Beam for a drywall ceiling soffit
A straight rollformed beam made for use in a suspended horizontal drywall ceiling is modified so that it can be used in a drywall ceiling underhang known as a drywall ceiling soffit. The beam is made with repetitive configurations along the length of the beam that are selectively cut, in the field, so that the beam can be bent to, and then fixed at, a desired angle. Drywall panels are secured to a plurality of such beams that form a framework for the soffit.
1. In a straight beam for a suspended ceiling, having an inverted T cross section, with a bulb at the top, a vertical web depending downward from the bulb, opposite extending flanges at the bottom of the web, a removable link in the bulb, and a hole in the web below the link; the improvement comprising a beam, with the link removed, formed into a fixed bend with
(1) bulb segments and web portions that overlap each other;
(2) means for avoiding interference between such segments and portions in making the bend, and
(3) screw means that extend through such segments and portions to fix the bend.
2. The beam of claim 1 , in combination with beams having identical fixed bends, that form a grid for a ceiling soffit having drywall secured to the grid.
3. The beam of claim 1 , wherein a bending score is formed in each flange to retain the bend at the score.
4. The beam of claim 1 wherein the overlapped web portions and bulb segments on one side of the bend are forced off center in the bend, so there is no interference with the overlapped web portions and bulb segments on the other side of the bend, which remain centered.
5. The beam of claim 4 , wherein bulb segments on both sides of the bend are flattened.
6. The beam of claim 5 , wherein a stiffener is formed in one of the bulb segments.
