Abstract: A fastener system for temporarily securing a reinforcing beam or the like to a poured concrete structural member includes an anchor to be set in poured concrete with an exposed handle portion free of said concrete, and a shaft with a slotted end for receiving the handle portion. A spring loaded pin in the slot retains the handle portion in interlocking engagement with the shaft. An opposite end of the shaft secures a strongback beam to the concrete structure.

Abstract: An improved anchor insert adapted to be embedded in a concrete slab for cooperation with a pick-up unit which includes a locking stem having a pair of lift shoulders extending from opposite sides of the stem, comprises a concrete-excluding hollow cage adapted to be emplaced within a form for a concrete slab for insertion of the locking stem and lift shoulders into the cage after pouring the slab, the cage including a pair of spaced apart shoulders on opposite sides of and spaced from the base of the cage, the shoulders being adapted for interengagement with the lift shoulders and also with a pair of anchor rod sections, and a pair of spaced apart anchor rod sections in such engagement, wherein the locking stem of a pick-up unit may be inserted in the cage and rotated for bringing the lift shoulders into lifting engagement with the cage shoulders, and a lifting force when imparted to the locking stem is transmitted to the anchor rod sections for lifting a slab in which the insert is embedded.

Abstract: A tilt-up wall panel in raised position is braced with panel brace assemblies, and the panel brace assemblies are braced with a pair of knee brace assemblies for each panel brace assembly, to form a tripod-like structure which eliminates the need for the conventional lateral bracing of the panel brace assemblies. The knee brace assemblies are connected to the wall panel, and for that purpose, two knee brace assemblies extending laterally between a pair of spaced apart panel brace assemblies include a connector common to both and which is connected to the wall panel. A preferred connector includes a base plate adapted to be connected to the wall panel, and a pair of swivel means mounted on one side of the base plate and each forming part of one of the latter two knee brace assemblies.

Abstract: A remotely operable mechanism for disconnecting an elevated pickup unit component of lifting apparatus from a tilt-up concrete wall slab in raised position following a lifting operation, the pickup unit being connected to the slab by fastening means engaging an insert embedded in the slab wall, includes a manipulating pole serving as an operating handle, and a flexible fastener coupling tool having a proximal end removably connected to one end of the pole and a free distal end opposite thereto, the connected pole end being uppermost on the pole in use. The tool has at its distal end a head releasably engageable with the fastening means and operable for disengaging the same from the insert to thereby release the pickup unit for removal from the wall slab. The tool includes a universal joint extending between and flexibly coupling the head and the proximal end of the tool, whereby the tool may be rotated by rotation of the pole while the pole is angularly disposed relative to the axis of rotation of the head.

Abstract: An improved anchor insert adapted to be embedded in a concrete slab for cooperation with a pick-up unit which includes a locking stem having a pair of lift shoulders extending from opposite sides of the stem, comprises a concrete-excluding cage having a hollow body and a base closing the lower end of the body, a first pair of spaced apart anchor rod sections intersecting the body for the application of a lifting force thereto by the lift shoulders inserted in the cage, a second pair of spaced apart anchor rod sections extending transversely of the first pair of anchor rod sections and fixedly secured thereto on opposite sides of the cage body, a pair of foot members disposed beneath each anchor rod section of the second pair, the anchor rod sections of the second pair being seated thereon, the foot members in each pair being disposed on opposite sides of the cage and spaced outwardly therefrom, and the foot members being adapted to seat on the floor of a slab form to space the anchor rod sections of both pair
