' 3 Claims. (Cl. Ztl-92) ing from the oor above toprevent the transmission of sound and vibrations from room to room.
In the normal building construction of the multi-unit type wherein an occupied suite is superimposed on another suite, a problem arises in the transmission of noise from suite to suite when dry wall construction is used in the ordinary manner on the ceilinig. The usual manner of installing dry wall plasterboard is to nail it directly to the iloor joist when making a ceiling or to the studding for wall construction.
The-preferred embodiment of the invention disclosed herein is primarily adapted for use in the ceiling construction. When the dry wall panel is nailed directly to the lower side of the floor joist, the noise produced by walking on the oor above is transmitted directly through the the floor joist and the panel with the result that an undesirable disturbance in the room below occurs. In order to eliminate this disturbing sound transmission, a series of hangers areused which suspend the ceiling from the oor joist in such a manner that a barrier is produced which will not transmit the noise from the room above. Conventional furring strips are held in a stirrup-like hanger Vsupported across the width thereof, in such a manner that there is no tendency for thefurring strip to turn or twist. Also, the furring strip is against the joist during the nailing of the ceiling panel, which results in an unyielding structure in which to drive the nails. The separation of the furring strip and the joist is achieved automatically =by the deflection of spring-like portions of the hanger when the Weight of the ceiling is applied thereon. The springs further function to resist the transmission of vibration, and the transmission of sound from room to room, therefore, is substantially prevented.
Another object of this invention is to provide a hanger for suepending furring strips to which the dry wall paneling is nailed to form the ceiling.
A still further object of this invention is to provide a hanger which will hold the furring strips against the joist during the nailing operation when applying a dry wall plasterboard thereto and which will allow the furring strip to be suspended free of the joist when the weight of the plasterboard is carried thereby.
A still further object of this invention is to provide a ceiling hanger having spring sections included in the structure for resiliently carrying the ceiling structure, and preventing the transmission of sound through the hanger to the ceiling from the door above.
Another object of this invention is to provide a ceiling hanger having structure which permits the furring strip carried thereby to be held against the ceiling during the nailing operation and suspended freely of the joist to which the hanger is attached after the ceiling material has been nailed to the furring strip.
A still further important object of this invention is to provide a ceiling hanger which engages the bottom and sides of the furring strip which is suspended thereby and eliminates any tendency of the furring strip to turn or twist.
Other objects and advantages more or less ancillary to .the ceiling board installed;
3,046,620 Patented July 31, 1982 ICC the foregoing, `and the manner in which all the various objects are realized, will appear in the following description, which considered in connection with the accompanying drawings sets `forth the preferred embodiment of the invention. Y
In the drawings:
FIG. 1 is an elevational end view showing the hanger in place with the furring strip in position for nailing;
FIG. 2 is a side View of the hanger shown inV FIG. l;
FIG. 3 is an end view of the hanger of FIG.-1 with FIG. 4 is a modified view of the hangerof FIG. 1 wherein a slot for the nail is provided; and
FIG. 5 is the hanger of FIG. 4 in the position `assumed after installing the ceiling.
Referring iirst to FIG. l, a Hoor joist 10 is shown therein of the type usually found in buildings for ,supporting the flooring 12. The-floor 12 is in direct contact with the joist and aiXed thereto.
A hanger 14 of stir-tup configuration is aflixed to the joist 10 by nails 16 when the hanger is installed.` Afurring strip 18 lies in the rebent portion 20 of the hanger 14 and the hanger is so positioned when nails 16' are installed that the furring strip 18 is in contact with the lower face of the joist10. The hanger 14 includes springlike bends 22 which flex to allow vertical movement of the furring strip 18 when a load is applied thereto. This ilexing and the new position of the `furring strip 18 is better illustrated in FIG. 3 lwherein the ceiling panel 24 is fastened to the furring strip 18 by nails 26. Y
When the nailing has been completed, and the load of. y the ceiling panel 24 is allowed to be carried by the furring strip 18 by removing temporary support` required during nailing thus releasing the ceiling panel to apply the weight thereof to the furring strip 18, the hanger bends 22 are ilexed to a point that the furring strip V18 is separated from the joist 10. This -results in a gap between the furring strip 18 and the joist 10, incapable of installation, the hanger 14 and yfurring strip 18 are in the Y uppermost position and the nail 16 is installed at the lower end of the slot 28, in each leg of the hanger 14. When the ceiling panel 24 has been applied to the -furring strip 18, the hanger 14 moves downwardly until the upper end of the slot 28 engages with the nail 16. This feature provides for nailing the ceiling panel 24 to the l furring strip 18 while it is against the joist 10. and after Y the nailing operation is completed the hanger suspends the furring strip 18 in spaced relation to the joist 10. Bends 22 are provided for the spring action required to prevent the travel of sound and vibrations through the hanger 14 into the ceiling structure.
It is noted that in each instance the furring strip 18 is rmly and uniformly bearing against the joist 10 when n the ceiling. panel 24 is being installed, therefore, holding the furring strip `18 firmly in place during this operation. After the nailing has been completed, the weight of the ceiling construction accomplishes the separation of the furring strip 18 from the joist 10. Since the ceiling structure is in suspended relation to the iioor structure above and the suspension means includes a spring, there isY no path remaining for the sound vibrations from the iloor above to be transmitted to the room below.
A hanger construction has been described as primarily adapted for mounting a furring strip to a joist, from which a dry wall ceiling is to be suspended, however, the hanger would be equally as successful in insulating against the, travel of sound when other types of ceilings such as plaster, acoustic, wallboard, etc., are used. In other modications, the expanded metal lath or sheet rock lath would be nailed to the furring strip prior to the placing of the plaster thereon. The hanger disclosed herein therefore, is particularly adapted for suspending any sort of object below a horizontal building 'structure in such a way that transmission of sound and vibrations will be inhibited.
It is to be understood that the specific nature of the present disclosure is not intended to be restrictive or conning and that various rearrangements of parts and moditications of design may be resorted to without departing from the scope or spirit of the invention as herein claimed.
Having thus described our invention, what we claim and desire to be secured by Letters Patent is:
