DESCRIPTION OF THE FORMWORK
Formworks are customized to specific designs and are made of polystyrene foam coated with plastic resin. Arbloc creates each formwork so that it can be easily removed and reused.
The formwork can be placed on one or more levels of falsework, according to its sizes, shape and the building’s requirements.
Adhesive tape is applied on the joins in order to prevent the concrete from penetrating between the elements.
Polystyrene elements are applied around the perimeter to seal the gap between the formwork and the wall.
REMOVAL OF THE ARCHES
The lateral arches of the vault are removed by compressing the formwork towards the center. The middle arch-shaped space and the wooden boards glued to the base enable you to carry out this operation also with large size arches. The boards are drawn towards the middle space by using wires and twisting them. The force needed for detaching can vary from 100 to 300 kg.
REMOVAL OF THE VAULT
The elements of the vault are removed with a hydraulic jack. Constant pressure is exerted on the panel placed on the front of the casing. The pressure needed for removal can vary from around 100 to 500 kg per element.
