This invention is an improvement on, and refinement of a previous invention registered in the US patent office by the same inventor in the same speciality field, that being reinforced concrete buildings of pre-cast elements that are assembled into a building on site. This invention consists of a pre-cast vertical wall (1) that bends 90 degrees and continues extending horizontally at the top and bottom ends for about one meter. About 20 cm before the end of these slabs, the thickness drops to half its previous dimension. At the end of the slabs there are steel reinforcing bars that protrude for about 30 bar diameters of the reinforcing steel. By placing a similar wall panel opposite to and facting the first panel with its protruding steel facing inward, and by fastening a steel form (3) to the bottom, on each side of the slabs both at the top and bottom of the wall, and then pouring concrete (8) a structurally continuous integrated square room is produced with a ceiling, a floor and a wall on each side. The central poured in place concrete portion can be replaced with a pre-cast slab to be secured at the ends by grouting, wleding or mechanical clamps. Similarly this same procedure can be applied to all four walls of a room instead of just two, in order to reduce even more the moments on the slabs in larger or heavier cases.
