电缆桥架的安装不要出现马虎的细节问题

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,并考虑引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 direction: Based on the building layout plan, combined with the installation of air conditioning and electrical pipelines, convenient maintenance, and the density of cable routing, determine the route of the cable tray. Indoor, it is best to install along the walls, columns, beams, and floors of the building. If it is necessary to use a comprehensive pipe gallery for installation, it should be installed parallel on one side or above the pipeline, and the down lead and branch lines should be avoided from crossing as much as possible. If there are no other pipe racks to borrow, it is necessary to set up (support) columns by oneself.

荷载计算:要计算电缆桥架主干线纵断面上单位长度的电缆重量。

Load calculation: To calculate the weight of the cable per unit length on the longitudinal section of the main cable tray.

3、确定桥架的宽度: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。还要确定支柱的长度、间距、桥架的宽度和层数。

3. Determine the width of the cable tray: Determine the model, specification, and arm length of the cable tray based on the number of laid cables, cable diameter, and cable spacing. Also determine the length, spacing, width, and number of layers of the support columns.

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。

4. Determine the installation method: Determine the fixing method of the bridge according to the setting conditions of the site, and choose the suspension type, vertical type, side wall type, or mixed type. The connectors and fasteners are generally supplied as a complete set.

5、如与电力电缆桥架合用时,应将电力电缆和弱电电缆各直一侧,中间采用隔板分隔。

5. When used in conjunction with power cable trays, the power cable and weak current cable should be separated by a partition on each side.

6、弱电电缆与其它低电压电缆合用桥架时,应严格执行选择具有外屏蔽层的弱电系统的弱电电缆,避免相互间的干扰。

6. When using a bridge with weak current cables and other low-voltage cables, strict selection of weak current cables with external shielding layers should be carried out to avoid mutual interference.

7、桥架支撑点,如立柱、托臂或非标准支、构架的间距、安装方式、型号规格、标高,可同意在平面上列表说明,也可分段标出用不同的剖面图、单线图或大样图表示。

7. The spacing, installation method, model specifications, and elevation of bridge support points, such as columns, brackets, or non-standard supports and frameworks, can be agreed to be listed on the plan, or marked in sections using different cross-sectional, single line, or detailed drawings.

8、电缆引下点位置及引下方式,一般而言,大批电缆引下可用垂直弯接板和垂直引上架,少量电缆引下可用导板或引管注明引下方式即可。

8. Generally speaking, for a large number of cables to be led down, a vertical bending plate and vertical lead up frame can be used, while for a small number of cables to be led down, a guide plate or pipe can be used to indicate the lead down method.

9、电缆桥架宜高出地面2.2米以上,桥架顶部距顶棚或其它障碍物不应小于0.3米,桥架宽度不宜小于0.1米,桥架内横断面的填充率不应超过百分之五十。

9. The cable tray should be 2.2 meters above the ground, and the distance from the top of the tray to the ceiling or other obstacles should not be less than 0.3 meters. The width of the tray should not be less than 0.1 meters, and the filling rate of the cross-section inside the tray should not exceed 50%.
