What is a Steel Formwork For Box Girders?

Steel Formwork For Box Girders and T-Beams is a specialized reusable bridge formwork system designed for precast and cast-in-situ construction of large-span bridge structures. It is widely used in highways, railways, and municipal bridge projects. The system is engineered to ensure precise geometric shaping of box girders and T-beams while maintaining high strength, stability, and surface quality under heavy concrete pressure.

Professional Core Technologies and Design Advantages

Customized adaptation design: Precisely tailored to single-box single-chamber or multi-chamber box girders and T-beams. Formwork curvature, angles, and dimensional tolerance are controlled within ≤0.3mm, ensuring full alignment with bridge design drawings without secondary processing.

High-strength sealing splicing technology: Dual locking system with pins and bolts combined with heat-resistant sealing strips ensures tight joints and prevents slurry leakage, eliminating honeycombing, pitting, and surface defects during concrete casting.

High stiffness with lightweight optimization: Thickened Q355B steel plates with reinforced ribs provide strong resistance to lateral concrete pressure while maintaining reduced weight for easier lifting and installation in high-altitude bridge operations.

Modular quick-install system: Rapid locking mechanism enables assembly and disassembly efficiency improved by over 60% compared with traditional systems. Modular design supports flexible configuration for different bridge spans and structural types.

Span adaptability: Suitable for 25m–60m spans including both precast and cast-in-place methods, compatible with highways, railways, and large municipal bridge structures.

Complete system solution: Includes side forms, bottom forms, end forms, inner forms, support systems, tie systems, and lifting components, fully supporting prefabrication plant production and on-site construction.

Applications

Highway bridges: sea-crossing bridges, river-crossing bridges, large-span box girders and T-beams.

Railway bridges: high-speed rail box girders, large-span railway T-beams, precision structural components.

Municipal bridges: elevated bridges, overpasses, and urban transportation structures.

Prefabrication plants: batch production lines for standardized box girder and T-beam manufacturing.
