Description

本発明は、プレキャストコンクリート（ＰＣ）柱梁の接合構造、この接合構造を含んだ柱梁架構構造、およびＰＣ柱梁の接合方法に関する。 The present invention, the bonding structure of the precast concrete (PC) Column, Column Frame structure including the bonding structure, and relates to the bonding how the PC Column.

従来よりコンクリート柱梁の接合構造として、図１８に示す構成が一般的である。同図に示す従来の柱梁の接合構造では、ＰＣ梁２００の端部から梁主筋２０２（同図の例では下端筋）を突出させる。そして、同じ直線上で隣り合う２本のＰＣ梁２００を、それらの端部が柱コンクリート２０４上で相対向するように設置し、床コンクリートと共に柱梁仕口部にコンクリートを打設することにより各端部から突出する梁主筋２０２を連結する。なお、図１８では、下端筋のみをＰＣ梁２００の端部から突出させ、上端筋はＰＣ梁２００から露出させた構成を示しているが、上下両方の梁端筋をＰＣ梁２００に埋入して端面から突出させる場合もある。また、図１８では下端筋を折り曲げることで現場打設コンクリートとの定着を確保するようにしているが、これに限らず、梁主筋同士を機械式継手で連結してもよい。   Conventionally, the structure shown in FIG. 18 is common as a joint structure of concrete column beams. In the conventional column beam joint structure shown in the figure, the beam main bar 202 (the bottom bar in the example of the figure) is projected from the end of the PC beam 200. Then, two PC beams 200 adjacent on the same straight line are installed so that their end portions are opposed to each other on the column concrete 204, and concrete is placed in the column beam joint with the floor concrete. The beam main bars 202 protruding from each end are connected. FIG. 18 shows a configuration in which only the lower end bar protrudes from the end of the PC beam 200 and the upper end bar is exposed from the PC beam 200. However, both the upper and lower beam end bars are embedded in the PC beam 200. In some cases, it may protrude from the end face. Further, in FIG. 18, the lower end reinforcement is bent to secure the fixing with the on-site placing concrete. However, the present invention is not limited to this, and the beam main reinforcement may be connected by a mechanical joint.

また、特許文献１には、柱梁の接合部をＰＣ部材で構成した構造が開示されている。この特許文献１に開示される構造では、図１９に示すようなＰＣ部材３００を介して柱梁を接合する。このＰＣ部材３００は、直方体状の本体３０２と、この本体３０２を鉛直方向および水平方向に貫通する複数の貫通孔３０４ａ，３０４ｂとから構成される。かかるＰＣ部材３００の水平方向の貫通孔３０４ｂに梁筋を挿通させてグラウトを注入することで、ＰＣ部材３００に梁筋を一体化させる。このＰＣ部材３００を柱梁仕口部まで揚重し、柱頭部から突出した柱筋を鉛直方向の貫通孔３０４ａに挿通させてグラウトを注入することで柱梁を接合する。
特開平２−１０１２３７号公報 Patent Document 1 discloses a structure in which a column beam joint is formed of a PC member. In the structure disclosed in Patent Document 1, column beams are joined via a PC member 300 as shown in FIG. The PC member 300 includes a rectangular parallelepiped main body 302 and a plurality of through holes 304a and 304b that penetrate the main body 302 in the vertical direction and the horizontal direction. By inserting a beam streak through the horizontal through hole 304b of the PC member 300 and injecting grout, the beam member is integrated with the PC member 300. The PC member 300 is lifted up to the column beam joint, the column beam protruding from the column head is inserted into the vertical through hole 304a, and the grout is injected to join the column beam.
Japanese Patent Laid-Open No. 2-101237

上記のように、図１８に示す従来の構成では、現場にて柱梁仕口部にコンクリートを打設することが必要である。また、特許文献１に開示される構成においても、梁のコンクリートは現場で打設することになる。しかし、現場でコンクリートを打設すると、型枠の設置・解体作業が必要となるなど工程数が増大し、コスト増や工期の長期化を招いてしまう。
このため、現場でのコンクリート打設の施工箇所を削減可能な柱梁接合構造も開発されており、これについては本願出願人が既に特許出願済みである（特願２００３―７５１２５号）。 As described above, in the conventional configuration shown in FIG. 18, it is necessary to place concrete in the column beam joint at the site. Also in the configuration disclosed in Patent Document 1, the concrete of the beam is placed on site. However, when concrete is placed on site, the number of processes increases due to the necessity of installation and dismantling work of the formwork, leading to an increase in cost and a longer construction period.
For this reason, a beam-column joint structure that can reduce the number of construction sites for concrete placement on site has been developed, and a patent application has already been filed by the applicant of this application (Japanese Patent Application No. 2003-75125).

ここで、図１及び図２を参照しながら、この特許出願済みの柱梁接合構造１０について説明する。図１は、この接合構造１０を示す斜視図であり、図２は、図１の接合構造１０の鉛直断面図である。なお、説明の便宜上、これらの図に示すように、互いに直交する３方向をそれぞれ、上下方向、左右方向、および前後方向と定義する。   Here, with reference to FIG. 1 and FIG. 2, the patent-filed column-beam joint structure 10 will be described. FIG. 1 is a perspective view showing the joining structure 10, and FIG. 2 is a vertical sectional view of the joining structure 10 in FIG. 1. For convenience of explanation, as shown in these drawings, three directions orthogonal to each other are defined as an up-down direction, a left-right direction, and a front-rear direction, respectively.

図示のように、この柱梁接合構造１０は、ＰＣ梁１とＰＣ柱４とを、ＰＣ柱４上に配置される仕口パネル３を介して接合するものである。なお、図１および図２では、ＰＣ梁１、ＰＣ柱４、仕口パネル３、および中継筋４ａが分解された状態を示しており、各部材を図中矢印で示す向きに移動し設置することで柱梁接合構造１０が完成する。   As shown in the figure, the column beam joining structure 10 is for joining the PC beam 1 and the PC column 4 via the joint panel 3 arranged on the PC column 4. 1 and 2 show a state in which the PC beam 1, the PC pillar 4, the joint panel 3, and the relay bar 4a are disassembled, and the respective members are moved and installed in the directions indicated by the arrows in the drawings. This completes the column-beam joint structure 10.

