半封锁式构造防火电缆桥架基材的组成
Fireproof bridge hot galvanized thick coating, corrosion resistance can be strong. Cold galvanizing more hot-dip galvanized layer of bright, but thinner, anti rust ability is weak. It is mainly composed of glass fiber reinforced material and inorganic adhesive composite fireproof board and metal skeleton compound and other fireproof base material.
外层加防火涂料，防火桥架遇火后不会熄灭，从而阻隔火势蔓延，具有极端良好的防火阻火效果，又具有耐火、耐油、耐腐蚀、、无污染，整体装置便当，构造合理，运用寿命长，并且美观，电缆装置在电缆桥架中，环境整洁，打扫便当。防火涂料有涂层薄、耐火极限高、粘接力强的特性。
The outer fire paint, fireproof cable tray in fire will not be extinguished, thus blocking the spread of fire, with the fire retardant effect of extreme good, but also has the fire resistance, oil resistance, corrosion resistance, non-toxic, no pollution, the whole device convenient, reasonable structure, long service life, beautiful appearance and cable in cable bridge, device, environment clean, easy to clean. Fire retardant coating properties of thin coating, high fire endurance, strong adhesion.
防火桥架，外表有磨砂感，普通运用在消防设各配电线路中，包括消防控制室、消防水泵、消防电梯、防排烟风机和火灾自动报警系统，除火灾自动报警系统外其他配电线路可采用耐火电缆，而无需采用防火桥架。
The fire tray, the appearance of a matte sense in common use in the distribution line in the fire, including the fire control room, fire pump, fire elevator, smoke exhaust fan and automatic fire alarm system, automatic fire alarm system in addition to other distribution lines can be used without the use of fire-resistant cable, fireproof cable tray.
防火桥架在公开车库中请求耐火时间大于1h。请求桥架防火的区段，可在托盘、梯架添加具有耐火或难燃性的板、网资料构成封锁或半封锁式构造。
Request fireproof bridge refractory time more than 1h in the open garage. In the section where the bridge is protected, a fireproof or nonflammable plate or mesh material can be added to the pallet and ladder to form a blockade or semi blockade structure.
