而(er)在項(xiang)目(mu)執行階段采(cai)(cai)購部(bu)(bu)(bu)門老是和供(gong)貨(huo)(huo)商(shang)簽訂(ding)增(zeng)補合同，從而(er)導致總(zong)承包(bao)公司(si)利潤的(de)(de)降低。2）錯(cuo)項(xiang)。原因在于(yu)(yu)很多設計人(ren)員(yuan)對于(yu)(yu)一些概念不(bu)清，有的(de)(de)把彎通(tong)、支(zhi)(zhi)(zhi)吊(diao)架(jia)(jia)(jia)(jia)(jia)(jia)(jia)算作(zuo)附件(jian)(jian)(jian)，有的(de)(de)把蓋(gai)板(ban)(ban)(ban)當成(cheng)主材(cai)(cai)。實際上，電纜(lan)橋架(jia)(jia)(jia)(jia)(jia)(jia)(jia)的(de)(de)“托架(jia)(jia)(jia)(jia)(jia)(jia)(jia)”包(bao)括直(zhi)(zhi)通(tong)和彎通(tong)兩部(bu)(bu)(bu)分。電纜(lan)橋架(jia)(jia)(jia)(jia)(jia)(jia)(jia)的(de)(de)“附件(jian)(jian)(jian)”包(bao)括各種連接板(ban)(ban)(ban)、蓋(gai)板(ban)(ban)(ban)、隔板(ban)(ban)(ban)、壓板(ban)(ban)(ban)、終端板(ban)(ban)(ban)、引下(xia)件(jian)(jian)(jian)、緊固(gu)件(jian)(jian)(jian)等。附件(jian)(jian)(jian)在材(cai)(cai)料表中(zhong)(zhong)不(bu)開(kai)列，由供(gong)貨(huo)(huo)商(shang)隨貨(huo)(huo)配(pei)套供(gong)應(ying)(ying)，成(cheng)本打(da)入托架(jia)(jia)(jia)(jia)(jia)(jia)(jia)的(de)(de)單價(jia)部(bu)(bu)(bu)分，工程(cheng)中(zhong)(zhong)不(bu)需要供(gong)貨(huo)(huo)商(shang)單獨報(bao)價(jia)。而(er)“支(zhi)(zhi)(zhi)吊(diao)架(jia)(jia)(jia)(jia)(jia)(jia)(jia)”包(bao)括托臂、立(li)柱(zhu)(zhu)、吊(diao)架(jia)(jia)(jia)(jia)(jia)(jia)(jia)等，需要單獨開(kai)列，工程(cheng)中(zhong)(zhong)供(gong)貨(huo)(huo)商(shang)需要單獨報(bao)價(jia)。3）統計量(liang)偏(pian)差大，通(tong)常(chang)是數量(liang)偏(pian)少。那么工程(cheng)報(bao)價(jia)中(zhong)(zhong)如何比較準確地統計電纜(lan)橋架(jia)(jia)(jia)(jia)(jia)(jia)(jia)的(de)(de)材(cai)(cai)料呢？一般而(er)言(yan)，托架(jia)(jia)(jia)(jia)(jia)(jia)(jia)的(de)(de)直(zhi)(zhi)通(tong)部(bu)(bu)(bu)分可考(kao)慮(lv)1%～2%的(de)(de)裕(yu)量(liang)，彎通(tong)部(bu)(bu)(bu)分則直(zhi)(zhi)接統計數量(liang)。橋架(jia)(jia)(jia)(jia)(jia)(jia)(jia)全長(chang)除(chu)以(yi)平(ping)均立(li)柱(zhu)(zhu)間距(ju)（戶外(wai)立(li)柱(zhu)(zhu)跨(kua)距(ju)一般采(cai)(cai)取(qu)6m，室內(nei)立(li)柱(zhu)(zhu)跨(kua)距(ju)一般采(cai)(cai)取(qu)3m），得到(dao)立(li)柱(zhu)(zhu)數，增(zeng)加2%～4%裕(yu)量(liang)。而(er)橋架(jia)(jia)(jia)(jia)(jia)(jia)(jia)全長(chang)除(chu)以(yi)支(zhi)(zhi)(zhi)吊(diao)架(jia)(jia)(jia)(jia)(jia)(jia)(jia)平(ping)均間距(ju)，得到(dao)支(zhi)(zhi)(zhi)吊(diao)架(jia)(jia)(jia)(jia)(jia)(jia)(jia)數，再(zai)考(kao)慮(lv)1%～2%裕(yu)量(liang)。至于(yu)(yu)支(zhi)(zhi)(zhi)吊(diao)架(jia)(jia)(jia)(jia)(jia)(jia)(jia)的(de)(de)間距(ju)，戶內(nei)直(zhi)(zhi)線(xian)(xian)段支(zhi)(zhi)(zhi)吊(diao)架(jia)(jia)(jia)(jia)(jia)(jia)(jia)間距(ju)一般取(qu)～3m，垂直(zhi)(zhi)安裝(zhuang)的(de)(de)支(zhi)(zhi)(zhi)架(jia)(jia)(jia)(jia)(jia)(jia)(jia)間距(ju)不(bu)大于(yu)(yu)2m。非直(zhi)(zhi)線(xian)(xian)段的(de)(de)支(zhi)(zhi)(zhi)吊(diao)架(jia)(jia)(jia)(jia)(jia)(jia)(jia)配(pei)置應(ying)(ying)當遵(zun)守規范規定：當彎通(tong)彎曲半徑小(xiao)于(yu)(yu)300mm時，應(ying)(ying)在距(ju)非直(zhi)(zhi)線(xian)(xian)段與(yu)直(zhi)(zhi)線(xian)(xian)結(jie)合處300～600mm的(de)(de)直(zhi)(zhi)線(xian)(xian)段側設置一個支(zhi)(zhi)(zhi)吊(diao)架(jia)(jia)(jia)(jia)(jia)(jia)(jia)。中(zhong)(zhong)山托盤(pan)式橋架(jia)(jia)(jia)(jia)(jia)(jia)(jia)制作(zuo)
