Description

本発明は、柱梁の接合方法及び柱梁の接合構造に関する。 The present invention relates to a beam-column joining method and a beam-column joining structure.

特許文献１には、鉄筋コンクリート柱と鉄骨梁との仕口部に関する技術が開示されている。この先行技術では、左右の鉄骨梁のエンドプレートを固定螺子棒で連結してエンドプレートを型枠の一部として利用している。 Patent Document 1 discloses a technique relating to a joint portion between a reinforced concrete column and a steel frame beam. In this prior art, the end plates of the left and right steel beams are connected by fixed screw rods, and the end plates are used as part of the formwork.

特許文献２には、柱を鉄筋コンクリート造、梁を鉄骨造とする混合構造骨組に関する技術が開示されている。この先行技術では、鉄骨造大梁を柱フェース面まで伸ばし、且つ鉄骨造大梁の端部には柱フェース面に接する支圧板を設けている。そして、鉄筋コンクリート造柱の外側のみに鉄骨造大梁が密着配置されている構成とし、支圧板にスタッドボルトが設けられている。 Patent Document 2 discloses a technique relating to a mixed structure frame in which columns are made of reinforced concrete and beams are made of steel. In this prior art, the steel-framed girder is extended to the column face surface, and a bearing plate in contact with the column face surface is provided at the end of the steel-framed girder. The steel-framed girders are closely arranged only on the outside of the reinforced concrete columns, and the bearing plates are provided with stud bolts.

ここで、鉄筋コンクリート製の柱に鉄骨梁を接合する場合は、柱の仕口部に鉄骨梁を接合する。 Here, when joining a steel beam to a column made of reinforced concrete, the steel beam is joined to the joint of the column.

しかし、この方法では、鉄筋コンクリート製の柱の仕口部と鉄骨梁との施工誤差を吸収するために、仕口部と鉄骨梁との間に無収縮モルタルを充填したり、仕口部に予めブラケットを接合して鉄骨梁を接合したりするなど、施工工数が多くなる。 However, in this method, in order to absorb the construction error between the joint of the reinforced concrete column and the steel beam, a non-shrink mortar is filled between the joint and the steel beam, or the joint is preliminarily filled with non-shrink mortar. The number of construction steps increases, such as joining brackets and joining steel beams.

本発明は、上記事実を鑑み、鉄筋コンクリート製の柱と鉄骨梁とを、施工工数を抑えつつ、柱の仕口部と鉄骨梁の施工誤差を吸収して接合することが目的である。 In view of the above facts, it is an object of the present invention to join a column made of reinforced concrete and a steel beam while suppressing construction man-hours and absorbing a construction error between the column joint and the steel beam.

第一態様は、鉄筋コンクリート製の柱を構築する工程と、鉄骨梁の端部に接合され、突出部を有するプレートの下側に延在する延在部を前記柱の上部の柱側面に固定する工程と、前記柱の上部に、前記突出部が埋設するようにコンクリートを打設して、仕口部を構築する工程と、を備える柱梁の接合方法である。 The first aspect is a step of constructing a column made of reinforced concrete, and fixing an extending portion joined to the end of the steel beam and extending to the lower side of the plate having a protruding portion to the column side surface of the upper part of the column. It is a method of joining columns and beams including a step and a step of placing concrete on the upper part of the column so that the projecting portion is embedded to construct a joint portion.

第一態様の柱梁の接合方法では、鉄骨梁の端部に接合したプレートの延在部を鉄筋コンクリート製の柱の上部の柱側面に固定して仕口部のコンクリートを打設するので、仕口部を構築した後に鉄骨梁を接合する施工方法と比較し、施工工数を抑えつつ、鉄骨梁と仕口部との施工誤差を吸収することができる。 In the method of joining columns and beams of the first aspect, the extending portion of the plate joined to the end of the steel frame beam is fixed to the side surface of the column above the column made of reinforced concrete, and the concrete of the joint is placed. Compared with the construction method of joining the steel beam after constructing the mouth, it is possible to absorb the construction error between the steel beam and the joint while reducing the construction manpower.

第二態様は、前記仕口部を構築する工程では、前記柱の上部と前記鉄骨梁の上部とにコンクリートを打設し、前記仕口部とスラブとを一体的に構築する、請求項１に記載の柱梁の接合方法である。 In the second aspect , in the step of constructing the joint portion, concrete is cast on the upper part of the column and the upper part of the steel beam, and the joint portion and the slab are integrally constructed. It is a method of joining columns and beams described in 1.

第二態様の柱梁の接合方法では、仕口部とスラブとを一体的に構築するので、施工工数が削減する。 In the method of joining columns and beams in the second aspect , the joint portion and the slab are integrally constructed, so that the construction man-hours are reduced.

