鋼管継手の補強構造の１つとして、第１図乃至
第３図に示すようなサイドガゼツト形式がある。[Detailed Description of the Invention] One of the reinforcing structures for steel pipe joints is the side gusset type shown in FIGS. 1 to 3.
前記従来のガゼツト継手構造においては第４図
及び第５図に示すように、ガゼツトプレート１を
鋼管２の板厚中心３の接線面４近傍に沿つて配設

ガゼツトに比して力の伝達が円滑に行なわれ、、
特に構面内の曲げに対しては構造的に非常に優れ
ている。 In the conventional gusset joint structure, as shown in FIGS. 4 and 5, the gusset plate 1 is disposed along the vicinity of the tangential surface 4 of the plate thickness center 3 of the steel pipe 2, and fillet welding 5 is performed. This allows for smoother power transmission compared to conventional center gazettes.
It is structurally very superior, especially when it comes to bending within the structural plane.
しかしながら前記従来のガゼツト継手構造にお
いては、ガゼツトプレート１先端部の管軸直角方
向の溶接幅ｔが狭く、この点ａに高い集中応力が
生起し、強度上の弱点になつている。 However, in the conventional gusset joint structure, the welding width t in the direction perpendicular to the tube axis at the tip of the gusset plate 1 is narrow, and a high concentrated stress occurs at this point a, which is a weak point in terms of strength.

ゼツト継手構造に係るものである。 This project was proposed to solve these problems.In the side gusset reinforcement structure of a steel pipe joint, at least the tip of the gusset plate connected to the surface of the steel pipe is fitted with a curved surface that aligns with the outer surface of the steel pipe. The present invention relates to a gusset joint structure characterized by being formed.

ものである。 In this case, at least the tip of the gusset plate in the side gusset reinforcement structure of the steel pipe joint is formed into a curved surface that matches the outer peripheral surface of the steel pipe to which the gusset plate is connected. The weld width is increased, the stress concentration at the tip of the gusset plate, which was a weak point of the conventional side gusset type, is alleviated, and a steel pipe gusset joint structure with high reliability in terms of strength can be constructed.
以下本案を図示の実施例について説明する。 The present invention will be described below with reference to illustrated embodiments.

幅t′が飛躍的に長くなり、応力集中が緩和され、
この結果鋼管継手の強度と信頼性が大幅に増大す
る。 In the embodiment shown in FIGS. 6 and 7, the side gusset plate 11 is composed of a single plate-like piece, and has a curved surface 13 that matches the outer peripheral surface of the steel pipe 12 at the joint with the steel pipe 12. The same curved surface part 1
3 is attached to the joint surface of the steel pipe 12 and fillet welded 14, and the two 11 and 12 are joined by plug welding 15 or the like. Therefore, the welding width t' at the tip of the gazette plate 11 becomes dramatically longer, stress concentration is alleviated,
This greatly increases the strength and reliability of steel pipe joints.
