Certain industrial roof loads must be complied with to ensure the quality and safety of the factory. Workshops with corrugated iron roofs, whether large or small, have common standards. The factory roof load standard, including the load of the corrugated iron roof and purlins, will certainly be useful information for investors who have been and will be building industrial factories.
Through the process of designing and building a factory with many years of experience, after a preliminary survey of the work to capture the appropriate structures, the engineers design a drawing that accurately calculates the level of construction. bearing of the purlins to the foundation of the workshop. The purlins of the corrugated iron roof are separated and designed so that the standard load of the heavy-duty corrugated iron roof from the roof does not affect the nearby wall too much.
The corrugated iron roof of industrial buildings with corrugated iron roofs and purlins should have the following factors:
TCVN 2737:1995 Loads and impacts – design standards.
TCXD 229 -1999 Instructions for calculating the dynamic component of the load according to the standard TCVN 2737:1995.
TCXD 45:1978 Design standards for houses and buildings.
TCXDVN 293:2003 Heat protection for houses – Design guidelines.
TCXDVN 175:2005 Maximum permissible noise level in public works – Design standards.
TCVN 4059:1985 System of quality indicators of construction products – Steel structures – List of standards.
TCVN 4613:1988 Construction design documentation system – Steel structures – Conventional symbols and drawings.
TCVN 5889:1995 Drawings of metal structures.
TCXDVN 338:2005 Steel structures – Design standards.
TCVN 6170-4:1998 Fixed marine works – Part 4: Design of steel structures.
TCVN 6170-8:1999 Fixed marine structures – Structures – Part 8: Anti-corrosion systems.
TCXD 149:1986 Protects building structures from corrosion.
The common standard for the entire factory should force design engineers to ensure that the works are effectively placed and to avoid unnecessary errors that cause damage to buildings and properties, affecting the reputation. of construction contractors.
The construction of the factory corrugated iron roof combined with the roof frame and purlins may be the static load
+ 15kg/m2 - 20kg/m2 (corrugated iron + purlins), roof live load: 30kg/m2, if there is a suspended ceiling, plaster ceiling, it will be added to the dead load, TLBT purlin.
+ Roof sheet thickness (mm) 0.45 4,239 kg/m2, Hanging loads (ceilings, lights, ..) including: Collateral Load (Ceiling, Lights), Ceiling 9.58 (gypsum board thk 1.27cm), Insulation (cellular plastic) 20 (cellular plastic), Lighting 4.79, HVAC 4.79, Sprinkler (water spray) 7.19.
Standards also need to be strictly followed by workers to ensure during the installation and construction of heat-resistant corrugated iron roofs. With additional accessories, you can avoid unnecessary risks such as excess corrugated iron roof
The panels do not match together with the unreasonable slope of the corrugated iron roof along with further research on the proportions for the heatproof, heatproof and noiseproof part of the inner part of the corrugated iron roof without causing clumps or deflection of the nails. screw.
If these factors are ensured, it will not only help ensure the load of the corrugated iron roof, but also ensure the standard corrugated iron roof structure.
Non-technical standards
These are range standards for truss purlins to be used for a preliminary visual assessment without going through complicated and somewhat mechanical standards.
For technical standards, it is necessary to pay attention to the standards of corrugated iron material, purlin, corrugated iron roof truss, corrugated iron arm span. Those are the necessary criteria to ensure that steel-framed steel-roofed factory buildings are sustainable against environmental or climate impacts.
Standards for corrugated iron materials
The main factor that needs to be paid attention to when a quality product is expressed through the roof material. Depending on the purpose of use, you can choose 1-layer corrugated iron roof, 3-layer corrugated iron roof or quick-heat corrugated iron roof
After construction, it is necessary to check the quality of the roof, whether it is scratched or not, or if there is no rain or not
The factors worth noting because the goog beams help support the roof above the corrugated iron roof load, so for a product that wants to be tested and accepted well, it is necessary to ensure it is strong and safe with good support for the roof.
