Description

   Fire-resistant metal rolling door sheet structure   

The invention relates to a fire-resistant metal roll-up door sheet structure. A first heat-shielding sheet and a second heat-insulation sheet are respectively arranged on both sides of the fire-proof metal roll-up door sheet, thereby blocking the inside and outside of the fire-proof metal roll-up door sheet. The heat conduction between them, thus improving their fire prevention effect.

Generally speaking, most metal roll doors have no fire-proof structure design; therefore, as soon as a fire occurs, thin metal roll doors cannot resist the high heat flowing from the fire source. For this reason, the industry has launched various metal rolls with fire insulation functions. Door slice structure. For related technologies, please refer to pre-patent cases such as I 321188, I 352772, M342408, M424391, M444423, M447922, M468559, and M480586.

Although the above-mentioned pre-patent case is advertised as having a fire prevention function, there is a major deficiency in the structure, mainly because the metal roll of the roll door and the heat shield are made of metal materials, and the two are directly connected and contacted. Although a heat-shielding material is provided inside the heat shield, as long as one side is heated, the other side will also heat up due to the heat conduction of the metal. In this case, the high heat of the fire field (about 950 ~ 1,000 ° C) It will also quickly transfer high heat from the side facing the fire source along the outer edge of the metal to the other side facing away from the fire source, which greatly reduces the fire prevention function of the metal fire shutter.

For this reason, the inventor has previously proposed the M530344 patent case, which can effectively solve the aforementioned problems, but this case will necessarily use a heat shield and fill it with a heat-resistant material inside. Great room for improvement.
