Connector for precast concrete structures

A method of manufacturing an attachment member for joining a precast concrete structure and a support structure, comprising:

• inserting a first protrusion of a horizontal plate into an aperture of a first gusset plate;
• inserting a second protrusion of said horizontal plate into an aperture of a second gusset plate;
• welding the horizontal plate to an inner surface of said first gusset plate and to an inner surface of said second gusset plate;
• and
• welding a front edge and a back edge of a support to a bottom surface of said horizontal plate, wherein said support comprises at least one bend extending between said first and second gusset plates.

A connector for joining a precast concrete structure and a support structure, comprising:

• a receiving member having a pair of apertures extending through a body of said receiving member, wherein at least one anchor extends away from a back surface of said receiving member to hold said receiving member in a precast concrete structure;
• an attachment member, having:
• a first gusset plate and a second gusset plate each having an aperture and each having a protrusion, wherein said protrusions of said first and second gusset plates are selectively received in said pair of apertures to selectively connect said attachment member to said receiving member;
• and
• a horizontal plate extending between a first end and a second end, wherein said first end has a first protrusion that extends into said aperture of said first gusset plate, and said second end has a second protrusion that extends into said aperture of said second gusset plate, wherein said horizontal plate is configured to receive a support structure.
