Double-layered diagonal inclined truncated joint latticed shell unit splicing method
The invention relates to a double-layered diagonal inclined truncated joint latticed shell unit splicing method and belongs to the technical field of building steel structure construction. The methodcomprises the following steps of first, carrying out a technical preparation process on a lifted block unit; then welding and forming an upper drum, a lower drum and a web member, lofting an identifier to the center point of each upper and lower drums on a splicing site by means of a total station, lofting the outer diameter of an orthographic projection of a truncated joint to the ground by taking the center point of the identifier, and identifying the upper and lower drums; then snapping lines to connect the center points of the lower drums with a duct as a bed-jig landmark; placing a bed-jig according to a landmark line and arranging a lower drum supporting bracket in each lower drum splicing position; putting each lower drum into the lower drum supporting bracket for spot welding temporary fixation; then splicing a lower chord, an upper chord and a diagonal web member successively; and finally, implementing welding. The double-layered diagonal inclined truncated joint latticed shell unit splicing method has the advantages of being high in construction efficiency, good in safety and reliability and short in construction period, improves the splicing quality and the splicing quality and lowers the construction cost as well.
本发明涉及一种双层斜交斜放鼓节点网壳单元拼装方法，所属建筑钢结构施工技术领域，包括如下操作步骤：先将吊装分块单元进行技术准备过程。然后先将上鼓、下鼓和腹杆进行焊接成型，用全站仪将每个上鼓、下鼓的中心点在拼装场地上放样标识，以标识的中心点为圆心，将鼓节点的正投影外径放样画与地面上，并做好上鼓和下鼓标识。接着用墨斗将每个下鼓的中心点弹线连接，作为胎架地样。根据地样线放置胎架，在每个下鼓拼装位置设置一个下鼓支撑托架。将下鼓放入下鼓支撑托架内进行点焊临时固定。再依次对下弦杆、上弦杆及斜腹杆进行拼装，最后再实施焊接。具有施工效率高、安全可靠性好和施工周期短的优点。提高拼装质量和精度，同时降低了施工成本。
