Description

本発明は、コンクリート製の複数の柱体を接続する継手管、これを備えた組立式コンクリート柱、および組立式コンクリート柱の組立方法に関する。 The present invention relates to a joint pipe for connecting a plurality of concrete columns, an assembly-type concrete column provided with the joint pipe, and a method for assembling the assembly-type concrete column.

従来、コンクリート製の複数の柱体を接続して１本のコンクリート柱として組み立てて使用する場合において、上柱の下端部と下柱の上端部を突き合わせ状態で連続するテーパ形状とし、ここにテーパ状の継手用鋼管を嵌着するもの（例えば、特許文献１参照）、上柱の下端部に継手用鋼管を一体化して設け、この継手用鋼管を下柱の上端部のテーパ部に嵌着するもの（例えば、特許文献２及び３参照）、および、上柱および下柱の向かい合う端部に組み合わせ形状を設け、その周囲を鋼管で補強するもの（例えば、特許文献４および５参照）がそれぞれ知られている。 Conventionally, when a plurality of columns made of concrete are connected and assembled as one concrete column for use, the lower end of the upper column and the upper end of the lower column are formed into a continuous tapered shape in a butt state, and the taper is provided here. A steel pipe for joints is fitted in a shape (see, for example, Patent Document 1), a steel pipe for joints is integrally provided at the lower end of the upper column, and the steel pipe for joints is fitted to the tapered portion at the upper end of the lower column.

上記の特許文献１の構成では、継手構造がシンプルであるものの、継手用鋼管は上柱下端部および下柱上端部のテーパ形状と略同一のテーパ形状に形成する必要があるため、量産することが難しく、価格も高価である。また、継手用鋼管がテーパ状であるため、この継手用鋼管を上柱の下端部に取り付けるには、継手用鋼管を上柱の上端から嵌装し、上柱の下端部までスライド移動させなければならない。その際にクレーンなどによる上柱の上げ下げが必要である。 In the configuration of Patent Document 1 described above, although the joint structure is simple, the steel pipe for the joint needs to be formed into a tapered shape substantially the same as the tapered shape of the lower end of the upper column and the upper end of the lower column. Is difficult and the price is high. In addition, since the steel pipe for joints is tapered, in order to attach this steel pipe for joints to the lower end of the upper column, the steel pipe for joints must be fitted from the upper end of the upper column and slid to the lower end of the upper column. Must be. At that time, it is necessary to raise and lower the upper pillar with a crane or the like.

また、上記の特許文献２および特許文献３の構成では、継手用鋼管を上柱の下端部に一体化に設ける必要があるため、継手用鋼管の内部に設けた座板にプレストレスを加えるために配置された鋼材を係止し緊張するなど、上柱の生産工程が複雑である。また、継手用鋼管および下柱上端部のテーパ部の寸法精度から、組立後のコンクリート柱の高さが製品毎に異なることがある。 Further, in the configurations of Patent Documents 2 and 3 described above, since it is necessary to integrally provide the steel pipe for the joint at the lower end of the upper column, prestress is applied to the seat plate provided inside the steel pipe for the joint. The production process of the upper pillar is complicated, such as locking the steel materials placed in the above and tensioning them. In addition, the height of the concrete column after assembly may differ from product to product due to the dimensional accuracy of the steel pipe for joints and the tapered portion at the upper end of the lower column.

さらに、上記の特許文献４および特許文献５の構成では、上柱下端部と下柱上端部に互いが組み合わさるような形状を形成する必要があるため、上柱および下柱を成形するための型枠の形状が複雑で高価である。 Further, in the above-mentioned configurations of Patent Document 4 and Patent Document 5, since it is necessary to form a shape in which the lower end portion of the upper pillar and the upper end portion of the lower pillar are combined with each other, it is necessary to form the upper pillar and the lower pillar. The shape of the formwork is complicated and expensive.

このように、複数の柱体を接続する継手部において、継手部により接続される柱体の端部に特別な加工の必要がなく、かつ、容易に接続できるものが求められている。 As described above, in the joint portion connecting the plurality of pillars, there is a demand for a joint portion that does not require special processing and can be easily connected to the end portion of the pillar body connected by the joint portion.

次に、第１の実施の形態の組立式コンクリート柱１の組立方法を説明する。 Next, a method of assembling the assembling type concrete column 1 of the first embodiment will be described.

