Description

Technical Field

[0001] The utility model relates to the sealing construction technology of the joints of exterior wall aluminum plates, and particularly relates to a sealing structure for the joints of an aluminum plate curtain wall. Background Art

[0002] After the traditional aluminum plate curtain wall construction is completed, sealant needs to be applied at the joints. The following problems will occur during the sealant application process:

[0003] 1. Sealant quality problems: There are various types of sealants on the market with uneven quality. The quality problems of the sealant will directly affect the waterproof effect of the aluminum plate curtain wall, resulting in a large amount of later maintenance.

[0004] 2. To ensure the overall effect of the exterior wall aluminum plate curtain wall, especially the treatment of the sealant joints plays a crucial role. This puts higher requirements on the professional technical ability and sense of responsibility of the sealant application workers. Otherwise, it will be labor-intensive, material-consuming, time-consuming and fail to achieve the due effect, and will also cause a large cost expenditure for the project itself.

[0005] 3. The quality guarantee period of the sealant is 25 years, and the better quality guarantee is about 30 years. The service life of the building is 50 - 70 years. After 30 years, the function of the weather-resistant sealant may fail, and it is necessary to repair and apply sealant to the exterior wall of the building again, which requires additional expenses.

The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end.

[0021] First Embodiment:

[0022] A sealing structure for the joint of an aluminum plate curtain wall, as Figure 1 shown, includes a wall body 1 of a building main body. A heat preservation layer 2 is bonded and fixedly connected to the wall body 1. An aluminum plate 3 is fitted in a clearance outside the heat preservation layer 2. There is a splicing seam between adjacent aluminum plates 3. A first splicing member is fixedly connected to one side of the splicing seam, and a second splicing member is fixedly connected to the other side of the splicing seam. The first sealing member includes a first fixing portion 6 and a first splicing portion 61. The second sealing member includes a second fixing portion 5 and a second splicing portion 51. The first fixing portion 6 and the second fixing portion 5 are respectively bonded and fixedly connected to the corresponding aluminum plates 3. The first fixing portion 6 and the second fixing portion 5 are both plates and there is a clearance between them. The second splicing portion 51 protrudes into this clearance. To improve the matching effect between the second splicing portion 51 and the first splicing portion 61, the cross-section of the side edge of the second splicing portion 51 is a hemispherical structure, and the hemispherical structure abuts against the back of the first splicing portion 61. The first splicing portion 61 is an elastic arc-shaped structure and extends towards the second splicing portion 51. Preferably, the first splicing portion 61 is an inner arc, which is convenient for the first splicing portion 61 to cooperate with the hemispherical structure. The outer edge of the first splicing portion 61 overlaps and fits with the second splicing portion 51, which can adapt to the change in the width of the splicing seam caused by the installation error of the aluminum plate 3, so that the first splicing portion 61 and the second splicing portion 51 seal this clearance, and further the first sealing member and the second sealing member seal the splicing seam. Both the first sealing member and the second sealing member are made of aluminum alloy material, so that the sealing structure has a service life similar to that of the aluminum plate 3, thus avoiding the later maintenance cost.

[0023] Among them, a first limiting plate 52 is fixedly connected to one side of the second fixing part 5 away from the second splicing part 51. The first limiting plate 52 extends towards the first fixing part 6 and approaches the first fixing part 6. A limiting platform 53 is fixedly connected to the first limiting plate 52. A second limiting plate 62 is fixedly connected to the position of the first fixing part 6 corresponding to the limiting platform 53. The second limiting plate 62 is attached to the first limiting plate 52 and abuts against the limiting platform 53, thereby limiting the minimum width of the gap, and further preventing the first splicing part 61 and the second splicing part 51 from being too close and ensuring the sealing effect between the two; the first fixing part 6, the second fixing part 5, the first splicing part 61, the second splicing part 51, the first limiting plate 52 and the second limiting plate 52 enclose a cylindrical structure; to improve the sealing effect of the splicing seam, a foam rod 7 is arranged in the cylindrical structure, and the opposite sides of the foam rod 7 respectively abut against the first fixing part 6 and the second fixing part 5.

[0024] In addition, to improve the fixing and sealing effects of the first fixing part 6 and the second fixing part 5 with the aluminum plate 3, fixing plates 9 are integrally arranged on both the first fixing part 6 and the second fixing part 5. The fixing plates 9 are attached to and fixedly connected to the back surface of the aluminum plate 3; the fixing plates 9 are fixedly connected to the aluminum plate 3 through self-tapping screws 82, and both the first fixing part 6 and the second fixing part 5 are fixedly connected to the corresponding aluminum plate 3 through rivets 81. The rivets 81 and the self-tapping screws 82 are used in combination, thereby improving the fixing effect and stability of the first seal and the second seal with the corresponding aluminum plate 3. To facilitate the fixing connection of the rivets 81 and the self-tapping screws 82 with the aluminum plate 3, a square tube 31 is fixedly connected to the side of the aluminum plate 3, and both the rivets 81 and the self-tapping screws 82 are fixedly connected to the square tube 31.

[0025] Second Embodiment:

[0026] In the case where other technical features are the same as those in the first embodiment, as Figure 2 shown, the part of the second splicing part 51 protruding into the gap is a second arc structure with elasticity, and a stepped area 4 that fits each other is arranged between the arc structure of the first splicing part 61 and the second arc structure.

[0027] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
