SLIMFLOR® Fielders Fire Protection

May 4, 2017

FIRE DESIGN OF FIELDERS SLIMFLOR® CONSTRUCTION (BEAMS)
This fact file assists designers with designing their Asymmetric Steel Beams for fire conditions.
When undertaking a fire design for a SlimFlor® design both the slab and beam sections need to be considered. This fact file discusses the fire rating of the Asymmetric Steel Beams, for details on fire rating the CF210® slab  refer to Fielders Fact File F.3.6b. 

 

FIELDERS SLIMFLOR®
SlimFlor® utilises Fielders CF210® flooring profile in conjunction with Asymmetric Steel Beam Sections (ASB) to provide a floor system with a reduced construction zone. It does this by combining the floor slab and supporting structure in the same plane, providing a lightweight, versatile, long spanning floor system.

 

ASYMMETRIC BEAMS
Due to the nature of the CF210® resting on the bottom flange of the ASB and encasing the beam in concrete (leaving only the underside of the bottom flange exposed) the beam is provided with a degree of fire protection. This level is detailed in the Fielders Fact File F.3.5 – Asymmetric Beams for SlimFlor® Construction. To achieve higher levels of fire protection the bottom flange can be painted with an intumescent paint or covered with fire rated boards or vermiculite sprays. Specifications for the paint are detailed below.

SURFACE PREPARATION

•    Abrasive blast clean to Sa2.5 (ISO 8501-1:2007) or SSPC-SP10. If oxidation has occurred between blasting and application, the surface should be re-blasted to the specified visual standard. Surface defects revealed by the blast cleaning process, should be ground, filled, or treated in the appropriate manner.
•    A sharp, angular surface profile of 50-75 microns (2-3 mils).
•    All corners, edges should have a 2mm radius.
•    Stripe coats should be applied to all welds, lap joints, plate edges, corners, sharp edges, and any other areas.

PRODUCT DESCRIPTIONS
Intercure 200 - Epoxy Zinc Phosphate primer
Interchar 1260 – Water based Acrylic Intumescent
Interthane 870 – Semi gloss polyurethane topcoat

 

SERVICE PENETRATIONS
Integration of services can be achieved by providing an opening through the beam midway between the ribs of the CF210® decking. The size and location of the web openings must meet the following requirements;

• Elongated openings up to 160 mm deep by 320 mm long centrally between the ribs over the middle half of the beam span, but not within 1500 mm from the supports.• Alternatively, provide circular openings up to 160 mm diameter, but not within 1000 mm from the supports. To offer fire protection through the void a fire collar can be placed around the pipe as shown in Figure F.3.6.2.
