The production method comprises fetching diamond paper and producing obtuse angle diagonal folding lines, connecting line front folding lines, cut lines and the like; enabling the portions below the connecting line front folding lines to be folded and pasted upward according to the connecting line front folding lines; folding the right side portions of coincidence front folding lines to the left side to achieve pasting and coincidence according to the coincidence front folding lines to achieve the assemblies; inserting a first angle of the first assembly into a third angle interlayer of the second assembly and inserting the second assembly into the third assembly and inserting the third assembly into the first assembly in the same way; inserting the first angles of the three assemblies into the second angles of the three assemblies respectively to achieve coincidence and obtaining the three-assembly equilateral triangle paper sheet body. According to the production method of the three-assembly equilateral triangle paper sheet body, the design is skillful and the operation is simple; the steps are regular and the insertion connection is easy; the locking function after the insertion connection is significant and the three assemblies are not easy to fall off; three colors or three patterns can be utilized to configure the three assemblies so as to increase the ornamental value of the work.

Description

The preparation method of three assembly equilateral triangle plates

Technical field

The present invention relates to a kind of preparation method of plane geometry body, especially a kind of preparation method of equilateral triangle.

Background technology

At present, the equilateral triangle plates of known three assembly combinations are pegged graft firm not, and three assemblies are easily discrete.

Summary of the invention

Firm not for the equilateral triangle plates grafting that overcomes existing three assembly combinations, three assemblies are discrete deficiency easily, the invention provides a kind of preparation method of three assembly equilateral triangle plates.

The technical solution adopted for the present invention to solve the technical problems is: by three same components, the first assembly, the second assembly and the 3rd assembly have combined three assembly equilateral triangle plates;

The preparation method of assembly: get rhombus paper, two obtuse angles are up and down, and two acute angles, in left and right, adopt dotted line to mean the positive broken line of positive doubling, and solid line adds the fold line that circle means the reverse side doubling; Do obtuse angle diagonal fold line, rhombus paper is divided into to the equilateral triangle of two congruences in left and right; Do the positive broken line of line between the mid point of two equilateral triangles, with the positive broken line of obtuse angle diagonal, intersect at intersection point in paper; On obtuse angle diagonal fold line, in paper, the supreme obtuse angle of intersection point apex portion is the positive broken line part of obtuse angle diagonal, and in paper, intersection point to lower obtuse angle apex portion is obtuse angle diagonal fold line part; Mid point by equilateral triangle does to the following mid point deflection rhombus paper acute angle direction of equilateral triangle the cut line that paper is cut apart with a knife or scissors, and the acute angle angle that cut line and rhombus paper acute angle diagonal form is less than 60 degree, is greater than 30 degree;

According to the positive broken line of line, part below it is upwards folded and is affixed, diagonal positive broken line in obtuse angle is for overlapping positive broken line;

According to overlapping positive broken line, to overlap positive broken line right part is folded to the left side and is affixed coincidence, it is first jiao that two acute angles of rhombus paper overlap, upper obtuse angle forms 60 degree angles with dissection, it is second jiao, the positive broken line two parts of line that intersection point is boundary in paper of take overlap, and overlap positive broken line formation an angle of 90 degrees, are triangle; The first assembly completes;

The second assembly, the 3rd assembly are made in this way;

The combined method of three assembly equilateral triangle plates: by first jiao of the first assembly triangle interlayer that inserts the second assembly, in the triangle interlayer that first jiao of the second assembly inserts the 3rd assembly, first jiao of the 3rd assembly inserts in the triangle interlayer of the first assembly;

First jiao of three assemblies continues respectively to be inserted to second jiao of being inserted into assembly and overlaps with it, and the mid point of the equilateral triangle of three assemblies coincides, three assembly equilateral triangle plates.

The invention has the beneficial effects as follows, design ingenious, simple to operate; The step rule, peg graft easily; Lock function after grafting is remarkable, difficult drop-off; Three assemblies can be by three kinds of colors or three pattern arrangement, to increase the sight of works.

The specific embodiment

By three same components, the first assembly, the second assembly and the 3rd assembly have combined three assembly equilateral triangle plates;

The preparation method of assembly: get rhombus paper, two obtuse angles are up and down, and two acute angles, in left and right, adopt dotted line to mean the positive broken line of positive doubling, and solid line adds the fold line that circle means the reverse side doubling; Do obtuse angle diagonal fold line, rhombus paper is divided into to the equilateral triangle of two congruences in left and right; Do the positive broken line of line between the mid point of two equilateral triangles, with the positive broken line of obtuse angle diagonal, intersect at intersection point in paper; On obtuse angle diagonal fold line, in paper, the supreme obtuse angle of intersection point apex portion is the positive broken line part of obtuse angle diagonal, and in paper, intersection point to lower obtuse angle apex portion is obtuse angle diagonal fold line part; Mid point by equilateral triangle does to the following mid point deflection rhombus paper acute angle direction of equilateral triangle the cut line that paper is cut apart with a knife or scissors, and the acute angle angle that cut line and rhombus paper acute angle diagonal form is less than 60 degree, is greater than 30 degree; As Fig. 1;

According to the positive broken line of line, part below it is upwards folded and is affixed, diagonal positive broken line in obtuse angle is for overlapping positive broken line; As Fig. 2;

According to overlapping positive broken line, to overlap positive broken line right part is folded to the left side and is affixed coincidence, it is first jiao that two acute angles of rhombus paper overlap, upper obtuse angle forms 60 degree angles with dissection, it is second jiao, the positive broken line two parts of line that intersection point is boundary in paper of take overlap, and overlap positive broken line formation an angle of 90 degrees, are triangle; The first assembly completes; As Fig. 3;

The second assembly, the 3rd assembly are made in this way;

The combined method of three assembly equilateral triangle plates: by first jiao of the first assembly triangle interlayer that inserts the second assembly, in the triangle interlayer that first jiao of the second assembly inserts the 3rd assembly, first jiao of the 3rd assembly inserts in the triangle interlayer of the first assembly; As Fig. 4;

First jiao of three assemblies continues respectively to be inserted to second jiao of being inserted into assembly and overlaps with it, and the mid point of the equilateral triangle of three assemblies coincides, three assembly equilateral triangle plates; As Fig. 5.
