I have a 150mm metal deck floor with 90mm of concrete above the deck. According to previous comments I have tried to use HST3 anchor but the screen I'm fixing is 1.9m tall with crowd loading and needs to be demount-able. Is it possible to use a HDK socket, I can't find this in the Profis software I'm using?
Thank you for your question, the HKD and HSC-I internally threaded sockets are both contained within the Profis Engineering software. The base material thickness of 90 mm however is below the minimum thickness requirements for these products and hence they will not be an active option. Additionally, the HKD is not approved for single point fixing within areas of concrete that is deemed to be in tension / cracked. Of course, you are at liberty to undertake your own site testing and make an Engineering Judgement based upon the conditions ‘as found’. We would refer you to BS8539:2012 for further information should you wish to pursue that option.
