Among them, the inner wall of the sliding groove is an arc surface, and the inner diameter of the sliding groove is 20mm. When the surface of the main structure 3 has an exterior wall decoration layer 5, the substrate 1011 has an outer baffle 1013 on the side away from the deformation joint 2, and the height of the outer baffle 1013 is consistent with the thickness of the exterior wall decoration layer 5. Among them, the exterior wall decoration layer 5 is formed by decorative plastering or exterior wall paint. Under the above conditions, the aluminum alloy base is made of a steel plate with a thickness of 2mm, a cross-sectional length of 50mm, a width of 14mm+the thickness of the exterior wall decoration layer 5, and a vertical length depending on the length of the structural deformation joint 2.

[0025] There are multiple slide bars 102. The length direction of each slide bar 102 is set at an angle to the width direction of the deformation joint 2, and the two ends of each slide bar 102 are movably connected to the two bases 101. Specifically, the ends of the slide bars 102 have balls 1021, which are inserted into the sliding grooves. Among them, the slide bars 102 are stainless steel slide bars, and the two ends of the stainless steel slide bars are balls 1021 with a diameter of 20mm, and the length of the balls 1021 depends on the width of the deformation joint 2 between the two adjacent main structures 3. The distance between the slide bars 102 is 500mm.

[0026] The two sides of the cover plate 103 are respectively placed on the two bases 101. The cover plate 103 is arranged above each slide bar 102, and the cover plate 103 is connected to each slide bar 102. Specifically, the cover plate 103 is placed on the base plate 1011.
