Concrete flooring dimensions

[Ron Avery]

I have done a search, honestly I have[:P] but I cannot find anywhere on here or by Googling the dimensions particularly the width that has to be used for those preformed concrete blocks that drop into the L shaped beams for a concrete floor.

I want to replace the old sagging beams in ground floor caves and make a terrace above as we have stunning views.  There is some latitude with the dimensions of this terrace, it is 5 m wide ( length of beams) and will be about 6m long but I would like to use whole blocks so I would like to calculate the ideal length to arrive at this,  including blocks and beams.  Any links to websites or advice welcomed.

Thanks

I'm pretty sure that any standard parpaing will do the trick. Alternatively you can get lightweight entrevous (the bits that go between the beams) from companies like Rector. ( http://www.rector.fr/ ) For these the beams (poutrelles) need to go at 60cm centres.

These links gives access to a lot of technical info:

and this one is about making a terrace above a vide sanitaire.

Sometimes its not possible to use whole" hourdis"and a coffrage is used to finish off

one end .The poutrelle is about 12 cms in width, they vary it depends on the maker.

You set the first "hourdis" with about 2.5cms resting on the wall then put on the wall

your poutrelle,measure both ends so that your poutrelle is square on then repeat the

 process for the next row dont fill in untill you have all your poutrelles in place

(because you may have to make small adjustments).If you base your poutrelles on

60cms centres you should be able to work how many poutrelles and hourdis you need

Hourdis vary in depth depending on the span that you have and normal agglo won't  fit

 on the lip of the poutrelle correctly

the process above is for new work with old work youstart with a poutrelle against the wall
