Description

Technical Field

[0001] The utility model relates to the technical field of stone curtain walls, in particular to a dry-hanging stone curtain wall which is easy to maintain. Background Art

[0002] Stone dry hanging curtain wall is a creative form of connecting a large piece of stone shape by hanging stones on the keel attached to the building structure. The stone is mostly natural stone, which has a strong texture, natural, rich and beautiful colors, good air permeability, no alkali return, and high construction efficiency, and has been widely recognized by the construction industry. Among them, the back bolt stone curtain wall is widely used due to its good wind resistance and superior earthquake resistance. However, there are still some problems in the use of existing stone dry hanging curtain walls:

[0003] 1. Poor overall firmness. During the construction and use of existing stone dry-hanging curtain walls, the overall load-bearing capacity mostly relies on a simple fixed keel frame fixed to the wall for stress, while the heavier stone hung on it is completely suspended in the air and vertical to the galvanized steel plate. Such a stress-bearing method will cause the connection of the keel frame to loosen after long-term use, and the stone will be at risk of falling off.

[0004] 2. Poor adjustability. During the installation process of the existing stone curtain wall, it is impossible to effectively adjust and install it on uneven walls or slightly inclined walls. It can only be installed on vertical and flat walls. This installation method will greatly reduce the overall installation range. Utility Model Content
