Plate welding-type anchor channel and method for manufacturing same

Abstract

There are provided a plate welding-type anchor channel that is buried when concrete is poured at the time of constructing a building to fix various external installations to a concrete structure later, and a method for the same. The anchor channel includes a stem plate ( 40 ) and an anchor head plate ( 50 ) that are coupled to be fixed, and can further improved anchorage performance as compared to the related art and to easily produce products of various standards. As a configuration of the plate welding-type anchor channel, a lower end ( 42 ) of the stem plate ( 40 ) of an anchor ( 30 ) is coupled to a top surface ( 24 ) of a channel ( 20 ) through welding to have a length (L 1 ) in a direction perpendicular to the top surface ( 24 ) of the channel ( 20 ). Further, the anchor head plate ( 50 ) has a predetermined length (L 2 ) and width (w 2 ), and an upper end ( 44 ) of the stem plate ( 40 ) is coupled to a bottom surface ( 52 ) through welding to be perpendicular to a length (L 1 ) direction of the stem plate ( 40 ).
