Part as Senses forms another sheet metal plate that can also be used as a web. The recesses correspond approximately to those of the remaining portions are in their dimensions, so that in the preparation 2, virtually no waste results ^ "The attachment of these I webs to the lower flange is in these known embodiments |; however, it is relatively cumbersome and time consuming.

\ Srfindungsgemäß the fastening of the web Aiit the "imsbesondere from both sides arranged Stabeisen- or profile bars existing chord duroh in Stegdurchbreehungen attachable brackets or the like" Suitably, the lower flange is embedded prior to installation in concrete * so that an additional attachment of the erfindungsgei3iäßen bracket no longer necessary is·

The lower chord can consist of reinforced concrete, in which the lower part of the web waä , welded or arbitrarily inserted reinforcements are embedded.

(According to another embodiment of the invention, the web parts located between the recesses can alternately be bent out of the web, and provided with reinforcements and beaw *, or jointly with cemented concrete at the end,
