An anchor for supporting a load includes an anchor rod having a first threaded end portion for being embedded in a concrete structure and a second end portion for attachment to a load; a metallic wedge-shaped body attached to the first threaded end portion; and the body includes a circular cross-section, a circular top surface and a circular bottom surface joined by a side surface.

An apparatus for connecting precast elements, wherein the apparatus includes a first part adapted for being cast into a first one of the precast elements, and the apparatus further includes a second part adapted for being cast into a second one of the precast elements, wherein the first part and the second part are arranged to receive a fastener for fastening the second precast element relative to the first precast element with the fastener crossing a joint between the precast elements at an angle to the joint.

The present invention relates to a settable material aligning arrangement that allows for settable material to be aligned to a desired level before the settable material sets. It can be used for ensuring that a poured concrete floor or shotcreted wall is levelled accurately. The settable material aligning arrangement is fixed to a support base and includes a base arrangement and an aligning formation that can be fixed at varying distances from each other by a coupling arrangement.

An anchor assembly is disclosed for suspending objects to a concrete structure. The assembly includes an anchor housing having a jaw assembly therein and a opening for receiving an anchor member such as a threaded rod. The jaw assembly includes threaded rods having a threaded opening, a wood form anchor assembly and a metal decking anchor assembly. The wood form and the metal decking anchor assemblies may accommodate the anchor housing and the anchor housing is used in one of the wood form anchor assembly and the metal decking anchor assembly. The metal decking anchor assembly includes a nose-piece and the anchor housing is selectively connectable to the nose-piece via a locking connection such as a bayonet connection.

An anchor for being embedded in concrete for attachment to a fastener to support a load comprises a plug having a main body portion extending upwardly from a base portion, the plug for being attached to a form board prior to pouring of concrete, the plug having an end portion disposed a distance from the form board; and an anchor body attached to the end portion. The plug is separable from the anchor body and removable from the concrete after the concrete is cured, leaving the anchor body embedded in the concrete, the plug providing a void in the concrete after removal to provide an access opening for a threaded portion of a fastener to attach to the anchor body.

A system includes an anchor body, having a head and a hollow chamber shaft coupled to the head. The system includes a housing component configured to support the anchor body. The system also includes one or more fasteners supported by the housing component. At least one of the fasteners is coupled to the head of the anchor body, and an apex of each fastener is positioned to be above the head of the anchor body.

Shear force anchor for transmitting shear forces transversely to the longitudinal direction of a structural element within structural elements made primarily of concrete, comprising: a connection section for introducing at least one shear force into the shear force anchor which is connected to at least one load introduction section, which can be contacted to the structural element to transmit at least one force component in the direction of the shear force to be transmitted to the structural element. In order to transmit large shear forces while at the same time having a slim design of the structural element, the connection section is additionally spaced in the direction of the shear force to be transmitted from the load introduction section.

A self-supported PC column joint part. A plurality of accommodation pieces is buried in the upper surface of a lower member to which a PC column is to be joined, has accommodation spaces having open upper parts, and has female threads. A support bar is provided in a pocket formed in the lower end of the PC column, and includes a body coupled to the upper surface of the pocket to protrude and a head at the lower end of the body so as to be accommodated inside the accommodation space. A fixing piece has a through-hole formed in the center thereof such that the body of the support bar passes therethrough, and has threads formed on the outer peripheral surface thereof so as to be screw-coupled to the accommodation piece, thereby fixing the head of the support bar.
