[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0037] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] To address the shortcomings of existing stainless steel or galvanized steel plate cover structures used in building expansion joints, such as high construction difficulty, difficult maintenance, insufficient waterproofing design, easy aging of sealing materials leading to leakage, poor adaptability, susceptibility to cracking, and unsatisfactory aesthetics, the following solutions are needed: reduce conflicts with the main building structure to avoid rigid fixing that could affect the overall structural integrity; reduce the joints between the metal cover plate and the main structure to avoid the impact of future deformation on the metal cover plate and cause leakage.

[0039] In order to address the aforementioned shortcomings, such as Figure 2 and Figure 5 As shown, an integrated building wall expansion joint structure is provided. The core solution of this expansion joint structure is to use an aluminum alloy metal plate combined with an integrated waterproof sealing design (the metal plate is integrally formed + water guide groove), which can effectively solve the problems of easy corrosion, poor waterproofing and insufficient deformation adaptability of the traditional metal cover plate.

[0040] Specifically, the integrated building wall expansion joint structure mainly includes a waterproof cover plate 300 fixed at the expansion joint between the first building wall 100 and the second building wall 200 using a curtain wall steel hanging method. The waterproof cover plate 300 is made of a single piece of metal, which reduces the risk of joint leakage and improves long-term waterproof reliability. A drip line 301 is provided along the length of the waterproof cover plate 300 at its lower corner.

[0041] As a preferred option, the waterproof cover 300 is made of stainless steel or aluminum alloy, with aluminum alloy being the preferred choice. This allows for a lightweight design, reducing material consumption and lowering transportation and installation costs. Furthermore, aluminum alloy is recyclable, meeting green building requirements and offering good economic and environmental benefits. In addition, the surface of the waterproof cover 300 can be coated with paint or anodized to meet the needs of different building facade styles. This ensures a smooth transition between the waterproof cover 300 and the building facade, resulting in a simple and aesthetically pleasing design that enhances the overall visual appeal.

[0042] A water-guiding channel 302 is installed at the top outer end of the waterproof cover 300 and arranged along its length. Together with the drip line 301 at the lower end, it enables self-drainage and effectively prevents rainwater infiltration. Rainwater drips through the drip line 301 under gravity onto the inner side of the first enclosure wall 201. To facilitate rainwater discharge, a drainage wave is provided on the inner side of the first enclosure wall 201, discharging the water through corresponding drainage outlets. The integrated waterproof structure design of the waterproof cover 300 effectively reduces the risk of joint leakage and improves long-term waterproof reliability.

[0043] It is worth noting that, such as Figure 2 and Figure 5 As shown, based on the core design concept of the integrated building wall expansion joint structure, this integrated building wall expansion joint structure is applied to different wall structures and expansion joint locations, and different shapes of waterproof cover plates 300 are used in a targeted manner.

[0044] For the first building wall 100 and the second building wall 200 with a vertical layout, the following is adopted: Figure 3 The Z-shaped waterproof cover plate 300 shown is suitable for buildings with a waistline wall; and for the first building wall 100 and the second building wall 200 with a left-right layout, the following is adopted. Figure 5 The waterproof cover plate 300 with an inverted U-shaped structure shown is suitable for buildings with double-walled structures. Specifically, the expansion joint structures for the two application scenarios described above will be elaborated on through specific application examples.

[0045] Application Example 1

[0046] like Figure 2 As shown, for a building scenario with a waistline wall, a waistline wall 101 protruding outward is horizontally provided on the outer wall of the first building wall 100, and a decorative panel 102 is provided on the outer wall above the waistline wall 101. A first enclosure wall 201 is provided on the outer side of the second building wall 200, and the gap between the top of the first enclosure wall 201 and the waistline wall 101 constitutes a deformation joint.

