Abstract
Precast blocks with a rectangular or quadrangular prism shape contain a normal weight hydraulic concrete casing, lightweight concrete or similar material, for building walls or slabs. The steel-reinforced blocks for walls, mezzanine or rooftop slabs have the length of the wall or slab to build. An acoustic, thermal-insulating lightweight material housed in the interior simultaneous provides for blocks sufficiently lightweight to transport and install manually on-site. For walls, the blocks are tongued and grooved on the top and bottom sides and placed horizontally one on top of the other using block or similar adhesive therebetween. In the corners or “T” intersections, blocks are alternatively placed and form armed headframes for stability and resistance. For blocks for slabs, the tongue and groove system is on the sides, installed one beside the other, using block or similar adhesive therebetween. Transversal rods to the slab are placed to avoid temperature retraction.
