电缆桥架的计划和设备要求是什么?

电缆桥架的方案和设备要求)确定方向:根据施工方案,联系空调管道和电气管道的设置情况,方便维修,以及电缆布线的严密性来确定电缆桥架的佳路线。在室内,尽可能沿建筑物的墙壁、柱子、梁和地板,如何使用一般的管道廊,应在管道的一侧或以上平行设置,并考虑向下和支线,以尽量避免插入,如果没有其他管道框架可供借用,则有必要建立(分支)柱。
Determine the direction: according to the construction plan, contact the setting of air conditioning pipeline and electrical pipeline, convenient maintenance, and the tightness of cable wiring to determine the best route of cable tray. Indoor, as far as possible along the walls, columns, beams and floors of the building, how to use the general pipe gallery should be set in parallel on one side or above of the pipe, and consider the downward and branch lines to avoid insertion as far as possible. If there is no other pipe frame to borrow, it is necessary to establish (Branch) columns.
1.电缆桥架作为布线工程推广的支撑项目,没有专门的规范教学,厂家的规范程序缺乏通用性。因此,在方案选择过程中,应根据各系统弱电流电缆的类型和数量,合理选择合适的电桥。
1. As a supporting project of wiring engineering promotion, cable tray has no special standard teaching, and the manufacturer's standard procedure is lack of universality. Therefore, in the process of scheme selection, the appropriate bridge should be selected reasonably according to the type and number of weak current cables in each system.
主要内容如下:(1)根据施工方案确定电缆桥架的佳线路,联系空调管道和电力管道的设置条件,方便检修,确定电缆线路的密度。在室内,尽可能沿建筑物的墙壁、柱、梁和地板,如何使用一般的管道廊,应在管道一侧或以上平行设置,并考虑引向和支路,尽量避免插入,如果没有其他管架借来,就必须建立(分支)柱。
The main contents are as follows: (1) according to the construction scheme to determine the best line of cable tray, contact the air conditioning pipeline and power pipeline setting conditions, convenient maintenance, determine the density of cable line. Indoor, as far as possible along the wall, column, beam and floor of the building, how to use the general pipe gallery, should be set in parallel on one side or above the pipe, and consider the direction and branch, try to avoid insertion, if there is no other pipe frame borrowed, it must establish (Branch) column.
(3)确定桥梁宽度:根据索条数、索径和索间距确定电缆桥架的类型和规格、臂长、柱的长度和间距、桥面的宽度和层数。
(3) Determine the bridge width: according to the number of cables, cable diameter and cable spacing, determine the type and specification of cable bridge, arm length, column length and spacing, bridge deck width and number of layers.
(4)确定设备的措施:根据场所的设置条件,确定桥梁的固定方法,选择悬索式、立式、侧壁式或混合型,并普遍提供连接件和紧固件配合使用。此外,根据所述桥梁结构选择相应的盖板。
(4) Measures to determine the equipment: according to the setting conditions of the site, determine the fixing method of the bridge, select the suspension type, vertical type, side wall type or mixed type, and generally provide connectors and fasteners for use. In addition, the corresponding cover plate is selected according to the bridge structure.
3.在其他低压电缆桥接中使用弱电流电缆时,应严格选择具有外屏蔽层的弱电流电缆,以避免彼此间的干扰。
3. When using weak current cable in other low voltage cable bridging, the weak current cable with outer shielding layer should be strictly selected to avoid mutual interference.
静载是指敷设在电缆桥架中的电缆类型、根数、各外径/单位长度的重量,根据不同的电缆敷设路线分离列表计算。
Static load refers to the type, number and weight of each outer diameter / unit length of cables laid in the cable tray, which is calculated according to the separate list of different cable laying routes.
