In the process of using cable tray in Shandong, it is inevitable to encounter problems. The common problem is the short circuit of cable tray. Therefore, the following bridge manufacturer will tell you what preparation should be made to avoid short circuit of cable bridge: the common problem in the use of cable tray is short circuit, which may be caused by internal short circuit of cable or burning of cable.

一般来说，电缆质量太低。电缆桥架在使用过程中会膨胀和收缩。由于环境温度的变化，例如钢电缆桥架会随着热而膨胀，随着冷而收缩。室外桥架的效果受温度影响很大。因此，在使用过程中要注意温度变化。

Generally speaking, the cable quality is too low. Cable tray will expand and contract in the process of use. Due to the change of ambient temperature, for example, steel cable tray will expand with heat and shrink with cold. The effect of outdoor bridge is greatly affected by temperature. Therefore, attention should be paid to the temperature change in the process of use.

山东电缆桥架

Shandong cable bridge

小编提醒您，在安装电缆桥架之前，您不仅要满足所需的荷载挠度，还要根据建筑物的结构特点、计算荷载、桥架的尺寸和挠度以及适当跨度的确定，考虑安装的方便性。桥架安装的准备工作是在两个桥台之间架设脚手架，并铺设一个鞍座板作为气动球阀的钢桥安装平台。装载机将用于从桥台到两侧施工道路的场地平整。画出堆场线，并标明桥架构件、配件和安装工具的堆放位置。
 

Xiaobian reminds you that before installing cable tray, you should not only meet the required load deflection, but also consider the convenience of installation according to the structural characteristics of the building, the calculated load, the size and deflection of the bridge and the determination of appropriate span. The preparatory work for bridge installation is to erect scaffold between two abutments and lay a saddle plate as the steel bridge installation platform of pneumatic ball valve. The loader will be used for site leveling from abutment to construction road on both sides. Draw the yard line and mark the stacking position of bridge components, accessories and installation tools.

摇辊、平辊和座板的位置由测量放线确定。测量桥架线桩、摇桩、平桩和坐标板桩的标高。桥架的中间桩应测量到另一侧的鼻架末端可以到达的距离。桥架架设所需的附件、架设工具和各种机械设备应做好充分准备，用5t自卸汽车分批运施工现场。可以考虑室外安装工艺管道，但应注意电缆卷筒应安装在易燃、易爆和低风险的一侧。

The position of rocking roll, flat roller and seat plate is determined by surveying and setting out. Measure the elevation of bridge line pile, swing pile, flat pile and coordinate sheet pile. The distance that can be reached from the end of nose frame on the other side shall be measured at the middle pile of bridge. The accessories, erection tools and various mechanical equipment required for bridge erection shall be fully prepared and transported to the construction site by 5T dump truck in batches. Outdoor installation of process pipeline can be considered, but it should be noted that the cable drum should be installed on the flammable, explosive and low-risk side.

1、外观检查山东电缆桥架门框，进入施工现场，应提交以下资料产品出厂合格证、省市质监站定期检验报告和相关技术鉴定文件，如电缆桥门框板厚度应符合相关要求。镀锌电缆桥架涂层表面应均匀，无过度燃烧、挂灰和局部不镀锌等缺陷。静电喷涂应光滑、光滑、均匀、无皮、无气泡，水泡桥架本身应光滑、无扭曲，内壁应光滑，桥架焊缝表面无毛刺应均匀，不得有漏焊、裂纹、烧穿等缺陷。

1. Appearance inspection of Shandong cable bridge door frame, enter the construction site, should submit the following data, product factory certificate, provincial and Municipal Quality Supervision Station periodic inspection report and relevant technical appraisal documents, such as the thickness of cable bridge door frame plate should meet the relevant requirements. The coating surface of galvanized cable tray shall be uniform without excessive combustion, ash hanging and partial non galvanizing. The electrostatic spraying should be smooth, smooth, even, without skin and bubble. The blister bridge itself should be smooth and free from distortion. The inner wall should be smooth. The weld surface of the bridge should be uniform without burr. There should be no defects such as missed welding, crack and burn through.

2.水平铺设桥架时，电缆桥架的安装位置和离地面的高度不应低于2.5m。当桥架多层铺设时，桥架层间应留有一定的距离，以满足散热、维护和防干扰的需要。电缆桥架与各种管线平行敷设时，其净距应符合相关规定。

2. When the cable tray is laid horizontally, the installation position and height from the ground of the cable tray shall not be less than 2.5m. When the bridge is laid in multiple layers, there should be a certain distance between the bridge layers to meet the needs of heat dissipation, maintenance and anti-interference. When the cable tray is laid in parallel with various pipelines, the clear distance shall comply with relevant regulations.

3.支吊架的安装，电缆桥架支吊架的质量应符合现行相关技术标准。电缆桥架水平敷设时，支撑跨度一般为1.5 ~ 3 m，垂直敷设时，固定间距不大于2 m，相邻两个桥架支撑臂之间的水平高差不大于10 mm，相邻两个桥架支撑臂垂直中间线的垂直偏差不大于20m.

3. The installation of supports and hangers and the quality of supports and hangers of cable tray shall comply with the current relevant technical standards. When the cable tray is horizontally laid, the support span is generally 1.5 ~ 3 m; when it is vertically laid, the fixed spacing is not more than 2 m; the horizontal height difference between two adjacent bridge support arms is not more than 10 mm; and the vertical deviation of the vertical middle line of the two adjacent bridge support arms is not more than 20 m

(1)确定方向：根据建筑布局，结合空调管道和电气管道的设置条件，方便维护.

(1) Determine the direction: according to the building layout, combined with the setting conditions of air conditioning pipes and electrical pipes, easy to maintain

4.材料统计

4. Material statistics

(1)桥架：各种类型和规格的桥架总长度分别计算。除了桥架的标准长度之外，还获得了桥架的数量，并且允许增加1%-2%。

(1) Bridge: the total length of various types and specifications of bridge is calculated separately. In addition to the standard length of the bridge, the number of bridges is obtained, and an increase of 1% - 2% is allowed.

(2)立柱：如果采用统一的柱规格，可用桥架的总长度除以平均柱间距，得出柱数，余额增加2% ~ 4%。如果列规格不同，则需要单独的统计数据。

(2) Column: if a uniform column specification is adopted, the total length of the bridge can be divided by the average column spacing to get the number of columns, and the balance will be increased by 2% - 4%. If the column specifications are different, separate statistics are required.

(3)托臂：桥架总长度除以架平均间距，差额增加1% ~ 2%，即为总需求。

(3) Corbel: the total length of the bridge divided by the average spacing of the frame increases by 1% - 2%, which is the total demand.

(4)其它部件：将主要部分的数量乘以一定的比例，得到总数。

(4) Other parts: multiply the number of main parts by a certain proportion to get the total number.

小编认为山东电缆桥架需要按照相关规定寻找和使用，不同类型电缆桥架的适用范围不同，因此有必要根据自身要求寻找合适的桥架使用。不要盲目选择使用，这样不仅不能保证使用效果，还会缩短桥架的使用寿命。希望上述内容可以帮到大家，想要了解更多请点击官网：http://www.sdhangfeng.com

According to the author's opinion, Shandong cable tray needs to be searched and used according to relevant regulations. Different types of cable tray have different application scope, so it is necessary to find suitable cable tray according to its own requirements. Do not blindly choose to use, which not only can not guarantee the use effect, but also shorten the service life of the bridge. I hope the above can help you.
