PURPOSE: A shutter box for a heat insulation fireproof shutter is provided to suppress the spread of heat and flame due to a fire by effectively isolating the shutter box from heat. CONSTITUTION: A shutter box for a heat insulation fireproof shutter comprises a main frame(110), an interception unit(140), an intermediate frame(120), an outer frame(130). The main frame is filled with heat insulation elements and is formed with a guide groove in the entrance thereof. The interception unit is inserted into the guide groove of the main frame and is elastically installed. The heat insulation element is inserted into the intermediate frame. A space is formed between the heat insulation element and main frame. The outer frame surrounds the intermediate frame while maintaining a predetermined spacing from the intermediate frame. |
