鋼結構工程施工的質量如何進行控制?今天甘肅金興達鋼結構工程有限公司小編來給您講講:

一(yi)、做好工(gong)程開工(gong)前準(zhun)備工(gong)作

(1)強化(hua)施(shi)工(gong)(gong)圖(tu)紙的會審工(gong)(gong)作。圖(tu)紙是工(gong)(gong)程(cheng)施(shi)工(gong)(gong)的依(yi)據，工(gong)(gong)程(cheng)開工(gong)(gong)前項(xiang)目控(kong)制機構要組織(zhi)控(kong)制人(ren)員熟悉工(gong)(gong)程(cheng)圖(tu)紙與項(xiang)目有(you)關(guan)的規范(fan)標準、工(gong)(gong)藝技術條件，充分(fen)領會設(she)計意圖(tu)。

(2)認真審查鋼結構安裝施(shi)(shi)(shi)工組織(zhi)設計。施(shi)(shi)(shi)工組織(zhi)設計是(shi)施(shi)(shi)(shi)工單位全(quan)面指導工程實(shi)施(shi)(shi)(shi)的技術性(xing)文件，施(shi)(shi)(shi)工組織(zhi)設計的完善程度(du)直接(jie)影響工程的質量、進度(du)。因此，鋼結構安裝工程施(shi)(shi)(shi)工組織(zhi)設計審(shen)查要(yao)針對性(xing)和重(zhong)點。

審查的重點內容有：

a.質量保證體系和技(ji)術管理體系的建立;

b.特(te)殊工種的培訓合格證(zheng)和上崗(gang)證(zheng);

c.新工藝的應用;

d.對工程項(xiang)目的針對性;

e.質量(liang)、進度控(kong)制的措施和方法;

f.施工(gong)計劃(hua)(工(gong)期(qi))的安排。

二、加(jia)強(qiang)現場(chang)施工過程(cheng)中的質量控制

(1)作好(hao)鋼結(jie)構基礎(chu)(chu)工程(cheng)(cheng)的(de)質量(liang)(liang)控(kong)制(zhi)(zhi)。鋼結(jie)構工程(cheng)(cheng)的(de)基礎(chu)(chu)一般都采用混(hun)凝(ning)土獨立柱基礎(chu)(chu)，基礎(chu)(chu)的(de)混(hun)凝(ning)土及(ji)鋼筋(jin)、模板的(de)施工與其他工程(cheng)(cheng)的(de)施工工序及(ji)方法相同，而基礎(chu)(chu)獨立柱中(zhong)(zhong)預埋的(de)螺(luo)栓是(shi)質量(liang)(liang)控(kong)制(zhi)(zhi)的(de)重點，單個螺(luo)栓及(ji)每(mei)組螺(luo)栓之間的(de)間距、高低的(de)偏差，直接影響鋼結(jie)構工程(cheng)(cheng)的(de)安裝質量(liang)(liang)，我們在控(kong)制(zhi)(zhi)質量(liang)(liang)控(kong)制(zhi)(zhi)過程(cheng)(cheng)中(zhong)(zhong)，要求施工單位必(bi)須嚴格控(kong)制(zhi)(zhi)好(hao)。

(2)鋼結構主體工程的質量控(kong)制(zhi)。

a.鋼構件的質(zhi)量驗(yan)收(shou)。鋼(gang)構件的加工已(yi)實(shi)行工廠化生(sheng)產，鋼(gang)構件的進場質(zhi)量驗(yan)收(shou)就非常重要。

b.鋼構(gou)(gou)件安裝(zhuang)質量控制。柱、梁安裝(zhuang)時(shi)，主要(yao)檢(jian)查柱底(di)版下的墊鐵是否墊實(shi)、墊平(ping)，柱是否垂直和位移，梁的垂直、平(ping)直、側向彎曲、螺(luo)栓的擰緊程(cheng)度以(yi)及摩擦(ca)面清理，驗收合格后(hou)，方可起吊。當鋼結構(gou)(gou)安裝(zhuang)形成(cheng)空(kong)間固(gu)定單元，并進行驗收合格后(hou)，要(yao)求施工單位將(jiang)柱底(di)板和基礎(chu)頂面的空(kong)間用膨脹混凝土(tu)二(er)次澆筑密實(shi)。

