Description

Technical Field

[0001] This utility model relates to a prefabricated dovetail tenon interlocking multifunctional wall panel, belonging to the field of prefabricated building technology. Background Technology

[0002] With the acceleration of industrialization in the construction industry, prefabricated buildings have become the mainstream development direction due to their advantages such as high construction efficiency and environmental protection and energy saving. As a key component for internal partitioning of buildings, the lightweight, modular, and rapid installation characteristics of non-load-bearing partition walls directly affect the overall construction efficiency and cost.

[0003] Existing prefabricated non-load-bearing partition walls typically employ panel systems, such as autoclaved aerated concrete (ALC) lightweight panels and gypsum lightweight panels. Additionally, some areas incorporate high-precision masonry blocks, primarily constructed using dry methods and requiring no leveling or plastering, into the prefabricated partition wall system. However, existing prefabricated non-load-bearing partition walls have the following shortcomings:

[0004] (1) The existing panel wall has vertical through joints between the panels, which poses a risk of cracking at the through joint locations during actual engineering use;

[0005] (2) When the wall has high requirements for sound insulation and heat preservation, the strip panel usually adopts a double-layer system. The cavity in the middle is filled with heat preservation and sound insulation materials such as rock wool, while the walls on both sides are separated by the filling material without any tie measures, which poses a hidden danger to the overall stability of the wall structure. In addition, the individual components of the strip panel are large in size, usually up to 3m high, and the self-weight of the individual components is large, resulting in high transportation and installation costs. Moreover, the construction is easily restricted by site and road conditions.

[0006] (3) The existing dry connection (such as bolts and clips) between the precast wall panels and the main structure has the hidden dangers of loose nodes and poor seismic adaptability, resulting in poor connection reliability.

[0007] Therefore, there is an urgent need for a non-load-bearing partition board that combines lightweight, quick installation, high durability, and functions such as sound insulation and heat preservation. Utility Model Content
