Concrete coupling assembly comprises a base holder for being attached to a concrete forming surface, the base holder including a central opening; a coupler having one end disposed within the central opening, the coupler having an axis for being positioned substantially transverse to the forming surface, the coupler having first and second threaded bores through the one end for attachment of a threaded rod; and a separate anchor body threadedly attached to another end of the coupler.

An anchor particularly adapted to be embedded into a concrete construction for suspension of a ceiling panel, duct or the like, includes a base which receives inserts that have an axial threaded bore. The base is open at its lower end and can receive a threaded rod by virtue of ratcheting inserts received within the base. The inserts and base are particularly shaped to prevent jam and ease of insertion of the rod in the anchor. The anchor also has a head flange that sits above a plurality of fasteners secured to the anchor which is used to simultaneously drive the fasteners into a form for the concrete member. The fasteners are connected to the anchor extending in generally parallel and spaced relation to the anchor. The fasteners can be held by a support or sleeve-like holder which surrounds at least a portion of the base of the anchor or they can be attached to the base of the anchor. The fasteners project downwardly through the bottom of the anchor for driving into the form board.

A modular panel system including a plurality of posts where each post includes a front face, a rear face, and opposed lateral faces. A central channel is formed in the front face where the central channel has a linking opening, a first ledge and a second ledge. Cutouts are formed in the ledges. The rear face includes a panel receiving channel that receives an edge of a panel. A linking element is configured to be secured in the linking opening. The head of the linking element is sized to fit within the first and the second cutouts and be secured by the first and second ledges to couple the first post to the second post. The lateral faces of the coupled posts together form a first side central channel and a first side central channel cutout that is configured to receive a second linking element to couple a third post to the coupled first and second posts.

The invention teaches a technology to connect attachments with building structures using a connector pad. The connector pad invented for this purpose allows the compensation of construction tolerances and strengthening of the building structure at the connection point.
