Straight beam for use in curved suspended ceilings and method of making thereof |
摘要 |
A straight roll formed beam (20) for a curved suspended ceiling capable of being formed into a curve at the job site. The straight beam has cutouts (30) that leave a segment of the bulb (21) of the beam in place to give the straight beam rigidity after it is roll formed from metal strip (11). In the field, the bulb segment at a cutout is cut to permit the beam to be bent into a faceted curve. The bend at the cutout is fixed by a splice plate (40). <IMAGE> |
