領で行われる。
When laying concrete members such as box culverts using prestressed steel bars, the couplers are usually used to connect the prestressed steel bars by laying multiple concrete members, inserting the prestressed steel bars through them, tensioning them, and then facing each other. This is done by connecting PC steel rods with couplers.
ところが、従来のカプラーはPC鋼棒に直接螺

対向するPC鋼棒の軸線が一致しない場合にはカ
プラーでの連結が困難となり、部材の製作、及び
鋼棒の配置は正確に行うことが要求される。 However, since conventional couplers have a structure that screws directly onto the PC steel rod, if the axes of the opposing PC steel rods do not match due to errors with the sheath, it becomes difficult to connect them with the coupler, making it difficult to manufacture the parts. and steel rods must be placed accurately.

とで対応することもできるが、カプラーの設置は
難しく、PC鋼棒の使用には適さない。 In addition, conventional couplers can only be used when laying concrete members in a straight line or with a slight curvature to the extent that the effect of the PC steel bar is not lost; There is an inconvenience in that it is not effective when it is necessary to install a Especially when laying with a small curvature, it is possible to use angled concrete members, but it is difficult to install couplers and it is not suitable for using prestressed steel bars.

In this invention, the contact surface between the inner circumferential surface of the opening formed for fastening the nut and the washer, that is, the load receiving surface, for fixing the PC steel bar in the main body is formed into a curved shape, and at the same time, the opening is opened at both ends of the opening. By making the insertion hole for the prestressed steel rod larger than the diameter of the prestressed steel rod, it is possible to connect the prestressed prestressed steel rods of adjacent concrete members at an angle. It absorbs errors and supports connections between concrete members laid at preset angles.

カプラー１の本体には第１図、第２図に示すよ
うにナツト５の緊結のための開口が形成され、こ
の開口に連続して両端に挿通孔３，３が明けられ
ている。 As shown in FIGS. 1 and 2, an opening for fastening a nut 5 is formed in the main body of the coupler 1, and insertion holes 3, 3 are formed at both ends of the coupler 1 in continuation with this opening.
開口の内周の、座金４が接触する荷重受け面２

面も曲面状の形状をし、座金４は荷重受け面２に
常に接触しながら、カプラー１の軸に対して任意
の角度を向く。荷重受け面２は凹面に、座金４は
凸面に形成される。 Load receiving surface 2 on the inner periphery of the opening that the washer 4 contacts
are formed in a curved shape, and the contact surface of the washer 4 also has a curved shape with the same curvature, and the washer 4 always contacts the load receiving surface 2 while facing at an arbitrary angle with respect to the axis of the coupler 1. The load receiving surface 2 is formed into a concave surface, and the washer 4 is formed into a convex surface.
第１図は荷重受け面２を円筒状の曲面に形成し
た場合、第３図は球状の曲面に形成した場合であ
る。 FIG. 1 shows a case where the load receiving surface 2 is formed into a cylindrical curved surface, and FIG. 3 shows a case where it is formed into a spherical curved surface.

3 is opened larger than the diameter of the PC steel rods 6, 6, and the PC steel rod 6, like the washer 4, can be connected to the coupler 1 at any angle within the range of the diameter of the insertion hole 3.
この挿通孔３の形状は第６図に示すようにPC
鋼棒６がカプラー１に対し、ナツト５の位置を中
心に角度が付くことから、外側の径が大きい円錐
台形が最も合理的である。 The shape of this insertion hole 3 is as shown in Figure 6.
Since the steel rod 6 forms an angle with respect to the coupler 1 around the position of the nut 5, a truncated conical shape with a large outer diameter is most rational.
