Conformable wide wall angle
View Patent ↗A wide wall angle useful in locations of seismic activity to support ceiling tile and grid tees of a suspended ceiling comprising an assembly of an elongated base angle and an elongated extension strip, the base angle having generally perpendicular legs integral with one another and intersecting at a longitudinally extending corner, one leg being adapted to be fixed against a wall with the corner down, and the other adapted to project horizontally from the wall, the extension strip having a face with greater than the width of the horizontal leg, the extension strip having a multiple layer construction, two layers of the extension strip being held together in close parallel relation by an intermediate web integral with the layers, at least portions of the two layers being arranged to frictionally engage at least a part of the horizontal leg of the base angle spaced from the corner such that the strip can be assembled on and frictionally retained on the horizontal leg of the base angle, the horizontal leg of the base angle being disposed between the two layers of the extension strip.
1. A wide wall angle useful in locations of seismic activity to support ceiling tile and grid tees of a suspended ceiling comprising an assembly of an elongated base angle and an elongated extension strip, the base angle having generally perpendicular legs integral with one another and intersecting at a longitudinally extending corner, one leg being adapted to be fixed against a wall with the corner down, and the other adapted to project horizontally from the wall, the extension strip having a face width greater than the width of the horizontal leg, the extension strip having a multiple layer construction, two layers of the extension strip being held together in close parallel relation by an intermediate web integral with the layers and extending lengthwise parallel to the corner, at least portions of the two layers being arranged to frictionally engage at least a part of the horizontal leg of the base angle spaced from the corner such that the strip can be assembled on and frictionally retained on the horizontal leg of the base angle, the horizontal leg of the base angle being disposed between the two layers of the extension strip.
2. A wide wall angle as set forth in claim 1 , wherein said extension strip is formed of sheet metal folded on itself into three layers.
3. A wide wall angle as set forth in claim 2 , wherein a lower layer of said layers is wider than the remainder of said layers.
4. A wide wall angle as set forth in claim 2 , wherein two layers of said extension strip form a slot for receiving the horizontal leg of said base angle.
5. A wide wall angle as set forth in claim 4 , wherein the width of the slot is less than a face width of the extension strip.
6. A wide wall angle as set forth in claim 4 , wherein the width of the slot is at least as wide as the width of the horizontal leg of the base angle.
7. A wide wall angle as set forth in claim 1 , wherein two layers of said extension strip form a slot, an upper layer forming said slot includes a hem on a side adjacent a second intermediate layer, and a third layer forms a face of the extension strip.
8. A wide wall angle as set forth in claim 7 , wherein the width of said slot is less than the width of said face.
9. A wide wall angle as set forth in claim 8 , wherein the lower layer of said extension strip has a hem on a free edge, said free edge hem having a vertical dimension approximating the combined thickness of said three layers, including the slot formed by said intermediate and upper layers.
10. A wide wall angle as set forth in claim 1 , wherein said horizontal leg of said base angle has detent formations for engagement with a bulbous area of a layer of said extension strip.
