Abstract:
1. An improved, yurt-type, generally round in plan view, rigid-wall and roof modular, lightweight enclosed structure having an interior useful space and a single exterior wall, comprising in assembled use combination: a) a plurality of generally identical rectangular wall panels having a horizontal width and a vertical height, said panels are made of self-standing, light weight, water-resistant plastic sheet having a cellular core defined between smooth exterior and interior planar surfaces, said panels having a plurality of fold lines to define marginal flaps when folded either inwardly toward the interior or outwardly toward the exterior of said yurt structure to form a wall panel module: b) a plurality of identical generally triangular roof panels having a lateral base width substantially equal to said horizontal width of said wall panel module sheet, and a radial length corresponding to said yurt, said panels are made of self-standing plastic sheeting having a cellular core defined between smooth exterior and interior planar surfaces, said panels having a plurality of fold lines to define marginal flaps when folded either downwardly toward the interior or upwardly toward the exterior of said yurt structure to form a roof panel module: c) a vertically oriented vent structure including a cylindrical pipe having a first interior end and a second exterior end and a flange secured medially of said ends to the exterior of said pipe, said pipe and said flange together forming a compression ring assembly; d) said plurality of wall modules comprising a first, wall module and a last wall module disposed in a generally circular array as seen in plan view with a space between said first wall module and said last wall module to serve as an entry, with said ground flaps extended outwardly, and said vertical wall ribs compressively secured together with fasteners passing through said rib sheet material to seal adjacent wall modules along adjacent said vertical marginal flap fold lines; e) said plurality of triangular roof modules secured together along their common interleaved radial roof rafters and placed atop said plurality of wall modules: f) so that together said compression ring, said radial rafters and said fastening of said eave flaps to said side wall module panels form a strong, light weight, water proof, semi-permanent but robust, modular, load bearing yurt-type structure the panels of which comprising an entire yurt structure are man-portable and field erectable by hand.
