鋼結構工(gong)程開(kai)工(gong)前的(de)準備工(gong)作

鋼結構工程開(kai)工(gong)前的準備工(gong)作(zuo)主要有(you)：圖紙(zhi)審核、詳(xiang)圖設計(ji)、備料(liao)和核對、編制工(gong)藝(yi)流程、進行技術交底。以下是具體介紹(shao)。

1.圖紙審(shen)核。鋼結構(gou)(gou)工(gong)(gong)程在(zai)開(kai)工(gong)(gong)前應審(shen)核設計文件(jian)是否齊(qi)全；構(gou)(gou)件(jian)的(de)幾何尺寸是否正(zheng)確；節(jie)點是否清楚；構(gou)(gou)件(jian)的(de)數(shu)量是否符合(he)總數(shu)量，構(gou)(gou)件(jian)之(zhi)間(jian)的(de)連接(jie)形(xing)式是否合(he)理；加工(gong)(gong)符號、焊接(jie)符號是否齊(qi)全；圖紙的(de)標準是否符合(he)相關規定等。

2.詳圖(tu)(tu)設(she)(she)計(ji)。一般設(she)(she)計(ji)院提供的(de)鋼結(jie)構(gou)(gou)工(gong)(gong)程設(she)(she)計(ji)圖(tu)(tu)，不能直接用(yong)來加工(gong)(gong)制(zhi)作(zuo)鋼結(jie)構(gou)(gou)，施(shi)工(gong)(gong)單位在考(kao)慮加工(gong)(gong)工(gong)(gong)藝、公差配(pei)合、加工(gong)(gong)余(yu)量、焊接控制(zhi)等因素后，在原設(she)(she)計(ji)圖(tu)(tu)的(de)基(ji)礎上繪制(zhi)加工(gong)(gong)制(zhi)作(zuo)圖(tu)(tu)，又(you)稱施(shi)工(gong)(gong)詳圖(tu)(tu)。鋼結(jie)構(gou)(gou)工(gong)(gong)程的(de)加工(gong)(gong)制(zhi)作(zuo)圖(tu)(tu)是(shi)溝通設(she)(she)計(ji)人(ren)員及(ji)施(shi)工(gong)(gong)人(ren)員意圖(tu)(tu)的(de)詳圖(tu)(tu)，是(shi)實際(ji)尺寸劃線、剪(jian)切(qie)、坡口加工(gong)(gong)、制(zhi)孔、彎(wan)制(zhi)、拼裝、焊接、涂裝、產品檢查、堆放(fang)、發送等各(ge)項作(zuo)業的(de)指(zhi)示書。

3.備料(liao)(liao)和(he)核對(dui)。根據鋼結構(gou)工(gong)程圖紙(zhi)材(cai)料(liao)(liao)表計(ji)算(suan)出各種材(cai)質、規(gui)格的(de)(de)(de)材(cai)料(liao)(liao)凈(jing)用量(liang)，再加(jia)一(yi)定數量(liang)的(de)(de)(de)損耗提出材(cai)料(liao)(liao)預(yu)(yu)算(suan)計(ji)劃(hua)。鋼結構(gou)工(gong)程預(yu)(yu)算(suan)一(yi)般可按實際用量(liang)所(suo)需的(de)(de)(de)數值再增加(jia)10%進行提料(liao)(liao)和(he)備料(liao)(liao)。核對(dui)來料(liao)(liao)的(de)(de)(de)規(gui)格、尺寸、重量(liang)和(he)材(cai)質；材(cai)料(liao)(liao)代用必須經設計(ji)部門(men)同意，并進行相(xiang)應的(de)(de)(de)修改。

4.編(bian)(bian)(bian)制(zhi)工(gong)(gong)(gong)藝流程。編(bian)(bian)(bian)制(zhi)工(gong)(gong)(gong)藝流程的(de)原則是能以更快的(de)速度、更少的(de)勞(lao)動量和更低(di)的(de)費用(yong)，可靠地加工(gong)(gong)(gong)出符(fu)合設(she)計圖紙(zhi)要(yao)(yao)求(qiu)的(de)產(chan)品。鋼(gang)結構工(gong)(gong)(gong)程中工(gong)(gong)(gong)藝流程編(bian)(bian)(bian)制(zhi)的(de)內容包括：成品技術要(yao)(yao)求(qiu)；關鍵零件(jian)的(de)加工(gong)(gong)(gong)方法(fa)、精度要(yao)(yao)求(qiu)、檢查方法(fa)和檢查工(gong)(gong)(gong)具；主要(yao)(yao)構件(jian)的(de)工(gong)(gong)(gong)藝流程；工(gong)(gong)(gong)序質量標準、工(gong)(gong)(gong)藝措施（如組裝次序、焊接(jie)方法(fa)等(deng))；采(cai)用(yong)的(de)加工(gong)(gong)(gong)設(she)備(bei)和工(gong)(gong)(gong)藝設(she)備(bei)。

5.進行技術(shu)交(jiao)(jiao)底(di)(di)。技術(shu)交(jiao)(jiao)底(di)(di)按鋼結構工(gong)程的實施階(jie)段可分(fen)為開工(gong)前的技術(shu)交(jiao)(jiao)底(di)(di)和投料加工(gong)前進行的本廠施工(gong)人員技術(shu)交(jiao)(jiao)底(di)(di)兩個(ge)階(jie)段。
