402 can be tightened, thereby locking the positions of the telescopic support rod 2 and the clamping mechanism 3 respectively.

[0025] The clamping mechanism 3 uses hydraulic grippers. The two clamping parts 301 on the hydraulic grippers are parallel straight plates, and the connecting part 8 of the lightweight decorative steel structure 7 is a lifting ring or lifting plate extending outward from the end face of the lightweight decorative steel structure 7; when clamping, the two clamping parts 301 of the hydraulic grippers together clamp the connecting part 8.

[0026] The hydraulic gripper has two opposing gripping portions 301, each with a corresponding third through hole. The second locking mechanism 5 includes a second bolt 501 and a second nut 502. The second bolt 501 passes through the two third through holes and is threadedly connected to the second nut 502. The connecting portion 8 on the lightweight decorative steel structure 7 has a through hole that matches the third through hole. After the position is adjusted, the gripping portion 301 can be clamped onto the connecting portion 8 and its position fixed by locking the second bolt 501 and the second nut 502.

[0027] The reason why the locking structure and telescopic support rod 2 can be locked by means of nuts and bolts is that the lightweight decorative steel structure 7 is lightweight and only serves a decorative purpose and does not need to bear weight. Therefore, the requirement for support strength is low, and the above structure can meet the requirements.
