半封闭式电缆桥架的整体耐火性能

  1)济南电缆桥架在有防火要求的区段内,可在电缆梯架、托盘内添加具有耐火或难燃性能的板、网等材料构成封闭或半封闭式结构,并采取在桥架及其支吊架表面涂刷防火涂层等措施,其整体耐火性能应满足国家有关规范或标准的要求。
  1) Ji'nan cable tray in a fire in the section, the cable tray ladder, added with fire or flame retardant properties of the plate, net material enclosed or semi enclosed structure, and take on the bridge and the support surface coated with fireproof coating and other measures, the resistance should meet the national requirements relevant rules or standards.
  2)电缆桥架、线槽及其支吊架使用在有腐蚀性环境中,应采用耐腐蚀的刚性材料制造,或采取防腐蚀处理,防腐蚀处理方式应满足工程环境和耐久性的要求。
  2) cable bridge, line slot and support hangers are used in corrosive environment. They should be made of corrosion-resistant rigid materials or take anti-corrosion treatment. The way of anticorrosion treatment should meet the requirements of engineering environment and durability.
  3)各种组件及支吊架在满足相应荷载的条件下,其规格尺寸应与托盘、梯架的直线段、弯通系列相匹配.
  3) the specifications and sizes of various components and support frames should be matched with the line and bend series of the tray, the ladder frame and the staircase.

  4)在工程防火要求较高的场所,不宜采用铝合金电缆桥架。
  4) aluminum alloy cable bridge should not be used in places with higher fire protection requirements.
  5)对于跨距大于6m 的钢制电缆桥架和跨距大于2m 或承载要求大于荷载等级D级的铝合金电缆桥架,应按工程条件进行强度、刚度及稳定性的计算或试验验证。
  5) for the steel cable bridge with span greater than 6m and the span length greater than 2m or the load bearing requirement is greater than the load grade D grade aluminum alloy cable tray, the strength, stiffness and stability of the aluminum alloy cable bridge should be calculated or verified according to the engineering conditions.
  6)电缆梯架宽度和高度的选择应符合填充率的要求,电缆的梯架的填充率在一般情况下,电力电缆可取40%~50%,控制电缆可取50%~70%,且宜预留10%~25%工程发展裕量。
  6) the selection of the width and height of the cable ladder should meet the requirement of filling rate. In the general case, the power cable should be 40% to 50%, and the control cable should be 50% to 70%, and the 10% to 25% engineering development allowance should be reserved.
  7)在选择电缆梯架的荷载等级时,电缆桥架的工作均布荷载不应大于所选电缆桥架荷载等级的额定均布荷载,如果电缆桥架的支吊架的实际跨距不等于2m 时,则 工作均布荷载应满足要求。
  7) when selecting the load level of cable ladder rack, the uniformly distributed load of the cable tray should not be greater than the rated load of the selected cable bridge load grade. If the actual span of the support and hanger of the cable bridge is not equal to 2m, the uniform load should meet the requirements.
