Description

本発明は、例えば、建築構造物における基礎梁コンクリート中に埋め込まれた鉄骨柱の下端部が、基礎梁コンクリート中の主鉄筋と、仲介連結部材を介して連結される、鉄骨柱と梁コンクリート主鉄筋の連結構造に関するものである。   The present invention provides, for example, a steel column and a beam concrete main body in which a lower end portion of a steel column embedded in a foundation beam concrete in a building structure is coupled to a main reinforcing bar in the foundation beam concrete via an intermediate coupling member. The present invention relates to a reinforcing bar connection structure.

従来技術として、特許文献１に開示されているように、基礎梁コンクリート中に埋め込まれた鉄骨柱の下端部が、基礎梁コンクリート中の主鉄筋と仲介連結部材を介して連結される、鉄骨柱と基礎梁コンクリートの主鉄筋の連結構造があった。この従来の鉄骨柱と主鉄筋の連結構造は、例えば、板状であってその平面形状の中央に開口部を有する仲介連結部材が、その開口部に嵌合する鉄骨柱の下端部に溶接により一体的に固定され、この仲介連結部材の外周側面（鉛直面）に開口するメネジ孔に、主鉄筋の端部のオネジ部がネジ込まれるようになっていた。
特許第４０３３３４０号公報 As disclosed in Patent Document 1, as a conventional technique, a steel column in which a lower end portion of a steel column embedded in the foundation beam concrete is coupled to a main reinforcing bar in the foundation beam concrete via an intermediate coupling member. And there was a connection structure of the main rebar of foundation beam concrete. This conventional steel column and main reinforcing bar connection structure is, for example, a plate-like intermediate connecting member having an opening in the center of its planar shape, welded to the lower end of the steel column that fits into the opening. The male screw portion at the end of the main reinforcing bar is screwed into the female screw hole that is fixed integrally and opens on the outer peripheral side surface (vertical surface) of the intermediate connecting member.
Japanese Patent No. 4033340

しかしながら、上記従来の鉄骨柱と基礎梁コンクリート主鉄筋の連結構造においては、その仲介連結部材の中央の開口部に鉄骨柱が嵌合するようになっていることにより、この仲介連結部材が、鉄骨柱の側面から水平方向に大きく張り出して大型化する構造となっているので、それだけ仲介連結部材に使う材料が増えて、コストや重量が増加してしまうという問題があった。   However, in the connection structure of the conventional steel column and the foundation beam concrete main reinforcing bar, the intermediate connection member is fitted into the central opening of the intermediate connection member. Since the structure has a structure in which the column is greatly extended from the side surface of the pillar to increase the size, there is a problem that the material used for the intermediate connecting member increases and the cost and weight increase accordingly.

そこで本発明は、上記問題点に鑑みて、仲介連結部材を小型化することができると共に、主鉄筋と仲介連結部材を連結するために用いるオネジ状部材やメネジ状部材を仲介連結部材に取り付ける作業を容易にすることができる、鉄骨柱と梁コンクリート主鉄筋の連結構造を提供することを課題とするものである。   Therefore, in view of the above problems, the present invention can reduce the size of the mediation connecting member, and also attach the male screw-like member and the female screw-like member used to connect the main reinforcing bar and the mediation connection member to the mediation connection member. It is an object of the present invention to provide a connection structure of a steel column and a beam concrete main reinforcing bar that can facilitate the above.

Two through-holes 22 and two through-holes 22 that pass through the peripheral walls 4b and 4d and whose axes are horizontally parallel to each other at a predetermined interval are formed to be staggered in the height direction. .

次に、仲介連結部材８のそれぞれは、１枚の板状の本体部材１４と、２本の棒部材１６と、８個のネジ棒部材２３とを備えている。図１及び図２中において鉄骨柱４の右側方向に伸びるように配筋される主鉄筋１２と、後述するカプラー２５（メネジ状部材）を介して連結する仲介連結部材８は、その本体部材１４が、鉄骨柱４における周壁４ｂに対向するように配置されている。   Next, each of the mediation connecting members 8 includes one plate-like main body member 14, two rod members 16, and eight screw rod members 23. In FIG. 1 and FIG. 2, the main reinforcing bar 12 that is arranged to extend in the right direction of the steel column 4 and the intermediate connecting member 8 that is connected via a coupler 25 (female-like member) described later is a main body member 14.

