Innovative Energy-Saving Sandwich-Panels for Industrial Construction

Abstract

Today, large-panel housing construction occupies a leading position, both in terms of construction speed and sales, which contributes to an increase in the volume of precast concrete housing construction. Outdated series of large-panel houses do not meet modern requirements. Old faceless panel houses are gradually replaced by beautiful housing complexes with different types of facades. At present, in the technology of construction of panel houses from sandwich-panels, the relevant trend is to reduce the standard thickness of the facade layer of a three-layer sandwich-panel (GOST 31310–2015 “ Three-Layer Reinforced Concrete Wall Panels with Effective Insulation. General Technical Conditions”) from 70 mm to 40 mm or less. Panel houses require a reduction in metal consumption, material consumption and improvement of thermal characteristics. This requires the development and implementation of new materials. The use of such construction products made of composite materials as diagonal flexible composite connections, flexible mounting loops and composite reinforcement mesh will make it possible to reduce the thickness of the protective layer of concrete without compromising the stability of the structure under the influence of the external environment due to the high corrosion resistance of the composite, reduce the weight of the panel, reduce the cost of manufacturing a unit of panel, increase the energy efficiency of the panel, ensure long-term strength of enclosing structures – create an innovative energy-efficient reinforced concrete sandwich panel of the XXI century.
