梅溪湖大截面螺旋体三角箱型构件匹配制作工艺研究

RESEARCH ON MATCHING MANUFACTURING TECHNIQUE FOR LARGE CROSS SECTION SPIRAL TRIANGLE BOX COMPONENT OF CITY ISLAND IN MEIXI LAKE

针对梅溪湖大截面螺旋体三角箱体结构,利用三维坐标点控制单元件的装配精度;采用匹配制作和循环预拼装保证结构整体线型。通过控制焊接顺序和焊接热输入减小焊接变形;对箱体内部隐蔽焊缝采用面板开槽焊接,确保结构强度。

Aiming at large cross section spiral triangle box component of city island in Meixi lake,the three-dimensional coordinate control point was used to control the unit assembly accuracy. Matching manufacturing and recycling preassembled was applied to ensure the linetype of overall strucuture. The welding deformation was reduced by controlling welding sequence and welding heat input. The internal concealed weld of the box was welded by slotted roof,thus ensuring the structural strength.
