摘要:
The invention relates to a floor structure (1) with a gap for technical equipment, including a metal carrier structure made of metal bearing beams (2) and struts (3, 3') arranged between the metal bearing beams, both having webs with passage openings (4, 4') for ducts. A ceiling (7) is suspended underneath the metal carrier structure. An upper surface of the floor is made of slabs (110, 110') that are carried by adjustable bearings (6) directly on the struts. It is thus possible to form a continuous gap for technical equipment that extends from the lower surface of the slabs to the upper surface of the suspended ceiling without additional horizontal separation therebetween. At least certain slabs (110, 110') are easily removable so as to provide access from the top to the gap for technical equipment.

Un mur coupe-feu comprend une paroi (12) construite à l'aide de panneaux (14) résistants au feu, une structure porteuse (16, 16') métallique indépendante de chaque côté de la paroi (12), un système d'ancrage pour chacune des deux structures porteuses (16, 16'), avec des points d'ancrage entre ladite paroi (12) et ladite structure porteuse (16, 16'), et au moins un moyen de détection incendie (40) associé à chaque système d'ancrage de façon à provoquer, en cas d'un incendie, une rupture desdits points d'ancrage du côté de la paroi (12) qui est exposé à l'incendie. L'écartement entre les deux structures porteuses (16, 16') est égal à au moins deux fois l'épaisseur d'un panneau (14) résistant au feu, et la paroi (12) est agencée au milieu entre les deux structures porteuses (16, 16'). On présente également un nouveau panneau (14) sandwich résistant au feu et un nouveau type de joints entre panneaux (14) résistants au feu.

The panel (2) has a metal sheet (10) covering an insulating core on a face, where the core is made of insulating material. Tabs (4) made of insulating and rigid material form two opposite edges of the panel. The tabs include a hole or orifice (18) close to each corner of the panel, where the hole is perpendicular to a face of one of the tabs forming an edge of the panel and close to a face of the core opposite to a face of the metal sheet. The hole or orifice cooperates by engagement with a dowel pin placed in corresponding hole of an identical adjacent panel.

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.

The invention relates to a covering and fire-protection device for metal girders used in buildings. The casing comprises four modular elements, namely: first and second U-shaped section elements (10, 12) closely fitting the flanges of the girder (4) and positioned facing one another; and third and fourth straight section elements (20, 22) each connecting the first and second elements (10, 12) and closing the essentially rectangular compartment. The casing is formed by fire-resistant panels (14, 18, 19, 24) that are covered with a metal sheet (16, 26).

The invention relates to a firestop screen suspended ceiling including panels with an insulating non-combustible core and having lower and upper surfaces each covered by a metal sheet. At least one edge of the core includes a connection key made of a reinforced mineral material and along which extend the edges of two metal sheets. Two panels are arranged so that two connection keys face each other, thus defining lower and upper connection grooves separated by the connection keys. A metal profile is provided in each of said two connection grooves and is connected to at least one of the two connection keys and covers the seam between the two connection keys. The connection metal profile secured in the upper connection groove is used as a fastener for a suspending means.
