T-beam Formwork

Shaanxi Flourish Industrial Co., Ltd.''s Steel T-beam Formwork redefines medium-small span bridge efficiency with its T-beam-exclusive "web-flange integrated" system-solving "joint misalignment" and "slow assembly" pain points of generic steel formworks. Crafted from high-strength Q355B steel, it delivers ±1.5mm linear precision for 10-40m T-beams, 35% faster assembly than traditional formworks, and 280+ reuses-trusted by highway, rural road, and overpass contractors globally.

1. Web-Flange Integrated Forming

Patented "one-piece transition" design eliminates gaps between T-beam web (thickness 200-400mm) and flange (width 800-1600mm). Unlike split formworks (web and flange assembled separately), it avoids concrete leakage at joints (leakage rate ≤0.5% vs. 5% for split types) and ensures flange flatness ≤1mm/m-critical for T-beam load distribution.

2. Medium-Span Optimized Load-Bearing

"Triangular rib + horizontal bracing" structure (rib thickness 10mm, spacing 300mm) supports 85kN/m² concrete pressure-perfect for C30-C50 concrete in 10-40m spans. 4-point bending test shows deflection ≤2mm under full load, outperforming 箱梁模板 (designed for long spans, overkill for T-beams, leading to 20% higher cost).

3. Snap-Lock Rapid Assembly

Modular panels with stainless steel snap-locks (locking time 8s/piece) enable 2 workers to assemble 3 T-beams (30m span) daily-35% faster than bolt-connected formworks. No on-site welding: align panels, snap locks, and verify precision (10 minutes per beam), cutting labor cost by 40%.

4. Durable & Cost-Effective

80μm hot-dip galvanizing (full-surface coverage) resists salt spray ≥1800h-suitable for rural road humidity and coastal overpasses. 280+ reuses reduce per-project cost to 1.2/sqm (1/3 of disposable formworks). Maintenance only needs annual lock lubrication (0.2/sqm/year), lower than steel box girder formworks ($0.8/sqm/year).

5. Tool-Free Adjustment for T-beam Sizes

Telescopic flange panels (adjustable width 800-1600mm, 50mm increments) and removable web inserts (thickness 200-400mm) fit 90% of medium-span T-beam designs. Converting a 300mm web to 400mm takes 1 hour (vs. 1 day for custom split formworks).

1. Installation Steps

Step 1: Place support frames (level error ≤1mm) → install web inserts (match T-beam thickness)

Step 2: Attach integrated panels → snap locks (verify alignment with laser level)

Step 3: Extend telescopic flanges to target width → lock with auxiliary pins

Step 4: Apply water-based release agent (1 coat) → check for gaps (use rubber strips if needed)

2. Demolding & Maintenance

 Demold: Unlock snaps → lift panels (use built-in hooks) → remove inserts (2 workers/beam, 15 mins)

 Maintenance: Rinse with water (remove concrete residue) → lubricate locks with silicone oil (monthly) → touch up galvanizing scratches (annual, cost $0.5/sqm)

1. Can it handle T-beams longer than 40m?

No-our formwork is optimized for 10-40m medium spans. For longer spans (＞40m), we recommend our steel box girder formwork (designed for heavy loads in long spans).

2. How is it different from steel box girder formwork?

Box girder formwork is for long spans (＞40m) with complex chambers, while ours is T-beam-exclusive: lighter (single panel 45kg vs. 60kg for box girder), cheaper (30% lower cost), and faster to assemble (35% time saved).

Choose Shaanxi Flourish's Steel T-beam Formwork-not a repurposed box girder or pier formwork, but a T-beam-exclusive solution for medium-small span bridges. Build faster, cheaper, and more precisely!
