Description

Technical Field

[0001] The utility model relates to the technical field of curved ceilings, in particular to a large-span multi-layer curved ceiling structure. Background Art

[0002] Large-span curved ceilings are a type of decoration design commonly used in large spaces, which can increase the three-dimensional sense and visual effect of the space. Lightweight materials such as gypsum board, aluminum alloy, fiberglass, etc. are usually used to make curved structures, and special support systems and installation methods are used to fix the ceilings. Designers and engineers need to consider the load-bearing capacity, stability and installation technology of the structure to ensure the safety and beauty of large-span curved ceilings. There are at least the following disadvantages in the use of existing curved ceilings: 1. Most of the existing curved ceiling connectors are pre-cut brackets, but the ceiling has an arc, and beams are prone to appear on the ceiling, which leads to the need for construction workers to adjust and cut the brackets on site during the installation process, affecting the convenience of installation. Therefore, we have launched a large-span multi-layer curved ceiling structure. Utility Model Content
