电缆桥架分为槽式、托盘式和梯架式、镀锌桥架网格式等结构,由支架、托臂和安装附件等组成。建筑物内桥架可以独立架设, 也可以附设在各种建(构)筑物和管廊支架上,应体现结构简单,造型美观、配置灵活和维修方便等特点,全部零件均需进行镀锌处理,安装在建筑物外露天的桥架。

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.

桥架设计智能建筑的弱电系统,通常有多个信息监控和通信设施诸如楼宇自动化、办公自动化、通信自动化等相应的系统组成,除了建筑物本身的供电、供排水、空调、电梯和停车场等设施配置必要的信息监控外,还有安保自动化、消防自动化等若干个子系统,实现系统集成或部分系统集成。

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.

根据建筑主体的功能需求来确定其等级和内容,这些系统包括不同类别的电缆和导线,其中有些是属于有源缆线(电源电压一般为DC12/24/48V和AC220V), 由于建筑行业的不断的发展电缆桥架也在与时俱进并不断得到市场的认可和接受电缆桥架行业的国产化力度，产品选用优质冷轧钢板，得到广泛关注产品选用优质冷轧钢板，表面工艺有冷镀锌、热镀锌、静电喷涂、防火涂料、烤漆等。其中产品广泛用于石油化工，冶金，电力，学校通讯，高层建筑等领域，具有外形美观，耐腐蚀性强，通用性广泛，安装灵活方便，品种齐全等特点。

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.

电缆桥架作为承载各种电缆敷设的载体,从属于布线的需要,同样应遵循上述原则加以实施。由于建筑物内多种管线平行交叉,空间有限,特别是大型写字楼、金融商厦、酒店、场馆等建筑,信息点密集,缆线敷设除了采用楼板沟槽和墙内埋管方式外,在竖井和屋内天棚吊顶内广泛采用电缆桥架,提供不同走向的布线,弱电系统的各种缆线分类布放在桥架内,其路由选择和安装方式要根据走向的要求,并结合建筑结构和空调、电气等管线协商的位置加以确定,无源缆线不能与有源电缆并排铺设, 受条件所限铺放同一桥架内。

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.

其间必须采用金属隔板分设,引出的缆线尽量避免平面交叉,桥架穿越楼板,墙体或伸缩缝时,应该在建筑图上标出予留相应的空洞和位置,避免因遗漏等到施工时临时钻空,可能伤及土建结构。为了防止电磁辐射的干扰(EMC)，在桥架的设计中，应考虑桥架的封闭性。

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.