[0047] like Figure 2 , Figure 3 and Figure 4As shown, an integrated building wall expansion joint structure is provided. This expansion joint structure mainly includes a waterproof cover plate 300 fixedly installed at the expansion joint between the first building wall 100 and the second building wall 200 using a curtain wall steel hanging method. The waterproof cover plate 300 is integrally processed from a metal plate, and a drip line 301 is provided along its length at the lower corner of the waterproof cover plate 300. The waterproof cover plate 300 is made of stainless steel or aluminum alloy, and its surface is coated with paint. Specifically, a water guide groove 302 is provided along its length at the top outer end of the waterproof cover plate 300.

[0048] like Figure 2 As shown, to achieve stable installation of the waterproof cover plate 300, the upper end of the first end 310 of the waterproof cover plate 300 is fixed to the inner side wall of the lower end of the decorative panel 102 using a curtain wall steel hanger method, with the decorative panel 102 serving as the load-bearing installation point for the waterproof cover plate 300. Furthermore, the corner of the lower end of the first end 310 is fitted into the inner corner of the bottom of the decorative panel 102 in an L-shape to reduce the joint between the waterproof cover plate 300 and the main structure, thus avoiding leakage caused by subsequent deformation of the metal cover plate.

[0049] The aforementioned curtain wall steel hanging installation method is a construction method that fixes decorative materials to the building structure using metal hangers, commonly used in stone, ceramic, and other curtain wall projects. This is a known existing construction method. For example, the upper ends of the decorative panel 102 and the first end 310 are suspended from the exterior wall of the first building wall 100 using metal parts 103 and expansion bolts. The first end 310 is concealed behind the decorative panel 102, thus achieving a certain aesthetic appeal. The first end 310 is fixedly installed on the exterior wall of the first building wall 100 using metal parts 103, ensuring the stability of the waterproof cover plate 300 installation.

[0050] As one of the preferred embodiments, such as Figure 2 and Figure 3 As shown, the waterproof cover 300 is Z-shaped, with the top end designated as the first end 310 and the bottom end as the second end 320. The first end 310 is installed on the decorative panel 102 using a curtain wall steel hanger, while the second end 320 is movably positioned on the outer side wall of the first enclosure 201. This overall installation structure avoids rigid fixing and accommodates large deformations. Furthermore, the waterproof cover 300 can be modularly designed according to the actual wall conditions, prefabricated in the factory, and assembled on-site, resulting in convenient and precise construction, reduced construction errors, and easy maintenance and replacement later.

[0051] Specifically, in order to further improve the stability of the waterproof cover plate 300 installed on the decorative panel 102, a Z-shaped fixing plate 311 connected to the metal part 103 is integrally provided on the inner side of the top of the first end 310, and a support plate 321 abutting against the first wall 201 is integrally provided on the inner side of the bottom of the second end 320.

[0052] The Z-shaped fixing plate 311 and the support plate 321 are integrally formed with the waterproof cover plate 300. The lower end of the Z-shaped fixing plate 311 is provided with a square hole for screws to be inserted to connect the decorative plate 102. The design of the square hole allows the waterproof cover plate 300 to have a certain adjustment redundancy in the vertical direction, which can adapt to large deformation of the wall.

[0053] like Figure 3 and Figure 4 As shown, based on the installation and fixation of the first end 310 at the upper end, the second end 320 of the waterproof cover plate 300 extends downward through the outer side of the waistline wall 101 and overlaps the inner side of the first enclosure wall 201. A drip line 301 is provided at the corner of its lower end to achieve self-drainage and effectively prevent rainwater infiltration. Rainwater drips onto the inner side of the first enclosure wall 201 under the action of gravity through the drip line 301. To achieve rainwater discharge, a drainage wave is provided on the inner side of the first enclosure wall 201, and the rainwater is discharged through the corresponding drainage outlet.

