My invention relates to ceiling structures and it has for its object to improve the construction and appearance of ceilings and also to provide an improved paneled ceiling of simple, inexpensive and durable construction which will possess certain desirable acoustical characteristics.

To these ends I have provided the improvements in ceiling constructions set forth in the following description, the several novel features of the invention being separately pointed out in the claims at the close thereof.

In the accompanying drawings:

Figure 1 is a perspective view of a portion of a hung ceiling constructed in accordance with this invention.

Figure 2 is a bottom plan view of a portion of the ceiling shown in Fig. 1.

Figure 3 is a section on line 3--3 of Fig. 2.

Figure 4 is a top plan view of one of the panelholding units forming part of the ceiling shown in Figs. 1 and 2.

Figure 5 is a side elevation of the unit shown in Fig. 4.

Figure 6 is a section on line 6-6 of Fig. 4.

Figure '7 illustrates an alternative form of hung ceiling structure employing the panel unit of Figs. 4, 5 and 6.

The embodiment of my invention illustrated in Figs. 1 to 6, inclusive, of the drawings comprises a sheet metal ceiling wall which is indicated generally at I0 in Figs. 1, 2 and 3, and this wall may be made up of a multiplicity of tile units like that illustrated in Figs. 4, 5 and 6. Each tile unit comprises a rectangular sheet metal member I I whose marginal portions are molded as heretofore with socket-bosses l2 and [3 to overlap and interlock as shown at I2 in Fig. 3 as has heretofore been common practice in all-metal ceilings, the circular bosses l2 being, as usual, apertured as at I4 to receive nails I5 by which the sheet metal member I I is fastened to the under side of a furring framework IB, Figs. 1, 2 and 3.

The furring framework It is fastened to angle iron purlins I! which, in turn, are fastened to i the lower ends of hangers I8 whose upper ends are embedded in a concrete floor or roof I9.

In accordance with my invention each sheet metal member II is formed at its middle and upon its bottom side with a shallow rectangular cavity 20 having rounded corners and of a size and shape to receive within it a panel 2| of acoustical board, millboard or other suitable material. The material of panel 2| is preferably a poor conductor of sound vibrations and of heat and in addition the panel imparts to the ceiling the ornamental eifect shown in Figs. 1 and 2.

The cavity 20 is preferably formed by molding the middle portion of the thin sheet metal member II with a. dome which is defined by four 5 inwardly sloping side walls 22 and a flat top wall 23 which, in some instances, may be made with a multiplicity of holes 24.

Each panel 2| is of a size and shape to fit snugly within its cavity 20 where it is securely held in position by means of tangs 25 projecting inwardly into the material of the panel from each side wall 22 as shown in Figs. 3, 5 and 6. Each tang 25 may be produced by means of a tool which is driven through the side Wall of the dome 16 of member I I after the panel has been placed in position within the same. Or, any other suitable means may be employed for fastening the panel within its cavity.

The furring grid framework I 6 is made up from wooden strips which may be one and one-half inches square in cross-section, or thereabouts, and covered with a sheathing 26 of sheet metal as shown in Fig. 3. Thus the above described ceiling structure is, in its entirety, fireproof while the panels 2| provide sound and heat insulation.

In the ceiling structure illustrated in Fig. 7 a wall 21 of Celotex, mill-board or the like, is nailed or otherwise fastened to the under sides of purlins 21 which are suspended from joists or 30 rafters 29 by means of hangers 30. To the under side of the wall 21 is nailed, or otherwise fastened,

a furring grid framework I6 to which the sheet metal members II of the tile units lI-2I are secured as described in connection with Figs. 1 to 6, inclusive. In this case the metal members I I of the tile units are preferably made with the holes or perforations 24 shown in Fig. 4.

The ceiling structure of Fig. 7 provides an efiicient barrier against the transmission of heat and sound.

In Figures 1 to 7 the top wall 23 of each sheet metal member I I serves as a seat for the panel 2| which is held in position against the same by means of the tangs 25 supplemented, if desired, by cement. Also, in all of the forms above described the bottom surfaces of the panels 2| are flush, or approximately flush, with the bottom surface of the wall.

What I claim is:

1. A ceiling structure comprising a horizontal wall of sheet metal molded to provide a multiplicity of panel-receiving cavities upon its bottom side which are arranged in rows, each cavity being formed interiorly with a seat for a panel; a

multiplicity of relatively thin panels of sound and heat insulating material each seated within one of said cavities; means fastening each panel within its cavity; a furring frame-Work to which said sheet metal wall is fastened; a second horizontal wall of sheet material disposed immediately above but out of contact with said sheet metal wall and to which said furring frame-work is fastened, and means above said second horizontal wall to which the latter is fastened and by which both of said horizontal walls and said furring frame-work are supported.

2. A ceiling structure comprising a horizontal wall of sheet metal molded to provide a multiplicity of panel-receiving cavities upon its bottom side which are arranged in rows, each cavity being formed interiorly with a seat for a panel; a multiplicity of relatively thin panels of sound and heat insulating material each seated horizontally within one of said cavities; means fastening each panel within its cavity; a furring grid frame-work comprising furring strips alternating with said cavities and to which said sheet metal wall is fastened, each strip of said furring frame-work being enclosed within a sheath of sheet metal; a second horizontal wall disposed above said first mentioned wall, and hangers through which said furring frame-work is connected with and supported by said second wall.

3. As a new article of manufacture, a tile unit for ceilings comprising a rectangular sheet metal member having its middle portion molded to provide a panel-receiving cavity upon the under side thereof surrounded by a flange whose marginal portion is molded with bosses to interlock with complemental bosses provided upon adjacent units, some of said bosses being apertured to receive fasteners by means of which the unit is secured to an overhead support; a panel of fibrous sheet material fitted within said cavity, and means fastening said panel in position therein.

4. A wall structure comprising a multiplicity of rectangular sheet metal panel-holding units having their marginal portions disposed in overlapping relationship and each molded to provide the same with a panel-receiving cavity upon its bottom side; a separate panel of sound and heat insulating material seated within each of said cavities; means fastening each panel within its cavity; a support for said units, and means fastening the overlapping marginal portions of said units together and to said support.

5. A wall structure constructed in accordance with claim 4 and wherein said means for fastening each panel within its cavity consists of tangs forced inwardly from the material of the side walls of said cavity into the material of the panel.

6. A Wall structure constructed inaccordance with claim 4 and wherein the overlapping marginalportions of the units are molded to interlock so as to mutually position each other laterally.
