Abstract
This joint system is provided primarily for connecting elongated structural members which are made of materials which deter the use of conventional fastening techniques, and specifically for joining pultruded composite structural members composed of, for example, glass fibers and resins. The joint system in the first embodiment includes an elongated pultruded member which defines one or two re-entrant slots along its entire length, with the interior structure defining the walls of the slot or slots being configured to cooperate with the inserted seating end of another composite length such that when the length is inserted into one of the slots, the slot is first expanded slightly and then the walls of the slot snap back to lock with cooperating structure of the other structural member. In a second embodiment a sleeve-like equivalent of the slot configuration is set forth and lastly, a high-voltage power line tower constructed with the joint coupling as its central feature is described.
