E04B 1/20 - Structures comportant des éléments porteurs allongés, p. ex. colonnes, poutres, ossatures les pièces porteuses étant en béton, p. ex. en béton armé, ou en un autre matériau pierreux
This invention relates to a method of constructing a floor, comprising the steps of: (a) arranging a plurality of I- or H-shaped beams comprising at least one pre- formed beam with openings located in the web so as to form a support structure for floor units, wherein the or each pre-formed beam is or has been obtained by a process comprising the steps of: (b) taking a first I- or H-shaped beam, making a cut generally longitudinally along the web thereof, making a second cut generally longitudinally along the web thereof, the path differing from the first path of the first cut, the two paths being defined rectilinear sections lying on alternative sides of a longitudinal centre line of the web and at least partly curvilinear sections joining the closest ends of the adjacent rectilinear sections, separating the two parts of the beam; (c) taking a second I- or H-shaped beam, making a cut along the web thereof parallel to the longitudinal axis, separating the two parts of the beam; and (d) welding one part of the first beam to one part of the second beam; and (e) disposing floor units between the beams, the floor units being accommodated between the horizontal flanges of the beams.
