橋(qiao)架的(de)選擇：當鋼制直(zhi)線(xian)段長(chang)度超(chao)過(guo)30m，鋁合(he)金電(dian)纜(lan)(lan)橋(qiao)架超(chao)過(guo)15m時．或(huo)當電(dian)纜(lan)(lan)橋(qiao)架經(jing)過(guo)建(jian)筑伸縮(沉降(jiang))縫時應留有(you)O-30mm補償余量．其連(lian)接宜采用伸縮連(lian)接板(ban)。合(he)理(li)選定橋(qiao)架：確(que)定方向：根(gen)據建(jian)筑平面(mian)布(bu)置圖，結合(he)空調管線(xian)和電(dian)氣(qi)管線(xian)等設(she)置情(qing)況、方便維修，以及(ji)電(dian)纜(lan)(lan)路(lu)(lu)由的(de)疏密來確(que)定電(dian)纜(lan)(lan)橋(qiao)架的(de)路(lu)(lu)線(xian)。電(dian)纜(lan)(lan)橋(qiao)架和我們(men)(men)的(de)生活息(xi)息(xi)相關，幾乎用得到(dao)電(dian)的(de)地方都會有(you)電(dian)纜(lan)(lan)橋(qiao)架，因為電(dian)纜(lan)(lan)橋(qiao)架保護著(zhu)我們(men)(men)的(de)用電(dian)安全。

噴(pen)塑橋架(jia)的介紹。噴(pen)塑電(dian)(dian)纜橋架(jia)是將(jiang)塑料(liao)粉(fen)末噴(pen)涂(tu)在電(dian)(dian)纜橋架(jia)上的一種外(wai)表處置辦法(fa)。不(bu)需稀料(liao)，施(shi)工(gong)(gong)(gong)對環(huan)境無(wu)污染，對人(ren)體(ti)無(wu)；涂(tu)層(ceng)外(wai)觀質量優良，噴(pen)塑橋架(jia)，附著力及機械強(qiang)(qiang)度強(qiang)(qiang)；噴(pen)涂(tu)施(shi)工(gong)(gong)(gong)固(gu)化時間(jian)短；涂(tu)層(ceng)耐腐(fu)耐磨才(cai)能高出許多；不(bu)需底漆；施(shi)工(gong)(gong)(gong)簡潔，對工(gong)(gong)(gong)人(ren)技能需求低；本錢低于噴(pen)漆技術(shu)；有(you)些施(shi)工(gong)(gong)(gong)場(chang)合現已明確提出有(you)必(bi)要(yao)運用(yong)靜電(dian)(dian)噴(pen)塑技術(shu)處置；靜電(dian)(dian)噴(pen)粉(fen)噴(pen)涂(tu)進程中不(bu)會呈現噴(pen)漆技術(shu)中常見的流動表象(xiang)。

橋(qiao)架(jia)的選擇：在工程設(she)計(ji)中，橋(qiao)架(jia)的布(bu)置(zhi)應根據經濟合理(li)性、技術可行(xing)性、運行(xing)安全性等因(yin)素綜合比較，以確(que)定方(fang)案(an)，還(huan)要充(chong)分滿足施工安裝、維(wei)護檢修(xiu)及電(dian)(dian)(dian)纜敷設(she)的要求(qiu)。合理(li)選定橋(qiao)架(jia)：確(que)定方(fang)向：根據建筑平面(mian)布(bu)置(zhi)圖，結合空調管線(xian)和(he)電(dian)(dian)(dian)氣管線(xian)等設(she)置(zhi)情況、方(fang)便維(wei)修(xiu)，以及電(dian)(dian)(dian)纜路由的疏密來確(que)定電(dian)(dian)(dian)纜橋(qiao)架(jia)的路線(xian)。用途：地下室停車場(chang)(chang)、廠房輸電(dian)(dian)(dian)、個性酒(jiu)店，大(da)型商(shang)場(chang)(chang)（用不(bu)同顏色去搭(da)配(pei)項(xiang)目(mu)建觀）等等...