ＰＣ梁１は柱梁架構のスパン長に亘る長さを有しており、その両端部が、仕口パネル３を介してＰＣ柱４に接合される。ただし、柱梁架構のスパン長が長い場合には、ＰＣ梁を複数（例えば２〜３個）に分割し、それらを接合してＰＣ梁１として用いてもよい。仕口パネル３は、直方体状に構成されたＰＣ部材であり、鉛直方向に貫通する複数の柱主筋孔３ａと、水平方向に貫通する複数の梁主筋孔３ｂとを含んでいる。   The PC beam 1 has a length that spans the span length of the column beam frame, and both ends thereof are joined to the PC column 4 via the joint panel 3. However, when the span length of the column beam frame is long, the PC beam may be divided into a plurality (for example, two to three) and joined to be used as the PC beam 1. The joint panel 3 is a PC member configured in a rectangular parallelepiped shape, and includes a plurality of column main reinforcement holes 3a penetrating in the vertical direction and a plurality of beam main reinforcement holes 3b penetrating in the horizontal direction.

ＰＣ梁１の梁主筋１ａは、梁コンクリートに埋入されてその端部が梁端面から突出している。そして、仕口パネル３の両側に配置されるＰＣ梁１の梁主筋１ａが、仕口パネル３の梁主筋孔３ｂに両側から挿入され、梁主筋孔３ｂ内に埋入された継手によって相互に連結される。なお、梁主筋孔３ｂ内の継手の構造については後述する。   The main beam 1a of the PC beam 1 is embedded in the beam concrete, and its end protrudes from the beam end surface. The beam main bars 1a of the PC beam 1 arranged on both sides of the joint panel 3 are inserted into the beam main bar holes 3b of the joint panel 3 from both sides, and are mutually connected by joints embedded in the beam main bar holes 3b. Connected. The structure of the joint in the beam main hole 3b will be described later.

仕口パネル３の柱主筋孔３ａには上方から中継筋４ａが挿入される。中継筋４ａは、下階のＰＣ柱４の柱主筋４ｂと、上階のＰＣ柱４の柱主筋４ｂとを中継するための鉄筋である。ＰＣ柱４の上端部には柱主筋連結用継手４ｃが埋入されており、中継筋４ａの下端がこの柱主筋連結用継手４ｃに定着されることにより下階の柱主筋４ｂに連結される。また、ＰＣ柱４の下端部にも柱主筋連結用継手４ｃが埋入されており、この柱主筋連結用継手４ｃに中継筋４ａの上端が定着される。すなわち、図１および図２において、不図示の上階のＰＣ柱４を施工する場合には、その下端部の柱主筋連結用継手４ｃに中継筋４ａの上端が定着されることになる。このように、当該柱梁接合構造１０では、ＰＣ柱４の上下端部に夫々柱主筋連結用継手４ｃ、４ｃを埋入し、下階のＰＣ柱４の上端側の柱主筋連結用継手４ｃと、上階のＰＣ柱４の下端側の柱主筋連結用継手４ｃとの間に、仕口パネル３を貫通する中継筋４ａを連結する構成としている。   A relay bar 4a is inserted into the main column hole 3a of the joint panel 3 from above. The relay bar 4a is a reinforcing bar for relaying the column main bar 4b of the PC column 4 on the lower floor and the column main bar 4b of the PC column 4 on the upper floor. A column main bar coupling joint 4c is embedded in the upper end portion of the PC pillar 4, and the lower end of the relay bar 4a is fixed to the column main bar coupling joint 4c so as to be coupled to the lower column main bar 4b. . A column main bar coupling joint 4c is also embedded in the lower end portion of the PC column 4, and the upper end of the relay bar 4a is fixed to the column main bar coupling joint 4c. That is, in FIG. 1 and FIG. 2, when constructing an unillustrated upper-level PC column 4, the upper end of the relay bar 4 a is fixed to the column main bar coupling 4 c at the lower end. As described above, in the column beam connection structure 10, the column main bar coupling joints 4 c and 4 c are respectively embedded in the upper and lower ends of the PC column 4, and the column main bar coupling joint 4 c on the upper end side of the PC column 4 on the lower floor. And the relay reinforcement 4a which penetrates the joint panel 3 is connected between the column main reinforcement connection joint 4c on the lower end side of the PC pillar 4 on the upper floor.

これらのＰＣ部材１、３、４を用いて柱梁接合構造１０を施工する場合には、図１に示すように、先ず柱梁架構の左端部に位置するＰＣ柱４−１上に仕口パネル３−１を設置し、その柱主筋孔３ａへ上方から中継筋４ａを挿入する。次に、前記仕口パネル３−１の右側方にＰＣ梁１−１を配置し、この位置から、当該ＰＣ梁１−１を左方向に水平移動させることによって、前記仕口パネル３−１の梁主筋孔３ｂに、前記ＰＣ梁１−１の左端部から突出する梁主筋１ａを挿入する。そうしたら、前記ＰＣ柱４−１の右隣のＰＣ柱４−２上に設置すべき次の仕口パネル３−２を、前記ＰＣ梁１−１の右側方に配置し、この位置から、この仕口パネル３−２を左方向に水平移動させることによって、その梁主筋孔３ｂに、前記ＰＣ梁１−１の右端部から突出する梁主筋１ａを挿入させつつ当該仕口パネル３−２を前記ＰＣ柱４−２上に設置する。そして、この仕口パネル３−２に対しても、その柱主筋孔３ａに上方から中継筋４ａを挿入して下階のＰＣ柱４−２に連結すると共に、当該仕口パネル３−２の右側方に配置されたＰＣ梁１−１を左方向に水平移動させることによって、その左端部から突出する梁主筋１ａを前記仕口パネル３−２の梁主筋孔３ｂへ挿入しつつ設置する。そして、このような作業を繰り返して柱梁を接合していくことにより柱梁架構を構築する。   When constructing the beam-column joint structure 10 using these PC members 1, 3, 4, as shown in FIG. 1, first, a joint is formed on the PC column 4-1 positioned at the left end of the column beam frame. The panel 3-1 is installed, and the relay bar 4a is inserted into the column main muscle hole 3a from above. Next, the PC beam 1-1 is arranged on the right side of the joint panel 3-1, and the PC panel 1-1 is horizontally moved from this position to the left, whereby the joint panel 3-1. The beam main reinforcing bar 1a protruding from the left end portion of the PC beam 1-1 is inserted into the beam main reinforcing bar hole 3b. Then, the next joint panel 3-2 to be installed on the PC column 4-2 on the right side of the PC column 4-1 is arranged on the right side of the PC beam 1-1, and from this position, By horizontally moving the joint panel 3-2 in the left direction, the joint main panel 3-2 is inserted into the beam principal reinforcement hole 3b while inserting the principal beam 1a protruding from the right end of the PC beam 1-1. Is installed on the PC pillar 4-2. And also to this joint panel 3-2, while inserting the relay bar | burr 4a into the column main muscle hole 3a from the upper direction and connecting with the PC pillar 4-2 of a lower floor, By horizontally moving the PC beam 1-1 arranged on the right side in the left direction, the beam main reinforcing bar 1a protruding from the left end is inserted into the main beam hole 3b of the joint panel 3-2 and installed. Then, by repeating such operations, the column beam frame is constructed by joining the column beams.

