泰立鋼結構公司為您分享:汽車式起重機主要是分為輕型中型和重型三個類型,它的底盤兩側是具備四個支腿這是為了提升起重機的穩定情況,同樣汽車式起重機的性能也比較好,運轉速度比較快。根據太原鋼結構施工場地的要求來選擇是使用中型的起重機或者是重型的起重機,作業之后將制動器進行固定。
吊(diao)裝(zhuang)的(de)(de)(de)方案是(shi)按照場(chang)地工程所具備的(de)(de)(de)特征,工期長短(duan)以及施工的(de)(de)(de)情況,來使用兩次(ci)吊(diao)裝(zhuang)或(huo)者(zhe)是(shi)分段拼裝(zhuang)的(de)(de)(de)方法進行(xing)吊(diao)裝(zhuang),現場(chang)吊(diao)裝(zhuang)有時會用到大(da)型的(de)(de)(de)機(ji)械吊(diao)裝(zhuang),除此之(zhi)外需(xu)要注意的(de)(de)(de)是(shi)吊(diao)裝(zhuang)的(de)(de)(de)順序問題(ti),此項十分重要。
山西鋼結構工程的吊裝方案應該要符合工程特點,嚴格布局好吊裝的順序。此外,吊車的確定應貼合工程現場的實際情況,因為開展吊裝作業的時候,吊車只能在一些靠近路口的地方通行,其他狹窄的位置根本無法進行作業,除此之外,還應該考慮到機械的功率和靈活性,比如每根鋼構件的重量,或者是起吊的高度以及吊車的型號等,這些內容也應該提前確定好。
鋼構(gou)件吊裝施工(gong)技術在現(xian)(xian)代建(jian)筑(zhu)施工(gong)過(guo)程中占據著舉足(zu)輕(qing)重(zhong)的(de)位置(zhi)。但(dan)是,我國(guo)現(xian)(xian)階段的(de)吊裝施工(gong)技術掌握方法并不是十分成熟,所以限(xian)制了行業發(fa)展,而施工(gong)安全(quan)管理要求(qiu)也應該(gai)提高,這(zhe)都是現(xian)(xian)階段很大的(de)挑戰(zhan)。
泰立鋼結構公司為您分享:山西鋼結構工程保護包括防火、防腐、防銹,一般在防火涂料處理后不需要進行防銹處理,但在腐蝕性氣體建筑中仍需進行防腐處理。目前防火涂料種類較多,如TN系列、MC-10等,其中MC-10防火涂料包括醇酸磁性涂料、氯化橡膠涂料、氟橡膠涂料和氯磺化涂料。
在(zai)施工過(guo)程中,應(ying)根據鋼(gang)(gang)結構(gou)(gou)類型、耐火等(deng)級要(yao)求(qiu)和環(huan)境要(yao)求(qiu)選擇(ze)合適的(de)(de)(de)涂層厚度和涂層厚度。鋼(gang)(gang)結構(gou)(gou)的(de)(de)(de)工作條件在(zai)低(di)溫下(xia)(xia)容(rong)(rong)(rong)易(yi)冷(leng)脆,因(yin)此在(zai)低(di)溫溫條件下(xia)(xia)工作的(de)(de)(de)結構(gou)(gou),特別是焊(han)接結構(gou)(gou),應(ying)選擇(ze)耐低(di)溫脆性(xing)好的(de)(de)(de)結構(gou)(gou)鋼(gang)(gang)。此外,露天結構(gou)(gou)的(de)(de)(de)鋼(gang)(gang)容(rong)(rong)(rong)易(yi)產生及時性(xing),有(you)害介質的(de)(de)(de)鋼(gang)(gang)容(rong)(rong)(rong)易(yi)零(ling)腐蝕(shi)、疲勞和斷裂,也(ye)應(ying)選擇(ze)不同的(de)(de)(de)材(cai)料。鋼(gang)(gang)厚度薄,軋(ya)制(zhi)次數多(duo),軋(ya)制(zhi)壓縮比大(da),鋼(gang)(gang)壓縮比小,塑性(xing)、沖擊韌性(xing)和焊(han)接性(xing)能差。因(yin)此,較厚的(de)(de)(de)焊(han)接結構(gou)(gou)應(ying)采用較好的(de)(de)(de)鋼(gang)(gang)材(cai)。吊裝鋼(gang)(gang)構(gou)(gou)件,增加或減少光滑(hua)度,避(bi)免(mian)緊急制(zhi)動(dong)或休克(ke)。在(zai)人員(yuan)中,指(zhi)揮(hui)信號清(qing)晰、響亮(liang)、清(qing)晰,嚴禁非法操(cao)作。
