Roof panel formed of two parallel plates delimiting a chamber between - plates

摘要

The panel (2) has superposed plates i.e. upper and lower plates (4, 5) respectively having opposite faces i.e. upper faces (4a, 5a) and lower faces (4b, 5b) delimited by sides (4a', 4b', 5a', 5b'). Two of the sides of the two opposite faces are connected by intercalary units defining an inter-plate chamber. The units have water and air sealed profiles (7) extending along the sides and including a flexible intercalary part (10) to allow the plates to occupy close and expanded positions in which the faces are spaced from each other, where a distance is greater than another distance. The panel is in square, rectangular, triangular, trapezoidal and hexagonal shape.
