Review article

The article considers large-span cross-core spatial designs (CCSD) made of polyvinylchloride pipes for coverings. Cross-core spatial designs (CCSD) of regular cellular structure are widely used in domestic and foreign construction for large-span coverings of buildings and structures for various purposes. A distinctive feature of the CPSS is the multiple repeatability of elementary cells having rectangular, triangular and other shapes formed by the same type of rods. Heat transfer in a spatial core plate for the boundary conditions of the upper and lower belts is considered. A calculation of the distribution of dimensionless temperatures with an illustration is submitted.
