防火橋架在其表面添加了一層耐火材料，可有效防止火災(zāi)燒毀設(shè)備。一般用于敷設(shè)電纜等保護(hù)功能。那么你知道防火橋架和普通橋的區(qū)別嗎？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

function

防火橋架用于鋪設(shè)消防電梯、消防泵、消防電梯等需要防火的設(shè)備。普通橋架可以獨(dú)立架設(shè)，也可以在建筑物等支撐物上架設(shè)。

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.

防火橋架，表面磨砂，一般用于消防設(shè)備的配電線路，包括消防控制室、消防泵、消防電梯、防煙風(fēng)機(jī)和火災(zāi)自動(dòng)報(bào)警系統(tǒng)。除火災(zāi)自動(dòng)報(bào)警系統(tǒng)外，其他配電線路均可采用耐火電纜代替防火橋架架，也可采用普通橋架。

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.

適用條件

Applicable conditions

該防火橋架具有良好的防火效果和耐高溫性，應(yīng)用范圍廣泛。普通鍍鋅橋架一般情況下一般用于室內(nèi)環(huán)境，防水、防腐性能較差。

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.

結(jié)構(gòu)體

structural morphology

防火橋架手感粗糙，表面涂有防火漆。普通橋架由支架、吊架、支撐臂、安裝材料等結(jié)構(gòu)組成。

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.

防火橋架是在普通橋架外表面噴涂一層防火涂料，達(dá)到防火阻燃的效果。事實(shí)上，這座橋本身是不會(huì)著火的。著火的是電纜。防火涂料具有耐火阻燃的特點(diǎn)。

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.

普通山東橋架可以獨(dú)立敷設(shè)在建筑物內(nèi)，也可以敷設(shè)在各種建筑物（構(gòu)筑物）和管廊支架上。橋架的安裝應(yīng)遵循和體現(xiàn)結(jié)構(gòu)簡潔明了、外形美觀獨(dú)特、配置靈活、維修方便等特點(diǎn)。快速等特點(diǎn)，安裝在建筑物外露天的橋架及相關(guān)部件必須熱鍍鋅。

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.

橋架標(biāo)準(zhǔn)

Bridge standard

電纜起火后防火橋架的耐火時(shí)間分為>=60分鐘、>=45分鐘和>=30分鐘3個(gè)等級(jí)。地下車庫耐火時(shí)間要求>=60分鐘。對(duì)于橋架需要防火的部分，可在托盤和梯架上加入耐火或阻燃板和網(wǎng)狀材料，形成封閉或半封閉結(jié)構(gòu)。

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.

并且橋架表面涂有符合CECS2490《鋼結(jié)構(gòu)防火涂料應(yīng)用技術(shù)規(guī)范》的防火涂料。常見橋架要求在工程設(shè)計(jì)中，橋架布置應(yīng)根據(jù)經(jīng)濟(jì)合理性、技術(shù)可行性、運(yùn)行等因素綜合比較，確定好方案，充分滿足施工、安裝、維護(hù)和敷設(shè)電纜的要求。

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.
