橋架一般主要是在建筑室內及高壓電的配電工程進行使用的，可以應用于不同的環境。橋架產品的安置要點關乎安全要重視，所以下面來看看要點內容有什么。

The bridge is generally used in indoor buildings and high-voltage power distribution projects, which can be applied to different environments. The key points of bridge product placement are related to safety and should be paid attention to, so let's see what the key points are.

1、在有防火要求的路段，索梯和橋架可加裝耐火或阻燃板、網等材料，形成封閉或半封閉結構，橋架及其支吊架可以使用。表面涂有防火涂料等措施。

1. In the sections with fire prevention requirements, the cable ladder and bridge can be equipped with fire-resistant or flame-retardant plates, nets and other materials to form a closed or semi closed structure. The bridge and its supports and hangers can be used. The surface is coated with fireproof coating and other measures.

2、鋼索橋架直線段長度超過30m，鋁合金橋架超過15m，或橋梁通過建筑物伸縮（沉降）縫時，應預留0-30mm的補償余量，連接宜采用伸縮連接板。

2. When the straight section length of steel cable bridge exceeds 30m, aluminum alloy bridge exceeds 15m, or the bridge passes through the expansion (settlement) joint of the building, a compensation allowance of 0-30mm shall be reserved, and the expansion connecting plate should be used for connection.

3、在工程設計中，橋架布置應根據經濟合理性、技術可行性、運行安全等因素綜合比較，確定方案，充分滿足施工、安裝、維修的要求，和電纜鋪設。

3. In the engineering design, the bridge layout shall be determined according to the comprehensive comparison of economic rationality, technical feasibility, operation safety and other factors, so as to fully meet the requirements of construction, installation and maintenance and cable laying.

4、在腐蝕性環境中使用時，山東電纜橋架、線槽及其支吊架應采用耐腐蝕的剛性材料，或進行防腐處理。防腐處理方法應符合工程環境和耐久性要求。對于耐腐蝕或清潔度要求較高的場所，應選用鋁合金電纜橋架。

4. When used in corrosive environment, Shandong cable tray, trunking and its supports and hangers shall be made of corrosion-resistant rigid materials or subject to anti-corrosion treatment. The anti-corrosion treatment method shall meet the requirements of engineering environment and durability. For places with high corrosion resistance or cleanliness requirements, aluminum alloy cable tray shall be selected.、

5、山東橋架的寬度和高度的選擇應滿足填充率的要求。一般來說，梯架和托盤中的電纜填充率應為電力電纜的40-50%，控制電纜的50-50%。70,10-25%應預留給項目開發。

5. The width and height of Shandong bridge shall meet the requirements of filling rate. In general, the cable filling rate in ladders and trays shall be 40-50% of power cables and 50-50% of control cables. 70,10-25% should be reserved for project development.

6、需要屏蔽電磁干擾的電纜線路。或者當有環境要求以防止外部影響時，例如室外陽光、油、腐蝕性液體和易燃粉塵。應選擇無孔橋架式電纜橋架。

6. Cable lines that need to be shielded from electromagnetic interference. Or when there are environmental requirements to prevent external effects, such as outdoor sunlight, oil, corrosive liquids and flammable dust. Non perforated bridge type cable tray shall be selected.

7、要求電纜的厚度至少與板厚相同或低一級。還應對電纜橋架的外觀和形狀進行檢修，以確保電纜橋架平整、清潔、無損壞。橋的厚度也要用的檢測儀器檢查，橋的表面光澤度不得低于規定的60%。此外，表面還應有防霧保護層等。

7. The thickness of the cable is required to be at least the same as or one level lower than the plate thickness. The appearance and shape of the cable tray shall also be overhauled to ensure that the cable tray is flat, clean and free from damage. The thickness of the bridge shall not be less than 60% of the specified surface gloss. In addition, the surface shall also have anti fog protective layer, etc.

8、在容易積塵的地方，應用蓋板蓋住橋架；在公共通道或室外過馬路段，應在底橋上加墊板或無孔托盤。

8. Cover the bridge with cover plate in the place where dust is easy to accumulate; In the public passage or outdoor road crossing section, the base plate or non perforated tray shall be added on the bottom bridge.

以上就是山東橋架的安置需要考慮到的一些要點，在使用電纜橋架時要格外注意細節，這樣才能有利于橋架的后期使用，更多信息的獲取就來網站m.ymmgjx.net關注吧。
