STRUCTURE OF CONCRETE AND IRON COLUMNS Filed Feb. 9, 1951 Bruno Bauer- INVENTOR= Patented June 13, 1933 UETE STATES BRUNO BAUER, OF VIENNA, AUSTRIA STRUCTURE OF CONCRETE AND IRON COLUMNS Application filed February 9, 1931, Serial No.

In the construction of multiple-floor'edifices, it is essential that the continuity of the longitudinal reenforced concrete columns be preserved and that there be no projections on the outside of such columns to interfere with their being smoothly wire encircled.

The object of my invention is to achieve these aims and I accomplish the result by 19 connecting together the abutting ends of the longitudinal reenforcing rods or bars by butt straps arranged on the inside of the column and bridging the joints.

Several forms of the invention are illustratively exemplified in the accompanying drawing in which all the views are in perspective.

The figures, l to 5, are perspective views of different forms of column reinforcements.

In Figure l longitudinal reinforcements are represented by angle irons a. Angle iron pieces 5 are used as angle butt straps for the angle irons a, and joined suitably by welding. In a similar way the angle irons b are connected with flat irons 0, the latter producing the efiect of distance pieces. This reinforcement is encircled by a wire hooping (Z.

In Fig. 2 the longitudinal reinforcements are likewise represented by angle irons a.

The corners of two U-irons e are applied as angle butt straps and Welded on the butts of the angle irons a. Both combinations are kept at a desired distance by the angle iron pieces 7", rigidly fixed on the same.

In Fig. 3 round irons g are shown as longitudinal reinforcements. Angle irons b are adapted to produce the butt joints, not directly in this case, butby interposition of bent sheets h, welded onthe lower butts. In this manner it is possible to transpose the upper butts somewhat towards the center line and to join them in this position by welding or fixing the angle irons b, which are connected together by distance pieces 6.

In this way it is made possible to fit the outlines of the total iron skeleton to the tapered shape of pillars or columns.

Fig. 4 shows also round irons g as longitudinal reinforcements. The angles of U- angle iron butt straps welded to the inner 514,339, and in Austria November 11, 1930.

irons e are adapted in the present form as total butt straps, while angle irons f are'used as distance pieces between the butt joints. The butts are transposed in the same way as In the preceding form, but by another arrangement. Lining plates h are inserted alternateiy at different sides between the lower and the upper butts, andthe U-ironangles.

Fig. 5 illustrates a joint part without the use of angle irons. The butts of the round irons g are joined by being welded on tube segments 2', the latter are connected in a desired distance, by the suitably adapted plates or flat irons 70. j

Changes may be made in size and relation and detail from that shown and described herein, without-departing from the spirit of my invention, but what I claim and desire to secure by Letters Patent is:

1. Reenforcing means for concrete columns for multiple-floor constructions, comprising a metal column consisting of longitudinal reenforcing members placed end to end, a hooping arrangement embracing said members, butt straps secured at the inside of said column over and bridging the adjacent ends of said longitudinal reenforcing members and spacers for said reenforcing members.

2. Reenforcing means for concrete columns for multiple-floor constructions, comprising a metal column consisting of longitudinal reenforcing members placed end to end, a hoop ing arrangement embracing said members,

faces of said reenforcing members over and bridging the adjacent ends thereof and spacers for said reenforcing members.

3. Reenforcing means for concrete columns for multiple-floor constructions, comprising a metal column consisting of longitudinal 96 angle iron reenforcing members placed end to end, a hooping arrangement embracing said members, angle iron butt straps secured to the inner faces of said reenforcing mem- N bers over and bridging the adjacent ends {)5 thereof and spacers for said reenforcing members.

4. Reenforcing means for concrete columns for multiple-floor constructions, comprising a metal column consisting of longitudinal re- 1'00 enforcing members placed end to end, a hooping arrangement embracing said members, U-shaped butt straps secured at the inside of said column to said longitudinal members Over and bridging the adjacent ends of said longitudinal members and spacers for said reenforcing members.

5. Reenforcing means for concrete columns extending continuously throughout the height of multiple story buildings, comprising a plurality of longitudinal superpositioned elements and a plurality of connecting means spacing said elements apart and joining the same rigidly together at the abutting ends to produce a continuous structure, saidconnecting means being Welded to the said elements-and arranged to leave the outer circumference thereof and the space enclosed bythe-elements unobstructed, and a spiral surrounding the said longitudinal elements, whereby the unobstructed outer circumfen enceofthe longitudinal elements and the unobstructed inside space a low easy adjustment of the spiral over the said elements, and a continuous concrete fill to be formed respectively.

6. Reenforcing means, as claimed in claim 5,,in Which the said longitudinal elements and the said connecting means consist of angle lrons.v

In testlmony whereof I aflix my signature.