第三態様は、鉄骨梁の端部に接合され、鉄筋コンクリート製の柱における仕口部に埋設される突出部を有し、前記仕口部に接合されたプレートと、前記プレートに形成され、前記仕口部よりも下側に延在し、前記仕口部の下の柱側面に固定された延在部と、を備える柱梁の接合構造である。 The third aspect has a protruding portion that is joined to the end of a steel beam and is embedded in a joint in a column made of reinforced concrete, and a plate joined to the joint and a plate formed in the plate and described above. It is a joint structure of columns and beams including an extending portion extending below the joint portion and fixed to the side surface of the column below the joint portion.

第三態様の柱梁の接合方法では、鉄骨梁の端部に接合したプレートの延在部を鉄筋コンクリート製の柱側面に固定して、仕口部のコンクリートを打設することができるので、施工工数を抑えつつ、鉄骨梁と仕口部との施工誤差を吸収することができる。 In the method of joining columns and beams of the third aspect, the extending portion of the plate joined to the end of the steel frame beam can be fixed to the side surface of the column made of reinforced concrete, and concrete at the joint can be placed. It is possible to absorb the construction error between the steel beam and the joint while reducing the number of steps.

本発明によれば、鉄筋コンクリート製の柱と鉄骨梁とを、施工工数を抑えつつ、柱の仕口部と鉄骨梁の施工誤差を吸収して接合することができる。 According to the present invention, a column made of reinforced concrete and a steel beam can be joined by absorbing a construction error between the joint of the column and the steel beam while suppressing the construction man-hours.

図１〜図３に示すように、鉄骨梁５０の一方の端部５０Ａには、プレート６０が接合されている。鉄骨梁５０の一方の端部５０Ａとプレート６０との接合は、どのような接合方法であってもよいが、本実施形態では、溶接又はボルトによって接合されている。 As shown in FIGS. 1 to 3, a plate 60 is joined to one end 50A of the steel beam 50. One end 50A of the steel beam 50 and the plate 60 may be joined by any joining method, but in the present embodiment, they are joined by welding or bolts.

プレート６０の板面には、先端部に頭部６３を有する頭付スタッド６２が設けられている。突出部の一例としての頭付スタッド６２は、鉄筋コンクリート製の仕口部３０に埋設されている。 A headed stud 62 having a head 63 at the tip thereof is provided on the plate surface of the plate 60. The headed stud 62 as an example of the protruding portion is embedded in the joint portion 30 made of reinforced concrete.

図１及び図２に示すように、プレート６０は、仕口部３０よりも下側に延在する延在部６４が形成されている。この延在部６４は、仕口部３０の下の下側柱２２の上部２３の柱側面２３Ａに固定されている。なお、固定方法はどのようなものであってもよいが、本実施形態では、下側柱２２の上部２３に埋め込まれたインサートにボルト６８で固定されている。 As shown in FIGS. 1 and 2, the plate 60 is formed with an extending portion 64 extending below the joint portion 30.

［施工方法］
つぎに、本実施形態の柱梁架構１０の施工方法の一例について説明する。 [Construction method]
Next, an example of the construction method of the column-beam frame 10 of the present embodiment will be described.

図１（Ａ）に示すように、プレキャスト鉄筋コンクリート製の下側柱２２を設置する。鉄骨梁５０の一端側の端部５０Ａに接合されたプレート６０の下側に延在する延在部６４を下側柱２２の上部２３の柱側面２３Ａに固定する。 As shown in FIG. 1 (A), the lower column 22 made of precast reinforced concrete is installed. The extending portion 64 extending below the plate 60 joined to the end portion 50A on one end side of the steel frame beam 50 is fixed to the column side surface 23A of the upper portion 23 of the lower column 22.

図１（Ｂ）に示すように、頭付スタッド６２が埋設するように下側柱２２の上部２３にコンクリートを打設して、仕口部３０を構築する。このとき、プレート６０を型枠の一部として利用する。また、鉄骨梁５０の上にコンクリートを打設してスラブ４２を構築する。つまり、仕口部３０とスラブ４２とを一体的に構築する。 As shown in FIG. 1 (B), concrete is poured into the upper portion 23 of the lower pillar 22 so that the headed stud 62 is embedded to construct the joint portion 30. At this time, the plate 60 is used as a part of the mold. Further, concrete is cast on the steel beam 50 to construct the slab 42. That is, the joint portion 30 and the slab 42 are integrally constructed.

プレート６０の延在部６４の下側柱２２の上部２３への固定は仮設である。よって、施工後、固定を外してもよい。 Fixing of the lower pillar 22 of the extending portion 64 of the plate 60 to the upper portion 23 is temporary. Therefore, the fixing may be removed after construction.

