Components for constructing a ceiling grid across a span free of or with a limited number of suspension wires including main runners with a relatively high moment of inertia secured at their ends with brackets to wall moldings on opposing walls.

Free span ceiling grid system

A seismic bracket for supporting ends of suspended ceiling grid runners from a wall comprising a stamped sheet metal body, the body having a horizontally extending portion and a vertically extending portion, the vertically extending portion, in its installed position, rising above the top of a standard grid runner a distance at least 1&#xbd; times the height of such standard grid runner, the vertically extending portion having two sections generally coextensive in the vertical direction, a first section being integral with the horizontally extending portion and a second section arranged to be in a vertical plane that intersects a vertical plane occupied by the horizontally extending portion, the horizontally extending portion being arranged to support a grid runner to move longitudinally a limited distance, the second section of the vertically extending portion having an aperture for securing the bracket to the wall at a location substantially above the grid tee.

Seismic perimeter brace

A seismic clip for suspended ceiling grid tees that offers high strength, rigidity, versatility and ease of assembly while improving the ability of a clip to self-align with a grid tee. The clip includes a lanced tab that serves to establish and maintain alignment of the clip body and the tee to which it is assembled whereby a tendency of a clip to be tilted upwardly relative to the tee is eliminated or greatly reduced. The alignment tab serves to initially align the clip and tee either when it is assembled by snapping it over the tee or by sliding the tee endwise into the clip. The tab is configured so that it does not unduly add to the assembly force level when the clip is snapped over the tee or when the tee and clip are slipped endwise together.

Seismic clip

Clip for suspended ceilings

The invention provides a bracket and method of its use for adapting standard wall angle trim for use in sloped ceiling construction. The disclosed bracket arrangement can be used for the top edge or bottom edge of a sloped ceiling and be adjusted to match the angle of any practical ceiling slope. In disclosed embodiments, the bracket has the form of a rectangular flat steel sheet. The sheet has a hinge or bend line running lengthwise in its mid-area. The bend line is made by cutting the sheet intermittently along its length and thereby dividing the sheet into two sections. The cuts may be made, for example, by punching elongated slots along the bend line in a blank being formed into the bracket. Also punched into the bracket blank are a plurality of holes distributed lengthwise on marginal areas of the two sections of the blank.
