Instalacja

Montaż

Fixing

On supporting wood member: TU/TUB/TUBS

CNA annular ring-shank nails dia. 4.0 x 50 mm or CSA screws dia. 5.0 x 40 mm.
Lag screws and bolts dia. 10 mm only for TUB/TUBS.

On supported member: Steel dowel S235JR type STD12

TU12: dia. 8 mm type STD 8.
TU16 to 28: dia. 12 mm type STD 12.
TUB/TUBS: dia. 12 mm type STD 12.

The length of the dowels is less than or equal to the width of the supported joist.

TU: wood/wood fastening only with nails/screws.
TUB: wood/wood fastening only with nails/screws or lag screws.
TUBS: wood/wood fastening only with nails/screws or lag screws.

Concrete and steel substrate:

It is not recommended to use hangers on concrete or steel substrate as the size of the bolts makes the distance from the edge of the wood to the dowels non-compliant with Eurocode 5.

Installation

Réaliser une entaille verticale dans la poutre portée (largeur 6 mm pour le TU12 et largeur 9 mm pour les TU16 à TU28),
Identifier la position des broches sur la poutre avant de percer transversalement,
Insérer uniquement la première broche dans la poutre sur la partie supérieure (diamètre de perçage fonction du diamètre de la broche),
Réaliser un lamage d’une profondeur de 6 mm dans le support. Ce lamage n’est pas obligatoire, il permet d’améliorer l’esthétique de l’assemblage,
Fixer l’étrier sur le support à l’aide de pointes ou de vis,
Présenter la poutre portée de manière à placer la broche déjà en place dans l’encoche de l’étrier,
Mettre en place les broches restantes.
