Irregular multi-curve triangular pyramid welded ball net rack construction method
The invention belongs to the technical field of steel structure construction, and discloses a construction method of an irregular multi-curve triangular pyramid welded ball net rack, which comprises the following steps: establishing a three-dimensional model of an extremely irregular multi-curve triangular pyramid welded ball net rack, designing lifting points of partition sections, simulating a working condition 1, a working condition 1 + 1... a working condition (X-1), lifting partition section units under a working condition X, and constructing a three-dimensional model of the irregular multi-curve triangular pyramid welded ball net rack. And analyzing the stress and deformation conditions of the net rack rod pieces, performing lifting simulation on all sections, analyzing the stress and deformation conditions of the net rack rod pieces when all irregular sections are folded under the condition of full working condition conversion in the whole process, and determining the folding sequence. And correcting a lifting suspension point arrangement scheme of the working condition X, and reducing the number of arranged suspension points as much as possible, and mounting, lifting and closing, acceptance and unloading of the net rack. According to the method, an informatization means is adopted for accurate simulation analysis, an optimal partition and construction scheme is formed, the problem of a cantilever part of a welded ball net rack structure with an extremely irregular plane shape is solved, the construction cost is saved, and the construction efficiency is improved. And the construction period is further shortened.
本发明属于钢结构施工技术领域，公开了一种不规则多曲三角锥焊接球网架施工方法，包括如下步骤：建立极不规则多曲三角锥焊接球网架三维模型，分区版块吊点设计，模拟工况1、工况1+1···工况(X‑1)、工况X下分区版块单元提升，并分析网架杆件应力和变形情况，全部版块提升模拟，分析全过程全工况转换条件下，各个不规则版块合拢时网架杆件应力和变形情况，确定合拢顺序。修正工况X的提升吊点布置方案，尽量减少吊点布置数量，网架安装、提升与合拢，验收及卸载，本发明采用信息化手段精准模拟分析，形成最佳分区和施工方案，解决了平面形状极不规则的焊接球网架结构悬挑部位的难题，节约了施工成本，进一步地缩短了施工工期。
