Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a steel structure component connection structure. Background Technology

[0002] In the field of steel structure construction, the connection structure of steel structural components is a key element in ensuring the stability and safety of the entire building structure. Steel structures, with their high strength, lightweight, and excellent seismic performance, are widely used in modern architecture. The connections between steel structural components are like joints in the human body, tightly linking individual components together to form an organic whole that collectively bears various loads and effects. A reliable connection structure not only ensures the stability of the steel structure during normal use but also effectively transfers and disperses stress in extreme situations such as earthquakes and windstorms, preventing structural damage and thus protecting people's lives and property. Therefore, developing an efficient, stable, and flexible connection structure for steel structural components is of significant practical importance.

[0003] However, traditional steel structure component connection technologies have many drawbacks, seriously affecting the quality and construction efficiency of steel structure buildings. Traditional connection methods, such as welding, while achieving component connection to a certain extent, each have significant limitations. Although welding provides high connection strength, the high temperatures generated during welding can easily alter the steel's material composition, affecting structural performance. Furthermore, welding quality is greatly influenced by the welder's skill level and environmental factors, easily leading to welding defects such as porosity and slag inclusions. These defects reduce connection reliability and can even cause safety accidents. In addition, traditional connection structures lack sufficient flexibility and adaptability when dealing with complex and ever-changing connection requirements, often requiring customized connectors, increasing project costs and construction difficulty. Therefore, there is an urgent need for a new type of steel structure component connection structure to overcome the shortcomings of traditional technologies. To this end, we propose a steel structure component connection structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a steel structure component connection structure that solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a steel structure component connection structure, including a fixing plate, wherein four equally spaced grooves are provided at the bottom of the inner wall of the fixing plate, the grooves have a T-shaped cross-section, and a support rod body is provided at the bottom of the inner wall of the groove. The outer wall of one end of the support rod body is engaged with one end of the inner wall of the groove, and the outer wall of the end of the support rod body that contacts the groove is T-shaped.

[0006] Preferably, the outer wall of the support rod body away from the slot is provided with a threaded post, and the top of the fixing plate is threadedly connected with a locking cover, the bottom of the locking cover being tightly pressed against the outer wall of one end of the support rod body.

[0007] Preferably, the output end of the threaded column away from the main body of the support rod is provided with a connecting sleeve, and the inner wall of one end of the connecting sleeve is threadedly connected to the threaded column.

[0008] Preferably, the output end of the connecting sleeve away from the threaded post is provided with an extension rod, and the outer wall of the extension rod near the connecting sleeve is provided with a second threaded post, and the second threaded post is threadedly connected to the inner wall of the connecting sleeve away from the threaded post.

[0009] Preferably, the extension rod has a third threaded post on the outer wall of the end away from the second threaded post, and a fixing head is provided on the outer wall of the third threaded post. The fixing head and the third threaded post are threadedly connected.

[0010] Preferably, the outer wall of one end of the fixing head has four fixing holes that are equally spaced in a rectangle.

[0011] Preferably, the extension can be extended at will by connecting multiple connecting sleeves and extension rods.

[0012] Compared with the prior art, the present invention provides a steel structure component connection structure, which has the following beneficial effects:

[0013] 1. Compared to traditional steel structure component connection technologies, such as common welding and bolting, this steel structure component connection structure exhibits superior flexibility and scalability. Traditional welded connections, once completed, have essentially fixed lengths and angles, making adjustments difficult to meet actual needs. While bolted connections are relatively flexible, they often require custom-made connectors to handle significant length changes or special angle connections, increasing cost and construction difficulty. This device, through its unique design and threaded connection between the connecting sleeve and extension rod, easily allows for arbitrary extension of the connection structure, enabling precise adjustment of the connection length according to different engineering scenarios. Simultaneously, the ingenious cooperation between the components allows for flexible adjustment of the connection angle, perfectly adapting to various complex and changing connection requirements. This significantly improves the versatility and adaptability of steel structure component connections, effectively reducing engineering changes and cost increases caused by connection mismatches.

[0014] 2. Compared to traditional steel structure connection technologies, this steel structure component connection structure has certain shortcomings in terms of connection stability. Welded connections are prone to changes in steel material properties under high temperatures, and welding defects such as porosity and slag inclusions significantly reduce connection reliability and increase safety hazards. Bolted connections, due to their lower rigidity at the connection points, are prone to loosening and deformation under stress, affecting the overall stability of the structure. This steel structure component connection structure effectively overcomes these problems through the synergistic effect of multiple components. The snap-fit ​​between the fixing plate and the main body of the strut, as well as the tight pressing between the locking cover and the main body of the strut, form a stable foundation support; the threaded connections between the threaded column, connecting sleeve, extension rod, and fixing head further enhance the tightness and stability of the connection. This multi-layered stable connection design enables the device to withstand greater loads and actions, effectively transfer and disperse stress, provide reliable protection for the safety of steel structure buildings, and greatly reduce the risk of safety accidents caused by connection problems.

[0015] 3. The steel structure component connection structure adopts a simple and efficient connection method. The threaded connections between the components make the installation and disassembly process easy and quick. Construction personnel can quickly complete the installation and disassembly of the connection structure without complex operating skills or a lot of time. This not only shortens the construction cycle and reduces labor costs, but also improves the work efficiency on the construction site, enabling the steel structure building to be put into use more quickly and providing strong support for the smooth progress of the project.

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.

