A lifting anchor assembly that is configured to be embedded in a tilt-up concrete structure includes an anchor member that has a pair of legs extending downward from a central portion of the anchor member to form a generally inverted U shape. A spacer is disposed at a lower end portion of each of the pair of legs, where the spacers each include a plurality of spacing arms that extend radially at different lengths from an engagement portion of the spacer that adjustably attaches at the anchor member. The engagement portion of the spacer is configured to engage the anchor member in different rotational positions to selectively position one of the plurality of spacing arms in a downward position for accommodating different thickness dimensions of concrete structures.

A structural wall unit system includes a plurality of wall units having at least one face being a rotational tessellation. The face has at least two irregular sides extending therefrom. Each side of the wall units have at least one spacer or connector configured to engage other wall units. The structural wall unit system also includes a plurality of starter course units, where each starter course unit has a portion of a primary rotational tessellation element having at least one irregularly shaped side that is an image of the first side or the third side. Each irregularly shaped side of the starter course units have at least one spacer or connector configured to engage the wall units, and the starter course units have at least one straight side. The starter course units and the wall units are configured for assembly as a structural wall having a natural, random appearance.

The invention comprises a product. The product comprises a foam insulating panel, the panel having a first primary surface and an opposite second primary surface, wherein the foam insulating panel defines at least one recessed channel in the first primary surface, the at least one recessed channel being sized and shaped to provide a mold for a structural reinforcing member. The product also comprises a concrete panel formed on the first primary surface and filling the at least one recessed channel so as to provide a structural reinforcing member for the concrete panel. The product further comprises an elongate anchor member in the foam insulating panel and extending from the first primary surface of the foam insulating panel into the concrete panel. A method of making a composite reinforced insulated concrete structure is also disclosed.

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 pit for containing a vehicle lifting apparatus is constructed from a plurality of precast concrete pieces and assembled in a trench. Conduit, plumbing, heating elements, and the like are cast into the pieces to facilitate safe construction/assembly of the pit. A lift apparatus is assembled or positioned in and at least partly attached to the pit. One or more mounting features are cast into and/or attached to the pit wall to help fix the lifting apparatus relative to the pit and/or to help fix the pit relative to a surrounding building.

An apparatus, such as a beam pocket, connects a beam to a wall, such as a concrete wall. The apparatus includes a frame having a plurality of panels that cooperate to define a pocket of various heights. The apparatus includes a clamp within the pocket. The clamp is configured to secure an end of the beam at a position within the pocket. The clamp is further configured to selectively define the position relative to the frame. The apparatus further includes at least one anchor extending from the clamp and away from the pocket for mounting with the wall.

An oval cover member is formed of high density polyethylene and sized to cover a pocket in which a lift member is secured to a pre-cast concrete structural member. The cover member can be secured to the lift member by a cable tie threaded through the opening of a first protrusion, back through a smaller opening in a second protrusion and pulled to draw the cover member tightly against the concrete structural member. The opposing protrusions form a valley therebetween for the positioning of the lift member. The size of the smaller opening in the second protrusion is too small for the passage of the head of the cable tie, enabling the cover member to be tightly secured to the lift member. A peripheral channel in the cover member can receive a gasket or adhesive that can seal the cover member against the surface of the concrete structural member.
