PURPOSE: To reduce the thickness of a panel member composed of hinge-joined sheet members and to enable the member to maintain sufficient strength and rigidity, and then to make manufacture of the member easy and to be housed and transported, while the member is wound up. CONSTITUTION: Such a panel system as a temporary ceiling is constituted of a plurality of narrow and long panel members arranged in parallel. Each panel member is composed of three narrow and long slats 1, 2, and 3 which are arranged in parallel and joined with a flexible tape 4 along their adjacent edge sections. Although the panel member can be housed easily, the member turns into a coil-like state when the member is flattened, but for installation in a ceiling, the outside slats 2 and 3 are folded perpendicular to the central slat 1, so as to provide necessary rigidity. |
