Description

Technical Field

[0001] The utility model relates to the technical field of building construction curtain walls, and particularly relates to a connecting structure between an arc-shaped decorative panel at the top of a building and a glass curtain wall. Background Art

[0002] With the rapid development of building structures, people have higher and higher visual requirements for the exterior decoration structures of building structures. The traditional angular plane structure can no longer meet the current aesthetic requirements. The exterior curtain wall of a building generally adopts a structural form composed of a combination of various decorative panels such as glass, metal plates, and stone. The connection of these decorative panels should not only meet the requirements of the building appearance effect, but also meet the requirements of curtain wall connection strength, sealing performance, and convenient construction. At present, the connection of the exterior finishes of curtain walls with different structural forms is mostly planar connection, resulting in a relatively single decorative effect. In addition, connecting pieces need to be added at the connection positions to improve the structural strength and sealing performance at the connection positions, which makes the structure at the connection positions bulky and reduces the smoothness of the overall structure. The utility model patent with the authorization announcement number of CN 207700463 U discloses a connection structure for vertical decorative panels of a glass curtain wall, including a connecting plate, a decorative panel, a column, and a connection skeleton. The connecting plate includes a connecting plate and support plates and fixing plates arranged at both ends of the connecting plate. The decorative panel is provided with an installation groove. The support plate is inserted into the installation groove and fixed by bolts. The column is matched with the connection skeleton. The column is provided with a boss, and the end of the fixing plate is provided with a groove matched with the boss. The fixing plate and the column are connected by matching the boss with the groove and fixed by screws. A waterproof layer mechanism is arranged between the connecting plate and the decorative panel, and between the connection skeleton and the decorative panel. Cover plates are arranged on both sides of the installation groove of the decorative panel. By adopting a connecting piece with a special structure, the decorative panel is connected to the column, which is convenient for disassembly and assembly, simple in construction operation, and has good integration. However, the manufacturing cost of this structure is high, it requires a certain installation space, and it cannot be installed and used at the corners of the structure, so the versatility is poor. Content of the Utility Model

[0003] The purpose of the utility model is to provide a connecting structure between an arc-shaped decorative panel at the top of a building and a glass curtain wall. This structure has good connection stability, sealing and waterproof ability, smooth transition between the decorative panel and the glass curtain wall, and also has good decorative effect, improving the visual effect of the building structure.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:
