Abstract
An emergency shelter includes a domed foam structure that is constructed on-site or at a remote location from foam that can be mixed on-site. The structure can be made on-site by spraying foam in a flowable state in a predetermined pattern to build up walls to form a dome. The foam can be sprayed, for example, in a substantially helical pattern from a centrally located spray nozzle that is rotated to deposit a finite-thickness increment of foam over a time period sufficient that, by the time the nozzle reaches a previously sprayed area, the foam already deposited has had time to cure.
Claims22
A method of forming a shelter structure in situ comprising the steps of:
- providing a source of water at a site on which it is desired to erect a shelter structure;
- mixing foam material precursors with the provided water to form a structural foam;
- spraying the formed structural foam in a plurality of layers in an upwardly extending helical pattern of decreasing diameter on the site to free form a domed structure having a foam wall defining an interior space;
- and
- cutting through the foam wall to form a passage into the interior space.
A method of forming a shelter structure for transport to a remote site comprising the steps of:
- mixing foam material precursors to form a structural foam;
- spraying the formed structural foam in a plurality of layers in an upwardly extending helical pattern of decreasing diameter on the site to free form a domed structure having a foam wall defining an interior space;
- and
- transporting the domed structure to a remote site.
A method of forming a shelter structure in situ comprising the steps of:
- providing a source of water at a site on which it is desired to erect a shelter structure;
- mixing foam material precursors with the provided water to form a structural foam;
- spraying the formed structural foam in a plurality of layers in an upwardly extending substantially rectangular pattern on the site to free form four foam walls, and then in a pyramidal pattern atop the foam walls to free form a roof thereon, the walls and the roof defining an interior space;
- and
- cutting through the foam wall to form a passage into the interior space.