組立式コンクリート柱１は、上記の継手管４を用い、一の柱体２の端部および他の柱体３の一および他の挿入部６，７と、継手管４の継手管本体部10の一端側（一の被挿入部12）の内部および他端側（他の被挿入部13）の内部と、の間に一の抜止部22となる一のスペーサＳ1および他の抜止部23となる他のスペーサＳ2を介在させることにより一の柱体２と他の柱体３とを接続して組み立てる。 The assembly type concrete column 1 uses the above-mentioned joint pipe 4, the end portion of one pillar body 2, one of the other pillar bodies 3 and other insertion portions 6 and 7, and the joint pipe main body portion 10 of the joint pipe 4. With one spacer S1 and another retaining portion 23, which are one retaining portion 22 between the inside of one end side (one inserted portion 12) and the inside of the other end side (other inserted portion 13). One pillar 2 and the other pillar 3 are connected and assembled by interposing another spacer S2.

本実施の形態においては、まず、図２（ａ）に示すように、予め成形された一の柱体２を設置部Ｇに設置する。 In the present embodiment, first, as shown in FIG. 2A, one preformed pillar 2 is installed in the installation portion G.

次いで、図２（ｂ）に示すように、一の柱体２の一の挿入部６に一のスペーサＳ1を取り付ける。一のスペーサＳ1は、接着剤などにより一の柱体２の一の挿入部６に固定されてもよい。また、一のスペーサＳ1の外周側に接着剤などが塗布されてもよい。 Next, as shown in FIG. 2B, one spacer S1 is attached to one insertion portion 6 of one prism 2. The spacer S1 may be fixed to the insertion portion 6 of the pillar 2 by an adhesive or the like. Further, an adhesive or the like may be applied to the outer peripheral side of one spacer S1.

さらに、一のスペーサＳ1を取り付けた一の柱体２の一の挿入部６を、図２（ｃ）に示すように、別途予め形成された継手管４の継手管本体部10の一の被挿入部12に嵌挿する。このとき、一の柱体２を継手管４の継手管本体部10に嵌挿する長さ、すなわち一の挿入部６の軸方向の長さは、一の柱体２の外径の１．５倍以上とする。 Further, as shown in FIG. 2C, the insertion portion 6 of the one pillar body 2 to which the one spacer S1 is attached is covered with one of the joint pipe main body 10 of the joint pipe 4 separately formed in advance. It is inserted into the insertion portion 12. At this time, the length of fitting the one pillar 2 into the joint pipe main body 10 of the joint pipe 4, that is, the axial length of the one insertion portion 6 is 1. Make it 5 times or more.

次いで、図２（ｄ）に示すように、予め成形された他の柱体３の他の挿入部７に他のスペーサＳ2を取り付ける。他のスペーサＳ2は、接着剤などにより他の柱体３の他の挿入部７に固定されてもよい。また、他のスペーサＳ2の外周側に接着剤などが塗布されてもよい。 Next, as shown in FIG. 2D, the other spacer S2 is attached to the other insertion portion 7 of the other preformed prism 3. The other spacer S2 may be fixed to another insertion portion 7 of the other pillar 3 by an adhesive or the like. Further, an adhesive or the like may be applied to the outer peripheral side of the other spacer S2.

そして、他のスペーサＳ2を取り付けた他の柱体３の他の挿入部７を、図２（ｅ）に示すように、継手管４の継手管本体部10の他の被挿入部13に上方から嵌挿する。このとき、他の柱体３を継手管４の継手管本体部10に嵌挿する長さ、すなわち他の挿入部７の軸方向の長さは、他の柱体３の外径の１．５倍以上とする。 Then, as shown in FIG. 2 (e), the other insertion portion 7 of the other pillar body 3 to which the other spacer S2 is attached is moved upward to the other insertion portion 13 of the joint pipe main body portion 10 of the joint pipe 4. Insert from. At this time, the length of inserting the other pillar 3 into the joint pipe main body 10 of the joint pipe 4, that is, the axial length of the other insertion portion 7 is 1. Make it 5 times or more.

この結果、一の柱体２と他の柱体３とが継手管４を介して接続され、組立式コンクリート柱１が組み立てられる。 As a result, one column 2 and the other column 3 are connected via the joint pipe 4, and the assembly type concrete column 1 is assembled.

