A dome home is a type of architectural element, with windows and doors like any other house, except in the shape of a spherical ellipsoid or sphere like a hollow upper half of a sphere. A dome of dome home is a hemispherical thin-shell structured based on polyhedrons. House Domes are also constructed with a lightweight aluminum framework, either welded or bolted together or connected with more flexible nodal point connections. These home domes are usually clad with glass, held in place with PVC coping. The dome can seal the coping with silicone to make it watertight. Some designs also allow for insulated panels or double glazing to be fixed in the framework. It will enable a fully habitable building to be formed.
Who invented Dome?
Dome construction is a relatively new invention. The Pantheon in Rome has rebuilt around 125 AD and is one of the oldest domes. In order to support the weight of heavy construction materials in the early domes, the walls became very thick and the top roof of the dome became thinner. In the case of the Roman Pantheon, there are naked eyes at the top of the dome.
In 1919, German engineer Dr. Walther Bauersfeld took the lead in combining triangles with architectural arches.
R. Buckminster Fuller conceived and promoted the concept of a geodesic dome as a home. Fuller’s first geodesic dome was issued in 1954. In 1967, his design was exhibited globally. He said that the dome will pay for itself within ten years. On the occasion of the 50th anniversary of obtaining the geodesic dome patent, R. Buckminster Fuller was commemorated on a US stamp in 2004. His patent index can be found at Buckminster Fuller Institute.
This triangle continues to be used as a means to increase the height of the building, as evidenced by many skyscrapers, including the World Trade Center in New York City.
There are some types of dome houses distinguished by their shell.
Geodesic Dome Homes
The geodesic dome is a spherical frame structure composed of a triangular network. The connected triangles create a strong and elegant self-supporting frame. The geodesic dome can be called the “less is more” form of expression, as a minimum geometric arrangement of the construction materials ensures both strong and light design – especially when the frame with ETFE and other modern siding materials when covered. The design allows a huge interior space, free of columns or other support.
The geodesic dome house has a pillar with a drilled width. The stainless steel band locks the hole of the pillar to the steel pipe. In this way, the pillar can be cut to the exact length required. Then nail the outer plywood triangle to the pillar. The dome is wrapped with several layers of tar paper from bottom to top, sprinkled with water, and finished with tiles.
The geodesic dome also has many advantages. They have aerodynamic properties, keep well in strong winds, and are especially suitable for solar heating.
Although there are many geodesic domes around the world, most of which consist of public and corporate buildings, they have never been residential buildings for many reasons.
Over the years, many problems have been solved by improving the structure, and now there are easy-to-assemble tool kits that people can use to build their own geodesic domes at a much lower cost than traditional houses. However, they are still uncommon as residential structures. There are many famous geodesic domes in the world, including the Spaceship Earth of Walt Disney in Epcot, Orlando, Florida; Dream Entertainment Center and Multi-Function Arena in Japan; and the Eden Project Environmental Complex in Cornwall, England.
Concrete Dome Homes
Concrete dome homes generally start with a steel framework dome. Domes are wrapped with chicken wire and a wire screen for reinforcement. The chicken wire and screen are ties with wire ties to the framework. A coat of material is molded or then sprayed onto the frame of the dome house. Tests can be performed with small squares to achieve the correct consistency of plastic or concrete. Generally, many coats are necessary on the inside and the outside. The last step is to saturate polyester or concrete domes with a thin layer of epoxy compound to the shed-water.
This construction is well-suited to domes because no place allows water to pool on the concrete and leak through. The bolts are within raised receptacles covered with little concrete internal steel as to shed water. The triangles overlap to shed water. The metal elements, joints, and steel elements remain dry, which prevents frosting and corrosion damage. The concrete resists sun and weathering. Some form of internal flashing or caulking over the joints to avoid drafts.
Inflatable Concrete Dome Homes
Due to its special shape, the dome can be safely classified as a work of art. Inflatable concrete dome houses are superior to traditional cubic buildings in all aspects.
Ideally, its spherical shape ensures uniform load distribution on the structure. No matter which part of the structure is mechanically acted upon, it will be effectively distributed throughout the array. Due to the balanced placement of stiffeners and pivots, this performance is particularly prominent in houses built on the basis of triangular frames. For areas with an unstable climate, hemispherical houses are the most suitable: due to their streamlined shape, they can withstand wind gusts up to 230 km/h.
Tiny Dome Homes
They look small, but the image is fascinating: despite their compact appearance, these houses are very spacious. It may give the impression of design fragility and unreliability, but the attractive appearance, in this case, does not mean that there is a technical defect at all.
The main features of the Tiny Dome Homes:
- Designed to withstand the worst weather. They are equipped with high-quality aluminum and 5mm tempered glass, thus ensuring the weatherproof structure of the elements. They can withstand temperatures from -40 degrees Celsius to +80 degrees Celsius.
- Tiny glass dome made of corrosion-resistant and anti-corrosion materials, which means it requires minimal maintenance.
- It is ideal for outdoor spaces, such as the backyard, terrace simply, even the roof, and easy to install.
- Numerous accessories and equipment make the structure as comfortable as a permanent building.
- Tiny glass-domed houses provide 100% of the available space, and for a variety of purposes – relax, do yoga, entertainment, artist’s studio, or even create a perfect environment.
Modular Dome Homes
There are some differences in Modular dome homes:
- The fort does not require additional concrete work.
- The prefabricated structure of the prefabricated block can be disassembled and moved. Generally, the use of such houses is seasonal.
- The technology differs in the arrangement of door and window openings.
- In contrast to templates, block buildings are usually fully equipped (including doors, windows, ventilation systems, etc.).
- The use of fixed templates limits the variety of shapes and sizes to some extent.
As for the construction technique, it is very simple. After the structural elements are delivered to the construction site, they are classified and divided into several groups. The first is the basement level: it is fixed to the basement by brackets or anchors. Behind it is the structure of the dome. The shape and size of the blocks are the same. They are fixed to each other by locking or overhead mechanical connections.