Is arranged so as to protrude outward from the outer peripheral surface of the peripheral wall 4d of the steel column 4, and a nut 18 (corresponding to a retaining means) is screwed to the male screw portion 16a. The nut 18 is caught on the outer peripheral surface of the peripheral wall 4 d of the steel column 4.

また、図２中において鉄骨柱４の上側方向に伸びるように配筋される主鉄筋１２と連結する仲介連結部材８は、その本体部材１４が、鉄骨柱４における周壁４ｃに対向するように配置されている。   In addition, the intermediate connecting member 8 connected to the main reinforcing bar 12 arranged to extend upward in the steel column 4 in FIG. 2 is disposed so that the main body member 14 faces the peripheral wall 4 c of the steel column 4. Has been.

また、この図２中上側方向に伸びる主鉄筋１２と連結する仲介連結部材８の、２本の棒部材１６のそれぞれは、鉄骨柱４における周壁４ａ，４ｃを貫通する２つの貫通孔２２のそれぞれに、その周壁４ｃ側の開口部から挿し込まれ、先端部のオネジ部１６ａが鉄骨柱４の周壁４ａの外周面から外側に突出するように配置されると共に、このオネジ部１６ａに、ナット１８がネジ締結されている。ナット１８は、鉄骨柱４の周壁４ａの外周面に引っ掛かるようになっている。   In addition, each of the two rod members 16 of the intermediate connection member 8 connected to the main reinforcing bar 12 extending in the upward direction in FIG. 2 includes two through holes 22 penetrating the peripheral walls 4a and 4c in the steel column 4 respectively. The male screw portion 16a at the tip end portion is inserted so as to protrude outward from the outer peripheral surface of the peripheral wall 4a of the steel column 4, and the nut 18 is inserted into the male screw portion 16a. Is screwed. The nut 18 is caught on the outer peripheral surface of the peripheral wall 4 a of the steel column 4.

仲介連結部材８のそれぞれには、図１及び図２に示すように、その本体部材１４における鉄骨柱４とは反対側の面には、機械加工によりオネジ（オネジ状部）が外周部に形成されたネジ棒部材２３（オネジ状部材）の基端側（図３中左端側）が、水平方向に４本ずつ、そして高さ方向に２本ずつ、合計８本ずつ設けられている。   As shown in FIGS. 1 and 2, each of the intermediate connection members 8 is formed with male threads (male-like portions) on the outer surface of the main body member 14 on the side opposite to the steel column 4 by machining. The base end side (left end side in FIG. 3) of the screw rod member 23 (a male screw-like member) thus provided is provided in a total of eight, four in the horizontal direction and two in the height direction.

このネジ棒部材２３の端面は、ネジ棒部材２３と仲介連結部材８の本体部材１４との間に発生するアークにより、ネジ棒部材２３が仲介連結部材８の本体部材１４に接合されるような、いわゆるスタッド溶接により仲介連結部材８の本体部材１４に接合されるようになっている。   The end surface of the screw rod member 23 is joined to the main body member 14 of the mediation connecting member 8 by an arc generated between the screw rod member 23 and the main body member 14 of the mediation connecting member 8. The main body member 14 of the intermediate connecting member 8 is joined by so-called stud welding.

図３に示すように、仲介連結部材８のそれぞれの本体部材１４に設けられたネジ棒部材２３の先端側（図中右端側）は、カプラー２５（メネジ状部材）を介して、主鉄筋１２の端部と連結するようになっている。すなわち、同図に示すように、主鉄筋１２の端部には機械加工によりオネジが形成されたオネジ状端部１２ａが形成されており、仲介連結部材８のネジ棒部材２３は、カプラー２５を介して、主鉄筋１２のオネジ状端部１２ａと連結するようになっている。   As shown in FIG. 3, the front end side (right end side in the figure) of the screw rod member 23 provided on each main body member 14 of the mediation connecting member 8 is connected to the main reinforcing bar 12 via a coupler 25 (female thread-like member). It connects with the end of the. That is, as shown in the figure, the end portion of the main reinforcing bar 12 is formed with a male screw-like end portion 12a formed with a male thread by machining, and the screw rod member 23 of the intermediate connecting member 8 is connected to the coupler 25. It connects with the external thread-like edge part 12a of the main rebar 12.

