Abstract

Abstract A complete concrete structure, especially houses, having any desired architectural form and appearance is constructed in a series operations wherein the foundation, the interior and exterior walls, and the floor are constructed at the situs from a single basic, monolithic pre-cast modular concrete beam. Each beam is an elongated concrete member having a generally rectangular cross-section, and having a central aperture extending through the length of said beam. In addition, two opposite sides of the beam are provided with a plurality of lateral holes, and said sides are configured to have a longitudinally extending tongue and groove arrangement so that abutting modular concrete beams will interfit with one another. Either one or both of the other two opposite sides of the beams may be architecturally finished, depending on whether the beam is to be employed as forming a portion of the foundation, the upstanding walls, or the roof structure. The required electrical, plumbing and reinforcing elements, extend through the respective openings in the beams, and in addition to the tongue and groove interconnection between adjacent beams, a plurality of specially shaped connector members are provided for securing adjacent modular concrete beams together. In another embodiment of the modular concrete beam, the beam is formed of a composite structure comprising an internal hollow mold of frangible material such as polystyrene in intimate contact with an external concrete structure. The ends of the internal polystyrene mold as well as projections extending along the longitudinal sides thereof are exposed whereby the frangible ends or side projections may readily be cut out to enable the routing of service lines through the composite modular concrete beam.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 197 words
A composite modular concrete beam having a labyrinth of passageways therein comprising an elongated structure having a cross-section defining two opposed sides, a top surface, and a bottom surface, said composite structure being formed by: 1. an internal elongated hollow member made of insulation material and corresponding in length to the length of the modular concrete beam, said hollow member having a crosssection including a top surface, a bottom surface, and two opposed sides, with the cross-section of the hollow member being of smaller dimensions than the cross-section of said composite concrete beam, said hollow member being made of frangible material and including a plurality of unitary, spaced projections extending from the opposite sides thereof, with the opposite ends of said hollow member being closed, and; 2. a concrete structure extending about and in intimate contact with said hollow member along the top, bottom and opposite sides thereof, said concrete structure being of a thickness along the opposite sides of the hollow member such that the unitary projections of the internal hollow member are exposed, thereby enabling access through the unitary projections and the opposite ends of the frangible hollow member to the labyrinth of passageways therein.
Claim 2
Dependent Claim 197 words
A composite modular concrete beam having a labyrinth of passageways therein comprising an elongated structure having a cross-section defining two opposed sides, a top surface, and a bottom surface, said composite structure being formed by: 1. an internal elongated hollow member made of insulation material and corresponding in length to the length of the modular concrete beam, said hollow member having a crosssection including a top surface, a bottom surface, and two opposed sides, with the cross-section of the hollow member being of smaller dimensions than the cross-section of said composite concrete beam, said hollow member being made of frangible material and including a plurality of unitary, spaced projections extending from the opposite sides thereof, with the opposite ends of said hollow member being closed, and; 2. a concrete structure extending about and in intimate contact with said hollow member along the top, bottom and opposite sides thereof, said concrete structure being of a thickness along the opposite sides of the hollow member such that the unitary projections of the internal hollow member are exposed, thereby enabling access through the unitary projections and the opposite ends of the frangible hollow member to the labyrinth of passageways therein.
Claim 3
Dependent Claim 70 words
a concrete structure extending about and in intimate contact with said hollow member along the top, bottom and opposite sides thereof, said concrete structure being of a thickness along the opposite sides of the hollow member such that the unitary projections of the internal hollow member are exposed, thereby enabling access through the unitary projections and the opposite ends of the frangible hollow member to the labyrinth of passageways therein.
Claim 4
Dependent Claim 70 words
a concrete structure extending about and in intimate contact with said hollow member along the top, bottom and opposite sides thereof, said concrete structure being of a thickness along the opposite sides of the hollow member such that the unitary projections of the internal hollow member are exposed, thereby enabling access through the unitary projections and the opposite ends of the frangible hollow member to the labyrinth of passageways therein.
Claim 5
Dependent Claim 17 words
A composite modular concrete beam as in claim 1 wherein the hollow member is made of polystyrene.
Claim 6
Dependent Claim 19 words
A composite modular concrete beam as in claim 1 wherein the hollow member is made of two elongated sections.
Claim 7
Dependent Claim 26 words
A composite modular concrete beam as in claim 1 wherein the hollow member includes at least one intermediate baffle disposed between the ends of the member.
Claim 8
Dependent Claim 30 words
A composite modular concrete beam as in claim 1 wherein the hollow member further includes a series, of spaced, elongated, unitary projections extending from the top and bottom surfaces thereof.