[0054] like Figure 2 , Figure 3 and Figure 4 As shown, the waterproof cover 300, applicable to a wall structure with a waistline, is Z-shaped, with the top end being the first end 310 and the bottom end being the second end 320. The first end 310 is connected to the metal part 103 via a Z-shaped fixing plate 311 and is suspended from the inner wall of the decorative panel 102. The second end 320 overlaps the inner side of the first wall 201 and has a drip line 301 at the bottom.

[0055] Furthermore, to minimize the gaps between the waterproof cover 300 and the decorative panel 102, the corner of the lower end of the first end 310 is fitted with the decorative panel 102 in an L-shape, so that the waterproof cover 300 and the decorative panel 102 of the building facade are smoothly connected, with a simple and beautiful shape, which can significantly improve the overall visual effect.

[0056] The installation process of the integrated building wall expansion joint structure in the scenario of a wall with a waistline is as follows: First, a waterproof cover plate 300 with a water guide groove 302 and a drip line 301 is prefabricated in the factory; second, the metal part 103 is fixed to the inner side wall of the lower end of the decorative panel 102 with expansion bolts; then, the Z-shaped fixing plate 311 of the first end 310 of the waterproof cover plate 300 is hung on the metal part 103; finally, the position of the waterproof cover plate 300 is adjusted so that the second end 320 is tightly attached to the inner side of the first wall 201.

[0057] Application Example 2

[0058] like Figure 5As shown, in a building scenario with a double-wall structure, the first building wall 100 and the second building wall 200 are arranged with a left-right gap, and a second wall 104 is provided on the outside of the first building wall 100. The second wall 104 and the first wall 201 on the second building wall 200 are arranged with a left-right gap, and a wall eave 105 is provided horizontally on the top of the second wall 104. One end of the wall eave 105 is located above the first wall 201, and the gap between it and the first wall 201 below it forms an expansion joint.

[0059] like Figure 5 As shown, the waterproof cover 300 has a U-shaped structure. Its first end 310 and second end 320 are integrally inverted and mounted on the second wall 104 and the first wall 201, completely covering the eaves 105 and expansion joints. Depending on the needs, the first end 310 or the second end 320 can be installed on the outer wall of the second wall 104 or the first wall 201 using a curtain wall steel hanger. The other end uses a non-rigid connection to accommodate large deformations.

[0060] Specifically, to achieve waterproofing and drainage, the lower left and right ends of the waterproof cover plate 300 are bent inwards, so that the inner ends of the bends abut against the corresponding second wall 104 and first wall 201 to completely cover the expansion joint. Drip lines 301 can be installed at the bends as needed to achieve self-drainage and effectively prevent rainwater infiltration. Rainwater drips through the drip lines 301 under gravity onto the inner side of the first wall 201. To facilitate rainwater discharge, drainage waves are installed on the inner side of the first wall 201, and the water is discharged through corresponding drainage outlets.

[0061] like Figure 5 As shown, this integrated building wall expansion joint structure, suitable for double-walled buildings, features a U-shaped waterproof cover plate 300 that overturns and covers the expansion joint at the top of the second wall 104 and the first wall 201. The lower left and right ends of the waterproof cover plate 300 are bent inwards to abut against the walls, with drip lines 301 installed at the bends. Rainwater from the top of the eaves 105 is diverted to both sides through the water guide groove 302 on the top surface of the cover plate, and backflow is prevented by the drip lines 301, achieving a dynamic waterproof design.

[0062] The installation process of this integrated building wall expansion joint structure in a double-wall structure scenario is as follows: First, a U-shaped waterproof cover plate 300 with a drip line 301 is prefabricated in the factory; second, the waterproof cover plate 300 is inverted and placed on the top of the second wall 104 and the first wall 201, completely covering the expansion joint; then, the first end 310 is fixed to the corresponding outer wall of the second wall 104 using metal parts 103 and expansion bolts; finally, the position of the waterproof cover plate 300 is adjusted so that the second end 320 is tightly attached to the inner side of the first wall 201.

[0063] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
