    can you take all the formwork down when the concrete slab is set and can you reuse the timber!

    • @bmformworkconcreteconstruc9783
      @bmformworkconcreteconstruc9783  Рік тому +1

      Yes, it would be very expensive if we couldn't re-use anything. In residential formwork the key to making money as a business owner is maximising how many uses you get from all your materials. You have to do about 6 jobs to cover the cost of one job worth of materials including props.

      Good question. Ask someone who does this in your area (will change depending on the local products used) but for it to be covered by insurance you can ask an engineer to give you this.

      Keep all the joints sealed up so it's water tight. Use form oil just before you pour. Keep everything clean. Make sure your reo bar chair don't bite into the timber and leave an imprint.

  • @davidparker2173
    @davidparker2173 5 місяців тому +1

    I think there would be a whole lot of ways to set that up, and I'm just figuring it. Maybe just start with a lot of steel I beams permanently installed first, then lay the sheeting on top of that with 4 to 6 inch aircrete for weight reduction, and primarily rely on steel strength for structure, but I'm just guessing.

      @@fergzmack6963 hey mate, yes you are correct, you need to prevent lateral movement of the suspended slab. I did that with raking props which are not shown in video. You can use scaffold tube or peri ratchets but there is no need here. It is also system dependent. I am framing with timber, I know how to lock it in without the need for scaffold tune and ratchet straps. The balcony is only 2.8m it is tied into the job with steel strapping at deck level. I will make sure I show in future videos. It also depends how you pour the conc. The is more lateral force if the concrete pushes off something into the edgeboards. You have to find where it will separate from main deck and lock it there. In my case it was the timber splice. So I nailed off the sheets with extra nails, raked long props from balcony to ground and strapped main deck to other rooms. There was no possible movement.

      @bmformworkconcreteconstruc9783  2 роки тому

      frames can be much easier for inexperienced guys. But if you can do it without them it is far quicker using props. only have to carry 4 props vs 2 frames, 2x braces, 8x jacks then set 8x jacks. Frames also destroy site access and do not fit great on a truck or on forklift tines. I usually just use frames for beams, high sections and large balconies. I prefer quickstep or layher than frames(standard and ledgers) as they more versatile.