c.螺栓(shuan)(shuan)安裝(zhuang)質(zhi)量的控制。鋼結構工程(cheng)中螺栓(shuan)(shuan)連接(jie)一般(ban)用(yong)高強(qiang)螺栓(shuan)(shuan)和(he)普(pu)通螺栓(shuan)(shuan)，普(pu)通螺栓(shuan)(shuan)連接(jie)，每個螺栓(shuan)(shuan)一端不(bu)(bu)得(de)墊(dian)2個以上墊(dian)片，螺栓(shuan)(shuan)孔(kong)不(bu)(bu)得(de)用(yong)氣割擴(kuo)孔(kong)，螺栓(shuan)(shuan)擰(ning)緊后外露螺紋(wen)不(bu)(bu)得(de)少于(yu)2個螺距;高強(qiang)螺栓(shuan)(shuan)使用(yong)前我們檢(jian)查螺栓(shuan)(shuan)的合格證(zheng)和(he)復試單(dan)，安裝(zhuang)過(guo)程(cheng)中板疊接(jie)觸(chu)面(mian)應(ying)平整，接(jie)觸(chu)面(mian)必須大(da)于(yu)75%，邊(bian)緣縫隙不(bu)(bu)得(de)大(da)于(yu)0.8mm，高強(qiang)螺栓(shuan)(shuan)應(ying)自由穿入，不(bu)(bu)得(de)敲打和(he)擴(kuo)孔(kong)。

(3)門窗(chuang)(chuang)(chuang)(chuang)工(gong)程安(an)裝(zhuang)質(zhi)(zhi)量的(de)控(kong)制。鋼(gang)(gang)窗(chuang)(chuang)(chuang)(chuang)安(an)裝(zhuang)質(zhi)(zhi)量的(de)控(kong)制重點有兩(liang)點，一是(shi)，鋼(gang)(gang)窗(chuang)(chuang)(chuang)(chuang)進場合(he)格證(zheng)、產品試驗報告及外觀(guan)的(de)檢查(cha)。二是(shi)，鋼(gang)(gang)窗(chuang)(chuang)(chuang)(chuang)和固定(ding)鋼(gang)(gang)窗(chuang)(chuang)(chuang)(chuang)的(de)立(li)(li)柱(zhu)(zhu)之(zhi)間(jian)(jian)的(de)間(jian)(jian)隙(xi)控(kong)制。先施工(gong)固定(ding)鋼(gang)(gang)窗(chuang)(chuang)(chuang)(chuang)的(de)立(li)(li)柱(zhu)(zhu)，有可能出現(xian)鋼(gang)(gang)窗(chuang)(chuang)(chuang)(chuang)與(yu)立(li)(li)柱(zhu)(zhu)之(zhi)間(jian)(jian)縫(feng)隙(xi)過大或鋼(gang)(gang)窗(chuang)(chuang)(chuang)(chuang)安(an)不上。我(wo)們在控(kong)制過程中(zhong)，要(yao)求(qiu)施工(gong)單(dan)位先固定(ding)鋼(gang)(gang)窗(chuang)(chuang)(chuang)(chuang)一邊的(de)立(li)(li)柱(zhu)(zhu)，待鋼(gang)(gang)窗(chuang)(chuang)(chuang)(chuang)完全固定(ding)就位后，再(zai)焊接(jie)另一邊的(de)立(li)(li)柱(zhu)(zhu)，這樣保證(zheng)鋼(gang)(gang)窗(chuang)(chuang)(chuang)(chuang)與(yu)立(li)(li)柱(zhu)(zhu)之(zhi)間(jian)(jian)無縫(feng)隙(xi)。

鋼結(jie)(jie)構工(gong)(gong)程(cheng)(cheng)的(de)施工(gong)(gong)在(zai)我國剛起步，在(zai)鋼結(jie)(jie)構工(gong)(gong)程(cheng)(cheng)施工(gong)(gong)控(kong)制過程(cheng)(cheng)中(zhong)，要真正發揮工(gong)(gong)程(cheng)(cheng)控(kong)制的(de)作用，要求工(gong)(gong)程(cheng)(cheng)在(zai)施工(gong)(gong)時(shi)要嚴格(ge)控(kong)制好進度(du)，同時(shi)工(gong)(gong)程(cheng)(cheng)師也要做好質(zhi)量(liang)把關工(gong)(gong)作，這樣才(cai)能保證鋼結(jie)(jie)構工(gong)(gong)程(cheng)(cheng)的(de)施工(gong)(gong)質(zhi)量(liang)。