このように、第１の実施の形態によれば、継手管４は、継手管本体部10の内径が座板部11に対して一端側と他端側とでそれぞれ略一定となっているので、継手管本体部10をストレート管で構成し、座板部11を平板で構成できる。そのため、継手管本体部10および座板部11にそれぞれ規格品を使用することができるので、継手管４の量産が容易であり、安価に製造できる。 As described above, according to the first embodiment, in the joint pipe 4, the inner diameter of the joint pipe main body 10 is substantially constant on one end side and the other end side with respect to the seat plate portion 11. , The joint pipe main body 10 can be made of a straight pipe, and the seat plate 11 can be made of a flat plate. Therefore, standard products can be used for the joint pipe main body portion 10 and the seat plate portion 11, respectively, so that the joint pipe 4 can be easily mass-produced and can be manufactured at low cost.

また、一の柱体２と他の柱体３とは、端部である一および他の挿入部６，７を継手管４に挿入することによって容易に接続できるため、端部に特別な加工を必要とせず、一般的なコンクリート柱の生産工程で容易に製造した一の柱体２および他の柱体３を使用できる。 Further, since one prism 2 and the other prism 3 can be easily connected by inserting the one and the other insertion portions 6 and 7 which are the ends into the joint pipe 4, special processing is performed on the ends. One pillar 2 and another pillar 3 easily manufactured in a general concrete pillar production process can be used without the need for.

さらに、一および他の柱体２，３の一および他の挿入部６，７の位置が座板部11により規制されるので、組立式コンクリート柱１の製品毎に高さがばらつきにくい。 Further, since the positions of one of the one and the other pillars 2 and 3 and the other insertion portions 6 and 7 are regulated by the seat plate portion 11, the height of the assembled concrete pillar 1 is unlikely to vary from product to product.

また、継手管本体部10の座板部11に対して一端側（一の被挿入部12）と他端側（他の被挿入部13）との内径が略同一であるため、一および他の柱体２，３の一および他の挿入部６，７は略同一外径となり、一および他の柱体２，３を一体の型枠内で同時に成形することも可能になる。 Further, since the inner diameters of one end side (one inserted portion 12) and the other end side (other inserted portion 13) are substantially the same with respect to the seat plate portion 11 of the joint pipe main body portion 10, one and others One of the pillars 2 and 3 and the other insertion portions 6 and 7 have substantially the same outer diameter, and the one and the other pillars 2 and 3 can be molded at the same time in an integral mold.

また、継手管４と一および他の柱体２，３の一および他の挿入部６，７との間に一および他の抜止部22，23を介在させているため、継手管４と一および他の柱体２，３とが密着し、がたつきが発生しない。 Further, since one and other retaining portions 22 and 23 are interposed between the joint pipe 4 and one and one of the other pillars 2 and 3 and the other insertion portions 6 and 7, the joint pipe 4 and one And other pillars 2 and 3 are in close contact with each other, and rattling does not occur.

そして、組立式コンクリート柱１は、下柱である一の柱体２を建て込み、一のスペーサＳ1を一の柱体２の上端部の一の挿入部６に取り付け、継手管４を上方から取り付け、他のスペーサＳ2を下端部の他の挿入部７に取り付けた上柱である他の柱体３を継手管４に上方から建て込むことで、下から上へと順序良く積み上げるように設置できるので、施工が容易である。 Then, in the assembly type concrete pillar 1, one pillar body 2 which is a lower pillar is built, one spacer S1 is attached to one insertion portion 6 at the upper end portion of one pillar body 2, and the joint pipe 4 is attached from above. By installing and building the other pillar body 3, which is the upper pillar with the other spacer S2 attached to the other insertion portion 7 at the lower end, into the joint pipe 4 from above, it is installed so that it is stacked in order from bottom to top. Since it can be done, construction is easy.

しかも、一および他のスペーサＳ1，Ｓ2は、予め別途形成しておくことができるので、組立式コンクリート柱１を設置する現場での作業が少ないとともに、高精度に形成できる。 Moreover, since one and the other spacers S1 and S2 can be formed separately in advance, less work is required at the site where the assembly-type concrete column 1 is installed, and the spacers S1 and S2 can be formed with high accuracy.

なお、第１の実施の形態において、一および他の抜止部22，23は、樹脂モルタル、あるいは接着剤などの流体状の固定液を固化させて形成してもよい。 In the first embodiment, the one and the other retaining portions 22 and 23 may be formed by solidifying a fluid fixing liquid such as a resin mortar or an adhesive.

