Cold-formed thin-walled steel OSB light composite heat-insulation roof

Technical Field

The utility model relates to a composite heat-insulation roof, in particular to a cold-formed thin-wall steel OSB light composite heat-insulation roof.

Background

At present, with the aggravation of greenhouse effect, the global warming problem becomes more and more serious, and the concept of energy-saving buildings is more and more keen. Compared with the traditional building, the traditional light steel structure house has the advantages of low construction cost, wide application range and simple construction process; has strong environmental protection and is not easy to generate toxic substances. But as the building energy-saving standard is gradually improved on the thermal performance of the building enclosure, the steel component with lower thermal resistance has larger heat transfer capacity due to the existence of the steel structure, so that the average heat transfer resistance of the roof is reduced, and the thermal insulation performance of the structure is reduced. To make up for the lack of thermal insulation performance of traditional roofs, composite structures are often used to enhance their performance.
