How do you lay concrete slabs for 1st floor building. How do the slabs balance.?

Question

Are they bolted in, just laid onto the steel columns or are they fixed in a certain way. If you can help please provided a link on the net that i can go to that will show a few pictures in close how it is done. Thank-You.

Answer 1

with T beams and 40n concrete blocks in between each beam. then a layer of sand and cement screed is leveled over them all to produce your finished floor. http://www.wrightbuildingsupplies.co.uk/products/beams_lintels.htm

Answer 2

The reason you shouldn't use hardwood on concrete is because it will draw moisture through the concrete into the wood and ruin your floor over time. You could go with a synthetic wood floor which would avoid this problem. Another choice would be cork as long it has a non wood backing which most cork does since it's cheaper to make this way. Cork installs like a synthetic wood floor (Pergo) where as it doesn't get nailed to the substrate but instead "floats" over top and the pieces are either glued together or snap locked together. You could also put carpet down with a rubber backing or vinyl sheet goods. There are tons of choices...go to a flooring showroom (not a home depot) and look around for ideas and speak with a rep there

Answer 3

If the slab is on the ground you just pour it on a compacted bed of gravel with a grid of temperature steel. If the slab is suspended ie you can walk under it, then you had better have the entire system desined by an engineer. You will also need drawings and specifications for the entire project as well as a building permit.

Answer 4

There are a couple of different methods of attaching floor slabs to the different floor levels, depending on the design of the building and slabs. However, FIRST floors are typically supported from the foundation, not the columns.

Answer 5

They will be fastened somehow. They might have flanges welded to their internal reinforcing steel and cast into the concrete for welding to the steel frame or they could have anchors to be bolted on. Often they make a joint at the support an after installing support and extra rebar fill it with concrete when it is in place. Every system by every manufacturer is different. You could choose a precast concrete manufacturer/supplier and visit their website

This one is fairly typical.

This is a different system.

Every precast supplier has a different system. These are both suitable for larger buildings.

Answer 6

i think you mean a beam and block floor in this form of flooring you have concrete beams that are laid down at the required level ..these beams are like an upside down T .....they are spaced at about 450 ,,600 centres ...then solid concrete blocks are laid in between the beams to form the floor ..in practise its reasonably easy to do .. then the screed is laid on top at a later time

Answer 7

a metal frame is placed between the RSJ's

the frame is corrugated so has strength

then concrete is poured in and reinforced with steel mesh.
