Description

Technical Field

[0001] The utility model relates to the technical field of secondary purlins, in particular to a fastened, welding-free compartment secondary purlin. Background Art

[0002] Secondary purlins are an integral part of the roofing system. Structurally, they are typically slender members. They are typically located below the main purlins in the roofing system, connected to them through a specific connection method. They transfer the loads borne by the roof decking or other roof covering materials to the main purlins, which then transfer them to the main structure (such as steel beams and columns). This provides support for the roof decking and ensures its stability and flatness during use.

[0003] The connection between the secondary purlins and the main purlins is usually connected together by welding. However, over time, if the residual stress is not effectively eliminated after welding, the residual stress may cause tiny cracks to appear near the welds of the secondary purlins over time. Then, under the action of load, the cracks gradually expand, reducing the bearing capacity of the secondary purlins. In addition, when the position of the spacer needs to be adjusted, the welds need to be cut during dismantling, which greatly increases the cost of dismantling. It is not only time-consuming and labor-intensive, but may also cause damage to the main purlins or other connecting parts. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the secondary purlin is difficult to adjust after welding, which may easily cause the connection parts to be damaged. The utility model provides a fastened and weld-free compartment secondary purlin.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1:

[0021] like Figure 1-Figure 4 As shown, a fastened, weld-free compartment purlin comprises a main frame 1, the top of the main frame 1 is fixedly connected with a side panel 1 2 and a side panel 2 3, the side panel 1 2 and the side panel 2 3 are respectively located at the left and right ends of the top side of the main frame 1, the main frame 1 comprises a bottom plate 11 and a grooved plate 12, the grooved plate 12 is arranged between the gaps of the bottom plate 11, the side walls of the main frame 1, the side panel 1 2 and the side panel 2 3 are all provided with mounting holes 4, the mounting holes 4 are used to insert screws and connect with other structures during installation, reinforcing ribs 5 are horizontally penetrated at the side panels 1 2 and the side panels 2 3, connecting holes 7 are provided at the side walls of the side panels 1 2 and the side panels 2 3, the side walls of the reinforcing ribs 5 penetrate the connecting holes 7, outer edge areas 6 are provided on the front and rear sides of the main frame 1, a textured area 8 is provided on the side walls of the main frame 1, and an anti-corrosion coating 9 is coated on the outer side walls of the main frame 1.

[0022] like Figure 1-Figure 3 As shown, the outer edge area 6 is provided at the front and rear sides of the bottom plate 11, and the front and rear ends of the grooved plate 12 are wrapped around the side ends of the outer edge area 6. This arrangement of the outer edge area 6 greatly enhances the structural strength and stability of the side of the bottom plate 11. When the partition frame is impacted by external forces, the outer edge area 6 can effectively disperse and withstand these forces, reducing direct damage to the bottom plate 11, thereby extending the service life of the bottom plate 11.

[0023] like Figure 1-Figure 3As shown, the bottom sides of the side panels 1 2 and 2 3 are fixedly connected to the front and rear sides of the bottom plate 11 and the grooved plate 12. The outer edges of the bottom sides of the side panels 1 2 and 2 3 are located at the inner ends of the outer edge area 6. High-strength metal materials are used to provide support and load-bearing capacity. In actual applications, when the partition frame is subjected to forces from different directions, such as vertical gravity or horizontal wind force, this stable connection can effectively disperse and transmit the force, avoiding structural damage caused by local force concentration.

[0024] like Figure 1-Figure 2 As shown, the mounting holes 4 and the connecting holes 7 provided on the side walls of the side panels 1 2 and 2 3 are symmetrically positioned, which facilitates the reinforcement ribs 5 to support the side walls of the side panels 1 2 and 2 3 together;

[0025] like Figure 1-Figure 3 As shown, a trapezoidal groove is provided on the outer side of the outer edge region 6. The presence of the trapezoidal groove increases the surface area of ​​the outer edge region 6, thereby improving the friction and bite force when it contacts the external structure or component. In practical applications, when the secondary purlin needs to be tightly combined with other structures, this increased friction can effectively prevent relative sliding, ensuring the stability and safety of the entire structure. Example 2:

[0026] like Figure 1 and Figure 3 As shown, a textured area 8 is provided on the side wall of the bottom plate 11. The design of the textured area 8 first increases the friction of the side wall of the bottom plate 11. When in contact or interacting with other components, it can effectively prevent sliding and enhance the stability of the connection. At the same time, the presence of the texture helps to disperse stress, so that under stress, the stress can be more evenly distributed on the side wall of the bottom plate 11, reducing the risk of damage caused by local stress concentration. The inner side of the side panel 1 2 and the side panel 2 3 are both provided with a textured area 8, which increases the friction between the side panel and the internal filler or other components, and improves the compactness and stability of the overall structure. On the other hand, when the side panel is subjected to forces from different directions, the textured area can play a role in buffering and dispersing stress, thereby enhancing the side panel's ability to resist deformation and damage.

[0027] like Figure 1 and Figure 4 As shown, the outer sides of the side panels 1 2 and 3 are equivalent to the outer sides of the main frame 1 and are coated with an anti-corrosion coating 9, which provides a solid protective barrier for these components and can effectively block the intrusion of external moisture, oxygen, chemicals and various corrosive media. In harsh environmental conditions, such as high humidity, high salinity or places with chemical pollution, this coating can significantly delay the oxidation and corrosion process of the metal, thereby greatly extending the service life of the secondary purlin.
