電纜橋架已成為我們生活中常見的建筑材料，為響應環保政策，廠家現已開發出耐火電纜橋架、玻璃鋼耐火電纜橋架等新型優良產品。那么你知道耐火電纜橋架的主要組成部分及防火標準是什么嗎？

Cable tray has become a common building material in our life. In response to the national environmental protection policy, the manufacturer has developed new and excellent products such as fire-resistant cable tray and FRP fire-resistant cable tray. Do you know the main components and fire prevention standards of fire-resistant cable tray?

耐火電纜橋架的主要組成部分有哪些？

What are the main components of fire-resistant cable tray?

的山東電纜橋架廠家生產的產品的主要組成部分有：

The main components of products produced by professional Shandong cable tray manufacturers are:

1、梯形橋架，是由兩個縱向邊和幾個橫檔組成的梯形構件。2、打孔托盤由帶孔和邊的底板組成，或將整塊鋁合金板沖壓彎曲形成底部帶孔的凹槽部分。3、無孔托盤由底板和側面組成，或由整塊鋁合金板折彎而成的實底槽形部分。4、LQJ系列鋁合金防腐橋架等。

1. Trapezoidal bridge is a trapezoidal component composed of two longitudinal edges and several rungs. 2. The perforated tray is composed of a bottom plate with holes and edges, or the whole aluminum alloy plate is punched and bent to form a groove part with holes at the bottom. 3. The non perforated tray is composed of a bottom plate and sides, or a solid bottom groove shaped part formed by bending a whole aluminum alloy plate. 4. Lqj series aluminum alloy anti-corrosion bridge, etc.

立柱是支撐耐火電纜橋架的主要部件。橋梁的載荷通過支撐臂傳遞到立柱，因此立柱和支撐臂是索橋安裝的兩個主要組成部分。玻璃鋼防火電纜橋架的主要組成部分與普通防火電纜橋架相似，但材質不同。

The column is the main component supporting the fire-resistant cable tray. The load of the bridge is transmitted to the column through the support arm, so the column and the support arm are the two main components of the cable bridge installation. The main components of FRP fire-proof cable tray are similar to ordinary fire-proof cable tray, but the materials are different.

耐火電纜橋架的防火標準

Fire protection standard for fire-resistant cable tray
