The invention discloses a door stand column cover plate. The cover plate comprises a cover plate body, wherein an emergency unlocking opening is formed in a top end of one side of the cover plate body, an access hole is formed in a bottom end of one side of the cover plate body, diagonal reinforcing ribs are formed by compounding eight layers of plates, and innermost portions of the diagonal reinforcing ribs are two inner glass fiber layers with thickness of 0.2 mm; and the inner glass fiber layers are tightly attached and compositely connected. The cover plate is formed by compounding eight layers of boards, the boards are connected through inner and outer glass fibers, the interior is supported through four glass fiber and carbon fiber mixed layers, the total thickness of the board is 1.5 mm and is only one fourth of the thickness of a glass fiber reinforced plastic board under the condition that the same use requirement is met, and under the condition that the strength and stability are guaranteed, the weight of the plate is greatly reduced, the fireproof grade of the plate is further improved, safety is improved through the glassy carbon mixed multi-layer compounding mode, the plate is free of volatilization and pollution, the strength is guaranteed, and meanwhile production cost is reduced.
本发明公开了一种门立柱罩板,包括罩板主体,所述罩板主体一侧的顶端开设有紧急解锁口,且罩板主体一侧的底端开设有检修口,所述对角加强筋由八层板材复合而成,且对角加强筋最内部为两层0.2mm厚度的内玻璃纤维层,所述内玻璃纤维层之间进行紧贴复合连接。本发明通过八层板材复合而成,通过内外层的玻璃纤维进行连接,内部通过四层玻碳纤维混合层进行内部支撑,达到相同使用要求情况下,该板材总厚度为1.5mm,只有玻璃钢板材厚度的四分之一,在保证强度和稳定性的情况下,极大降低了板材本身的重量,且该玻碳混合多层的复合方式,更提高了该板材的防火等级,提高了安全性,且该板材无挥发、无污染,保证强度的同时,降低了生产成本。
