<p>At intermediate knots (4) of a pre-fabricated pillar (1) there are incorporated one or more bundles of metal pipes (6) which protrude from at least two opposite faces of said pillar and which are connected both mechanically and circuitally by an intermediate metallic box-type body (9), also incorporated in the pillar. Inserted through said pipes (6) are either the main or complementary reinforcement rods (10) of the flooring beams or panels abutting the pillar, so that said reinforcement rods (10) may have a structural continuity similarly to the reinforcement rods in said pillar at said knots. The reinforcement rods (10) are fixed and centered axially within said pipes (6) by means of conical and composite plugs (11) pressure-fitted in the ends of said pipes. The protruding portions of said pipes (6) are provided with vent holes (7) wherethrough expanding mortar may be injected into said pipes and, upon setting, it firmly secured the reinforcing rods (10) to the device of the invention.</p> |
