A reinforcement system is provided to strengthen a precast concrete panel with a connector that joins the panel with another structure such as a floor joist or concrete slab. One or more hook bars can be embedded in the panel proximate to the receiving member to distribute forces from the connector to a much larger volume of the panel. To accomplish this distribution, at least one hook bar can be positioned in an anchor volume defined by anchor members of the receiving member, and at least one hook bar can be positioned outside of the anchor volume. The hook bars can be oriented with a main body portion positioned proximate to the receiving member of the connector to resist tension forces caused by a load on the connector, and end portions of the at least one hook bar encompass the larger volume of the panel.

A connector and a method of manufacturing a connector are provided for joining a precast concrete structure and a support structure such as a floor joist. An attachment member of the connector is assembled in a manner that allows forces to be transferred through a protrusion and aperture connection, which reduces the forces transferred through welded joints. As a result, the attachment member requires less welding and saves time and costs when installing the connector. In some embodiments, a support is secured to a horizontal plate which increases the rigidity of the horizontal plate and the ability of the horizontal plate to transfer forces from a support structure to a precast concrete structure.
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.

Thermally broken anchor for lifting a concrete sandwich panel
A lifting system is provided that prevents a thermal bridge between concrete layers of a precast concrete structure. In some precast concrete panels, an insulation layer is provided between concrete layers. Lifting systems of the present invention allow lifting forces from a hoisting system to be transferred to the concrete panels without creating a thermal bridge between the concrete layers, and thus, reducing the effectiveness of the insulation layer. In some embodiments, a multi-plate configuration allows a central plate to distribute a lifting force to the concrete layers and then rotate away to prevent a thermal bridge between concrete layers.

Apparatus and method for attaching signs to concrete road barriers
A mounting arrangement for securing signs at select positions along the length of a concrete barrier is provided by forming a longitudinally extending groove within one side of the barrier and slideably positioning a bolt within the channel so that the bolt is captured within the channel for longitudinal movement relative thereto and extends through the groove and to the exterior of the barrier. The bolt extends through a sign support on the exterior of the barrier. A nut engaged with the bolt draws the sign support into secure engagement with the exterior surface of the barrier.
A lifting mechanism for a concrete structure is provided through means of a void former and anchor assembly which it cast in place to provide an accurate recess in the structure having two or more spaced divergent anchors therein. The anchors define annularly aligned apertures within the recess. A lifting shackle of an arcuate configuration complimental with that of the recess is received within the recess and carries an arcuate locking bolt extendable through the aligned apertures.
A deck connector that may be cast into a structural concrete element for use in joining adjacent ones of the concrete elements to each other by the use of weld plates that are movably disposed within a weld plate housing forming an element of each of the deck connectors.
A cover for concealing an open pocket, recess or the like in a precast concrete panel following removal of a form used for positioning an anchor in the concrete panel during manufacture thereof is disclosed. The cover includes a planar or flat or substantially planar or flat top sized to cover an open pocket in a precast concrete panel, and at least one projecting member extending outward from an underside of the top of the cover. Each projecting member has two opposed end walls joined by a cross wall having a lesser height than the height of the end walls. The cross wall is positioned operatively substantially perpendicular to the two end walls of the projecting member and is operatively connected to the end walls of the projecting member. The cross wall is under compression in use and supports the end walls which have sufficient flexibility to conform to the side walls of the pocket when positioned in the pocket. In use, the cover is unconnected to any exposed anchor or other structure present in the pocket.
First and second cast-in-place concrete slabs are maintained in alignment by cutting a semi-circular groove in an edge surface of the first formed slab, positioning a flat rectangular dowel within the groove so that the dowel extends outwardly from the edge surface, and then casting the second slab against the edge surface to embed the dowel within the second slab. A gasket is engaged with the dowel to seal the groove against the intrusion of fluid concrete as the second cast-in-place. The gasket also serves to space the dowel from the groove to accommodate limited lateral movement of the dowel and groove relative to one another.
A polymeric chair having a rebar cradle and legs of a T-shaped cross-section diverging downwardly from the cradle. The outer surface portions of the legs are arcuate and define segments of a cone. Inwardly extending web portions reinforce the legs and provide feet at the distal ends of the legs disposed to the inside of the outer surface portions. A flat sand plate for the chair has radially extending slots formed therethrough which are proportioned for snug engagement with side surfaces of the feet. The slots are elongate to accommodate different sized chairs having feet spaced at varying radial dimensions. The web portions taper to optimize their reinforcing function and conserve material. In one embodiment, a ring is formed integrally with the legs intermediate the table and the distal ends of the legs. The chair is of a unitary construction and may have an integrally formed strap for extension over the cradle to secure a rebar in place.
