<p>The bearing elements of completely reinforced lightweight concrete structures consist of slabs (1), linear beams (2-7), columns (8-11) and wall (12, 13) which are either monolithic, precast or combine; they are components used for building various structures such as slab structures or structures with bearing walls, frame structures, arch structures, grill structures or shells. These elements are competitive for building all kinds of structures due to their low weight, which is 4 times lower than in conventional reinforced concrete, good insulation properties and low cost of construction. They are a combination of reinforcement steel and lightweight concrete body. Their bearing capacity, in slabs (1) and walls (12, 13), and especially in beams (2-7) and columns (8-11), is ensured by their reinforcement framework which is always designed as a structure within a structure. The method of placement and continuation of the reinforcement ensures local stability or the reinforcement bars in the compressive and shear regions. The regular form of the elements makes possible the application of different construction methods for building structures of various forms which enables architects and engineers to have greater creative freedom.</p> |
