Abstract

The invention discloses a splicing geometry solid figure, and relates to a method for manufacturing the solid figure. The splicing geometry solid figure is formed by combining a first component, a second component, a third component, a fourth component, a fifth component and a sixth component. The method comprises the steps that square paper is taken and folded into two congruent isosceles trapezoid cross components through a diagonal folding line, an indicating line folding line, a first reverse fold line, a second reverse fold line, a second cross point, a just fold line and the like; one trapezoid inner square of the first component and one trapezoid inner square of the second component are attached, and cross points of lower bottoms of the two components coincide, and the attached trapezoid inner squares of the two components coincide; adjacent trapezoid inner triangles of the attached trapezoid inner squares of the two components are folded into an interlayer of the trapezoid inner squares; and if splicing exists, the six components are combined into the splicing geometry solid figure. The square paper is used for manufacturing the components, the folding lines are clear and concise; the components are easy to manufacture and easy to combine; and the splicing geometry solid figure is high in modeling geometry stereo feeling

Description

Grafting solid solid figure

Technical field

The present invention relates to a kind of preparation method of solid, especially a kind of preparation method of grafting solid.

Background technology

At present, in the preparation method of known solid, it is many that design complexity makes also complicated case, and it is few that simplicity of design makes also simple case.

Summary of the invention

In order to overcome in the preparation method of existing solid, it is many that design complexity makes also complicated case, and simplicity of design makes the deficiency that also simple case is few, the invention provides a kind of preparation method of grafting solid solid figure.

The technical solution adopted for the present invention to solve the technical problems is: grafting solid solid figure is by parts 1, parts 2 ... parts 6 totally six same parts combine;

Get square of paper, do two diagonal fold line, intersect at square of paper central point; Doing three transverse line, is from top to bottom upper transverse line, middle transverse line, lower transverse line; Make three longitudinal folding lines, be from left to right left longitudinal folding line, in longitudinal folding line, right longitudinal folding line; Article three, square of paper is divided into 16 congruent little squares by transverse line and three longitudinal folding lines; Upper and lower transverse line and left and right longitudinal folding line intersect at the first intersection point between two; Middle transverse line, in longitudinal folding line respectively with left and right longitudinal folding line with upper and lowerly laterally foldedly intersect at the second intersection point;

On diagonal fold line, between two the first intersection points, part is the positive broken line of diagonal, and between paper angle to the first nearest intersection point, part is diagonal fold line;

In three transverse line and three longitudinal folding lines, between two the first intersection points on every bar fold line, part is the first fold line;

In upper and lower transverse line and left and right longitudinal folding line, the first intersection point to nearest trimming part is index line fold line;

Middle transverse line and on longitudinal folding line, between two the second intersection points on every bar fold line, part is the second fold line, and the second intersection point to nearest trimming part is positive broken line in being;

According to the positive broken line of diagonal, diagonal fold line, the first fold line, the second fold line, in positive folding line, in four, positive broken line overlaps is four line coincidence lines, four the second intersection points overlap, and adjacent two index line fold lines overlap as coincidence index line fold line, parts; It is cross-shaped that parts are two congruent isosceles trapezoids, and on parts, plane is that the upper base of two isosceles trapezoids intersects, in dissection cross-shaped; Parts lower plane is the intersection of going to the bottom of two isosceles trapezoids, and square of paper central point is crosspoint of going to the bottom; With four line coincidence lines for boundary, parts are divided into four congruent right-angled trapezium; Right-angled trapezium is with coincidence index line fold line for boundary, and square and trapezoidal interior triangular point in echelon, be inserted into part, insertion portion when trapezoidal interior triangular is parts grafting when trapezoidal interior square is parts grafting;

The mutual grafting of two parts: fitted by a trapezoidal interior square of parts 1 trapezoidal interior square and parts 2, the crosspoint of going to the bottom of two parts overlaps, two parts are affixed trapezoidal interior foursquare first intersection point and overlap;

The adjacent trapezoidal interior triangular of trapezoidal interior square that is affixed of two parts is folded in the trapezoidal interior foursquare interlayer of the other side respectively, insertion portion by parts 1 folds in the interlayer being inserted into part of parts 2, and the insertion portion of parts 2 folds in the interlayer being inserted into part of parts 1;

Grafting in this way, namely six parts are combined into grafting solid solid figure.

The invention has the beneficial effects as follows, square of paper makes parts, and fold line is concisely clear; Parts make simple, and combination easily; Moulding geometry third dimension is very strong.

Detailed description of the invention

Grafting solid solid figure is by parts 1, parts 2 ... parts 6 totally six same parts combine; Adopt the positive broken line of front represented by dashed line doubling, when namely folding, recto and vis-a-vis fold; Solid line adds the fold line that circle represents reverse side doubling, and when namely folding, the reverse side of paper is relative with reverse side folding; Solid line is added some points expression index line;

Middle transverse line and on longitudinal folding line, between two the second intersection points on every bar fold line, part is the second fold line, and the second intersection point to nearest trimming part is positive broken line in being; As Fig. 1;

According to the positive broken line of diagonal, diagonal fold line, the first fold line, the second fold line, in positive folding line, in four, positive broken line overlaps is four line coincidence lines, four the second intersection points overlap, and adjacent two index line fold lines overlap as coincidence index line fold line, parts; It is cross-shaped that parts are two congruent isosceles trapezoids, and on parts, plane is that the upper base of two isosceles trapezoids intersects, in dissection cross-shaped; Parts lower plane is the intersection of going to the bottom of two isosceles trapezoids, and square of paper central point is crosspoint of going to the bottom; With four line coincidence lines for boundary, parts are divided into four congruent right-angled trapezium; Right-angled trapezium is with coincidence index line fold line for boundary, and square and trapezoidal interior triangular point in echelon, be inserted into part, insertion portion when trapezoidal interior triangular is parts grafting when trapezoidal interior square is parts grafting; As Fig. 2;

The mutual grafting of two parts: fitted by a trapezoidal interior square of parts 1 trapezoidal interior square and parts 2, the crosspoint of going to the bottom of two parts overlaps, two parts are affixed trapezoidal interior foursquare first intersection point and overlap; As Fig. 3;

The adjacent trapezoidal interior triangular of trapezoidal interior square that is affixed of two parts is folded in the trapezoidal interior foursquare interlayer of the other side respectively, insertion portion by parts 1 folds in the interlayer being inserted into part of parts 2, and the insertion portion of parts 2 folds in the interlayer being inserted into part of parts 1; As Fig. 4;

Grafting in this way, namely six parts are combined into grafting solid solid figure; As Fig. 5.
