Title:
FRAME STRUCTURE
Document Type and Number:
Japanese Patent JP2019086064
Kind Code:
A
Abstract:
To construct a frame structure which has high wall strength and can be used for a simple skeleton for stretching canvas thereon such as a household garage and a temporary tent.SOLUTION: The frame structure is constructed by: arranging a plurality of pipe materials 11, respectively bent into a coplanar wave form (trapezoid or sine wave form) having constant amplitude with a straight axis as a center, in a manner that brings maximum amplitude sections 13 of neighboring pipe materials at identical positions in a longitudinal direction into contact with each other: and binding the maximum amplitude sections of neighboring pipe materials together using binders 15. The frame structure can be constructed with the pipe materials 11 subjected to three-dimensional penetrating bending method so that a frame wall face is: corrugated in a direction perpendicular to a bending direction of the coplanar wave form; or bent in an arc. Also, the frame structure can be extended longitudinally by joining edge faces of the pipe materials through pipe joints and laterally by repeating a binding procedure with the binders.SELECTED DRAWING: Figure 2