なお、ここでは、左右方向について説明したが、このような作業が、前後方向に対しても行われるのは言うまでもなく、これら左右方向及び前後方向への構築を繰り返して、平面的な柱梁架構を構築するようになっている。   Although the left-right direction has been described here, it is needless to say that such work is also performed in the front-rear direction, and the construction of the planar column beam frame is repeated by repeating the construction in the left-right direction and the front-rear direction. Is supposed to build.

ところで、前記構築中の適宜なタイミングで、前記梁主筋孔３ｂ、柱主筋孔３ａ、及び柱主筋孔用継手４ｃ内には、それぞれにグラウトが注入される。そして、これによって、これら梁主筋孔等３ｂ、３ａ、４ｃに、前記梁主筋１ａ又は中継筋４ａがそれぞれ定着されて、ＰＣ柱４及びＰＣ梁１は前記仕口パネル３を介して一体化される。   By the way, grout is injected into the beam main reinforcement hole 3b, the column main reinforcement hole 3a, and the column main reinforcement hole joint 4c at an appropriate timing during the construction. As a result, the beam main reinforcing bar 1a or the relay reinforcing bar 4a is fixed to the beam main reinforcing bar holes 3b, 3a, 4c, respectively, and the PC pillar 4 and the PC beam 1 are integrated through the joint panel 3. The

図３は、仕口パネル３の梁主筋孔３ｂに梁主筋１ａが定着される様子を説明するための仕口パネル３の鉛直断面図である。同図に示すように、梁主筋孔３ｂには鞘管２が設けられており、梁主筋１ａの先端が梁主筋孔３ｂの両側から鞘管２の内部に達するまで挿入される。仕口パネル３には、その外表面と梁主筋孔３ｂとを連通するグラウト注入孔３ｃが設けられており、このグラウト注入孔３ｃからグラウトが注入されることで、梁主筋１ａが鞘管２に定着される。なお、鞘管２の外周面にはほぼ全長に亘って凹凸部を設けるようにして、鞘管２と仕口パネル３のコンクリートとの付着力を高めるようにしてもよいし、また、図３において、鞘管２が仕口パネル３の全幅に亘る長さを有する構成としてもよい。   FIG. 3 is a vertical sectional view of the joint panel 3 for explaining a state in which the beam main reinforcement 1a is fixed in the beam main reinforcement hole 3b of the connection panel 3. As shown in the figure, a sheath tube 2 is provided in the beam main reinforcement hole 3b, and the distal end of the beam reinforcement 1a is inserted from both sides of the beam reinforcement hole 3b until reaching the inside of the sheath tube 2. The joint panel 3 is provided with a grout injection hole 3c that communicates the outer surface thereof with the beam main reinforcement hole 3b. The grout injection from the grout injection hole 3c allows the beam main reinforcement 1a to be connected to the sheath tube 2. To be established. The outer peripheral surface of the sheath tube 2 may be provided with a concavo-convex portion over almost the entire length so as to increase the adhesion between the sheath tube 2 and the concrete of the joint panel 3, and FIG. The sheath tube 2 may have a length that extends over the entire width of the joint panel 3.

図４は、仕口パネル３の柱主筋孔３ａ及びＰＣ柱４の柱主筋連結用継手４ｃに、中継筋４ａが定着される様子の説明図であって、仕口パネル３及びＰＣ柱４を鉛直断面視で示している。同図に示すように、ＰＣ柱４の上下端部にそれぞれ埋入された柱主筋連結用継手４ｃは、外周に凹凸部を有する短尺の鞘管である。そして、仕口パネル３の柱主筋孔３ａに挿入された中継筋４ａの下端は、下階のＰＣ柱４の前記鞘管４ｃの内部に達するまで挿入される一方、当該中継筋４ａの上端は、上階のＰＣ柱４の前記鞘管４ｃの内部に挿入される。一方、仕口パネル３には、その外表面と柱主筋孔３ａとを連通するグラウト柱入孔３ｄが設けられており、このグラウト柱入孔３ｄからグラウトが注入されることで、柱主筋孔３ａおよび前記鞘管４ｃの内部にグラウトが注入されて、中継筋４ａは柱主筋孔３ａおよび前記鞘管４ｃに定着される。なお、グラウトの注入の仕方としては、ポンプを用いて前記グラウト柱入孔３ｄにグラウトを圧入する等が挙げられるが、これに限るものではない。   FIG. 4 is an explanatory view showing a state in which the relay bar 4a is fixed to the column main bar hole 3a of the joint panel 3 and the column main bar coupling joint 4c of the PC column 4, and the joint panel 3 and the PC column 4 are connected to each other. Shown in vertical section. As shown in the figure, the column main bar coupling joints 4c embedded in the upper and lower ends of the PC column 4 are short sheath pipes having an uneven portion on the outer periphery. The lower end of the relay bar 4a inserted into the column main muscle hole 3a of the joint panel 3 is inserted until reaching the inside of the sheath pipe 4c of the PC column 4 on the lower floor, while the upper end of the relay bar 4a is The upper column PC pillar 4 is inserted into the inside of the sheath tube 4c. On the other hand, the spout panel 3 is provided with a grout column insertion hole 3d that communicates the outer surface thereof with the column main muscle hole 3a, and the grout is injected from the grout column insertion hole 3d, whereby the column main muscle hole is provided. Grout is injected into 3a and the inside of the sheath tube 4c, and the relay muscle 4a is fixed to the columnar muscle hole 3a and the sheath tube 4c. In addition, as a method of injecting grout, for example, a grout may be press-fitted into the grout column insertion hole 3d using a pump, but it is not limited thereto.

