Protected structures fall into three essential classifications: stackable squares, huge center forms and sheet froth frameworks. Stackable squares are preassembled; however sheet froth items need some arrangement. Huge center molds are stackable squares that structure the concrete into a post-and-pillar divider. Sheets froth situation utilize inflexible protection, as a rule expelled polystyrene. The sheets are gotten together with spacers that hold them 6 to 10 in. separated. This work should be possible by the temporary worker or the vendor.
At the place of work, stacking the squares or sheet froth gatherings is a lightweight errand. That saves time and energy on all positions. At the point when the site is secluded or you cannot get a truck extremely close, the lightweight units can be a genuine back saver. While the work is actually a breeze, the work actually takes arranging. For a large portion of the items, keep these straightforward principles:
- Secure wood direct plates to the balance.
- Start laying block at a corner.
- Stagger block joints.
- Stack holes straightforwardly over each other.
- Brace the dividers well.
During layup, rebar is put on a level plane on the metal or plastic cross individuals from each course. Vertical rebar dispersing relies upon the stature of the divider and square plan.
Supporting prerequisites shift drastically between items. On one extraordinary is R-Form, which utilizes even propping on 16 in. focuses, both all around. On the other is Agricola which calls for one plumb support each seven ft. on the inside of storm cellar dividers. A few developers discover they need more preparing for above-grade dividers than makers suggest. Following a couple of long stretches of involvement, a few developers have discovered that applying glue to the joints lessens the requirement for supporting. One developer utilizes around 48 containers of froth viable glue for a 1500 sq. ft. house.
Wind can cause issues. In the event that the site is blustery, additional propping might be required. Check for plumb for a few hours after the pour- – until the bao gia ep coc be tong 200×200 sets up. In the event that the divider moves a spot, you can utilize the supports to fix it before it sets up. In spite of the fact that corner propping is typically produced using 2x6s, one developer changed to point presses and saved time. Agricola offers their Green Blocks with 45-and 90-degree corner impedes that kill the requirement for corner supporting. A few of the square frameworks use handle like connections to help keep the dividers plumb. Sheet structures can be sewed together rapidly at butt joints by wrapping polypropylene bailing twine around the spacer tie plates on the structure’s external surface.
