A geodesic dome is a structure with multiple very interesting properties. Apart from its original aesthetic aspect, it offers an excellent resistance to environmental weathering and a strong mechanical resistance. It is composed of wood, metal, and PVC as uprights. Discover, in this reading, the factors and materials that participate in its construction.
Factors to consider
The diameter is the main element to consider. The complexity of the dome construction and the ceiling height of the geodesic dome will be important or not depending on the diameter. Next comes the frequency. For a given diameter, it is possible to build the dome with a higher or lower density of posts and connectors. The support is also a key element in the design of a dome. Depending on the intended use, the dome must be equipped with a support system. If the dome is to be designed to act as a greenhouse, then it is up to the builders to place the dome directly on concrete pads without building a floor.
Materials involved in the construction of a dome
The construction of a geodesic dome requires several materials, including metal rods. These are primarily the steel or aluminum rods used to form the structure of the dome. They can be cut to length and bent to fit the geodesic shape. Next, connectors will be needed to secure the metal rods together at the points of intersection. These connectors are usually made of metal or plastic. Bolts and nuts will be used to attach the connectors to the metal rods. Reinforcing plates will also be used to reinforce the connection joints between the metal rods and the connectors. A tarp or covering is required. This covers the dome structure and protects it from the outside elements. Commonly used materials include PVC sheeting, silicone-coated fabric or polycarbonate. Tools such as pliers, hammers, wrenches and drills are needed to assemble the geodesic dome structure.