そして、以上説明してきた特許出願済みの柱梁接合構造１０によれば、グラウト注入によって柱梁を接合可能であることから、現場でのコンクリート打設の施工箇所を大幅に削減可能である。但し、現場でのコンクリート打設を不必要にできるものではなく、すなわち、柱梁架構を構成する仕口パネル３とＰＣ梁１との接合の幾つかに対しては、従前の現場コンクリート打設で対処せざるを得ない。   And according to the patent-pending column beam joint structure 10 demonstrated above, since a column beam can be joined by grout injection | pouring, the construction location of concrete placement in a field can be reduced significantly. However, on-site concrete placement is not unnecessary, that is, for some of the joints between the joint panel 3 and the PC beam 1 constituting the column beam frame, the conventional on-site concrete placement is performed. I have to deal with it.

この現場コンクリート打設が必要となる様子を、図５の上面視概略図に示す柱梁架構の簡易モデルを用いて説明する。なお、この簡易モデルは、図５（ａ）に示すように前後方向及び左右方向で規定される水平平面内に等ピッチで格子目状に６カ所のＰＣ柱４−１、４−２、…４−６が設けられ、かつ、図５（ｊ）に示すように、これらＰＣ柱４−１、４−２、…４−６の間に、左右方向及び前後方向にＰＣ梁１−１、１−２、…１−７を渡して柱梁架構を構築する例である。   The manner in which this concrete placement is necessary will be described using a simplified model of a column beam frame shown in the schematic top view of FIG. As shown in FIG. 5 (a), this simple model has six PC pillars 4-1, 4-2,... In a grid pattern at an equal pitch in a horizontal plane defined by the front and rear direction and the left and right direction. 4-6, and, as shown in FIG. 5 (j), between these PC pillars 4-1, 4-2,... 1-2,... 1-7 is an example of building a column beam frame.

この柱梁架構を、前述の柱梁接合構造１０を用いて構築する場合には、例えば、始めに、図５（ａ）の左後ろに位置するＰＣ柱４−１上に仕口パネル３−１を配置する。そして、図５（ｂ）〜図５（ｅ）に示すように、この仕口パネル３−１の右方に、ＰＣ梁１−１、仕口パネル３−２、ＰＣ梁１−２、仕口パネル３−３の順番でこれら部材を配置する。なお、ここで、ＰＣ梁１の長手方向は左右方向に揃えている。そして、前記順番で、各部材１−１、３−２、１−２、および３−３を、矢印で示す左方向に水平移動させるが、各水平移動の際に、各梁主筋孔３ｂに対して梁主筋１ａを挿入してＰＣ梁１と仕口パネル３とを接続していき、最終的に図５（ｆ）に示す接続状態にする。なお、この接続状態にあっては、各仕口パネル３は、対応するＰＣ柱４上に位置している。また、以下では説明を省略するが、仕口パネル３には上方から前記中継筋４ａが挿入され下階のＰＣ柱４に連結されているとともに、適宜タイミングで、前記柱主筋孔３ａ、梁主筋孔３ｂ、及び柱主筋連結用継手４ｃ内にグラウトが注入されているのは言うまでもない。   When this column beam frame is constructed using the above-mentioned column beam connection structure 10, for example, first, the joint panel 3- is placed on the PC column 4-1 located at the left rear in FIG. 1 is placed. Then, as shown in FIGS. 5B to 5E, on the right side of the joint panel 3-1, the PC beam 1-1, the joint panel 3-2, the PC beam 1-2, These members are arranged in the order of the mouth panel 3-3. Here, the longitudinal direction of the PC beam 1 is aligned in the left-right direction. And in the said order, each member 1-1, 3-2, 1-2, and 3-3 is horizontally moved in the left direction shown by the arrow, but in each horizontal movement, each beam main reinforcement hole 3b is moved. On the other hand, the main beam 1a is inserted to connect the PC beam 1 and the joint panel 3, and finally the connection state shown in FIG. In this connection state, each joint panel 3 is located on the corresponding PC pillar 4. Although the description will be omitted below, the relay bar 4a is inserted into the joint panel 3 from above and connected to the PC pillar 4 on the lower floor, and at the appropriate timing, the column main bar hole 3a and the beam main bar are connected. Needless to say, grout is injected into the hole 3b and the columnar bar joint 4c.

次に、図５（ｇ）に示すように、各ＰＣ柱４上に設置された３つの仕口パネル３−１、３−２、３−３に対して、その前方に、長手方向を前後方向に揃えてＰＣ梁１−３、１−４、１−５を配置する。そして、各ＰＣ梁１−３、１−４、１−５を後方へ水平移動させ、当該水平移動の際に、各梁主筋孔３ｂに梁主筋１ａを挿入して、仕口パネル３−１、３−２、３−３に各ＰＣ梁１−３、１−４、１−５を接続し、図５（ｈ）に示す接続状態にする。   Next, as shown in FIG. 5 (g), the longitudinal direction is moved forward and backward with respect to the three joint panels 3-1, 3-2, and 3-3 installed on each PC pillar 4. The PC beams 1-3, 1-4, and 1-5 are arranged in the direction. Then, the PC beams 1-3, 1-4, and 1-5 are horizontally moved rearward, and the beam main bars 1a are inserted into the main beam holes 3b at the time of the horizontal movement. The PC beams 1-3, 1-4, and 1-5 are connected to 3-2 and 3-3 so that the connection state shown in FIG.