すなわち、図４（ａ）ないし図４（ｅ）に示す第２の実施の形態では、まず、図４（ａ）に示すように、予め成形された一の柱体２を設置部Ｇに設置し、図４（ｂ）に示すように、一の柱体２の一の挿入部６に固定液Ｍを塗布し、この固定液Ｍを塗布した一の柱体２の一の挿入部６を、図４（ｃ）に示すように、別途予め形成された継手管４の継手管本体部10の一の被挿入部12に嵌挿し、固定液Ｍ（図４（ｂ））を固化させて一の抜止部22とする。次いで、図４（ｄ）に示すように、予め成形された他の柱体３の他の挿入部７に固定液Ｍを塗布し、この固定液Ｍが塗布された他の柱体３の他の挿入部７を、図４（ｅ）に示すように、継手管４の継手管本体部10の他の被挿入部13に上方から嵌挿し、固定液Ｍ（図４（ｄ））を固化させて他の抜止部23とする。なお、固定液Ｍが固化するまで仮固定手段を用いて継手管４と一および他の柱体２，３とを固定しておき、施工速度を速めることも可能である。このように、継手管４は、継手管本体部10の内径が座板部11に対して一端側と他端側とでそれぞれ略一定となっているので、継手管本体部10をストレート管で構成し、座板部11を平板で構成でき、継手管４を安価に製造できるとともに、一の柱体２の一の挿入部６と他の柱体３の他の挿入部７とに特別な加工を必要とせず、一般的なコンクリート柱の生産工程で容易に製造した一の柱体２および他の柱体３を使用できるなど、上記の第１の実施の形態と同様の作用効果を奏することができ、かつ、組立式コンクリート柱１は、下柱である一の柱体２を建て込み、固定液Ｍを一のスペーサＳ1の上端部の一の挿入部６に塗布し、継手管４を上方から取り付け、固定液Ｍを下端部の他の挿入部７に塗布した上柱である他の柱体３を継手管４に上方から建て込むことで、下から上へと順序良く積み上げるように設置できるので、施工が容易である。 That is, in the second embodiment shown in FIGS. 4 (a) to 4 (e), first, as shown in FIG. 4 (a), one preformed pillar 2 is installed in the installation portion G. Then, as shown in FIG. 4B, the fixing liquid M is applied to the insertion portion 6 of the one pillar body 2, and the one insertion portion 6 of the one pillar body 2 coated with the fixing liquid M is applied. , As shown in FIG. 4 (c), the fixing liquid M (FIG. 4 (b)) is solidified by being inserted into the inserted portion 12 of one of the joint pipe main body 10 of the joint pipe 4 separately formed in advance. Let it be one retaining part 22. Next, as shown in FIG. 4D, the fixing liquid M is applied to the other insertion portion 7 of the other preformed pillar 3, and the other pillar 3 to which the fixing liquid M is applied is applied. As shown in FIG. 4 (e), the insertion portion 7 of the above is inserted into the other inserted portion 13 of the joint pipe main body 10 of the joint pipe 4 from above to solidify the fixing liquid M (FIG. 4 (d)). Let it be the other retaining part 23. It is also possible to fix the joint pipe 4 and one and the other pillars 2 and 3 by using temporary fixing means until the fixing liquid M is solidified to increase the construction speed. As described above, in the joint pipe 4, the inner diameter of the joint pipe main body 10 is substantially constant on one end side and the other end side with respect to the seat plate portion 11, so that the joint pipe main body 10 is a straight pipe. The seat plate portion 11 can be formed of a flat plate, the joint pipe 4 can be manufactured at low cost, and the joint pipe 4 is special to one insertion portion 6 of one pillar 2 and another insertion portion 7 of another pillar 3. It has the same effect as that of the first embodiment described above, for example, one pillar 2 and another pillar 3 easily manufactured in a general concrete pillar production process can be used without requiring processing. Assembled concrete pillars 1 can be constructed by building one pillar body 2 which is a lower pillar, and applying a fixing liquid M to one insertion portion 6 at the upper end of one spacer S1 to form a joint pipe 4 Is attached from above, and the other pillar 3 which is the upper pillar in which the fixing liquid M is applied to the other insertion portion 7 at the lower end is built into the joint pipe 4 from above so that the fixing liquid M is stacked in order from the bottom to the top. Since it can be installed in, construction is easy.

