What is provided is a precast hollow block, a precast wall system incorporating the precast hollow block, and forms for manufacturing a hollow block and a coping cap. Accordingly, the precast hollow block and its incorporation into a precast wall system provide solutions to current “level up” block coping techniques, wall flood protection, wall force protection, and the like. Instead of having mismatched or missing face textures on sloped portions of the wall, the precast wall system allows for easier installation of face-textured blocks directly at the top of the wall. As a result, the precast wall system may readily account for slope transitions of a wall, conform to specific Department of Transportation project requirements, accommodate existing wall construction specifications, and be easily customizable for a variety of applications.

A substantially parallelepipedal construction block includes an upper face configured to be associated with the lower face(s) of one or two other similar construction block(s), a lower face configured to be associated with the upper face(s) of one or two similar construction block(s) and at least two vertical openings. The construction block also includes a front face, a rear face and two lateral faces with a recess which allows two beads to appear at the sides of the two lateral faces. The construction block is constituted by expanding foam and sand, and an insulation portion situated between the rear face and the front face. The insulation portion extends over the width of the construction block and is substantially parallelepipedal. The height and the length of the insulation portion is identical to the construction block.

A dry-stack masonry wall supported on hollow piles includes a wall having a plurality of stacked rows of masonry blocks that form a hollow interior grid of horizontal and vertical channels. The wall is supported on piles having hollow interiors, each of which is in communication with one of the vertical channels of the wall. Hardened grout filling the grid of the wall and the interiors of the piles monolithically binds the blocks into a wall which is bonded to and supported by the piles.

Building blocks for mortarless brickwork and construction of houses, buildings, structures and hardscaping items are disclosed herein. According to the first variant the building block made in a form of polygon on each vertical and each horizontal face of which the response projections and recesses are made, coming into engagement with the projections and recesses of adjacent blocks. The projections and recesses are made in truncated cone form, along the axis of which in this block intercommunicating channels are made. According to the second variant on the faces of the building block only recesses are made in it in a form of cylinders and/or truncated cones, along the axis of which in the block the channels are made. At least, in some of the indicated recesses the fastening elements in a form of discs are installed, at both sides of which along the axe the bars, fixed in the indicated channels of the adjacent blocks are fastened. The invention allows to enlarge a range of possible variants of mutual blocks fastening.

The Alphacube invention is a collection of modular shapes that form cubes, each letter of the alphabet and that are a twisty cube puzzle that can be solved for each letter of the alphabet. The pieces can both build structures and communicate verbal messages. They are a toy, puzzle, and an educational tool to teach literacy in a fun and engaging way. The pieces can also be assembled into artistic shapes or into basic shapes that describe animals and simple things like a small hole on a flat surface.

A modular wall building system includes a plurality of course modules which can be connected to form a wall such as a wall of a building structure. A course module includes inner and outer wall panels connected by upper and lower panel connectors via connector pins which are received by receiving rails extending from interior surfaces of the inner and outer wall panels. The course modules include wall course modules, bottom course modules and top course modules. Door and window modules can be installed to the building structure by attachment to the course modules. The panel connectors include structural openings for receiving vertical structural members. The wall building system includes a bottom plate structure and tie down system for attachment of the wall structure to a foundation, and a top plate structure including truss connectors for attaching a roof structure. A method of forming a wall structure is provided.

A masonry reinforcement system includes a wall structure formed from stonework including multiple stacked rows of at least one of blocks and bricks. A reinforcement mesh is disposed between a pair of the stacked rows. The reinforcement mesh includes a pair of longitudinal rails formed from rigidified fiber. A plurality of cross bars extend between and are connected to the pair of longitudinal bars, the plurality of cross bars being formed from rigidified fiber.
