A lattice-type beam for reinforcing cast walls or floors consists of two longitudinal booms (1, 2) and diagonal rods (3) running between them, in which the diagonal rods (3) take the form of a sheet-steel strip bent zigzag fashion and running in the lattice-type beam which is secured at its bends to the booms (1, 2) which also consist of sheet-steel strips. The ensure simple production and great rigidity, the width of the trough-shaped sheet-steel strips of the diagonal rods (3) and the width of the booms (1, 2) extend transversaly to the central longitudinal plane of the beam and the sheet-steel strip of the diagonal rods (3) have a portion running parallel to the booms in the region of the connecting points (4).
Une poutre d'armature en treillis pour parois ou plafonds en matériau coulé se compose de deux membrures longitudinales (1, 2) et de barres diagonales (3) intermédiaires constituées d'un ruban d'acier plié en zigzag traversant la poutre en treillis et relié par ses points de pliage aux membrures longitudinales profilées (1, 2) également en ruban d'acier. Pour simplifier la fabrication et assurer une rigidité plus grande, la largeur du ruban d'acier en forme de gouttière utilisé pour les barres diagonales (3) et la largeur des membrures longitudinales (1, 2) s'étendent transversalement par rapport au plan médian longitudinal de la poutre en treillis. Dans la zone des points de raccordement (4), le ruban d'acier constituant les barres diagonales (3) présente une partie parallèle aux membrures longitudinales.
