本発明は、コンクリート部材同士を連結するためのコンクリート部材の継手等に関する。 TECHNICAL FIELD The present invention relates to a joint of concrete members and the like for connecting concrete members together.

橋軸直角方向（橋幅方向）に並設された複数の主桁上にコンクリート部材としての例えば橋梁用コンクリートプレキャスト製の床版を架け渡し、橋軸方向に沿って隣り合う床版同士をコッター式継手と呼ばれる継手を用いて接続する床版接続工法が知られている（特許文献１参照）。
当該継手は、隣り合う各床版の端部側にそれぞれ設置された受部材と、互いに隣り合う各受部材を繋ぐ繋ぎ部材と、繋ぐ繋ぎ部材を受部材に固定するボルトとを備えた構成である。受部材は、繋ぎ部材に設けられた係合部が係合する係合受部を備えた係合受部と、床版のコンクリートに定着される例えば定着筋等の鋼材により形成された定着部とを備える。繋ぎ部材は、互いに隣り合う各床版の各端部にそれぞれ設置された受部材の各係合受部に係合する一対の係合部と、一対の係合部を繋ぐ連結部とを備える。
当該継手によれば、橋軸方向に沿って隣り合う各床版の端部にそれぞれ埋設された各係合受部の各係合受部内に繋ぎ部材の各係合部を挿入した後、係合受部内に嵌め込まれた係合部の固定部に形成されたボルト挿入孔にボルトを挿入し、各係合受部の底版に形成されたねじ孔にボルトを締結することによって、繋ぎ部材と係合受部とが固定され、当該継手により、互いに隣り合う各床版が接続される。 Floor slabs, such as concrete precast concrete for bridges, are laid over multiple main girders arranged in parallel in the direction perpendicular to the bridge axis (bridge width direction), and a cotter connects the floor slabs that are adjacent to each other along the bridge axis direction. A floor slab connection method is known in which joints called joints are used for connection (see Patent Document 1).
The joint includes a support member installed on the end side of each adjacent floor slab, a connection member connecting the support members adjacent to each other, and a bolt fixing the connection member to the support member. be. The receiving member includes an engagement receiving portion that engages with the engaging portion provided on the connecting member, and a fixing portion that is fixed to the concrete of the floor slab and is formed of a steel material such as a fixing bar. and The connecting member includes a pair of engaging portions that engage with the engagement receiving portions of the receiving members that are installed at the ends of the floor slabs that are adjacent to each other, and a connecting portion that connects the pair of engaging portions. .
According to this joint, after inserting each engagement portion of the connecting member into each engagement receiving portion of each engagement receiving portion embedded in the end portion of each floor slab that is adjacent along the bridge axis direction, By inserting a bolt into a bolt insertion hole formed in a fixing portion of the engagement portion fitted in the joint portion and fastening the bolt to a screw hole formed in the bottom plate of each engagement receiving portion, the connecting member and the The engagement receiving portion is fixed, and the floor slabs adjacent to each other are connected by the joint.

しかしながら、継手の製造誤差、床版の製作誤差や収縮量（反り）のばらつき、腐食防止のために継手に塗布されるエポキシ樹脂の塗布量のばらつき、床版架設時の施工誤差等によって、隣り合う各床版の端部に埋設された各係合受部同士の左右方向や上下方向のずれが生じる。このずれが大きい場合は、繋ぎ部材の係合部を係合受部の係合受部内に嵌め込むことが困難となり、繋ぎ部材と係合受部とを結合できなくなってしまう。また、繋ぎ部材の係合部を係合受部内に嵌め込むことができたとしても、係合受部内に嵌め込まれた係合部のボルト挿入孔と各係合受部の底版のねじ孔とが一致しなくなるため、ボルトを締結することができず、繋ぎ部材と係合受部とを結合できなくなってしまう。このように、繋ぎ部材と係合受部とを結合できない場合、当該継手部分で応力の伝達ができず、継手部分で損壊を招く恐れがある。
本発明は、隣り合う各コンクリート部材の端部に埋設された各受部材同士の左右方向や上下方向のずれが生じた場合であっても、受部材と繋ぎ部材とを結合できるコンクリート部材の継手等を提供する。 However, due to joint manufacturing errors, floor slab manufacturing errors and shrinkage (warp) variations, variations in the amount of epoxy resin applied to the joints to prevent corrosion, construction errors during floor slab erection, etc. The engagement receiving portions embedded in the ends of the mating floor slabs are misaligned in the left-right direction and the up-down direction. If this deviation is large, it becomes difficult to fit the engagement portion of the connecting member into the engagement receiving portion of the engagement receiving portion, and the connecting member and the engagement receiving portion cannot be connected. Further, even if the engaging portion of the connecting member can be fitted into the engagement receiving portion, the bolt insertion hole of the engaging portion fitted into the engagement receiving portion and the screw hole of the bottom plate of each engagement receiving portion do not match, the bolt cannot be fastened, and the connecting member and the engagement receiving portion cannot be connected. In this way, when the connecting member and the engagement receiving portion cannot be connected, stress cannot be transmitted at the joint portion, and there is a possibility that the joint portion may be damaged.
The present invention provides a concrete member joint capable of connecting a support member and a connecting member even when the support members embedded in the ends of adjacent concrete members are misaligned in the horizontal direction or the vertical direction. etc.

