Description

Technical Field

[0001] The present invention belongs to the technical field of polygonal aluminum plate installation, and in particular relates to a method for installing and positioning special-shaped polygonal aluminum plates. Background Art

[0002] China's recent construction boom has seen the emergence of numerous temporary structures, particularly those built as sales offices or showrooms for real estate development. These structures are often demolished after their brief existence, partly because the land is not privately owned, leading to uncertainty and frequent demolition.

[0003] Furthermore, as consumers' living standards improve, their demands for building quality are also increasing. The contradiction between high-quality demands and outdated production methods is becoming increasingly pronounced. Consequently, traditional architectural design concepts and construction methods are no longer able to meet this demand for high-quality architecture. More and more architects are turning to splicing irregular, multi-sided panels to install on building tops, making them more representative. However, these panels are not easy to assemble, and assembling them on top of buildings further complicates both assembly and positioning. This increases the workload for builders and reduces efficiency.

[0004] Currently, most existing special-shaped and polygonal aluminum plates have problems with positioning and splicing during assembly. Summary of the Invention

[0005] In view of this, the present invention provides a method for installing and positioning special-shaped polygonal aluminum plates, aiming to solve the problem of difficulty in positioning and splicing existing special-shaped polygonal aluminum plates during assembly.
