Document Type and Number:
WIPO Patent Application WO/2023/007931
Kind Code:
A1
Abstract:
[Problem] To provide an aluminum pipe support which is lighter than an iron pipe support and has high rigidity. [Solution] An aluminum pipe support 1 comprises two pins 2A. An inner tube 3 has an outer circumferential shape of any of a regular hexagon, a regular octagon, and a regular decagon, and has a cross-sectional area, at a portion where the pins 2A are not inserted, of 1.96 times or more relative to the same portion of the inner tube of an iron pipe support of a target size. In addition, an outer tube 2 has an inner shape that allows the inner tube 3 to be inserted thereinto, and has a cross-sectional area, at a portion where the pins 2A are not inserted, of 1.35 times or more relative to the same portion of the outer tube of the iron pipe support of the target size. The upper limit on the cross-sectional area of the inner tube 3 and the outer tube 2 is set to make the total weight of the inner tube 3 and the outer tube 2 lower than the total weight of the inner tube and the outer tube of the iron pipe support of the target size. [Effect] It is possible to achieve a significant reduction in weight and increase in rigidity while satisfying a specified load capacity.
