电缆桥架的安装需要满足哪些要求

桥架的安装要求:
Installation requirements of bridge:
一、确定方向
1、 Determine direction
根据建筑平面布置图,结合空调管线和电气管线等设置情况、方便维修,以及电缆路由的疏密来确定电缆桥架的路线。在室内,尽可能沿建筑物的墙、柱、梁及楼板架设,如需利用综合管廊架设时,则应在管道一侧或上方平行架设。
According to the building layout plan, the route of cable tray is determined in combination with the setting of air conditioning pipeline and electrical pipeline, convenient maintenance and the density of cable route. Indoors, it shall be erected along the wall, column, beam and floor of the building as far as possible. If it is necessary to use the comprehensive pipe gallery, it shall be erected in parallel on one side or above the pipeline.
二、荷载计算
2、 Load calculation
计算电缆桥架主干线纵断面上单位长度的电缆重量。
Calculate the cable weight per unit length on the profile of the main line of the cable tray.
三、确定桥架的宽度
3、 Determines the width of the bridge
根据布放电缆条数、电缆直径及电缆的间距来确定电缆桥架的型号、规格,托臂的长度,支柱的长度、间距,桥架的宽度和层数。
According to the number of cables laid, cable diameter and cable spacing, determine the model and specification of cable tray, the length of supporting arm, the length and spacing of strut, the width and layers of cable tray.
四、确定安装方式
4、 Determine the installation method
根据场所的设置条件确定桥架的固定方式,选择悬吊式、直立式、侧壁式或是混合式,连接件和紧固件一般是配套供应的,此外,根据桥架结构选择相应的盖板。
The fixing mode of the bridge shall be determined according to the setting conditions of the site, and the suspension type, vertical type, side wall type or hybrid type shall be selected. The connectors and fasteners are generally supplied together. In addition, the corresponding cover plate shall be selected according to the bridge structure.
桥架可以独立架设, 也可以敷设在各种建(构)筑物和管廊支架上的连接方式。
The bridge can be erected independently or laid on various buildings (structures) and pipe gallery supports.
桥架分为槽式、托盘式和梯架式、网格式等结构,由支架、托臂和安装附件等组成。体现结构简单、造型美观、配置灵活和维修方便等特点,全部零件均需进行镀锌处理,安装在建筑物外露天的桥架。
The bridge is divided into trough type, tray type, ladder type, grid format and other structures, which is composed of support, bracket and installation accessories. It reflects the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized and installed in the open bridge outside the building.
如果是在邻近海边或属于腐蚀区,则材质需要具有防腐、耐潮气、附着力好, 耐冲击强度高的物性特点。由于环境温度变化,钢质电缆桥架会出现热胀冷缩的现象。
If it is near the sea or in a corrosive area, the material needs to have the physical characteristics of anti-corrosion, moisture resistance, good adhesion and high impact strength. Due to the change of ambient temperature, the steel cable tray will expand and contract.
电缆桥架的连接方式一般都是采用定制的连接片进行连接的,电缆桥架厂家在制作电缆桥架时会根据电缆桥架的型号规格,制作连接片的。
The connection mode of cable tray is generally connected with customized connecting pieces. When making cable tray, the cable tray manufacturer will make connecting pieces according to the model and specification of cable tray.
