Description

TECHNICAL FIELD

[0002] The assembly seamless aluminum plate curtain wall is a kind of modern building envelope system, which is formed by directly and closely assembling the aluminum plate unit precast in the factory to the building keel through special attachment frame assembly on site.

[0003] In the prior art, in order to ensure that the aluminum plate curtain wall realizes seamless assembly, the aluminum plates in a specific installation area are usually numbered and sequentially constructed, the first aluminum plate in the area is first bolted to the corresponding position on the keel through eight aluminum corner codes evenly distributed on four sides, then the aluminum corner codes arranged in a staggered manner on the corresponding frame of the subsequent adjacent aluminum plate are inserted into the back side of the first aluminum plate to form a concealed connection, and the remaining corner codes on the aluminum plate that are not hidden are bolted to provide restraint force.

[0004] However, the traditional method of sequentially assembling and hiding the corner codes of the tightly assembled aluminum plates has the following problems: 1. In the prior art, in order to achieve the seamless and tightly assembled effect of the aluminum plate curtain wall, the first aluminum plate must be positioned, and the sequential concealed connection of the adjacent aluminum plates is achieved by staggered insertion.
