Abstract
Adjacent concrete wall panels are connected at the vertical joint by a shear connector structure that includes a metal connector angle embedded in a corner portion of one of the panels, and one or more threaded nuts or studs are welded to a flange of the angle. A metal shear connector plate has a hole for each threaded nut or stud and elongated holes or slots for the other concrete panel. After the panels are erected and positioned, the connector plate is bolted to the studs and self-tapping concrete anchor screws are inserted into the slots and threaded into holes formed in the other panel. The studs are formed by machinery weld studs to form a bore with threads at the welded end of each stud.
Claims9
A shear connector structure for connecting a first concrete panel and a second concrete panel in adjacent relation after the panels are set vertically on a concrete support for a building, the shear connector structure comprising
- a right angle metal connector member embedded in a corner portion of the first concrete panel,
- a generally flat metal shear connector plate overlapping a joint between the adjacent first concrete panel and the second concrete panel,
- at least one threaded fastener securing the shear connector plate to the metal connector member, and
- at least one self-tapping concrete anchor screw extending through at least one hole within the shear connector plate and into at least one drilled hole within the second concrete panel and securing the shear connector plate to the second concrete panel.
A shear connector structure for connecting a first concrete panel and a second concrete panel in adjacent relation after the panels are positioned vertically on a concrete support for a building, the shear connector structure comprising
- a generally flat metal shear connector plate overlapping a joint between the adjacent first concrete panel and the second concrete panel,
- the metal shear connector plate having spaced holes for each of the first concrete panel and the second concrete panel,
- each of the holes within the metal shear connector plate for the second concrete panel being elongated to define a slot,
- at least one threaded fastener for each hole within the metal shear connector plate and the corresponding hole within the first concrete panel,
- each threaded fastener within the first concrete panel comprises a weld stud having an end portion with internal threads and with the end portion welded to the metal shear connector plate, and
- a self-tapping concrete anchor screw extending through each of the slots within the shear connector plate and into a corresponding hole within the second concrete panel and securing the metal shear connector plate to the second concrete panel.
