This achieves a reliable connection and deformation recovery between the aluminum alloy center plate and the base, improving the stability and deformation adaptability of the structure.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of expansion joint technology, specifically to an expansion joint structure. Background Technology
[0002] Expansion joints are a general term encompassing expansion joints, settlement joints, and seismic joints. Buildings often deform under external influences, leading to cracking and even damage. Expansion joints are structural joints designed to address these issues. For example, expansion joints are vertical gaps installed at appropriate locations within the building, separating the walls, floors, roof, and other structural components from the foundation upwards, dividing the building into several independent parts. Joints designed to overcome excessive temperature differences may not require continuity in the foundation, but rather extend from the top of the foundation to the roof along the structural line. Seismic joints, on the other hand, are designed to create a more regular building structure and enhance its earthquake resistance. They may also not require continuity in the foundation. Their purpose is to divide large buildings into smaller, relatively independent seismic units, preventing damage caused by inconsistent overall building vibrations during earthquakes.
[0003] Existing expansion joints mainly achieve deformation by pre-drilling holes in the aluminum alloy center plate and aluminum alloy base, with the hole diameter larger than the diameter of the bolts (such as impact bolts) fixing the aluminum alloy center plate and aluminum alloy base. This allows the aluminum alloy center plate and aluminum alloy base to be misaligned to a certain extent. However, after the intermediate structure shifts between the aluminum alloy center plate and aluminum alloy base, there is no force to drive the aluminum alloy center plate and aluminum alloy base to return to their original relative state, which is detrimental to the stability of the structure. Utility Model Content
[0004] In view of the problems existing in a current expansion joint structure, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide a deformation joint structure that solves the problem of existing deformation joints. This is mainly achieved by pre-drilling holes in the aluminum alloy center plate and aluminum alloy base, with the hole diameter larger than the diameter of the bolts (such as impact bolts) fixing the aluminum alloy center plate and aluminum alloy base. This allows for a certain degree of misalignment between the aluminum alloy center plate and aluminum alloy base, thus achieving the deformation purpose. However, after the intermediate structure shifts between the aluminum alloy center plate and aluminum alloy base, there is no force to drive them back to their original relative state, which is detrimental to the stability of the structure.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

Figure 1-4 The system includes a substrate, on which an aluminum alloy reinforcing plate 1 is disposed. A second aluminum alloy base 20 is mounted on the aluminum alloy reinforcing plate 1. A first aluminum alloy base 7 is welded onto the second aluminum alloy base 20. A deformation buffer cavity 6 is formed between the first aluminum alloy base 7 and the second aluminum alloy base 20. In the presence of the deformation buffer cavity 6, space is provided for the deformation of the first aluminum alloy base 7 and the second aluminum alloy base 20. A second sealant 4 is disposed between the top of the second aluminum alloy base 20 and the first aluminum alloy base 7. A fourth sealant 11 is disposed between the first irregularly shaped card plate 10 and the substrate.
[0028] A first irregularly shaped card plate 10 is provided on one side of the second aluminum alloy base 20. The first irregularly shaped card plate 10 is snapped with a second irregularly shaped card plate 12. An aluminum alloy center plate 8 is provided on both the first irregularly shaped card plate 10 and the first aluminum alloy base 7. A second decorative plate 9 is provided on the first aluminum alloy base 7. A third sealant 5 is provided between the second decorative plate 9 and the first aluminum alloy base 7.
[0029] The aluminum alloy reinforcing plate 1 and the second aluminum alloy base 20 are both fixed to the substrate by metal expansion anchors 21; the aluminum alloy reinforcing plate 1 is fixed to the substrate by the second plastic expansion anchor 18 and the third plastic expansion anchor 19.
[0030] The second aluminum alloy base 20 has a first decorative panel 2 on one side, and a first sealant 3 is filled between the first decorative panel 2 and the second aluminum alloy base 20.
[0031] The first irregularly shaped card plate 10 has a first insertion cavity 101 and a first protrusion 102, and the second irregularly shaped card plate 12 has a second protrusion 121 and a second insertion cavity 122.
[0032] The first protrusion 102 is inserted into the second insertion cavity 122, and the second protrusion 121 is inserted into the first insertion cavity 101.
[0033] A stainless steel slide rod 14 is installed on the second aluminum alloy base 20 by a first bolt 22. The stainless steel slide rod 14 and the aluminum alloy center plate 8 are fixed by a second bolt. A spring 17 is sleeved on the second bolt. A through hole with a diameter larger than that of the second bolt is opened on the stainless steel slide rod 14.
[0034] The second irregularly shaped plate 12 is fixed to the substrate by the first plastic expansion anchor 13; and a waterstop 15 is provided below the stainless steel slide rod 14, and a fire-resistant strip 16 is provided below the waterstop 15.

[0035] In practical use, when the second decorative panel 9 is subjected to pressure, the first aluminum alloy base 7 and the second aluminum alloy base 20 will deform. The deformation buffer cavity 6 provides space for the deformation of the first aluminum alloy base 7 and the second aluminum alloy base 20. When the second decorative panel 9 is subjected to pressure, the first irregularly shaped plate 10 sinks down, which drives the stainless steel slide rod 14 to sink down and exert pressure on the spring 17, thereby causing elastic deformation. When the second decorative panel 9 loses its force, the stainless steel slide rod 14 and the first irregularly shaped plate 10 recover their deformation under the elastic force of the spring 17.
