ド効果）ように作用するものである。"Prior Art" A filled steel pipe concrete column, in which the inside of a steel pipe is filled with concrete, is known as a column structure for a building. This is because the vertical load on the column is mainly borne by the concrete inside the steel pipe, and the steel pipe tightens the concrete from the outside to increase the compressive strength of the concrete (the so-called confining effect).

are gradually lowered using a crane, etc., and after their ends are butted together, they are joined by welding and extended upward one by one. Since it is necessary to align the extending directions of the beams c to be joined to the respective parts, accurate positioning must be performed. For this reason, conventionally, the steel pipes a are joined together as follows. That is, as shown in FIGS. 6 and 7, temporary fixing plates d are welded and attached to predetermined locations on the outer surface of each end of the steel pipe a, and these plates d are butted together. By doing so, the position of the steel pipe a can be determined. And plate d
After abutting them together, they are clamped by splints e and fixed with bolts f, and then the abutting portions of the steel pipes a are welded. By doing so, both steel pipes a can be accurately positioned, and the steel pipes a are fixed (temporarily fixed) to each other prior to welding, making the welding work easier.

In addition, after welding steel pipes together, it is necessary to remove the plate d by fusing and polishing the welded part to make it smooth, which makes the joining process troublesome, time-consuming, and reduces efficiency. The problem was that it wasn't good.

成されている。 In the figure, reference numeral 1 indicates a steel pipe that has already been erected, and reference numeral 2 indicates a steel pipe that is joined to the upper end of the steel pipe 1. A protrusion 3 that projects outward in the radial direction of the steel pipe 2 is provided on the outer surface of the lower end portion of the steel pipe 2 . Further, a guide pipe 4 is attached to the upper end of the steel pipe 1. The guide tube 4 has an inner diameter approximately equal to the outer diameter of the steel tubes 1 and 2, and has its lower inner surface in close contact with the outer surface of the steel tube 1, and its upper portion protrudes above the upper end of the steel tube 1, and is welded. etc., and the lower end of the steel pipe 2 can fit into the upper part thereof. This guide tube 4 has a groove 5 which can be engaged with the projection 3 provided on the steel tube 2 by cutting out the side surface of the guide tube 4.
It is formed along the axial direction of the guide tube 4 (that is, the axial direction of the steel pipes 1 and 2). Protrusion 3 above
and groove 5, when these are engaged, both steel pipes 1,
2 are formed in such a position that they abut against each other in the proper direction.

１上に立設される。 To explain the procedure for joining the steel pipes 1 and 2 configured as above, use a crane or the like to lift the steel pipe 2 above the steel pipe 1, align the axes of both the steel pipes 1 and 2, and connect the protrusion 3 of the steel pipe 2. The steel pipe 2 is gradually lowered by aligning the position with the groove 5 of the guide pipe 4 fixed to the steel pipe 1 (the state shown in FIG. 1). Then, insert the lower end of the steel pipe 2 into the guide pipe 4, engage the protrusion 3 and the groove 5,
Lower the steel pipes 1 and 2 until they butt each other. Thereby, the steel pipe 2 is supported by the guide pipe 4 and is erected on the steel pipe 1.

る。 As described above, according to the joining structure of the first embodiment, the positioning of the steel pipe 2 can be determined simply by engaging the protrusion 3 and the groove 5, that is, the positioning of the steel pipe 2 in the circumferential direction and direction of the steel pipe 2 of the steel frame attached to the steel pipe 2. Positioning in the axial direction can be performed accurately. Also, steel pipe 2
Since it is supported by the guide tube 4, there is no need to use a temporary fixing jig as in the conventional case, and therefore, the trouble of removing the jig later can be omitted, simplifying the work. Furthermore, the guide tube 4 also has the effect of enhancing the confining effect at the joint between the steel pipes 1 and 2.

成したりすることは任意である。 In addition, when the bending strength is not to be imposed on the column A, the guide pipe 4 and the steel pipe 2 are not necessarily welded, and the steel pipe 2 may simply be inserted into the guide pipe 4 as it is. In addition, an unbonding treatment layer is provided between the steel pipes 1 and 2 and concrete to prevent them from adhering, and the axial deformation (shrinkage) of the steel pipes 1 and 2 is absorbed to prevent axial stress from occurring. It is optional to form deformation absorbing portions at predetermined locations of the steel pipes 1 and 2.
次に、第４図を参照して第２実施例を説明す

部７が形成されている。 Next, a second embodiment will be described with reference to FIG. In this second embodiment, an enlarged diameter portion 6 is formed at the inner peripheral portion of the upper end of the guide tube 4 so that the inner diameter thereof gradually increases upward. Furthermore, a widened portion 7 is formed in the upper part of the groove 5 so that the width thereof gradually increases upward.
この第２実施例では、鋼管２を鋼管１の上方か

５に係合できる（すなわち両鋼管の向きが合わさ
れる）から、鋼管１，２の突き合わせがさらに容
易となる。 In this second embodiment, when the steel pipe 2 is lowered from above the steel pipe 1, even if the axis of the steel pipe 2 is slightly deviated from the axis of the steel pipe 1, the steel pipe 2 is lowered into the guide pipe 1.
is easily guided into the guide part 4 by the enlarged diameter part 6 of the guide part 4. Furthermore, even if the position of the protrusion 3 of the steel pipe 2 is slightly shifted from the position of the groove 5 of the guide pipe 4 (that is, the orientation of the steel pipes 1 and 2 is slightly shifted),
Since the protrusion 3 is guided by the widened portion 7 of the groove 5 and can automatically engage with the groove 5 (that is, the directions of both steel pipes are matched), it becomes easier to butt the steel pipes 1 and 2 together.
なお、上記実施例ではいずれも突起３および溝

By simply engaging the groove formed in the guide tube, the steel frame attached to the steel pipe can be positioned simultaneously in the circumferential and axial directions, so that the steel frame faces the specified direction and is positioned at a specified height. This makes it possible to easily and accurately connect beams to steel frames. Furthermore, since no temporary fixing jig or the like is required, the joining work can be simplified.
