「産業上の利用分野」
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.
「従来の技術」
建築物の柱の構造として、鋼管の内部にコンクリートを
充填する充填鋼管コンクリート柱が知られている。これ

コンファインド効果）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 (so-called confining effect).
この構造の柱は、第５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 5, 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.

接作業が容易となる。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 to be joined to both steel pipes a, accurate positioning is required. 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. After the plates d are butted against each other, they are clamped by splints e and fixed with bolts r, 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.

かり、能率が良くないという問題があった。``Problems to be solved by the invention'' However, joining steel pipes a as described above
The trouble of attaching the plate d to the steel pipe a in advance and the splicing plate 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 the process was time consuming and inefficient.
この発明は上記の事情に鑑みてなされたらので、両鋼管

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. On the outer surface of the lower end of the steel pipe 2,
A protrusion 3 protruding outward in the radial direction of the steel pipe 2 is provided. Further, a guide pipe 4 is attached to the upper end of the steel pipe l. The guide tube 4 has an inner diameter of steel tube 1.2.
The inner surface of the lower part is made to be in close contact with the outer surface of the steel pipe l, the upper part is made to protrude upward from the upper end of the steel pipe l, and is fixed to the steel pipe l by welding etc. , into which the lower ends of the steel pipes 2 can fit. This guide tube 4 has the above-mentioned protrusion 3 provided on the steel tube 2 by notching the side surface of the guide tube 4.
A groove 5 which can be engaged with is formed along the axial direction of the guide tube 4 (that is, the axial direction of the steel tube 1.2). The above-mentioned protrusion 3 and groove 5 form both steel pipes 1 when they are engaged.
．． 2 are formed in such a position that they abut against each other in the proper direction.

る。To explain the procedure for joining the steel pipes 1.2 constructed as above, the steel pipe 2 is lifted above the steel pipe l using a crane, etc., and the axes of both steel pipes 1.2 are aligned.
Then, align the protrusion 3 of the steel pipe 2 with the groove 5 of the guide pipe 4 fixed to the steel pipe I (the state shown in Fig. 1).
, the steel pipe 2 is gradually lowered. Then, the lower end of the steel pipe 2 is inserted into the guide pipe 4, the protrusion 3 and the groove 5 are engaged, and the steel pipe 1.2 is lowered until they are butted against each other. Thereby, the steel pipe 2 is supported by the guide pipe 4 and is erected on the steel pipe 1.
その後、ガイド管４の上端内周縁と鋼管２外面とを溶接

果も奏する。In this way, according to the joining structure of the first embodiment, the steel pipe 2 can be accurately positioned simply by engaging the protrusion 3 and i+'+75. Further, since the steel pipe 2 is supported by the guide pipe 4, there is no need to use a jig for temporary fixing as in the conventional case, and therefore, the trouble of removing the jig later can be omitted, simplifying the work. . Furthermore, this guide tube 4 also has the effect of enhancing the confining effect at the joint between the steels W1 and W2.
なお、この柱Ａに曲げ耐力を負担させない場合等には、

したりすることは任意である。In addition, in cases where this column A does not bear the bending strength,
The guide pipe 4 and the steel pipe 2 are not necessarily welded,
The steel pipe 2 may simply remain inserted into the guide pipe 4. In addition, an unbonding treatment layer is provided between the steel pipe 1.2 and concrete to prevent their adhesion, and the axial deformation (shrinkage) of the steel pipe 1.2 is absorbed to prevent axial stress from occurring. , it is optional to form a deformation absorbing portion at a predetermined location of the steel pipe 1.2.
次に、第４図を参照して第２実施例を説明する。Next, a second embodiment will be described with reference to FIG.
この第２実施例では、ガイド管４の上端内周部に、上方
に向って内径か漸次大きくなるように拡径部６が形成さ

が漸次法がるように拡幅部７が形成されている。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. Further, a widened portion 7 is formed in the upper part of the groove 5 so that the width thereof gradually decreases upward.
この第２実施例では、鋼管２を鋼管１の上方から降下さ

突起３の位置がガイド管４のｉ％ｔ ５の位置と若干ず
れて（すなわち、鋼管ｌ。In this second embodiment, when the steel pipe 2 is lowered from above the steel pipe 1, even if the Lb line of the steel W2 is slightly deviated from the Ml line of the steel pipe 1, the steel pipe 2 is lowered from the enlarged diameter portion of the guide pipe 4. and is easily guided into the guide tube 4. Also, the position of the protrusion 3 of the steel pipe 2 is slightly shifted from the position of i%t5 of the guide pipe 4 (that is, the position of the protrusion 3 of the steel pipe 1).
２の向きが若干ずれている）いたとしても、突起３が溝
５の拡幅部７に案内されて、自ずと溝５に係合できる（

の突き合わせがさらに容易となる。Even if the protrusion 3 is slightly misaligned (2), the protrusion 3 is guided by the widened part 7 of the groove 5 and can automatically engage with the groove 5 (
In other words, the directions of both steel pipes are matched), so steel pipe 1.2
Matching becomes easier.
なお、上記実施例ではいずれも突起３および溝５を一組
のみ設けたが、これは複数組設けるようにしても良い。In each of the above embodiments, only one set of protrusions 3 and grooves 5 is provided, but a plurality of sets may be provided.

である。Alternatively, the projection 3 may be provided on the lower steel pipe 1, and the guide pipe 4 may be attached to the upper steel pipe 2. Furthermore, it goes without saying that the present invention is not limited to application to filled steel pipe concrete columns, but can also be applied to coated steel pipe concrete columns or steel pipe columns that do not use concrete.
