Steel structure purlin is a horizontal roof beam perpendicular to the roof truss or rafters, used to support rafters or roofing materials. The following is a detailed introduction to steel structure purlins.
Steel structure purlin is a horizontal roof beam perpendicular to the roof truss or rafters, used to support rafters or roofing materials. The following is a detailed introduction to the product:
Purlin, also known as purlin or truss, is a transverse bending (usually bidirectional bending) member. In steel structures, it is usually designed as a single-span simply supported purlin. Its main function is to support the roof of the building and ensure the stability and safety of the structure.
There are many types of steel structure purlins, including but not limited to:
1. Channel steel purlin: made of general channel steel or light channel steel, with good strength and stability.
2. H-shaped steel purlin: high-frequency welded H-shaped steel, good bending stiffness, easy to connect.
3. Curled channel steel (C-shaped steel) purlin: good interchangeability, less steel consumption, suitable for specific occasions.
4. Curled Z-shaped steel purlins: divided into straight curling and oblique curling, suitable for different needs.
5. Angle steel purlins: composed of single angle steel, simple structure, easy to process.
6. Combined purlins: such as combined Z-shaped steel purlins, combined tip steel purlins, etc., are connected by welding or bolts, with high strength and stability.
These different types of purlins have their own characteristics and are suitable for different building needs and scenes.
The installation and construction of steel structure purlins need to follow certain specifications and standards, including:
1. The installation of purlins should be carried out after the main body of the steel structure is adjusted to ensure the accuracy of the installation position.
2. The tie rods between purlins stabilize the purlins. During installation, the nuts on both sides of the purlins at each end of the tie rods must be tightened.
3. The purlin spacing is arranged according to the requirements of the construction drawings, and its error value should be controlled within the specified range.
4. After the purlin is installed, it should be inspected and accepted, and it can be transferred to the next process only after it is confirmed to be qualified.
Steel structure purlins play an important role in construction, including:
1. Providing support: supporting the roof and other structural parts of the building to ensure the stability and safety of the building.
2. Adjusting the height: In construction, the height of the building can be balanced and beautiful by adjusting the purlins.
3. Fixing components: As a fixing for connecting components, it is used to fix doors, windows, pipes and other components.
4. Protecting buildings: The surface of the purlin can be coated with waterproof coatings, anti-corrosion coatings, etc. to protect the building from rain, decay, insect pests, etc.
In summary, steel structure purlins are an indispensable and important component in construction. It provides the necessary support and stability to ensure the safety and durability of the building.
C-type purlins have various specifications. The C-type purlins produced by Liweiyuan Steel Structure include but are not limited to the following specifications: C160, C180, C220, C300, C350, etc. These specifications represent the different sizes and load-bearing capacities of purlins, which are suitable for different building structures and needs. The specific specification of C-type purlins to be selected needs to be determined according to the engineering design and actual use requirements.
