この発明は、ボックスカルバートを始め下水路用等に使
用されるコンクリート部材の連結工法に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for connecting concrete members used for sewers, including box culverts.
（従来の技術）
コンクリート部材の連結にＰＣ鋼棒を使用する場合には

ラーにより連結した後、鋼棒を緊張し部材を一体化する
方法が採用される。(Prior art) When using PC steel rods to connect concrete members, usually several members are lined up, the steel rods are inserted through them, and the steel rods are connected using couplers, and then the steel rods are tensioned to integrate the members. The method will be adopted.
しかじ鋼棒を緊張して連結する際、シースと鋼棒との誤
差により連結しようとする鋼棒同士がずれることがあり
、このためカプラーでの連結は難しくなる。鋼棒を・７
−スに通して連結を行なう方法は、鋼棒の軸線を一致さ
せることは困難であり一般に部材の製作には正確さが要
求される。When connecting steel rods under tension, the steel rods may become misaligned due to an error between the sheath and the steel rod, making it difficult to connect them with a coupler. Steel rod ・7
- In the method of connecting through steel rods, it is difficult to align the axes of the steel rods, and accuracy is generally required in the manufacture of the members.
また、数個の部材を一本の鋼棒で連結すると各部材の自
由度は低下し、大きな不同沈下に抵抗しきれなくなる。Furthermore, when several members are connected by a single steel rod, the degree of freedom of each member decreases, making it impossible to resist large uneven settlements.
そこで、部材内に連結部を設け、カプラーでの連結はこ
こで行なう等の手段により鋼棒のずれに対処する方法が
考え出されている。これは７−スと鋼棒との誤差による
場合の他、不同沈下にょる鋼棒の軸線の不一致にも適応
させるものであるが部材同士の連結ては大きな余裕は与
えられていない。Therefore, a method has been devised to deal with the misalignment of the steel rod by providing a connecting portion within the member and connecting with a coupler there. This is to accommodate not only the error between the base and the steel rod, but also the mismatch of the axes of the steel rod due to uneven settlement, but it does not allow for a large margin when connecting the members.
この発明は、鋼棒の軸線の不一致による作業の困難性を
解消し、不同沈下等の障害に抵抗させる目的でなされた

（問題点を解決するための手段）
本工法では隣合う部材毎に連結が行なえるようＰＣ鋼棒
はそれぞれの部材内に配置しておく。(Means for solving the problem) In this construction method, PC steel rods are arranged within each member so that adjacent members can be connected.
連結は各部材毎に１角度調節可能なカプラーにより行な
い軸線の不一致が生じた場合に、あるいは角度をつけて
敷設しようとする場合に対処できるようにする。The connection is made by a coupler that can be adjusted by one angle for each member, so that it is possible to deal with cases where misalignment of the axes occurs or when installing at an angle.
（実施例）
以下このコンクリート部材の連結工法を一実施例として
ボックスカルバートを示した図面に基づいて説明する。(Example) This method of connecting concrete members will be described below as an example based on a drawing showing a box culvert.
コンクリート部材１は部材内周の各隅に部材長よりやや
短いＰＣ鋼棒２を配置して製作されるＯＰＣＰＣ鋼棒２
にアンボンド加工したものを使用する。The concrete member 1 is an OPCPC steel rod 2 manufactured by arranging a PC steel rod 2 slightly shorter than the member length at each corner of the inner circumference of the member.
Use the one that has been unbonded.
部材１には、カプラー取付けのため鋼棒の両端部を切欠
き、連結部３を設けておく。In the member 1, a connecting portion 3 is provided by cutting out both ends of a steel rod for attaching the coupler.
カプラー４は荷重受は面４ａを曲面状に加工し座金５の
これに接する面もカプラーと枢着するよう同様に加工す

ラーの鋼棒挿通孔４ｂは鋼棒の径より大きく開け、特に
座金側を狭く、円錐台状に開けるのが好ましい。The load receiving surface 4a of the coupler 4 is machined into a curved shape, and the surface of the washer 5 in contact with this is similarly machined so as to be pivotally connected to the coupler. Its shape is preferably cylindrical or spherical. It is preferable that the steel rod insertion hole 4b of the coupler be opened larger than the diameter of the steel rod, and particularly narrow on the washer side and shaped like a truncated cone.
次に施工手順を第２図に基づいて説明する。Next, the construction procedure will be explained based on FIG. 2.

を繰り返し、部材を連結しておく。After laying the concrete member 1-1 manufactured as described above at a predetermined position, the steel bar end 2a on the already laid side and the steel bar end 2b of the already laid member 1-0 are tied together in the coupler 4. Then, connect the parts. Next, the steel rod 2b on the side in the direction in which the laying progresses is tightened and temporarily fixed to the connecting part side wall 3a with a Nantes. This steel rod end 2b is passed through the coupler insertion hole 4b, and the steel rod end 2a of the adjacent member 1-2 is also passed through the same coupler from the opposite side and tightened together with nuts to connect the members. Furthermore, the other end 2b of the steel rod is fixed to the connecting part side wall 3a under tension, and then the steel rod end 2a of the installed member is
Insert it into the coupler and tighten it. Repeat this procedure to connect the parts.

なる。(Effects of the invention) In this construction method, PC steel bars are buried in individual members, and a coupler that can adjust the angle is used for connection, so even if misalignment of the axes occurs during installation, this will not be a problem. , it can fully cope with uneven subsidence. In other words, the load receiver of the coupler has a flat or curved shape, and the insertion hole is large, so that the connection between the members is balanced.
