New construction technology that inflates structures could make fast and cheap D printing viable. We've already heard that D printed concrete buildings can be built quickly and easily, but could there be an even faster and easier method? According to American inventor Alex Bell, there certainly is, and it involves inflating buildings and then pumping concrete into them. His new construction technique, dubbed Inflatable Flexible Factory Formwork (IFFF) , has been commercialized through his new New York-based company, Automatic Construction . Functioning. The process begins with a truck carrying a rolled-up PVC (polyvinyl chloride) fabric “formwork” to the construction site.
That flexible form is a giant version of a rolled and deflated camping mattress. Once the formwork is in place, air pumps are used to inflate its walls and roof. This causes it to rise, adopting the three-dimensional shape of the finished structure. Locally sourced wet concrete is then pumped into the walls and ceiling of the formwork, displacing the air inside. Once the concrete has set, the BTC Number Data result is a solid concrete shell. The formwork is not removed from the shell, as it now serves as a waterproof and airtight barrier and, therefore, energy saving. Elements such as doors, windows, interior drywall, and exterior siding are then added. In the prototype structures created so far, in-situ rebar reinforcements have also been added.
However, Bell says he ultimately hopes to have rebar, tension cables and other reinforcing elements pre-installed in the forms. But how quickly do buildings go up? For m and m prototypes , inflation took between seven and ten minutes with air. Then the concrete pump filled them in h. Including labor, ours only cost $ per square foot. Bell's team now sells homes directly to clients in New York's Hudson Valley, with one project underway and two others signed. He says his company has also signed a contract with a “large commercial contractor” to deliver a structure, and has signed another contract to deliver a culvert to an infrastructure contractor. In addition to homes, commercial buildings, and infrastructure-related projects, other anticipated applications of IFFF technology include swimming pool foundations, rapidly deployable military structures, and perhaps even oneday skyscrapers, or structures on Mars for of the astronauts.
