Abstract

A short span flat drywall ceiling construction comprising a pair of spaced parallel wall angles facing one another, the wall angles each having a vertical leg secured to vertical support surfaces and a horizontal leg cantilevered from its respective vertical leg towards the other wall angle, a plurality of substantially identical roll-formed sheet metal tees extending between the wall angles and vertically supported thereby, each tee having a main body formed of a single strip of sheet steel, the tee having a horizontal single layer lower flange, a vertical double layer central web disposed above the flange, and a bulb at the top of the web centered on a plane of symmetry, a sheet metal U-shaped reinforcement channel fitted on a central part of the length of the tee such that it is in contact with at least the sidewalls of the bulb.

Description

BACKGROUND OF THE INVENTION

[0001] The invention relates to building construction and, in particular, to short span flat drywall ceiling construction.PRIOR ART

[0002] A type of ceiling construction found in commercial buildings involves the use of horizontally spaced inverted metal tees suspended by wires from overlying structure. Sheets of drywall are fastened by screws to these metal tees and then are taped and otherwise finished. Building areas such as corridors, stairwells, landings, and small rooms found in apartments, condominiums, hotels, motels, dormitories, and the like are commonly finished with flat drywall ceilings. These building areas are typically relatively narrow and, therefore, involve a relatively short span from wall-to-wall. In many instances, the space or plenum above the ceiling, especially in corridors and hallways, is occupied by duct work, conduit, and mechanical equipment. The presence of this and like equipment frequently interferes with the installation of s...
