Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of laminated slab, specifically is a fabricated laminated slab. BACKGROUND

[0002] In the field of traditional fabricated house construction, the design and application of laminated slab generally have certain limitations. Specifically, the traditional laminated slab usually only uses a single material or only uses a simple composite structure design. Based on in-depth analysis of existing technology, we found that in the traditional fabricated house construction, the design of laminated slab is often relatively simple and single. This design method is prone to local deformation in areas with large building stress, such as floor slabs, walls, and other key parts, which can affect the stability and safety of the entire structure. Due to the limited carrying capacity of single material or simple composite structure, these areas may face greater safety hazards during long-term use; in addition, the materials used in traditional laminated slab are often thick and heavy, which not only results in a large weight of the laminated slab, increasing the overall weight of the building. At the same time, in order to achieve waterproof, heat insulation, sound insulation and other performances, additional materials or structures are often needed. This not only increases the complexity and cost of the building, but also may affect the aesthetics of the building.

[0003] Therefore, in order to overcome the above shortcomings of traditional laminated slab, it is necessary to improve and optimize it to improve the performance of fabricated house construction, reduce cost, improve construction efficiency, and realize functional integration.
