Element based on modular wall structure of foam and concrete as well as method of and apparatus for making such element

An element based wall construction, process of modular construction and apparatus for constructing structures of spaced concrete cylinders (10) and beams (14, 100) and foam insulating blocks (50, 60). The wall construction includes spaced, vertical concrete cylinders (10) interconnected by horizontal concrete beams (14, 100), reinforced by centrally located reinforcing bars (42), with a pilaster (12) projecting inwardly beyond the cylinders (10) and beams (14, 100) to support roof and floor joists or trusses, and insulating foam blocks (50, 60) occupying the spaces between cylinders (10) and beams (14, 100). The process includes the construction of concrete column (10, 300) and beam (14, 100) forming assemblies interspersed with insulated blocks to form a complete wall structure for a building with exposed pilaster channels (200) at each floor and roof level connected to the beam (14, 100) and column (10) defining apertures, stabilizing the structure, and substantially continuously pouring concrete into the channels to create a unitary wall structure.
