Concrete shell construction method

摘要

A shell structure construction method utilizing a plurality of anchored and laterally connected pre-cast reinforced concrete shells, each of these subject shells has a specific shape in which the shell walls are defined by an inverted catenary shape or alternatively by other efficient geometric shapes. An improved joint support mechanic includes a combination of fastener elements and a plurality of post tensioned cable systems disposed between and connecting contiguous shell elements. This construction method is suitable for manufacturing and implementing severe storm shelters used during tornadoes and other severe weather events.

1. A storm shelter comprising:
a plurality of shells having a first surface with a recess to house a flange, a second surface and a third surface, said shells connected to each other by a connecting mechanism having a member on the shells to strengthen said storm shelter; a structure connected to the second surface of said shells to anchor said shells to the earth to enable said storm shelter to withstand wind load; and a supporter connected to the third surface of the shells to support the shells to provide integral rigidity, stiffness and strength to said storm shelter; wherein said connecting mechanism connects said shells to each other by connecting said member on said shells to the flange housed in said recess at an angle to strengthen said shells by allowing load bearing.
