METAL BUILDING STRUCTURE.

Application filed August 29, 1922.

To all whom it may concern.

Be it known that I, HARRY KnAsNow, a citizen of Russia, and resident of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Metal Building Structures, of which the following is a specification.

This invention relates to metallic building structures, and particularly to columns or like elements, and the said invention relates particularly to novel means for providing columns of the character indicated with brackets or beam supports, although auxiliary thereto. Provision is made for supplying the column with a cap plate having novel means bv which it is anchored and associated with beam or girder engagement elements.

It is primarily a part of this invention to provide a column of the character indicated comprising a cylindrical metallic shell having a composition filling such as concrete or the like, brackets being also provided whereby beams or girders may have their ends supported in stepped relation to each other on the column; and the invention comprises other features which results in an advantage as to the stability of the structure and the facility with which the parts can be assembled, in addition to the latitude allowed in the manner of bearing or supporting surfaces, so that proportions may be changed to suit particular requirements without necessitating change in the fundamental structure of the device.

It is a further obiect of this invention to provide a bracket, the base of which is shaped to the curved contour of the outer wall of the said casing.

With the foregoing and other objects in View, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a view in elevation of the upper end of a column showing the same equipped with column supporting devices embodying the invention;

Serial No. 585,028.

Figure 2 illustrates a sectional View on the line 2-2 of Fig. 1;

Figure 3 illustrates a vertical sectional view thereof;

Figure 4: illustrates a perspective view of the cap plate inverted;

Figure 5 illustrates a perspective view of the column with the cap plate removed;

Figure 6 illustrates a view in elevation of the upper end of a column showing a girder in section;

Figure 7 illustrates a view in elevation showing fragments of two sections of a column with fastenings for anchoring one on the other; and

ld'igure 8 illustrates a view in elevation showing the application of the invention to a fragment of a building.

In these drawings 10 denotes the shell of the column, 11 the concrete composition filling for the same. In the present embodi' ment of the invention, the column supports comprise T-shaped brackets, the bases 12 of which are curved to the contour of the shell and are intended to fit closely thereagainst when they are secured in place by fastenings 13 such as rivets or the like. The inventor does not wish to belimited with respect to the fastenings, and under certain conditions, bolts could be employed and, of course, the shape of the head of the rivet is immaterial. The web 14 of each bracket may extend outwardly from the base to any appropriate degree, depending upon the area desired for the support of the beam. Preferably at the upper end of each web, angle plates 15 are secured to the sides of each web, and the flange of the angle plate which is not secured to the web has its outer face in alinement with the upper edge of the web, and by this construction, a relatively wide base or support for the I-beam or girder will be provided. Of course it will'be understood that the area or sizes of the supporting flanges of the angle plates may be increased or diminished to suit particular requirements. It will also be understood that the number of brackets may be increased or diminished, according to the number of beams to be supported, and their positions with relation to the periphery of the column may be made to accord with the direction Which the beam is to extend from the column.

In order to increase the sheer resisting effeet in the construction, a reinforcing plate 16 may be applied to the interior of the shell where each of the brackets is to be attached. When these plates are added, the lastenings or rivets will, of course, project through them and they will be secured in place simultaneously with the fastening of the flanges of the brackets.

The cap plate 17 may be secured in place in two ways, as illustrated. @ne of the means consists in providing the cap plate with apertures 18 to receive fastening-s 19 that extend therethrough and through the flanges of the angle irons; and the other method contemplates the use or flanged elements 20 that are secured to the under side of the cap plate, the said flanged elements having lips 21 that engage cleats applied to the interior of the shell, in the present embodiment of the invention, in contact with the reinforcing plates, and they may be secured by the same fastenings which are employed for ias'i'ei'iing the reinforcing plates. In some constructions, the reinforcing plates will be omitted perhaps, and in that event, cleats will be secured against the inner surface of the col um For most purposes, two cleats and two engaging elements carried by the cap plate will be employed, and when the cap plate is secured to the column, the cleat ei'igaging elements will be out of alinement with the cleats, and then by turning the cap plate, there will be an interlocking engagement between the cleats and the engaging elements, and when the shell is filled with concrete, parts will beheld in proper positions.

in some structures, the cap plate will be omitted, and in that event, the Fangcs of l-beams may be secured directly to the flanges of the angle irons by appropriate lastenings such as rivets, and inventor does not wish to be limite with respect to this application of the invention.

In Figure 8 a column shown, associated with and supporting a relatively heavy llbe'am 22 associated with a bracket 23 7 adapted to support a relatively lighter lbeam 2% wherein the supporting surfaces of the two beams are on the same plane. ln this construction, the bracket has a web and flange that is longer than the web of the bracket which supports the l-beam 22. The illustration just described is turnished for the purpose of illustrating the various ways by which the same invention may be used in practice, and, of course, other modilications as to proportions will present themselves to those skilled in the art. The bracket 23 may have a web longer or shorter in order that it will support beams of other dimensions in the same relation to the beam 22 as that shown, and the number of brackets en'iployed may also be varied to suit particular requirements.

ln Figure 7, a joint between two sections 2;? and 26 of column is illustrated, in which the brackets are oi the same construction as those heretofore described, but in this constri'iction, the flanges of the angle irons oil one bracket are secured to the flanges of the angle irons oi' the superimposed section, and by this means, continuous column is forn'ied. Furthermore, in this illustration, only two brackets of one section are shown as secured to two brackets of the other section, and an l-beam 2'i'isillustrated as being supported on the bracket of the lower section, and this illustration is provided convey the idea that the brac lets a means for coupling may be used either as as a support for a sections together, or beam.

It is also observed that the brackets on the lower section constitute what may be termed caps, and the brackets on the lower end of the upper section may be regarded as bases, so that when the caps and bases are secured together, the structure braced against lateral strain to a very marked degr e, the advantages of which will be apparent.

In the construction shown in Fig. 6, the brackets 28 constitute caps on which girder seats 29 may be secured in appropriate manner to retain girders 30 against displace- .ieut. The girder seats may be formed either of channel iron or angle irons, as those skilled in the art will understand.

The brackets are formed ol steelc and c bases thereoi are forged having a curve of the proper arc so that it will conform to tie outer suriace of the column to which the bases are to he applied.

1' claim:

1. In a metal structure, a cylindrical shell, brackets comprising steel bases shaped to the contour oi the outer surface or the shell and having webs projecting therefrom, angle irons secured to the webs their outer edges and constituting supports, reinforcing plates on the inside of the shell, and fastenings cal ending through the bases of the brackets, the shell and the said reinforcing plates.

In a metal structure, a cylindrical. shell, brackets comprising steel bases shaped to the contour of the outer surface of the shell and having webs projecting therefrom. angle irons secured to the webs at their outer edges and constituting supports, means for securingthe said bases to the shell, cap plates for the column, cleats on the inside or the column. meml'iers carried by the cap plate adapted to interlock with the cleats, and a composition within the shell for holding the cap late fasteniugs in place.