即ち、受部材２Ａ，２Ｂの凹部２１Ａ，２１Ｂの内壁面２８ａ，２８ｂと楔部材４とが互いに面接触する面を備えた構成とした。
尚、挿入部３１Ａ，３１Ｂの内面３１ａ，３１ｂ又は凹部２１Ａ，２１Ｂの内壁面２８ａ，２８ｂである傾斜面の傾斜角度と楔部材４の傾斜面４ａの傾斜角度とが同一傾斜角度でなくても、楔部材４による楔の機能が発揮されればよい。 Further, in the joint 1 of the present invention, the inclination angles of the inclined surfaces that are the inner surfaces 31a and 31b of the insertion portions 31A and 31B or the inner wall surfaces 28a and 28b of the recesses 21A and 21B and the inner surfaces 31a and 31b of the insertion portions 31A and 31B are Alternatively, the inclination angle of the inclined surface 4a of the wedge member 4, which contacts the inner wall surfaces 28a, 28b of the recesses 21A, 21B, is formed at the same inclination angle. 4 are in close contact with the inner surfaces 31a and 31b of the insertion portions 31A and 31B, or the inner wall surfaces 28a and 28b of the recess, so that the receiving members 2A and 2B and the connecting member 3 are firmly fixed. be able to maintain.
That is, the inner wall surfaces 28a, 28b of the recesses 21A, 21B of the receiving members 2A, 2B and the wedge member 4 are provided with surfaces that are in surface contact with each other.
It should be noted that even if the inclination angle of the inclined surfaces which are the inner surfaces 31a and 31b of the insertion portions 31A and 31B or the inner wall surfaces 28a and 28b of the recesses 21A and 21B and the inclination angle of the inclined surface 4a of the wedge member 4 are not the same. , the function of the wedge by the wedge member 4 should be exhibited.

また、本発明の継手１では、繋ぎ部材３の挿入部３１Ａや挿入部３１Ｂにおいて連結部３２を挟んで隣り合う左右一対の内面にそれぞれ対応するように、楔部材４，４を圧入する構成とした（図２，図３参照）ことにより、各受部材２Ａ，２Ｂと繋ぎ部材３との結合において、左右のバランスが良好な固定状態を維持できるようになる。 Further, in the joint 1 of the present invention, the wedge members 4, 4 are press-fitted so as to correspond to a pair of left and right inner surfaces adjacent to each other across the connecting portion 32 in the insertion portion 31A and the insertion portion 31B of the connecting member 3. By doing so (see FIGS. 2 and 3), it is possible to maintain a fixed state in which the receiving members 2A and 2B and the connecting member 3 are coupled with good left-right balance.

尚、各実施形態においては、繋ぎ部材３を凹部２１Ａ，２１Ｂの内底面２５ａ側に設置する際には、凹部２１Ａ，２１Ｂの内底面２５ａに図外のスペーサを設置しておいて、繋ぎ部材３の下面３ｕを当該スペーサの上に載せて繋ぎ部材３を橋軸方向Ｘに沿って移動可能な状態に設置してから楔部材４を挿入することにより、楔部材４と凹部２１Ａ，２１Ｂの内壁面と繋ぎ部材３の内面との密着性、及び、凹部２１Ａ，２１Ｂの内壁面と繋ぎ部材３の内面との密着性が向上し、継手１により、隣り合う床版１０，１０同士を強固に連結できるようになる。 In each embodiment, when installing the connecting member 3 on the side of the inner bottom surface 25a of the recesses 21A and 21B, a spacer (not shown) is placed on the inner bottom surface 25a of the recesses 21A and 21B so that the connecting member 3 is placed on the spacer and the joint member 3 is placed in a state in which it can move along the bridge axis direction X, and then the wedge member 4 is inserted, whereby the wedge member 4 and the recesses 21A and 21B are separated. The adhesion between the inner wall surface and the inner surface of the connecting member 3 and the adhesion between the inner wall surfaces of the recesses 21A and 21B and the inner surface of the connecting member 3 are improved, and the joint 1 strengthens the adjacent floor slabs 10 and 10. be able to connect to
