In bottom longitudinal ripple section 110 longitudinal wave arc section 111 opening direction towards inner side, in most interior
The opening direction of the lateral wave arc section 311 of the transverse wave section 310 of side is downward.The structure makes the longitudinal direction in bottom
Bellows segment 110 can preferably support other longitudinal ripple sections 110, and the transverse wave section 310 in most inner side can be more preferable
The other transverse wave sections 310 of ground support.
Connecting portion 200 is to be obliquely installed relative to transverse direction；Connecting portion 200 includes the first linkage section 210, mistake being sequentially connected
The linkage section 230 of segmental arc 220 and second is crossed, the first linkage section 210 is connected with the longitudinal ripple section 110 in bottom, and second connects
Connect section 230 to be connected with the transverse wave section 310 in most inner side, the first linkage section 210 and the second linkage section 230 are both with respect to horizontal stroke
To be obliquely installed.
Connecting portion 200 is relative to laterally to be obliquely installed, the structure can make longitudinal ripple portion 100 and transverse wave portion
Connection transition between 300 is more smooth, has both avoided the stress concentration of junction, while machine-shaping is easier to realize.Meanwhile,
So that the structure of connecting portion 200 is corresponding to the structure of longitudinal ripple section 110 and transverse wave section 310 so that longitudinal ripple portion 100
And connection transition between transverse wave portion 300 is more smooth.
The opening direction of transition segmental arc 220 makes the company between longitudinal ripple portion 100 and transverse wave portion 300 towards outside
Take over and cross smoother.
First linkage section 210 is tangent with transition segmental arc 220, and the second linkage section 230 is tangent with transition segmental arc 220.The structure
So that connecting portion 200 forms U-shaped structure, the first linkage section 210 and the second linkage section 230 constitute smoothed with transition segmental arc 220
The combining form crossed, it is ensured that the reliability of feasibility and expansion joint the body connection of processing.
To ensure expansion joint body, when two direction displacement of vertical and horizontal is absorbed, will not be lost because of strength problem
