Reinforced Concrete Prefabricated Components
Common types of reinforced concrete prefabricated components include prefabricated reinforced concrete truss floor panels, prestressed reinforced concrete circular hole slabs, and prefabricated components for steel-structured villas. The following is a detailed introduction:
Prefabricated reinforced concrete truss floor panels (with non-removable bottom formwork): In this system, the reinforcement in the floor slab is processed into a truss in the factory and prefabricated together with the fine aggregate concrete bottom slab to form a reinforced concrete truss floor panel with a non-removable bottom formwork. During construction, the floor panel is directly laid on the beam surface system, and necessary connecting structural reinforcement is arranged on-site, followed by concrete pouring to form a complete reinforced concrete floor slab system. Its advantages are significant. The reinforced concrete truss floor panel can bear the load during the construction of the wet concrete material. After the floor slab is formed, the concrete bottom formwork is not removed and can serve as an integral part of the floor slab structure, working in conjunction with the cast-in-place concrete to enhance the overall integrity and stability of the structure. At the same time, this system has the advantages of simple structure, convenient construction, excellent quality, and superior load-bearing performance. It is also easy to standardize production, complies with the concept of green and low-carbon development, has good economic performance, and can effectively reduce construction costs and duration.
Prestressed reinforced concrete circular hole slabs: These are standardized building components designed according to the 'Code for Design of Concrete Structures' GB50010-2010, using prestressed technology to enhance structural performance. These components are mainly used in rural residential buildings. The national standard atlas 'Prestressed Concrete Hollow Slabs (EHC Slabs)' released in 2025 has further expanded their application scope to large-span public buildings, industrial plants, and logistics warehouses. Through standardized production, prestressed reinforced concrete circular hole slabs achieve serialized configurations of span and load, meeting the needs of different building scenarios and improving the versatility and flexibility of buildings.
Prefabricated components for steel-structured villas: Steel-structured villas adopt an assembled construction method. For example, the prefabricated thermal insulation walls on the first floor are produced on a factory assembly line, providing excellent thermal insulation and fire resistance, effectively improving living comfort and safety. During floor construction, the floor profiled steel sheets are first installed and the steel reinforcement mesh is bound, followed by concrete pouring for the floor slab. This construction method improves construction efficiency and ensures construction quality.
