Description

Technical Field

[0001] This utility model relates to the field of steel structure purlin technology, and in particular to a steel structure purlin with stable connection. Background Technology

[0002] In the field of modern construction engineering, steel structures have become one of the mainstream building forms due to their high strength, high toughness and ease of construction. As an important supporting component for roofs and walls, the connection quality of steel purlins directly affects the stability and safety of the overall building structure.

[0003] However, existing steel structure purlins are generally connected and fixed using welding. While welding can ensure the integrity and strength of the structure to a certain extent, it has many drawbacks. The permanent connection formed by welding makes it difficult to disassemble and replace monitoring devices. When the devices malfunction or need to be upgraded, the disassembly process often damages the main steel structure and may even compromise its mechanical properties, increasing repair costs and construction risks. In addition, the non-removable design also limits the reuse of purlins. Utility Model Content

[0004] To address the technical problem that existing steel structure purlins are generally connected and fixed by welding, which is inconvenient for disassembly, this utility model provides a steel structure purlin with stable connection.

[0005] The technical solution adopted by this utility model is as follows: A stable steel structure purlin includes a first horizontal bar, a second horizontal bar, a first connecting component, and a second connecting component. Multiple sets of fixing blocks are fixedly connected to the outside of the first horizontal bar. Multiple sets of first limiting frames are fixedly connected to the top of the first horizontal bar. The second horizontal bar passes through the first limiting frames. A second limiting frame is sleeved on the outside of the second horizontal bar. A first connecting rod is provided on the outside of the second limiting frame. A second connecting rod is rotatably connected to the outside of the first connecting rod. The first connecting rod is detachably connected to the second limiting frame and the fixing blocks through the first connecting component. The second connecting rod is detachably connected to the first limiting frame through the second connecting component.

[0006] The present invention is further configured such that the first connecting component includes a first threaded post and a third threaded post, the first threaded post passes through the first connecting rod and the second limiting frame, the outside of the first threaded post is threadedly connected with a first threaded sleeve, the third threaded post passes through the first connecting rod and the fixing block, and the two ends of the third threaded post are threadedly connected with a third threaded sleeve.

[0007] The present invention is further configured such that the second connecting component is a second threaded post, the second threaded post passing through the second connecting rod, the first limiting frame and the second crossbar, and both ends of the second threaded post are threadedly connected to a second threaded sleeve.

[0008] A further feature of this invention is that both the first horizontal bar and the second horizontal bar are I-shaped structures.

[0009] A further feature of this invention is that rubber pads are fixedly connected to the inner walls of both the first limiting frame and the second limiting frame.

[0010] A further feature of this invention is that the second horizontal bar has at least one set.

[0011] A further feature of this invention is that the first horizontal bar and the second horizontal bar form a cross-shaped structure.

[0012] The beneficial effects of this utility model are as follows: In this utility model, the fixing block and the first limiting frame on the first horizontal bar, as well as the second limiting frame outside the second horizontal bar, together constitute a precise positioning and support system. The first connecting rod and the second connecting rod, together with the first and second connecting components, realize a detachable connection between the first and second horizontal bars. This design facilitates quick and accurate installation and adjustment by construction workers during the building construction process, significantly improving construction efficiency compared to traditional welding or non-detachable connection methods.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0022] To address the problems existing in the background art, this application proposes the following technical solution: a stable steel structure purlin, including a first horizontal bar 1, a second horizontal bar 2, a first connecting component, and a second connecting component. Both the first horizontal bar 1 and the second horizontal bar 2 are I-shaped structures. At least one set of the second horizontal bar 2 is provided. The first horizontal bar 1 and the second horizontal bar 2 form a cross-shaped structure. Multiple sets of fixing blocks 3 are fixedly connected to the outside of the first horizontal bar 1. Multiple sets of first limiting frames 4 are fixedly connected to the top of the first horizontal bar 1. The second horizontal bar 2 passes through the first limiting frames 4, and a second limiting frame is fitted around the outside of the second horizontal bar 2. 5. Rubber pads are fixedly connected to the inner walls of both the first limiting frame 4 and the second limiting frame 5. A first connecting rod 6 is provided on the outside of the second limiting frame 5. A second connecting rod 8 is rotatably connected to the outside of the first connecting rod 6 via a pin 9. The first connecting rod 6 is detachably connected to the second limiting frame 5 and the fixing block 3 via a first connecting assembly. The second connecting rod 8 is detachably connected to the first limiting frame 4 via a second connecting assembly. In this scheme, the first horizontal bar 1 and the second horizontal bar 2 adopt an I-shaped structure. This classic mechanical design can effectively reduce its own weight and improve material utilization while ensuring material strength. Multiple sets of second horizontal bars 2 and first horizontal bars 1 form a cross-shaped structure, which greatly enhances the overall spatial stability and load-bearing capacity of the steel structure purlin and can better distribute the load transmitted from the building roof, etc. The fixing block 3 and the first limiting frame 4 on the first horizontal bar 1, as well as the second limiting frame 5 on the outside of the second horizontal bar 2, together constitute a precise positioning and support system. The rubber pads on the inner wall of the limiting frame serve a dual purpose of cushioning and anti-slip, not only reducing hard friction between the first horizontal bar 1 and the second horizontal bar 2 to prevent structural damage, but also further improving the stability of the connection by increasing friction. The first connecting rod 6 and the second connecting rod 8, together with the first and second connecting components, achieve a detachable connection between the first horizontal bar 1 and the second horizontal bar 2. This design facilitates quick and accurate installation and adjustment by construction workers during building construction, significantly improving construction efficiency compared to traditional welding or non-detachable connection methods.

