9.1吊裝索具選用

9.1.1下部桁架吊裝索具選擇及驗(yàn)算

鋼絲繩選擇：

桁架分段吊裝分段最重約24.It,單個(gè)吊點(diǎn)最不利負(fù)載為24.1*1.5/4=9.04t(考慮1.5的活載

系數(shù)，按4點(diǎn)受力計(jì)算)，單根鋼絲繩受力按9.04噸考慮，鋼絲繩受力按6倍的安全系數(shù)，再考慮

鋼絲繩之間荷載不均勻系數(shù)0.82,則鋼絲繩的鋼絲破斷拉力為：F=90.4X6/0.82=661.5kN.

選用公稱抗拉強(qiáng)度1850Mpa的6X37鋼絲繩，直徑32.Einm,查得該鋼絲繩鋼絲破斷拉力總和為

7ilkN>661.5kN,滿足要求。

卸扣選擇：

分段吊裝選用T-BX9.5-7/8型卸扣，額定荷載9.5t大于鋼絲繩拉力9.04tQ

因此本工程網(wǎng)殼吊裝選用T-BX9.5-7/8型卸扣作為吊索具安全。

9.1.2網(wǎng)殼分塊吊裝索具選擇及驗(yàn)算

鋼絲繩選擇：

網(wǎng)殼分塊吊裝分段最重約36.9t,單個(gè)吊點(diǎn)最不利負(fù)載為36.9*1.5/4=13.84t(考慮1.5的活載

系數(shù)，按4點(diǎn)受力計(jì)算)，單根鋼絲繩受力按13.84噸考慮，鋼絲繩受力按6倍的安全系數(shù)，再考慮

鋼絲繩之間荷載不均勻系數(shù)0.82,則鋼絲繩的鋼絲破斷拉力為：F=138.5X6/0.82=1013kNo

9.2.1分析設(shè)計(jì)說明

根據(jù)本工程吊裝區(qū)域網(wǎng)殼分塊情況，選取幾個(gè)典型吊裝單元進(jìn)行計(jì)算分析，對屋蓋結(jié)構(gòu)構(gòu)件吊

裝分塊的變形及構(gòu)件應(yīng)力進(jìn)行驗(yàn)算分析結(jié)果如下。

9.2.2荷載與荷載組合

結(jié)構(gòu)自重由程序自動(dòng)計(jì)算，并對其進(jìn)行L35倍的放大以考慮施工荷載效應(yīng)；荷載組合取分項(xiàng)系

數(shù)取1.35,動(dòng)力放大系數(shù)（1.2~1.5）取1.35。因此計(jì)算荷載組合為1.35*1.35恒載。
