作为一个项目，从经济利益的角度出发，在有限的成本资质的前提下，选择合适的材料一定是正确的做法。无论是哪种产品，只有保证质量合格，才能充分发挥其使用效果和安全性。防火桥架也是如此，下面 山东电缆桥架厂家来讲讲如何从3个方面来选择防火桥架。

As a project, from the perspective of economic benefits, under the premise of limited cost qualification, it must be the right way to select the appropriate materials. No matter what kind of product, only if the quality is qualified can its use effect and safety be fully played. The same is true for fireproof bridge. Next, Shandong cable bridge manufacturer will talk about how to select fireproof bridge from three aspects.

1、材料选择。在众多材料中，玻璃钢的材料特点是质量比较轻，仅为碳钢的四分之一。它的耐腐蚀性和耐水性都非常好，适合在工厂使用，而且不燃、不燃烧的特点也让它有比较长的使用寿命。通常，如果没有意外事故，其使用寿命至少为20年。此外，它的施工优势也非常明显，组装灵活、切割方便、安装不着火是其独特的特点。

1. Material selection. Among many materials, FRP is characterized by light weight, which is only one quarter of carbon steel. Its corrosion resistance and water resistance are very good, and it is suitable for use in factories, and its non-flammable and non-flammable characteristics also make it have a relatively long service life. Generally, if there is no accident, its service life is at least 20 years. In addition, its construction advantages are also very obvious. Its unique characteristics are flexible assembly, convenient cutting and non-igniting installation.

2、选择荷载等级，确定桥梁的宽度、层数、支撑点的类型和间距，以及每层镀锌桥梁上电缆的分布。在实际工程中，防火桥架尺寸的选择存在较大偏差。有的比较紧张，有的比较放松。到底如何合理选择防火桥架的尺寸，还是要参考的相关设计规定，特别是电缆的总截面积，截面积须准确计算托盘之间的比率。如果后面的规格有偏差，多半是这部分的比例不对。

2. Select the load level, determine the width of the bridge, the number of layers, the type and spacing of support points, and the distribution of cables on each layer of galvanized bridge. In the actual project, there is a large deviation in the selection of fire bridge size. Some are nervous and some are relaxed. In the end, how to reasonably select the size of the fireproof tray should refer to the relevant national design regulations, especially the total sectional area of the cable. The sectional area must accurately calculate the ratio between trays. If there is a deviation in the following specifications, the proportion of this part is probably wrong.

3、防火等级的选择，防火桥架在不同区域会有防火要求。因此，在一些特殊区域，需要选择一些耐火、不燃的材料，形成封闭结构。并且还需要涂刷各种防火涂料出于保护目的在其表面。因此，在选择材料时，如果在相同规格下，阻燃防火桥架一定是好的。虽然在价格上略贵，但其使用寿命至少是其他材料的五倍。

3. For the selection of fire rating, the fire bridge will have fire protection requirements in different areas. Therefore, in some special areas, it is necessary to select some fire-resistant and non-combustible materials to form a closed structure. In addition, it is also necessary to apply various fireproof coatings on its surface for the purpose of protection. Therefore, when selecting materials, the flame-retardant fireproof bridge must be good under the same specifications. Although slightly expensive, its service life is at least five times that of other materials.

对防火桥架的不同要求对不同的材料选择有更多的考虑，工程的设计应选择何种材料，需要实地考察，并考虑周边环境的综合因素。更多相关内容就来我们网站 //www.comprepyme.com咨询吧！
