电缆桥架摆放不好会导致电缆扭曲变形、霉变、脱胶、油漆暴裂,或者鼓泡、退色,今天给大家介绍一下有关
山东桥架的保管与部件安装事项。
Improper placement of the cable tray will lead to distortion, mildew, degumming, paint cracking, blistering and discoloration of the cable. Today, I would like to introduce the storage and component installation of Shandong cable tray.
桥架的保管
Storage of bridge
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。
When the bridge cannot be installed temporarily, the storage place should be dry, covered and well ventilated, and the corrosion of acid, alkali, salt and other corrosive substances should be avoided. In the storage place, it must be stacked by classification, and it is not allowed to fall. The layers shall be separated by appropriate soft cushions to avoid high pressure, so as to prevent deformation and damage of anti-corrosion coating, which will affect the construction and bridge quality. In corrosive environment, anti-corrosion measures shall also be taken. Once deformation and damage of anti-corrosion coating are found, they shall be treated in time before storage.
桥架吊架安装
Installation of bridge hanger
采用通丝螺杆双杆式吊架安装方式。
The installation method of through screw double rod hanger is adopted.
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 horizontal bridge support adopts galvanized through wire screw as suspender and galvanized angle steel as cross arm. The support spacing is set at 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:
The through wire suspender shall be selected according to the width of the bridge, as shown below:
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,至少应满足底距吊顶50mm。
The vertical bridge support shall be made of profile steel, and the fixings shall be matched with the bridge. The support is fixed on the wall or floor and fixed with expansion bolts. When the vertical bridge passes through the floor, the shock-absorbing support shall be used where the anti vibration requirements need to be considered. When the plane bridge is installed, the distance between the bottom and the ceiling shall be at least 50mm.
桥架支、吊架的调整
Adjustment of bridge 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 the bridge, the position error of the supports and hangers of the bridge shall be strictly controlled. The supports and hangers of cable tray shall be installed firmly, horizontally and vertically. Support and hanger shall be fixed as required. The cross arms of 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 left and right deviation of bridge supports and hangers along the bridge direction shall not be greater than 10mm / m.
桥架与各种管道的小净距
Small clear distance between bridge and various pipes
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。
When the bridge is erected in parallel with the general process pipeline, the spacing shall not be less than 400mm; When the cable tray is erected in parallel with the heat pipe, the distance between the cable tray and the heat pipe shall not be less than 500mm if the heat pipe has an insulation layer, and not less than 1000mm if there is no 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。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,其间应采取有效的隔热措施;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。
When the bridge crosses with the general process pipeline, the clear distance shall not be less than 300mm. When the bridge is installed under the pipeline, it shall be protected with heat insulation board. The cable tray shall not be installed in parallel above the heat pipe. When it is unavoidable to install in parallel above the heat pipe, the spacing shall not be less than 1000mm, and effective thermal insulation measures shall be taken; When the cable tray crosses with the heat pipe, the crossing distance shall not be less than 500mm when the heat pipe has an insulation layer; when there is no insulation layer, the crossing distance shall not be less than 1000mm, and the cable tray shall be protected with a heat insulation plate (such as asbestos plate) at the intersection. The length of the heat insulation plate shall not be less than the outer diameter of the heat pipe insulation layer plus 2000mm.
In addition, before the bridge construction, it is necessary to optimize the layout of the comprehensive pipelines, maintain a reasonable spacing, reduce bending and collision, etc. if conditions permit, technology can be used for optimization and adjustment.
