An apparatus for mounting construction or masonry materials to a concrete cast including an anchor. The anchor includes angled walls at the base and sidewalls terminating at an angled flange. The flange defines a gap for inserting one or more fasteners for mounting the concrete cast to another structural element with the fastener. The angled walls and flanges provide for increased load capabilities for the anchor as well as reduced bending, cracking, and shearing.

A process and form for casting a concrete light pole base having a decorative upper portion with a configuration for mounting a light pole. The form includes a base having an opening in which a resilient insert is positioned. The insert has openings for holding threaded ends of mounting bolts and for positioning wiring conduits. Ends of the bolts extend from the insert into the mold cavity. Different inserts may be used to accommodate different light pole mounting specifications. A first form section for shaping a decorative upper portion of the light pole base is positioned on the base, and forms for shaping the cylindrical lower end of the light pole base are secured above the first form section.

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 lifting anchor for a precast concrete structure is made from a single strand of metal bar stock. The anchor includes undulations or waves that ensure proper engagement of the anchor in a desired compressed concrete zone and also minimizes interference with the pre-stressed strands in the concrete structure. The anchor can be positioned in different orientations in the structures, depending on functional requirements of particular structures, and can be made from a single strand of bar stock of desired cross-sectional thickness and shape (e.g., round or square). Also, the undulations or waves in the legs of the anchor can extend in one or both directions from a plane defined by the anchor's legs.

A masonry anchor comprising an anchor member having a socket formed in one end, the socket being configured to receive and secure a mounting portion of a mounting fastener.

A lifting system for a concrete component comprises a void former incorporated into the component during casting and which provides within the component a void which receives a locking pin of a lifting anchor assembly which is locked within the void by rotation of a locking pin. The lifting anchor assembly has a visual indicator to indicate when the pin is in its locked condition within the void, and a pivotal lifting shackle of the assembly is prevented from movement into a position in which lifting can take place until the pin is in its locked condition. Preferably a base of the void former is configured to retain components of a jacking system by which a concrete slab used for road repair can be jacked into a level configuration with the remainder of the roadway when it has been positioned by use of the lifting system.

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.

There is disclosed a lifting attachment for a building unit comprising sheeting and a support structure over which the sheeting is disposed, the attachment being configured such that it can be connected to or integrated into the support structure and comprising a lifting anchor that, when the attachment is so connected or integrated, is engageable by a component for lifting the unit such that a releasable interconnection between the component and the support structure passes through an opening in the sheeting.

A prefabricated core for a building with all services already built in. The core serves as: 1. the housing for all the home's mechanical, plumbing and electrical sources, and 2. a major structural support, providing three shear walls to the structure. This invention allows access to all of the services thus allowing for ease of maintenance and avoidance of collateral damage during renovations and remodeling.

A system for assembling a plurality of pre-fabricated components to form a structure comprising: a first lifting device for transporting at least one pre-fabricated component from a source to a designated site; a second lifting device for engaging the at least one pre-fabricated component at the designated site; wherein the second lifting device comprises an engagement means to engage a portion of the at least one pre-fabricated component for installation at the designated site, and wherein the engagement means is capable of moving the engaged pre-fabricated component in at least two degrees of motion, is disclosed. In some embodiments, the engagement means comprises a plurality of locks.
