Title:
GLASS PANEL SHUTTER
Document Type and Number:
Japanese Patent JP2626743
Kind Code:
B2
Abstract:
PURPOSE: To prevent a glass panel from being damaged due to the strain deformation of a casing, and thereby preventing a fire from being spread along with the deformation by preventing the bending of the casing from being disturbed by a lintel member when the metallic casing of each shutter panel is curved to the fire side due to thermal expansion.
CONSTITUTION: A plurality of shutter panels 2 where each glass panel 8 is enclosed by a metallic casing 4, is housed in an upper panel housing section 17 along side with a guide rail 3 when the panels are released. At least one lintel member 21 at the front and rear sides of a panel entrance section 19 for the panel housing section 17 is made to be capable of producing displacement in the direction that the lintel member is parted from the shutter panels 2.
