Embodiment 1
[0038] Such as Figure 1-2 As shown, a seamless expansion joint structure according to the present invention includes expansion joints 2 between two adjacent beam bodies 1, preferably, the width of the expansion joints 2 is 40mm-240mm, and each of the The beam body 1 is provided with a pavement layer 11, and a reserved notch is provided between two adjacent pavement layers 11, and also includes a cover plate 3 arranged on the expansion joint 2, and the cover plate 3 A telescopic member is arranged above, and the telescopic direction of the telescopic member is along the longitudinal direction of the bridge. The elastic-plastic body 4 is filled in the reserved slot, and the top surface of the elastic-plastic body 4 is flush with the top surface of the pavement layer 11. Flat, the elastic-plastic body 4 is a TST structural member, and the TST structural member is a member formed by a mixture of binder and aggregate. Preferably, the size of the telescopic member is adapted to the...
Embodiment 2
[0047] Such as Figure 4 As shown, a seamless expansion joint structure according to the present invention, its structure is roughly the same as that of Embodiment 1, the difference is that all the corrugated plates 6 can be replaced by steel corrugated pipes 7, each The cross-sectional shape of bellows 7 can be circular, elliptical and such as this Figure 4 The approximate elliptical cross-sectional shape, the setting direction of the bellows 7 can be as Figure 4 As shown, that is, the pipe wall of each bellows 7 is connected to the partition 5 or connected to the wall of the adjacent bellows 7 through a connecting piece, and the hollow pipe body is stretched or compressed to deform by pulling and pressing; Certainly, the axial direction of the bellows 7 can also be set along the longitudinal bridge direction, that is, the two ends of each section of the bellows 7 are connected to the two adjacent partitions 5 respectively, and each partition 5 is still provided with The ...