そうしたら、図５（ｉ）示すように、各ＰＣ梁１−３、１−４、１−５の前方に、仕口パネル３−４、３−５、３−６を配置する。そして、各仕口パネル３−４、３−５、３−６を後方へ水平移動させ、当該水平移動の際に、各梁主筋孔３ｂに梁主筋１ａを挿入して、各ＰＣ梁１−３、１−４、１−５に仕口パネル３−４、３−５、３−６を接続し、図５（ｊ）に示す接続状態にする。なお、この接続状態においては、各仕口パネル３−４、３−５、３−６は、対応するＰＣ柱４−４、４−５、４−６上に位置しているのは言うまでもない。   Then, as shown in FIG. 5 (i), the joint panels 3-4, 3-5 and 3-6 are arranged in front of the PC beams 1-3, 1-4 and 1-5. And each joint panel 3-4, 3-5, 3-6 is horizontally moved backward, and the main beam 1a is inserted into each main beam hole 3b at the time of the horizontal movement, and each PC beam 1- 3, 1-4, and 1-5 are connected to the connection panels 3-4, 3-5, and 3-6, and the connection state shown in FIG. In this connection state, it is needless to say that each of the connection panels 3-4, 3-5, 3-6 is located on the corresponding PC pillars 4-4, 4-5, 4-6. .

そして、最後に、仕口パネル３−４と仕口パネル３−５との間にＰＣ梁１−６を設置するとともに、仕口パネル３−５と仕口パネル３−６との間に、ＰＣ梁１−７を設置すれば、当該柱梁架構は完成する。   And finally, while installing the PC beam 1-6 between the joint panel 3-4 and the joint panel 3-5, between the joint panel 3-5 and the joint panel 3-6, If the PC beam 1-7 is installed, the column beam frame will be completed.

しかし、ここで、仕口パネル３−４と仕口パネル３−５との間に介挿すべきＰＣ梁１−６、並びに、仕口パネル３−５と仕口パネル３−６との間に介設すべきＰＣ梁１−７は、その両端部から梁主筋１ａが突出しているが、当該ＰＣ梁１−６、１−７の水平移動は、左右の何れか一方向に対してしか行えない。このために、ＰＣ梁１−６、１−７は、その左右の両脇にある何れか一方の仕口パネル３の梁主筋孔３ｂに対してしか梁主筋１ａを挿入できず、残るもう一方の仕口パネル３に対しては梁主筋１ａを挿入することができない。   However, here, the PC beam 1-6 to be inserted between the joint panel 3-4 and the joint panel 3-5, and between the joint panel 3-5 and the joint panel 3-6. The main beam 1a of the PC beam 1-7 to be interposed protrudes from both ends of the PC beam 1-7. However, the horizontal movement of the PC beam 1-6, 1-7 can be performed only in one of the left and right directions. Absent. For this reason, in the PC beams 1-6 and 1-7, the beam main bar 1a can be inserted only into the beam main bar hole 3b of either one of the right and left sides of the joint panel 3, and the remaining beam remains. The beam main reinforcing bar 1a cannot be inserted into the joint panel 3.

従って、梁主筋孔３ｂに梁主筋１ａを挿入できない方のＰＣ梁１−６、１−７の端部と、これに対応する仕口パネル３との接合については、従前の現場コンクリート打設に頼らざるを得ず、結果として、当該柱梁接合構造１０では、現場コンクリート打設の施工箇所を無くすことはできない。   Therefore, for the joining of the ends of the PC beams 1-6 and 1-7, which cannot be inserted into the beam main reinforcement hole 3b, and the joint panel 3 corresponding thereto, the conventional on-site concrete placement is performed. As a result, in the beam-column joint structure 10, it is not possible to eliminate the construction site for on-site concrete placement.

本発明は上記の点に鑑みてなされたものであり、現場でのコンクリート打設を不必要にすることが可能なＰＣ柱梁の接合構造、この接合構造を含んだ柱梁架構構造、およびＰＣ柱梁の接合方法を提供することを目的とする。 The present invention has been made in view of the above points, and a PC beam-column joint structure that can eliminate the need for on-site concrete placement, a column beam frame structure including the joint structure, and a PC. and to provide a bonding how the beam-column.

なお、図６（ａ）に示す構築途中の状態は、前述の図５（ｈ）と同じであり、すなわち、この状態までは、図５にて説明した手順と同手順で構築され、その後は、次のようにして構築される。   The state in the middle of construction shown in FIG. 6A is the same as that in FIG. 5H described above, that is, up to this state, it is constructed in the same procedure as described in FIG. It is constructed as follows.

先ず、図６（ｂ）に示すように、ＰＣ梁１−３、１−４の前方に、仕口パネル３−４、３−５をそれぞれ配置する。そして、各仕口パネル３−４、３−５を後方へ水平移動させ、当該水平移動の際に、各梁主筋孔３ｂに梁主筋１ａを挿入して、各ＰＣ梁１−３、１−４に仕口パネル３−４、３−５を接続し、図６（ｃ）に示す接続状態にする。ちなみに、ＰＣ柱４−６上に設置すべき仕口パネル３−６については、後で設置する。   First, as shown in FIG.6 (b), the joint panels 3-4 and 3-5 are each arrange | positioned ahead of PC beam 1-3, 1-4. And each joint panel 3-4, 3-5 is horizontally moved back, and in the case of the said horizontal movement, the beam main reinforcement 1a is inserted in each beam main reinforcement hole 3b, and each PC beam 1-3,1- 4 are connected to the connection panels 3-4 and 3-5, and the connection state shown in FIG. Incidentally, the joint panel 3-6 to be installed on the PC pillar 4-6 will be installed later.

次に、図６（ｃ）及び図６（ｄ）に示すように、仕口パネル３−４と仕口パネル３−５との間にＰＣ梁１１を設置するが、ここで、本第１実施形態に係る柱梁接合構造にあっては、予め、図１０の水平断面図に示す２種類のＰＣ梁１１、１３が用意されている。すなわち、両端部に梁主筋連結用継手１２が埋入されたＰＣ梁１１と、一方の端部からは梁主筋１ａが突出しているとともに他方の端部には梁主筋連結用継手が埋入されたＰＣ梁１３とが用意されている。なお、梁主筋連結用継手１２は、外周に凹凸部を有する短尺の鞘管であり、その内側の端部には、ＰＣ梁１１、１３内に埋入された梁主筋１ａの一端が挿入されている。   Next, as shown in FIG. 6C and FIG. 6D, the PC beam 11 is installed between the joint panel 3-4 and the joint panel 3-5. In the column beam connection structure according to the embodiment, two types of PC beams 11 and 13 shown in the horizontal sectional view of FIG. 10 are prepared in advance. That is, the PC beam 11 in which the beam main bar coupling joint 12 is embedded at both ends, and the beam main bar 1a protrudes from one end and the beam main bar coupling is embedded in the other end. PC beam 13 is prepared. The beam main bar coupling joint 12 is a short sheath pipe having an uneven portion on the outer periphery, and one end of the beam main bar 1a embedded in the PC beams 11 and 13 is inserted into the inner end of the pipe. ing.

