この発明は、建築物における鋼管柱の接合構造に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" This invention relates to a joint structure for steel pipe columns in buildings.

。"Prior Art" Filled steel pipe concrete columns, in which the inside of a steel pipe is filled with concrete, are known as pillar structures in buildings. 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 (so-called confining effect).
この構造の柱は、第６図に示すように、複数階（一般に
は３階程度）にわたる長さの鋼管ａを順次溶接等により
接合して立設し、その後鋼管ａ内にコンクリートを充填
することにより構築される。As shown in Figure 6, the columns of this structure are erected by sequentially joining steel pipes a that span multiple floors (generally about three floors) by welding, etc., and then filling the steel pipes a with concrete. It is constructed by

これに梁Ｃを接合するようにすることが一般的である。Then, the steel frames that will become the ends of the beams are attached to the steel pipes a in advance at predetermined positions, and after the steel pipes a are erected,
It is common to connect the beam C to this.

業が容易となる。By the way, when constructing such a column, other steel pipes a are gradually lowered from above the previously erected steel pipe a using a crane, etc., and after their ends are butted together, welding is performed. The steel pipes a are joined together and successively extended upward, but when the steel pipes a are butted together,
Since it is necessary to align the extending directions of the beams C joined to both shoulder tubes a, accurate positioning is required. For this reason, conventionally, the steel pipes a are joined together as follows. As shown in FIGS. 7 and 8, at a predetermined location on the outer surface of each end of steel pipe a,
Weld and attach the temporary fixing plate d in advance,
By butting these plates d against each other, the steel pipe a is positioned. After the plates d are butted against each other, they are clamped by splints e and fixed with bolts f, and then the butted portions of the steel pipes a are welded. By doing this, both the 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.

The trouble of attaching the plate d to the steel pipe a in advance and the temporary attachment e.
Not only does this require the work of applying the steel pipes to each other and tightening the bolts, but after welding the steel pipes together, the plate d must be removed by fusing, and the welded part must be polished to make it smooth. There was a problem that it was troublesome and time consuming and inefficient.

参照して説明する。"Means for Solving the Problem" This invention provides at least one convex portion that protrudes in the axial direction of the steel pipe at the end of one of the two steel pipes that are butted against each other and joined. At the same time, the other steel pipe is characterized in that the end thereof is formed with four parts having a shape corresponding to the above-mentioned convex part and engaging with the convex part. - "Example" Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 5.

正な向きとなって突き合わされるようになっている。First, a first embodiment will be described with reference to FIGS. 1 and 2. These figures show the joint of filled steel pipe concrete column A. Figure 1 is a perspective view showing the shape of the ends of both steel pipes to be joined, and Figure 2 shows the state in which both steel pipes are joined. It is an elevational view. In the figure, the symbol l indicates the already erected steel pipe, 2
is a steel pipe to be joined to the upper end of the steel pipe 1. A plurality of protrusions 3 are formed at equal intervals on the upper end of the steel pipe I, and four parts 4 having the same shape as the protrusions 3 are formed on the lower end of the steel pipe 2. has been done. The convex portion 3 is formed in a tapered shape so that its width gradually decreases toward the top, and accordingly, the four portions 4 are also tapered so that the width decreases toward the top. These convex portions 3 and concave portions 4 are formed at positions such that when they are engaged with each other, both steel pipes 1.2 are abutted against each other in an appropriate orientation. (Note that a recess is formed relatively between the convex parts 3, and a convex part is formed relatively between the recesses 4.) A pair of marks 5.5 for positioning is provided on the surface, and by aligning these marks 5, 5, the steel pipes 1.2 are butted against each other in the proper orientation. There is.

々に降下させる。To explain the procedure for joining the steel pipes 1.2 that have been slid together as described above, use a crane or the like to lift the steel pipe 2 above the steel pipe 1, align the axes of both steel pipes 1.2, and mark 5.5. Using this as a guide, the direction of the steel pipe 2 is roughly aligned with the direction of the steel pipe 1 (the state shown in FIG. 1), and the steel pipe 2 is gradually lowered.

される。When the steel pipe 2 descends and its recess 4 reaches the tip of the protrusion 3 of the steel pipe 1, even if there is a slight deviation in the orientation of the steel pipe 2, the sides of the protrusion 3 and the recess 4 will come into contact with each other, The subsequent descent of the steel pipe 2 is guided by the convex portion 3, and the steel pipe 2 is automatically guided in the correct direction. And once the descent of M tube 2 is completed,
The convex portion 3 and the concave portion 4 are engaged, and the steel pipe 2 is erected on the steel pipe 1.

いう手間も省くことができ、作業が簡略化される。As described above, according to the joining structure of the first embodiment, by forming the convex portion 3 and the fourth portion 4 in advance at the end of the steel pipe 1.2, the positioning of the steel pipe 2 can be performed accurately and quickly. . In addition, the steel pipe 2 is fixed to the steel pipe I by the engagement of the convex portion 3 and the concave portion 4, and there is no need to use a jig for temporary fixing as in the past, and therefore, the trouble of removing the jig later is also saved. This simplifies the work.

The steel pipes 1.2 are not necessarily welded together, and the convex portion 3 and the concave portion 4 may simply remain engaged. Also,
When welding both steel pipes 1.2, the convex part 3 and the concave part 4
It is desirable that the groove be beveled in advance. moreover,
An unbond treatment layer is provided between the steel pipe 1.2 and the concrete filled inside to prevent them from adhering,
In order to absorb deformation (shrinkage) in the axial direction of the steel pipes 1.2 and prevent the generation of axial stress, it is optional to form deformation absorbing portions at predetermined locations of the steel pipes 1.2.

In this second embodiment, a steel pipe 1.2 similar to that of the first embodiment described above is used, and a guide pipe 6 is further attached to the upper end of the steel pipe 1. The guide tube 6 has an inner diameter equal to the outer diameter of the steel pipe 1.2, has its lower inner surface in close contact with the outer surface of the steel pipe 1, and has its upper part protruded above the upper end of the steel pipe 1 for welding, etc. is fixed to the steel pipe l. An enlarged diameter portion 7 is formed at the inner peripheral portion of the upper end of the guide tube 6 so that the inner diameter thereof gradually increases upward. Further, a positioning mark 5 on the steel pipe 1 side is attached to the outer surface of the guide pipe 6.

果も奏する。In this second embodiment, when the steel pipe 2 is lowered from above the steel pipe l, even if the axis of the steel pipe 2 is slightly deviated from the axis of the steel pipe l, the steel pipe 2 is guided by the enlarged diameter portion 7I of the guide pipe 6. Since it is guided into the guide W6, Hyl and 2 can be easily matched. Furthermore, since the guide tube 6 is in close contact with the periphery of the joint from the outside, not only the steel pipes 1 and 2 are sufficiently fixed together, but also the guide tube 6 has the effect of enhancing the confining effect at the joint. .
