Traditionally, as a joint structure for concrete structures,
As announced in Japanese Utility Model Publication No. 56-6564, on the inside of the intermediate plate of the U-shaped joint fitting,
A thick washer with an arched cross section is arranged, the planes on both sides of the washer are brought into contact with the inner surface of the intermediate plate of the joint fitting, bolt insertion holes are provided in the center of the intermediate plate and the center of the washer, and the A structure is known in which a joint fitting containing a washer is embedded and fixed in a concrete structure, and an opening for bolt fastening operation is provided on the back side of the washer in the concrete structure.

In the case of the conventional joint structure for concrete structures, the center of the planes on both sides of the washer is offset from the intersection of the intermediate plate and both side plates of the U-shaped joint fitting toward the center of the intermediate plate. Therefore, if an external force is applied that causes the concrete structures to move apart from each other after inserting bolts through the washers and the intermediate plate of mutually joined concrete structures and tightening them, the U-shaped Excessive shearing force and bending moment act on the intermediate plate in the joint fitting, and as a result, the intermediate plate is significantly deformed.

造物の継手の製作も煩雑である。 In addition, in the case of the above-mentioned conventional joint structure for concrete structures, the joint metal fittings are U-shaped and are not reinforced, so the strength of the joint metal fittings is weak. Then, concrete is poured using the formwork for forming the opening, and after the concrete has hardened,
Manufacturing joints for concrete structures is also complicated because the formwork needs to be removed.

The bolt tensile force is distributed and transmitted by the tied arch effect formed by the joint plate 2 and the arch-shaped plate 4. That is, in the case of the first embodiment and the second embodiment, the tensile force of the bolt is not transmitted to the anchor reinforcing steel by the bending rigidity of the joint plate as in the conventional joint, but by transmitting the tensile force of the bolt to the anchor reinforcing bar by using the bending rigidity of the joint plate. Since the fulcrum is located at the inner corner of the U-shaped joint plate 2, the tensile force of the bolt can be transmitted with high rigidity by forming a tied arch in which the joint plate 2 acts as a tension suppressor. It is something.

According to this invention, an arc-shaped steel arch-shaped plate 4 having a bolt insertion hole 3 in the center is placed inside a U-shaped steel joint plate 2 having a bolt insertion hole 1 in the center. and both ends of the arch-shaped plate 4 are engaged with the inner corners of the intersections of the intermediate plate and each flange in the joint plate 2 and are coupled by welding, so that the arch-shaped plate 4 and the joint plate 2 are connected by welding. A space is provided between the intermediate plate and the arch-shaped plate 4 so that the thickness center extension line of the arch-shaped plate 4 is the same as the thickness center extension line of the intermediate plate and the flange thickness center extension line of the U-shaped joint plate 2. Since the tied arch is configured by being arranged near the intersection, the joint plate 2 only needs to mainly resist tensile force, and therefore the joint plate 2
Compared to the case where the joint plate 2 resists bending,
The arch-shaped plate 4 can resist larger loads with less deformation than a flat steel plate due to the arch effect. A joint fitting 6 to which a reinforcing bar 5 is fixed, which is made up of a joint plate 2, an arch-shaped plate 4, and an anchor reinforcing bar 5.
is embedded and fixed in the end of the reinforced concrete segment 7, so that a joint of reinforced concrete segments with high rigidity and high strength can be obtained economically.
