Drop-In Cassette Panel Pedestrian Deck per Eurocode, ASTM A709 & AS 5100 Rapid

A pedestrian corridor is a type of steel-structured passage specifically designed for short distances (6–60m) and light loads (≤5kN/m²), connecting two buildings or spanning obstacles below. Its core features include a narrow deck (1.5–3.0m), high natural frequency (≥3Hz), and compact building clearance. According to the degree of enclosure, it can be classified as fully enclosed (temperature-controlled, soundproof), semi-enclosed (canopy, open railings), or fully open (outdoor non-slip surface), and it is widely used in hospitals, campuses, commercial complexes, and parks.

1.Application Scenarios

2.Product Highlights

l Detachable Railing Posts: The posts are inserted into pre-embedded sleeves at the bridge edge, locked with spring pins, requiring no bolts, and can be replaced in 10 seconds if damaged.

l Invisible Drainage System: The bridge deck's cross slope directs water to downpipes inside decorative end posts, with no exposed pipes under the bridge.

l Bird-Resistant Canopy: The enclosed corridor roof has a slope ≥35°, or anti-bird spikes are installed, preventing birds from perching and defecating.

l Handrail Preheating and Anti-Freezing: Stainless steel handrails are equipped with self-limiting heating cables (10W/m) inside, maintaining a surface temperature of 5–10°C in winter.

l Step-Free Threshold Design: Both ends of the corridor are level with the building floor, or a 1:20 slope is provided, with ramp panels embedded where there is a height difference.

l Integrated Louver Ventilation: Enclosed corridor sidewalls have adjustable aluminum louvers for natural ventilation during transitional seasons.

3.Product Materials

ü High-strength lightweight carbon steel main frame: Adopts fine processed structural steel, possessing good bending resistance and tensile performance, ensuring overall structural firmness while controlling overall weight effectively.

ü Anti-slip wear-resistant walking deck: Uses composite anti-slip plate or patterned steel plate, with strong friction resistance, avoiding slipping risks in rainy and snowy weather, comfortable and durable to walk on.

ü Anti-rust protective coating material: Adopts multi-layer anti-corrosion spraying process, isolating air and moisture erosion, slowing down material aging and extending overall service cycle.

ü Safe enclosed guardrail accessories: Matches high-strength alloy guardrails and silent connecting parts, stable in structure, smooth in appearance, effectively guaranteeing walking safety on the bridge.

ü Environmental sound insulation and noise reduction auxiliary materials: Partial sections are equipped with silent buffer materials, reducing walking and passing noise, improving overall passing comfort.

4.Design Features

Ø Human-Induced Vibration Control: Fundamental frequency ≥3Hz (vertical), ≥1.5Hz (horizontal); Tuned Mass Damper (TMD) provided if necessary.

Ø Differential Settlement Adaptation at Both Ends: Bearings allow 15mm settlement on one side without generating additional internal forces, achieved through arched sliding surfaces.

Ø Wind Comfort Check: For enclosed corridors, wind vibration coefficient β=1.2~1.5 is considered, with peak acceleration limited to ≤0.3 m/s².

Ø Glass Fall-Prevention Redundancy: Laminated glass, even if broken, keeps fragments adhered to the PVB film, preventing falls and injuries.

Ø Fire Escape Assurance: Fire-rated doors (Class A) installed at both ends of the enclosed corridor; structural fire resistance ≥0.5h (no fireproof coating needed).

Ø Night Guidance Lighting: LED strips hidden under handrails (3000K color temperature), illuminance ≥20 lux, with no upward light emission.

5.Core Advantages

⭐Zero Reinforcement to Existing Building: Bearing reaction ≤30 kN, directly anchored to existing beams and columns, no additional reinforcement required.

⭐100% Factory Pre-Assembly: Railings, glass, lighting, and drainage completed in the factory; on-site only hoisting and installation needed.

⭐All-Weather Construction: Full bolted connections with temporary magnetic fixing; work can proceed in rain or at night.

⭐Low Cost for Later Color Change: Powder coating can be re-sprayed; surface can be refurbished by brushing or spraying.

⭐Invisible Pipeline Integration: Cable trays hidden inside handrail posts or ceiling layers, no exposed cables on the façade.

⭐Seismic Vibration Absorption: Universal bearings at both ends allow ±50mm relative displacement; the corridor does not transmit seismic forces.
