PURPOSE:To produce single structural member having uniform finish dimensional accuracy with high efficiency by providing a frame structure comprised of a frame for holding respective elemental part rigidly and a section for holding the elemental parts each other. CONSTITUTION:A pair of frameworks 20, 30 have approximately face symmetrical jointing face to form a holding cage C having a space surrounding a temporarily assembled work 1. Each framework 20, 30 is comprised of X-inframes 21, 31 forming the profile and sub-frames 22, 32 of desired shape stretched at the inside. The sub-frame 22 of lower framework 20 is provided with a semi- circular holding section 22a and a coarse groove holding section 22g. While the upper framework 30 is provided with semi-circular holding section 32a and groove holding section 32g at the positions corresponding with the holding sections of various shape provided at the lower sub-frame 22 side. |
