Description

Technical Field

[0001] The utility model relates to the technical field of docking structures, in particular to a docking structure for prefabricated light steel buildings. Background Art

[0002] A prefabricated building refers to a building in which a large amount of on-site work in the traditional construction method is transferred to the factory. Building components and fittings such as floor slabs, wall panels, stairs, balconies, etc. are processed and manufactured in the factory and transported to the construction site, and are assembled and installed on-site through reliable connection methods. Prefabricated buildings mainly include precast prefabricated concrete structures, steel structures, modern timber structures, etc. Because of the adoption of standardized design, factory production, assembly construction, information management, and intelligent application, it is a representative of modern industrial production methods.

[0003] After retrieval, a docking structure for a prefabricated light steel building with the publication number of CN217580607U includes an upper fixing column. The bottom of the upper fixing column is connected with a lower fixing column. Connecting columns are arranged around the bottom end of the lower fixing column. An installation opening is provided at the top end of the upper fixing column. A connection opening is provided on the side of the connecting column away from the lower fixing column. The upper fixing column and the lower fixing column are connected by fixing bolts. This scheme can improve the overall convenience, adjustability and practicability of the docking structure of the prefabricated light steel building. However, when the above technical scheme is actually used, there are still the following deficiencies:

[0004] In the above scheme and most other existing technologies, the position of the docking groove of the docking structure is pre-designed on the component. This design depends on the detailed planning and accurate calculation of the building structure in the early stage to ensure that the angle during the installation of the light steel matches the position of the docking groove. However, this fixed design lacks flexibility, restricts the versatility and adaptability of the docking structure. The design requirements of the fixed docking groove must consider all possible assembly conditions at the design stage, which greatly increases the complexity and uncertainty of the design. At the same time, it also brings higher precision requirements to the construction team, increases the construction difficulty and potential error rate. Once the light steel component is fixed through the docking groove, its direction and angle are locked and cannot be fine-tuned or changed subsequently. This means that all possible deviations and changes must be accurately predicted at the design stage. Otherwise, if the angle or direction is not ideal after installation, it is very difficult to correct. Once the preset position of the light steel component does not match the actual need, it may be necessary to disassemble and reinstall, which not only consumes more manpower and time, but also may affect the progress of the entire project. When facing complex building space layouts, such as curved buildings, multi-angle intersections or scenarios that require three-dimensional space adjustment, the fixed docking groove design often fails to meet the requirements because these scenarios require the components to be able to freely adjust the angle in multiple directions, while the docking structures in the existing technologies often cannot provide this level of flexibility.

[0005] Therefore, it is necessary to design a docking structure for prefabricated light steel buildings to solve the above problems. Summary of the Invention

A rotatable connecting ball is provided among all the slots, and the surface of the connecting ball is adapted to the inner side of the slot. A fixing component for fixing the connecting ball is provided on the fixed block.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Refer to Figures 1-3 , a docking structure of a prefabricated light steel building, including a docking block 1. The docking block 1 has a cube structure. A fixing block 2 is fixedly connected to each surface of the docking block 1. A plurality of connecting blocks 3 are provided on the side of the fixing block 2 away from the docking block 1. A slot 4 is provided inside the connecting block 3. A rotatable connecting ball 5 is provided among all the slots 4, and the surface of the connecting ball 5 is adapted to the inner side of the slot 4. The connecting blocks 3 are arranged at equal intervals in the circumferential direction, which enables the force exerted by the slots 4 on the connecting ball 5 to be evenly distributed. Scale lines are provided on the side wall of the connecting ball 5 to facilitate workers to adjust the direction and angle of the connecting ball 5 according to the scale lines. A fixing component for fixing the connecting ball 5 is provided on the fixing block 2.

