Application April 28, 1936, Serial No. 765848 Claims. (01. 189 36) This invention relates to improvements in in terlocking joints for metallic frames employed in building construction; more particularly, it relates to an interlocking joint for connecting col- 5 umn sections with each other and with the girders and floor beams at the different floors of the building. One of the objects of the invention is to provide an interlocking joint that will permit preforming of the structural'units so that they can be readily assembled and joined together without further shaping of the engaging parts, which are welded together to complete the joint.

Another object of the invention is to provide a structural column including a unitary section that extends through two floors of the building structure, with interlocking joints connecting the girders and beams of the respective floors to the unitary section.

The invention will be described in detail hereinafter, pointed out in the appended claims, and

illustrated in the accompanying drawings.

4 Referring to the drawings in detail, the column is formed of the main sections I and the auxiliary sections 2, assembled in vertical alinement with their ends abutting, and with the main sections alternating with the auxiliary sections.

The main and auxiliary sections are of H-shape in cross-area, each comprising a web member and opposite flange members secured together as disclosed in my previous patent, No. 1,911,413, dated May 30, 1933. Each main section I is'of such a .55 length as to extend through alower flooring and into an upper flooring. In the assembled relation of the column sections, the flange members at the lower end of each main section l are cut away to provide a tongue 3 at the lower end of the web member. At the upper end of the auxil- '5 iary section 2, immediately below, the web member is'cut away to provide a socket to register with the tongue 3. The tongue enters the opposite grooves 4 of the auxiliary section and is seated on the recessed end of the web of the latter. The 10 contacting. parts of the two sections are welded together.

a On the upper end of the main section l is seated the auxiliary section 2 immediately above, with the flange members of the two sections in 15 abutting relation. At this juncture of the two column sections an interlock is provided by the girders 5 to hold the column sections against relative lateral displacement. At this juncture of the two column sections the contiguous webs 20 are cut away at 6 to form a recess between the abutting end parts of the opposite flange members of theltwo sections. Extending through the abutting end parts of the flange members are the complementary slots 1 registering with the recess between the web edges 6. The slots 1 are in the same plane as the webs of the two sections; Secured to the outer face of each flange section I is the chair 8, slightly below the lower end of the slot 1.

The end parts of the flange members of each of the girders 5 is cut away to form the shoulders 9 at the end of each girder, and also to provide the tongue ID at the end of the web member. In the assembled arrangement of the girders and the column sections, as shown in Fig. 1, the shoulders 9 at the end of each girder respectively abut the outer faces of the flange members of thetwo column sections, above and below the complementary slots 7, with the lower shoulder 9 seated on i the adjacent chair 8. The tongue it of each girder projects through the complementary slots i into the recess 6. The extremities of the tongues l6 abut each other in a plane coinciding with the vertical axis of the column. Extending from opposite sides of the column and normal to the girders 5 are the supplementary beams II of I-shape in cross-section. Each one of these beams l l fits at its inner end between the flanges of the flange members of both the main section l and the auxiliary section 2 of the column. The inner end of each beam ll abuts the edge part B of the web of both the main and auxiliary sections of the column, and also abuts the meeting ends of both of the tongues lib All of column, the girders are positioned to seat the tongue II) in the slots 1 in the upper end of the main section, with the tongues abutting each other and the shoulder 9 of the girders abutting the flange members of the section, and with the girders resting on the chair 8. The auxiliary section 2 of the column is then seated at its lower end on the upper end of the main section, with the tongues iii engaging the slots I in the lower end of the auxiliary section. The beams I I are then positioned with their ends seated on the chairs I3 between the flanged sides of the main section. The ends of the'beams fit closely between the flanged sides and are prevented from upsetting thereby. The extremities of the beams abut the tongues I0, breaking joint with the same. The extremities of the beams also overlap the web sections at 6, 6 of the two sections. With the parts so arranged and welded together, a firm interlock is secured.

In the lower part of the main section I a mounting is provided for the girders and beams of a lower floor of the building structure. The web member of the main section is cut away to provide a. recess in the web between the edges I4, I4 of the web. The flange members of the main section are each slotted at I5 to coincide with the recess in the web member between the edges I4, I4 of the web. To the outer face of each flange member is secured a chair I6 immediately below the slot I5. The girders ll of the lower mounting, like the girders 5 of the upper mounting, have at the ends of their web members the tongues I8 and at the ends of their flange members are the shoulders, I9.

In assembling the parts of the lower mounting, the tongues I 3 are thrust through the slots I5 into the recess between the edges I4, I4 of the web member, with the tongues abutting each other and coinciding with the plane of the web member. With the tongues so positioned, the girders are seated on the chairs I6 and their shoulders I9 abut the flange members of the column section.

Associated with the girders H in the lower mounting are the I-shaped beams 20 extending from the column at right angles to the girders I I. The end of each beam is fitted between the flange members of the column section and is seated on the. chair 2! secured to the Web of the section below the lower edge I 4 of the web. The inner ends of the two beams 28 abut the meeting ends of the tongues I8 and also abut the Web of the column sectionadjacent to the edges I4 of the web. The several parts of this lower mounting are also welded together to form a unitary structure.

By providing at theupper end of the main section I amounting for the girders and beams of an upper floor, and by providing in an intermediate part of the section a mounting for the girders and beams of a lower floor, a column section can be employed that extends through two floors of the building under construction. In positioning such a column section, but little more effort is required than would be expended in the erection of a separate column section for each story. In the construction of a large building, not only'would there be an appreciable saving in labor, but there would also be a considerable the load of the building structure lessens toward the top and lighter column sections may be used to carry the girders and beams of the upper floors. As shown in Figs. 1, 2 and 6, each upper main section I is of less cross-area than V the auxiliary section 2 immediately below. To

accommodate the uniform shape of the girders and beams, the width of the web preferably remains the same throughout the several sections to maintain a uniform space between the flange sections. However, if lighter girders and beams are used in the upper floors, then the width of the web maybe reduced in the upper column sections to accommodate the narrower girders and beams.

In massive construction, the comparatively short auxiliary column section 2 facilitates the handling of the same and also in mounting thereon the next main section I above. In lighter construction, the auxiliary section 2 may be omitted and the higher main section mounted directly on the lower main section. When the auxiliary section is omitted, the length of the main section is increased to include an additional length equal to that of the auxiliary section. When column sections of the same length are employed, that is, each having a length to extend through two stories of the building, the mounting connecting the two sections is practically the same as the upper mounting shown in Figs. 1 and 2. Such a mounting is shown in Fig. 7. V

As illustrated in Fig. '7, the column sections are intended to be of equal'length, but the upper one having less cross-area. As indicated, the two

sections

25 and 26 are connected by an interlock provided by the girders 21 having tongues 28 projecting through slots in the contacting ends of the sections, and with the ends of the beams 29 (only one is shown) abutting and breaking joint with the abutting ends of the tongues. This structure is practically the same as the previously described interlock, shown in the upper mounting of Fig. 1; the only-difference is in the less cross-area of the upper section 25. To ac? commodate this difference in cross-area, the upper flange member of the two girders 21 and 2,8 is cut away less than the lower flange member to provide the further projecting shoulder 29 to abut the upper section 25.

The several girders illustrated have a strengthening rib SI! extending longitudinally of the Web member on both sides of the latter. The ribs 3|] are formed when .the web members are rolled. A rib 30 on a girder may also be utilized to support a minor floor beam 3|, as shown by Figs. 8 and 9. s V
