ABSTRACT:
A plurality of at least two plate or panel-type members are formed with edge portions which hook together to define a key-forming passage therebetween, with tongue-and-groove type interlocks directed laterally from the elements defining both sides of the passage. The passage is filled with initially flowable, solidified key-forming material injected therein under pressure sufficient to cause the injected material to flow along and fill all, or one or more selected portions of the passage. The elements of the panels defining such passage are so formed that the pressurized, injected material tends to expand the passage, and thereby urge adjacent edges of the two panels toward abutting relation with each other, whereby further expansion of the passage is prevented. Upon solidifying, the injected material comprises a key, which interlocks the panels and seals the joint therebetween.
