Hubei Jinggong Steel Structure Co.,Ltd. 在现代建筑中,建筑造型变得越来越新颖,结构也越来越复杂,因此传统的钢筋混凝土结构无法满足特殊的结构要求,只能由钢结构工程来实现,钢结构工程中有大量弯扭曲面成型构件的应用。从钢结构深化设计、焊缝设计、零件套料及成型、构件装配、构件焊接及成型精度检测等方面论述了钢结构弯扭桁架的制作及精度控制措施,为此类钢构件的加工和制作提供了可靠的参考方案。 In modern architecture,the architectural modeling is becoming more and more novel,and the structure is also becoming more and more complex. Therefore,the traditional reinforced concrete structure can not meet the special structural requirements,this can only be achieved by steel structure engineering,and the curved torsion surface molding members are widely used in steel structure engineering. The fabrication and precision control measures of steel structure curved torsion trusses are discussed from the aspects of deepening design of steel structure,weld design,parts nesting and forming, member assembly,member welding and forming precision detection,which provides a reliable reference scheme for the processing and fabrication of similar steel members. 弯扭 菱形箱体 制作技术 精度控制 curved torsion diamond box body fabrication technology precision control TU758.11 2022-03-08 11 50