仲介連結部材８のネジ棒部材２３と、主鉄筋１２のオネジ状端部１２ａは、互いに逆ネジ状の関係となっている。また、このことと関連して、カプラー２５の一方の半分の長さ部分の内側に形成されたメネジと、その他方の半分の長さ部分の内側に形成されたメネジとの間も、互いに逆ネジ状の関係となっている。したがって、長くて重い主鉄筋１２を手で持って回転させなくとも、カプラー２５を回転させるだけで容易にネジ棒部材２３と主鉄筋１２を連結することができる。このとき、ネジ棒部材２３と主鉄筋１２は互いが近付くように引っ張られるような力を受けて、たるむことなくしっかりと緊張して連結することができる。   The threaded rod member 23 of the mediation connecting member 8 and the male threaded end 12a of the main reinforcing bar 12 are in a reverse threaded relationship. Further, in connection with this, the internal thread formed inside one half of the coupler 25 and the internal thread formed inside the other half are also opposite to each other. It has a screw-like relationship. Therefore, the screw rod member 23 and the main rebar 12 can be easily connected by simply rotating the coupler 25 without rotating the long and heavy main rebar 12 by hand. At this time, the threaded rod member 23 and the main rebar 12 can be connected to each other without being slackened by receiving a force of being pulled so as to approach each other.

このような第１の実施の形態に係る鉄骨柱と基礎梁コンクリート主鉄筋の連結構造２によれば、仲介連結部材８のそれぞれは、連結する主鉄筋１２側にのみ本体部材１４が配置されるようになっていると共に、仲介連結部材８にネジ棒部材２３を接合するようにしたため、仲介連結部材８が、従来のように、鉄骨柱の側面の全周囲から水平方向に大きく張り出す必要がなくなるので、仲介連結部材８を小型化することができる。   According to the connection structure 2 between the steel column and the foundation beam concrete main reinforcing bar according to the first embodiment, each of the intermediate connecting members 8 has the main body member 14 arranged only on the main reinforcing bar 12 side to be connected. In addition, since the screw rod member 23 is joined to the intermediate connecting member 8, it is necessary that the intermediate connecting member 8 protrudes horizontally in the horizontal direction from the entire periphery of the side surface of the steel column as in the prior art. Since it disappears, the mediation connection member 8 can be reduced in size.

また、仲介連結部材８の本体部材１４へのネジ棒部材２３の接合は、スタッド溶接により本体部材１４における鉄骨柱４とは反対側の面にネジ棒部材２３の端面が接合されるようになっているので、仲介連結部材８へのネジ棒部材２３の取り付け作業を容易にすることができる。   Further, the screw rod member 23 is joined to the main body member 14 of the mediation connecting member 8 by joining the end surface of the screw rod member 23 to the surface of the main body member 14 opposite to the steel column 4 by stud welding. Therefore, the attachment work of the screw rod member 23 to the mediation connecting member 8 can be facilitated.

また、ネジ棒部材２３の先端側（図３中右端側）は、カプラー２５（メネジ状部材）を介して、主鉄筋１２のオネジ状端部１２ａと連結するようになっているため、長くて重い主鉄筋１２を手で持って回転させなくとも、カプラー２５を回転させるだけで容易にネジ棒部材２３と主鉄筋１２を連結することができるので、仲介連結部材８への主鉄筋１２の連結作業を容易にすることができる。   Further, the distal end side (the right end side in FIG. 3) of the screw rod member 23 is connected to the male threaded end portion 12a of the main reinforcing bar 12 via the coupler 25 (female threaded member). Since the screw rod member 23 and the main rebar 12 can be easily connected by simply rotating the coupler 25 without rotating the heavy main rebar 12 by hand, the main rebar 12 can be connected to the intermediate connecting member 8. Work can be facilitated.

