Tilt-up technology utilizes innovative building techniques to reduce costs and construction time. With tilt-up, the walls are built horizontally on the structure’s floor slab or casting bed at the job site. The technique requires fewer skilled workers than masonry or precast panels, is faster to install and eliminates the high cost of transportation of precast panels or masonry blocks. After the foundation slab is poured, the wall panels are cast on the floor slab. Each panel is raised into place with a crane and secured by steel braces. The wall panels are connected to the steel structure at the footings, slab and roof line to complete the building process.
The Amvic EnerTILT tilt-up system was designed for commercial applications with need for exterior insulation on warehouses, cold storage facilities, schools, institutions or ‘big box’ retail units.
How it works: Floor Slab Casting Bed Construction
Before starting the process, it is important that the ground be thoroughly compacted and well supported. While the subfloor will be well compacted, it is still possible that floor settlement is likely to differ from that of the abutting wall and column foundations. It is necessary to isolate the floor slab from the walls and columns with isolation joints. These isolation joints will permit horizontal and vertical movement.
Step 1: Lay down forms.
Once the floor slab and edge forms are laid, the architects, engineers and contractors work closely together to plan the construction of the wall panels.
Step 2: Add Amvic Enertilt ICF’s.
Amvic EnerTILT panels are interlocked and assembled according to the construction drawings.
Step 3: Add Rebar Holders and add Rebar
Rebar chairs are inserted into the plastic web channels to reinforce the concrete.
Step 4: Place Lifting Inserts
Lifting insets are placed according to the size and weight of the panel.
Step 5: Pour Concrete
The concrete is poured, vibrated and allowed to cure. The concrete must reach a minimum compressive strength of 2500 psi (17.2 MPa).
Step 6: Life and install
Once in place, cables from the crane are attached to the rigging, the panel is raised and held in place with steel braces. This process is repeated until all the panels have been raised.
The EnerTILT system will significantly reduce both labor and material costs compared to other insulated tilt-up systems.
EnerTILT incorporates recycled plastic webs that provide a unique rebar chair anchoring system as well as strapping for drywall or exterior cladding.
There are 2 EnerTILT panels: the flat panel for walls up to 20 feet high and the ribbed system for walls higher than 20 feet. EnerTILT system can go as high as the wall design requires.
