<p>The present invention relates to a beam and a method of manufacturing the same. The beam is mainly intended for the laying up and anchoring of naked floors (9), e.g. naked floor elements, and/or columns, and includes a beam section (1, 2, 3, 4, 5, 8) filled with a suitable medium and having an open-mouthed, upwardly facing cross-section, possibly also reinforcement means (7). The beam is characterized by two parallel, substantially upwardly directed webs (1, 2, 3, 4) secured on a subflange (5), each web being provided with three longitudinally extending bends (2, 3, 4) in their upper edge portions. In these upper portions of the beam through-bores (16) are provided such that each bore (6) in a bent portion is corresponded by an oppositely located bore (6) in the not bent portion of the web.</p> |
