Provided is a concrete wall column external corner template device. A rectangular body is composed of two transverse standard planar large steel templates and two vertical standard planar large steel templates. The adjacent transverse standard planar large steel template and vertical standard planar large steel template are vertically connected in an abutting mode to form a T shape. A wall column external corner is formed on the inner side of each template, and the abutting portions are connected through connection rods and fastened through nuts. According to the concrete wall column external corner template device, the rectangular body composed of the four planar large steel templates is formed by vertically connecting every two standard planar large steel templates, and a concrete wall column can be formed after concrete is poured into the rectangular body. The device is simple in structure and convenient to operate, and reduces production cost by adopting the standard templates. The device joints are tight
