PLATE WEB AND PROFILE ELEMENT

摘要

The invention relates to a web frame in the form of a plate having a flange welded along one side edge thereof. The flange is designed as a bulb body (2) projecting symmetrically or asymmetrically relative to the mid-plane of the plate (1) on both sides thereof. The bulb body (2) in cross section has inclined sides (5, 6) projecting from the plate (1) at an obtuse angle ( alpha ) of 100 DEG to 120 DEG which, via a respective edge side (9, 10) having rounded corners (7, 8) and formed parallel to the plate, passes into a common side (11) extending at right angles to the plate plane.
