Nov. 16, 1937. E. D. CODDINGTON STUD Fi1e d Sept. 3, 1935 I I I l 4 I 1 n n u a u r Patented Nov. 16, 1937 UNITED STATES PATENT OFFICE STUD Application September 3, 1935, Serial No. 39,023 Q 11 Claims.
This invention relates to compositestructural members designed to take the place of timber in building construction.
Structural members of the above character are commonly composed of a light sheet metal casing enclosing a nailable cementitious core and in building construction are superior to wood because of their greater strength and also because of their proof against fire and decay and the action of destructive insects. In addition such members possess advantages over metal structural I elements by virtue of their lighter weight and their capability of being sawed to length and nailed in position.
In the fabrications of such composite structural members simplicity of construction is a desideratum, admitting of rapid and economical manufacture. Such members heretofore have been commonly produced by rolling a strip of 2 sheet metal to desired shape, uniting the longitudinally-extending overlapped edges of the sheet so as to form a tubular casing and then filling the casing with a plastic medium which upon hardening forms a core. Another process for producing these members represents the subject of my copending application Serial No. 39,022 filed September 3, 1935, in which an intimate mixture of gypsum, Portland cement and sawdust is packed into the casing in a dry state, and moisture then introduced through perforations in the casing to supply the water of crystallization. But, however produced, an important objective is to 0btain a tight, rigid and permanent bond between the overlapped edges of the metal sheet composing the casing.
While it has heretofore been proposed to unite the edges of the casing by' an interlocked-seam, as disclosed by the patent of Bruner, No. 573,839, dated December 22, 1896, such a seam being disposed upon the exterior of the casing is disadvantageous because of the tendency for it to open during filling or in the course of the rough handling which such members ordinarily receive on the job, and also because such a seam forms a pertuberant ridge extending lengthwise of the member interfering with the attachment of floor and wall pieces thereto in flat face-to-face contact.
It-is an important object of my invention to provide a structural member in which the casing, composed of a sheet of relatively thin metal, is joined together at its overlapped edges by a lock seam disposed upon the interior of the easing and embedded within the core. The seam is thus concealed within the interior of the casing and protected against mutilation. To avoid lengthwise slipping of one of the overlapped edges of the casing relative to the other when the structural member is placed under stress, the seam is desirably formed with a series of inter- 5 locking depressions extending crosswise of the seam which depressions perform the additional service of stiffening the seam and keying the easing to the core.
The structural member is capable of employl0 ment as an upright or as a horizontal framing element so as to assume a load in compression or to withstand bending stresses. In order to effectively function as a horizontal element, such as a stringer, rafter or joist, (in which event the member is ordinarily supported upon one of its narrower faces), I prefer to locate the seam in a plane including its neutral axis so that any give" or flexing of the member within small limits does not impose any appreciable stress upon the seam.
It is also an object of my invention to provide a structural member in which the casing is formed with concave side walls so that a crushing force exerted between the opposite flat faces of the member, tending to cause inward yielding of the side walls, is resisted by the core material. In order to rigidify the casing one or more inwardly-directed, longitudinally-extending ribs may be advantageously formed upon its side walls.
The invention further contemplates the provision of caps for sealing the ends of the member, these caps preferably being held in association with the member by means of bendable ears carried by the caps and engaged within recesses in the sheet metal casingi However, these caps may v be held in place by other means, such as by nailing or soldering.
Other objects and advantages of the invention will become apparent from the following detailed description of certain preferred embodiments thereof, reference being had to the annexed drawing in which:
Figure 1 is a perspective view of one end of a stud having concave sides;
Figure 2 is a detail sectional view of a portion of the stud of Fig. l;
Figure 3 is a fragmentary detail view of the lock seam which unites the overlapped edges of the metalsheet forming the casing; 50
Figure 4 illustrates an end of the stud of Fig. 1 ptrogided with a cap for closing the,ends of the s u Figure 5 is a perspective view of a stud of generally rectangular section;
ing I enclosing a relatively hard cementitious core 2, the casing being formed of a single flat sheet of metal rolled into tubular shape. The longitudinally-extending edges of the sheet are folded together and united by a lock seam 3 forming a fluid-tight Joint coextensive with the length of the stud medially of its height. 'The metal sheet constituting the casing is of sufllciently thin gauge to permit nails to be readily driven through it into the core. dished so that the member is of least cross-sectional thickness midway of its height and is outwardly flared towards its top and bottom faces 2b.
