CONCRETE COLUMN.

Specification of Letters Patent.

Patented Dec. 1, 1914.

Application filed April 23, 1909. Serial No. 491,775.

To all whom it may concern Be it known that I, DANIEL B. DANIELSON, residing in Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Concrete Columns, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention has for its object to provide a concrete column construction with metallic reinforcements so constructed and arranged that vertical reinforcing rods of the column may connect with and constitute a suspension connection for radially extending supporting rods of the floor or other building structure supported by the column.

Another object of this invention is to provide novel means for connecting the supporting rods with the vertical column reinforcing rods.

With the above and other objects in view the invention consists in the concrete column herein claimed, its parts and combinations of parts and all equivalents.

Referring to the accompanying drawings in which like characters of reference indicate the same parts in the diflerent views, Figure 1 is an elevation of a column constructed in accordance with this invention with a portion of the reinforcement thereof exposed; Fig. 2 is a plan view thereof; Fig. 3 is a transverse sectional view through a column; Fig. 4 is a detail view showing a modified form of connection between the column reinforcing rod and the supporting rods; Fig. 5 is a plan view of a floor reinforcement wherein the form of connection shown in Fig. 4: is employed; Fig. 6 is a detail view of the tightening means for the supporting rods thereof; Fig. 7 is a detail view of another form of connection for the column reinforcing rod and the supporting rods.

In these drawings 15 indicates the vertical reinforcing fods upon which the concrete 16 forming the column is molded, said reinforcing rods being usually connected in any manner by tie wires 17 and having a wire 18 wrapped therearound before the cement or other concrete material 16 is poured into the mold which surrounds the reinforcement during the process of construction. At the upper ends of the reinforcing rods 15, just below the upper surface of the floor or other building structure supported by the column,

said reinforcing rods 15 are securedly con nected with radially extending supporting rods 19 which preferably pass diametrically across the column with a sutlicient bend between the two reinforcing rods with which they connect to cause them to avoid each other at the axis of the column, and then said supporting rods are preferably bent downwardly to form approximately an umbrella shape with the arched supporting rods corresponding to the arched umbrella ribs. In addition to the radially extending supporting rods 19 there are airs of parallel stringers 0r tie rods 20 crossing at the axis of the column at approximately the same elevation as the supporting rods and which serve to directly connect each column with the adjacent columns.

Besides the radially extending supporting rods 19 and the tie rods 20 each column is preferably provided with a series of ring shaped hoops 25 surrounding the upper ends of the column reinforcing rods 15, each hoop being of larger diameter that the one below, and secured to these hoops are inclined rods 26 to form therewith an inverted cone shaped basket-like reinforcement for the capital of the column. Also as shown in Figs. 1 and 5 there are rectangular frames 27 and crossed oblong frames 28 laid upon the umbrella shaped supporting reinforcements of the columns to form a net work of reinforcement centered upon the axis of each column to support the floor or other structure formed on the column and prevent its being punctured by the column.

With that form of the invention shown in Figs. 1 and 5 certain of the column reinforcing rods 15 have their ends bent to form hooks 29 engaging the supporting rods 19 and certain of the rods 15 project upwardly between the pairs of tie rods 20 and these are not bent but project above the surface of the floor supported by the column to serve as spotters to enable the columns of the different floors being positioned directly in alinement with each other.

In the form of the invention shown in Figs. 4 and 5, the supporting rods 19 instead of terminating a short distance from the column are bent toward the adjacent columns and are coupled with the ends of the corresponding supporting rods thereof, preferably by having loops 30 on the end of each surrounding the other with wedge blocks 31 therebetween for tightening the stretch from one column to the next. With this construction the hooked ends of the reinforcing rods 15 are merely engaged with eye 32 bent therein at an intermediate point to receive the supporting rods.

In the modification shown in Fig. 7 the end of the reinforcing rod 15 isbent to form an eye 33 to receive the supporting rods 19 in the same manner, this form of the invention closely resembling the form shown in Figs. 4 and 5.

With all of the forms of the invention the radially extending supporting rods for the floor or other structure supported by the col.- umn become rigidly connected with the vertically extending reinforcing rods 15 of the column when the cement or other concrete filling is molded thereon so that the supporting rods and the net Work of reinforcing rods Which is usually supported on them Will be suspended from the columns direct tosustain the Weight imposed upon them.

Copies of. this patent may be obtained for prisinga column having a plurality of verti-.

cally-extending reinforcing rods forming the frame WOI'k of said column, said rods being bent intermediate their ends to form "loops or eyes, and separate horizontally-extending rods passing through said loops for supporting the floors adjacent the column, theverticalrods in the column extending above and below the floors carried bysaid horizontally-extending supporting rods.

2. A reinforced concrete structure having vertical reinforcing rods forming the frame- Worlr of superimposed columns on different floors and bent at their intermediate portions to form loops or eyes, and separate radially extending supporting rodspassing through diametrically opposite eyes and extending beyond the column to form a suspension connection With the column reinforcelnent for the reinforcement of the structure supported by the column.
