Embodiment Construction

[0025] Triangular parts plugged into a three-dimensional shape, which is formed by plugging together 20 identical parts from part 1, part 2...part 20; the dotted line is used to indicate the positive fold line of the front half, that is, when folding, the front side of the paper and the front side are attached; the solid line The circle indicates the anti-folding line of reverse-folding, that is, when folding, the reverse side of the paper and the reverse side stick together; the arrow line indicates the indicator line of the insertion direction, the dotted part of the arrow line indicates the inserted part, and the solid line part of the arrow line indicates that it is not inserted part;

[0026] Take a rectangular paper that is horizontally long and vertically wide, and make three vertical fold lines perpendicular to the long side of the rectangular paper, and divide the rectangular paper into four small rectangles, namely, from left to right, the first small rectangle, the s...

Abstract

The invention relates to a three-dimensional form with triangular parts plugged in, and relates to a manufacturing method of the three-dimensional form. It is formed by plugging 20 identical parts; take rectangular paper, divide it into four congruent small rectangles, the ratio of length to width of the small rectangles is 1:0.5774, and fold them into a three-dimensional shape surrounded by three sides according to the vertical folding line; The folding line is folded into a polygonal shape; according to the connecting positive folding line and the angle bisector, it is folded into a part with a folded insertion part and a folded insertion opening; a folded insertion part of part 1 is inserted into a folded part of part 2 to be inserted into the opening; if it is plugged in , Insert part 2 into part 3, part 3 into part 4, part 4 into part 5, part 5 into part 1, and then form a pentagonal assembly; if it is plugged in, 20 parts will be plugged into 12 pentagons The triangular parts of the triangular assembly are plugged into a three-dimensional shape; the concept is ingenious and the design is novel; the parts are easy to make and the combination is simple; the shape is beautiful and generous, and it is strong and firm.

Description

technical field [0001] The invention relates to a method for making a three-dimensional shape, in particular to a method for making a plug-in three-dimensional shape. Background technique [0002] At present, the known plug-in three-dimensional triangular parts are composed of two isosceles triangles, and the combination of the two triangles is not tight and easily deformed, resulting in weak plug-in. Contents of the invention [0003] In order to overcome the problem that the existing three-dimensional triangular component for plugging is composed of two isosceles triangles, and the combination of the two triangles is not tight, and it is easy to deform, resulting in an insecure plug. The invention provides a triangular component plug Connect the three-dimensional shape. [0004] The technical solution adopted by the present invention to solve the technical problem is: the triangular parts are plugged into a three-dimensional shape, which is formed by plugging together 2...
