2023-09-21
Purlin machines are mechanical equipment used to produce purlins, which are horizontal components distributed along the length of the roof, located on the main rafters and supporting the components of the secondary rafters. Purlin machines have the characteristics of high work efficiency, simple operation, convenient maintenance, and can be supplied in various models and sizes. Classified by production materials: cement purlin machine, channel steel purlin machine. Purlin machine products are mainly used in industrial and agricultural buildings, vegetable greenhouse columns, grape frame columns, orchard columns, livestock farms, flower planting shed columns, farms, large-span factories, etc.
The formwork can be designed as single span simply supported components and continuous components.
When the span is greater than 9 meters, lattice members should be used, and the stability of the compression flange should be verified.
Lattice type purlins can be planar, spatial, or bottom supported purlins.
Solid web purlins should use rolled edge groove shaped, inclined rolled edge cold formed thin-walled steel, and Z-shaped cold formed thin-walled steel with straight rolled edges.
