Abstract From the Canadian patent

Securement and cooperation between panels of an office panelling system is improved by mechanically connecting panels in a manner to maintain a particular orientation and to allow transfer of loads therebetween. The mechanical fasteners are advantageously combined with compressible strips between panels which not only deform during fastening of the fasteners but, engage the panel and distribute the clamping force to a larger area thereby adding structural rigidity.