そして、仕口パネル３−４と仕口パネル３−５との間には、図６（ｃ）及び図６（ｄ）に示すように、前者のＰＣ梁１１が上方から落とし込まれて介挿され、この状態でＰＣ梁１１の左端部が、左側の仕口パネル３−４に接合される。すなわち、図６（ｄ）のVIIａ部を拡大して図７（ａ）に示すように、前記仕口パネル３−４の梁主筋孔３ｂの左端からは、例えば鍔状の定着具５ｂを左端に備えた中継筋５ａが挿入される。そして、図７（ｂ）に示すように、この梁主筋孔３ｂの右端から突出する前記中継筋５ａは、前記ＰＣ梁１１の前記梁主筋連結用継手１２の内部に達するとともに、この時には、前記定着具５ｂは、仕口パネル３−４内に位置している。そして、仕口パネル３−４の外表面と梁主筋孔３ｂとを連通するグラウト注入孔（不図示）からグラウトが注入されることで、前記中継筋５ａは梁主筋孔３ｂおよび前記梁主筋連結用継手１２に定着され、これによって、ＰＣ梁１１の左端部は、左側の仕口パネル３−４に接合される。   As shown in FIGS. 6C and 6D, the former PC beam 11 is dropped from above between the joint panel 3-4 and the joint panel 3-5. In this state, the left end portion of the PC beam 11 is joined to the left joint panel 3-4. That is, as shown in FIG. 7 (a) by enlarging the VIIa portion of FIG. 6 (d), from the left end of the beam main reinforcement hole 3b of the joint panel 3-4, for example, a hook-shaped fixing tool 5b is connected to the left end. The relay bar 5a prepared for is inserted. As shown in FIG. 7 (b), the relay bar 5a protruding from the right end of the beam main bar hole 3b reaches the inside of the beam main bar coupling joint 12 of the PC beam 11, and at this time, The fixing tool 5b is located in the joint panel 3-4. Then, grout is injected from a grout injection hole (not shown) that connects the outer surface of the joint panel 3-4 and the beam main reinforcement hole 3b, so that the relay reinforcement 5a is connected to the beam main reinforcement hole 3b and the beam main reinforcement connection. By fixing to the joint 12 for use, the left end of the PC beam 11 is joined to the left joint panel 3-4.

一方、図６（ｅ）および図６（ｆ）に示すように、前記ＰＣ梁１１の右端部は、仕口パネル３−５に接合されるが、この接合は、後者のＰＣ梁１３の前記仕口パネル３−５への接合と組み合わされて次のようにして行われる。すなわち、図６（ｅ）のVIIIａ部を拡大して図８（ａ）に示すように、前記仕口パネル３−５の右側方には、前記ＰＣ梁１３が配置される。そして、この位置から当該ＰＣ梁１３が左方へ水平移動される際に、その左端部から突出している梁主筋１ａが、前記仕口パネル３−５の梁主筋孔３ｂの右端から挿入される。その結果、図８（ｂ）に示すように梁主筋１ａの先端は、前記梁主筋孔３ｂの左端から突出して前記ＰＣ梁１１の梁主筋連結用継手１２の内部に達する。そして、仕口パネル３−５の外表面と梁主筋孔３ｂとを連通するグラウト注入孔（不図示）からグラウトが注入されることで、前記梁主筋１ａが梁主筋孔３ｂ及び前記梁主筋連結用継手１２に定着され、これによって、ＰＣ梁１１の右端部は仕口パネル３−５に接合されると同時に、ＰＣ梁１３の左端部も前記仕口パネル３−５に接合される。   On the other hand, as shown in FIG. 6 (e) and FIG. 6 (f), the right end portion of the PC beam 11 is joined to the joint panel 3-5. It is carried out as follows in combination with joining to the joint panel 3-5. That is, as shown in FIG. 8A by enlarging the VIIIa portion of FIG. 6E, the PC beam 13 is arranged on the right side of the joint panel 3-5. When the PC beam 13 is horizontally moved to the left from this position, the beam main reinforcing bar 1a protruding from the left end is inserted from the right end of the main beam hole 3b of the joint panel 3-5. . As a result, as shown in FIG. 8B, the tip of the beam main reinforcing bar 1a protrudes from the left end of the beam main reinforcing bar hole 3b and reaches the inside of the beam main bar connecting joint 12 of the PC beam 11. Then, a grout is injected from a grout injection hole (not shown) that connects the outer surface of the joint panel 3-5 and the beam main reinforcement hole 3b, so that the beam main reinforcement 1a is connected to the beam main reinforcement hole 3b and the beam main reinforcement connection. By fixing to the joint 12, the right end of the PC beam 11 is joined to the joint panel 3-5, and at the same time, the left end of the PC beam 13 is joined to the joint panel 3-5.

最後に、図６（ｆ）〜図６（ｈ）に示すように、未設置であった右前のＰＣ柱４−６上に仕口パネル３−６を設置するが、この時には、図６（ｆ）に示すように前記ＰＣ梁１３の右端部からは梁主筋１ａが突出していないので、前記仕口パネル３−６は、物理的に干渉することなく前方へ水平移動させることができて、もって、仕口パネル３−６の梁主筋孔３ｂの後端からＰＣ梁１−５の梁主筋１ａが挿入されてＰＣ梁１−５に仕口パネル３−６が接合される。   Finally, as shown in FIG. 6 (f) to FIG. 6 (h), the splicing panel 3-6 is installed on the front right PC pillar 4-6, which has not been installed. As shown in f), since the main beam 1a does not protrude from the right end portion of the PC beam 13, the joint panel 3-6 can be horizontally moved forward without physical interference, Accordingly, the main beam 1a of the PC beam 1-5 is inserted from the rear end of the main beam hole 3b of the joint panel 3-6, and the joint panel 3-6 is joined to the PC beam 1-5.

