English

Subject field(s)
  • Floors and Ceilings
  • Structural Framework
  • Metal Framework Elements
CONT

In many construction projects, standard and long-span metal joists have recently replaced wood and fire-resistant construction due to their strength and fire resistance. Steel joists are not fabricated by a traditional steel fabricator; instead they are manufactured by a supplier specializing in the production and design of steel joists. Steel joists are generally used for floor and roof construction.

English

Subject field(s)
  • Fire-Fighting Techniques
OBS

Single and roof ladders are generally light enough that one firefighter with sufficient upper body strength can usually place the butt end at the point where it will be located for climbing without heeling(steadying) it against the building or another object before raising...

French

Domaine(s)
  • Manœuvres d'intervention (incendies)
OBS

Les échelles simples et les échelles à crochets sont assez légères pour qu'un seul pompier, dont le haut du corps est assez puissant, puisse placer le pied de l'échelle au sol à l'endroit requis sans l'appuyer contre un mur ou un autre objet pour la dresser [...]

Record 4 2012-01-12

English

Subject field(s)
  • Floors and Ceilings
  • Roofs (Building Elements)
  • Metal Construction Techniques
CONT

Types of roof decks... Steel decks. This type is composed of a number of pieces of sheet metal formed with ribs, to give strength and rigidity. The sheets are attached by welding or clips to the roof framing system.

CONT

Steel decks provide a base for several types of floor or roof. A concrete slab may be cast over a steel deck, or a built-up roof may be applied directly over decking. Wood flooring can be applied also, using wood sleepers anchored to the decking.

OBS

steel deck; steel decking: terms officially approved by the Lexicon Project Committee (New Brunswick).

French

Domaine(s)
  • Planchers et plafonds
  • Toitures (Éléments du bâtiment)
  • Techniques de la construction métallique
CONT

Plancher type C.A.P. Éléments en tôle profilée à grande ondes trapézoïdales, fabriqués en usine. Ils sont juxtaposés et solidarisés par des clavettes et remplis de béton de pouzzolane (isolation). Dessus est coulée une dalle en béton armé de treillis soudé formant dalle de compression. Le platelage en tôle est posé sur ossature métallique ou béton ou sur la maçonnerie et on peut circuler dessus aussitôt après la mise en place.

OBS

platelage : Surface structurale sur laquelle la couverture ou le complexe d'imperméabilisation (y compris l'isolant) est appliqué.

OBS

platelage en tôle : terme uniformisé par le Comité du projet de lexiques (Nouveau-Brunswick).

Record 5 2012-01-09

English

Subject field(s)
  • Roofs (Building Elements)
  • Waterproofing (Construction)
CONT

Most vinyl roofing membranes are sealed using hot air, which can be compared to welding metal. The process joins two rolls of membranes at the overlap areas(without using another dissimilar material) to create one monolithic layer that covers the entire roof. The heat-welded, permanently fused seams on vinyl roofing membrane form a watertight seal, and their peel strength can be critical to the roof system's long-term performance against wind forces.

CONT

ROOF technology allows old roof membrane to be renewed without removal. ROOF technology is based upon a thermochemical treatment of bitumen roof coating. With heat applied to a section of roof coating bitumen and bituminiferous mastics start melting. Imbued with own bitumen, roof coating gains improved waterproofing capabilities. Once cooled such coating becomes a tough monolithic layer, smooth and watertight.

CONT

Hot-applied rubberized asphalts consist of proprietary blends of asphalt, mineral fillers, elastomers (natural, synthetic, or a blend of both), virgin or reclaimed oil and a thermoplastic resin. It is applied hot in such a manner as to form an impermeable monolithic membrane over the surface to be waterproofed, which may be concrete, gypsum board or wood. Improved versions of this type of system consist of two coats of rubberized asphalt with a polyester mat in between, called the fully reinforced or two-ply system.

OBS

monolithic layer: term officially approved by the Lexicon Project Committee (New Brunswick).

French

Domaine(s)
  • Toitures (Éléments du bâtiment)
  • Étanchéité (Construction)
CONT

Les bitumes caoutchoutés sont constitués de mélanges particuliers de bitume, de fillers minéraux, d'élastomères (naturels, synthétiques ou un mélange des deux), d'huile vierge ou recyclée et d'une résine thermoplastique. Le produit est appliqué à chaud de manière à former une membrane monolithique imperméable au-dessus de la surface à hydrofuger, qui peut être en bêton, en plaques de plâtre ou en bois. Des versions améliorées de ce type de membrane sont composées de deux couches de bitume caoutchouté et d'un mat de polyester intercalaire; ces membranes sont dites «entièrement armées» ou «à deux épaisseurs».

OBS

couche monolithique : terme uniformisé par le Comité du projet de lexiques (Nouveau-Brunswick).

Record 6 1989-07-31

English

Subject field(s)
  • Fires and Explosions
  • Scientific Measurements and Analyses
  • Analytical Chemistry
DEF

The ability to effect ignition or set on fire.

CONT

These results clearly establish the fact that the incendivity of a spark does not depend on the total energy of the spark.

CONT

Later laboratory measurements... of the incendivity of spark discharges showed that if the uniform field strength in a tank roof space away from any protrusions was 500 kV m-1, then brush discharges having sufficient energy to ignite an inflammable hydrocarbon-air mixture could occur at metal protrusions.

French

Domaine(s)
  • Feux et explosions

OBS

«incendivité» : À partir de l'adjectif «incentif» relevé dans Vie et langage, février 1967, p. 113.

OBS

«pouvoir d'inflammation» : CETT8, t.III Mjb, vol. 13, no. 2, p. 56 (R.A.).

OBS

«inflammateur», n.m. : Substance ou dispositif susceptible de produire l'inflammation, la mise à feu.

OBS

Nous avons pensé à un néologisme comme «inflammatibilité», pour décrire la capacité d'une substance à produire l'inflammation, mais il y aurait danger de confusion avec la notion de l'aptitude de cette substance à s'enflammer elle-même. La même remarque s'applique pour le terme «allumabilité», auquel nous avons aussi songé : on pourrait croire en effet qu'il s'agit de la capacité de s'allumer (verbe pronominal), au lieu de la capacité d'allumer (verbe transitif).
