Embodiment 1

[0049] Basic as attached Figure 1-3 Shown: a civil air defense door leaf with a geometric composite structure, including a door core structure 1, a door leaf 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 a regular triangle, a square, a regular hexagon, a trapezoid, a rhombus, a perfect circle and an ellipse. Such as Figure 4 As shown, the door core structure 1 is welded by several regular triangles. Such as Figure 5 As shown, the door core structure 1 is welded by several squares. Such as Figure 6 As shown, the door core structure 1 is welded by several rhombuses. Such as Figure 7 As shown, the door core structure 1 is welded by several regular hexagons. Such as Figure 9 As sho...

Embodiment 2

[0051] Basic as attached Figure 1-3As shown, a civil air defense door leaf with a geometric composite structure includes a door core structure 1, a door leaf 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 several first profiled parts or a combination of several steel strips 4 and second profiled parts; both the first profiled part and the second profiled part are cold-formed profiles, and the first profiled part It is a continuous zigzag structure 5 or a continuous corrugated structure 7, the second profiled part is a continuous zigzag structure 5; the steel strip 4 is a straight line structure. Several first profiled parts can form a continuous geometric structure with each othe...

Embodiment 3

[0059] A method for manufacturing a civil air defense door leaf of a geometric composite structure, comprising the following steps:

[0060] (1) Manufacture of geometric pipes: prepare round pipes, which are made into geometric pipes by cold drawing, such as regular triangles, squares, trapezoids, rhombuses, regular hexagons, perfect circles or ovals;

[0061] (2) Manufacture the geometric structure: cutting the geometric pipe to form a cylindrical geometric structure;

[0062] (3) Manufacture door core structure 1: Weld several geometric structures into sheet-shaped door core structure 1 (such as Figure 4 , 5 , 6, 7, 9, 10);

[0063] (4) Manufacture the civil air defense door frame: prepare the door leaf frame 2, and weld the prefabricated sheet-like door core structure 1 in the door leaf frame 2 to form the civil air defense door frame (such as image 3 );

[0064] (5) Manufacture the preliminary civil air defense door: prepare the upper panel 3 and the lower panel 6, p...

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.

Description

technical field [0001] The invention belongs to the technical field of civil air defense equipment, in particular to a civil air defense door leaf with a geometric composite structure and a manufacturing method. Background technique [0002] The civil air defense project is an important place to hide personnel and materials in wartime and protect the safety of people's lives and property. It is also the most important material basis for the implementation of civil air defense. an important component. It is used to prevent the shock wave effect generated by the explosion of nuclear weapons and conventional weapons, so as to avoid casualties or equipment damage. [0003] At present, civil air defense doors commonly used in China can be divided into two types according to the material structure, one is reinforced concrete civil air defense doors, and the other is steel structure civil air defense doors. However, the material ratio of reinforced concrete civil air defense door...
