Product Overview

SOLAIO SVELTO is a polypropylene formwork system designed for rapid installation of lightweight floors in renovation and new construction projects. It is used with trussed joists to create structurally efficient slabs that are lighter than traditional brick or lightweight concrete block floors. The system facilitates easy passage of wiring and small pipes, offers good fire resistance, and can be produced in fire classes 1 and 0 for public buildings without false ceilings.

Technical Specifications

• Material: Recycled polypropylene
• Standard module dimensions: 79.2 cm (length) x 50.8 cm (width)
• Available heights: 9 cm (H-9) and 14 cm (H-14)
• Weight per piece: 1.4 kg (H-9), 1.6 kg (H-14)
• Installation rate: Approximately 2.48 pieces per square meter
• Pallet packaging: 200 pieces per pallet, covering about 80.64 m²
• Accessory: SPALLA polypropylene element used at row starts/ends to contain concrete during casting, available in matching heights

Load Categories and Structural Parameters

The system is classified into load categories based on usage environment:

• Category 1: High occupancy areas (conference halls, cinemas, theaters, churches, shops, fixed seating stands) – 400 Kg/m²
• Category 2: Medium occupancy areas (restaurants, cafes, banks, hospitals, public offices, barracks) – 300 Kg/m²
• Category 3: Low occupancy areas (residential rooms, hotels, offices not open to the public) – 200 Kg/m²

Structural calculations assume trussed joists with 12 cm base and 2.5 cm height, concrete strength R’ck 250 Kg/cm², steel FeB 44K, and welded mesh Ø5 mm with 20x20 cm spacing.

Installation Procedure

1. Install trussed joists at specified spacing with shoring.
2. Place and interlock SOLAIO SVELTO modules onto joists.
3. Install SPALLA elements at row ends and where modules are cut lengthwise to prevent concrete overflow.
4. Lay welded mesh (Ø6 mm, 20x20 cm grid) on top of modules, including overlaps and waste.
5. Pour concrete (Rck = 250 kg/cm²) to form the structural topping layer of specified thickness.

Thermal and acoustic insulation materials can optionally be included within the slab layering.

Applications

• Residential floors
• Industrial buildings and prefabricated structures
• Garages and basements
• Intermediate floors
• Attic floors
• Sloped roof floors
• Cemetery construction
• Cold storage cell construction
• Sanitary voids

Advantages

• Lightweight and easy to handle, enabling rapid installation (up to 200 m² per day by a 3-person team)
• Replaces traditional brick or lightweight concrete blocks, reducing structural dead weight
• Allows passage of cables and small pipes within the slab
• Good mechanical strength and solidity; supports workers and concrete weight during installation
• Modules interlock securely for stability
• Can be easily cut lengthwise and widthwise on site
• Fire resistance suitable for public buildings, with optional higher fire classes

Packaging and Handling

Modules are supplied on wooden pallets (120x80x230 cm) with 200 pieces per pallet, covering approximately 80.64 m². SPALLA elements are packed in boxes of 50 pieces.

Notes and Recommendations

The provided load values and tables are indicative and generic; specific cases should be discussed with the manufacturer to determine the most suitable solution. Structural calculations are based on standard joist and concrete parameters as described. Technical data sheets and specifications are available on the manufacturer's website: www.ferracinsrl.it.

Additional Tabular Data Summary

The document includes tabular data related to categories and size ranges, likely concerning pipe or tubing specifications:

• Category 2:300 with size ranges 478–501 mm and 502–525 mm
• Category 3:400 with size ranges 358–381 mm, 382–405 mm, 406–429 mm, 430–453 mm, and 454–477 mm

Parameters per entry include diameter ranges (mm), a fixed value of 63.6 (likely a dimension or standard), thickness values (20 or 22 mm), numeric values (3.5 or 5.5), and pressure or strength ratings (210 or 260, and 200).

Observations indicate that entries with thickness 20 correspond to lower numeric values (3.5 and 210), while thickness 22 corresponds to higher values (5.5 and 260). Category 3:400 entries have two parameter sets depending on thickness. This data likely relates to pipe or tubing specifications, including diameter, thickness, and pressure ratings.

Note: The tabular data lacks explicit section titles or explanations, so interpretation is based on context. Additional clarification from the manufacturer would be necessary for full understanding.
