Description

Technical Field

[0001] The utility model belongs to the technical field of building decoration, especially the technical field of interior building decoration, and relates to an interior wall decoration system. Background Art

[0002] Traditional building decoration wallboards still have the following deficiencies that need to be improved urgently: For traditional decoration wallboards, material processing is generally carried out on site, most of the work is wet operation, the curing period is long, and the pipeline structure is not separated and needs to be grooved twice. Traditional decoration involves multi-disciplinary cross-operation, which is prone to delays in the construction period due to untimely coordination and cooperation and quality defects. Traditional decoration materials are usually processed on site for the second time, which is extremely easy to cause waste of resources, increase costs, and affect the ecological environment. Traditional decoration is limited by the treatment of materials and the different technical levels of constructors, resulting in difficulty in ensuring the same quality every time during construction, and it is extremely easy to have problems such as hollowing, cracking, and water leakage, with a high rework rate. The spatial functional pattern of traditional decoration is rigidly defined and not easy to change.
