Recoverable casing for forming hollow space in peripheral wall of building to receive polystyrene block, has magnets to maintain casing against metal form panels, and closed cavity formed in rectangular parallelepiped hollow casing body

摘要

The casing (1) has magnets to maintain the casing against respective metallic form panels (12, 13), and a rectangular parallelepiped hollow casing body to define a hollow space, where a closed cavity is formed in the casing body. Each magnet comprises an active face to exert a magnetic attraction field, where the active face is visible from a casing body face applied against one of the form panels. An adjusting unit adjusts a position of the active face of each magnet along a direction orthogonal to the casing body face.
