作為一個項目，從經(jīng)濟利益的角度出發(fā)，在有限的成本資質(zhì)的前提下，選擇合適的材料一定是正確的做法。無論是哪種產(chǎn)品，只有保證質(zhì)量合格，才能充分發(fā)揮其使用效果和性。防火橋架也是如此，下面山東電纜橋架廠家來講講如何從3個方面來選擇防火橋架。

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、材料選擇。在眾多材料中，玻璃鋼的材料特點是質(zhì)量比較輕，僅為碳鋼的四分之一。它的耐腐蝕性和耐水性都非常好，適合在工廠使用，而且不燃、不燃燒的特點也讓它有比較長的使用壽命。通常，如果沒有意外事故，其使用壽命少為20年。此外，它的施工優(yōu)勢也非常明顯，組裝靈活、切割方便、安裝不著火是其獨特的特點。

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、選擇荷載等級，確定橋梁的寬度、層數(shù)、支撐點的類型和間距，以及每層鍍鋅橋梁上電纜的分布。在實際工程中，防火橋架尺寸的選擇存在較大偏差。有的比較緊張，有的比較放松。到底如何合理選擇防火橋架的尺寸，還是要參考的相關設計規(guī)定，特別是電纜的總截面積，截面積須準確計算托盤之間的比率。如果后面的規(guī)格有偏差，多半是這部分的比例不對。

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、防火等級的選擇，防火橋架在不同區(qū)域會有防火要求。因此，在一些特殊區(qū)域，需要選擇一些耐火、不燃的材料，形成封閉結(jié)構。并且還需要涂刷各種防火涂料出于保護目的在其表面。因此，在選擇材料時，如果在相同規(guī)格下，阻燃防火橋架一定是好的。雖然在上略貴，但其使用壽命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.

對防火橋架的不同要求對不同的材料選擇有更多的考慮，工程的設計應選擇何種材料，需要實地考察，并考慮周邊環(huán)境的綜合因素。更多相關內(nèi)容就來我們網(wǎng)站http://m.ymmgjx.net咨詢吧！