また、本実施の形態に係る鉄骨柱と基礎梁コンクリート主鉄筋の連結構造２によれば、前記特許文献１と比べて、以下のような作用効果を奏するようになる。すなわち、前記特許文献１には、カプラーを仲介連結部材の上面に溶接により接合する実施例が記載されているが、このような場合には、カプラーの側面に沿って溶接する必要があるため、隣接するカプラー同士が障害となって溶接しにくくなるため、ある程度の間隔が必要となり、接合できるカプラーの個数が限定され、結局、これに連結できる主鉄筋の本数も限定されてしまうという問題が生じる。   Moreover, according to the connection structure 2 of the steel column and the foundation beam concrete main reinforcement which concerns on this Embodiment, compared with the said patent document 1, there exist the following effects. That is, Patent Document 1 describes an example in which a coupler is joined to the upper surface of the intermediate coupling member by welding, but in such a case, it is necessary to weld along the side surface of the coupler. Adjacent couplers become obstacles and are difficult to weld, so a certain amount of spacing is required, the number of couplers that can be joined is limited, and eventually the number of main reinforcing bars that can be connected to this is also limited. .

これに対して、本実施の形態に係る鉄骨柱と基礎梁コンクリート主鉄筋の連結構造２によれば、仲介連結部材８の本体部材１４の側面に、スタッド溶接等によりネジ棒部材２３の端部を接合するようになっているため、前記特許文献１よりも狭い間隔でネジ棒部材２３を接合できるので、接合できるオネジ状部材の個数を増加させ、これに連結できる主鉄筋１２の本数を増加することができる。   On the other hand, according to the connection structure 2 of the steel column and the basic beam concrete main reinforcing bar according to the present embodiment, the end portion of the screw rod member 23 is formed on the side surface of the body member 14 of the intermediate connection member 8 by stud welding or the like. Since the screw rod member 23 can be joined at a narrower interval than the above-mentioned Patent Document 1, the number of male screw-like members that can be joined is increased, and the number of main reinforcing bars 12 that can be connected to this is increased. can do.

図４から図６は、本発明の第２の実施の形態に係る鉄骨柱と基礎梁コンクリート主鉄筋の連結構造２０について説明するために参照する図である。
前記第１の実施の形態に係る基礎梁コンクリート主鉄筋の連結構造２と同様の部分には同じ符号を用いて説明し、同様の構成についての重複する説明はできるだけ省略するものとする。 FIGS. 4 to 6 are views referred to for explaining a connecting structure 20 of the steel column and the basic beam concrete main reinforcing bar according to the second embodiment of the present invention.
The same parts as those of the connecting structure 2 of the foundation beam concrete main reinforcing bars according to the first embodiment will be described using the same reference numerals, and overlapping descriptions of similar configurations will be omitted as much as possible.

本実施の形態に係る鉄骨柱と基礎梁コンクリート主鉄筋の連結構造２０は、前記第１の実施の形態における仲介連結部材８の代わりに、仲介連結部材２１を備えている。前記第１の実施の形態における仲介連結部材８のそれぞれは、その本体部材１４における鉄骨柱４とは反対側の面にネジ棒部材２３（オネジ状部材）が設けられていたが、本実施の形態で用いる仲介連結部材２１のそれぞれは、図４及び図５に示すように、その本体部材１４における鉄骨柱４とは反対側の面に、カプラー１０（メネジ状部材）が接合されている。   The connection structure 20 of the steel column and the foundation beam concrete main reinforcement according to the present embodiment includes an intermediate connection member 21 instead of the intermediate connection member 8 in the first embodiment. Each of the intermediate connecting members 8 in the first embodiment is provided with the screw rod member 23 (male-like member) on the surface of the main body member 14 on the side opposite to the steel column 4. As shown in FIGS. 4 and 5, each of the intermediate connection members 21 used in the form has a coupler 10 (female screw-like member) joined to a surface of the main body member 14 opposite to the steel column 4.

すなわち、仲介連結部材２１のそれぞれには、その本体部材１４における鉄骨柱４とは反対側の面に、カプラー１０が、水平方向に４個ずつ、高さ方向に２個ずつの、合計８個ずつ設けられている。   In other words, each of the intermediate connecting members 21 has a total of eight couplers 10 on the surface of the main body member 14 opposite to the steel pillars 4, each having four couplers 10 in the horizontal direction and two in the height direction. It is provided one by one.

