8 Claims.

This invention relates to columns useful in metallic building construction, and it has reference more particularly to built up hollow columns with laterally-projecting wings for cong nection of floor supporting beams and the like.

My invention has for its chief aim to make possible the rapid assembling of the wings with the columns, and at the same time'form a positive interlock between them for capacity of the wings to effectivelyresst downward displacement under the heavy loads carried by the beams connected to them, as well as to effectively resist sidewise displacement under lateral strains.

How the above and other objects and attendant advantages can be readily realized in practice will appear from the following description of the attached drawings,y wherein Fig. I is an axial sectional View of a building column conveniently embodying my invention.

Fig. II is a View of the column partly in plan and partly in horizontal section taken as indicated by the arrows II-II in Fig. I.

Fig. III is a fragmentary detail View of a portion of the hollow post component of the column.

Fig. IV is a perspective view of a block element forming a part of the column structure.

Fig. V is a view showing how the beam supporting wing components of the column are assembled with the post component.

Fig. VI is a perspective view showing the wings finally positioned and welded fast to the post component.

Fig. VII is a view corresponding to Fig. II showing how the wings are keyed in by concrete filling the post.

Fig. VIII is a view corresponding to Fig. I showing an alternative embodiment of my invention.

Fig. IX is a View partly in plan and partly in horizontal section taken as indicated by the ar- 40 rows IX-IX in Fig. VIII.

Fig. X is a fragmentary perspective View of a portion of the post component ofthe modified column.

Fig. XI is a perspective view of one of the wing components of the modified column.

Fig. XII is a View showing how the wing cornponents of the modified column are assembled with the post component; and

Fig. XIII is a horizontal sectional view taken as indicated by the arrows XIII-XIII in Fig. XII.

Fig. XIV is a perspective View like Fig. VI showing the final position of the wings and weldlng.

Referring first to Figs. I-VII inclusive,V my improved building column comprises a tubular post component I and wing components 2. As shown,the wing components 2 have web portions 3 extending outward through the narrow vertical portions 4 of invert T-slot's in the post I, and crosswise T-head flanges 5 within the post positioned with their inner faces spaced from the inner surface of said post. The T-head flanges 5 may be integrally formed with the wings or they may be separately formed and secured to the wings by welding or otherwise. Snugly fitting .I into the crosswise portions 6 of the invert T-slots in the post I Iand supporting the T-heads of the wings 2 are filler blocks I whereof one is shown in perspective in Fig. IV. The blocks 'I thus serve to prevent shearing of the post by the web portions 3 of the wings under loads carried by beams 9 which are rigidly secured at their ends to said wings by screw bolts I0. Prior to erection of the column, the wings `2 are permanently united with the postcomponent I by welding along the regions of mutual contact as indicated at I I and I'2 in Fig; V`I,andthe p'ost filled with concrete as vshown in Fig. VII to permanently key in the T-head flange ends of said wings. From Fig. V, it lwill be noted that the vertical dimension of the crosswise portions of the T- slots in the post I are such as to permit introduction of the T-head flange portions of the wings 2 at an upward angle. When the T-head flanges 5 are wholly within a post, the wing components are turned horizontally to the position shown in Fig. I, and the blocks 'I thereupon inserted beneath them in the crosswise portions of the slots. As a consequence of the described construction, it will be apparent that the wings 2 are rigidly interlocked with the post against the possibility of downward or outward displacement under load, and also against the possibility of lateral displacement under sidewise pressure or strain.

In the alternative embodiment of my invention shown in Figs. VIII-XIV, the inner ends of the wings 2a are stepped, the upper portions of the subdivisions so formed having transverse T-head fianges 5a and the lower over-reached portions having wider transverse T-head flanges la, which, as will be understood from further description, serve the same function as the blocks 'I of the first described embodiment. The flanges 'Ia may be integrally formed with the wings 2a or they may be produced by welding separately-formed strips to the opposite sides of the web 3a if desirecl or found convenient in practice. In the modified embodiment, the lower portion Ba of each invert T-slot in the post component Ia is of such depth and width as to permit insertion of one edge of the upper T-head iiange 5a of one of the wings 2a and thereafter allow the other edge of the ange to clear upon swinging the wing into radial alignment with the post, in the manner readily understood from Figs. XI and XIII. With the flange 5a now within the post la, the wing 2a is raised to engage its web 3a, in the narrow vertical portion 4a of the slot in the post la, and the wing thereupon moved somewhat further inward to seat its lower head flange 1a within the transverse lower portion 6a of the slot. After placement of the wings 2a as just explained, welding is resorted to as before, to Secure them permanently to the post along regions of mutual contact as at Ila, I2a, in Fig. XIV. Finally, the post I a is filled with concrete likewise as in the first described embodiment, with the result that the wings 2a are effectively keyed in against the possibility of either downward oi lateral displacement under load or sidewise pressure.

Having thus described my invention, I claim:

1. A building column comprising a tubular post; a beam-attaching wing with a transverse T-head flange within the post, and with a web extending outward through the vertical portion of an invert T-slot in the post; a block of a width corresponding to the T-head flange of the wing snugly fitting the crosswise bottom portion of the slot and supporting the T-head; and concrete within the post keying in the T-head of the wing.

2. A building column according to claim 1, in which the wing and the supporting block are welded fast to each other and the column along the regions of mutual contact.

3. A building column according to claim 1, in which the height of the crosswise portion of the T-slot in the post is such as to permit introduction of the T-head portion of the wing into the post from the exterior at an upward angle.

4. A building column comprising a tubular post; a beam-attaching wing with a vertical web extending outward through the vertical portion of an invert T-slot in the side of the post, said wing being stepped at its inner end with the upper part projecting inward beyond the lower part, and having a transverse T-head flange within the column, and the lower part having a transverse T-head flange, snugly lling the crosswise bottom portion of the T-slot; and concrete within the post keying in the upper T-head of the wing.

5. A building column according to claim 4, in which the wing is welded fast to the post along the regions of mutual contact.

6. A building column according to claim 4, in which the crosswise bottom portion of the slot in the column is of a size to permit introduction of upper T-head ange of the wing edgewise into the post and lateral swinging of the wing into radial position to bring said upper T-head ilange wholly within the post, so that said wing may be lifted bodily to engage its web in the narrow portion of the slot, and thereafter moved further inward radially to seat the lower T-head flange within the crosswise portion of the slot.

7. A building column comprising a hollow post; a beam attaching wing with a transverse T-head flange within the post, and with a web extending outward through the vertical portion of a T-slot in the post; a block of a width corresponding to the T-head iiange of the wing snugly fitting the cross-wise portion of the slot and with the web of said wing completely filling said slot; and concrete within the post keying in the T-head of the wing.

8. A building column according to claim '7, in which the wing and the block are welded fast to each other and to the column along the regions of mutual contact.
