Open floor slabs YX38-152-914, YX76-305-915, YX51-342-1025, special-shaped steel plate steel structure composite load-bearing floor slabs

Description

1. YX38-152-914 open floor deck

Specification parameters

Wave height/wave distance/effective width: 38mm/152mm/914mm

Expansion width: 1250mm, utilization rate 73.12%

Thickness range: 0.75-1.5mm (commonly 0.8mm, 1.0mm)

Cross-sectional characteristics (taking 1.0mm thick as an example) :

Moment of inertia of the cross-section: 10.21 cm⁴/m

Section resistance moment: 12.56 cm³/m

Performance characteristics

Convenient construction: No need to remove formwork, multiple layers of concrete can be poured simultaneously, shortening the construction period by 30%.

Economy: The unit price is approximately 48.5 yuan per meter (1.0mm thick galvanized sheet).

Application fields: Industrial plants, commercial buildings, public facilities (such as airports, stadiums).

Note: For spans greater than 3 meters, temporary supports need to be added. Fire protection measures should be taken separately (such as spraying fireproof coatings)..

2. YX76-305-915 open floor deck

Specification parameters

Wave height/wave distance/effective width: 76mm/305mm/915mm

Expansion width: 1250mm, utilization rate 73.2%

Thickness range: 0.8-1.5mm (1.2mm is recommended for large spans)

Cross-sectional characteristics (taking 1.0mm thick as an example) :

Moment of inertia of the cross-section: 128.88 cm⁴/m

Section resistance moment: 33.56 cm³/m

Performance characteristics

High load-bearing capacity: The maximum unsupported span reaches 3.5 meters, making it suitable for applications in high-cold regions such as geothermal laying.

Durability: The galvanized coating is ≥80μm, and the anti-corrosion life exceeds 20 years.

Cost comparison: It saves 5% of material costs compared with similar plate types (such as YX76-344-688).

Application fields: Logistics warehouses, multi-story factories, large commercial complexes.

3. YX51-342-1025 open floor deck

Specification parameters

Wave height/wave distance/effective width: 51mm/342mm/1025mm

Expansion width: 1250mm, utilization rate 82% (one of the highest in the industry)

Thickness range: 0.8-1.5mm (commonly 1.0mm)

Cross-sectional characteristics (taking 1.0mm thick as an example) :

Moment of inertia of the cross-section: 65.26 cm⁴/m

Section resistance moment: 24.75 cm³/m

Performance characteristics

Ultra-high utilization: With an effective width of 1025mm, it saves 10% of the cost compared to the YX51-250-750.

Lightweight: The weight per unit area is 30% lower than that of traditional formwork, and the strength is increased by 20%.

Construction advantages: Suitable for multi-story steel structures with rapid construction, shortening the construction period by 40%.

Application fields: Grain storage facilities, industrial plants, prefabricated buildings.
