在日常的生活中我们经常可以见到桥架，其在生产完之后是有一些部件安装以及保管事项需要我们去注意的，那么 济南电缆桥架部件安装的注意事项是怎样的呢？

In our daily life, we can often see cable tray. After production, we need to pay attention to the installation and storage of some parts. What are the precautions for the installation of cable tray parts in Jinan?

1、吊架安装：

1. Hanger installation:

采用通丝螺杆双杆式吊架安装方式。水平桥架支架采用镀锌通丝螺杆作吊杆，镀锌角钢作横担，支架间距按2m设置，在桥架的转角处要设置支架，支架采用膨胀螺栓在楼板下固定。

The threaded screw double rod hanger is adopted for installation. The support of horizontal bridge adopts galvanized threaded rod as suspender and galvanized angle steel as cross arm. The spacing between supports is 2m. The support shall be set at the corner of the bridge. The support shall be fixed under the floor with expansion bolts.

通丝吊杆要根据桥架的宽度来选择，见下：竖向桥架支架采用型钢制作，固定件要与桥架配套。支架固定在墙体或楼板上，采用膨胀螺栓固定。

The wire hanger shall be selected according to the width of the cable tray, as shown below: the vertical cable tray support shall be made of section steel, and the fastener shall be matched with the cable tray. The support shall be fixed on the wall or floor and fixed with expansion bolts.

竖向桥架穿楼板时，需要考虑防震要求的地方，使用减震支架。平面桥架安装时近量往上抬，至少应满足底距吊顶50mm。

When the vertical cable tray passes through the floor, the shock absorption support shall be used where the seismic requirements need to be considered. When installing the plane bridge, lift it up to at least 50mm from the bottom to the ceiling.

2、支、吊架的调整：

2. Adjustment of supports and hangers:

桥架安装中，对桥架的支、吊架位置误差，应严格控制。电缆桥架支、吊架应安装牢固，横平竖直。支、吊架的固定方式应按要求进行。各支、吊架的同层横担应在同一水平面上，其高低偏差不应大于5mm/m；桥架支、吊架沿桥架走向左右的偏差不应大于10mm/m。

During the installation of cable tray, the position error of supports and hangers of cable tray shall be strictly controlled. The supports and hangers of cable tray shall be installed firmly, horizontally and vertically. The fixing method of supports and hangers shall be as required. The cross arms on the same layer of each support and hanger shall be on the same horizontal plane, and the height deviation shall not be greater than 5mm/m; The deviation of bridge supports and hangers from left to right along the bridge shall not be greater than 10mm/m.

3、桥架与各种管道的小净距：

3. Small clear distance between cable tray and various pipes:

桥架与一般工艺管道平行架设时，间距不应小于400mm；桥架与热力管道平行架设时，其间距当热力管道有保温层时不小于500mm，无保温层时，不应小于1000mm。

When the cable tray is erected in parallel with the general process pipe, the spacing shall not be less than 400mm; When the cable tray is erected in parallel with the heating pipeline, the distance between them shall not be less than 500mm if the heating pipeline has thermal insulation layer, and not less than 1000mm if there is no thermal insulation layer.

桥架与一般工艺管道交叉时，净距不应小于300mm，桥架在管道下方安装时，应使用隔热板保护。桥架不宜在热力管道的上方平行安装，当无法避免需在热力管道上方平行安装时，间距不应小于1000mm，其间应采取有效的隔热措施；

When the cable tray crosses the general process pipe, the clear distance shall not be less than 300mm. When the cable tray is installed under the pipe, it shall be protected by heat insulation board. The cable tray should not be installed in parallel above the thermal pipeline. When it is unavoidable to install it in parallel above the thermal pipeline, the spacing should not be less than 1000mm, and effective thermal insulation measures should be taken between them;

电缆桥架与热力管道交叉时，当热力管道有保温层时，交叉距离不应小于500mm，无保温层时，交叉距离不应小于1000mm，且有交叉处应用隔热板（例如石棉板）将电缆桥架保护起来，隔热板长度不应小于热力管保温层外径加2000mm。

When the cable tray crosses the thermal pipeline, the crossing distance shall not be less than 500mm when the thermal pipeline has thermal insulation layer, and 1000mm when there is no thermal insulation layer. The cable tray shall be protected by heat insulation board (such as asbestos board) at the intersection. The length of the heat insulation board shall not be less than the outer diameter of the thermal pipeline insulation layer plus 2000mm.

要注意桥架暂时不能安装时，其贮存场所宜干燥、有遮盖、有良好的通风环境，应避免酸、碱、盐等腐蚀性物质的侵蚀。更多使用注意事项可以来我们网站 //www.comprepyme.com进行咨询！

When the cable tray cannot be installed temporarily, its storage place should be dry, covered and well ventilated, and should avoid the corrosion of acid, alkali, salt and other corrosive substances. More precautions can be found on our website //www.comprepyme.com Consult!
