INTERLOCKING JOINT FOR IVIETALLIC FRAMES.

Application filed March 31, 1927.

This invention relates to improvements in interlocking joints for metallic frames where by the use of the rivets'or bolts is avoided, the structural units being shaped to uniform stock patterns.

In the formation of a joint of such material the units to be joined can. be readily positioned in engaged relation without previous tooling at the place of juncture, where room for tool manipulation may be circumscribed, and the work done by unskilled labor. More particularly, it relates to the formation of an interlocking joint between columns and girders whereby extensions of the metallic frame can be easily accomplished, as when a column is formed of sections and these successively added as the height of the frame progresses. The means whereby the joint is formed are described in detail hereinafter, pointed out in the appended claims, and illustrated by the accompanying drawings.

In the drawings, in which similar reference characters designate corresponding parts,

Figure l is a front elevation of a joint embodying the invention, in which abutting column and girder sections are joined together in interlocking relation.

Figs. 7, 8, 9 and 10 are detail perspective views, respectively showing lower and upper column sections and girder sections.

Fig. 11 is a detail perspective view of the saddle shown in Figs. 1 and 2.

Fig. 12 is a detail perspective view of the chair employed in the joint.

Referring to the drawings in detail, 10 and 11 respectively designate upper and lower sections of a column and 12 designates the gir ders. The column sections and girders are each formed with a web and flanged on both sides at each edge of the web. The web 13 of the lower column section 11 is cut away between the upper ends of the flanged sides 14, the end of the web forming atransverse abutment 15. The upper end of each flanged side is provided with a median longitudinal slot 16 in the same plane as the web 13, each slot- Serial No. 180,014.

ending a short distance above the transverse abutment 15. in the flanged sides at the inner ends of the slots 16 are the transverse abutments 1? alined in parallel relation to the transverse abutment 15 at the end of the web. Mounted on the transverse abutment 15 is the chair 18 (Fig. 12) fitting between the flanged sides 1%. On the under side of the chair is a vertical flange 19 extending across the abutment 15 and notched at 20 to engage the notch 21 in the web 13. The notch engagement be tween the flange 19 and the web 13 holds the chair against longitudinal movement on the transverse abutment 15. When the chair is in place its top is flush with the transverse abutments 17 in the flanged sides of the column section.

Mounted between the upper ends of the flanged sides 14 of the lower column section are the ends of the girders 12 with their extremities abutting. These ends rest on the chair 18 and their flanges are notched, as at 22, so that the webs 23 can slip into the slots 16 in the flanged sides of the lower column section with the lower edges of the webs seated on the abutment-s 1. In this way the load of the girders is distributed over the abutments 15 and 17 of the column section. As the webs of the assembled girders and column section are in the same plane, there might be a tendency of the opposing webs to effect a shearing action if they contacted edge to edge. This tendency is obviated by interposing the chair 18 between the edges. While two girders are shown with abutting ends, yet it is obvious a single girder, with a double set of notches, can be substituted for the two abutting girders.

To provide a mounting for the upper column section 10 on the lower section 11 at the interlocking joint the saddle 24 (Fig. 11) is employed. In its lower part this saddle has a T-shaped recess 25 to fit the upper flanged sides and upper part of the webs of the girders 12. The saddle its between the flanged sides at the upper end of the lower column sec tion 11. In the upper part of the saddle is the vertical recess 26. With the saddle, girders and lower column section in assembled relation, the web 13 of the lower column section and the vertical recess 26 of the saddle are in the same vertical plane. The upper column section 10 is positioned on the lower column section 11 with the lower ends of the flanged sides 27 of the upper section abutting the upper ends of the flanged sides Id of the lower section and with the lower end of the web 28 of the upper column section seated in the vertical recess 26 or the saddle. The lower edge of the web 28 of the upper column section is slightly cut away, as at 29, Fig. 8, between the flanged sides 27. The purpose of this is to provide space for the wall of the saddle between the top of the recess 25 and the bottom oi the recess 26. This space to accommodate the wall of the saddle must be provided as the top of the recess 25 is in the same horizontal plane as the abutting ends of the flanged sides of both column sections and as the bottom of the recess 26 .is somewhat above such plane.

In assembling the several parts to form the joint between the column sections and the girders, they lower column section 11 having been secured in an upright position, the chair 18 is first seated on the transverse seat 15 at the upper end of the web 13 of the lower column section. Then the girders 12 are positioned with their webs. 23 partly inserted in the slots 16 with the ends of the girders, abutting. With the girders partly seated, the saddle 24, previously mounted on one of the girders, is slid over the abutting ends of the girders to a position between the sides 1 of: the lower column section, Then the girders and saddle are completely seated in the upper end of the lowercolumn section with the ends of the girders resting on the chair 18 and the lower edgesof their webs resting on the transverse seats 17. at the lower endsof the slots 16 in the sides of the lower column section. The upper column section 10iis then placed end-toend on the lower column section with the lower end of its web 28 seated in the vertical recess. 26 of the saddle-24: and with the latter extending upwardly between the flanged sides 27 of the upper column section. lVith the parts so. assembled the parts are strongly interlocked to hold them against displacement particularly, thelower end of the upper column section is. firmly held to form a rigid continuation of the lower column section. Also, the saddle is firmly held in its vertical arrangement with respect to the column and the chair mounted in the upper end of the lower colzumn section. This is accomplished by the girders extendi ng' through the flanged sides of the lower column section and through the saddle positioned between the sides of said section, thereby providing an interlock between these parts that prevents lateral or transverse movementof the saddle relative to the column section. As the girders are maintained with their webs in the same plane as the web of the lower column section and as the chair is centrally seated on the weband be tween the flanged sidesv of the lower column. section; ..the chair is firmly held against lateral or transverse movement with. relation tothe lower colgun'm section. Consequently, the saddle and chair are maintained in perpendicular relation in the column so that the load imposed on the saddle is transmitted in partthrough the interposed girders to the chair and to the web oi the lower column section.

In Figs. at, 5 and 6 is shown a modified form oi? the saddle, which is adapted to the support oit minor girders on a major girder. In the modified form the saddle 28 has in its lower part a T-shaped recess 29 to lit the flanged upper side of a major girder 30. The upper part oi? the saddle has a flat face 31 from which project the four lugs 32 spaced apart, both longitudinally and transversely of the saddle. Mounted on the saddle are the abutting ends of the minor girders 33. The flanges of these ends are notched so that the girders can be seated on the face 31 of the saddle interlocking with the lugs 32. Thereby, a strong interlock is provided for the major and minor girders.
