Detailed description of the invention

Geometry solid figure is combined by 12 same components; Each assembly by parts 1 and parts 2 totally two component combinations form; Adopt the positive broken line of front represented by dashed line doubling, solid line adds the fold line that circle represents reverse side doubling, and ghost line adds arrow and represents insertion line, and the dotted portion inserting line represents and inserts part in interlayer, and the bold portion inserting line represents and do not insert sandwich portion;

Get square of paper, four paper angles are pointed to up and down, are parts 1; As Fig. 1;

Get grow crosswise vertical wide be 2: 1 rectangular paper, the length of side of the wide and parts 1 of rectangular paper is isometric; Do longitudinally positive broken line, rectangular paper being divided equally is two congruent squares; As Fig. 2;

Be affixed according to longitudinal positive folding line, form folding square, folding foursquare is enclosed edge, and other three limit is the limit having interlayer opening, i.e. opening edge, is parts 2; As Fig. 3;

Parts 1 are placed on parts 2, form polygon-octagonal; The middle part of polygon-octagonal forms octagon, and be eight congruent right angled isosceles triangles and little triangle outside octagon, four little triangles of parts 1 are the little triangles of parts 1, and four little triangles of parts 2 are the little triangles of parts 2; Base fold line is done on the little leg-of-mutton base of parts 1; As Fig. 4;

According to base fold line by little for parts 1 triangle collapse, parts 2 enclosed edge side and be affixed on the bottom surface of parts 2 mutually with the little triangle collapse of parts 1 of the opening edge side of its opposite side, other two little triangles of parts 1 fold in the interlayer of parts 2 opening edge respectively, and polygon-octagonal forms the congruence square with parts 2 congruence; Congruent square does two diagonal fold lines; Article two, diagonal fold line intersects at center intersection point; The vertical positive broken line perpendicular to parts 2 enclosed edge is done by center intersection point; As Fig. 5;

According to diagonal fold line, the positive folding line of vertical line, be not affixed, assembly, assembly is in being summit with center intersection point, having the three-dimensional shape of two large flat square isosceles triangles, four facet right angled isosceles triangles; The base of large flat square isosceles triangle is parts 2 opening edges, and the base of facet right angled isosceles triangle is that the center intersection point of diagonal fold line is to congruent one section, foursquare angle; Adjacent large flat square isosceles triangle and facet right angled isosceles triangle form folding triangle, and the little triangle of parts 2 of folding triangle forms the little triangle of rugosity, the little triangle of the insertion for assembly; The little leg-of-mutton base of parts 2 forms two Sandwich openings, namely assembly be inserted into opening; As Fig. 6;

The insertion method of two assemblies: that little for the insertion of assembly triangle is inserted another assembly is inserted in the interlayer of opening, the plane of the large flat square isosceles triangle of insertion side keeps in one plane with the plane of the large flat square isosceles triangle of the side of being inserted into, and also namely the plane of the facet right angled isosceles triangle of the side of insertion keeps in one plane with the plane of the facet right angled isosceles triangle of the side of being inserted into; As Fig. 7; Namely the opening that is inserted into inserting little triangle one side completes grafting with the opening coincidence that is inserted into being inserted into a side;

Four folding triangles of each assembly respectively with each folding triangle grafting in this way of another four assemblies; Four after grafting large flat square isosceles triangles form a square-shaped planar, and three facet right angled isosceles triangles form a depression triangle; 12 the pluggable Cheng Youliu of assembly plane squares, eight leg-of-mutton geometry solid figures of depression; As Fig. 8.
