Abstract: A structural connection device is disclosed and is formed of a plurality of hub components having extending ear pairs for connecting with elongated struts or the like for constructing spatial structures. The hub components are positioned in stacked abutting relationship and connected into a unitary device via a single elongated rod connector disposed through and sealed within a large single axially aligned perforation extending centrally through each of the hub components. Adjacent hub components are rotated relative to each other prior to assembly to provide an angular relationship between the respective ear pairs of adjacent hub components.The elongated rod connector 16 (FIGS. 1-2), and 16a (FIG. 3) is fixed to the hub components by shrink fitting, force fitting or adhesively bonding. Other connection embodiments utilize a key-keyway arrangement (FIGS. 4-5a), a cross-pin arrangement (FIGS. 6-7a) and a star or gear shaped connector element (FIGS. 8-9).

Abstract: A connection for structural members is provided including a plurality of hub components each having projecting ears for receiving the end of a structural member, with the components being rotated to define angles between the respective ears of adjacent hub components, and with the hub components being precompressed together by bolt means.

Abstract: A hub for use in a space frame assembly which can be joined to a like hub by a strut member by bolt means connecting the strut to the hub in a preset spacing and in which the bolt means includes spherical bearing surfaces for positioning and a column member surrounding each bolt means to provide a compression load transfer path.
