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.

一般來說，電纜質量太低。電纜橋架在使用過程中會膨脹和收縮。由于環境溫度的變化，例如鋼電纜橋架會隨著熱而膨脹，隨著冷而收縮。室外橋架的效果受溫度影響很大。因此，在使用過程中要注意溫度變化。

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.

山東電纜橋架

Shandong cable bridge

小編提醒您，在安裝電纜橋架之前，您不僅要滿足所需的荷載撓度，還要根據建筑物的結構特點、計算荷載、橋架的尺寸和撓度以及適當跨度的確定，考慮安裝的方便性。橋架安裝的準備工作是在兩個橋臺之間架設腳手架，并鋪設一個鞍座板作為氣動球閥的鋼橋安裝平臺。裝載機將用于從橋臺到兩側施工道路的場地平整。畫出堆場線，并標明橋架構件、配件和安裝工具的堆放位置。
 

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.

搖輥、平輥和座板的位置由測量放線確定。測量橋架線樁、搖樁、平樁和坐標板樁的標高。橋架的中間樁應測量到另一側的鼻架末端可以到達的距離。橋架架設所需的附件、架設工具和各種機械設備應做好充分準備，用5t自卸汽車分批運施工現場。可以考慮室外安裝工藝管道，但應注意電纜卷筒應安裝在易燃、易爆和低風險的一側。

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、外觀檢查山東電纜橋架門框，進入施工現場，應提交以下資料產品出廠合格證、省市質監站定期檢驗報告和相關技術鑒定文件，如電纜橋門框板厚度應符合相關要求。鍍鋅電纜橋架涂層表面應均勻，無過度燃燒、掛灰和局部不鍍鋅等缺陷。靜電噴涂應光滑、光滑、均勻、無皮、無氣泡，水泡橋架本身應光滑、無扭曲，內壁應光滑，橋架焊縫表面無毛刺應均勻，不得有漏焊、裂紋、燒穿等缺陷。

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.水平鋪設橋架時，電纜橋架的安裝位置和離地面的高度不應低于2.5m。當橋架多層鋪設時，橋架層間應留有一定的距離，以滿足散熱、維護和防干擾的需要。電纜橋架與各種管線平行敷設時，其凈距應符合相關規定。

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.支吊架的安裝，電纜橋架支吊架的質量應符合現行相關技術標準。電纜橋架水平敷設時，支撐跨度一般為1.5 ~ 3 m，垂直敷設時，固定間距不大于2 m，相鄰兩個橋架支撐臂之間的水平高差不大于10 mm，相鄰兩個橋架支撐臂垂直中間線的垂直偏差不大于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)確定方向：根據建筑布局，結合空調管道和電氣管道的設置條件，方便維護.

(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.材料統計

4. Material statistics

(1)橋架：各種類型和規格的橋架總長度分別計算。除了橋架的標準長度之外，還獲得了橋架的數量，并且允許增加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：如果采用統一的柱規格，可用橋架的總長度除以平均柱間距，得出柱數，余額增加2% ~ 4%。如果列規格不同，則需要單獨的統計數據。

(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：橋架總長度除以架平均間距，差額增加1% ~ 2%，即為總需求。

(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：將主要部分的數量乘以一定的比例，得到總數。

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