The disclosure relates to a lifting anchor for lifting a building element, such as a concrete panel, including a head part that can be attached to a lifting ring, a foot and a body interposed between the head and the foot. The body and the foot are intended to be immersed in the material of which the building element is made. The anchor extends in a main plane along a longitudinal axis. The anchor also includes at least two sub-parts, each one defining various successive portions respectively forming the head, the body and the foot of the anchor. The anchor includes at least one reinforcing piece interposed between the two flats or flat parts, extending from the head of the anchor over at least part of the foot.

Anchors, clutches, and lifting systems are described herein that increase the size of a shear cone within a precast concrete panel without using multiple clutches and without increasing the complexity of the lift system. A shear cone is the volume within the panel that the anchor and clutch pull on when orienting and positioning the precast concrete panel. Anchors described herein encompass a larger volume of the panel in different ways to produce a larger shear cone. Similarly, the clutches described herein have features that allow a clutch to accommodate the improved anchors. As a result, the anchors, clutches, and lifting systems provide a larger shear cone in the panel to increase the load capacity of the lifting system and reduce the likelihood of failure.

An insert for lifting and leveling a precast concrete slab is provided. The insert includes a sleeve that extends through the concrete slab and has two distinct threaded portions on an inner surface of the sleeve. This configuration allows a lifting bolt to be positioned into an upper end of the sleeve to lift the concrete slab, and a different-sized leveling bolt to be positioned in the sleeve to selectively elevate or raise part of the concrete slab relative to a ground surface.

A connection assembly for connecting a bolt to a slab includes a first connection part and a second connection part. The first connection part and the second connection part may be capable of being assembled to the slab in a manner so as to sandwich the slab with a first clamping member of the first connection part and a second clamping member of the second connection part between two opposite surfaces of the slab. The first connection part and the second connection part may be connected in a manner such that a connection between a first hollow-tubular-connecting-structure of the first connection part and a second hollow-tubular-connecting-structure of the second connection part may be within a through-hole in the slab, which extends between the two opposite surfaces of the slab.

A system for assembling a plurality of p re-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.

A brace insert device that is configured to be cast in concrete includes an anchor insert that has a hub with a threaded inner surface and a plurality of legs extending from the hub. A fastener has a shank portion that is threadably engaged with the threaded inner surface of the hub, where a head portion of the fastener is coupled to an end of the shank portion. A cap has an inner surface that is disposed over and conceals the head portion of the fastener. The cap is configured to be removed from a cured concrete structure to expose and allow operable access to the head portion of the fastener for use in attaching a wall brace.

A building component utilizing a pourable polyurethane or structural foam that can be used for floors, walls, and roof assemblies with a frame with an interior, back or a front, multiple partition beams forming cells in said frame, pourable polyurethane or structural foam exterior backing attached to said frame back. The structural foam is poured into said cells to a desired level, and after said structural foam is poured into said cells, said interior backing is attached to said frame front. Cabling is used to improve movability of the invention, and improve on wind loading and seismic requirements of the present invention. Safety is also improved during the manufacturing process, loading, unloading, and in final assembly through the use of cabling.

The subject invention relates to a beam-column connection structure and method of making the same wherein the beam-column connection structure includes: a precast column comprising a plurality of tension bars horizontally embedded in the precast column; a precast beam comprising a metal plate fastened to an end surface of the precast beam, the metal plate having a plurality of through holes; and a plurality of fasteners, wherein each of the fasteners respectively penetrates through each of the through holes of the metal plate and connects to an end of a corresponding tension bar so that the precast beam is fixed to the precast column.

An edge lift anchor for embedment into a concrete panel, the anchor having a head of generally plate-like form for releasable attachment with lifting equipment, and at least one leg extending from the head, for locking into the surrounding concrete, the head having an eye for receiving a locking bolt of a lifting clutch in the form of a ring clutch, the head having an upper edge engageable by the body of the ring clutch when the clutch body is inclined at the commencement of lifting a cast panel from the horizontal configuration in which it is cast to a generally vertical configuration, wherein the width of the head is such that engagement between the clutch body and the edge of the head at the commencement of lifting from a horizontal configuration is at a sufficient distance from the end of the head that any deformation of the edge of the head caused by engagement with the clutch body under the applied lifting load will be wholly contained within the width of the head.

A connector assembly, having an upper connector, a pin coupling the upper connector to a lower connector and a gusset plate sandwiched between the upper and lower connectors. Also, disclosed is a hoistable connector assembly, a lifting frame assembly, a coupling system for modular frame units, a method for assembling a module unit using the connector assembly, and a modular frame unit and building having the connector assembly.
