Embodiment 1
[0021] Such as figure 1 (Schematic diagram of the structure of the multi-directional displacement composite plate telescopic device), the device is mainly composed of a displacement device 1 and a fixed plate 2, and the fixed plate 2 is welded to the inner side beam 7 of the displacement device 1 by welding. One end of the fixed plate 2 is welded flush with the upper surface of the inner side beam 7 of the displacement device to form an integral structure, the inner side is formed by a supporting block 6 as a force transmission fulcrum, and the PTFE plate on the upper surface of the supporting block 6 and the fixed plate 2 form a sliding support point. The other side of the fixed plate 2 is connected to the bridge deck through the bolts on the anchor assembly. The anchor assembly is composed of the anchor box 3, the compression rubber block 4 and the connecting bolt 5. The fixed plate 2 is embedded in the anchor box 3 through the boss at the bottom. The bottom of the boss and ...
