A composite foam and concrete wall includes a foam layer having a top surface, a bottom surface, a left wall surface and a right wall surface wherein the foam layer comprises at least two foam panels that define a seam that is substantially parallel to the top surface and the bottom surface. A concrete layer is secured to a surface of the foam layer.

An L-shaped shear wall module including an L-shaped outer pattern plate, an L-shaped inner pattern plate, and connectors connected between the L-shaped outer pattern plate and the L-shaped inner pattern plate. The L-shaped outer pattern plate 100 and the L-shaped inner pattern plate 200 are arranged in parallel to each other. The L-shaped inner pattern plate includes a first inner pattern plate and a second inner pattern plate which are perpendicular to each other. A corner transition block is disposed at a corner of the L-shaped inner pattern plate. The corner transition block has a protruding surface protruding towards the L-shaped outer pattern plate. The protruding surface of the corner transition block and the inner surface of the L-shaped outer pattern plate jointly enclose a concreting cavity at the corners for concreting reinforced concrete. The present application also provides a shear wall and a construction method thereof.

A building rail system. The system includes large and small building rails capable of forming flush connections at varied angles. The flush connection of the rails eliminates an extra layer of space that would otherwise exist if the rails had to be offset to form a connection.

A modular construction block comprises a masonry block shell including first and second opposing side walls, and an intermediate cross-web formed between the side walls. Each of the first and second side walls comprises first and second opposing end edges, a relatively thin wall section extending from the cross-web to the first end edge, and a relatively thick wall section extending from the cross-web to the second end edge. The relatively thick wall section of each side wall tapers from the cross-web toward the second end edge of the side wall.

A building block has opposing like outer members spaced apart by at least two risers as cross members inward from outer member ends leaving a center open with a void between the outer members and the risers. The risers extend from the bottom of the block to above the outer member tops. A continuous tongue projects upward from the top of the outer members parallel thereto along the length of the outer member and mates with grooves along the bottom of a similar outer member stackable thereon for ease of block alignment. A next stacked block is nailed to the risers projecting into its center.

An insulated concrete form (ICF) system includes a rectangular building block formed of two back to back half beam “C” sections defining a half beam space at each open end of the “” block and defining an intersecting column space orthogonal thereto with interlocking grooves on each corner side of the block. The system also includes a plurality of rectangular building blocks interlocked via the interlocking grooves configured to form a grid of beam space and intersecting column space orthogonal thereto, the resulting grid space configured to be filled with concrete and interstitial rebar to form a concrete wall.
