電纜橋架分為槽式、托盤式和梯架式、鍍鋅橋架網(wǎng)格式等結(jié)構(gòu),由支架、托臂和安裝附件等組成。建筑物內(nèi)橋架可以獨立架設(shè), 也可以附設(shè)在各種建(構(gòu))筑物和管廊支架上,應(yīng)體現(xiàn)結(jié)構(gòu)簡單,造型美觀、配置靈活和維修方便等特點,全部零件均需進行鍍鋅處理,安裝在建筑物外露天的橋架。

Cable trays are divided into slot type, tray type, ladder type, galvanized cable tray mesh format, and other structures, which are composed of brackets, brackets, and installation accessories. The bridge in the building can be erected independently or attached to various buildings (structures) and pipe rack supports. It should reflect the characteristics of simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts need to be galvanized and installed in the outdoor bridge outside the building.

橋架設(shè)計智能建筑的弱電系統(tǒng),通常有多個信息監(jiān)控和通信設(shè)施諸如樓宇自動化、辦公自動化、通信自動化等相應(yīng)的系統(tǒng)組成,除了建筑物本身的供電、供排水、空調(diào)、電梯和停車場等設(shè)施配置必要的信息監(jiān)控外,還有安保自動化、消防自動化等若干個子系統(tǒng),實現(xiàn)系統(tǒng)集成或部分系統(tǒng)集成。

Bridge design The weak current system of an intelligent building usually consists of multiple information monitoring and communication facilities such as building automation, office automation, communication automation, and other corresponding systems. In addition to the necessary information monitoring for the power supply, water supply and drainage, air conditioning, elevators, parking lots, and other facilities of the building itself, there are several subsystems such as security automation, fire automation, and other systems to achieve system integration or partial system integration.

根據(jù)建筑主體的功能需求來確定其等級和內(nèi)容,這些系統(tǒng)包括不同類別的電纜和導(dǎo)線,其中有些是屬于有源纜線(電源電壓一般為DC12/24/48V和AC220V), 由于建筑行業(yè)的不斷的發(fā)展電纜橋架也在與時俱進并不斷得到市場的認可和接受電纜橋架行業(yè)的國產(chǎn)化力度，產(chǎn)品選用冷軋鋼板，得到廣泛關(guān)注產(chǎn)品選用冷軋鋼板，表面工藝有冷鍍鋅、熱鍍鋅、靜電噴涂、防火涂料、烤漆等。其中產(chǎn)品廣泛用于石油化工，冶金，電力，學(xué)校通訊，高層建筑等領(lǐng)域，具有外形美觀，耐腐蝕性強，通用性廣泛，安裝靈活方便，品種齊全等特點。

The level and content of the building body are determined based on its functional requirements. These systems include different types of cables and wires, some of which are active cables (power supply voltages are generally DC12/24/48V and AC220V). Due to the continuous development of the construction industry, cable trays are also advancing with the times and gaining market recognition and acceptance of the localization efforts of the cable tray industry. The products are made of high-quality cold-rolled steel plates, Products that have received widespread attention are high-quality cold-rolled steel plates, with surface processes such as cold galvanizing, hot galvanizing, electrostatic spraying, fireproof coating, baking paint, etc. The products are widely used in fields such as petrochemical, metallurgy, electric power, school communication, high-rise buildings, etc., with beautiful appearance, strong corrosion resistance, wide versatility, flexible and convenient installation, and a complete range of features.

電纜橋架作為承載各種電纜敷設(shè)的載體,從屬于布線的需要,同樣應(yīng)遵循上述原則加以實施。由于建筑物內(nèi)多種管線平行交叉,空間有限,特別是大型寫字樓、金融商廈、酒店、場館等建筑,信息點密集,纜線敷設(shè)除了采用樓板溝槽和墻內(nèi)埋管方式外,在豎井和屋內(nèi)天棚吊頂內(nèi)廣泛采用電纜橋架,提供不同走向的布線,弱電系統(tǒng)的各種纜線分類布放在橋架內(nèi),其路由選擇和安裝方式要根據(jù)走向的要求,并結(jié)合建筑結(jié)構(gòu)和空調(diào)、電氣等管線協(xié)商的位置加以確定,無源纜線不能與有源電纜并排鋪設(shè), 受條件所限鋪放同一橋架內(nèi)。

As a carrier for carrying various types of cable laying, cable trays are subordinate to the needs of wiring, and should also be implemented in accordance with the above principles. Due to the parallel intersection of multiple pipelines in buildings and limited space, especially in large office buildings, financial malls, hotels, stadiums, and other buildings, where information points are dense, cable trays are widely used in vertical shafts and indoor ceilings, in addition to the use of floor trenches and embedded pipes, to provide wiring in different directions. Various cables for weak current systems are classified and placed within the tray, and their routing and installation methods should be based on the requirements of the direction, The location shall be determined based on the building structure and the negotiated location of air conditioning, electrical, and other pipelines. Passive cables cannot be laid side by side with active cables, and are limited by conditions to be laid within the same bridge.

其間必須采用金屬隔板分設(shè),引出的纜線盡量避免平面交叉,橋架穿越樓板,墻體或伸縮縫時,應(yīng)該在建筑圖上標出予留相應(yīng)的空洞和位置,避免因遺漏等到施工時臨時鉆空,可能傷及土建結(jié)構(gòu)。為了防止電磁輻射的干擾(EMC)，在橋架的設(shè)計中，應(yīng)考慮橋架的封閉性。

Metal partitions must be used to separate them, and the outgoing cables should avoid plane crossing as much as possible. When the bridge passes through floors, walls, or expansion joints, corresponding holes and positions should be marked on the architectural drawing to avoid temporary drilling due to omission during construction, which may damage the civil structure. In order to prevent electromagnetic radiation interference (EMC), the closure of the bridge should be considered in the design of the bridge.
