Description

A lunar honeycomb-shaped assembled building component

Technical field: The present invention relates to a lunar honeycomb-shaped prefabricated building component, which is a standardized, modular honeycomb-like structured building component produced on the lunar surface through prefabricated building construction technology. Its characteristic is that the component is a regular hexagonal prism structure, and the material of the component is fiber-reinforced lunar soil concrete, which is prefabricated by 3D printing or in a prefabricated building production factory.

Background Art

With the continuous successful launch of the "Chang'e" series of lunar probes, it is no longer a dream for Chinese astronauts to land on the moon. How to quickly and high-quality build houses on the moon has become an urgent technical problem to be solved, because the surface of the moon is ultra-high vacuum, 127℃ during the day and -183℃ at night. It is impossible to build houses in this environment by masonry or cast-in-place concrete according to the construction technology on Earth, because masonry or cast-in-place concrete requires on-site construction temperature conditions between 5℃ and 30℃. Therefore, 3D printing or prefabricated production methods must be adopted. At this time, the reasonable selection of building materials and building structures is crucial.

At present, due to the limited carrying capacity of spacecraft, it is impossible to transport a large amount of building materials from the earth. Therefore, it is necessary to make full use of the in-situ materials on the lunar surface for engineering construction. The lunar soil that is everywhere on the lunar surface has become the first choice. Lunar soil is widely distributed on the lunar surface. It is composed of rock fragments, powders and impact molten glass, with an average particle size of less than 0.2 mm. The main mineral components are pyroxene, olivine, plagioclase, ilmenite, basalt, etc. The lunar soil is melted and solidified by laser, microwave, solar energy, etc., or solidified by chemical reaction, and the construction materials are obtained by mixing the lunar soil with cementing materials, and a small amount of high-performance fibers or continuous long fibers are added. The tensile strength and fracture toughness of the material can be significantly improved. Through these technical means, fiber-reinforced lunar soil concrete that meets the requirements of prefabricated buildings can be processed.

In the closed lunar prefabricated building production factory, the prefabricated building components required for standardized lunar buildings can be produced quickly and in large quantities according to the prefabricated component design drawings. The honeycomb-shaped prefabricated building components are easier to process, produce and transport than the spherical ones in terms of structural form. Compared with cubes and rectangular blocks, they have advantages in structural safety and space utilization. Therefore, choosing honeycomb-shaped prefabricated building components to build houses on the moon is a better option.

Summary of the invention

The purpose of the present invention is to provide a lunar honeycomb prefabricated building component, which is produced by 3D printing or prefabrication in a prefabricated building production factory using fiber-reinforced lunar soil concrete that can be produced on the moon. The component is a honeycomb regular hexagonal prism structure, in which two faces are regular hexagons and six sides are squares or rectangles. The component can be installed and used independently or two or more components of the same size can be connected and spliced to form a larger building body, and there are channels connecting them inside.

To solve this problem, we should try to use the fiber-reinforced lunar soil concrete made from lunar soil, and use 3D printing or prefabrication in prefabricated building production factories to produce the lunar honeycomb prefabricated building components in the present invention. Except for a few fiber materials that need to be transported from the earth, the rest should try to use the in-situ materials on the lunar surface - lunar soil.

The building components in the present invention are regular hexagonal prism enclosure structures with thermal insulation, heat insulation and sound insulation functions. They can be integrated by continuous 3D printing of fiber-reinforced lunar soil concrete, or assembled as a whole by producing the eight wall panels of the regular hexagonal prism enclosure structure in an assembled construction factory. The reserved openings at the door and window positions are installed in the later stages of the assembly work.

The building component in the present invention is a regular hexagonal prism enclosure structure with thermal insulation, heat insulation and sound insulation functions, and its appearance dimensions are as follows: a regular hexagonal prism structure, including two regular hexagonal faces and six rectangular or square edges, that is, the two regular hexagonal faces always maintain a vertical angle (maintaining a 90-degree angle with the horizontal plane), and two symmetrically distributed edges maintain a 90-degree angle with the horizontal plane.

Two component pipe groove spaces are designed at the top and bottom of the building components in the present invention for laying pipes for water, electricity, HVAC systems and smart home systems. The prefabricated house composed of the structure also includes a component external connection management system, a prefabricated door and window system, an interior decoration system, a water and electricity pipe system, a HVAC system, a smart home system, etc.

The building components in the present invention can be installed and used independently, and can be used as an independent residence, living room or studio, and its facade is connected to the lunar honeycomb integrated pipeline corridor through an intelligent sliding door; two or more building components of the same size can also be connected and spliced to form a larger building body, in this case through two regular hexagonal faces.

The beneficial effect of the present invention is that it provides a type of building structure suitable for human habitation and work on the moon, which is safe, durable, and easy to build using local materials. Since the building component is in the shape of a regular hexagonal prism, it can be connected with building components of the same size in a flexible manner on two regular hexagonal faces and two side faces, which is very suitable for building residential and scientific research office buildings with different functional requirements in limited space such as the lunar lava tunnel.

The present invention is applicable to buildings and building complexes in lunar lava tunnels, and is also applicable to buildings and building complexes on the earth's land surface and in karst caves.
