| 摘要 |
The invention relates to a building element, which with two span openings is carried at three supporting points 2a, 2b, 2c, the element 1 having at least two spans functioning as load-bearing structure for the element between the supporting points. In the building element a reinforcement 6 has been arranged at the supporting point 2b between the two outer supporting points 2a, 2c, so that the reinforcement at least partially supports the loads engendered by the maximum bending moment M occurring at the supporting point 2b. <IMAGE>
