Description
本発明はＰＣ壁板の接合方法及びこの方法を用いてＰＣ壁板が接合されてなる壁構造に関する。 The present invention relates to a method for joining PC wall plates and a wall structure in which PC wall plates are joined using this method.
従来より、建物の壁を構築する方法として、フルＰＣ壁板を用いた方法が広く用いられている。このようなフルＰＣ壁板を用いた方法では、フルＰＣ壁板同士の端部より鉄筋を突出させておき、隣接するフルＰＣ壁板の壁筋を重ね継手又は機械式継手などにより継手し、これらフルＰＣ壁板の間にコンクリートを打設することによりフルＰＣ壁板同士を接合している（例えば、特許文献１参照）。
ここで、隣接するフルＰＣ壁板を、一方のフルＰＣ壁板の横筋に接合端面に鉄筋挿入口が端面に開口するように機械式継手を接続しておき、また、他方のフルＰＣ壁板の横筋を接合端面より突出させておき、他方のフルＰＣ壁板を、横筋の接合端面より突出した部分が機械式継手内に挿入されるように水平に移動して建て込み、機械式継手内にグラウトを充填することによりフルＰＣ壁板を接合することが考えられる。 Here, an adjacent full PC wall plate is connected to a lateral line of one full PC wall plate with a mechanical joint so that a reinforcing bar insertion opening opens to the end surface, and the other full PC wall plate is also connected to the other full PC wall plate. The horizontal bars of the horizontal bars are protruded from the joint end face, and the other full PC wall plate is horizontally moved so that the part protruding from the joint end face of the horizontal bars is inserted into the mechanical joint. It is conceivable to join the full PC wallboard by filling grout with slag.
しかしながら、スラブやフルＰＣ壁板の上面、梁の下面には、新たに建て込まれたフルＰＣ壁板との接合のために接合鉄筋が突出しており、この接合鉄筋が障害となるため、フルＰＣ壁板を水平に移動させて建て込むことができない。このため、上記のように、フルＰＣ壁板間にコンクリートを現場打ちする部分を設け、この部分においてフルＰＣ壁板の壁筋を継手していた。 However, on the upper surface of the slab or full PC wall plate and the lower surface of the beam, the joint rebar protrudes for joining with the newly built full PC wall plate. The PC wallboard cannot be built horizontally. For this reason, as described above, a portion for in-situ concrete is provided between the full PC wall plates, and the wall bars of the full PC wall plates are jointed at this portion.
このようにフルＰＣ壁板間のコンクリートを現場打設しなければならないため、型枠の設置作業、コンクリートの打設作業、及び脱型作業等を行う必要があり、非常に手間がかかり、また、施工期間が長期化していた。 In this way, the concrete between full PC wallboards must be cast in the field, so it is necessary to perform the work of installing the formwork, placing the concrete, and removing the mold. The construction period was prolonged.
本発明は、上記の問題に鑑みなされたものであり、その目的は、現場におけるコンクリート打設作業を無くすべく、フルＰＣ壁板を水平方向に建て込み可能にすることである。 The present invention has been made in view of the above problems, and an object of the present invention is to enable a full PC wall board to be installed in the horizontal direction so as to eliminate the concrete placing work on site.

また、前記コンクリート部材は、ＰＣ壁板であって、前記コンクリート部材の接合鉄筋は、前記ＰＣ壁板の壁筋又は前記ＰＣ壁板の壁筋の近傍に埋設され、前記壁筋と重ね継手を形成する鉄筋であってもよい。 Further , the concrete member is a PC wall board, and the joint reinforcing bar of the concrete member is embedded in the vicinity of the wall bar of the PC wall board or the wall bar of the PC wall board, and the wall bar and the lap joint are connected. It may be a reinforcing bar to be formed.
また、前記鉄筋収容孔は、前記ＰＣ壁板を接合方向に貫通するように形成されており、前記壁筋は、前記壁筋を前記鉄筋収容孔内を挿通させることにより前記接合端面から突出してもよい。 The reinforcing bar accommodation hole is formed so as to penetrate the PC wall plate in the joining direction, and the wall reinforcement protrudes from the joining end surface by inserting the wall reinforcement into the reinforcing bar accommodation hole. Also good.
本発明によれば、ＰＣ壁板に部材の接合端面から突出可能に壁筋が設けられ、この壁筋を突出させてＰＣ壁板、梁、又はスラブの接合鉄筋と継手するため、ＰＣ壁板、梁又はスラブに接合端面から接合鉄筋を突出させる必要がなくなる。これにより、フルＰＣ壁板を水平方向に移動させて建て込むことができ、例えば、一対のフルＰＣ壁板の何れか一方の側面に機械式継手を埋設し、他方のフルＰＣ壁板の側面より壁筋を突出させておき、何れか一方のフルＰＣ壁板を側面より突出した壁筋の先端が機械式継手内に挿入されるように水平方向に移動させて建て込み、一対のフルＰＣ壁板の壁筋を機械式継手により継手することができる。これにより、現場においてコンクリートを打設する必要がなくなり、施工性を向上することができる。 According to the present invention, a wall bar is provided on the PC wall plate so as to protrude from the joint end surface of the member, and the wall wall bar is projected to be coupled to the PC wall plate, the beam, or the joint bar of the slab. In addition, it is not necessary to project the joint rebar from the joint end face to the beam or slab. Thereby, a full PC wall board can be moved and built in a horizontal direction. For example, a mechanical joint is embedded in one side of a pair of full PC wall boards, and the side of the other full PC wall board is built. A pair of full PCs are made by protruding the wall bars and moving one of the full PC wall plates horizontally so that the tip of the wall bars protruding from the side surface is inserted into the mechanical joint. The wall bars of the wallboard can be joined by a mechanical joint. Thereby, it is not necessary to place concrete on site, and workability can be improved.