[0021] Please see Figure 1-3A steel structure component connection structure includes a fixed plate 1. The bottom of the inner wall of the fixed plate 1 has four equally spaced grooves 2 arranged in a ring. The grooves 2 have a T-shaped cross-section. The bottom of the inner wall of the grooves 2 has a support rod body 3. One end of the outer wall of the support rod body 3 is engaged with one end of the inner wall of the groove 2. The outer wall of the end of the support rod body 3 that contacts the groove 2 is T-shaped. This T-shaped engagement design allows the support rod body 3 to be stably installed in the grooves 2 of the fixed plate 1, preventing the support rod body 3 from shifting in the horizontal direction and providing a stable foundation support for the subsequent connection structure.

[0022] Furthermore, the outer wall of the support rod body 3 away from the slot 2 is provided with a threaded post 4, and the top of the fixing plate 1 is threadedly connected with a locking cover 5. The bottom of the locking cover 5 is tightly pressed against the outer wall of one end of the support rod body 3. The tight pressing between the locking cover 5 and the support rod body 3, as well as the threaded connection between the locking cover 5 and the fixing plate 1, further enhances the stability of the support rod body 3 on the fixing plate 1, prevents the support rod body 3 from loosening or falling out in the vertical direction, and improves the reliability of the entire connection structure.

[0023] Furthermore, a connecting sleeve 6 is provided at the output end of the threaded column 4 away from the main body 3. The inner wall of one end of the connecting sleeve 6 is threadedly connected to the threaded column 4. The threaded connection between the connecting sleeve 6 and the threaded column 4 allows the connecting sleeve 6 to be easily installed on the threaded column 4, increasing the flexibility and adjustability of the connection structure.

[0024] Furthermore, the output end of the connecting sleeve 6 away from the threaded post 4 is provided with an extension rod 7, and the outer wall of the extension rod 7 near the connecting sleeve 6 is provided with a second threaded post 8. The second threaded post 8 is threadedly connected to the inner wall of the connecting sleeve 6 away from the threaded post 4. The threaded connection between the extension rod 7 and the connecting sleeve 6 allows the extension rod 7 to be easily installed on the connecting sleeve 6. By increasing the length of the extension rod 7, the connection structure can be extended to adapt to different length connection requirements, thereby improving the versatility and applicability of the connection structure.

[0025] Furthermore, a third threaded post 9 is provided on the outer wall of the end of the extension rod 7 away from the second threaded post 8, and a fixing head 10 is provided on the outer wall of the third threaded post 9. The fixing head 10 and the third threaded post 9 are threadedly connected. The threaded connection between the fixing head 10 and the third threaded post 9 allows the fixing head 10 to be easily installed on the extension rod 7. The design of the fixing head 10 enables the connection structure to be firmly connected with other steel structure components, thereby improving the connection strength and stability of the connection structure.

[0026] Furthermore, four rectangularly equidistant fixing holes 11 are provided on the outer wall of one end of the fixing head 10. The design of the fixing holes 11 allows the fixing head 10 to be connected to other steel structure components by fasteners such as bolts. This connection method is simple and reliable, and is easy to install and disassemble. At the same time, the four rectangularly equidistant fixing holes 11 also improve the stability and load-bearing capacity of the connection.

[0027] Furthermore, the connection can be extended at will by connecting multiple connecting sleeves 6 and extension rods 7. This design allows the connection structure to be flexibly adjusted in length according to actual needs without replacing the entire connection structure, which reduces costs and improves efficiency. The connection of multiple connecting sleeves 6 and extension rods 7 also increases the complexity and stability of the connection structure, enabling it to better adapt to various complex connection requirements.

[0040] Working Principle: Initial stable connection is achieved through the linkage of the fixed plate 1, the slots 2, and the support rod body 3. The bottom inner wall of the fixed plate 1 has four T-shaped slots 2 arranged in a ring at equal intervals. One end of the support rod body 3 has a T-shaped outer wall that engages with one end of the slot 2. This engagement method allows the support rod body 3 to be securely installed on the fixed plate 1, initially ensuring the stability of the connection structure and providing basic support for the installation of subsequent components. The linkage of the support rod body 3, the threaded post 4, and the locking cover 5 further enhances the stability of the connection. The outer wall of the support rod body 3, away from the slots 2, has a threaded post 4. The top of the fixed plate 1 is threaded with a locking cover 5, and the bottom of the locking cover 5 is tightly pressed against the outer wall of one end of the support rod body 3. When the locking cover 5 is tightened onto the fixing plate 1, it applies downward pressure to the support rod body 3, making the engagement between the support rod body 3 and the slot 2 tighter. This effectively prevents the support rod body 3 from loosening or shifting under stress, further improving the stability of the connection structure. Through the linkage of the threaded post 4, connecting sleeve 6, extension rod 7, second threaded post 8, third threaded post 9, and fixing head 10, flexible length adjustment and a secure terminal connection are achieved. The threaded post 4 has a connecting sleeve 6 at its output end away from the support rod body 3, and the inner wall of one end of the connecting sleeve 6 is threadedly connected to the threaded post 4. The connecting sleeve 6 has an extension rod 7 at its output end away from the threaded post 4, and the extension rod 7 has a second threaded post 8 at its outer wall near the connecting sleeve 6, which is threadedly connected to the inner wall of the connecting sleeve 6 at its outer wall away from the threaded post 4. The extension rod 7 has a third threaded post 9 at its outer wall away from the second threaded post 8, and the fixing head 10 is threadedly connected to the third threaded post 9 at its outer wall. This multi-stage threaded connection method allows the connection structure to be extended arbitrarily by connecting multiple connecting sleeves 6 and extension rods 7 to adapt to different length connection requirements. At the same time, four rectangularly spaced fixing holes 11 are opened on the outer wall of one end of the fixing head 10, which can be firmly connected to other steel structure components by bolts or other fasteners, thereby completing the terminal connection of the entire connection structure.
