A construction block and a wall face structure with high durability and versatility are provided. The construction block including: a front face wall and a rear face wall being parallel to each other; a top face wall with a horizontal groove formed for inserting a horizontal reinforcement; side face walls formed with at least one vertical groove for inserting a vertical reinforcement; at least one vertical hole formed between both of the side face walls and closed off by the top face wall and opened at a bottom face; a plurality of protrusions formed on the bottom face in a shape to engage with the horizontal groove; and recessed slits respectively formed in vertical direction on each side face of the front face wall and the rear face wall, is used.

Embodiments of modular building units (blocks) are disclosed that can be stacked to provide insulating concrete forms (ICFs). The blocks are formed of a foamed polymer material, such as foamed polyurethane. The blocks, when assembled together in an ICF, are configured to form one or more vertical columns of concrete and one or more horizontal beams of concrete intersecting the one or more columns, in a manner of post and beam construction. The blocks can be tightly interlocked with other blocks in a construction process. The disclosed blocks can include significant interior space for rebar and concrete to be inserted to construct the structure. Molds and methods for producing modular units are also disclosed. The molds and methods enable rapid production and removal of modular building units from the molds. Methods of constructing structures using the modular building units are also disclosed.

A dovetailed building block includes a block body having a plurality of side surfaces. The side surfaces are constructed in an order of having a side surface with a dovetailed recess next to another surface with a dovetailed projection. The dovetailed projection of one said block body can engage the corresponding dovetailed recess of another said block body in a 90-degree cross manner. Thereupon, while in stacking a plurality of the block bodies, variety of secured and stable three-dimensional curved configuration can be built through angular engagement of one dovetailed projection of one block body and another dovetailed recess of another block body.

A masonry wall is formed of masonry block units abutted with one another in series within stacked rows. Each masonry block unit is a concrete body having two opposing exterior side walls defining respective portions of the assembly masonry wall. Vertical reinforcement channels are formed in the exterior side walls of each masonry block unit so as to be open laterally to the exterior. The reinforcement channels align with corresponding channels in the masonry block units in adjacent stacked rows to receive elongate reinforcement members, for example rebar, inserted laterally therein from the exterior surface of the assembly masonry wall. A bonding material can then be recessed laterally into the reinforcement channels so as to bond the reinforcement members to the masonry assembly.

The present invention includes a method and a unit for a masonry wall system, each unit comprising a face shell wherein the interior surface has a transverse axis running from the top surface to the bottom surface of the face shell, and one or more webs having a front end and a rear end, wherein the rear end of each web is integral with or attached to the interior surface of the face shell along the transverse axis. The method for wall construction further comprising positioning one or more vertical reinforcement rods or tendons with one end embedded in a wall-foundation and laying a layer wall units on the wall-foundation such that the one or more webs of the layers of wall units are aligned, and the vertical reinforcement rods or tendons run through or are adjacent to the webs of the wall units.

This is a new construction system for a one-or two-story house, through the use of a new generation of highly productive concrete blocks, which work off each other to simplify the construction process; reducing construction time by more than 50% compared to the traditional system, saving more than 50% of mortar used in setting the blocks. The pillar blocks, foundation beams and rafters completely eliminate the use of a wooden formwork or metal formwork. These are multifunctional blocks, which complement each other, to generate high productivity, construction speed and resistance. They contain lateral protrusions that can be placed through simple hand pressure, helped by steel clips, on which the sheetrock panels are installed, thus avoiding the use of Steel Frames. The savings gained from not using the Steel frame is a very new invention and is a great reduction in the cost and time of constructing houses.