Further, when a wall is constructed by connecting full PC wall plates, it is not always necessary to use any of the above-mentioned full PC wall plate joining methods, and a plurality of methods may be used in combination.
Moreover, in the wall construction method described with reference to FIGS. 6 to 15 described above, the column and the full PC wall plate are joined to the joint reinforcing bar embedded in the column and the horizontal bar of the full PC wall plate, The grout is filled and joined between the full PC wallboard and the column, but this is not a limitation, and the reinforcing bars of the column are omitted, and the horizontal bars of the full PC wallboard are not joined to the column reinforcement. It is good also as only filling grout between a full PC wall board and a pillar. In this case, a shear key may be provided on the joining end face of the column or full PC wall board.

It is also possible to apply the joining method to a joining method of full PC wall plates adjacent in the horizontal direction. In such a case, the state where FIGS. 16 to 22 are rotated by 90 degrees corresponds to the case where the full PC wall plates adjacent in the horizontal direction are joined. Thus, the joint method of the horizontal stripe of the full PC wall board adjacent in a horizontal direction is not ask | required.
また、本実施形態では、ＰＣ壁板を水平方向に移動させて建て込む場合について説明したが、これに限らず、ＰＣ壁板を鉛直方向に移動させて建て込むことも可能である。かかる場合には、上記図６〜図１５を参照して説明した壁の構築方法における上下のフルＰＣ壁板の接合方法及び図１６〜図２２を参照して説明した上下方向に隣接するフルＰＣ壁板の接合方法を水平方向に隣接するフルＰＣ壁板の接合方法に適用すればよい（これらの図を９０度回転させた状態）。なお、上記の各実施形態における水平方向に隣接するフルＰＣ壁板の横筋の継手方法と同様に、上下方向に隣接するフルＰＣ壁板の縦筋の継手方法は問わない。 Moreover, although this embodiment demonstrated the case where the PC wall board was moved and built in a horizontal direction, not only this but a PC wall board can also be moved and built in a vertical direction. In such a case, the method of joining the upper and lower full PC wall plates in the wall construction method described with reference to FIGS. 6 to 15 and the full PC adjacent in the vertical direction described with reference to FIGS. What is necessary is just to apply the joining method of a wall board to the joining method of the full PC wall board adjacent to a horizontal direction (The state which rotated these figures 90 degree | times). In addition, the joint method of the vertical stripe of the full PC wall board adjacent to an up-down direction is not ask | required similarly to the horizontal stripe joint method of the full PC wall board adjacent to the horizontal direction in said each embodiment.
また、上記の実施形態では、１階層分の壁を構築する場合について説明したが、これに限らず、図２５に示すように、複数階層に亘るような壁４１０を構築する場合にも本実施形態のフルＰＣ壁板の接合方法を適用することができる。このような場合には、フルＰＣ壁部材として、壁と梁の一部が一体となった梁つきのフルＰＣ壁板を用いてもよい。このような場合は、梁を構成するコンクリートは現場打ちとしても構わない。 In the above embodiment, the case of constructing a wall for one layer has been described. However, the present invention is not limited to this, and the present embodiment is also applied to the case of constructing a wall 410 extending over a plurality of layers as shown in FIG. The joining method of the form full PC wall board is applicable. In such a case, as a full PC wall member, a full PC wall plate with a beam in which a part of the wall and the beam are integrated may be used. In such a case, the concrete constituting the beam may be cast on-site.
