The floor slab is precast in the precast concrete component factory under ideal conditions, and contains the stiff reinforcement (truss) that is required to give stiffness once installed, as well as the flexural tension reinforcement, lengthways and crossways, that is required for assembly and the final state. The floor slab is made into a solid and monolithic reinforced concrete floor by using mix-in-situ concrete that is poured at the construction site.
The thickness of the finished floor slab is between 120 and 300 mm, depending on the span and the loading. The protruding truss reinforcement and the concrete surface itself provide the required anchoring, ensuring good bonding and adhesion between the finished part and the mix-in-situ concrete.
Advantages of Filigree Slabs
Economical: Efficient use of the Filigree method reduces cost of concrete structures.
Reduces Labor: The prefabrication technology in Filigree reduces the need for field skilled and unskilled trades. Although all trades are represented, fewer are needed for each task with a reduction in payroll needs and enhanced cash flow.
Saves Time: High production rates hence structures go up fast.
Eliminates Field Forming and Reduces Shoring Requirements.
Easy to Use: All Work is done in a traditional manner, familiar to all trades.
Reduces the Volatility and Uncertainty of Construction Cost: Filigree method of construction is less dependent on field labor and field labor productivity. It will substantially reduce the overall labor/material cost ratio.
Quality is Superior: The final product is a combination of the most desirable properties inherent to pour in place and precast construction, In addition, Filigree slabs are cast in polished steel molds, and will greatly enhance the appearance of any concrete structure.
Resists Sound Transmission: Certified reports confirm that Filigree can meet the strictest requirements of sound resistance for residential and institutional use.
Structures are Fire-Rated: The system has fire resistance ratings up to 4 hours established through a full scale fire resistance test at the Underwriter Laboratories.
Environmentally Friendly: Many trees are saved by the elimination of wood and plywood framing.
The design complies with current ACI and IBC Building Codes.
Filigree is reviewed annually by the International Code Council (ICC) for compliance with the current ACI & IBC Building Codes.
