Document Type and Number:
Japanese Patent JP07054559
Kind Code:
A
Abstract:
PURPOSE: To provide a sheet shutter capable of easy machining and a low-cost partial repair, and having a high level of appearance and safety.
CONSTITUTION: The adjacent sections of sheets 10, 12 and 14 laid at upper and lower positions are superposed on top of one another, clamped with aluminum alloy reinforcing beam pairs 20 and 21, and tightened with bolts, thereby preparing one integrated piece of a sheet shutter. In this case, the sheet 14 is transparent and, therefore, functions effective at a work site particularly where safety must be visually confirmed.
