Die for manufacturing steel reticulated shell purline connecting gusset plate

The utility model relates to a production method of a steel frame reticulated shell structure, in particular to a die for manufacturing a steel reticulated shell purline connecting gusset plate. The problem that due to the fact that the angle of the gusset plate is not standard, position and angle deviation occurs in the purline installation process is solved. The die structure comprises a bottomsupporting frame, a platform plate, a main purlin holder backup plate, a main purlin holder rib plate movable backup plate, a secondary purlin holder platform plate and a secondary purlin holder backup plate. The mold is fully combined with the structural characteristics of the gusset plate, displacement and deviation of all structures of the gusset plate in the connecting and assembling process are limited through the horizontal and vertical relation in the mold, the purline gusset plate is assembled on the specific mold, and the horizontal position and perpendicularity of connecting plate installation are accurate;
