Various reinforcing steel materials have been proposed in which joints are pre-bonded to the reinforcing steel frame of segments to facilitate the connection of segments, but since there is no means to secure bolt boxes in the joint fittings, bolts cannot be easily connected when forming segments. It is difficult to remove the box reliably, and as shown in Japanese Utility Model Publication No. 54-37133, for example, there is a problem in that a member for this purpose, that is, a beam mounting bracket must be reattached.

しうるようにすることにある。 This idea was created by improving the above idea and focusing on securing the bolt box.The structure was created by joining a U-shaped metal fitting to the joint plate and leaving the plate connecting the upper and lower chord members protruding. The purpose is to make it simple, have superior strength, and be able to form a bolt box.

This idea forms a bolt box by joining a U-shaped metal fitting made of a curved steel plate to the back side of a joint steel plate plate that has a bolt hole approximately in the center.
The above object is achieved by welding the protruding end of the end plate of the steel plate plate that connects the tip of the U-shaped hardware and the upper chord member and lower chord member of the end portion of the reinforced steel frame made of steel plate.

る。 This segment joint fitting A is made by joining a U-shaped U-shaped metal fitting 2 made of a curved steel plate to a joint plate 1 provided with bolt holes a, and the part surrounded by the U-shaped metal fitting 2 forms a bolt box b. Then, it is joined to the reinforcing steel frame B to constitute the reinforcing steel material C of the segment.

ント継手金具Ａの接合を補強する。The segment joint fittings A are attached to the protruding plates 5 at both ends of the reinforcing steel frame B, as shown in the figure.
Welded at the tip of the At this time, anchor reinforcements 6 are welded to both sides of the U-shaped hardware 2 as shown in FIG. 2, and also to the chord members to reinforce the connection of the segment joint fittings A, if necessary.

易に、確実に行うことができる。
In this invention, since the bolt box is provided in advance on the joint fitting, the segments can be easily and reliably connected to each other.

グメント継手金具は少々の過大外力によつては変
形しにくく強度が大きい。しかもセグメントの断
面欠損も少ない。 In addition, the U-shaped metal fittings of the segment joints are formed into a U-shape by curving a steel plate.
In-plane stress (normal stress and in-plane shear stress) is generated in molded metal parts, and bending stress is difficult to generate, so segment joint fittings are difficult to deform due to slightly excessive external force and have high strength. Furthermore, there are fewer cross-sectional defects in the segments.

ムーズに伝達させることができる。 In addition, the segment joint fittings and the reinforcing steel frame are joined by welding the protruding end of the vertical plate at the end of the reinforcing steel frame and the tip of the U-shaped metal fitting, so they can be integrated into one piece with a simple joint structure. Therefore, excessive stress between the two can be transmitted reliably and smoothly.
