Ultrahigh single-layer portal frame steel structure hoisting construction method
The invention relates to an ultrahigh single-layer portal frame steel structure hoisting construction method. The ultrahigh single-layer portal frame steel structure hoisting construction method comprises the following steps that step 1, a steel column is hoisted, specifically, a reference elevation point is made at the bottom of the steel column for installation and adjustment, a central axis is released on the foundation surface, then a positioning line of the steel column is calculated, and an obvious mark is made for installation and adjustment; step 2, a steel beam is hoisted; and step 3, the hoisting stability is analyzed, specifically, the type of a lifting lug is a top plate type lifting lug, calculation is carried out according to the maximum weight 9,900kg of a single steel column member, the lifting lug hoisting load calculation value is 100KN, and the vertical load Fv of the lifting lug and the transverse load Fh of the lifting lug are calculated to be 165 kN and 44.212 KN correspondingly. The ultrahigh single-layer portal frame hoisting construction method is creatively provided, hoisting is stable, the overall rigidity is high, and the ultrahigh single-layer portal frame hoisting construction method is suitable for application and popularization.
本发明涉及一种超高型单层门型架钢结构吊装建造方法，步骤一：钢柱吊装：钢柱底部做基准标高点，作为安装调整用；在基础面上放出中心轴线，而后计算出钢柱的定位线，并做出明显标识，以便安装调整用；步骤二：钢梁吊装：步骤三：吊装稳定性分析：吊耳类型为顶部板式吊耳，按照钢柱单构件最重9900kg计算，吊耳起重荷载计算取值为100KN，计算出吊耳竖向荷载为Fv为165 kN，横向荷载Fh为44.212KN；本发明开拓性地提出超高型单层门型架吊装施工方法，吊装稳定，整体刚度强，适合推广使用。
