IMPROVEMENT OF REINFORCED CONCRETE ENVELOPES FOR LOW-RISE BUILDINGS

Abstract

Problem statement. A perspective direction to ensure modern requirements for thermal protection of buildings without a significant increase in material and labor resources and, most importantly, cost is the application of multilayer reinforced concrete panels, using efficient thermal insulation. In 2012−2013, some experience in the use of modern prefabricated three-layer reinforced concrete panels in cottage construction is obtained. This experience has revealed some shortcomings of such panels using on the building site and the need to modernize their production technology. In addition, improvements in joint construction and the use of aggregate concrete from recycled concrete scrap are relevant. The purpose of the article is to develop constructive solutions for low-rise buildings using multilayer reinforced concrete panels with effective insulation and to determine directions for further modernization of the developed structures. Conclusions. The developed constructive solutions for low-rise construction of houses using multilayer reinforced concrete panels with effective insulation are modern and exceed the standards for heat saving and are relevant today given the cost of energy. The developed constructive solutions of wall panels together with interpanel seams construction from the point of view of thermal homogeneity are the most homogeneous today in comparison with analogs. The panel joints construction is considered taking into account the conditions of durability and thermal conductivity. The directions of the developed constructions further modernization for wall panels and floor slabs are defined. The developed constructive solutions for panel house-building and factory production of wall panels and floor slabs reduce the time and cost of construction.
