A New Level of Panel Housing Construction: Composite Diagonal Flexible Ties and Flexible Mounting Loops for Three-Layer Concrete Panels

Today large-panel housing construction is one of the most popular ways of construction of buildings for various purposes. Modern production technologies of these buildings make it possible to create comfortable, bright and high-quality housing complexes. However, the issues of thermal insulation remain relevant: requirements for energy efficiency of residential facilities are increasing, new materials and construction technologies are being introduced. The technology of construction of panel houses from concrete three-layer sandwich panels with insulation is widely used. Diagonal flexible ties are used for reliable connection of all sandwich panel layers. At the market of industrial construction the most common are diagonal bracings of stainless steel, which is the «cold bridge» because of which the energy efficiency of the house is reduced. Steel mounting loops designed for handling and installation operations form additional «cold bridges». These loops are not cut after installation of reinforced concrete sandwich panels, as a result of which they create temperature heterogeneity and cause freezing of condensate with the threat of slow destruction of the enclosing structure. The introduction of such construction products made of composite materials, as diagonal flexible composite ties and flexible mounting loops, will improve the thermal protection of buildings and provide long-term strength of the enclosing structures. High corrosion and chemical resistance of products, zero thermal conductivity and equalization of temperature non-homogeneity of the panel, the absence of «cold bridges», condensate and mold, while reducing costs and improving productivity-all this make it possible to build houses of improved quality. The calculation of heat losses of the building when using composite diagonal flexible ties and diagonal ties made of stainless steel is given.
