This invention relates to improvements in concrete building structures and particularly to a novel form of concrete column for buildings of diiferent types.

5 One object of the invention is to provide a column construction which will facilitate the placement of floor or partition members.

Another object is to provide a column construction wherein the floor, girder or cross-beam supporting portions of the column can be incorporated in the building either at the time the building is erected or subsequently.

Expressed in detail, the present column might be said to be of a composite nature in that there is a main column and a supplemental column each composed of vertically disposed reinforced concrete units with the units of each column spaced one from the other. The units of each column are secured together by bolts or other 2 fastening members which project through the spaces thus provided without interfering with the metal reinforce bars, such fastening elements protruding into recesses at opposite sides of the columns to permit the attachment of nuts or the like. Some of the bolts project through both the main and supplemental columns and thus secure the two columns together into the so-called composite structure. The main columns extend the entire height of the building but the units of the supplemental columns terminate at the proper elevations to support the girders or joists for the floors. By reason of the supplemental columns being secured in place by bolts extending through spaces in the main columns, such spaces being formed at the time the main column is erected, the supplemental columns can be installed at any time subsequent to the erection of the main column.

Another object is toprovide novel means for tying the cross-beams or other horizontal structural elements of the building into the columns.

A still further object is to erect a building of multiple stories or floors in which the transverse members or beams are offset laterally with respect to one another toward the outer walls of the structure with the beams of the upper floors or stories located nearest said outer walls.

Another object is the provision of a novel con struction of interlocking means for superposed sections of vertical sectional columns which will permit transverse members such as girders to be formed with a portion of said interlocking means embedded therein.

With these and other objects in view, the invention consists in certain details of construction and combinations and arrangements of parts, all as will hereinafter be more fully described and the novel features thereof particularly pointed out in the appended claims.

Fig. 12' is a detail, longitudinal section of an end portion of one of the column units.

The present column is of a composite nature in that it is composed of one or more, so-called, main columns and one or more supplemental columns. Both the main columns and the supplemental columns are formed of reinforced concrete units, usually pre-cast, and secured together during the erection of the building by suitable ties or fastening members. For instance, as shown in Fig. 2, a corner column comprises main column units A, A, B, B, and the supplemental columns S, S, this being the preferred arrangement for buildings only a few stories high. Fig. 5 illustrates the construction of exterior columns intermediate the corner of the building and interior columns used in partitions. The exterior intermediate column, as shown, comprises main column units A, A, B, B, and supplemental units S, S, at three sides thereof. Similarly, the interior column may consist of main column units A, A, B, B, and supplemental units S, S, at opposite sides thereof for the purpose of supporting cross-beams.

Each column unit is cut away at certain of its corners, forming recesses 20 when the several units are assembled in the column, and the several units of the column are spaced apart transversely to accommodate tie rods of fastening members which pass through metal plates 2| in said recess and securely hold the units together in the column. Certain tie rods 22 (Fig. 3) extend through only the main column composed of units A, A, B and B, while other rods 23 are longer and extend between the supplemental units S, S. Plates 2! extend the full height of the column, and, if desired, individual plates 2| may also be provided at opposite ends of each rod. By taking up on the nuts 24 on the various tie rods, the various units of each column can be securely fastened together. Preferably, tie rods 22 are also placed in the spaces between the supplemental units and those of the main column. With this arrangement, it is a very easy matter to install additional supplemental column units after the erection of the building. The spaces between the main column units are, of course, permanent, so that any time it is desired to install additional units, either for new partitions or otherwise, additional tie rods can be inserted through the already erected columns to embrace such new units.

In order to securely interlock cross-beams such as illustrated at 25, in Figs. 1 and 5, with the units of the main columns, and at the same time provide reinforcing means for said cross-beams, elongated tie rods or reinforce bars 26 are embedded in the cross-beam, but with their ends exposed for anchoring attachment to said columns. Referring particularly to Figs. 2 to 5, this attachment consists of plates 21 threaded on the ends of bar 26 against a nut 28 and said plates are provided with apertures for reception of the protruding ends of rods 22. If desired, washers 29 may be provided on each of the rods between plates 2i and 2| and plates 27 are secured on rods 22 by nuts 24. In erecting the building, the nuts 28 are first threaded on rod 26, followed by placement of plates 21 and washers 29 thereon. The ends of rod 26 are then placed in openings in plate 2! with rods 22 inserted in openings in plate 2?, after which nuts 24 are threaded on the rods 22. Rod 26 can then, if necessary, be properly tensioned by means of the turnbuckle 25 (Fig. 1). With the rod 26 thus securely held in position, the cross-beam is poured in a suitable form so arranged that the beam will be supported on the upper surfaces of the supplemental column units S, S.

A modified cross-section for the column units is illustrated in Fig. 6. In this instance, the units are formed with longitudinally extending ribs 3| having undercut side faces. The units are assembled in the usual spaced relation with ribs 3! opposed and V-shaped plates 32 placed to engage the undercut side faces of the opposed ribs. Tie bolts 22 are then inserted through openings in the plates and nuts applied to both ends of said bolts at opposite sides of the opposed ribs. If desired, additional plates 33 can be provided between plates 32 and the undercut surfaces of the ribs.

For the purpose of securing superimposed units in a column, said units may each be provided with a socket 34 at one end and with an embedded, longitudinally extending bar 35 of suflicient length to project beyond the opposite end of the unit. When one unit is placed endwise upon another, the lower unit has the projecting rod 35 at its upper extremity and said rod is positioned in the socket of the other or upper unit. Thus, transverse displacement of the superimposed units is prevented. Preferably, the sockets 34 are lined with a short length of pipe.

It will be understood that the so-called main columns composed of superimposed units A, A, B, B extend the full height of the building, but the supplemental column units S, S terminate at each floor level or any other point at which some horizontal structural element of the building is .to be supported. It will also be appreciated that any number of reinforce elements or rods may be incorporated in the individual units and their presence will not interfere with the tie bolts 22, 23, because of the transverse spacing of the units in the column.

In erecting a multi-storied structure of any appreciable height, the arrangement of corner columns and cross-beams shown more or less diagrammatically in Figs. 7 to 11, may be used. This arrangement consists in assembling a plurality of the multi-unit columns at each corner of the building and at suitable points intermediate the corners, the several units of each column being tied together as previously described. A corner column is shown in Fig. 8 and an intermediate column in Fig. 11. The pre-cast beams 25 are secured in place as described, but at each of two opposite sides of each floor, two beams are used as shown, one beam being located flush with the outer faces of the columns and the other s'paced "inwardly therefrom. However, as the height of the building increases, the inner beams are located comparatively close to the outer beams. For instance, Fig. 8 represents the location of the beams at one side of the building at the fifth flooor of the structure illustrated in Fig. '7, and Fig. 9 illustrates the beams at the sixth floor of the building. Fig. indicates the beams as placed in the walls for the seventh floor, that is, the double beam arrangement is used at two opposite sides on one fioor and at the other two opposite sides on the next succeeding floor. It is, of course, not necessary that the inner beams of each two alternate floors be offset with respect to each other. For instance, as indicated by the thickness of the corner column in Fig, 7, the inner beams of the third and fifth floors may be in the same vertical plane, as would also be those of the second and fourth, the initial offsetting taking place at the sixth floor.