なお、プレキャスト鉄筋コンクリート製の梁１４、１６、１８及び上側柱２４の仕口部３０への接合は、どのような方法であってもよいが、以下に一例を説明する。 Any method may be used for joining the precast reinforced concrete beams 14, 16, 18 and the upper column 24 to the joint portion 30, and an example will be described below.

仕口部３０から突き出す梁主筋を仕口部３０に配筋し、仕口部３０を打設後、この梁主筋にプレキャスト鉄筋コンクリート製の梁１４、１６、１８に埋め込んだ機械式継手に挿入して接合している。或いは、梁１４、１６、１８から突き出した柱主筋を仕口部３０内で機械式継手によって接合してもよい。 The beam main bar protruding from the joint portion 30 is arranged in the joint portion 30, and after the joint portion 30 is placed, the beam main bar is inserted into the mechanical joint embedded in the precast reinforced concrete beams 14, 16 and 18. Are joined. Alternatively, the column main bars protruding from the beams 14, 16 and 18 may be joined in the joint portion 30 by a mechanical joint.

また、プレキャスト鉄筋コンクリート製の下側柱２２から柱主筋を仕口部３０よりも長く突き出し、仕口部３０を打設後、この突き出た柱主筋にプレキャスト鉄筋コンクリート製の上側柱２４に埋め込んだ機械式継手に挿入して接合している。 Further, a column main bar is projected from the lower column 22 made of precast reinforced concrete longer than the joint portion 30, and after the joint portion 30 is placed, the main column is embedded in the upper column 24 made of precast reinforced concrete. It is inserted into the joint and joined.

［作用及び効果］
つぎに、本実施形態の作用及び効果について説明する。 [Action and effect]
Next, the operation and effect of this embodiment will be described.

鉄骨梁５０の端部５０Ａに接合したプレート６０には、延在部６４が形成されているので、仕口部３０を打設する前の下側柱２２の上部２３の柱側面２３Ａに固定することができる。 Since the extending portion 64 is formed in the plate 60 joined to the end portion 50A of the steel frame beam 50, the joint portion 30 is fixed to the column side surface 23A of the upper portion 23 of the lower column 22 before being placed. be able to.

そして、鉄骨梁５０の端部５０Ａに接合したプレート６０の延在部６４を下側柱２２の上部２３の柱側面２３Ａに固定して仕口部３０のコンクリートを打設することで、仕口部３０とプレート６０との間に無収縮モルタルを充填する等し、鉄骨梁５０と仕口部３０との施工誤差を吸収する必要がなくなる。したがって、施工工数を抑えつつ、鉄骨梁５０と仕口部３０との施工誤差を吸収することができる。 Then, the extending portion 64 of the plate 60 joined to the end portion 50A of the steel frame beam 50 is fixed to the column side surface 23A of the upper portion 23 of the lower column 22, and the concrete of the joint portion 30 is cast to form the joint. It is not necessary to absorb the construction error between the steel frame beam 50 and the joint portion 30 by filling a non-shrink mortar between the portion 30 and the plate 60. Therefore, it is possible to absorb the construction error between the steel frame beam 50 and the joint portion 30 while suppressing the construction man-hours.

また、本実施形態では、現場打ちの仕口部３０とスラブ４２とを一体的に構築することができるので、施工工数を削減することができる。 Further, in the present embodiment, since the in-situ casting joint portion 30 and the slab 42 can be integrally constructed, the construction man-hours can be reduced.

ここで、本発明が適用されない場合は、現場打ちの仕口部３０を打設したのち、一旦コンクリート作業を中断して鉄骨梁５０を接合し、再び現場打ちのスラブ４２の打設を行うことになるので、現場でのコンクリートの打設作業が分断される。 Here, when the present invention is not applied, after placing the cast-in-place joint portion 30, the concrete work is temporarily interrupted, the steel beam 50 is joined, and the cast-in-place slab 42 is placed again. Therefore, the concrete placing work at the site is divided.

しかし、本実施形態では、前述のように現場打ちの仕口部３０とスラブ４２とを一体的に構築することで、コンクリートの打設作業が集約され、作業効率を高めることができる。 However, in the present embodiment, by integrally constructing the in-situ casting joint portion 30 and the slab 42 as described above, the concrete placing work is integrated and the work efficiency can be improved.

また、本実施形態では、頭付スタッド６２が仕口部３０に定着することで、鉄骨梁５０の端部５０Ａが仕口部３０に接合される。よって、例えば、ボルトナットによる接合と比較し、作業工数が削減される。 Further, in the present embodiment, the end portion 50A of the steel frame beam 50 is joined to the joint portion 30 by fixing the headed stud 62 to the joint portion 30. Therefore, as compared with joining with bolts and nuts, for example, the work man-hours are reduced.

