INSTALLATION STRUCTURE FOR TUBULAR STRUCTURE, AND TUBULAR STRUCTURE
To provide a tubular structure using a taper tube, which prevents stress concentration and which reduces an influence exerted on a member by environmental conditions.SOLUTION: An installation structure 1 for a tubular structure comprises a taper tube 2 that has a taper shape throughout its length, and a base 3 that includes a body part 4 and a tubular protrusion 5 protruding from the body part 4 and pressed into the side of an inner peripheral surface 2a of the taper tube 2. An outer peripheral surface 51 of the tubular protrusion 5 has a taper shape corresponding to an inner peripheral surface 2a of the taper tube 2. An outside diameter of the tubular protrusion 5 varies from a first outside diameter Dlarger than an inside diameter dof an end opening of the taper tube 2 by the taper shape of the outer peripheral surface 51 to a second outside diameter Dsmaller than the inside diameter dof the end opening.SELECTED DRAWING: Figure 1
【課題】テーパー管を用いた管構造物において、応力集中を防止し、かつ環境条件による部材への影響を低減する。【解決手段】管構造物の取り付け構造１は、全長にわたってテーパー形状を有するテーパー管２と、本体部４、および本体部４から突出してテーパー管２の内周面２ａ側に圧入される管状突出部５を含む台座３とを備える。管状突出部５の外周面５１はテーパー管２の内周面２ａに対応するテーパー形状を有し、管状突出部５の外径は外周面５１のテーパー形状によってテーパー管２の端部開口の内径ｄ１よりも大きい第１の外径Ｄ１から端部開口の内径ｄ１よりも小さい第２の外径Ｄ２まで変化する。【選択図】図１
