The embodiment of the invention discloses a trepanning structure. The trepanning structure comprises a trepanning main body and an inlaying plate, wherein the trepanning main body is provided with at least one through hole and an inlaying plate preformed hole, and part of the edge of the through hole is connected with part of the edge of the inlaying plate preformed hole; and the inlaying plate is installed in the inlaying plate preformed hole, and the thickness of the inlaying plate is greater than that of the edge of the through hole. By additionally arranging the inlaying plate at the trepanning position, the structural strength of the trepanning structure at the trepanning position is remarkably improved, and the technical problem in the prior art that after trepanning, structural deformation and damage are caused during transportation or welding is solved.
本发明实施例公开了一种开孔结构,所述开孔结构包括开孔主体和嵌补板,所述开孔主体上具有至少一个通孔和一个嵌补板预留孔,所述通孔的部分边缘与所述嵌补板预留孔的部分边缘相接;所述嵌补板安装于所述嵌补板预留孔内,所述嵌补板的厚度大于所述通孔边缘的厚度。通过在开孔置位增加嵌补板,使所述开孔结构在开孔位置的结构强度得到显著提高,有助于解决现有技术中开孔后在运输或者焊接时导致结构变形和受损的技术问题。
