R_2,k capacities can be calculated as R_2,k= R_1,k x (nb of dowels - 1) / (nb of dowels).

The top dowel is not considered for the uplift capacities as it is placed in an open hole.

Installation

Fixing

On supporting wood member: TUS

CNA annular ring-shank nails dia. 4.0 x 50 mm or CSA screws dia. 5.0 x 40 mm.

On supported member: Steel dowel S235JR type STD12

TUS12: dia. 8 mm type STD 8.
TUS16 to 28: dia. 12 mm type STD 12.

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

TUS: wood/wood fastening only with nails/screws

Installation

Make a vertical notch in the joist end (width 6mm for TUS12 and 9mm for TUS16 to TUS28),
Mark the position of the dowels on the joist before drilling holes - diameter of the hole according to the diameter of the dowel
Insert the top dowel in the joist
Route a 6mm deep pocket in either the joist end or the header. This is not compulsory, it is used to improve the aesthetic of the connection
Fix Install the joist onto the concealed beam hanger by hooking the joist onto the concealed beam hanger. Top dowel hooks into slotted top hole on the concealed beam hanger.
Install reamining dowels.the concealed beam hanger to the header with nails or screws
