VEW2 ‘Channel’ Windposts

Designed to sit in the cavity itself and tied to both inner and outer leaves, VEW2 Windposts are ideal for more lightly loaded walls.

Introduction

The GA VEW2 range of windposts are of channel section where the post sits in the cavity of the wall, they are generally used for lighter load conditions than the GA VEW1 type posts. 

The use of a GA VEW2 Windpost is governed by the size of the cavity and the load to be supported i.e. it may not be possible to increase the section of the post and therefore its load capacity due to the size of the cavity.

GA WPTC

The GA WPTC one way tie is clipped to VEW2 edges to tie into both block and brick courses. 

VEW2 WINDPOST CONNECTION EXAMPLES

Example 1

Head fixed using M12 FBN II Anchor into concrete slab.

Base fixed using M12 FBN II Anchor into concrete slab.

Example 2

Head fixed using M12 BSB Bolt into R.H.S.

Base fixed using M12 Isolated Setscrews into steelwork.

Example 3

Head fixed using M12 Coachscrew into timber wallplate.

Base fixed using M12 FBN II Anchor into concrete slab.

Performance Tables

Windposts are designed as simply supported beams with a maximum design strength of 230N/mm2 and a maximum deflection of span/360. Design resistances should be compared with factored loads. Recommended loads include a variance factor of 1.5
