Crown Shaped beautiful wooden house
A traditional yurt (from the Turkic languages) or ger (Mongolian) is a portable, round tent covered with skins or felt and used as a dwelling by nomads in the steppes of Central Asia. The structure comprises an angled assembly or latticework of pieces of wood or bamboo for walls, a door frame, ribs (poles, rafters), and a wheel (crown, compression ring) possibly steam-bent. The roof structure is often self-supporting, but large yurts may have interior posts supporting the crown. The top of the wall of self-supporting yurts is prevented from spreading by means of a tension band which opposes the force of the roof ribs. Modern yurts may be permanently built on a wooden platform; they may use modern materials such as steam-bent wooden framing or metal framing, canvas or tarpaulin, Plexiglas dome, wire rope, or radiant insulation.
Traditional yurts consist of an expanding wooden circular frame carrying a felt cover. The felt is made from the wool of the flocks of sheep that accompany the pastoralists. The timber to make the external structure is not to be found on the treeless steppes, and must be obtained by trade in the valleys below.
The frame consists of one or more expanding lattice wall-sections, a door-frame, bent roof poles and a crown. The Mongolian Ger has one or more columns to support the crown and straight roof poles. The (self-supporting) wood frame is covered with pieces of felt. Depending on availability, felt is additionally covered with canvas and/or sun-covers. The frame is held together with one or more ropes or ribbons. The structure is kept under compression by the weight of the covers, sometimes supplemented by a heavy weight hung from the center of the roof. They vary with different sizes, and relative weight. They provide a surprisingly large amount of insulation and protection from the outside cold of winters, and they are easily changed to keep the yurts cool for summertime.
