Abstract: A shelter structure constructed of a plurality of modules or lobes each of which includes a pair of triangular panels having curved edges connected together with the apices thereof spread apart and supported by pedestals in elevated relation to a supporting surface. Adjacent edges of the lobes or modules are secured together by a connector and the pedestals are secured to the lower apices of the modules by splice plate assemblies. The lobes or modules are assembled into a building or shelter structure by a unique manipulative procedure to facilitate the construction of a shelter on site thus enabling the modules to be conveyed to the site in a partially assembled condition and then expeditiously set-up and assembled into a shelter structure.
