This technology is a fire-resistant composite floor panel featuring upper and lower plates facing each other with a rim to create a filling space. Inside, a wire-mesh fire-resistant holding reinforcement is fixed to the plates, and the space is filled with fire-resistant synthetic resin. As the resin penetrates the mesh and hardens around its free ends, the plates and the filler are integrated into a single unit.
Traditional floor construction relies on wet methods involving formwork, concrete pouring, and curing, which require temporary works, long curing times, and complex on-site labor. These processes also incur high costs and CO2 emissions from concrete production and waste disposal. While sandwich panels are common for non-structural partitions, metal-reinforced versions often fail as fire-rated flooring because the internal resin can vaporize, melt, or delaminate from the metal at high temperatures.
This technology connects a first wire mesh to the lower plate and cross-welds a second wire mesh vertically to form a 3D grid. The lower plate surface is textured with aggregates, folded plates, or embossed patterns to enhance adhesion to the resin. Optionally, stud bolt shear connectors with wide heads can be used to meet specific design requirements. Suitable for dry floor slabs in steel buildings, modular home floor panels, and prefabricated structural panels, it slows deflection during fires without concrete pouring, achieving the standard 2-hour fire resistance rating.
