【考案の詳細な説明】
本考案は、上部構造物とそれに対する基礎鋼管杭の間に
、前記基礎鋼管杭に載置溶接した状態て介在させると共
に、前記基礎鋼管杭の下端側に突曲する碗形状に構成し
た杭頭金物の構造に関する。[Detailed description of the invention] The present invention provides a structure in which a superstructure is interposed between a superstructure and a foundation steel pipe pile thereon by being placed on the foundation steel pipe pile and welded thereto, and is curved toward the lower end side of the foundation steel pipe pile. This invention relates to the structure of a pile head metal fitting configured in a bowl shape.
上記杭頭金物において、従来、肉厚を金物全体にわたる
均一なものに構成されており、上部構造物による荷重の
ために鋼管杭との溶接部分に応力集中が生じて亀裂が入
り易くなる欠点があった。Conventionally, the pile cap metal fittings mentioned above have a uniform wall thickness throughout the metal fittings, and the disadvantage is that stress concentration occurs at the welded part with the steel pipe pile due to the load from the superstructure, making it easy for cracks to form. there were.
本考案は、簡単な改造により、重量の増大を抑制しなが

行えるようにしながら上記欠点を解消することを目的と
する。The object of the present invention is to eliminate the above-mentioned drawbacks by making it possible to suppress the stress concentration while suppressing an increase in weight through simple modification, and to facilitate transportation.
次に、本考案の実施の態様を例示図に基いて説明する。Next, embodiments of the present invention will be described based on illustrative drawings.
第１図に示すように、地中に打設された基礎鋼管杭１の
下端側に突曲する碗形状に構成した抗頭金物２を、前記
鋼管杭１に載置溶接し、そして、前記杭頭金物２の上に
、コンクリート基礎３を設け、もって、構築物用基礎を
構成しである。As shown in FIG. 1, a bowl-shaped head metal fitting 2 that protrudes toward the lower end of a foundation steel pipe pile 1 driven into the ground is placed on the steel pipe pile 1 and welded. A concrete foundation 3 is provided on top of the pile head hardware 2, thereby configuring the foundation for the structure.

て、重量増大の抑制を図りながら、コンクリート基礎３
からの荷重に起因する基礎鋼管杭１との溶接部分におけ
る応力集中を抑制するように配慮しである。The pile cap hardware 2 is constructed from a portion 2a located on the axis of the basic steel pipe pile 1 by casting, cutting, press forming, or a combination thereof, as shown in FIG. The concrete foundation 3 is formed with a wall thickness that increases as it reaches the welded portion 2b to the foundation steel pipe pile 1, while suppressing weight increase.
This is to suppress stress concentration at the welded portion with the foundation steel pipe pile 1 due to the load from the base steel pipe pile 1.
前記コンクリート基礎３は、構築物本体であってもよく
、これらを上部構造物３と総称する。The concrete foundation 3 may be a building body, and these are collectively referred to as a superstructure 3.
以上要するに、本考案は、官記した杭頭金物の構造にお

大になる肉厚を備えさせである事を特徴とするから、肉
厚に変化を持たせるだけの簡単な改造を加えるだけで、
鋼管杭１との溶接部分２ｂにおける応力集中を抑制でき

強固に支持させられると共に、運搬を重量面から容易に
行えるものを安価に提供できた。In summary, the present invention provides a portion 2a located on the axis of the basic steel pipe pile 1 in the structure of the officially registered pile cap hardware.
Since it is characterized by having a wall thickness that increases from the welding portion 2b to the welding portion 2b to the foundation steel pipe pile 1, by simply making a modification to change the wall thickness,
Stress concentration at the welded part 2b with the steel pipe pile 1 can be suppressed, and the weight can be prevented from increasing as would be the case when the whole is made thicker, and the superstructure 3 can be strongly supported without being easily damaged. We were able to provide a product that was easy to transport in terms of weight and at a low cost.
