D concrete printing (DCP) technology is already known to be more efficient for building construction. Now, a new type of DCP is even better, resulting in walls that are % lighter than conventional ones.
In most DCP construction jobs, a robotic extruder nozzle moves in straight lines parallel to the ground, building wall molds one horizontal layer at a time. Once the hollow centers of those molds have been filled with rebar and more concrete, the walls are finished.
According to Dr. Mania Aghaei Meibodi Phone Number List and his colleagues at the DART (Digital Architecture Research Technologies) Laboratory at the University of Michigan, these facilities use more concrete than necessary and limit the architectural features of the buildings to fairly simple shapes. That is where the Shell Wall system intends to come in.
It begins with the creation of a computer model of the structure, which is based on the most efficient distribution of the material needed to provide the required strength in each part of the building. In other words, materials are not included where they are not necessary.
Guided by that model, the printing nozzle then constructs layered wall elements consisting of curved vertical structural ribs with finer curved membranes spanning the spaces between them. The concrete layers are deposited in a non-planar manner, that is, not necessarily parallel to the ground. And as each element is built, vertical sections of rebar are inserted inside the hollow ribs, while thermal insulation is placed inside the hollow membranes.
Small-scale testing indicates that, compared to traditional walls of the same size constructed from solid concrete, Shell Wall elements offer a % weight reduction with the same structural strength. Full-scale tests of this technology on real construction sites are now being planned.
