Abstract
An interlocking block for constructing walls without mortar at bed joints includes an inner wall, an outer wall, and a web arrangement connecting the walls, wherein upper and lower surfaces of the block when in use are formed in contact with walls of a mold, and the block is slipped from the mold in a direction parallel to the mold walls. Interlocking recesses and ridges are formed in one piece with the walls of the block. The web is minimal in cross-sectional area and is positioned at one end of the block and between the top and bottom to create large empty volumes defining vertical and horizontal passages. The block can include one or more intermediate walls parallel to the inner and outer walls and additional webs to connect the intermediate walls to the inner and outer walls.
Claims21
A construction unit comprising:
- an inner wall;
- an outer wall substantially parallel to said inner wall;
- and
- a web arrangement connecting said outer wall to said inner wall,
- wherein said inner wall and said outer wall together define an upper surface and a lower surface, both said surfaces are for engagement with adjacent courses of construction units, said construction unit has a height between said upper surface and said lower surface, and said upper surface and said lower surface are formed by engagement of said upper surface and said lower surface with walls of a mold from which the construction unit is slipped in a direction parallel to said walls of the mold,
- wherein said web arrangement comprises a web having, in a cross section parallel to said inner wall and said outer wall, a convex surface,
- wherein said convex surface has a first end, a second end, a first side, and a second side, said convex surface is continuously convex from said first end to said second end, and said convex surface is continuously concave from said first side to said second side in a direction generally transverse to said first and second sides.
A construction unit comprising:
- an inner wall;
- an outer wall substantially parallel to said inner wall;
- and
- a web arrangement connecting said outer wall to said inner wall,
- wherein said inner wall and said outer wall together define an upper surface and a lower surface, both said surfaces are for engagement with adjacent courses of construction units, said construction unit has a height between said upper surface and said lower surface, and said upper surface and said lower surface are formed by engagement of said upper surface and said lower surface with walls of a mold from which the construction unit is slipped to a direction parallel to said walls of the mold,
- wherein said inner wall and said outer wall each have an end surface, said web has a surface flush with at least one of said end surfaces, and the construction unit is devoid of surfaces which lie off a plane containing the flush surface of the web and which face said plane, whereby said construction unit is capable of being formed in and slipped out of a mold in a direction perpendicular to said plane.
