Abstract

An assembly of concrete structural elements includes a first and a second concrete lower column, and a first and a second column capitals are supported on respective upper ends of the respective first and second lower columns. At least one inverted beam is extended between the first and second column capitals. At least one lower flat surface of the inverted beam is positioned on respective edges of the first and second column capitals.

Claims

1. An assembly of concrete structural elements comprising:

a first and a second concrete lower column having a first and a second upper column end, respectively;

a first column capital supported on the first upper column end and a second column capital supported on the second upper column end, the first and the second column capital having a first and a second capital upper surface, respectively;

an inverted beam extending from a first beam end supported on the first capital upper surface to a second beam end supported on the second capital upper surface, the inverted beam including a flat upper beam surface, a first downward projecting leg extending between the first and second beam ends, and a first flat lower projecting leg surface extending outwardly from the first downward projecting leg below the flat upper beam surface between the first and second beam ends, the flat upper beam surface and lower projecting leg surface being separated vertically by a projecting leg height, the inverted beam being elongated in a first direction between the first and second beam ends; and

a plank having a first plank end supported on the first flat lower projecting leg surface, the plank having a plank height equal to the projecting leg height such that a flat upper plank surface is level with the flat upper beam surface, the first plank end extending vertically downward from the flat upper plank surface, the first plank being elongated away from the first plank end in a second direction perpendicular to the first direction;

wherein the first downward projecting leg angles away from the first flat lower leg projecting leg surface and the first plank end such that a horizontal gap exists between the flat upper beam surface and the flat upper plank surface at the first plank end; and

wherein a plurality of hook bars extending from the first downward projecting leg adjacent the flat upper beam surface rigidly tie the plank to the beam in an area below the horizontal gap and above the first flat lower projecting leg surface.

2. The assembly of claim 1, wherein the inverted beam further includes a second downward projecting leg extending between the first and second beam ends, and a second flat lower projecting leg surface extending outwardly from the second downward projecting leg below the flat upper beam surface between the first and second beam ends.

3. The assembly of claim 1, further comprising a rectangular block attached to the first downward projecting leg, and an upper surface of the rectangular block is level with the flat upper beam surface, and the first flat lower projecting leg surface extending outwardly from the rectangular block below the upper surface of the rectangular block between the first and second beam ends.

4. The assembly of claim 3, wherein the rectangular block includes a polystyrene foam interior portion and a concrete exterior portion.

5. The assembly of claim 1, wherein the inverted beam includes one or more pre-stressed cables embedded therein.

6. The assembly of claim 1, wherein the leveled upper beam surface and the upper plank surface are covered with a layer of concrete.
