PROJECTED CORNER COLUMN AND DEVICE FOR APPLYING CHAMFERING WORK TO THE COLUMN

摘要

A projected corner column (A1) used at the projected corner portion of the wall surface of a building, wherein a narrow chamfered part (8) is formed at the vertical angle part (3) of the projected corner column (A1), and continuous curved surfaces (8a, 8b) but flat surfaces are formed at the narrow chamfered part (8) so that, when the projected corner column (A1) receives daylight, the same positive part and negative part as a positive part (S) and a negative part (D) produced on the surface pattern part of a plate piece (1a) can be produced. Accordingly, the chamfered part (8) at the vertical angle part (3) of the projected corner column (A1) can be made inconspicuous as much as possible, and the same shads as those (S, D) produced on the surface pattern part can be formed on the chamfered part (8). Thus, the patterns on the right and left side plate pieces (1a, 1a) can be formed continuous with each other.