そして、カプラー１０はその端面が、いわゆる圧接加工手段を用いて仲介連結部材２１の本体部材１４に接合されるようになっている。圧接加工手段とは、カプラー１０を軸周りに高速回転させて、本体部材１４の鉄骨柱４とは反対側の面に押し付けることにより発生する摩擦熱により、互いに接触する部分を溶融、圧着させて接合する加工手段をいう。   The end face of the coupler 10 is joined to the main body member 14 of the mediation connecting member 21 by using so-called pressure welding processing means. The pressure welding means means that the parts that come into contact with each other are melted and pressure-bonded by frictional heat generated by rotating the coupler 10 around the axis at a high speed and pressing it against the surface of the body member 14 opposite to the steel column 4. The processing means to join.

カプラー１０のそれぞれには、図６に示すように、主鉄筋１２のオネジ状端部１２ａが連結している。すなわち、カプラー１０の軸孔部はその内周面に機械加工によりメネジが形成されたメネジ孔となっており（メネジ状孔）、このメネジ孔に上記オネジ状端部１２ａがネジ込まれることにより、カプラー１０のそれぞれに主鉄筋１２が連結している。   As shown in FIG. 6, each of the couplers 10 is connected to a male threaded end 12 a of the main reinforcing bar 12. That is, the shaft hole portion of the coupler 10 is a female screw hole having a female screw formed on the inner peripheral surface thereof by machining (female screw hole), and the male screw end portion 12a is screwed into the female screw hole. The main rebar 12 is connected to each of the couplers 10.

このような第２の実施の形態に係る、鉄骨柱と基礎梁コンクリート主鉄筋の連結構造２０によれば、仲介連結部材２１のそれぞれは、連結する主鉄筋１２側にのみ本体部材１４が配置されるようになっていると共に、この本体部材１４にカプラー１０を接合するようにしたため、仲介連結部材２１が、従来のように、鉄骨柱の側面の全周囲から水平方向に大きく張り出す必要がなくなるので、仲介連結部材２１を小型化することができる。   According to the connecting structure 20 of the steel column and the foundation beam concrete main reinforcing bar according to the second embodiment, the intermediate connecting member 21 has the main body member 14 disposed only on the connecting main reinforcing bar 12 side. In addition, since the coupler 10 is joined to the main body member 14, it is not necessary for the intermediary connecting member 21 to protrude greatly from the entire periphery of the side surface of the steel column in the horizontal direction as in the prior art. Therefore, the mediation connecting member 21 can be reduced in size.

また、仲介連結部材２１の本体部材１４へのカプラー１０の接合は、圧接加工手段を用いて本体部材１４における鉄骨柱４とは反対側の面にカプラー１０の端面が接合されるようになっているので、仲介連結部材２１へのカプラー１０の取り付け作業を容易にすることができる。   In addition, the coupler 10 is joined to the body member 14 of the mediation connecting member 21 by joining the end face of the coupler 10 to the surface of the body member 14 opposite to the steel column 4 by using a press-working means. Therefore, the attachment work of the coupler 10 to the mediation connecting member 21 can be facilitated.

また、本実施の形態に係る鉄骨柱と基礎梁コンクリート主鉄筋の連結構造２０によれば、前記特許文献１の仲介連結部材において、その上面に溶接で接合されるカプラーの個数がある程度の個数までに限定されていたことと比べると、仲介連結部材２１の本体部材１４の側面に、圧接接合手段等によりカプラー１０の端部を接合するようになっているため、前記特許文献１よりも狭い間隔でカプラー１０を接合できるので、接合できるカプラー１０の個数を増加させ、これに連結できる主鉄筋１２の本数を増加することができる。   Further, according to the connection structure 20 of the steel column and the basic beam concrete main reinforcing bar according to the present embodiment, in the intermediate connection member of Patent Document 1, the number of couplers joined to the upper surface by welding is limited to a certain number. Compared to that described above, the end of the coupler 10 is joined to the side surface of the body member 14 of the mediation connecting member 21 by a pressure welding means or the like, so that the gap is narrower than that of Patent Document 1. Thus, the number of couplers 10 that can be joined can be increased, and the number of main reinforcing bars 12 that can be connected to the coupler 10 can be increased.

