摘要
结合工程案例的实际情况,对武汉国际博览中心洲际酒店椭球体网壳圆管构件的加工工艺进行研究,介绍加工细节及质量问题解决措施。对于弧形弦杆的弯制,分析顶弯机冷弯工艺及中频热弯工艺的优劣及在工程实际中的应用;对于直腹杆,阐述相贯线切割的加工工艺及质量控制关键点。结果表明:按此加工方案,该工程构件加工质量得到了很好的保障。
Combined with the practical situation of engineering cases,the processing technology for pipe components of ellipsoidal reticulated shell of Wuhan International Expo Center Intercontinental Hotel was investigated,the processing details and the solving measures for quality problem were also introduced.As for the bending of arc-shaped chords,the advantage and disadvantage of cold-bending technology by bending machine and medium-frequency hot-bending technology were analyzed,as well as the application in practical works.The processing technology for intersecting line cutting technology and key points of quality control of straight web members were described.The results showed that the processing quality of members were guaranteed well in this project according to the proposed processing scheme.
