（3）審核施工單位(wei)報審的(de)(de)(de)(de)原(yuan)材(cai)料(liao)、成品的(de)(de)(de)(de)質量保證資料(liao)、原(yuan)材(cai)料(liao)的(de)(de)(de)(de)合(he)格證書，構件出廠合(he)格證，規(gui)范(fan)規(gui)定原(yuan)材(cai)料(liao)有6種情(qing)況之一，須進行復驗時(shi)，監理應參加見證取樣。鋼板(ban)(ban)的(de)(de)(de)(de)厚度、型鋼的(de)(de)(de)(de)規(gui)格、尺(chi)寸(cun)(cun)是影響承載力的(de)(de)(de)(de)主要(yao)因(yin)素，進場驗收時(shi)，應重點抽驗鋼板(ban)(ban)厚度和型鋼規(gui)格、尺(chi)寸(cun)(cun)。

（4）焊(han)接材料對(dui)焊(han)接質量影響重(zhong)大，采用的焊(han)接材料應(ying)按(an)設(she)計要(yao)求(qiu)選(xuan)用，并應(ying)符合國家現行(xing)標準。對(dui)于外觀不符合要(yao)求(qiu)的焊(han)接材料，不應(ying)再工程(cheng)中使用。

（5）涂料的進(jin)場驗(yan)收(shou)除(chu)檢驗(yan)資料文件外，還(huan)(huan)要開桶抽查，除(chu)檢查涂料結(jie)皮、結(jie)塊、凝膠等現象外，還(huan)(huan)要與質量證明文件對照涂料的型(xing)號(hao)、名稱(cheng)、顏色及(ji)有效期等。

（6）為保證工(gong)(gong)程焊(han)接(jie)(jie)(jie)質量，必須在構(gou)件(jian)制作和結(jie)構(gou)安裝施工(gong)(gong)焊(han)接(jie)(jie)(jie)前進(jin)行焊(han)接(jie)(jie)(jie)工(gong)(gong)藝(yi)評定(ding)，并(bing)根據焊(han)接(jie)(jie)(jie)工(gong)(gong)藝(yi)評定(ding)的結(jie)果制定(ding)相應的施工(gong)(gong)焊(han)接(jie)(jie)(jie)工(gong)(gong)藝(yi)規范。

（7）焊接(jie)(jie)(jie)H型鋼、翼緣(yuan)板(ban)不應再設縱向拼(pin)接(jie)(jie)(jie)縫，只允許長(chang)度(du)拼(pin)接(jie)(jie)(jie)，而腹板(ban)則(ze)長(chang)度(du)、寬度(du)均可拼(pin)接(jie)(jie)(jie)，但(dan)翼緣(yuan)板(ban)或腹板(ban)接(jie)(jie)(jie)縫應錯(cuo)開200mm以上(shang)。

（8）為了檢驗其制作的整體性，鋼構件在出(chu)廠(chang)前應進行工(gong)廠(chang)拼(pin)裝(zhuang)(zhuang)，預拼(pin)裝(zhuang)(zhuang)均應在工(gong)廠(chang)支(zhi)承(cheng)凳進行。支(zhi)承(cheng)凳或平(ping)臺應測量找平(ping)，且預拼(pin)裝(zhuang)(zhuang)時(shi)不應使用大錘錘擊，檢查時(shi)應拆除全部臨時(shi)固定和拉緊裝(zhuang)(zhuang)置。

（9）鋼結構安裝前應審(shen)查安裝起吊施工方案(an)。

（10）鋼結構(gou)安裝檢驗批(pi)，應(ying)在進場驗收(shou)和焊接(jie)連接(jie)、緊(jin)固件連接(jie)制作等分項工(gong)、工(gong)程(cheng)驗收(shou)合格的基(ji)礎上(shang)進行驗收(shou)。

（12）安裝偏差的(de)檢測，應在結構形(xing)成空間剛度單元亦(yi)連接固定(ding)后進(jin)行。

（12）安裝時，必須控制屋面、平臺等(deng)的施(shi)工荷載。

（13）鋼結構(gou)(gou)(gou)安裝工程質(zhi)量(liang)(liang)應從原材料質(zhi)量(liang)(liang)和構(gou)(gou)(gou)件(jian)質(zhi)量(liang)(liang)抓起，不但要嚴格控(kong)制(zhi)構(gou)(gou)(gou)件(jian)制(zhi)作質(zhi)量(liang)(liang)，而且(qie)要控(kong)制(zhi)構(gou)(gou)(gou)件(jian)運輸、堆放和吊(diao)裝質(zhi)量(liang)(liang)。采(cai)取切實可靠的措施，防止構(gou)(gou)(gou)件(jian)在(zai)上述(shu)過程中(zhong)變(bian)形或(huo)脫漆。如不慎構(gou)(gou)(gou)件(jian)產(chan)生(sheng)變(bian)形或(huo)脫漆，應矯正或(huo)補漆后再安裝。

（14）在施工(gong)(gong)(gong)(gong)單位自(zi)檢合格的(de)基礎上，檢驗(yan)(yan)(yan)鋼(gang)結(jie)構工(gong)(gong)(gong)(gong)程(cheng)施工(gong)(gong)(gong)(gong)質量的(de)驗(yan)(yan)(yan)收記錄。工(gong)(gong)(gong)(gong)程(cheng)中的(de)鋼(gang)結(jie)構屬于子分部(bu)工(gong)(gong)(gong)(gong)程(cheng)，按照檢驗(yan)(yan)(yan)批(pi)、分項工(gong)(gong)(gong)(gong)程(cheng)、子分項、子分部(bu)工(gong)(gong)(gong)(gong)程(cheng)進行驗(yan)(yan)(yan)收。
