SLEEVE, THROUGH-HOLE STRUCTURE, AND INSTALLATION METHOD OF SLEEVE
To provide a sleeve capable of easily coping with the size of a through-hole, a through-hole structure, and an installation method of the sleeve.SOLUTION: A sleeve 20 has a peripheral wall 21 formed in a square frame shape by combining four bent members 30. Each of the four bent members 30 has a square forming part 33, a first plate part 31, and a second plate part 32. The four bent members 30 form the peripheral wall 21 by setting a tip of the first plate part 31 of one bent member 30 out of two adjacent bent members 30 to be adjacent to the tip of the second plate part 32 of the other bent member 30, and enlarge/reduce an inner space K of the peripheral wall 21 by changing a lap length of the tips of the adjacent first plate part 31 and the second plate part 32.SELECTED DRAWING: Figure 5
【課題】貫通孔のサイズに柔軟に対応できるスリーブ、貫通孔構造、及びスリーブの設置方法を提供すること。【解決手段】スリーブ２０は、四つの屈曲部材３０を組み合わせて四角枠状に構成される周壁２１を備える。四つの屈曲部材３０の各々は、角形成部３３と、第１板部３１と、第２板部３２とを有する。四つの屈曲部材３０は、隣り合う二つの屈曲部材３０のうち、一方の屈曲部材３０の第１板部３１の先端部と、他の屈曲部材３０の第２板部３２の先端部とを隣接させることにより周壁２１を構成し、かつ隣接する第１板部３１と第２板部３２の先端部同士の重合長を変更することにより周壁２１の内部空間Ｋを拡縮させる。【選択図】図５
