Honeycomb recessed support beam - sawtooth-shaped recesses and beam halves welded at right angles

摘要

The building support beam is constructed from beams in which hexagonal recesses are cut in the webs. The beams are then longitudinal cut in halves, and these half sections welded together along an imaginary line to form ebam lengths at right angles, or in the case of three sections in a triangular pattern. The beam is constructed by welding sections e.g. (1.2) in such a fashion, that sawtooth tops are welded along imaginary line (10). Alternatively three half section may be welded together in a triangular cross sectional configuration.
