Abstract
Abstract A portable and demountable building structure where the roof and walls are formed of a plurality of substantially equal sized panels joined together at the edges by special H-shaped joiner strips. The panels are formed by a pair of rigid skins of a formed plastic material and a core of low-density material such as foamed plastic. Each skin has L-shaped connecting flanges in back-to-back relationship with the flanges of the other skins. The H-shaped connectors engage the panel connecting flanges in a resilient manner to tightly retain the flanges together. Special corner pieces join the H connectors together at the corners and join the roof to the side walls at gabled portions thereof. A special roof central ridge connector rigidly joins roof panels together forming a rigid peak. Window and door structures are formed within regular sized panels.