The core 2 is composed of a mixture of ypsum, Portland cement and sawdust in approximately the proportions, by weight, 55:20:9, this i'lller being preferably packed within the casing in a dry state and afterwards wetted, as described in my copending application above referred to. Upon crystallization the confined material hardens into a solid core which completely fills the interior of the casing and serves as a nailing block which does not crack or crumble when nails are driven thereinto. In order to obtain complete and uniform curing of the filler, perforations l are formed in the casing (as shown in Fig. 2) through which the excess moisture contained in the filler may effect its escape. These perforations are located in the sides of the casing extending in pairs of parallel rows throughout the length of the stud adjacent its top and bottom. The perforations are punched inwardly so as to produce burrs is upon the inner surface of the casing which embed within the core and serve to anchor the casing thereto.
The lock seam 3 uniting the two overlapped edges of the metal sheet composing the casings is shown on an enlarged scale in Fig. 3. As illustrated in this figure, one edge of the sheet is bent into the form of an inwardly directed hook 30. while its other edge is offset inwardly at 3b so as to overlie the hook 3a. This oflset edge extends downwardly slightly below the end of hook 3a where it is rebent outwardly to form a second hook 30 which passes up into locking engagement with the hook 3a, leaving a small clearance space intermediate the end of hook 3a and the inception of hook 30. To compensate for elongation of the metal at the time the seam is formed, I provide upon the longitudinally-extending rib 3e thus raised upon the inside of the casing by the offset portion of hook 30 a series of transverse depressions 3), these depressions in the completed casing maintaining the hooks against longitudinal displacement and providing small recesses which are filled by the material composing the core and serving, like the burrs 4a. surrounding the perforations, to lock the casing to the core.
In order to rigidify the casing and to prevent its deformation while being packed with cementitious filling material in the course of manufacture of the stud, I provide an inwardly directed rib 5 arranged coextensive with the length of the stud upon the side wall 2a opposite to that which includes the lock seam 3. The rib is located medially of the height of the side wall corresponding to the location of the seam upon the opposite side wall so as to counterbalance the rigidifying effect of this seam. However, additional ribs may be provided if desired.
The sides 20 of the stud are In the preferred form of my invention clips are provided for closing the endsof the stud One such clip is shown in Fig. 4 in association with the end of the stud just described. This clip is fashioned from a flat, elongated strip of -nail-penetrable sheet metal bent into generally U-shape so as to define a cover portion to having a pair of parallel arms 6b extending at right angles thereto and overlying the flat top and bottom faces of the stud for a short distance inwardly from its end. The armsla at their ends are formed with laterally projecting ears to which are bent so as to curl around the corners 'of the beam and lock within slots 6d punched in the side walls of the stud. In order to prevent lateral play between the clip and the stud, the cover is stamped along two arcuate lines 6e to form ribs which contact the exposed faces of the dished side walls 2a adjacent the end of the stud (Fig. '1 By virtue of these clips the entire core I is enclosed in a protective and strengthening casing of sheet metal, through which nails may be driven.
The structural member just described is light and exceptionally sturdy, being ideally suited for use either as a horizontal or a vertical load sustaining member. As an upright member its strength in longitudinal compression is superior to that of a wood stud of equal cross-section. As a horizontal member it is adapted to withstand intense lateral'compression between its top and bottom faces by reason of the fact such compression tends to collapse the arcuate sides inwardly toward each other, which action is resisted by the intermediate body of filling material. Furthermore the casing of sheet metal protects the member by limiting the flexing thereof to a point beyond which injury to the core might result.
The stud, however, may assume other shapes than that of Fig. 1. For example, it may be of rectangular cross-section as illustrated in Fig.
. casing I is provided with perforations l3 extending in rows along its top and bottom to afford aeration of the filler. Rigidifying ribs I may also be provided upon opposite sides of the casing. The advantage presented by this form of stud is that all of its faces aflord flat nailing surfaces.
In Fig. 6 still another form of stud is shown.
This stud in all essential respects corresponds to the stud of Fig. 1 comprising a sheet metal casing l surrounding a cementitious core "5 and having the overlapped edges of the casing united by an internal lock seam .II. However in this structural member one of its sides I8 is approximately flat while its opposite side I! is concave. The casing is strengthened by a longitudinal rib 20 extending medially along one of its wider flat sides in a position corresponding to the seam l1 upon its concave side. This form of stud may be found desirable under certain conditions as an alternative for the studs of Figs. 1 and 5.
It is to be understood that the preferred embodiments of the invention described above are merely by way of example, and obviously the invention may be incorporated in other forms of structural members without departing from the spirit of my invention.
