CONCRETE CONSTRUCTION.

Specification of Letters Patent.

'Application flled lil'ovember 16, 1909. Serial No. 528,274.

a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful improvements in Concrete Construction, (Case (i,) of which the following is a specification, reference being had thereinto the accompanying drawings.

This invention relates to concrete building structures and refers particularly to a construction in which superposed columns are joined to form a rigid and secure structare, and horizontal floor and ceiling mem-' bers are used and are supported at tion points of said columns.

,lt is the object of this invention to pro vide means for securing superposed columns rigidly together and, also, to unite the hori zontal floor or ceiling members together at the juncture of said columns to form a unitary structure...

in the drawings forming part of this the juncspecification, in which like numbers of referencodenote like parts wherever they occur, Figure 1 is a plan view; Fig. 2 is a sectional iiew on the line 2-2, Fig. 1; Fig. 3 is a perspective view of a casting for connecting columns together; Fig. 4 is a plan view; Fig. 5 is a sectional view onthe line 55, at; and Figs. 6 and 7 are perspective views of the means for binding columns together.

lln Figs. 1 and 2, the'casting shown in Fig. 3 is utilized, the same consisting of a base-plate 1, a top-plate 2, and a shank 3 firmly connected to both said plates. Long bolts 4: pass through perforations in baseplate 1, and are embedded deeplyin the concrete of cap 5 on column 6 thus binding said casting firmly to said column. Concrete beams 7 are formed between slabs 8 and over said base-plate 1, and additionally bind the same and shank 3. Bolts 9 pass through perforations in topplate 2 and through forations in the flange 10 of collar- 11,which not orlly encircles column 12, but binds the same. by reason of the same having been set within said collar. Reinforcing bars 13 extend underneath column 12 and through the space between plates 1 and 2, and underlap bars 14.,

In Figs. land 5, the alternate form of casting 15 shown'in Figfili and the casting 16 shown Fig, 7 are used. Each side of i said casting 15 is' 1 17. A bracket or projection 18 is formed on casting 15-and preferably extends entirely around said casting. Said casting 15 is secured to column 6 by bolts 4 which pass through perforations in the bottom of said casting. .The corners. of each slab 8 rest upon bracket 18 and said slabs are so arranged thata space 19 is left between each two adjoining slabs. A so-called form (not shown in the drawings) is placed underneath each two adjacent slabs, and grout orwetconcrete is poured upon said form and into said space19. The grout or wet-concrete in each space 19 is leveled off lush with the surface of slabs 8, and, when it sets, forms beam 7, the ends of which rest on bracket 18 .and unite said slabs integrally together. When the concrete is poured into each space 19 to form beam 7, it enters through each opening 17 and lills the interior space in said casting, thereby uniting all of said beams together over column 10. lteinforo ing bars 20 are embedded in the lower part of eachbeam 7, and, adjacent the end thereof turn upwardly and then extend through an openin or openings 17 and overlap rods 20 embed ed similarly in the beams 7 on the opposite side of said column. The casting 16, which is substituted for collar 11, is fastened to the casting 15 by the bolts 9. Each-side of said casting 16 is provided with a projection 21 or'a plurality of such projections. Column 12 is formed in cast in the space between projections-21 said column is firmly secured insaid casting.

I claim:

1. A. concrete structure comprising .a pair of superposed columns, a beam, and a casttween said columns adapted to bind said columnsto said beam, said casting comprising a base-plate, a top-plate, and sides uniting the same, each of said sides being provi ed with an opening through which the beam extends. I

2. A concrete structure comprising a pair of superposed columns, a beam, and a cast ing embedded in said beam interposed be! tween said columns adapted to bind said columns to said beam, said casting comprising a base-plate, a t0p-plate, and sides uniting the same, each of said sides being proprovided with an opening 0 )en'in 19 between the ad'oinim ed es of G C b mg 16 and by reason of the concrete enter-- -lfi'atennted Oct. 4, 1910.

ing embedded in said beam interposed bevided w' h an opening through which the castingand adapted to support said beam.

3. A concrete constructlon including a column, a base plate seating on the column,

bolts secured at one end to the base plate and projecting downwardly therefrom into the column, a top plate spaced from the base plate, a beam filling said space between the base and top plates, a collar bolted to the top plate, and a second column arranged in said collar.

4. concrete construction including a pair of superposed columns, a member seated on top of one column and formed with a surrounding bracket, a top plate on said member which supports the other column, sides formed with openings connecting the bracket and top plate, slabs seated on the bracket and arranged to have a space therebetween at points adjacent said memher, and a beam fillingthe space between the slabs and columns, and pro ecting through the openings of said sides to till the interior of said member.

5. In a concrete construction, in combination with a pair of spaced superposed co umns, a hollow member arranged in said space and formed with openings, slabs abutting said member and a beam arranged between the slabs, projecting through said openings of the member and filling the interior thereof.

6. In a concrete construction, in combination with a pair of spaced superposed columns, a hollow member arranged in said space and formed with openings, slabs abutting said member and a-beam arranged between the slabs, projecting through said openings of the member and filling the inemcee terior thereof, said member being formed with means on which the slabs and beam rest and receive support.

7. In a concrete construction, in combination with a pair of spaced superposed columns, a hollow member arranged in said space and formed with openings, slabs abutting said member, a beam arranged'between the slabs, projecting through said openings of the member and filling the interior thereor, said member being formed with means on which the slabs and beam rest and receive support, and a casting bolted on top or" said member and supporting the uppermost column.

o. In a concrete construction, in combination with a pair of spaced superposed columns, a hollow member arranged in said space and formed with openings, slabs abutting said member, a beam arranged between the slabs, projecting through said openings of the member and filling the interior thereof, and reinforcing bars passing through said openings in said member to strengthen the beam.

9. In a concrete construction, a beam, a series of slabs, a pair of spaced superposed columns, and an element mterposed in the space between said columns, said element being of box-like for; i having openings in its sides and also having means on its sides to support the slabs, said beam extendingv through said openings and filling the interior of said element.

In testimony whereof I have aflixed my signature in presence of two witnesses. I
