This newspaper (trainee reporter Zhou Song) published in the 13th edition of the newspaper on October 25th, "Related departments: foam as a building material in line with national standards
This newspaper (trainee reporter Zhou Song) published in the 13th edition of the newspaper on October 25th, "Related departments: foam as a building material in line with national standards, whether fire protection is up to standard, pending inspection", reported the use of foam as a building in the third phase of the University Town Street Building materials, the public is suspicious. Recently, the developer of the site, Chongqing Kaixilai Industrial Co., Ltd., contacted this newspaper and provided the newspaper with the inspection report of the cast-in-place concrete hollow floor cover issued by the Municipal Fire Product Quality Supervision and Inspection Station. The report determined that the floor is in conformity with the country. Fire endurance standard.
 
The reporter saw in the inspection report that the sample for inspection was completed and sealed by the fire detachment of Shapingba District on September 29 at the third phase of the University Town Street. On October 22, the city was sent to the Municipal Fire Product Quality Supervision and Inspection Station. The test results show that the fire resistance of the sample reaches 90 minutes, and the fire resistance and fire resistance are in line with national standards.
 
Chen Huaping, the project's engineering director, told the reporter that the current national technical standard for "cast-out concrete hollow structure hole core mold" (JG/T352-2012) was officially implemented on May 1, 2012. The technique is generally preliminarily embedded in a cast-in-place concrete slab with a slab structure formed by pre-casting a shaped polystyrene foam product with a fire performance up to the design specification and then pouring the concrete. Chen Huaping said that using this technology can reduce the weight of the building structure, increase the span of the building board, and increase the indoor net height. Compared with ordinary cast-in-place floor slabs, this technology also has better sound insulation and heat preservation effects.
