In our daily life, we can often see Shandong cable tray. Its appearance has brought us great convenience. However, after production, we need to pay attention to the installation and storage of some parts. So what exactly is it? Next, let our staff give you a brief introduction to their relevant knowledge points.

电缆桥架部件安装的注意事项：

Precautions for installation of cable tray components:

1、吊架安装：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。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。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，少应满足底距吊顶50mm。

1. Hanger installation: adopt threaded screw double rod hanger installation method. 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. 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. 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：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。

2. Adjustment of supports and hangers: During the installation of bridge, the position error of supports and hangers of bridge 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：桥架与一般工艺管道平行架设时，间距不应小于400mm；电缆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。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。电缆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，其间应采取隔热措施；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。

3. Small clear distance between cable tray and various pipes: when cable tray is erected in parallel with general process pipes, the distance shall not be less than 400mm; When the cable tray is erected in parallel with the thermal pipeline, the distance between them shall not be less than 500mm when the thermal pipeline has thermal insulation layer, and not less than 1000mm when there is no thermal insulation layer. 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 thermal insulation measures should be taken between them; 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.

桥架的保管：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。在保存场所一定要分类码放，不得摔打，层间应用适当软垫物隔开，避免高压，以防变形和防腐层损坏，影响施工和桥架质量。在有腐蚀的环境，还应有防腐蚀的措施，一经发现有变形和防腐层损坏，应及时处理后再存放。

Storage of cable tray: When the cable tray cannot be installed temporarily, its storage place should be dry, covered, well ventilated, and protected from corrosive substances such as acid, alkali and salt. In the storage place, it must be classified and stacked, and shall not be knocked. The layers shall be separated with appropriate soft cushion to avoid high pressure, so as to prevent deformation and damage of anti-corrosion coating, which will affect the construction and bridge quality. In the corrosive environment, there should also be anti-corrosion measures. Once deformation and anti-corrosion coating damage are found, they should be handled in time before storage.
