style="text-indent:25px">電纜橋架機統(tǒng)計量偏差大，通常是數(shù)量偏少。那么工程報價中如何比較準(zhǔn)確地統(tǒng)計電纜橋架的材料呢？一般而言，托架的直通部分可考慮1%～2%的裕量，彎通部分則直接統(tǒng)計數(shù)量。橋架全長除以平均立柱間距（戶外立柱跨距一般采取6m，室內(nèi)立柱跨距一般采取3m），得到立柱數(shù)，增加2%～4%裕量。而橋架全長除以支吊架平均間距，得到支吊架數(shù)，再考慮1%～2%裕量。至于支吊架的間距，戶內(nèi)直線段支吊架間距一般取1.5～3m，垂直安裝的支架間距不大于2m。非直線段的支吊架配置應(yīng)當(dāng)遵守規(guī)范規(guī)定：當(dāng)彎通彎曲半徑小于300mm時，應(yīng)在距非直線段與直線結(jié)合處300～600mm的直線段側(cè)設(shè)置一個支吊架；長寧區(qū)求購梯級式大跨距橋架</p></p><br
