(Summary description)News from this newspaper (trainee reporter Zhou Song) The 13th edition of this newspaper published on October 25, "Relevant departments: whether foam as a building material meets national standards for fire protection remains to be tested", reporting that the third phase of the university city Xi Street construction site uses foam as a building Building materials, citizens are suspicious. Recently, Chongqing Kaixilai Industrial Co., Ltd., the developer of the site, contacted this newspaper and provided it with the inspection report of the cast-in-place concrete hollow floor issued by the Municipal Fire Product Quality Supervision and Inspection Station. The report determined that the floor was in line with the state Fire resistance limit standard. The reporter saw in the inspection report that the samples submitted for inspection were sampled by the Shapingba District Fire Fighting Detachment on September 29 at the Xijie Street Phase III construction site in University Town and sealed up, and delivered to the Municipal Fire Product Quality Supervision and Inspection Station on October 22. The report inspection results show that the fire resistance limit of the sample reaches 90 minutes, and the fire resistance and heat insulation and fire integrity are in line with national standards. Chen Huaping, the engineering director of the project, told reporters that the current national technical standard for "Cemented Hollow Concrete Hollow Structure Forming Core Formwork" (JG/T352-2012) was formally implemented on May 1, 2012. In popular terms, the technology is to pre-embed a shaped polystyrene foam product with fireproof performance up to the design requirements in the cast-in-place concrete floor, and then pour the concrete to form the floor structure. Chen Huaping introduced that the use of this technology can reduce the weight of the building structure, increase the span of the building slab, and increase the net height of the room. Compared with ordinary cast-in-situ floor slabs, this technology also has better sound insulation and heat preservation effects.