図７から図９は、本発明の第３の実施の形態に係る鉄骨柱と基礎梁コンクリート主鉄筋の連結構造７０について説明するために参照する図である。
前記第２の実施の形態に係る基礎梁コンクリート主鉄筋の連結構造２０と同様の部分には同じ符号を用いて説明し、同様の構成についての重複する説明はできるだけ省略するものとする。 FIGS. 7 to 9 are views referred to for explaining a connection structure 70 of a steel column and a foundation beam concrete main reinforcing bar according to a third embodiment of the present invention.
The same parts as those of the connecting structure 20 of the foundation beam concrete main reinforcing bars according to the second embodiment will be described using the same reference numerals, and overlapping descriptions of similar configurations will be omitted as much as possible.

本実施の形態に係る基礎梁コンクリート主鉄筋の連結構造７０は、前記第２の実施の形態における仲介連結部材２１の代わりに、図７及び図８に示すように、仲介連結部材７１を備えている。この仲介連結部材７１は、その本体部材１４がカプラー１０を介さないで主鉄筋１２のオネジ状端部１２ａと直接連結する点において、前記第２の実施の形態における仲介連結部材２１と異なっている。   The foundation beam concrete main reinforcing bar connection structure 70 according to the present embodiment includes an intermediate connection member 71 as shown in FIGS. 7 and 8 instead of the intermediate connection member 21 in the second embodiment. Yes. The intermediate connecting member 71 is different from the intermediate connecting member 21 in the second embodiment in that the main body member 14 is directly connected to the male threaded end portion 12a of the main reinforcing bar 12 without the coupler 10 interposed therebetween. .

すなわち、前記第２の実施の形態における仲介連結部材２１のそれぞれは、その本体部材１４における鉄骨柱４とは反対側の面にカプラー１０が接合されていたのに対して、本実施の形態で用いる仲介連結部材７１は、図９に示すように、その本体部材１４における水平方向の肉厚内に、軸が水平方向のメネジ孔１４ａ（メネジ状孔）が設けられている。そして、この仲介連結部材７１のメネジ孔１４ａに、主鉄筋１２のオネジ状端部１２ａが直接ネジ込まれて連結されている。   That is, in each of the intermediate connection members 21 in the second embodiment, the coupler 10 is joined to the surface of the main body member 14 opposite to the steel column 4, whereas in the present embodiment, As shown in FIG. 9, the intermediate coupling member 71 to be used is provided with a female screw hole 14 a (a female screw-like hole) whose horizontal axis is in the horizontal thickness of the main body member 14. The male threaded end 12a of the main reinforcing bar 12 is directly screwed into and connected to the female threaded hole 14a of the intermediate coupling member 71.

なお、この実施の形態においては、メネジ孔１４ａが、仲介連結部材７１の本体部材１４の肉厚を貫通している場合について説明したが、このように貫通しないで、メネジ孔１４ａが本体部材１４の肉厚の途中で行き止まりになるように形成してもよい。   In this embodiment, the case where the female screw hole 14a has penetrated the thickness of the main body member 14 of the mediation connecting member 71 has been described. However, the female screw hole 14a is not penetrated in this way and the main body member 14 is not penetrated. You may form so that it may become a dead end in the middle of the thickness of.

このような第３の実施の形態に係る鉄骨柱と基礎梁コンクリート主鉄筋の連結構造７０によっても、前記第２の実施の形態において仲介連結部材２１を小型化できたのと同様に、仲介連結部材７１を小型化することができる。また、前記第２の実施の形態における仲介連結部材２１のカプラー１０が不要となるので、部品数を減らすことができる。   The connection structure 70 of the steel column and the foundation beam concrete main reinforcing bar according to the third embodiment as described above is similar to the connection connection member 21 in the second embodiment, in which the connection connection member 21 can be downsized. The member 71 can be reduced in size. Further, since the coupler 10 of the intermediate connecting member 21 in the second embodiment is not necessary, the number of parts can be reduced.

