电缆桥架已成为我们生活中常见的建筑材料，为响应环保政策，厂家现已开发出耐火电缆桥架、玻璃钢耐火电缆桥架等新型优良产品。那么你知道耐火电缆桥架的主要组成部分及防火标准是什么吗？

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?

耐火电缆桥架的主要组成部分有哪些？

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

的 山东电缆桥架厂家生产的产品的主要组成部分有：

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

1、梯形桥架，是由两个纵向边和几个横档组成的梯形构件。2、打孔托盘由带孔和边的底板组成，或将整块铝合金板冲压弯曲形成底部带孔的凹槽部分。3、无孔托盘由底板和侧面组成，或由整块铝合金板折弯而成的实底槽形部分。4、LQJ系列铝合金防腐桥架等。

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.

立柱是支撑耐火电缆桥架的主要部件。桥梁的载荷通过支撑臂传递到立柱，因此立柱和支撑臂是索桥安装的两个主要组成部分。玻璃钢防火电缆桥架的主要组成部分与普通防火电缆桥架相似，但材质不同。

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.
