槽式電纜橋架是現(xiàn)代電纜防護(hù)設(shè)備中為常用的一種托盤(pán)結(jié)構(gòu)橋架，槽式電纜橋架對(duì)于電纜傳輸完整信號(hào)和電纜分類管理都有很好的作用，槽式電纜橋架板材厚度在橋架相關(guān)相關(guān)標(biāo)準(zhǔn)例如/T 10216-2013中都有明確規(guī)定，不同材質(zhì)、不同寬度的濟(jì)南電纜橋架的厚度是不同的。相關(guān)知識(shí)點(diǎn)整理如下：

Trough type cable tray is a kind of tray structure tray commonly used in modern cable protection equipment. Trough type cable tray plays a very good role in complete signal transmission and cable classification management. The thickness of trough type cable tray is clearly specified in relevant standards of cable tray, such as /T 10216-2013. The thickness of Jinan cable tray with different materials and different widths is different. Relevant knowledge points are summarized as follows:

槽式電纜橋架改向彎通包括：垂直左上彎通、垂直右上彎通、垂直左下彎通、垂直右下彎通、垂直左上三通、垂直右上三通等。托盤(pán)重量和蓋板重量構(gòu)成了槽式槽式電纜橋架的主要重量，例如普通鍍鋅槽式電纜橋架規(guī)格100*50mm規(guī)格，托盤(pán)每米重量為3.67千克，蓋板每米的重量為2.20千克。

Channel type cable tray bend includes: vertical left upper bend, vertical right upper bend, vertical left lower bend, vertical right lower bend, vertical left upper tee, vertical right upper tee, etc. The weight of tray and cover plate constitute the main weight of trough type cable tray. For example, the size of ordinary galvanized trough type cable tray is 100 * 50mm, the weight of tray per meter is 3.67kg, and the weight of cover plate per meter is 2.20kg.

槽式電纜橋架吊架編寫(xiě)提料清單時(shí)應(yīng)填寫(xiě)：名稱+高度H+橫擔(dān)長(zhǎng)度L，例如：角鋼雙拉吊架，規(guī)格H=1500mm，L=1000mm（角鋼吊架默認(rèn)橫擔(dān)長(zhǎng)度=橋架寬度+200mm）。相關(guān)標(biāo)準(zhǔn)規(guī)定了槽式電纜橋架的耐火等級(jí)及其代號(hào)，耐火等級(jí)代號(hào)為N3，維持工作時(shí)間大于等于60分鐘。

When preparing the material withdrawal list for trough type cable tray hangers, the following shall be filled in: name+height H+cross arm length L, for example: angle steel double pull hanger, specification H=1500mm, L=1000mm (default cross arm length of angle steel hanger=tray width+200mm). The relevant standards specify the fire resistance rating and its code of the trough type cable tray. The fire resistance rating code is N3, and the maintenance time is no less than 60 minutes.

電纜橋架的常見(jiàn)高度有50mm、100mm、150mm、200mm等。電纜橋架的常見(jiàn)寬度有100mm、200mm、300mm、400mm、500mm、600mm等。在電纜橋架需要分叉敷設(shè)或者向上、向下方向延展時(shí)，可以設(shè)置彎通，因空間條件限制或有特殊要求，可以使用鉸連板。連接不同寬度或高度的兩段電纜橋架時(shí)，可以使用變寬或變高連接板。

The common heights of cable tray are 50mm, 100mm, 150mm, 200mm, etc. The common width of cable tray is 100mm, 200mm, 300mm, 400mm, 500mm, 600mm, etc. When the cable tray needs to be bifurcated or extended upward or downward, a bend can be set. Because of space conditions or special requirements, hinged plates can be used. When connecting two cable trays of different widths or heights, you can use a widening or heightening connection plate.

按照標(biāo)準(zhǔn)，連接板的厚度應(yīng)該與托盤(pán)和梯架的厚度保持一致，也可以選厚一個(gè)等級(jí)，蓋板的厚度可以比橋架板材的厚度低一個(gè)等級(jí)。規(guī)格600x100橋架，按照QB/T 1453-2003標(biāo)準(zhǔn)，橋架厚度應(yīng)為2.0mm，按照T/CECS 31-2017標(biāo)準(zhǔn)，橋架厚度應(yīng)為3.0mm。

According to the standard, the thickness of the connecting plate should be consistent with the thickness of the tray and ladder, or a grade of thickness can be selected, and the thickness of the cover plate can be one grade lower than the thickness of the tray plate. The specification of 600x100 cable tray shall be 2.0mm according to QB/T 1453-2003 standard, and 3.0mm according to T/CECS 31-2017 standard.
