Purlin roller frame play a vital role in steel structure engineering. It is the secondary load-bearing component in the steel structure roof system, usually made of C and Z type steel, used to support the main rafters and roof materials, to effectively transfer the roof load to the steel frame structure. The purlin roller holder not only carries the weight from the roof, but also ensures the stability and safety of the roof structure.
In practical application, the design and construction of purlin roll frame shall strictly follow the relevant specifications and requirements. The size, material and spacing parameters shall be accurately calculated according to the specific engineering conditions to ensure that they can withstand the expected load and meet the overall stability requirements of the structure. At the same time, in order to further improve the bearing capacity and stability of the purlin roller frame, a variety of supporting technologies and components will be used in the project to strengthen its stiffness, to prevent its deformation or damage when the external force.
In addition, the purlin roll rack also has a good economy. In the steel structure project with large span, the purlin roll frame can save the material, reduce the weight and increase the stiffness of the structure. This advantage makes the purlin roll frame in large public buildings, industrial plants and other fields have been widely used.
To sum up, purlin roll frame has an irreplaceable role in steel structure engineering. It is not only the key component to transfer the roof load, but also an important guarantee to ensure the stability and safety of the roof structure.
