Title:
STRUCTURAL MEMBER, STRUCTURAL MEMBER MANUFACTURING METHOD, AND STRUCTURAL MEMBER MANUFACTURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/060483
Kind Code:
A1
Abstract:
This structural member (W1) is manufactured using a structural member manufacturing device provided with: a first clamping part (10) having a first lower clamping member (11) and a second upper clamping member (12) that are positioned so as to face each other and are capable of opening and closing; a second clamping part (20) having a third lower clamping member (21) and a fourth upper clamping member (22) that are positioned so as to face each other in correspondence with the first lower clamping member (11) and the second lower clamping member (12) and are capable of opening and closing; and a clamping-part-driving means that enables the first clamping part (10) and the second clamping part (20) to relatively separate from each other, while causing the X-axis-direction positions and the Z-axis-direction positions to correspond. Specifically, the structural member (W1) is manufactured through a structural member manufacturing method in which the first clamping part (10) and the second clamping part (20) are caused to relatively separate from each other by the clamping-part-driving means.
