<p>Each of the building blocks (1) of this set has two channels extending parallel to its outer face (2) which forms a cornice. The channel (3) adjacent to this face is capable of constituting a gutter for receiving rainwater flowing off from the roof. As for the other channel (4), it is provided in order to serve as a leave-in- place form for the production of a reinforced-concrete horizontal anchorage (5) to the upper part of the corresponding wall. In addition to such building blocks of the standard type, blocks are provided of a similar form in which the channel intended to form a gutter comprises an orifice for the connection of a rainwater drain pipe. The present building blocks thus permit the simultaneous formation, at the upper part of a wall, of: a cornice, a gutter and a horizontal joining anchorage. <IMAGE></p> |
