Detailed introduction
Purlins, also known as purlins and trusses, are horizontal roof beams perpendicular to roof trusses or rafters, which are used to support rafters or roofing materials. Purlins are transverse bending (usually bidirectional bending) members, which are generally designed as single-span simply supported purlins. There are two kinds of commonly used purlins: solid-web purlins and light steel trusses.
Purlin is a kind of material used to support building structures. It is usually made of wood or metal, featuring high strength and good durability. Purlins are widely used in buildings, bridges, docks and other construction projects.
The main function of purlins is to bear and disperse the gravity and load of buildings. In building construction, purlins are usually located at the cornice of the roof, which plays a role in supporting the roof structure and can disperse the weight of the roof and transfer it to the wall or supporting columns. In addition, purlins play a similar role in large-scale construction projects such as bridges and docks, which can enhance the stability and bearing capacity of the structure.
The selection of purlins should be determined according to the requirements of specific construction projects. Generally speaking, wooden purlins are suitable for light building structures, while metal purlins are suitable for projects that need to bear large loads and long spans. When selecting purlins, the corrosion resistance and durability of materials should also be considered to ensure that they maintain the integrity and stability of the structure for a long time.
In a word, purlin, as an important building material, plays an important role in structural support. Its material selection and use should be determined according to the specific engineering requirements to ensure the safety and stability of the building.
