とを特徴とするものである。(Means for Solving the Problems) In order to achieve the above object, in the structure of the column base of the steel pipe column according to the present invention, a predetermined amount of reinforcing bars are arranged around the outer periphery of the steel pipe column,
At the base of a steel pipe column made by pouring and hardening concrete, a predetermined rib-like protrusion is formed on the outer surface of the steel pipe column at the manufacturing stage to smoothly transfer stress from the steel pipe column to the concrete and further to the reinforcing steel. It is characterized by being constructed so that it can be transmitted to the user.
（実施例） 以下、本発明の好適な実施例を図面により説明する。(Example) Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
第１図及び第２図は本発明の一実施例を示す柱脚部の要

の外周に配設された鉄筋、１２はコンクリートである。1 and 2 are cross-sectional views of essential parts of a column base showing an embodiment of the present invention, in which 10 is a steel pipe column of the column base, 11 is a reinforcing bar disposed on the outer periphery of the column, and 12 is a steel pipe column of the column base. is concrete.
しかして、本実施例では、該鋼管柱１０の外表面に工場
での製作段階で所定のリブ１３が一体に突出形成されて
いる。Therefore, in this embodiment, predetermined ribs 13 are integrally formed to project from the outer surface of the steel pipe column 10 at the manufacturing stage in a factory.
本実施例では鋼管柱１０は、いわゆる縞鋼板を使用して
成形されており、第２図に示すように該縞鋼板１４の表
面に突出形成された各リブ１３が外表面側になるように
設定されてなるものである。In this embodiment, the steel pipe column 10 is formed using a so-called striped steel plate, and as shown in FIG. It is something that is set.

有効かつ円滑に伝達することができる。In this embodiment having such a configuration, the steel pipe column 10 is formed using a striped steel plate 14 on which ribs 13 are integrally formed in advance at the factory manufacturing stage, and each rib 1
3, the stress transmitted from the upper structure to the steel pipe column 10 of the column base can be effectively and smoothly transmitted to the concrete 12 and further to the reinforcing bars 11.
また、現場でのリブ１３の形成作業は不要であり、従来
例におけるスタッドボルトの打設作業等が省略可能で、
施工性が向上する。In addition, there is no need to form the ribs 13 on-site, and the work of driving stud bolts in the conventional example can be omitted.
Improves workability.
さらに、リブ１３は、鋼管柱１０の外周面全面に亘って
均等に形成されているため、応力伝達が一部に集中する
ことがなく、無理なく行なうことが可能となるものであ
る。Furthermore, since the ribs 13 are uniformly formed over the entire outer circumferential surface of the steel pipe column 10, the stress transmission is not concentrated in one part and can be carried out without difficulty.
なお、本発明は上記実施例に限定されるものではなく、
リブ１３は上記縞鋼板を利用する以外にも適宜選択可能
である等、本発明の要旨を逸脱しない範囲内で種々の変
形例が可能なことは言うまでもない。Note that the present invention is not limited to the above embodiments,
It goes without saying that various modifications are possible without departing from the spirit of the present invention, such as the ribs 13 being able to be appropriately selected other than using the above-mentioned striped steel plate.
