Description

Technical Field

[0001] This utility model relates to the field of composite slab technology, specifically to an assembled composite slab made of cement fiber material. Background Technology

[0002] In the field of prefabricated buildings, cement-based fiber composite slabs have attracted much attention for their unique structure and performance. These slabs consist of two main parts: a precast base slab and a steel truss. Their combination provides the building structure with excellent load-bearing capacity and stability. The precast base slab, as the foundation layer of the composite slab, uses cement, straw, and other sustainable agricultural and forestry waste plant fibers, as well as functional additives and specially formulated expanded resin particles as raw materials. These materials are mixed with water and solidified in a mold to form the robust structure of the precast base slab. The steel truss constitutes the upper structure of the composite slab. It is made up of upper chord steel bars, lower chord steel bars, and side web steel bars connected by a precise welding process. This design not only enhances the overall strength and rigidity of the composite slab, but also ensures that it can safely withstand various service loads.
