Problems solved by technology

[0003] At present, the plate seam arrangement of the structure below the upper circle is difficult to process, difficult to install, and the utilization rate is not high. When it is above the tangent point line, it is necessary to add an additional section of starting arc. Therefore, the present invention proposes a method for dividing and lofting structural slab seams below the upper circle to solve the problems existing in the prior art.

Abstract

The invention provides an upper-circle and lower-square structure slab joint dividing and lofting method. The method comprises the following steps: firstly, an upper-circle and lower-square three-dimensional CAD model is established; 2, plate thickness is set in the model, and plate joints are divided; and 3, a production design slab joint is arranged in the model, and then three-dimensional CAD model data is input into modeling software to complete solid modeling and part lofting and unfolding. According to the upper-circle and lower-square structure slab joint division and lofting method, the slab joints are arranged in the triangular flat plate defined by the upper-circle and lower-square tangent point lines, the flat plate serves as an edge starting arc part when a curved surface is machined, the machining difficulty is lowered, and material loss is reduced. Meanwhile, by means of the plate seam arrangement mode, sharp corner parts can be avoided, and the situation that subsequent welding seams are overlapped is avoided; the overall shape is square, and the material utilization rate can be effectively increased; and on-site positioning installation is facilitated, and the installation difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of base structure plate seam division design, in particular to a method for dividing and lofting structural plate seams with an upper circle and a lower structure. Background technique [0002] The bottom of the upper circle is a base structure that is often used on ships. The upper circle below the upper circle is combined with the rotating body of the crane structure, and the lower part is the structural alignment with the deck surface, so as to achieve effective transmission of force. ; [0003] At present, the plate seam arrangement of the structure below the upper circle is difficult to process, difficult to install, and the utilization rate is not high. When it is above the tangent line, an additional starting arc needs to be added. Therefore, the present invention proposes a method for dividing and lofting structural slab seams below the upper circle to solve the problems in the prior art. Contents...
