Anchors for frame uprights

AH anchor and its US40/50/10G washer (sold separately) are recommended for reinforcing the corners of wood-frame walls subjected to uplift forces. This connector ensures a significant absorption of tensile load. Moreover, its low width allows it to be fastened to a 45 mm wide upright.

Features

Material

AH29050/2-FR: galvanized steel S250GD + Z275 according to NF EN 10346.
US40/50/10G washer: steel S235JR + hot-dip galvanized finish.

Benefits

Low-width anchor for use in frame uprights 45 mm wide.
Anchors the wood-frame wall solidly into the ground (recommended in seismic zones).
Reinforces the upright-lower plate connection by preventing the uplift of the upright.

Thus, energy is dissipated in the panel through the stitching.

Application

Suitable On

Wood, concrete

When to Use

Used in wood-wood and wood-concrete assemblies

For configuration 1, 1 WA M12-119/20 or AT-HP + LMAS12/150 are suggested.

⁽¹⁾The published characteristic capacity is based on instantaneous load duration and service class 2 according to EC5 (EN 1995) – k_mod = 1.1. The bolt capacity shall fullfil (2.33 x F_d / N_r.d)^1.5 + (0.79 x F_d / V_r.d)^1.5 < 1

⁽³⁾The published characteristic capacityis based on instantaneous load duration and service class 2 according to EC5 (EN 1995) – kmod = 1.1. The capacity of WA anchor is included with the following hypothesis of an isolated single anchor in non-cracked concrete C20/25 with normal reinforcement: edge distances are over c_cr.N=110 mm, c_cr.sp = 215 mm and spacing is over s_cr.N=220 mm, s_cr.sp = 430 mm

For other load duration and service class, please refer to the ETA to get more accurate capacities

R_lat,k = Characteristic load-carrying capacity per shear plane per fastener (CNA or CSA)
n = n_ef = effective number of fasteners acc. to Eurocode 5 (8.3.1.1)
Required calculated pull-carryring capacity for bolt: N_R.d = F_1,d x 2,33 ; the required calculated shear capacity for bolt V_R.d = F_1,d x 0,79

AH9035 is only usable for connection to rigid support.

Installation

Fixing

On concrete:
Configuration 1 or 2:

Mechanical anchor: WA M12-104/5 dia. 12
Chemical anchor: AT-HP resin + LMAS M12-150/35 rod.

Configuration 3:

Mechanical anchor: WA M12-219/120
Chemical anchor: AT-HP resin + LMAS M12-150/35 threaded rod per metre and tfix minimum 110 mm.

On wood:

CNA annular ring-shank nails dia. 4.0 x 35 or dia. 4.0 x 50 mm (the number of nails to be used depends on the application configuration).

Installation

Use only the fasteners specified for each of the configurations while precisely respecting the edge distances.
The US40/50/10G washer must be used to guarantee the forces given in the table below.

This prevents the AH anchor from unfolding during uplift. The washer is sold separately.

RECOMMENDATIONS FOR USE:
It is recommended to use the AH anchor + US 40/50/100 washer at the end of each wood frame, at the backing of the uprights and perpendicular to each opening. This recommendation does not replace a verification carried out by a competent engineering firm.
