Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, specifically relates to curtain walls, and in particular to a fastening assembly for splicing GRG modules and a GRG decoration system. Background Art

[0002] GRG modules are used in irregular shapes. Traditional GRG module construction involves welding steel frames on-site. This results in relatively low positioning accuracy during welding, leading to overall dimensional deviations. Furthermore, due to their limited size, they are difficult to transport and install. Furthermore, the need for partial rework of the steel frame base can impact construction progress and increase costs.

[0003] Furthermore, after installing the surface GRG modules, the panels are limited by the adjustable dimensions of the mounting brackets, making full angle adjustment difficult. This can lead to misalignment, gapping, and height differences. Improperly polished joints can result in noticeable ridges, and poorly polished joints can magnify surface imperfections under lighting, affecting the visual experience. Furthermore, over time, improperly treated joints between GRG modules can lead to cracking and deformation.

[0004] Therefore, there is an urgent need to develop a new fastening assembly for GRG module splicing and a GRG decoration system to solve the technical problem of how to overcome the surface cracking caused by the misalignment and loose deformation between GRG panels.

[0005] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.
