某尿素造粒塔塔顶钢结构骨架由3道环梁圈和18根辐射梁组成。对尿素造粒塔电动滑模施工平台的施工流程进行了详细的介绍,并对结构进行使用阶段和吊装过程的分析。利用3D3S建立空间计算模型,对施工平台的结构受力及位移进行计算,较真实地反映结构的实际受力状态,确保结构安全。该方案加快了施工进度,降低了工程造价,取得了较好的应用效果。 A urea granulation tower overhead steel framework consists of three ring beams and 18 radiation beams. The construction process of the electric slip-form construction platform of the urea prilling tower is introduced in detail, and the use of the structure and the hoisting process are analyzed. The 3D3S model is used to establish the space calculation model to calculate the force and displacement of the structure of the construction platform. The 3D3S realistically reflects the actual stress state of the structure and ensures the structural safety. The program to speed up the construction progress and reduce the project cost, and achieved good results.