[0023] In this embodiment, the first connecting assembly includes a first threaded post 7 and a third threaded post 11. The first threaded post 7 passes through the first connecting rod 6 and the second limiting frame 5. A first threaded sleeve 12 is threadedly connected to the outside of the first threaded post 7. The third threaded post 11 passes through the first connecting rod 6 and the fixing block 3. Third threaded sleeves 14 are threadedly connected to both ends of the third threaded post 11. The design of the first connecting assembly fully utilizes the fastening characteristics of threaded connections, providing a reliable guarantee for the connection between the first horizontal bar 1 and the second horizontal bar 2. After the first threaded post 7 passes through the first connecting rod 6 and the second limiting frame 5, it is fastened by the first threaded sleeves 12 at both ends. This method can tightly connect the first connecting rod 6 and the second limiting frame 5 together, allowing the second limiting frame 5 to be securely fitted onto the outside of the second horizontal bar 2, thereby providing lateral restraint to the second horizontal bar 2 and effectively preventing horizontal displacement or swaying of the second horizontal bar 2 during use. The third threaded post 11 passes through the first connecting rod 6 and the fixing block 3, and is fixed by the third threaded sleeves 14 at both ends, firmly connecting the first connecting rod 6 to the fixing block 3 on the first horizontal bar 1. This allows the first connecting rod 6 to work in coordination with the first horizontal bar 1 when transmitting loads, enhancing the load-bearing capacity of the entire connection structure in both vertical and horizontal directions.

[0024] In this embodiment, the second connecting component is a second threaded post 10, which passes through the second connecting rod 8, the first limiting frame 4, and the second horizontal bar 2. Both ends of the second threaded post 10 are threaded with second threaded sleeves 13. With the second threaded post 10 as its core, the second connecting component, through its cooperation with the second threaded sleeves 13, achieves a stable connection between the second connecting rod 8, the first limiting frame 4, and the second horizontal bar 2, further enhancing the stability of the cross-shaped connection node between the first horizontal bar 1 and the second horizontal bar 2. After the second threaded post 10 passes through the second connecting rod 8, the first limiting frame 4, and the second horizontal bar 2, tightening the second threaded sleeves 13 at both ends secures these three components together, forming a rigid whole. This connection method allows the second connecting rod 8 to effectively transfer the load to the first limiting frame 4 and the second horizontal bar 2, while restricting the movement of the second horizontal bar 2 in both the vertical and horizontal directions, ensuring that the connection node does not loosen or deform when the purlin is subjected to various loads (such as roof loads, wind loads, etc.). Compared to traditional riveting and welding methods, threaded connections for the second connection component offer significant advantages. During installation, complex welding operations are eliminated, avoiding the impact of high welding temperatures on steel properties and reducing quality issues such as welding deformation, thus ensuring the installation accuracy and quality of the steel structure purlins.

[0025] The usage method of this embodiment is as follows:

[0026] Pass the second horizontal bar 2 through the first limiting frame 4, then take the first threaded post 7, the second threaded post 10 and the third threaded post 11, pass the first threaded post 7 through the second limiting frame 5, pass the second threaded post 10 through the first limiting frame 4 and the second horizontal bar 2, and pass the third threaded post 11 through the fixing block 3. Then thread the two ends of the first threaded post 7 to the first threaded sleeve 12, thread the two ends of the second threaded post 10 to the second threaded sleeve 13, and thread the two ends of the third threaded post 11 to the third threaded sleeve 14. The second horizontal bar 2 can then be securely installed on the outside of the first horizontal bar 1.

[0027] During disassembly, simply remove the first threaded sleeve 12, the second threaded sleeve 13, and the third threaded sleeve 14, then pull out the first threaded post 7, the second threaded post 10, and the third threaded post 11, and finally pull out the second horizontal bar 2.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
