Abstract: The present invention relates to an attachment system for forming a substantially planar wall structure, intermediate and end connectors to be used in the system, and a method of assembling the system to form the desired wall structure. The intermediate connector joins adjacent ones of the wall panels and comprises two panel retention members in an overlapping relationship. Each panel retention member has a base portion, a web portion, and two substantially parallel, non-coextensive, integral flanges defining a recess for receiving an edge portion of a wall panel.

Abstract: An apparatus for joining panel members into walls or divider is provided which does not require the use of a wet sealant to close the gap between adjacent panels and which allows thermal expansion and/or contraction of the panel members to be absorbed by the joints. The apparatus includes a channel for receiving turned down edges of adjacent panel members. The channel has interlocking portions for engaging mating portions on the panel edges and locking them into position. An insert is positioned within the channel between the edges to hold the interlocking and mating portions in engagement. The insert has protruding surfaces for wedging the portions together and a neck shaped portion for joining the insert to a cap or gasket for sealing the gap between the panel members. The cap or gasket includes a hollow interior portion for receiving the shaped portion of the insert and a pair of shoulders for retaining the shaped portion within the hollow portion.

The apparatus includes a channel for receiving turned down edges of adjacent panel members. The channel has interlocking portions for engaging mating portions on the panel edges and locking them into position. A resilient spring member is used to hold the interlocking and mating portions in engagement. A profiled elastomeric sealing member is provided to seal the gap between the panel members. The sealing member is held in position by the resilient spring member.