そして、残るＰＣ梁１３の右端部と仕口パネル３−６との接合は、前述した前記ＰＣ梁１１の左端部の接合と同じようにしてなされる。すなわち、図６（ｇ）のIXａ部を拡大して図９（ａ）に示すように、仕口パネル３−６の梁主筋孔３ｂの右端から中継筋５ａが挿入される。そして、図９（ｂ）に示すように、この梁主筋孔３ｂの左端から突出する中継筋５ａは前記ＰＣ梁１３の前記継手１２の内部に達するとともに、この時には、中継筋５ａの右端の定着具５ｂは、仕口パネル３−６内に位置している。そして、仕口パネル３−６の外表面と梁主筋孔３ｂとを連通するグラウト注入孔（不図示）からグラウトが注入されることで、前記中継筋５ａは梁主筋孔３ｂおよび前記梁主筋連結用継手１２に定着され、これによって、ＰＣ梁１３の右端部は、右側の仕口パネル３−５に接合される。   And the joining of the right end part of the remaining PC beam 13 and the joint panel 3-6 is made in the same manner as the joining of the left end part of the PC beam 11 described above. That is, as shown in FIG. 9A by enlarging the IXa portion of FIG. 6G, the relay bar 5a is inserted from the right end of the beam main bar hole 3b of the joint panel 3-6. 9B, the relay bar 5a protruding from the left end of the beam main hole 3b reaches the inside of the joint 12 of the PC beam 13, and at this time, the right end of the relay bar 5a is fixed. The tool 5b is located in the joint panel 3-6. Then, grout is injected from a grout injection hole (not shown) that connects the outer surface of the joint panel 3-6 and the beam main reinforcement hole 3b, so that the relay reinforcement 5a is connected to the beam main reinforcement hole 3b and the beam main reinforcement connection. The right joint of the PC beam 13 is bonded to the right side panel 3-5.

そして、この接合によって当該柱梁架構は完成し、もって、本第１実施形態に係る柱梁接合構造を適用すれば、現場でのコンクリート打設を全く行わずに柱梁架構を完成させることが可能となる。   Then, by this joining, the column beam frame is completed. Therefore, if the column beam junction structure according to the first embodiment is applied, the column beam frame can be completed without any concrete placement on site. It becomes possible.

ちなみに、この第１実施形態においては、請求項３に係るＰＣ柱梁の接合構造は、図７に示した仕口パネル３−４とＰＣ梁１１との接合に適用されている。つまり、前記仕口パネル３−４およびＰＣ梁１１が、それぞれに、請求項３記載の第１ＰＣ部材および第２ＰＣ部材に相当している。   Incidentally, in the first embodiment, the PC column beam joint structure according to claim 3 is applied to the joint between the joint panel 3-4 and the PC beam 11 shown in FIG. That is, the joint panel 3-4 and the PC beam 11 correspond to a first PC member and a second PC member according to claim 3, respectively.

また、請求項１に係るＰＣ柱梁の接合構造は、図８に示した仕口パネル３−５と、ＰＣ梁１１およびＰＣ梁１３との接合に適用されている。つまり、前記仕口パネル３−５、ＰＣ梁１３、およびＰＣ梁１１が、それぞれに、請求項１記載の第１ＰＣ部材、第２ＰＣ部材、および第３ＰＣ部材に相当している。   Further, the PC column beam joint structure according to claim 1 is applied to the joint of the joint panel 3-5 shown in FIG. That is, the joint panel 3-5, the PC beam 13, and the PC beam 11 correspond to the first PC member, the second PC member, and the third PC member, respectively, according to claim 1.

図１１は、本発明の第２実施形態に係る柱梁接合構造の施工手順を説明するための柱梁架構の上面視概略図である。また、図１２は、図１１中のXIIａ部およびXIIｂ部を一部上面視で示す水平断面図である。   FIG. 11 is a top view schematic diagram of a column beam frame for explaining a procedure for constructing the column beam connection structure according to the second embodiment of the present invention. FIG. 12 is a horizontal cross-sectional view partially showing the XIIa portion and the XIIb portion in FIG. 11 in a top view.

なお、第１実施形態との相違点は、図８を用いて説明した、仕口パネル３−５を介してＰＣ梁１３とＰＣ梁１１とを接合する接合構造に在って、その他の接合構造は、第１実施形態と同じである。従って、図１１は、前述の図６（ｄ）の構築途中の状態から示しており、この状態までは前述と同手順で構築され、その後は次のようにして構築される。   The difference from the first embodiment lies in the joint structure for joining the PC beam 13 and the PC beam 11 via the joint panel 3-5 described with reference to FIG. The structure is the same as in the first embodiment. Therefore, FIG. 11 shows the state in the middle of the construction shown in FIG. 6 (d) described above. Up to this state, construction is performed in the same procedure as described above, and thereafter, construction is performed as follows.

先ず、第２実施形態に係る柱梁接合構造においては、前述のＰＣ梁１３の代わりに、両端部に梁主筋連結用継手１２が埋入されたＰＣ梁１１（図１０（ａ）を参照）が予め用意されている。そして、当該柱梁接合構造は、既に仕口パネル３−５の左脇に配置されたＰＣ梁１１の右端部と、前記ＰＣ梁１３の代わりに右脇に配置されたＰＣ梁１１の左端部との両者を、それぞれ前記仕口パネル３−５に接合する。   First, in the column beam connection structure according to the second embodiment, instead of the PC beam 13 described above, a PC beam 11 in which beam main bar coupling joints 12 are embedded at both ends (see FIG. 10A). Are prepared in advance. The column beam connection structure includes a right end portion of the PC beam 11 already arranged on the left side of the joint panel 3-5 and a left end portion of the PC beam 11 arranged on the right side instead of the PC beam 13. Are joined to the joint panel 3-5.

