Prefabricated Floor Slab and Steel Beam House

Prefabricated floor slabs can be applied in steel beam houses.

Specific Application Systems

• Earthquake-Resilient Rapid-Assembly Multi-Story Prefabricated Steel Structure System: In this system, the floor slabs use steel-ribbed prestressed concrete composite slabs, which are used in conjunction with a steel frame-bracing structural system. The steel-ribbed prestressed concrete composite slabs combine the properties of steel and concrete. The steel ribs provide a certain degree of strength and stiffness support, while the prestressed concrete part ensures the basic load-bearing capacity of the floor slabs. The two work together to meet the usage requirements of multi-story steel structure houses for floor slabs.
• Fully Prefabricated Demountable Hidden-Frame Panel Villa System: This system adopts a hidden steel frame panel structure. The floor slabs use fully prefabricated concrete floor slabs, and the joints are connected with bolts. The fully prefabricated concrete floor slabs are manufactured in advance in the factory, with standardized dimensions and specifications. They are reliably combined with the hidden steel frame through bolt connections, enabling the quick and convenient construction of the villa's floor structure.

Advantages of Prefabricated Floor Slab Application

• Fast Construction Speed: Prefabricated floor slabs are produced centrally in the factory, unaffected by factors such as the on-site construction environment, allowing for large-scale and standardized production. Only simple hoisting and connection operations are required on the construction site, greatly shortening the construction period of the floor slabs and accelerating the overall construction progress of the house.
• Low Cost: Factory production enables centralized material procurement and optimized use, reducing waste and lowering material costs. At the same time, the efficient construction process reduces labor input and construction time, resulting in relatively low overall costs.
• Relatively Stable Quality: Under the strict production environment and quality control system in the factory, quality indicators such as the dimensional accuracy and concrete strength of the prefabricated floor slabs can be better guaranteed, reducing quality fluctuations caused by differences in on-site construction conditions.

Application Precautions

• Poor Integrity: The connections between prefabricated floor slabs and between them and steel beams are relatively weak. When subjected to large external forces, problems such as damage to the connection parts are likely to occur, affecting the overall performance of the structure.
• Limited Seismic Performance: Due to limitations in integrity and connection methods, the seismic capacity of prefabricated floor slabs is inferior to that of cast-in-place floor slabs under earthquake action. Therefore, they are more suitable for non-seismic areas or low-rise buildings, where the earthquake action is relatively small, and the impact of the seismic performance defects of prefabricated floor slabs on structural safety is relatively minor.
