ABSTRACT:
A building element of lightweight concrete is reinforced by at least one grid of heavy concrete arranged parallel to its lateral side faces, reinforcing rods connected to form a grid are disposed within said heavy concrete grid. Each of said heavy concrete grids, therefore, represents a covering of the reinforcing grid, thereby first obtaining rust protection for the reinforcing rods and, second, the bonding effect between the reinforcing rods and the lightweight concrete. A plastic and elastic expansion characteristic of lightweight concrete is thereby utilized to compensate the high amount of shrinkage of the lightweight concrete adhering to the heavy concrete grids so that the building elements remain free from fissures. The lightweight concrete is able to receive static stresses and is used for the reinforcement of the cells of the heavy concrete grid so that the cross-section of the rods of the heavy concrete grid may be reduced to a minimum. When two heavy concrete grids are provided, they are able to operate like girths for receiving tension and pressure, and the lightweight concrete corresponds to a web connecting the girths.
