管を溶接することにより行われている。(Problem to be Solved by the Invention) Column joints in which steel pipes are filled with concrete are usually constructed by applying steel pipe joints. This is done by placing a plate across the two erection pieces that protrude from the outer periphery of both sides, and welding the steel pipes together to transmit force while the plates are bolted together and temporarily secured.

ためと、鋼管の接続が溶接に依存するため上記方法は施
工性が悪く、工期の遅延を招いている。However, since the erection piece protrudes greatly from the circumferential surface of the steel pipe, it is necessary to cut off the part where it interferes with the finishing material after welding the steel pipe, which adds additional work after connection, and because the connection of the steel pipe is difficult to weld. The above method has poor workability and delays the construction period.
この発明はこの従来方法の実情を踏まえてなされたもの

管からの部材の突出をなくし、施工性の向上を図る。(Means for Solving the Problems) In the present invention, steel pipes are connected by bolts inserted between their sides, and furthermore, both joint positions have steel rods or flanges long enough to span both steel pipes. By arranging joint steel pipes, embedding them in concrete, and creating a structure that transmits force by adhesion or fixation, the protrusion of members from the steel pipes is eliminated and workability is improved.

When using this steel rod, the steel pipe on the other side is butted against the steel pipe on the top plate side, and a splint is attached to the outer periphery of both steel pipes. Both steel pipes are connected by inserting bolts between the opposing splints.