また、本実施の形態に係る鉄骨柱と基礎梁コンクリート主鉄筋の連結構造７０によれば、前記特許文献１の仲介連結部材において、その上面に溶接で接合されるカプラーの個数がある程度の個数までに限定されていたことと比べると、仲介連結部材７１の本体部材１４に複数のメネジ孔１４ａを形成するようになっているため、これら複数のメネジ孔１４ａ同士の間隔を狭くすることができるので、これら複数のメネジ孔１４ａに連結できる主鉄筋１２の本数を増加することができる。   Moreover, according to the connection structure 70 of the steel column and the foundation beam concrete main reinforcement according to the present embodiment, in the intermediate connection member of Patent Document 1, the number of couplers joined to the upper surface by welding is limited to a certain number. Since the plurality of female screw holes 14a are formed in the main body member 14 of the intermediate connecting member 71, the interval between the plurality of female screw holes 14a can be reduced. The number of main reinforcing bars 12 that can be connected to the plurality of female screw holes 14a can be increased.

The same parts as those of the connecting structure 20 of the foundation beam concrete main reinforcing bars according to the second embodiment will be described using the same reference numerals, and overlapping descriptions of similar configurations will be omitted as much as possible.

前記第２の実施の形態においては、図６に示すように、カプラー１０の軸孔部に形成されたメネジ孔に、ネジ棒部材３２及びカプラー２５を介さないで主鉄筋１２のオネジ状端部１２ａを直接ネジ込むようになっていたが、図１０に示すように、仲介連結部材２１の本体部材１４に設けられたカプラー１０の上記メネジ孔に、主鉄筋１２より遥かに短いネジ棒部材３２（オネジ状部材）の一方の約半分の長さ部分のオネジをネジ込み、このネジ棒部材３２の他方の約半分の長さ部分のオネジを、上記カプラー１０より長い、前記第１の実施の形態で用いたものと同じカプラー２５の、一方の約半分の長さ部分のメネジ孔にネジ結合させ、そのカプラー２５の他方の約半分の長さ部分の、逆方向のメネジ孔に、主鉄筋１２のオネジ状端部１２ａをネジ結合させるようになっている。   In the second embodiment, as shown in FIG. 6, the male threaded end portion of the main reinforcing bar 12 is not inserted into the female screw hole formed in the shaft hole portion of the coupler 10 via the screw rod member 32 and the coupler 25. Although the screw 12a is screwed directly, as shown in FIG. 10, a screw rod member 32 that is much shorter than the main reinforcing bar 12 is inserted into the female screw hole of the coupler 10 provided in the main body member 14 of the intermediate connecting member 21. The male screw of about half length of one of the (male-like member) is screwed, and the male screw of the other half length of the screw rod member 32 is longer than the coupler 10 in the first embodiment. The same coupler 25 used in the form is screwed into the female screw hole of one half of the length, and the main reinforcing bar is inserted into the female screw hole in the opposite direction of the other half of the coupler 25. 12 male threaded ends 12a And it is adapted to screw connection.

The intermediate connecting member 21 and the main reinforcing bar 12 can be easily connected by simply rotating the coupler 25 without rotating the hand 12 by hand.

The same parts as those in the connection structure 70 of the foundation beam concrete main reinforcing bar according to the third embodiment will be described using the same reference numerals, and overlapping descriptions of the same configurations will be omitted as much as possible.

前記第３の実施の形態においては、図９に示すように、仲介連結部材７１のメネジ孔１４ａに主鉄筋１２のオネジ状端部１２ａを直接ネジ込むようになっていたが、この第５の実施の形態においては、図１１に示すように、仲介連結部材７１のメネジ孔１４ａに、ネジ棒部材３２の一方の端部をネジ込み、このネジ棒部材３２の他方の端部の側の約半分の長さ部分のオネジを、カプラー２５の一方の約半分の長さ部分のメネジにネジ結合させ、そのカプラー２５の他方の約半分の長さ部分の、逆方向のメネジに、主鉄筋１２のオネジ状端部１２ａをネジ結合させるようになっている。   In the third embodiment, as shown in FIG. 9, the male threaded end portion 12a of the main reinforcing bar 12 is directly screwed into the female screw hole 14a of the mediation connecting member 71. In the embodiment, as shown in FIG. 11, one end portion of the screw rod member 32 is screwed into the female screw hole 14 a of the mediation connecting member 71, and the other end portion side of the screw rod member 32 is reduced.
