桥架又叫做电缆桥架,是建筑电气工程中用于线缆的敷设,主要作用是保护、管理、支撑线缆或光纤。那么梯级式桥架安装是怎样的呢?下面济南电缆桥架厂家为您解答。
Cable tray, also called cable tray, is used for cable laying in building electrical engineering. Its main function is to protect, manage and support cables or optical fibers. So what is the installation of step bridge? Next, Jinan cable bridge manufacturer will answer for you.
1)电缆桥架及线槽敷设走向应短捷,并应尽量沿墙、沿柱或沿梁敷设。
1) The cable tray and trunking shall be laid along the wall, column or beam as soon as possible.
2)依据电缆桥架及线槽敷设走向,向土建、结构提出预留墙洞、楼板洞及吊架装置时,所需预埋钢板方位及荷载。而且应与工艺、水暖及动力相和谐。
2) According to the laying trend of cable tray and trunking, the orientation and load of the embedded steel plate required for the reserved wall hole, floor hole and hanger device are proposed to the civil engineering and structural disciplines. It should also be in harmony with technology, plumbing and power.
3)地上内暗装金属线槽布线,在设计时应与土建密切配合,以便依据不同的结构型式和修建布局,合理断定线路途径和设备选型。
3) The concealed metal trunking wiring on the ground shall be designed in close cooperation with the civil engineering discipline, so as to reasonably determine the route and equipment selection according to different structural types and construction layout.
4)不同电压、不同用处的电缆不宜敷设在同一层电缆桥架内:
4) Cables with different voltages and different uses should not be laid in the same layer of cable tray:
1kV以上和1kV及以下的电缆;
Cables above 1kV and below 1kV;
同一途径向一级负荷供电的双回路电缆;
Double-circuit cables supplying power to primary load in the same way;
应急照明和其他照明的电缆;
Cables for emergency lighting and other lighting;
电力、操控和电信电缆。若不同等级的电缆敷设在同一电缆桥架时,中心应添加隔板阻隔。
Power, control and telecommunication cables. If cables of different grades are laid on the same cable tray, a partition shall be added in the center to block them.
5)在工程条件下装置或检修不需考虑附加会集荷载时,电缆梯架、托盘的作业均布荷载按电缆自重均匀分布核算。
5) When additional concentrated load is not required for installation or maintenance under engineering conditions, the operation uniform load of cable ladder and tray shall be calculated according to the uniform distribution of cable dead weight.
6)电缆桥架不宜与下列管道平行敷设,当无法防止时,电缆桥架的方位应契合下列规则,或采纳相应防护办法。
6) The cable tray should not be laid in parallel with the following pipes. When it cannot be prevented, the orientation of the cable tray should conform to the following rules or adopt corresponding protective measures.

电缆桥架应在具有腐蚀性液体管道上方。
The cable tray shall be above the pipeline with corrosive liquid.
电缆桥架应在热力管道下方。
The cable tray shall be under the heating pipe.
易燃易爆气体比空气重时,电缆桥架应在管道上方。
When flammable and explosive gases are heavier than air, the cable tray shall be above the pipe.
易燃易爆气体比空气轻时,电缆桥架应在管道下方。
When the flammable and explosive gas is lighter than air, the cable bridge shall be under the pipe.
7)电缆桥架与管道之间小间隔见相关标准。
7) See relevant standards for small spacing between cable tray and pipeline.
8)归纳布线电缆与邻近可能发生高电平电磁搅扰的电动机、电力变压器等电气设备之间应坚持必要的距离。归纳布线电缆与电力电缆的距离应契合GB/T50311-2000标准11.0.2条的规则。
8) Necessary distance shall be maintained between inductive wiring cables and electrical equipment such as motors, power transformers, etc. that may cause high level electromagnetic disturbance. The distance between inductive wiring cable and power cable shall conform to the rules of Article 11.0.2 of GB/T50311-2000 standard.
9)墙上敷设的归纳布线电缆、光缆及管线与其它管线的距离应契合GB/T50311-2000标准11.0.2条的规则。
9) The distance between inductive cabling cables, optical cables and pipelines laid on the wall and other pipelines shall conform to the rules of Article 11.0.2 of GB/T50311-2000 standard.
10)电缆桥架水平敷设时,宜按荷载曲线选取佳跨距进行支撑,跨距一般为1.5~3.0m。笔直敷设时,其固定距离不宜大于2m。
10) When the cable tray is laid horizontally, the best span should be selected according to the load curve for support, and the span is generally 1.5~3.0m. When laying straight, the fixed distance should not be more than 2m.
