Graphical Construction Glossary >> Temporary Work. >> formwork >> Tilt Edge Form
The edge form here is made out of extruded aluminium and would come in 6M lengths. There are joiners available for extending them.
Tilt slabs are usually butted together with a 10mm gap between them for sealant. The joints are part of the overall design and either one or both faces is just painted in the finished job.
As a result they have to look good and the best way to do this is to chamfer off both edges. The chamfer takes away the need for tooling the edge while the concrete is being finished, it disguises any discrepancies between adjoining panels and it stops to a great extent the edges being chipped.
A chamfered edge can be done with a timber fillet nailed to timber edge forms, but they are hard to keep accurate.
The fillets in the photo above are to be used inside formply beam forms.
