Precast reinforced concrete column and beam members with preformed structural continuity in the interconnection zones, characterized in that the columns (1) are positioned in pairs side by side with a spacing between them which is less than the length of the interconnecting beams, and windows (2) aligned with each other and of a size suitably greater than the cross-sections of the interconnecting beams (7) are provided in the connection zones to the said beams, these beams being provided in their intermediate part with means (8) for connection to a sling (9) of the site crane, by means of which each beam is first offered up to the side of one column (1) and one end is inserted into the connecting window (2) of the other column (1) until the other end of the beam reaches the space between the two columns, after which this end is aligned with the corresponding window in the second column and the crane reverses the lateral movement to insert this end of the beam into the window in the second column also until the beam is supported on the two columns in the predetermined way, means being provided for subsequently securing the beams to the columns. <IMAGE>
