We are looking to install steel baseplates for a project which is approx. 150m from the coast. We would usually use a HVU2 capsule with either M16 or M20 HAS 5.8 anchor rod or HAS A4 depending on location.
The project we are working on the client wants the anchors bolts to be removeable as they will need to move the baseplates from time to time to move machinery. Then once the machinery is moved the baseplates to be installed on the same fixings.
The baseplates are for an Aluminium demountable structure, our usual uplift is approx. 15-25kN again depending on location and structure size.
I have look at options but the only thing I can see is the HKD-ER SS Drop in anchor, but it states more than 1km from coast.
The other option would be something like HSL-3-R or HSL4
Any ideas what can be used?
Hi, thanks for the question ideally it sounds as though a socket solution would appear to be a desired solution. I take it from your post that consideration has been given for bi- metallic corrosion for the carbon steel rods or stress corrosion cracking for the A4 stainless. I'm assuming the salt / splash zone chances are quite high at that distance it could be corrosive depending upon the location and temperature and the frequency of any 'wash down' . I've attached a copy of our corrosion manual for review . This should give you some guidance as to potential suitable anchor elements for a resin solution or mechanical option and a discussion point with your client as to any material that the anchor should be manufactured from to meet the desired life expectancy.
