在電網(wǎng)應(yīng)用中，電纜橋架發(fā)揮了什么作用與優(yōu)勢？電纜橋架也分為槽式，梯級式等，下面來講講山東橋架的制造與安裝留意事項(xiàng)。

What role and advantages does cable tray play in power grid application? The cable tray is also divided into trough type, ladder type, etc. Next, we will talk about the manufacturing and installation precautions of Shandong cable tray.

強(qiáng)、弱電線路應(yīng)分槽敷設(shè)，強(qiáng)、弱電線路不得與線槽直接接觸，強(qiáng)、弱電線路在分線盒（箱）交叉時(shí)須用金屬隔板隔開。各種配線在地線槽內(nèi)的只允許出口與分線盒連接。在施工和安裝地溝管時(shí)，要求將所有地溝管連成一個(gè)可靠的整體。

Strong and weak current lines shall be laid in separate slots. Strong and weak current lines shall not directly contact the trunking. Strong and weak current lines must be separated by metal partitions when crossing junction boxes (boxes). The outlet of various wiring in the ground wire slot is only allowed to be connected with the junction box. During construction and installation of trench pipes, it is required to connect all trench pipes into a reliable whole.

采用彈線法確定橋架的安裝位置，并對其進(jìn)行定位，作好標(biāo)記。豎井內(nèi)橋架的安裝基準(zhǔn)線應(yīng)先用懸吊法確定，隨時(shí)觀察預(yù)留孔，若不合適。應(yīng)及時(shí)調(diào)整，并進(jìn)行修補(bǔ)。

The installation position of the bridge shall be determined by snapping the line, and it shall be positioned and marked. The installation datum line of the cable tray in the shaft shall be determined by suspension method first, and the reserved holes shall be observed at any time, if not appropriate. It shall be adjusted and repaired in time.

按照施工圖的橋架規(guī)范和設(shè)計(jì)標(biāo)高對橋架進(jìn)行定位，然后制作支架需要根據(jù)測量尺寸，支架按工廠化生產(chǎn)。無頂棚的吊頂，沿梁底吊裝或靠墻支撐，有頂棚的，吊裝或靠墻支撐。

The bridge shall be positioned according to the bridge specification and design elevation in the construction drawing, and then the support shall be manufactured according to the measured size and factory production. The suspended ceiling without ceiling shall be hoisted along the beam bottom or supported against the wall, and the suspended ceiling with ceiling shall be hoisted or supported against the wall.

考慮到建筑美觀和便于維護(hù)，不掛頂?shù)墓部臻g組合結(jié)構(gòu)構(gòu)件，可采用靠墻安裝，屋內(nèi)下弦支撐安裝或柱子支撐安裝。靠墻的支座采用膨脹螺栓固定，支座間間隔不超過2米。

Considering the beauty of the building and the convenience of maintenance, the composite structural members of the public space without ceiling can be installed against the wall, supported by the lower chord of the house or supported by the column. The supports against the wall shall be fixed with expansion bolts, and the spacing between supports shall not exceed 2m.

對于橫跨建筑物變形縫、彎曲半徑大于300mm的橫截面積較大的橫截面積段，應(yīng)加裝吊具，吊具安裝時(shí)應(yīng)保證橋架水平或垂直度符合要求。

For the section with large cross sectional area crossing the deformation joint of the building and the bending radius greater than 300 mm, slings shall be installed. During the installation of slings, the levelness or perpendicularity of the bridge shall meet the requirements.

橋架的接地處理，可采用連接板作為跨接線，將其連在一起。在連接板的兩端安裝鍍鋅彈簧墊圈，用不少于4mm2的軟銅線跨越橋架，再將橋架與地線連接，形成電氣通道。橋梁架體和地線主干少應(yīng)有兩處連接。

For the grounding of the cable tray, the connecting plate can be used as the jumper to connect them together. Galvanized spring washers shall be installed at both ends of the connecting plate. Soft copper wires of not less than 4mm2 shall be used to cross the bridge, and then the bridge shall be connected with the ground wire to form an electrical channel. There shall be at least two connections between the bridge frame and the main grounding wire.

電纜橋架的制造與安裝留意事項(xiàng)就講解到這里了，您要注意對其進(jìn)行清潔以及定期的維護(hù)保養(yǎng)，更多相關(guān)事項(xiàng)就來我們網(wǎng)站http://m.ymmgjx.net咨詢吧！
