A system for building a load bearing structure for supporting a compressive load, the system including a plurality of wooden members including: a first member including a first body having a recess therein; a second member including a second body having protrusion extending therefrom; and a third member including a third body having a recess therein; wherein the protrusion of the second member is locatable within the recess of the first or third member to interconnect the first and second or third and second members together to form the loading bearing structure, wherein the protrusion is not rotatable within the recess, and; wherein the third member has a recess with a depth greater than the height of the protrusion of the second member such that a cavity is formed between an upper inner wall of the third member and a top portion of the protrusion of the second member when the second and third members are interconnected.

A wall construction system includes multiple block types that interfit with one another to form walls in a staggered arrangement. Block types include jamb blocks having front and back surfaces, a planar surface on a first end, and a second side having a projecting surface or a receiving surface configured to mate with the projecting surface. The jamb block includes a top mating surface and a bottom mating surface configured to mate with the top mating surface. Webs extend from the front surface to the back surface to form voids. A multi-directional elevation is formed over a void adjacent the planar surface to permit stacking of blocks in two orientations. Other block types include a half jamb block having a web to form a void and a planar surface, and a web stretcher having a projecting surface on one end and a receiving surface on another end.

Precast blocks with a rectangular or quadrangular prism shape contain a normal weight hydraulic concrete casing, lightweight concrete or similar material, for building walls or slabs. The steel-reinforced blocks for walls, mezzanine or rooftop slabs have the length of the wall or slab to build. An acoustic, thermal-insulating lightweight material housed in the interior simultaneous provides for blocks sufficiently lightweight to transport and install manually on-site. For walls, the blocks are tongued and grooved on the top and bottom sides and placed horizontally one on top of the other using block or similar adhesive therebetween. In the corners or T intersections, blocks are alternatively placed and form armed headframes for stability and resistance. For blocks for slabs, the tongue and groove system is on the sides, installed one beside the other, using block or similar adhesive therebetween. Transversal rods to the slab are placed to avoid temperature retraction.

The disclosure is directed to thermal and moisture insulated interlocking brick comprising natural, in-situ carved stone faade coupled to a backing layer comprised of a massive and lightweight portions, as well as methods of forming the brick and methods for cladding and using the bricks in load bearing walls and in non-load-bearing walls (light construction).

A corner block and a building system used for constructing a building are disclosed in the present invention. The building system includes: an inner face, an outer face, an upper face having a base face and a projection protruding upward from the base face, wherein the projection extending longitudinally for the entire length of the upper face; a lower face having a complementary groove for interlocking with the projection of a cooperating interengaging building block; a first end; a second end; each of the first end and the second end has a header face, which is substantially one of a planar face, a male header face and a female header face, the male header face of the building block interlocking with the female header face of a cooperating interengaging building block; the cooperating interengaging building block is substantially similar to the building block.

A building system used for constructing a building is disclosed in the present invention. The building system includes: a first block, a corner block and a connection block interlocking with each other for constructing the building; wherein, dimensional relations between the first block, the corner block and the connection block satisfying the following conditions: Lco=L+W; Wco=1/2 L+W; Lci=L; Wci=1/2 L; Lcb=1/2 L; Wcb=W; Wherein, L is a length of the first block; W is a width of the first block; Lco is an outer length of the corner block; Wco is an outer width of the corner block; Lci is an inner length of the corner block; Wci is an inner width of the corner block; Lcb is a length of the connection block; Wcb is a width of the connection block.

A system of retaining wall blocks, a method of assembling a retaining wall block assembly, and a mold for manufacturing retaining wall blocks having adjustable engagement configurations.

A retaining wall block having a false joint and a system of retaining wall blocks. The retaining wall block includes a body having a first textured surface and a second textured surface and a false joint dividing the first and second textured surface. The false joint can have a depth divided by the width greater than two inches. The false joint can have an interior angle of less than ten degrees. The system includes a plurality of retaining wall blocks and a first course of retaining wall blocks engaged with a second course of retaining wall blocks below. Each block in the system comprising a front face having a first textured surface and a second textured surface and a false joint dividing the first and second textured surface. The false joint can extend a predetermined depth of a third surface.

A building block and a building system used for construction a building are disclosed in the present invention. The building block includes: an inner face, an outer face, an upper face having a base face and a projection protruding upward from the base face, wherein the projection extending longitudinally for the entire length of the upper face; a lower face having a complementary groove for interlocking with the projection of a cooperating interengaging building block; a first end; a second end; each of the first end and the second end has a header face, which is substantially one of a planar face, a male header face and a female header face, the male header face of the building block interlocking with the female header face of a cooperating interengaging building block; the cooperating interengaging building block is substantially similar to the building block.

A masonry block system that includes a stretcher block and a half block, each block having connector means for interlocking with an adjacent block, the blocks being constructed in a such a manner as to enable quick and easy assembly of a building structure.
