12、積為36066.67，鋼筋砼剪力墻結(jié)構(gòu)體系。施工現(xiàn)場面積大，幢數(shù)多，水平和垂直運輸難度大，我公司決定在現(xiàn)場設(shè)置塔吊三臺，1# qtz-63二臺，1#塔吊qtz-65162塔吊位置設(shè)定21 qtz-63塔吊基礎(chǔ)位于在c6號樓北側(cè)，qtz-63塔吊基礎(chǔ)位于在c7號樓北側(cè)，qtz-6516塔吊基礎(chǔ)位于在c3 c4 c5 c8樓之間，3塔吊主要參數(shù) 項目 型號 臂長最大起重量起重力矩自由高度電力qtz-6348m6t630kg/m30米42kwqtz-6348m6t630kg/m35米42kwqtz-651665 m10t160 kg/m 40米45kw4.塔吊施工4.1塔吊基礎(chǔ)施工具體見塔吊基礎(chǔ)圖4

13、.2塔吊的安裝安裝前全面檢查塔機各部件塔吊基礎(chǔ)施工預埋支腿安裝過度節(jié)安裝頂升套架安裝3節(jié)標準節(jié)安裝回轉(zhuǎn)裝置安裝引進大梁安裝駕駛室安裝塔帽安裝平衡臂安裝48米起重臂安裝配重傳繞各部鋼絲繩塔吊自升檢查合格投入工作。1#塔吊初始高度為30米，2#塔吊初始高度為35米，3#塔吊初始高度為40米， 4.3塔吊的附著1）附墻安裝前拆裝處務(wù)必查看現(xiàn)場，是否已具備附墻安裝條件，同時熟悉方案。2）拉桿組件/連接件/標準節(jié)等進場。3）吊裝附著框架。（a）將一側(cè)的附著框架吊至塔身附著點處。（b）將另一側(cè)的附著框架吊起就位然后將兩外側(cè)框連成一體。（c）框架先調(diào)平后固定。4）吊裝與墻體連接的雙孔支座以及背板，用穿墻螺栓

14、/螺母連接，螺母必須擰到位，并緊固連接。5）吊裝附墻拉桿，拉桿銷接，并封上開口銷，外套節(jié)與插件先鑲嵌，暫不焊接。6）調(diào)整塔身垂直度。調(diào)整時，應(yīng)先吊起一重物，移動起重小車，調(diào)整前后力矩，處于平衡位置后，用經(jīng)緯儀監(jiān)測塔身兩方向的偏差，調(diào)整好垂直度（偏差不超過3/1000），焊縫厚度為10mm，焊縫不得有氣孔、夾渣等缺陷。4.4塔吊的拆卸步驟4.4.1塔吊的拆除程序與安裝程序相反。4.4.2塔吊自降標準節(jié)至最底，降級作業(yè)必須嚴格按說明書的規(guī)范進行。4.4.3拆除塔吊卷揚鋼絲繩及配重：將小車行至臂跟，固定在臂架上，卸下前后鋼絲繩，后繩繞在小車卷筒上，卸下前繩。切斷電源，拆除電纜。吊下配重。4.4.4拆

15、除起重臂：汽車吊吊住起重臂，用張緊器拆卸拉桿，落下整個臂架，并將其放在地面。4.4.5拆除塔吊平衡臂。4.4.6拆除塔帽：拆除回轉(zhuǎn)；拆除塔吊的頂升套架。4.4.7拆除塔吊剩余標準節(jié)及過度節(jié)。4.4.8拆除節(jié)，需用氣焊將預埋于建筑底板的節(jié)預埋割除，以免影響建筑裝修。4.4.9清點物件，運出施工現(xiàn)場。5、 群塔作業(yè)5.1群塔作業(yè)防碰撞措施5.1.1塔吊在初期定位安裝、中期使用（頂升）以及后期拆除都應(yīng)考慮到可能發(fā)生的碰撞事故，為避免塔吊間發(fā)生碰撞事故，保證塔吊正常、安全地使用，群塔作業(yè)防碰撞措施尤為重要。5.1.2塔吊在水平方向的防碰撞措施 考慮到現(xiàn)場周圍環(huán)境的限制，并結(jié)合施工的需要，確定塔吊在現(xiàn)場

16、的布置，在塔吊定位時已把各塔之間的距離均大于相關(guān)的塔吊臂長。這樣就保證了安全規(guī)程中：三臺塔吊之間的最小架設(shè)距離應(yīng)保證處于低位的塔吊臂架端部與處于高位塔吊的塔身之間有2米距離由此，可以解決三臺以上塔吊之間低位塔吊的起重臂與高位塔吊的塔身發(fā)生碰撞問題。5.1.3 塔吊在垂直方向的防碰撞措施（1）低位的塔吊的起重臂與高位塔吊起重鋼絲繩之間防碰撞措施 由于受施工需要的影響，有可能發(fā)生低位的塔吊的起重臂與高位塔吊起重鋼絲繩的碰撞事故。為杜絕此類事故發(fā)生，必須對每一臺塔吊的工作區(qū)進行合理劃分，避免出現(xiàn)塔吊交叉工作區(qū)。同時，必須配備有合格操作證的、經(jīng)驗豐富的信號指揮工，確保指揮塔吊回轉(zhuǎn)作業(yè)時，低塔的起重臂不

17、碰撞高塔的起升鋼絲繩。當現(xiàn)場風速達到5級風時，相當于風速達到10.813.8米/秒時，塔吊必須停止作業(yè)。另外，要配備操作熟練、有責任心的塔吊司機為現(xiàn)場服務(wù)，塔吊在每次使用后或在非工作狀態(tài)下，將塔吊的吊鉤升至頂端。 （2）高位塔吊的起重臂下端與低位塔吊最高部件防碰撞措施由于相鄰的回轉(zhuǎn)面有交叉區(qū)域，所以低位塔吊的起重臂與高位塔吊的起重臂有可能發(fā)生碰撞。由各塔吊初裝吊鉤高度可知各塔吊鉤高度差均大于6米，這樣就保證了安全規(guī)程中：三臺塔吊之間架設(shè)高差處于低位塔吊的較高位置的部件（塔頂，拉桿等）與處于高位塔吊的最底位置部件（已升至最高的吊鉤、配重等）間的垂直距離不得小于2米。5.1.4塔吊與現(xiàn)場周邊建筑及

18、設(shè)施的防碰撞措施施工現(xiàn)場周圍有建筑物，塔吊設(shè)計定位時已避開這些建筑。為穩(wěn)妥起見，在塔吊現(xiàn)場定位時，必須對其復核。在實際施工中，還要密切關(guān)注現(xiàn)場以外的情況，塔吊初次頂升要超過臨近低層建筑物的高度，還要注意周邊情況尤其是現(xiàn)場工人和車輛，還要避讓附近電力及通訊設(shè)施，以免造成不必要的傷害或破壞。綜上所述，本工程在塔吊安裝時應(yīng)充分考慮周邊情況及群塔作業(yè)影響應(yīng)作到：5.2群塔作業(yè)信號工指揮措施5.2.1信號工在服裝上嚴格區(qū)分，工地為每一臺塔吊設(shè)2人指揮，指揮人員要求熟悉機械操作規(guī)程，熟悉指揮信號經(jīng)過專門的培訓，持證上崗。5.2.2信號工在哨音上要有明顯區(qū)分，信號簡潔、明確;如使用對講機要鎖定專門頻道;指揮
