山东电缆桥架安装规范解析

  电缆桥架的安装需遵循严格规范,以保障其承载电缆的性和稳定性,同时为后续依据。安装规范贯穿于准备、施工及验收的全过程,每个环节都有明确要求。

  The installation of cable trays must follow strict specifications to ensure the safety and stability of the cables they carry, and to serve as a basis for future reference. Installation standards run through the entire process of preparation, construction, and acceptance, with clear requirements for each link.

  安装前的准备工作是规范执行的基础。需根据设计图纸核对现场环境,确认桥架的敷设路径、安装位置及标高是否与图纸一致,同时检查路径上是否存在障碍物,如管道、梁柱等,若有冲突需提前协调调整。其次,对进场的电缆桥架及附件(如支架、连接件、固定件等)进行外观检查,确保无变形、损坏、锈蚀等情况,材质和规格符合设计要求,必要时可核对产品相关合格证明文件。此外,准备好所需的安装工具,如电钻、扳手、水平仪等,确保工具完好且符合使用标准。

  The preparation work before installation is the foundation for standardized execution. Firstly, it is necessary to verify the on-site environment according to the design drawings, confirm whether the laying path, installation position, and elevation of the bridge are consistent with the drawings, and check whether there are obstacles on the path, such as pipelines, beams, and columns. If there are conflicts, they need to be coordinated and adjusted in advance. Secondly, conduct a visual inspection of the incoming cable trays and accessories (such as brackets, connectors, fixings, etc.) to ensure that there is no deformation, damage, rust, etc., and that the materials and specifications meet the design requirements. If necessary, check the relevant product qualification certificates. In addition, prepare the necessary installation tools such as drills, wrenches, level gauges, etc., to ensure that the tools are in good condition and meet safety usage standards.

  支架安装是桥架固定的关键环节,需严格遵循规范。支架的间距应根据桥架规格、承载重量及安装环境确定,通常在 1.5 米 3 米之间,间距过大可能导致桥架下垂变形。支架的固定方式需根据墙体、楼板等基层材质选择,如在混凝土基层上可采用膨胀螺栓固定,在钢结构上可采用焊接或螺栓连接,确保固定牢固可靠,避免松动。支架安装时需保持水平或垂直,同一方向的支架应在同一直线上,偏差不超过规定范围,以保证桥架安装后的平整度。

  The installation of brackets is a crucial step in fixing cable trays and must strictly comply with regulations. The spacing between brackets should be determined according to the specifications, load-bearing capacity, and installation environment of the bridge, usually between 1.5 meters and 3 meters. Excessive spacing may cause the bridge to sag and deform. The fixing method of the bracket needs to be selected according to the material of the base layer such as the wall and floor. For example, expansion bolts can be used to fix it on the concrete base layer, and welding or bolt connections can be used on the steel structure to ensure firm and reliable fixation and avoid loosening. When installing the bracket, it should be kept horizontal or vertical, and brackets in the same direction should be on the same straight line, with a deviation not exceeding the specified range, to ensure the flatness of the bridge after installation.

  桥架的组装与连接需符合规范要求。桥架之间的连接应采用专用连接件,连接时需紧密牢固,缝隙处可根据需要设置密封垫,防止灰尘、水汽进入。对于直线段桥架,其长度超过一定范围(通常为 30 米)时,应设置伸缩节,以应对温度变化引起的热胀冷缩,避免桥架变形。在转弯、分支处,需使用相应的弯通、三通等配件,确保桥架走向平滑过渡,转弯半径应满足电缆弯曲半径的要求,避免电缆因弯曲过度受损。

  The assembly and connection of the bridge frame must comply with the specifications. The connection between cable trays should use specialized connectors, which should be tightly and firmly connected. Sealing gaskets can be installed at the gaps as needed to prevent dust and moisture from entering. For straight cable trays, when their length exceeds a certain range (usually 30 meters), expansion joints should be installed to cope with thermal expansion and contraction caused by temperature changes and avoid deformation of the tray. At bends and branches, corresponding fittings such as bends and tees should be used to ensure a smooth transition in the direction of the bridge. The turning radius should meet the requirements of the cable bending radius to avoid damage to the cable due to excessive bending.

  桥架的敷设与固定也有明确规范。敷设时,桥架应与地面保持平行或垂直,排列整齐,层次分明,不同电压、不同用途的电缆应分槽敷设,若需共槽敷设,需采取隔离措施。桥架与支架之间的固定应牢固,每个桥架少应有两个固定点,防止桥架在受力时滑动。在穿越防火墙、楼板等部位时,需按规范要求进行防火封堵,使用防火材料填充缝隙,防止火灾蔓延。

  There are also clear specifications for the laying and fixing of cable trays. When laying, the cable tray should be kept parallel or perpendicular to the ground, arranged neatly and with clear layers. Cables of different voltages and purposes should be laid in separate slots. If they need to be laid in the same slot, isolation measures should be taken. The fixation between the bridge and the bracket should be firm, and each bridge should have at least two fixing points to prevent the bridge from sliding under stress. When passing through firewalls, floor slabs, and other areas, fireproof sealing should be carried out according to regulatory requirements, and fireproof materials should be used to fill gaps to prevent the spread of fire.

  安装后的检查验收是规范执行的收尾环节。检查桥架的整体平整度,用水平仪检测直线段是否水平,垂直度是否符合要求,偏差应控制在允许范围内。其次检查连接部位是否牢固,支架是否稳定,无松动、晃动现象。然后核对桥架的标高、位置及走向是否与设计一致,配件安装是否齐全。,清理安装过程中产生的杂物,确保桥架内部干净整洁,为后续电缆敷设创造良好条件。

  The inspection and acceptance after installation is the final stage of standardized execution. Firstly, check the overall flatness of the bridge frame, use a level to check whether the straight sections are horizontal and whether the verticality meets the requirements, and the deviation should be controlled within the allowable range. Next, check if the connection parts are secure, if the bracket is stable, and if there is no looseness or shaking. Then check whether the elevation, position, and direction of the bridge are consistent with the design, and whether the installation of accessories is complete. Finally, clean up any debris generated during the installation process to ensure that the interior of the cable tray is clean and tidy, creating favorable conditions for subsequent cable laying.