しかも、固定液Ｍそのものを固化させて継手管４と一および他の柱体２，３とを固定しつつ一および他の抜止部22，23を形成するので、一および他の抜止部22，23を形成するための部材と、継手管４と一および他の柱体２，３とを固定する部材とを別個にする場合と比較して、工数や材料数が少なくて済み、組立式コンクリート柱１をより安価に組み立てできるとともに、固定液Ｍを一および他の柱体２，３（一および他の挿入部６，７）と継手管４との隙間を埋めることができる程度に塗布すれば、一および他の抜止部22，23を形成するための部材を予め寸法精度よく形成しておく必要がない。 Moreover, since the fixing liquid M itself is solidified to form the one and the other retaining portions 22 and 23 while fixing the joint pipe 4 and the one and the other pillars 2 and 3, the one and the other retaining portions 22, Compared with the case where the member for forming 23 and the member for fixing the joint pipe 4 and one and the other pillars 2 and 3 are separated, the number of steps and the number of materials are reduced, and the assembly type concrete. The pillar 1 can be assembled at a lower cost, and the fixing liquid M is applied to the extent that the gap between one and other pillars 2 and 3 (one and other insertion portions 6 and 7) and the joint pipe 4 can be filled. For example, it is not necessary to form the members for forming one and the other retaining portions 22 and 23 in advance with high dimensional accuracy.

なお、一の柱体２の一の挿入部６に塗布した固定液と、他の柱体３の他の挿入部７に塗布した固定液とは、同一のものでも異なるものでもよい。また、固定液は、一および他の柱体２，３を継手管本体部10に対して抜け止めできれば、一および他の柱体２，３の一および他の挿入部６，７と継手管本体部10との隙間全体を埋めるように充填されるものに限られない。 The fixative applied to one insertion portion 6 of one prism 2 and the fixative applied to the other insertion portion 7 of the other prism 3 may be the same or different. Further, if the fixing liquid can prevent one and the other pillars 2 and 3 from coming off from the joint pipe main body 10, the one and the other pillars 2 and 3 and the other insertion portions 6 and 7 and the joint pipe It is not limited to the one that is filled so as to fill the entire gap with the main body 10.

また、一および他の柱体２，３の一および他の挿入部６，７に固定液を塗布してから継手管本体部10に挿入する代わりに、一および他の柱体２，３の一および他の挿入部６，７の少なくともいずれかを継手管本体部10に挿入した後、一および他の柱体２，３の一および他の挿入部６，７の少なくともいずれかと継手管本体部10との間の隙間に固定液を注入して固化させることで一および他の抜止部22，23を形成するようにしてもよい。 Further, instead of applying the fixing liquid to one of the one and the other pillars 2 and 3 and the other insertion portions 6 and 7 and then inserting the fixing liquid into the joint pipe main body 10, the one and the other pillars 2 and 3 After inserting at least one of one and the other insertion portions 6 and 7 into the joint pipe main body 10, one and the other pillars 2 and 3 and at least one of the other insertion portions 6 and 7 and the joint pipe main body One and other retaining portions 22 and 23 may be formed by injecting a fixing liquid into the gap between the portions 10 and solidifying the fixing liquid.

次に、第３の実施の形態について図５を参照して説明する。なお、上記の各実施の形態と同様の構成および作用については、同一符号を付し、その説明を省略する。 Next, the third embodiment will be described with reference to FIG. The same components and operations as in each of the above embodiments are designated by the same reference numerals, and the description thereof will be omitted.

本実施の形態は、継手管４の継手管本体部10が、一の柱体２の一の挿入部６が挿入される一端側と、他の柱体３の他の挿入部７が挿入される他端側とで、内径および外径が異なるものである。 In the present embodiment, the joint pipe main body 10 of the joint pipe 4 is inserted into one end side into which one insertion portion 6 of one pillar 2 is inserted and another insertion portion 7 of the other pillar 3. The inner and outer diameters are different from those on the other end side.

継手管４は、一の被挿入部12と他の被挿入部13とが、内径および外径が異なる管により形成され、これらが同軸に接続されて構成されている。本実施の形態において、一の柱体２の一の挿入部６が挿入される一端側である一の被挿入部12の内径および外径が、他の柱体３の他の挿入部７が挿入される他端側である他の被挿入部13の内径および外径よりも大きく設定されている。そのため、継手管４は、一端側と他端側との接続部が段差状に形成されている。一の被挿入部12と他の被挿入部13とは、それぞれ内径および外径が略一定となっている。 The joint pipe 4 is configured such that one inserted portion 12 and the other inserted portion 13 are formed of pipes having different inner and outer diameters, and these are coaxially connected.

