<p><P>PROBLEM TO BE SOLVED: To provide a reed screen the clearance gap of which is adjustable depending on environmental changes such as solar altitude, amount of sunlight and force of wind, and also its clearance control system which can automatically control clearance gap of the reed screen. <P>SOLUTION: This reed screen composed of a plurality of reed bars knitted through a wire (12) is characterized by that a fixed bar (15) is fixedly coupled on top of the wire halfway, an operation bar (20) is mounted on bottom end of the wire, and a plurality of reed bars (11) are attached freely movable in a vertical direction along the wire (12) between the fixed bar (15) and the operation bar (20), while also being characterized by that any fixed bar (15) is mutually linked to each vertically adjacent reed bar (11) with a bar lashing (13) so that the space between these fixed bar and reed bar may not be widened to the level beyond the predefined gap, further the operation bar (20) has a tension device energized in the direction of pulling surplus length section on the wire by using a force above empty weight of the reed bar so as to shorten the wire length between the fixed bar (15) and this operation bar (20). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
