Title (EN) SLAB FOR A RAISED TECHNICAL FLOOR
(FR) DALLE POUR PLANCHER TECHNIQUE SURÉLEVÉ
Abstract: front page image
(EN)The invention relates to a slab for a raised technical floor, comprising a core with a lower surface and an upper surface each covered with a metal sheet provided with rims that partially cover the edges of the core. The core has a sandwich structure in which the lower layer is a non-combustible heat-insulation layer containing cellular glass and having a low heat conductivity and a low density, while the upper layer is a non-combustible carrier panel containing cement or silico-limestones reinforced with fibres and having good bending and compression resistance. The slab is relatively light but still exhibits good characteristics in terms of bearing capacity and fire resistance.
(FR)Une dalle pour plancher technique surélevé comprend un noyau, dont la face inférieure et la face supérieure sont chacune revêtues d'une tôle métallique munie de rebords recouvrant partiellement les chants du noyau. Ce noyau comprend une structure sandwich ayant: comme couche inférieure, une couche d'isolation thermique non combustible, à base de verre cellulaire, ayant une faible conductivité thermique et une faible densité; et comme couche supérieure, un panneau porteur non combustible, à base de ciment ou de silico-calcaires, renforcé par des fibres, ayant une bonne résistance à la flexion et à la compression. La dalle est relativement légère, mais présente quand-même de bonnes caractéristiques en ce qui concerne la portance et la résistance incendie.
