PROBLEM TO BE SOLVED: To provide a method for easily and rapidly fixing a chamfer strip and a joint bar to a form and easily detaching them from the form without damaging them when detaching them. SOLUTION: The form 80 is built up, and the lug chamfer strip 10 having punched apertures and drilled holes in a lug part 20 is held to a part to be chamfered of the inner surface of the form. While holding down the chamfer strip with one hand and holding a tacker with the other hand, a tacker pin 90 is driven into the form so that one pin part of the tacker pin 90 is put along the upper edge of the lug part and that the other pin part is put along the upper end part of the punched aperture or drilled hole 40. The lug part of the chamfer strip is thereby clamped by both pin parts and firmly fixed. When detaching the chamfer strip, one end of the chamfer strip is held and lifted. Then one pin part of the tacker pin easily comes off the form, and the chamfer strip can be easily detached from the form without damaging the chamfer strip.
