Abstract
Abstract An improved connector for a supporting filter bank framework is disclosed which comprises a body member defining at least two extensions radiating from a common central location. Each of the extensions has a U-shaped cross sectional configuration so as to define a bottom wall and two opposite side walls. A threaded coupling member may be disposed at the central location for securing the connector to a supporting tie rod, and a protuberance is disposed within each U-shaped extension at a predetermined distance from the central location. Adjacent connectors are adapted to be joined by an interconnecting channel of predetermined length, with the ends of the channel being positioned within aligned extensions of adjacent connectors, and with the ends of the channels abutting the respective protuberances. A supporting latticework is thereby constructed which defines a plurality of rectangular open areas, and the length and width dimensions of each open area is automatically established. Each extension of each connector further includes a transverse groove extending along the entire inside surface thereof, and an aperture extending through one of the walls and communicating with the groove. A caulking material may be forced through the aperture after the interconnecting channel is secured in the extension, and so that the caulking material is able to flow along the groove and form a seal between the extension and channel. Most of the individual steps involved in the assembly of the latticework may be accomplished as one continuous operation, which avoids the need for repeatedly laying down and picking up the several required tools.
