配設することが知られている。(Prior art) A rubber reinforcing layer is buried between segment rings in order to allow relative displacement of segment rings facing each other due to ground movement and to prevent water, dirt, etc. from entering the rings. Alternatively, it is known to provide a flexible member made of a rubber-like elastic material.

す。An example of such a flexible joint is the one shown in FIG. 4, in which a housing 12 is attached to each end face of the opposing segment ring 10, and a flexible joint with a corrugated cross section is attached to a fixture 14 provided there. A flexible member 16 is disposed between the casings 12, and a load-bearing member 18 is disposed between the casings so as to be movable in the axial direction of the segment ring 10. The structure prevents the ring from deforming significantly inward in the radial direction. In addition, code 2
0a and 20b indicate flexible water stop members disposed radially inward and outward with respect to the flexible member 16, respectively.

工に要する工程が増大するという問題があった。(Problem to be Solved by the Invention) However, in a flexible joint having such a structure, both ends of the load-bearing member 16 are held movably in the axial direction of the segment ring relative to each housing, and the load-bearing member 16 is held movably in the axial direction of the segment ring. Since the structure is to prevent the members from being pulled out and falling, a cavity must be formed in the housing, and in addition, load-bearing members must be installed at intervals of 100 to 200 mm in the circumferential direction of the segment ring. Therefore, there was a problem that the structure became complicated and the steps required for manufacturing and construction increased.
本発明はこのような問題に鑑みてなされたものであり、

として示す。The support ribs 28 are located inward from the wave-shaped flexible member 16 and prevent undesired inward deformation of the flexible member due to dirt or the like. The supporting ribs 28 of the opposing fixtures 14 are arranged in a direction along the wall member 13b of the connecting frame so as to allow relative displacement of the segment ring 10 due to ground conditions, especially relative displacement in the axial direction. In other words, they are arranged at predetermined intervals in the circumferential direction of the segment ring. This situation is illustrated by reference numerals 28a and 28b.

。Similar to the embodiment shown in FIG. 1, the support ribs 28 protrude from the fixture 14 toward the end face of the other connecting frame 13 facing each other, and are spaced apart from each other in the circumferential direction of the segment ring. However, in this embodiment, the free end of the support rib 28 is
It shall be located on the opposing fixture 14 side. However, it is of course possible to adjust the dimensions of the support ribs 28 in the ring axis direction so as not to impede the displacement of the flexible member I6 in the segment ring axis direction. Moreover, the inclined part 30 of the support rib is
It can also be shaped to correspond to the curvature of the flexible member.
そして、この様な構成とすることにより、取付具１４の
部品点数を低減させ、更には、取付具１４の壁部材１３

４の一端をこれもボルト等を用いて固着する。One end of the support 32 is fixed to the wall member 13a of the connection frame 13 with a bolt or the like, while another attachment 3 is attached to the other end of the support 32.
Fix one end of 4 using a bolt or the like.
これに対し、他の取付具３４の一端を、連結枠１３の壁
部材１３ｂにこれもボルト等を用いて固着する。On the other hand, one end of the other fixture 34 is also fixed to the wall member 13b of the connecting frame 13 using a bolt or the like.

それゆえ、たとえ外方に位置する可撓性部材１６が破損
するような状況にあっても、当該可撓性部材３６により
土砂等の侵入が阻止されることになる。Therefore, even if the flexible member 16 located on the outside is damaged, the flexible member 36 will prevent dirt and sand from entering.

Therefore, compared to conventional support structures, the structure of the support member that supports the connecting frame and the flexible member can be made extremely simple, and it can be easily attached to the segment ring. In addition, since there is no need to support the support member so that it can move freely relative to the casing, the dimensions of the support structure do not increase significantly even if the structure has multiple layers of flexible members. It has the advantages of
