VEW1 ‘Angle’ Windposts
Verified by manufacturer 23 days ago
BS EN 1090 EXC2
Certificate type
Angle wind posts.
Application
Both the VEW1 and VEW2 type windposts span vertically between floors and the design will usually include a positively fixed base and a top fixing that will allow differential movement between the structure and the masonry.
Description
The VEW1 range of windposts are of angle section where the inner leg ‘A’ of the post is built into the inner leaf with the return leg ‘B’ sitting in the cavity. They are generally used for heavily loaded conditions or for small cavities where the VEW2 type post may not fit.
The windposts are usually designed as ‘simply supported beams’ with a maximum allowable deflection of span/360 and a maximum allowable design stress of 193.75 N/mm² (includes +25% allowance for transient windload).
Where deflection is the limiting factor windposts may be designed as a ‘propped cantilever’, using this method reduces the deflection of the windpost considerably but requires a much larger baseplate.
One-way windpost tie usually only required when the VEW1 is being used at a movement joint location or at an opening. Not supplied as standard please specify if required when ordering. Two-way windpost ties usually supplied 200 mm long. The ties can be supplied with a debonding sleeve for windposts being used at movement joint locations.
