REINFORCING CONCRETE.
- Specification of Letters Patent Patented Jamie, 1908.
Application filed November 15. 1906. Serial No. 343.645.
T 0 all whom it may concern:
Be it known that I, OTTO N. MUELLER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana,.have invented certain-new-and useful Improvements in Reinforcing Contion. 6
The object of my invention is to produce a I tion of a building, with my improved floor.
reinforcement arranged in connection with a metal skeletonready to receive the concrete. Fig. 2 a vertical sectionafter the concrete has been laid; Fig. 3 a horizontal section of a reinforced concrete structure with the floor reinforcement arranged to receive the concrete in accordance with my invention; Fig. 4 a vertical section through a column and adjacent floor -portions; Fig. 5 a detail of a slight modification.
In Figs. 1 and 2, 10 indicates vertical columns of any desired construction connected bylightbeams 11 referably of less depth than the thickness 0 the floors. Laid around each column and radiating therefrom across the space between that column and the adj acent columns are light reinforcing rods 12.
In erection, a. fiat centering is provided to support the concrete of the floor square, and the radiating ends of the reinforcing rods 12 are extended promiscuously across the "square, their ends being free and no particu- .lar attention being paid to the exact arrangement of the radiating rods, the only care necessary being to distribute the rods fairly evenly over the entire square. If desired, adjacent the outer walls, some of the rods 12, which are like rods 12, may be anchored to the light connecting beams 11 instead of beingidirectly wrapped around the columns. Also the radiating ends may be hooked over the tie beams, if so desired, to aid in erection.
The concrete 13 is then spread over the centering so as to embed the overlapping reinforcing rods 12. Portions of the lower course of rods 12 t. 6., those which lie immediately upon the centering, will be exposed upon the ceiling but these become lcovered "when the plastering 14 is applied. This may be overcome by hooking the radiating end over the tie beams so as to raise the rods sufficiently to place concrete under them.
In Figs. 3 and): the columns 100 are of the desired reinforced concrete construction and in connection with such a structure I prefer to use a reinforcing 'unit consisting of a bundle of rods 112- bound together for a very short distance at their middlesL To begin with, the rods ofeach bundle lie close together throughout their length and the bundle may be easily threaded through the rein-' forcement of the columns 100 before the concrete is applied and the ends then separatedand spread so as to be distributed over the square between adjacent columns. The concrete 113 is then applied in'the usual Well known manner, so t at the floors and col umnsbecome an integral structure. In this construction it is advisable to provide tension reinforcing members 115 extending di- I also rectly between adjacent columns.
deem it advisableto thread the rods 112 throughthe column reinforcement at a point slightly above the-upper face -of the finished floor squarefas shownin Fig. 4, sothat the radiating ends of the rods 112 will curve downward into thetfioor-square.
As previously, stated, by this construction I am able to produce a very strong floor without the use ofv beams between the columns of a depth greater'th'an the desired thickness of the floor.
I claim as my invention:
1. In a reinforced concrete structure, the combination, with a plurality of separated concrete columns, and the vertical reinforcement therein, of a set of reinforcing members embedded in a column and principally. supported thereby, the ends of said set of reinforcing membersbeing separated so as to radiate from the column support across the adjacent floor square to substantially all in, the said reinforcing members of each set being concentrated at one point in their length and principally supported at or near the point of concentration W ile the ends of said reinforcing members are separated so as to diverge from the point of concentration into variousportionsof the floor square. v
,3. In a reinforced concrete structure; a concrete floor square having a plurality of sets of reinforcing members embedded therein, the said reinforcing members of each set being concentrated at one point in their length and tprincipally supported at or near the point 0 concentration While the ends of I said reinforcing members are separated so as l. to diverge from the point of concentration into various portions of the floor square, the 15' said separated ends being unconnected.
In Witness whereof I have hereunto set my hand and seal at Indianapolis, Indiana, this 10th day of November A. 1)., one thousand nine hundred and six.
