Description

Technical Field

[0001] This utility model relates to the field of expansion joint repair structure technology, and in particular to a repair structure for expansion joints in an integrated panel of building facade. Background Technology

[0002] Building facades are directly exposed to the external environment and are subject to thermal expansion and contraction due to seasonal changes or diurnal temperature variations. Expansion joints provide expansion space for building facades, preventing wall cracking, peeling, or damage to the finish caused by temperature stress. Therefore, they are widely used in building facades.

[0003] After prolonged use, building facades and expansion joints often experience detachment or damage to their finishes, requiring repair and renovation. While some existing technologies exist for repairing building facade expansion joints, most only allow deformation in one direction. This results in poor performance when expansion joints exist between two vertical walls, and their integration with the integrated exterior facade panels is limited, affecting the aesthetic appeal of the building facade. For example, Chinese utility model patent application number CN201720142854.2, entitled "A Construction Structure for Building Exterior Wall Expansion Joints," uses a first fixing block, a second fixing block, and expansion screws to firmly fix the main structure within the expansion joint, preventing detachment. The combined use of these structures enhances the load-bearing capacity of the sealing panel without affecting its decorative quality. However, it only allows deformation in one direction and has limited integration with the integrated exterior facade panels. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a repair structure for the expansion joint of the building facade integrated panel. It has deformation space in both horizontal and vertical directions, which can meet the use of expansion joint between two vertical walls. Moreover, it has a higher degree of compatibility with the building facade integrated decorative panel, resulting in a better overall decorative effect of the building facade.

[0005] This utility model is achieved using the following technical solution: a repair structure for the expansion joint of an integrated panel on a building facade, comprising a first wall and a second wall, wherein the first wall and the second wall are perpendicular to each other and an expansion joint is provided between them; a first aluminum cover plate is provided on the outer side of the first wall next to the expansion joint, and a second aluminum cover plate is provided on the outer side of the second wall next to the expansion joint; the inner end of the first aluminum cover plate is Z-shaped and the outer end is annular; the inner end of the second aluminum cover plate is horizontal and the outer end is also annular; the outer ends of the first aluminum cover plate and the outer ends of the second aluminum cover plate are alternately arranged; the inner end of the first aluminum cover plate is fixed to the outer side of the first wall with cement nails, and a cover plate connecting plate is fixed to the inner end of the second aluminum cover plate; the cover plate connecting plate is fixed to the outer side of the second wall with cement nails.

[0006] Furthermore, both the first wall and the second wall are provided with a layer of thermal insulation mortar on their outer sides, and an integrated panel assembly is fixed to the outer side of the thermal insulation mortar layer.

[0007] Furthermore, the integrated panel assembly includes an insulation layer, an integrated exterior panel, an integrated panel connecting frame, connecting bolts, and expansion bolts. Several expansion bolts are spaced apart on the first wall and the second wall. The outer ends of the expansion bolts are fixed to the inner side of the integrated panel connecting frame by nuts. The outer side of the integrated panel connecting frame is connected and fixed to the integrated exterior panel by connecting bolts, so that the integrated exterior panel is horizontally set outside the first wall and the second wall. The insulation layer is filled between the integrated exterior panel and the insulation mortar layer.

[0008] Furthermore, the expansion joint is filled with a fireproof and heat-insulating layer, and a water-blocking strip is provided on the outside of the fireproof and heat-insulating layer. The two ends of the water-blocking strip are fixed to the first aluminum cover plate and the cover plate connecting plate by limiting screws.

[0009] Furthermore, a padding layer is also provided on the outside of the aforementioned thermal insulation mortar layer.

[0010] Furthermore, foamed polyurethane sealant is provided at the contact points between the end of the integrated panel assembly and the first aluminum cover plate and the second aluminum cover plate.

[0011] Furthermore, the outer end of the connecting bolt is set in a countersunk hole in the integrated exterior facade panel, and a repair cover is also fixed in the countersunk hole, with the outer end of the repair cover being horizontal to the outer surface of the integrated exterior facade panel.

[0012] Compared to existing technologies, the advantages of this utility model are as follows: The repair structure for the expansion joint area of ​​an integrated panel on a building facade of this utility model features a first aluminum cover plate on the outer side of the first wall and a second aluminum cover plate on the outer side of the second wall, both with annular outer ends and arranged in an alternating, spaced configuration. This allows for deformation space between the two aluminum cover plates in both horizontal and vertical directions, enabling them to move and thus meeting the requirements for expansion joints between two vertical walls. The integrated design of the expansion joint cover plate and the integrated panel assembly enhances the fit between the expansion joint structure and the integrated panel assembly on the building facade, thereby improving the overall decorative effect of the building facade and making it more aesthetically pleasing.
