    二、基本情況

    2、Basicinformation

    （1）荷載計(jì)算：計(jì)算索橋干線斷面上單位長(zhǎng)度的索重。

    (1)Loadcalculation:calculatethecableweightperunitlengthonthemainsectionofthecablebridge.

    （2）確定方向：根據(jù)建筑平面布置圖，結(jié)合空調(diào)管道、電氣管道的設(shè)置，維修方便，電纜線路密度，確定電纜橋架的更佳線路。在室內(nèi)，應(yīng)盡量沿建筑物的墻、柱、梁、樓板搭設(shè)。如果可以利用綜合管廊架設(shè)，應(yīng)在管的一側(cè)或上方平行架設(shè)，并考慮引下線和支線盡量避免交叉。如果沒有其他管架可供借用，則需自行設(shè)置（支撐）柱。

    (2)Determinethedirection:accordingtothelayoutplanofthebuilding,combinedwiththesettingofairconditioningpipesandelectricalpipes,convenientmaintenance,cablelinedensity,determinethebestlineofcablebridge.Indoors,itshouldbebuiltalongthewall,column,beamandfloorofthebuildingasfaraspossible.Iftheutilitytunnelcanbeusedforerection,itshallbeerectedinparallelononesideorabovethepipe,andthedownleadandbranchlineshallbeconsideredtoavoidcrossingasmuchaspossible.Ifthereisnootherpipesupportavailableforborrowing,itisnecessarytoset(support)thecolumnbyitself.

    （3）確定橋梁寬度：根據(jù)鋪設(shè)的電纜數(shù)量、電纜直徑和電纜間距，確定電纜橋架的型號(hào)和規(guī)格、支臂長(zhǎng)度、支柱長(zhǎng)度和間距、橋架的寬度和層數(shù)。

 (3)Determinethebridgewidth:accordingtothenumberofcableslaid,cablediameterandcablespacing,determinethemodelandspecificationofthecablebridge,thelengthofthearm,thelengthandspacingofthecolumn,thewidthandnumberoflayersofthebridge.

    （4）繪制電纜橋架的平面圖和剖面圖，繪制空間圖，列出部分零件的材料表。

    (4)Drawtheplanandsectionofthecabletray,drawthespacemap,andlistthematerialtableofsomeparts.

    （5）確定安裝方式：根據(jù)場(chǎng)地的設(shè)置條件確定橋梁的固定方式，選擇懸掛式、垂直式、側(cè)墻式或混合式。通常，連接器和緊固件一起提供。另外，根據(jù)橋梁結(jié)構(gòu)選擇相應(yīng)的蓋板。

 (5)Determinetheinstallationmode:determinethefixedmodeofthebridgeaccordingtothesitesettingconditions,andselectthesuspensiontype,verticaltype,sidewalltypeorhybridtype.Generally,connectorsaresuppliedwithfasteners.Inaddition,thecorrespondingcoverplateisselectedaccordingtothebridgestructure.

    三、當(dāng)弱電電纜與其它低壓電纜共用橋架時(shí)，應(yīng)嚴(yán)格選用具有外屏蔽層的弱電系統(tǒng)的弱電電纜，避免相互干擾。

    從整個(gè)行業(yè)的發(fā)展趨勢(shì)來看，盡管電纜橋架行業(yè)競(jìng)爭(zhēng)激烈，但濟(jì)南電纜橋架通過不斷的科技創(chuàng)新和技術(shù)攻關(guān)，已發(fā)展成為以服務(wù)為宗旨的國(guó)內(nèi)電纜橋架設(shè)備制造企業(yè)，并憑借在電纜橋架設(shè)備領(lǐng)域的造詣和巨大投入填補(bǔ)了電纜橋架行業(yè)的新的生產(chǎn)線空白。
