Description

TECHNICAL FIELD

[0001] The utility model relates to building decoration material technical field especially is related to a waterproof fixing structure of upper and lower wallboard plug interface. BACKGROUND

[0002] In the field of external wall decoration, with the development of modern building technology, various new building materials and construction methods have emerged, greatly improving the appearance and durability of buildings. Especially the application of external wall panels not only beautifies the appearance of the building, but also effectively protects the main body of the building from the influence of the external environment. However, in the actual application process, the connection joint treatment of the external wall panel has always been one of the problems plaguing the field.

[0003] At present, in order to ensure the tight connection between the external wall panels and have good waterproof performance, the industry generally uses the method of injecting glue to handle the connection joint. Specifically, the common practice is to inject sealant between two wall panels to fill the gap and form a waterproof barrier. In addition, some projects will choose to use rubber strips or other elastic materials to fill the gap to further enhance the waterproof effect.

[0004] The above method is prone to the problem of insufficient glue injection or sealant failure in actual application, which allows rainwater to easily enter the connection joint between the two adjacent wall panels, thereby causing water seepage. This not only affects the overall appearance of the building, but also poses a potential threat to the safety and durability of the building structure. Therefore, a more reliable and durable waterproof fixing structure is needed to solve this problem. UTILITY MODEL CONTENTS

[0030] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0031] This utility model discloses a waterproof fixing structure for the insertion interface of upper and lower wall panels, such as Figure 1 and Figure 2 As shown, the structure includes an upper wall panel 1 and a lower wall panel 2. The upper wall panel 1 is provided with an outward protrusion 3, and the lower wall panel 2 is provided with an inward concave portion 4. The outward protrusion 3 and the inward concave portion 4 are interlocked. A structural nail 5 is provided on the lower wall panel 2. The structural nail 5 penetrates the lower wall panel 2 and extends into the interior of the building wall to achieve a stable fixation. An installation groove 10 is provided on the surface of the lower wall panel 2. The structural nail 5 is installed in the installation groove 10. A fixing washer 11 is provided on the side of the structural nail 5 near the installation groove 10. The other side of the fixing washer 11 abuts against the installation groove 10. The fixing washer 11 is used to improve the stability of the fixing of the structural nail 5.

[0032] The outer convex part 3 of the upper wallboard 1 is provided with a partial wallboard on both sides, which is used to block the structural nails 5 and prevent water from seeping into the structural nails 5 to corrode them. The cavity 7 is arranged between the structural nails 5 and the partial wallboard, which is used to prevent capillary water seepage and improve the waterproof effect. The shape of the cavity 7 is designed according to the embedding of the outer convex part 3 and the inner concave part 4, so as to ensure good drainage performance and reduce the possibility of water accumulation. The contact surfaces of the outer convex part 3 and the inner concave part 4 are provided with micro protrusions to improve the friction. The micro protrusions can be manufactured by a mold forming process, or can be formed by subsequent processing. In this way, not only the roughness of the contact surface can be increased, but also the sealing performance can be improved to a certain extent. For example, the height of the micro protrusions is between 0.1mm and 0.5mm, and the interval can be adjusted according to needs. The embedded joint of the outer convex part 3 and the inner concave part 4 is provided with a sealing edge 8 for sealing treatment. The sealing edge 8 can be made of rubber material, which has excellent elasticity and weather resistance. In addition, high molecular materials such as silicone or polyurethane can also be selected. These materials not only have good sealing performance, but also can adapt to various climate conditions. The cross-sectional shape of the sealing edge 8 can be rectangular, trapezoidal or semicircular. The specific selection should consider the sealing effect and installation convenience. The outer convex part 3 and the inner concave part 4 are both provided with chamfers 9. The chamfers 9 make the contact surfaces of the outer convex part 3 and the inner concave part 4 closely fit when embedded. The angle of the chamfer 9 is usually about 45°, which can ensure smooth assembly process and the tightness of the connection. The length of the chamfer 9 is generally within the range of 2-5mm. Too long will affect the overall strength, and too short will not achieve the expected sealing effect.

[0033] The end of the upper wallboard 1 and the lower wallboard 2 is provided with a male end sealing element 6, which is arranged at the connecting surface of the upper wallboard 1 and the lower wallboard 2, and is used to prevent rainwater from entering the connecting joint. The male end sealing element 6 can be a strip-shaped part made of flexible material, such as EPDM rubber or TPU thermoplastic polyurethane elastomer. These materials have good flexibility and resilience, and can effectively fill the connecting joint to prevent water penetration.

[0034] Working principle: The upper and lower wallboard 2 plug-in interface waterproof fixing structure designed by the utility model realizes the reliable connection between the upper and lower wallboard 2 through the mutual embedding of the outer convex part 3 and the inner concave part 4 and the stable fixation of the structural nails 5. At the same time, the water seepage into the structural nails 5 to corrode them is effectively prevented through the setting of the partial wallboard and the cavity 7. In addition, the multiple design of the micro protrusion, the sealing edge 8, the chamfer 9, the fixing gasket 11 and the male end sealing element 6 further improves the waterproof performance and durability of the whole structure. This scheme not only solves the problems existing in the traditional glue injection method, but also greatly improves the overall quality and safety of the outer wall decorative plate.

[0035] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
