Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a connection structure for steel structure components. Background Art

[0002] The connection structure of steel structure components refers to the structural form in which different components in the steel structure are connected to each other through certain methods and components to achieve overall structural splicing, force transmission and load-bearing. This connection structure is a crucial link in steel structure engineering, and its quality and reliability directly affect the safety and stability of the entire structure.

[0003] The scissors brace connection structure refers to connecting multiple scissors braces through specific connection methods and connectors to form a more complex and stable support structure. The scissors brace usually refers to those support structures that use two struts that are forked and then intersected, which are commonly found in building scaffolding.

[0004] The patent with publication number CN216476291U discloses a scissors-strut universal connector, including a base plate and a fixed rod arranged on the surface of the base plate. The fixed rods include four and are distributed in a rectangular shape. Each fixed rod is provided with a detachable universal rotating rod. One end of the universal rotating rod is rotatably connected to the fixed rod, and the other end is connected to the scissors-strut steel pipe by a thread. Although the above device solves the problem that the middle part of the traditional scissors-strut steel pipe is not connected to the frame.

[0005] However, the above technical solution still has the following problems:

[0006] The weakness of the middle connection of the scissors brace will greatly reduce the bearing capacity of the entire scissors brace structure. When subjected to external force, the weak point is likely to become a key area of ​​stress concentration, which is prone to fracture or failure. Moreover, since the struts cannot be adjusted, this weakness cannot be effectively compensated or corrected, thereby increasing the risk of structural failure. The inability to adjust the struts also limits the flexibility and adaptability of the scissors brace structure during use. In actual applications, due to construction errors, differences in material properties or changes in external conditions, the length or angle of the struts may need to be adjusted. However, if the struts cannot be adjusted, they will not be able to respond effectively to these changes, resulting in a decrease in structural performance or failure to meet design requirements. Utility Model Content

[0007] In view of the deficiencies of the prior art, the utility model provides a connection structure for steel structure members to at least solve one of the problems raised by the background technology, such as: enhancing the stability and safety of the connection structure, and improving the convenience of installation and maintenance.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a connection structure for steel structure members, including a strut body, the strut body including a cross fixing block, a support rod and a connecting column, one end of the cross fixing block is connected to a support rod, the number of support rods is greater than 1, and the lengths of the multiple support rods are different, connecting columns are installed between the multiple support rods, and a plug-in rod is provided at one end of the connecting column near the tail of the strut body, and a welding plate is provided at the other end of the plug-in rod.

[0009] Furthermore, a threaded column a is fixedly connected to the end of the cross fixing block, and threaded grooves a which are threadedly connected to the outer side of the threaded column a are provided at both ends of the support rod.

[0010] Furthermore, both ends of the connection column are fixedly connected with threaded columns b, and the outer side of the threaded column b is threadedly connected to the inner wall of the thread groove a.

[0011] Furthermore, one end of the plug-in rod is provided with a thread groove b which is threadably connected to the outer side of the thread column b.

[0012] Furthermore, the thread directions of the thread column a, the thread column b, the thread groove a and the thread groove b are consistent.

[0013] Furthermore, one end of the welding plate is fixedly connected with a connecting shell, the connecting shell and one end of the plug-in rod are inserted and connected, and the inner wall of the connecting shell and the outer side of one end of the plug-in rod are fitted and connected.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model designs the middle connecting piece of the scissors brace as an integrated piece, so that the middle connection can effectively reduce the risk of loosening and falling off of the connecting piece, thereby enhancing the stability and safety of the entire scissors brace structure. The design that the length of the strut can be adjusted makes the scissors brace structure more flexible and changeable, and can be adjusted according to different engineering requirements, and can adapt to different construction environments and structural forms, thereby improving the applicability of the scissors brace; at the same time, the adjustment of the length of the strut can also optimize the force distribution of the structure, and improve the bearing capacity and stability of the structure.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] like Figures 1 to 5 As shown, a connection structure for steel structure members includes a strut body 1, the strut body 1 includes a cross fixing block 2, a support rod 3 and a connecting column 4, one end of the cross fixing block 2 is connected to the support rod 3, the number of support rods 3 is greater than 1, and the lengths of the plurality of support rods 3 are different, connecting columns 4 are installed between the plurality of support rods 3, one end of the connecting column 4 near the tail of the strut body 1 is provided with a plug-in rod 5, and the other end of the plug-in rod 5 is provided with a welding plate 6.

