At the 11th China (Beijing) International Building Energy Conservation and New Building Materials Expo held not long ago, a patented technology called the cast-in-place residential composite wall (non-combustible) structure energy-saving flame-retardant insulation integrated technology debuted and started the market. Promote the application.

The technology is to manufacture the structural grade of vitrified microbead flame retardant insulation board and steel mesh frame of class A flame retardant performance, and then cast it into the outer wall of residential building to realize the integration of building structure, flame retardant and heat insulation. We will guarantee the standardization of housing industrialization, component manufacturing, manufacturing and factoryization, and improve the construction technology level. According to Yu Ou, Assistant General Manager of Beijing Zhengyuan Tianrui Building Wall Insulation Technology Co., Ltd., the company can achieve 90% independent intellectual property rights from design, materials to construction technology. The technical classification is 100 meters high-rise residential version and 13 The new rural construction version of the layer, at present, the company plans to build a demonstration project in the Tongzhou Development Zone in Beijing. The construction with this technology completely replaces the traditional practice of pre-casting the main body and then the external wall insulation, so that the insulation and the structure have the same life, and the building energy saving is more than 75%, and the external wall insulation construction is repeated after more than ten years of new residential construction. The huge cost, a large reduction in construction waste, saving resources and costs. According to estimates, the construction of high-rise residential buildings with reinforced concrete shear wall structure system, the existing patented structure of cast-in-place residential composite wall (non-combustible) structure energy-saving insulation integrated technology can reduce the construction cost per square meter by about 80 yuan, which can reach green building. The three-star design review standard, the construction cycle can also be greatly shortened, and the economic benefits are very impressive.
