防火桥架在其表面添加了一层耐火材料，可有效防止火灾烧毁设备。一般用于敷设电缆等保护功能。那么你知道防火桥架和普通桥的区别吗？在下面找到。

A layer of refractory is added to the surface of the fire-proof bridge, which can effectively prevent fire from burning the equipment. It is generally used for cable laying and other protection functions. Do you know the difference between fire bridge and ordinary bridge? Found below.

功能

防火桥架用于铺设消防电梯、消防泵、消防电梯等需要防火的设备。普通桥架可以独立架设，也可以在建筑物等支撑物上架设。

The fire-proof bridge is used to lay the fire elevator, fire pump, fire elevator and other equipment that need fire protection. Ordinary bridge can be erected independently or on supports such as buildings.

防火桥架，表面磨砂，一般用于消防设备的配电线路，包括消防控制室、消防泵、消防电梯、防烟风机和火灾自动报警系统。除火灾自动报警系统外，其他配电线路均可采用耐火电缆代替防火桥架架，也可采用普通桥架。

The fire-proof bridge, with frosted surface, is generally used for the distribution line of fire-fighting equipment, including fire control room, fire pump, fire elevator, smoke fan and automatic fire alarm system. In addition to the automatic fire alarm system, other distribution lines can use fire-resistant cables to replace the fire-resistant bridge frame, and can also use ordinary bridges.

适用条件

Applicable conditions

该防火桥架具有良好的防火效果和耐高温性，应用范围广泛。普通镀锌桥架一般情况下一般用于室内环境，防水、防腐性能较差。

The fire-proof bridge has good fire-proof effect and high temperature resistance, and has a wide range of applications. Ordinary galvanized cable tray is generally used in indoor environment, with poor waterproof and anti-corrosion performance.

结构体

structural morphology

防火桥架手感粗糙，表面涂有防火漆。普通桥架由支架、吊架、支撑臂、安装材料等结构组成。

The fire-proof bridge has a rough feel and its surface is coated with fire-proof paint. The common bridge is composed of supports, hangers, support arms, installation materials and other structures.

防火桥架是在普通桥架外表面喷涂一层防火涂料，达到防火阻燃的效果。事实上，这座桥本身是绝对不会着火的。唯一着火的是电缆。防火涂料具有耐火阻燃的特点。

The fireproof bridge is sprayed with a layer of fireproof paint on the external surface of the ordinary bridge to achieve the effect of fire prevention and flame retardance. In fact, the bridge itself will never catch fire. The only thing that caught fire was the cable. Fire retardant coating has the characteristics of fire resistance and flame retardancy.

普通 山东桥架可以独立敷设在建筑物内，也可以敷设在各种建筑物（构筑物）和管廊支架上。桥架的安装应遵循和体现结构简洁明了、外形美观独特、配置灵活、维修方便等特点。快速等特点，安装在建筑物外露天的桥架及相关部件必须热镀锌。

Ordinary Shandong bridge can be laid in buildings independently, or on various buildings (structures) and pipe gallery supports. The installation of the bridge shall follow and reflect the characteristics of simple and clear structure, beautiful and unique appearance, flexible configuration and convenient maintenance. The cable tray and related parts installed outside the building in the open air must be hot-dip galvanized.

桥架标准

Bridge standard

电缆起火后防火桥架的耐火时间分为>=60分钟、>=45分钟和>=30分钟3个等级。地下车库耐火时间要求>=60分钟。对于桥架需要防火的部分，可在托盘和梯架上加入耐火或阻燃板和网状材料，形成封闭或半封闭结构。

The fire resistance time of fire-proof cable tray after cable fire is divided into three grades: > =60 minutes, > =45 minutes and > =30 minutes. The fire resistance time of underground garage shall be > =60 minutes. For the part of the bridge that needs fire protection, fire-resistant or flame-retardant plates and reticulated materials can be added to the tray and ladder to form a closed or semi closed structure.

并且桥架表面涂有符合CECS2490《钢结构防火涂料应用技术规范》的防火涂料。常见桥架要求在工程设计中，桥架布置应根据经济合理性、技术可行性、运行安全等因素综合比较，确定好方案，充分满足施工、安装、维护和敷设电缆的要求。

In addition, the cable tray surface is coated with fire retardant coating in accordance with cecs2490 technical code for application of fire retardant coating for steel structures. Common bridge requirements in the engineering design, the bridge layout shall be determined according to the comprehensive comparison of economic rationality, technical feasibility, operation safety and other factors to fully meet the requirements of construction, installation, maintenance and cable laying.
