The beam body for a wall comprises a lower rail (10) and an upper rail (20), which define a wall plane (P) and have a U-shaped cross section with several beams extending between them. The beam end parts are connected with the rails. The beams are arranged in a number of units (30), each of which comprises a number of beams (31,32) positioned widthways to each other in a direction across (N) the wall plane. In each beam unit, the beam end parts are arranged between the U-flanges (10b,c, 20b,c) of the rails. |