[0024] like Figure 1 As shown, a connection structure for steel structure members in the utility model is similar to the existing scissors brace connection structure, such as the scissors brace universal connector disclosed in the patent publication number CN216476291U. The main improvement of the utility model is to make the scissors brace structure adapt to different construction environments and structural forms, and improve the applicability of the scissors brace, such as Figures 1 to 5 As shown, when a steel structure component connection structure in the utility model is in use, the support rod body 1 is the core of the entire connection structure, transmitting and dispersing the load, the cross fixing block 2 is located at one end of the support rod body 1, and it plays a role of fixing and supporting to ensure the stability of the entire connection structure, the support rod 3 provides support in different directions to enhance the overall stability of the structure, and multiple support rods 3 are interconnected by connecting columns 4 to form a stable support system. The connecting column 4 not only plays the role of connecting the support rods 3, but also increases the overall rigidity and strength of the structure. The welding plate 6 is connected to the steel structure component by welding, so that the steel structure component and the support rod body 1 form a whole, and the plug-in method of the splicing rod 5 and the welding plate 6 is convenient for fine-tuning at the construction site to ensure the accuracy and precision of the connection.

[0025] like Figures 2 to 3 As shown, a threaded column a201 is fixedly connected to the end of the cross fixing block 2, and threaded grooves a301 threadedly connected to the outer side of the threaded column a201 are formed at both ends of the support rod 3.

[0026] Specifically, through this arrangement, by rotating the support rod 3, the threaded grooves a301 at both ends thereof can be closely matched with the threaded columns a201, thereby achieving a firm connection between the support rod 3 and the cross fixing block 2. This connection method is suitable for support rods 3 of different lengths, making the connection structure more flexible. The threaded connection also has a self-locking function, which can effectively prevent the connection from loosening or falling off, thereby improving the safety and stability of the connection structure. At the same time, this connection method is also convenient for maintenance and replacement of parts, reducing maintenance costs and time.

[0027] like Figure 3 to Figure 4 As shown, threaded columns b401 are fixedly connected at both ends of the connecting column 4, and the outer side of the threaded column b401 is threadedly connected to the inner wall of the thread groove a301.

[0028] Specifically, by setting the threads on the outer side of the threaded column b401 to match the threads on the inner wall of the threaded groove a301, by rotating the connecting column 4, the threaded columns b401 at both ends can be tightly matched with the threaded groove a301 on the support rod 3 to achieve a firm connection.

[0029] like Figures 4 to 5 As shown, one end of the plug rod 5 is provided with a thread groove b501 which is threadably connected to the outer side of the thread column b401.

[0030] Specifically, by setting the thread groove b501 in this way, the plug-in rod 5 can be tightly matched with the thread column b401 by rotation, providing a simple, stable and reliable connection method for the steel structure component connection structure.

[0031] like Figures 2 to 5 As shown, the thread directions of the thread column a201, the thread column b401, the thread groove a301 and the thread groove b501 are consistent.

[0032] Specifically, this setting ensures the smooth connection between the various components and the stability of the overall structure. All components can be assembled in the same rotation direction, which not only simplifies the installation steps and improves work efficiency, but also reduces the possibility of errors during the installation process. At the same time, consistent thread direction also helps to ensure the tightness and reliability of the connection and prevent loosening or falling off due to thread mismatch.

[0033] like Figure 5 As shown, one end of the welding plate 6 is fixedly connected to a connecting shell 7, the connecting shell 7 and one end of the plug-in rod 5 are inserted and connected, and the inner wall of the connecting shell 7 and the outer side of one end of the plug-in rod 5 are fitted and connected.

[0034] Specifically, through this setting, the inner wall of the connecting shell 7 is tightly fitted with the outer side of one end of the plug-in rod 5. This fitting connection effectively prevents looseness and gaps at the connection, thereby improving the stability and reliability of the connection, allowing the plug-in rod 5 to be more smoothly inserted into the connecting shell 7, further simplifying the installation process. Welding, as a high-strength and high-reliability connection method, can firmly connect the welding plate 6 and the support rod body 1 together to form a whole. This connection method not only improves the strength of the connection, but also helps to disperse the force, making the entire connection structure more stable.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