It is set larger than the inner and outer diameters of the other inserted portion 13 on the other end side to be inserted. Therefore, in the joint pipe 4, the connecting portion between one end side and the other end side is formed in a stepped shape. The inner diameter and the outer diameter of one inserted portion 12 and the other inserted portion 13 are substantially constant, respectively.

また、座板部11は、継手管本体部10の一端側と他端側との中間部分、つまり一の被挿入部12と他の被挿入部13との境界部分に位置する。座板部11は、継手管本体部10の一端側と他端側とのうち、内径または外径が大きい方、本実施の形態では一端側の内径または外径と等しい直径を有する円板状に形成されている。 Further, the seat plate portion 11 is located at an intermediate portion between one end side and the other end side of the joint pipe main body portion 10, that is, at a boundary portion between one inserted portion 12 and another inserted portion 13. The seat plate portion 11 has a disc shape having a diameter equal to the inner diameter or outer diameter of the one end side and the other end side of the joint pipe main body 10, whichever has the larger inner diameter or outer diameter, and in the present embodiment, the inner diameter or outer diameter of the one end side. Is formed in.

そして、本実施の形態でも、上記の各実施の形態と同様に、設置部に設置した一の柱体２の上端部の一の挿入部６に一のスペーサまたは固定液を配し、一の柱体２の一の挿入部６を継手管４の継手管本体部10の一の被挿入部12に嵌挿して一の抜止部22を形成し、他の柱体３の下端部の他の挿入部７に他のスペーサまたは固定液を配し、他の柱体３の他の挿入部７を継手管４の継手管本体部10の他の被挿入部13に上方から嵌挿し、他の抜止部23を形成することで、組立式コンクリート柱１を組み立てる。 Then, also in the present embodiment, as in each of the above-described embodiments, one spacer or a fixing liquid is arranged in one insertion portion 6 at the upper end portion of one pillar body 2 installed in the installation portion, and one One insertion portion 6 of the pillar body 2 is fitted into one insertion portion 12 of the joint pipe main body portion 10 of the joint pipe 4 to form one retaining portion 22, and the other lower end portion of the other pillar body 3 is formed. Another spacer or fixing liquid is arranged in the insertion portion 7, and the other insertion portion 7 of the other column body 3 is inserted into the other insertion portion 13 of the joint pipe main body portion 10 of the joint pipe 4 from above, and the other By forming the retaining portion 23, the assembling type concrete pillar 1 is assembled.

このように、継手管４は、継手管本体部10の内径が座板部11に対して一端側と他端側とでそれぞれ略一定となっているので、継手管本体部10をストレート管で構成し、座板部11を平板で構成でき、継手管４を安価に製造できるとともに、一の柱体２の一の挿入部６と他の柱体３の他の挿入部７とに特別な加工を必要とせず、一般的なコンクリート柱の生産工程で容易に製造した一の柱体２および他の柱体３を使用できるなど、上記の各実施の形態と同様の作用効果を奏することができる。 As described above, in the joint pipe 4, the inner diameter of the joint pipe main body 10 is substantially constant on one end side and the other end side with respect to the seat plate portion 11, so that the joint pipe main body 10 is a straight pipe. The seat plate portion 11 can be formed of a flat plate, the joint pipe 4 can be manufactured at low cost, and the one insertion portion 6 of one pillar 2 and the other insertion portion 7 of the other pillar 3 are special. It is possible to obtain the same effects as those of the above-described embodiments, such as the fact that one pillar 2 and another pillar 3 easily manufactured in a general concrete pillar production process can be used without the need for processing. can.

また、継手管本体部10の座板部11に対して一端側（一の被挿入部12）と他端側（他の被挿入部13）との内径が異なっているため、一の柱体２と他の柱体３とで、それぞれの目的や用途に応じて、少なくとも一および他の挿入部６，７の外径が互いに異なるものを用いることができる。例えば、本実施の形態では、設置部に設置される一の柱体２として外径が大きいものを用いることができるので、より強度が高い組立式コンクリート柱１とすることができる。 Further, since the inner diameters of one end side (one inserted portion 12) and the other end side (the other inserted portion 13) of the seat plate portion 11 of the joint pipe main body portion 10 are different, one pillar body. It is possible to use at least one and the other insertion portions 6 and 7 having different outer diameters depending on the purpose and application of the 2 and the other pillar 3. For example, in the present embodiment, since one pillar body 2 having a large outer diameter can be used as one pillar body 2 installed in the installation portion, it is possible to obtain an assembly-type concrete pillar 1 having higher strength.
