Abstract
A formwork is structured of a lower substrate of beams that are supported on struts, and a substrate with identical beams supported on and perpendicular to the lower beams. Resting upon the upper beams, there are panels of wood that make up the surface of the formwork; the beams are formed from steel plate of great strength and small wall thickness. The beams (1) have a trapezoidal configuration with an upper projection forming a channel that holds wooden strips. The beams have lateral folds or lateral ridges for rigidity. The beams of the lower substrate rest upon bidirectional heads (4) having wings (16) and a lower cylindrical portion (14) that connects onto the upper end of a corresponding strut.
