the case may be, of a building and are supported by columns 8. Said slabs are provided with downwardly extending flanges To all whom it may concern:

Be it known that I, JOHN E. CONZELMAN,

said slabs, by seating on the upper ends of said columns 8, and hate their opposing faces 3 inwardly inclined to form a wedgeshaped space 4. Said space is inclosed by suitable molding apparatus, and filled in with plastic concrete, which upon hardening, forms the beam 1. Said beam 1 extends continuously and centrally across the pillars 8 vented certain new and useful Improvements in Concrete Construction, of which the following is a specification, reference being had therein to the. accompanying drawmg. I

This invention relates to concrete building structures and has particular reference to a structure in which concrete slabs and l intermediate beams are used as ceiling and forming a line ot supports, and, as shown in Fig. 3, is wedge-shaped and is provided at its lower end with horizontally extended flanges 2 which underlie and support said flanges 5 of slabs 6. Reinforcing rods or bars 4 are embedded in the lower part of said beam, and, adjacent the ends thereof, turn upwardly and thence run longitudinally near the upper part of said beam.

This invention is not restricted to concrete'bcams continuous over supports, but. may be employed in the construction of any class of concrete beams having a cross section depicted as shown in Fig. 3.

Having thus described my invention, what. I claim and desire to secure by Letters latfloonmembers. and are supported at their corners or intermediate points and ends by i In the construction of concrete buildings members of-the structure.

It is the object therefore, of this invention to provide a structure of concrete building elements which coiiperate and are intercugaged to form a rigid, secure and lasting lt is also an object to provide a emu-rue building structure in \Vlll fll the general mmto present a neat appearam-c as well as to l.
