Virtual pre-assembly process for deformed steel
The invention discloses a deformed steel virtual pre-assembly process, and relates to the technical field of steel structures. Comprising the following steps: carrying out three-dimensional grating surface scanning on a component by adopting industrial-grade precision one-time molding automatic three-dimensional point cloud scanning equipment; virtual space construction is conducted on each component section, entity digital scanning is conducted on the steel structure components and the sections through a three-dimensional scanner, and three-dimensional coordinates of the components and the sections are obtained; all the coordinate points are integrated through graphic processing software, and a BIM model is established; comparing the dimensions of the whole member and the segments to obtain the deviation of the front and rear models, and then translating and overturning the models of the adjacent member segments by using software to obtain a virtual pre-assembly model of the deformed steel structure; and according to the pre-assembly model obtained after entity scanning of the component, after component connecting points are checked, data information is transmitted to a positioning device so that steel structure assembly can be conducted. According to the method, time and labor are saved during virtual splicing, the manufacturing period is shortened, the cost is reduced, and the subsequent entity splicing efficiency and precision are higher.
本发明公开了一种异型钢虚拟预拼装工艺，涉及钢结构技术领域。包括以下步骤：采用工业级精度一次性成型自动三维点云扫描设备，对构件进行三维光栅面扫描；对每个构件节段进行虚拟空间构建，三维扫描仪对钢结构构件与节段进行实体数字化扫描，获取构件与节段的三维坐标；通过图形处理软件将各坐标点进行整合，建立BIM模型；对比构件整体及节段的尺寸以得到前后模型的偏差，再利用软件对相邻的构件节段的模型进行平移、翻转操作得出异型钢结构虚拟预拼装模型；根据构件实体扫描后的预拼装模型，对构件连接点进行检查后将数据信息传递至定位装置以进行钢结构拼装。本发明虚拟拼装省时省力，缩短制作周期，降低成本，后续实体拼装效率及精准度更高。
