[0023] In this utility model, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. However, the phrase "direct connection" indicates that the two connected entities are not connected through an intermediate structure, but are connected to form a whole through a transmission structure. Those skilled in the art can understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0024] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0025] See also Figures 1 to 4 The utility model provides a technical solution: a torsion-resistant purlin, comprising a purlin 1, wherein the purlin 1 comprises a metal purlin 2 and a reinforcement structure 3, the surface of the metal purlin 2 being installed with the reinforcement structure 3; reinforcing right-angle ribs 7, which are fixed to the surfaces on both sides of the metal purlin 2, and play a reinforcing role on the metal purlin 2 in the reinforcement structure 3; reinforcing ribs 9, which are fixed in hollow grooves 8 opened on the surface of the metal purlin 2, and strengthen the structural strength of the metal purlin 2 in the reinforcement structure 3; the purlin 1 is a double-layer structure, which ensures lightweight while ensuring structural strength, and the built-in reinforcement structure 3 can ensure the torsion resistance of the metal purlin 2 at the bending part;

[0026] The metal purlin 2 includes an upper purlin 4, a lower purlin 5 and an oblique cut 6. The bottom end of the upper purlin 4 is fixedly connected to the lower purlin 5. The upper purlin 4 and the lower purlin 5 are staggered. Both ends of the upper purlin 4 and the lower purlin 5 are provided with an oblique cut 6.

[0027] The purlin 1 can be welded and spliced horizontally through the bevel cuts 6 opened at both ends;

[0028] The upper purlin 4 is made of light stainless steel and coated with anti-rust oil, and the lower purlin 5 is made of hard carbon steel;

[0029] The metal purlins 2 can be welded and spliced according to the length of the house. Unlike the previous vertical splicing, the metal purlins 2 are more firmly spliced using bevel cuts 6. The inclined design of the welds makes them less likely to break. The lower purlins 5 on the inside are harder and can withstand greater pressure when welded to the roof trusses. The upper purlins 4 on the outside have fewer stress-bearing surfaces, and the lightweight design can reduce the overall downward pressure.

[0030] The reinforcement structure 3 includes a reinforcement right-angle rib 7, a hollow groove 8 and a reinforcement rib 9. The reinforcement right-angle rib 7 is provided in several groups and is symmetrically arranged at the corners on both sides of the metal purlin 2. The surface of the metal purlin 2 is provided with a hollow groove 8. The hollow groove 8 is provided in several groups and is respectively arranged between two adjacent groups of reinforcement right-angle ribs 7. Each group of hollow grooves 8 is fixedly connected to an obliquely installed reinforcement rib 9.

[0031] The reinforcing right-angle ribs 7 are installed at the two bends of the metal purlin 2, which can reduce the compressive deformation of the metal purlin 2 and enhance the overall structural strength. The hollow groove 8 with a hollowed-out design in the middle is divided into two groups of triangles by the internal obliquely installed reinforcing ribs 9. The triangles are more stable and are less likely to be compressed and torsional deformed by the metal purlin 2, thereby enhancing the structural strength while ensuring a lightweight design.