また、頭付スタッド６２は、定着筋と比較して、プレート６０からの突出寸法（定着代）が短くても所望の接合強度を得ることができる。よって、仕口部３０に埋設される各種鉄筋と干渉しにくいので、施工しやすい。 Further, the headed stud 62 can obtain a desired joint strength even if the protruding dimension (fixing allowance) from the plate 60 is shorter than that of the fixing bar. Therefore, it is easy to construct because it does not easily interfere with various reinforcing bars embedded in the joint portion 30.

また、仕口部３０を打設する際のコンクリートの型枠の一部としてプレート６０を利用することで、施工コストが低減する。なお、本実施形態では、プレート６０のＹ方向の両端部には、仕口部３０の仕口部側面３０Ｂ、３０Ｃに沿うように張り出した張出部６６Ａ、６６Ｄが形成されているので、型枠として利用しやすい。 Further, by using the plate 60 as a part of the concrete formwork when placing the joint portion 30, the construction cost is reduced. In the present embodiment, overhanging portions 66A and 66D are formed on both ends of the plate 60 in the Y direction so as to extend along the side surfaces 30B and 30C of the joint portion 30. Easy to use as a frame.

＜その他＞
尚、本発明は上記実施形態に限定されない。 <Others>
The present invention is not limited to the above embodiment.

例えば、上記実施形態では、プレート６０には、張出部６６Ａ、６６Ｂが形成されていいたが、張出部６６Ａ、６６Ｄが形成されていなくてもよい。 For example, in the above embodiment, the overhanging portions 66A and 66B are formed on the plate 60, but the overhanging portions 66A and 66D may not be formed.

また、例えば、上記実施形態では、仕口部３０とスラブ４２とを一体的に構築したが、仕口部３０とスラブ４２とを別々に構築してもよい。 Further, for example, in the above embodiment, the joint portion 30 and the slab 42 are integrally constructed, but the joint portion 30 and the slab 42 may be constructed separately.

また、例えば、上記実施形態では、プレート６０は、仕口部３０の仕口部側面３０Ａと仕口部側面３０Ｂ、３０Ｄの一部を覆っている。しかし、プレート６０が仕口部３０の全部の仕口部側面３０Ａ、３０Ｂ、３０Ｃ、３０Ｄを覆う構造とすれば、仕口部３０がプレート６０によって覆われるため、仕口部３０の内部のフープ筋を省略或いは削減することができる。 Further, for example, in the above embodiment, the plate 60 covers a part of the joint portion side surface 30A and the joint portion side surfaces 30B and 30D of the joint portion 30. However, if the plate 60 has a structure that covers all the side surfaces 30A, 30B, 30C, and 30D of the joint portion 30, the joint portion 30 is covered by the plate 60, so that the hoop inside the joint portion 30 is covered. The streaks can be omitted or reduced.

プレート６０が仕口部３０の全部の仕口部側面３０Ａ、３０Ｂ、３０Ｃ、３０Ｄを覆う構造とは、例えば、柱２０に接合される梁の全てが、本発明が適用された鉄骨梁５０である場合などである。 The structure in which the plate 60 covers all the joint side surfaces 30A, 30B, 30C, and 30D of the joint 30 is, for example, all the beams joined to the column 20 are the steel beam 50 to which the present invention is applied. For example, in some cases.

また、上記実施形態では、柱２０、梁１４、１６、１８は、いずれもプレキャスト鉄筋コンクリート製であったが、これに限定されない。これらを現場で打設して構築する構造であってもよい。この場合、例えば、下側柱２２と上側柱２４の柱主筋は、仕口部３０内で機械式継手によって継がれてもよい。 Further, in the above embodiment, the columns 20, the beams 14, 16 and 18 are all made of precast reinforced concrete, but the present invention is not limited thereto. It may be a structure in which these are cast and constructed on site. In this case, for example, the column main bars of the lower column 22 and the upper column 24 may be joined by a mechanical joint in the joint portion 30.

また、上記実施形態では、頭付スタッド６２が仕口部３０に定着することで、鉄骨梁５０の端部５０Ａが仕口部３０に接合されているが、これに限定されない。頭付スタッド６２以外の突出部、例えば定着筋やインサート金具をプレート６０に設けてもよい。 Further, in the above embodiment, the end portion 50A of the steel frame beam 50 is joined to the joint portion 30 by fixing the headed stud 62 to the joint portion 30, but the present invention is not limited to this. A protrusion other than the headed stud 62, for example, a fixing bar or an insert fitting may be provided on the plate 60.

更に、本発明の要旨を逸脱しない範囲において種々なる態様で実施し得ることは言うまでもない Furthermore, it goes without saying that it can be carried out in various embodiments without departing from the gist of the present invention.
