Abstract

The invention belongs to the technical field of civil air defence equipment, and particularly discloses a civil air defence door leaf with a geometric composite structure. The civil air defence door leaf comprises a door core structure, a door leaf outer frame, an upper panel and a lower panel, the door core structure is a skeleton structure formed by continuous geometric structures, and the doorleaf outer frame, the upper panel and the lower panel are fixed to the door core structure correspondingly to form the civil air defence door leaf. According to the civil air defence door leaf with the structure, the problems that the weight of the civil air defence door leaf is large, and transporting and mounting are not convenient in the prior art can be solved.

Example Embodiment

[0048] Example one
[0049] Basic as attached Figure 1-3 Shown: a geometric composite structure civil air defense door leaf, including door core structure 1, door leaf outer frame 2, upper panel 3 and lower panel 6, door core structure 1 is a continuous geometric structure of the skeleton structure, door leaf outer frame 2. The upper panel 3 and the lower panel 6 are respectively fixed with the door core structure 1 to form a civil air defense door leaf. The geometric structures are regular triangles, squares, regular hexagons, trapezoids, rhombuses, perfect circles and ellipses. Such as Figure 4 As shown, the door core structure 1 is welded by several equilateral triangles. Such as Figure 5 As shown, the door core structure 1 is formed by welding several squares. Such as Image 6 As shown, the door core structure 1 is formed by welding several diamonds. Such as Figure 7 As shown, the door core structure 1 is formed by welding several regular hexagons. Such as Picture 9 As shown, the door core structure 1 is welded by a number of isosceles trapezoids. Such as Picture 10 As shown, the door core structure 1 is welded with several perfect circles.

Example Embodiment

[0050] Example two
[0051] Basic as attached Figure 1-3 As shown, a civil air defense door leaf with a geometric composite structure includes a door core structure 1, a door leaf outer frame 2, an upper panel 3, and a lower panel 6. The door core structure 1 is a skeleton structure composed of a continuous geometric structure, and the door leaf outer frame 2. The upper panel 3 and the lower panel 6 are respectively fixed with the door core structure 1 to form a civil air defense door leaf. The geometric structure is composed of a number of first profiled parts or a combination of several steel strips 4 and a second profiled part; the first profiled part and the second profiled part are both cold-formed profiled parts, the first profiled part It is a continuous broken line structure 5 or a continuous corrugated structure 7, the second profiled part is a continuous broken line structure 5; the steel strip 4 is a straight structure. Several first profiled parts can form a continuous geometric structure with each other, and the second profiled part combined with the steel strip 4 can also form a geometric structure.
[0052] Such as Figure 4 As shown, the door core structure 1 is composed of Picture 11 The several steel strips 4 shown are welded with the broken line structure 5 (second profiled part).
[0053] Such as Figure 5 As shown, the door core structure 1 is composed of Picture 12 The several continuous broken-line-shaped structures 5 (first profiled parts) shown are welded.
[0054] Such as Image 6 As shown, the door core structure 1 is composed of Figure 13 The several continuous broken-line-shaped structures 5 (first profiled parts) shown are welded.
[0055] Such as Figure 8 As shown, the door core structure 1 is composed of Figure 14 The several continuous broken-line-shaped structures 5 (first profiled parts) shown are welded.
[0056] Such as Picture 9 As shown, the door core structure 1 is composed of Figure 15 The several steel strips 4 shown are welded with the broken line structure 5 (second profiled part).
[0057] Such as Picture 10 As shown, the door core structure 1 is composed of Figure 16 The shown several continuous corrugated structures 7 (first profiled parts) are welded together.

Example Embodiment

[0058] Example three
[0059] A method for manufacturing a civil air defense door leaf with a geometric composite structure includes the following steps:
[0060] (1) Manufacturing geometrical pipes: prepare round pipes, which are made into geometrical pipes by cold drawing, such as regular triangles, squares, trapezoids, rhombuses, regular hexagons, regular circles or ellipses;
[0061] (2) Manufacturing geometrical structures: cutting geometrical pipes to form cylindrical geometrical structures;
[0062] (3) Manufacturing door core structure 1: Weld several geometric structures into a sheet-shaped door core structure 1 (such as Figure 4 , 5 , 6, 7, 9, 10);
[0063] (4) Manufacture the frame of the civil air defense door leaf: prepare the door leaf frame 2 and weld the prefabricated sheet-shaped door core structure 1 into the door leaf frame 2 to form the air defense door leaf frame (such as image 3 );
[0064] (5) Manufacture the preliminary civil air defense door leaf: prepare the upper panel 3 and the lower panel 6, superimpose the prefabricated air defense door frame on the lower panel 6, and weld the civil air defense door frame and the lower panel 6 from the inside; Anti-rust coating treatment, and install the built-in locking mechanism of the civil air defense door leaf; finally the upper panel 3 is welded to the upper side of the civil air defense door leaf frame to form a preliminary civil air defense door leaf (such as figure 1 , figure 2 );
[0065] (6) Install relevant accessories on the preliminary air defense door leaf, and then paint to form the final air defense door leaf.
