Fire-proof bridge is suitable for laying power cables below 10KV, control cables, lighting wiring and other indoor and outdoor overhead cable trenches and tunnels.

　　防火桥架主要由玻璃纤维增强材料和无机黏合剂复合的防火板与金属骨架复合以及其他的防火基材组成。外层加防火涂料，防火桥架遇火后不会燃烧，从而阻隔火势蔓延，具有极其良好的防火阻火效果，又具有耐火、耐油、耐腐蚀、、无污染，整体安装方便，结构合理，使用寿命长，并且美观，电缆安装在电缆桥架中，环境整洁，清扫方便。防火涂料有涂层薄、耐火极限高、粘接力强的特点。

　　Fire-proof bridge is mainly composed of glass fiber reinforced material and inorganic binder composite fire-proof board, metal skeleton composite and other fire-proof substrates. Fire-proof coating is added to the outer layer to prevent the fire-proof bridge from burning after fire, thus preventing the spread of fire. It has excellent fire-proof and fire-proof effect, fire-proof, oil-proof, corrosion-resistant, non-toxic, pollution-free, convenient overall installation, reasonable structure, long service life, and beautiful. Cables are installed in the cable bridge and environment. Clean and easy to clean. Fire retardant coatings have the characteristics of thin coating, high fire resistance limit and strong adhesion.

　　防火桥架，表面有磨砂感，一般运用在消防设备配电线路中，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。防火桥架在地下车库中要求耐火时间大于1h。要求桥架防火的区段，可在托盘、梯架添加具有耐火或难燃性的板、网材料构成封闭或半封闭式结构，并在桥架表面涂刷符合CECS 24; 90《钢结构防火涂料应用技术规范》的防火涂层，其整体耐火性应符合有关规范、标准的要求。

　　Fire-proof bridge with frosted surface is generally used in distribution lines of fire-fighting equipment, including fire control room, fire pump, fire elevator, smoke-proof fan and fire automatic alarm system. Fire-proof cable can be used in other distribution lines besides fire automatic alarm system, without using fire-proof bridge. Fire-proof bridge in underground garage requires fire-resistant time greater than 1 hour. In the section requiring fire protection of bridge frame, the closed or semi-closed structure can be constructed by adding fire-resistant or flame-retardant plate and net materials to pallets and ladders, and the fire-resistant coatings conforming to CECS 24 can be painted on the surface of bridge frame. 90 The fire-resistant coatings of "Technical Specification for Application of Fire-retardant Coatings for Steel Structures" should conform to the requirements of relevant national standards and standards.
