A retaining wall having a plurality of courses of retaining wall blocks including a first upper course and a second lower course. Each retaining wall block has opposed front and rear faces, opposed first and second side surfaces, and opposed and substantially parallel upper and lower surfaces, and at least one weight bearing pad extends from one of the upper and lower surfaces. The at least one weight bearing pad extends substantially from the rear face to the front face of the block. The weight bearing pads are the only areas of contact between the blocks in the first upper course and the blocks in the second lower course.

A pre-stressed concrete box culvert includes a three-sided culvert top section having a pre-stressed top slab, a first sidewall and a second sidewall. The first and the second sidewalls extend orthogonally from opposite ends of the pre-stressed top slab, and the first and the second sidewalls each include a free end that has at least one male or female connector. The pre-stressed concrete box culvert includes a three-sided culvert bottom section having a pre-stressed bottom slab and a third sidewall and a fourth sidewall. The third and the fourth sidewalls extend orthogonally from opposite ends of the pre-stressed bottom slab, and the third and the fourth sidewalls each include a free end that has at least one male or female connector to mate with the at least one corresponding male or female connector arranged at one of the respective free ends of the first and the second sidewalls.

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 retaining wall having a plurality of courses of retaining wall blocks including a first upper course and a second lower course. Each retaining wall block has opposed front and rear faces, opposed first and second side surfaces, and opposed and substantially parallel upper and lower surfaces, and at least one weight bearing pad extends from one of the upper and lower surfaces. The at least one weight bearing pad extends substantially from the rear face to the front face of the block. The weight bearing pads are the only areas of contact between the blocks in the first upper course and the blocks in the second lower course.

An interlocking construction block system comprising a family of blocks that interlock along three axes, including a left/right axis, a front/back axis, and an up/down axis. The family of blocks are self-aligning and do not require skilled labor or mortar to create a structure of any length, width, height, or shape. Each block comprises a specific geometry that allows all blocks in the family to interlock in a woven pattern that not only locks the blocks in place but also allows even distribution of structural weights and stresses. The disclosed blocks can be manufactured in different sizes to conform to any building code requirement and to create wall lengths to a one-inch measurement. The blocks may comprise channel openings to allow for plumbing, electrical, and structural reinforcements in the structure and may each be reinforced with an internal mesh cage.

Apparatuses and methods associated with creating a form to construct a concrete structure (e.g., a concrete building). In embodiments, an apparatus may comprise a number of forming system components, including but are not limited to a plurality of fixed or adjustable posts; a plurality of fixed or adjustable roof struts, a plurality of fixed or extensible frames; and/or a plurality of mounts. The fixed/adjustable posts, the fixed/adjustable roof struts, and the fixed/extensible frames are selectively and adjustably coupled together to create a form of selected dimensions to construct the concrete structure/building on site with reduced number of pours, e.g., a single pour. Other embodiments may be disclosed or claimed.

A mold assembly and method for molding two concrete blocks in face-to-face non-contacting relationship forms blocks having smooth front faces. The mold assembly includes a mold box having two mold cavities configured to form two blocks in face-to-face non-contacting relationship. A common partition plate separates the two mold cavities and opposite sides of the partition plate form the smooth front faces of the blocks. The two mold cavities are each configured to form a block having a raised front face with a beveled edge around its entire perimeter and a border around the entire perimeter of the beveled edge. The portions of the border at the top and the sides of the raised front face are curved and the portion of the border at the bottom of the raised front face is straight. A core bar is slidably inserted into the mold box beneath the bottom of the partition plate, and opposite sides of the core bar extend into and form the front bottom portions of the mold cavities.

An interlocking construction block system comprising a family of blocks that interlock along three axes, including a left/right axis, a front/back axis, and an up/down axis. The family of blocks are self-aligning and do not require skilled labor or mortar to create a structure of any length, width, height, or shape. Each block comprises a specific geometry that allows all blocks in the family to interlock in a woven pattern that not only locks the blocks in place but also allows even distribution of structural weights and stresses. The disclosed blocks can be manufactured in different sizes to conform to any building code requirement and to create wall lengths to a one-inch measurement. The blocks may comprise channel openings to allow for plumbing, electrical, and structural reinforcements in the structure and may each be reinforced with an internal mesh cage.

A mold set for manufacturing interlocking construction blocks comprising a modular family molds and connecting side walls. The molds may be configured to create assembled female molds that may be filled with fluid cement, which can be removed from the female molds with corresponding male molds. Each assembled female mold may comprise one or more interlocking sections that allow the resulting blocks to interlock in three directions along three axes, including a left/right axis, a front/back axis, and an up/down axis. Each block comprises a specific geometry that allows all blocks in the family to interlock in a woven pattern that not only locks the blocks in place but also allows even distribution of structural weights. The disclosed modular mold sets allow blocks to be manufactured in different sizes to conform to any building code requirement and to create wall lengths to a one-inch measurement.
