Threaded rod connector including a housing having a cavity for receiving a threaded rod therein, wherein the cavity has a mouth, and an insert including a plurality of rod engagement segments, which are arranged within the cavity, wherein the cavity has a tapered zone tapering towards the mouth for wedging the rod engagement segments against the threaded rod, wherein the insert further includes a plurality of interconnected segment carrying arms, wherein each of the rod engagement segments is connected to at least one of the segment carrying arms, wherein the segment carrying arms form a cage for accommodating the threaded rod. The insert further includes a collar, wherein the segment carrying arms are interconnected via the collar, and wherein the collar surrounds a rod accommodation hole that is aligned with the cage, such that a straight threaded rod can be simultaneously positioned both within the rod accommodation hole and within the cage.

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.

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.

According to one embodiment, an insulated structure includes a frame comprising a plurality of wall studs coupled together and a plurality of foam boards attached to the frame to form a continuous insulative wall. A plurality of fasteners attaches the foam boards to the frame. Each fastener includes an elongate shaft and a cap. The elongate shaft is configured to penetrate through a foam board and into a wall stud to couple the components together. The cap is configured to be positioned atop a foam board to distribute a load relatively evenly to the foam board. A sealing tape is applied across seams between adjacent foam boards and over the fasteners' caps to seal the wall. A sealing caulk is applied to secondary fasteners and penetrations to seal the wall. In some embodiments, the structure has a fastener density of about 1 fastener per 243 in.sup.2 of foam board.
