[China Glass Network] Recently, several fires on curtain walls and metal roofs have been turned into fires from the fire of the stars and turned into fires. The fire hazards of these new materials being promoted and used must be paid attention to by all parties. Traditional insulation materials are non-combustible materials. It will not be lit, and will not become a fuse to expand the fire range. Nowadays, the extruded insulation board used everywhere has good insulation performance, small thickness and environmental protection, and it has many advantages. However, the danger of not being fireproof or even becoming a fuse has not yet attracted enough attention. Lighters are often not available at the site to prove their non-combustibility, but practice has shown that welding sparks or other flame temperatures are sufficient to ignite extruded boards. More dangerously, these materials can not only ignite, but also do not self-extinguish. What is even more terrifying is the rapid expansion of the combustion range like a fuse, which turns a small fire into a huge fire. These materials can continue to be burned even in confined spaces. The metal roofing insulation materials of the gymnasiums and cultural halls in Nanjing, Jinan, and Beijing are all closed and burned under the aluminum plates, making it difficult to save. The selection and promotion of new insulation materials must not only consider the insulation properties, but also pay attention to their safety and must have reliable fire performance. Aluminum has a melting point of only 700 degrees and melts quickly and loses its load carrying capacity. Steel profiles can support longer periods of time even without a fire barrier. The aluminum curtain wall and the stone curtain wall are opaque parts, and the skeleton is not exposed. Steel profiles can be used to improve the fireproof performance of the curtain wall. Glass curtain wall can also be used for cold-formed steel exposed beams and columns The cold-formed thin-walled steel has a beautiful appearance and a smooth surface, which is no less than an aluminum profile and has a fireproof performance far higher than that of an aluminum profile. Fully used for demanding glass curtain walls. Application of cold formed thin-walled steel Currently cold formed thin-walled steel has been used in curtain walls. The thin steel profiles meet the requirements of the industry standard "Cold-bent rectangular steel pipes for building structures" JG/T 178-2005. The design of cold-formed thin-walled steel members can be carried out in accordance with the Technical Specification for Cold-formed Thin-walled Steel GB50018. Smaller wall thickness: Beam: should not be less than 2. 0mm; Column: Not less than 2. 5mm; should not be less than 2.0mm.
