Abstract
PURPOSE: To obtain intended drilling location on flanges regardless of the bendings of section steels by supporting section steels with supporting tips without pushing upward, and by eliminating flexion of section steels due to the thrust force at time of drilling webs.
CONSTITUTION: The pushing force of a supporting tip 24 of a section steel supporting device 16 is selected so that it may not push up an H section steel 2. With the H section steel 2 fixed by side clamps 15, a piston 22 of an air-cylinder 18 progresses and the supporting tip is pushed up to contact and support the lower edge 17 of the flange directly below a vertical type drill head 13. Next, the location of the H section steel 2 is detected and the position of each drill is set to drill the web 7, both flanges 6 of the H section steel 2 with drill heads 13, 14.
