A building construction modular system utilizing interlocking building blocks made of aggregate material and having opposite side faces vertically and horizontally offset from the main body portion of the block. A structure, such as a wall, is erected by laying superimposed horizontal courses of vertically interlocked blocks, the blocks of a course being interlockingly supported by the blocks of the subjacent course. Each block element is provided with a vertically disposed passage or aperture and with a vertically directed recess at each lateral end of the block where it interlocks with an adjoining block element and the integrally formed transverse walls joining the side faces of each block are appropriately apertured such that, after the wall has been erected, cement is poured into the block structure from the tops of the blocks on the upper course, so as to flow vertically and horizontally through the passages and apertures within the blocks. Once set, the cement forms a lattice disposed inside the blocks, which strongly adheres to the interior surface of the blocks and rigidly holds the blocks in position. If so required, reinforcing metal rods or other elements are disposed horizontally and vertically through the passages prior to pouring the cement. The offset end faces of the blocks provide effective dams preventing the seepage of the liquid cement to the outside surface of the wall. The invention further contemplates appropriate corner blocks, wall end blocks, and interior wall connecting blocks, such that a complete system of modular element construction is provided by the invention.
A modular system of building construction comprising full blocks, half blocks, adaptor blocks, wall end blocks, corner blocks and wall junction blocks, each consisting of an interlocking block element comprising a main body portion vertically offset a predetermined substantially constant amount relative to a pair of opposed side slab portions integrally formed with said main body portion, said side slab portions being substantially mutually parallel and of equal dimensions, said main body portions being horizontally offset at least at one lateral end thereof relative to said side slab portions, whereby a plurality of said block elements are horizontally and vertically interlocked by overlapping stepped joints in surface to surface engagement when laid end to end in superimposed courses, each of said stepped joints being defined relative to a block element by at least a pair of edge surfaces disposed substantially one at right angle to the other, said main body portion of each block element being hollow and provided with at least one recess extending vertically from upper face to lower face of said main body portion and open to at least one lateral end of said body portion, said recess continuously extending horizontally and vertically behind said overlapping stepped joints and being adapted to receive mortar or cement poured within said wall structure for uniting each of said block elements with each other by allowing said concrete or cement to flow vertically and horizontally within said wall structure only and to set to a solid from whereby set mortar or cement is present within said wall structure behind each horizontal and vertical overlapping stepped joint forming an uninterrupted moisture, heat and wind barrier and said overlapping stepped joints forming a dam preventing seepage of mortar or cement through said joints to the exterior of said wall structure.
Interlocking block elements for erecting a wall structure having overlapping mortar-less joints, each of said interlocking block elements comprising a main body portion vertically offset of a predetermined substantially constant amount relative to a pair of opposed side slab portions integrally formed with said main body portion, said side slab portions being substantially mutually parallel and of equal dimensions, said main body portion being horizontally offset at least at one lateral end thereof relative to said side slab portions, whereby a plurality of said block elements are horizontally and vertically interlocked by overlapping stepped joints in surface to surface engagement when laid end to end in superimposed courses, each of said stepped joints being defined relative to a block element by at least a pair of edge surfaces disposed substantially one at right angle to the other, said main body portion of each block element being hollow and provided with at least one recess extending vertically from upper face to lower face of said main body portion and open to at least one lateral end of said body portion, said recess continuously extending horizontally and vertically behind said overlapping stepped joints and being adapted to receive mortar or cement poured within said wall structure for uniting each of said block elements with each other by allowing said concrete or cement to flow vertically and horizontally within said wall structure only and to set to a solid form whereby set mortar or cement is present within said wall structure behind each horizontal and vertical overlapping stepped joint forming an uninterrupted moisture, heat and wind barrier and said overlapping stepped joints forming a dam preventing seepage of mortar or cement through said joints to the exterior of said wall structure.
