电缆桥架的选择要注意什么?

(1)确定方向: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适合路由。在室内,尽可能沿建筑物的墙、柱、梁及楼板架设,如许利用综合管廊架设时,则应在管道一侧或上方平行架设并考虑下线和分支线尽量避免交叉,如无其它管架借用,则需自设立(支)柱。
(1) Determine the direction: determine the suitable route of cable tray according to the building layout plan, combined with the setting of air conditioning pipeline and electrical pipeline, convenient maintenance, and the density of cable route. In the room, it should be erected along the walls, columns, beams and floors of the building as much as possible. If it is possible to use the integrated pipe gallery for erection, it should be erected parallel on one side or above the pipe and consider that the downline and branch line should avoid crossing as much as possible. If there is no other pipe rack to borrow, it is necessary to set up (support) columns by itself.
(2)荷载计算:计算电缆桥架主干线纵断面上单位长度的电缆重量。
(2) Load calculation: calculate the weight of cable per unit length on the profile of cable bridge trunk line.
(3)确定桥架的宽度:根据布放电缆条数、电缆直径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

(3) Determine the width of the cable tray: determine the model and specification of the cable tray, the length of the bracket, the length of the support, the width and the number of layers of the cable tray according to the number of cables laid and the cable diameter and the spacing of the cable
(4)确定安装方式: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折相应的盖板。
(4) Determine the installation mode: determine the fixed mode of the bridge according to the setting conditions of the site. Select the suspension type, vertical type, side wall type or hybrid type. The connectors and fasteners are generally supplied in a complete set. In addition, select the corresponding cover plate according to the bridge structure.
(5)绘出电缆桥架平、剖面图,局部部位还应绘出空间图,开列材料表。
(5) Draw the plane and section drawings of the cable tray, and the space map and material list for local parts.
