Abstract

Perfeccionamientos introducidos en la obtención de elementos prefabricados de hormigón precomprimido según las cuales el citado elemento consiste en una losa de reducido espesor con una armadura constituida por varillas de acero de alta elasticidad, que por relajación y adherencia ejercen una precomprensión centrada sobre la acción del hormigón, teniendo dicha losa sus bordes longitudinales perfilados a 45º de modo que constituyen dos chaflanes para su acoplamiento, así como su cara inferior fina y lisa, y la superior rugosa para facilitar el aferramiento del hormigón vertido sobre ella.