すなわち、図１１（ａ）の状態においては、仕口パネル３−５の左脇には既にＰＣ梁１１が配置されているが、その右端部は未だ仕口パネル３−５に接合されていない。そして、図１１（ｂ）のXIIａ部を拡大して図１２（ａ）に示すように、仕口パネル３−５の梁主筋孔３ｂの右端から中継筋５ｃが挿入され、これによって、図１２（ｂ）に示すように、この梁主筋孔３ｂの左端から突出する前記中継筋５ｃの左端が前記ＰＣ梁１１の前記梁主筋連結用継手１２の内部に達するとともに、前記中継筋５ｃの右端は、前記梁主筋孔３ｂの右端から突出した状態になる。次に、図１２（ａ）に示すように、仕口パネル３−５の右側方に、もう一つのＰＣ梁１１が配置され、この位置から前記ＰＣ梁１１が左方へ水平移動される際に、その左端部の前記梁主筋連結用継手１２に前記中継筋５ｃの右端が挿入されてその内部に達する。そうしたら、仕口パネル３−５の外表面と梁主筋孔３ｂとを連通するグラウト注入孔（不図示）からグラウトが注入されることで、前記中継筋５ｃが梁主筋孔３ｂ及び前記梁主筋連結用継手１２に定着され、これによって、仕口パネル３−５の左脇に位置するＰＣ梁１１の右端部は、仕口パネル３−５に接合されると同時に、右脇に位置するＰＣ梁１１の左端部も前記仕口パネル３−５に接合される。   That is, in the state of FIG. 11A, the PC beam 11 is already arranged on the left side of the joint panel 3-5, but the right end thereof is not yet joined to the joint panel 3-5. . Then, as shown in FIG. 12 (a) by enlarging the XIIa portion of FIG. 11 (b), the relay bar 5c is inserted from the right end of the beam main reinforcement hole 3b of the joint panel 3-5, whereby FIG. As shown in (b), the left end of the relay bar 5c protruding from the left end of the beam main bar hole 3b reaches the inside of the beam main bar coupling joint 12 of the PC beam 11, and the right end of the relay bar 5c is In this state, the beam main bar hole 3b protrudes from the right end. Next, as shown in FIG. 12A, another PC beam 11 is arranged on the right side of the joint panel 3-5, and when the PC beam 11 is horizontally moved from this position to the left side, In addition, the right end of the relay bar 5c is inserted into the beam main bar coupling joint 12 at the left end and reaches the inside thereof. Then, grout is injected from a grout injection hole (not shown) that connects the outer surface of the joint panel 3-5 and the beam main reinforcement hole 3b, so that the relay reinforcement 5c becomes the beam main reinforcement hole 3b and the beam main reinforcement. The right end portion of the PC beam 11 which is fixed to the coupling joint 12 and is located on the left side of the joint panel 3-5 is joined to the joint panel 3-5 and at the same time the PC located on the right side. The left end portion of the beam 11 is also joined to the joint panel 3-5.

なお、この第２実施形態では、請求項２に係るＰＣ柱梁の接合構造が適用されており、すなわち、前記仕口パネル３−５、および二つのＰＣ梁１１、１１が、それぞれに、請求項１記載の第１ＰＣ部材、第２ＰＣ部材、および第３ＰＣ部材に相当している。   In addition, in this 2nd Embodiment, the connection structure of the PC pillar beam which concerns on Claim 2 is applied, ie, the said joint panel 3-5 and the two PC beams 11 and 11 are each charged. This corresponds to the first PC member, the second PC member, and the third PC member according to Item 1.

図１３は、本発明の第３実施形態に係る柱梁接合構造の水平断面図である。同図の上段に示すように、第１実施形態に係る仕口パネル３は、その平面寸法がＰＣ柱４の平面寸法とほぼ同じであったが、同図の中段および下段に示すように、第３実施形態に係る仕口パネル３’、３’’は、その側端面が、前記ＰＣ梁４の方へ延出している点で相違する。   FIG. 13 is a horizontal sectional view of a beam-column joint structure according to a third embodiment of the present invention. As shown in the upper part of the figure, the joint panel 3 according to the first embodiment has a plane dimension substantially the same as the plane dimension of the PC pillar 4, but as shown in the middle and lower parts of the figure, The joint panels 3 ′ and 3 ″ according to the third embodiment are different in that the side end surfaces extend toward the PC beam 4.

すなわち、前記仕口パネル３’、３’’の四つの側端面のうち、梁主筋孔３ｂが設けられる側端面の一方又は両方には、ＰＣ梁１１とほぼ同じ鉛直断面形状の梁状部３ｆが一体に延出形成されている。そして、この梁状部３ｆに、前記ＰＣ梁１１の端部が突き合わされて接合される。   That is, of the four side end surfaces of the joint panels 3 ′ and 3 ″, one or both of the side end surfaces where the beam main reinforcing hole 3b is provided are provided with a beam-like portion 3f having the same vertical cross-sectional shape as the PC beam 11. Are integrally formed. Then, the end of the PC beam 11 is abutted and joined to the beam-shaped portion 3f.

なお、このように梁状部３ｆを予め一体に設けている理由は、仕口パネル３’、３’’とＰＣ梁１１との接合部ｊをＰＣ柱４から遠ざけるためである。すなわち、一般に、柱に接合された梁においては、前記柱に近い部分ほど大きな曲げ応力が作用する一方、前記接合部ｊは通常、他の部分に比べて強度的に弱い。よって、前記接合部ｊを柱の近傍から遠ざけておけば、柱梁接合構造の強度を実質的に高めることができるためである。ちなみに、遠ざける目安としては、塑性ヒンジが形成される領域に前記接合部ｊを入らないようにする等が挙げられる。   The reason why the beam-like portion 3f is integrally provided in advance is to keep the joint j between the joint panels 3 ', 3' 'and the PC beam 11 away from the PC column 4. That is, in general, in a beam joined to a column, a greater bending stress acts on a portion closer to the column, while the joint j is usually weaker than other portions. Therefore, if the joint j is kept away from the vicinity of the column, the strength of the column beam connection structure can be substantially increased. By the way, as a guide for moving away, it is possible to prevent the joint j from entering the region where the plastic hinge is formed.

以上、本発明の実施形態について説明したが、本発明は、かかる実施形態に限定されるものではなく、その要旨を逸脱しない範囲で以下に示すような変形が可能である。   As mentioned above, although embodiment of this invention was described, this invention is not limited to this embodiment, The deformation | transformation as shown below is possible in the range which does not deviate from the summary.
