Tech/Engineering - Construction / Civil Engineering / Installation of smoke ventilation exhaust
French term or phrase: retour d'équerre
- Souche de toiture :
- Réalisation de cette souche suivant DTU 43.3.
- Découpe soignée du complexe isolant et étanche existant.
Ce complexe est, à priori, le suivant :
- Plateaux supports d'étanchéité en acier galvanisés à chaud.
- Isolation thermique à priori en laine minérale d'épaisseur 80mm.
- Étanchéité multicouche bitume élastomère.
- Fourniture, pose et fixations sur les chevêtres définis ci-avant, d'une costière métallique isolée, double peau, en tôle d'acier galvanisé à chaud, épaisseur 25/10ème, de dimensions intérieures environ 1,00m x 1,00m.
La partie supérieure des relevés de costière sera horizontale et comportera 2 plis raidisseurs.
Toutes les sujétions de pose, de réglage et de fixations de cette costière seront dues dans le cadre du présent lot.
- Réalisation des relevés d'étanchéité, de hauteur conforme au DTU N°43.3, en périphérie de cette costière métallique et suivant les mêmes prescriptions que celles déjà définies à l'article 04.22.3.
Ces relevés seront protégés en tête par la partie horizontale supérieure de costière.
- Habillages intérieurs aux 4 sens de cette trémie au niveau de la sous-face des bacs de couverture, réalisés en tôle d'acier galvanisé à chaud et thermo laquée de teinte BLANC RAL, d'épaisseur 15/10ème, pliée et fixée sur les chevêtres de toiture.
Ces habillages intérieurs seront réalisés en 4 éléments à assembler sur le chantier et comporteront des **retours d'équerre** en partie basse pour couvrir les tranches découpées des plateaux de couverture.
Ils viendront également habiller l'épaisseur du complexe de toiture.

I think I see what they mean: the roof opening will be lined with steel which will be bent at right angles at the bottom. Any suggestions?
In case you're not familiar with certain terms: costière is curb or frame, relevés d'étanchéité is flashing, trémie is an opening.

I think the diagrams on page 44 of the quoted DTU 43.3 may be relevant:

right-angled return
Explanation:
or: a return at 90°

I think the 'return' simply refers (as often in technical areas) to the folded part, which is very often a 'return' in EN.

right angles


Explanation:
This is a commonly used term when describing construction of large or small projects. Perhaps the definition didn't pop up because of the slash between 'd' an the apostrophe.

Example sentence(s):
  • These interior components will be assembled in 4 steps at the construction site and built at right angles on the lower part of the project.

neutral  Tony M: I think there's more to this then meets the eye; certainly, 'd'équerre' often means 'at right angles' — but I think the 'retour' cannot simply be omitted.
