INVENTOR BEL/NO E BBL l DUF' We 2 I ATTORNEY Patented Dec. 8, 1936 UNITED STATES PATENT OFFICE FIREPROOF BUILDING CONSTRUCTION Bruno E. Balduf, Chicago, 111., assignor to United 'States Gypsum Company, Chicago, 111., a corporation of Illinois This invention relates to -buflding constructions, and has reference more particularly to building constructions in which metal studs and framework are used to support composition boards.

In the construction of dry wall partitions, floors and ceilings, it is desirable to attach composition boards, such as gypsum or fiber boards, directly to steel studs and framework of a building. Methods and means for accomplishing this end previously proposed, have been found to be laborious in field erection and the units have been expensive to construct in the factory. It is also desirable to provide a. frame construction suitable for use in the outside walls of buildings.

An object of this invention therefore, is to provide a building construction utilizing composition boards directly attached to metal studs and framework of a, building.

Another object of the invention is to provide a construction of the class described which may be easily and cheaply constructed in the factory and erected in the field with a low labor cost.

A further object of the invention is to provide a steel frame construction suitable for forming the outside walls of buildings; also to improve building constructions in other respects hereinafter specified and claimed.

Reference is to be had to the accompanying drawings forming a part of this specification, in which Fig. 1 is a perspective elevation of my improved partition structure, I

Fig. 2 is a sectional plan view through the partition taken on line 2- -2 of Fig. 1,

Fig. 3 is a sectional plan view at the junction of a partition and intersecting wall,

Fig. 4 is a sectional planview of two intersecting partitions at the corner of a building,

Fig. 5 is a perspective view of a partition stud combined with an expansion member,

Fig. 6 is a sectional plan view through the stud taken on line 6-6 of Fig. 5,

Fig. 7 is a sectional plan view taken on line of Fig, 1 showing the manner of attaching the studs to supporting runners,

Fig. 8'is a sectional perspective View showing joists in a building construction, and

Fig. 9 is a sectional plan view through a modisecured in pairs to opposite sides of the channels inserted in the hole and tightened to draw the board tightly against the plate l3. If abutting edges of the board lie opposite the stud channels I0, they are attached in the manner above described, the joint is filled with a cementitious joint filler, and the exposed surfaces of the boards are decorated with plastic paint, Wall paper or the like. It will be seen that boards 38 do not touch the stud flanges l2 between the plates l3 and are free to vibrate under sound waves impinging against the wall face. The partition thus acts as a membrane and has a high acoustical or sound absorbing value, especially for sound. waves of low frequency. The partition also exhibits marked-sound insulating value.

Thetops of channels III are seated between flanges iii of channel runners l9, said flanges being connected by webs 20 which are provided with spaced perforations 2| for nailing attachment to the ceiling of a room, or other building framework. A similar bottom runner 22 with Web 23 and flanges 24 receives the bottom ends of channels In. In order to lock the stud channels H1 in place, runner flanges l8 and 24 are bent inwardly at the time of erection between said channels In to form locking detents 25 (Fig. 7) Runner flanges l8 and 24 are provided at intervals with a plurality of spaced perforations 26 to receive the board attaching screws I5.

In some cases, itis desirable to provide an extension member 28 at the top ofthe stud in order to accommodate varying ceiling heights. This extension member is preferably U-shaped and includes channel legs 29 having flanges 30, said flanges being cut out for clearance to permit bending so as to form the connecting channel member 3|. Perforated plates 32 are secured between the inside of flanges 30 by spot welding or riveting, so as to give clearance past the perforated plates [3. The board attaching screws l5 engage in the perforations in plates 32 and theboards then hold the extensions 28 in, the desired adjusted position. The channel legs23 fit before the assembly of boards It so that said extension members may be readily moved to give the desired length to the stud. Connector strips 32a are secured to the bottoms of flanges 30 to make sliding connection with the stud flanges |2. The detents 25 are pressed about the tops of extension members 28 as above described in order to hold the tops of said extension members inposition.

In assembling intersecting partitions as illustrated inv Fig. 3, and informing corners of rooms as illustrated in Fig. 4, runners identical with runners I9 and 22 and having channel webs 34, are attached to perforated plates |3 by screws 35 which pass through boards I6 and engage in the perforations in the plates l3. Outstanding flanges 38 formed on the channel web 34 extend at right angles to the boards l6 and are perforated to receive screws 31 for attaching boards 38 to said flanges 36. In order to provide framing for doors 40 and windows, (Fig. 4) wooden strips 4| are secured between channel flanges ,|2 by screws 42 engaging in drilled holes in the web Suitable door jambs 43 and trim 44 may then be attached to the strip 4| by nailing. Channel studs I may be made of heavier construction (Fig. 8) and placed in a horizontal position to form girders and joists, ceiling boards 46 and floor boards 41 being then attached to the perforated plates |3 by screws in the manner previously described.

In the modified form of construction shown in Fig. 9, stud channels 50 have outstanding flanges which are secured together by perforated plates 52. These plates 52 have center sections 53 which are bowed inwardly between the stud channels 50 and each plate is provided with one or more pressed integral stiffening ribs 54 to hold said plates in shape against the pressure of board attaching screws 55 which engage in the perforations in said plates. Boards 56 made 'of fiber. and being of semi-flexible nature, are secured to the plates 53 by screws 55, and are arranged in edge abutting relation adjacent the plates 53. The pressure of the screws bends the edges of boards 56 slightly inwardly to form a face cavity 51 so that the joint may be leveled off with cementitious material 58 and plastic paint to form a strong, reinforced joint due to the excess cementitious-material at the joint.

I would state in conclusion that while the illustrated examples constitute practical embodiments of my invention, I do not wish to limit myself precisely to these details, since manifestly the same may be considerably varied without departing from the spirit of the invention as defined in the appended claims.
