Optimized panel parameters for individual housing construction

Experience of low-rise residential houses design and construction built from factory-made reinforced concrete panel items is considered. It is noted that in this type of housing construction house-building plant and large-panel housing construction plants products is widely used. However, in most cases, products for multi-storey construction panel buildings are used directly for low-rise cottages. This approach is ineffective for many reasons, but mainly due to size and weight of the used products. The variant design made it possible to set optimized parameters for the length, height and weight of the exterior and interior walls load-bearing panels. Use of the double-layer exterior wall panels is the main technique that reduces buildings weight and allows variability of low-rise buildings facade finishes. The third layer exclusion makes it possible to reduce the exterior panels weight by 20–30%, increase the products length to 8.5 m, and reduce number of mounting elements in one- and two-story buildings by 25–50%, depending on the number of floors and buildings under construction spatial planning solutions. The above optimized product parameters for the low-rise panel buildings were tested during construction of 6 two-storey buildings with the area of 147 and 180 m2 in the Moscow region in 2022–2024. Based on these houses building experience effectiveness of their construction is shown. Usage of double–layer exterior wall panels with optimized parameters of other house kit products allows reducing the cost of one cottage house by 0.8–1 million rubles.