[0023] Refer to Figure 1 and Figure 3, the fixing component includes a plurality of fixing plates 6 fixedly connected to the side of the fixing block 2 away from the docking block 1. All the fixing plates 6 are respectively fixed to all the connecting blocks 3. Both ends of the fixing plate 6 are respectively located at the edge positions of the side walls of the fixing block 2 and the connecting block 3. The fixing block 2 has a cylindrical structure, and the fixing block 2 is coaxial with the center of the connecting ball 5. A sleeve 7 is threadedly sleeved on the fixing block 2. Both the connecting block 3 and the fixing plate 6 are threadedly connected to the inner side of the sleeve 7. The fixing plate 6 is slightly inclined outward in the non-loaded state. At this time, the connecting ball 5 can rotate freely in the slot 4. When the sleeve 7 is threadedly connected to the fixing plate 6 and the connecting block 3, under the limiting and pressing action of the sleeve 7, the fixing plate 6 can gather toward the connecting ball 5, so that the connecting block 3 can press the connecting ball 5 to fix the connecting ball 5. Anti-slip and wear-resistant layers 14 are provided on the inner side of the slot 4 and the surface of the connecting ball 5, which can increase the friction between the slot 4 and the connecting ball 5 and ensure the stability of the fixing of the connecting ball 5.

[0024] Refer to Figure 2 , a connecting component is provided on the connecting ball 5. The connecting component includes a slot 10 provided on the side wall of the connecting ball 5. An insertion block 8 is provided inside the slot 10. A docking groove 9 for docking light steel is provided on the side wall of the insertion block 8 away from the slot 10. The docking groove 9 is designed in a shape adapted to the commonly used light steel types on the market. A plurality of first threaded holes 11 are provided on the side wall of the insertion block 8. A plurality of second threaded holes 12 are provided on the side wall of the connecting ball 5. The positions of the first threaded holes 11 and the second threaded holes 12 correspond to each other. The insertion block 8 can be fixed inside the slot 10 by using bolts, realizing the replacement of the type of the docking groove 9. A fixing frame 13 is fixedly sleeved on one end of the side wall of the insertion block 8. The fixing frame 13 is located outside the slot 10, which facilitates the staff to take out the insertion block 8.

[0025] The specific working principle of the present utility model is as follows:

[0026] During assembly, the staff first adjust the angles of each connecting ball 5 on the docking block 1. There are scale lines on the connecting ball 5 to facilitate accurate adjustment by the staff. Subsequently, the sleeve 7 is rotated. The sleeve 7 will move while rotating away from the docking block 1. Then, the inner side of the sleeve 7 will sequentially squeeze the fixing plate 6 and the connecting block 3. One end of the fixing plate 6 connected to the fixed block 2 will undergo a slight deformation, enabling the connecting block 3 to move closer to the connecting ball 5. As a result, the inner side of the slot 4 squeezes the connecting ball 5. At this time, the sleeve 7 is threadedly connected to the fixed block 2, the connecting block 3, and the fixing plate 6 respectively, thus achieving the fixation of the connecting ball 5. Moreover, anti-slip and wear-resistant layers 14 are provided on both the inner side of the slot 4 and the surface of the connecting ball 5, further enhancing the stability of the fixation of the connecting ball 5. After fixing each connecting ball 5, one end of the light steel is inserted into the docking groove 9, and the other end of the light steel is also inserted into the docking groove 9 of another docking structure, thereby fixing the light steel. This docking structure can flexibly adjust the direction of the light steel and the angles in each direction, improving the flexibility and practicality of the device application. At the same time, it also reduces the labor intensity and improves the assembly efficiency of the light steel;

[0027] Furthermore, the types of light steel vary according to different usage scenarios. Generally, there are C-shaped steel, Z-shaped steel, H-shaped steel, etc. The shapes of the corresponding docking grooves 9 for different types of light steel are also different. When different types of light steel need to be assembled in combination, the bolts in the first threaded hole 11 and the second threaded hole 12 are removed, and the insertion block 8 can be taken out of the insertion slot 10 through the fixing frame 13, so that the required insertion block 8 can be replaced. This further improves the convenience and flexibility of the assembly.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
