The invention concerns a section system for the construction of beams of various lengths/heights on the basis of two simple components-asymmetrical I- sections (1) and interconnecting pieces (2). The vertical web part of the I-section (3) is provided with at least two pairs of projecting fastening grooves (6) positioned parallel to the longitudinal axis of the section and interconnecting with complementarily shaped protrusions (22) on the connection pieces (2). Fig. 3 illustrates a bearing beam for formwork. <IMAGE> |
