INSTALLATION STRUCTURE FOR TUBULAR STRUCTURE, AND TUBULAR STRUCTURE
To prevent stress concentration and reduce an influence of environmental conditions, in a tubular structure using a taper tube in which a tube enlargement part assuming a taper shape is formed at an end.SOLUTION: An installation structure for a tubular structure comprises a tube member that includes a tapered tube enlargement part formed in a predetermined-length section including at least one end and a straight part formed in a section except the predetermined-length section, and a base that includes a body part and a tubular protrusion protruding from the body part and pressed into the side of an inner peripheral surface of the tube enlargement part. An outer peripheral surface of the tubular protrusion has a taper shape corresponding to an inner peripheral surface of the tube enlargement part. An outside diameter of the tubular protrusion varies from a first outside diameter larger than an inside diameter of an end opening of the tube enlargement part to a second outside diameter smaller than the inside diameter of the end opening, in accordance with the taper shape of the outer peripheral surface.SELECTED DRAWING: Figure 1
【課題】端部にテーパー形状の拡管部が形成された管部材が用いられた管構造物において、応力集中を防止し、かつ環境条件の影響を低減する。【解決手段】管構造物の取り付け構造は、少なくとも一方の端部を含む所定長さの区間に形成されるテーパー形状の拡管部、および所定長さの区間以外の区間に形成されるストレート部を含む管部材と、本体部、および本体部から突出して拡管部の内周面側に圧入される管状突出部を含む台座とを備える。管状突出部の外周面は拡管部の内周面に対応するテーパー形状を有し、管状突出部の外径は外周面のテーパー形状によって拡管部の端部開口の内径よりも大きい第１の外径から端部開口の内径よりも小さい第２の外径まで変化する。【選択図】図１
