Abstract
A construction system is disclosed utilizing prefabricated panels which can be assembled in a contiguous, aligned relationship to form a construction section. In one form of the system, the individual panels may include a structural core with a flexible membrane covering, and include an edge portion adapted to engage the edge portion of the next adjacent panel to provide a substantially continuous seal between panels. The edge portions are sealable by fasteners which may be in the form of interlocking male and female members proportioned so that when joined the male members of one fastener will wipe along the inside walls of the fastener to which it is being connected to clean dirt from these walls and push the dirt into one or more dirt cavities formed when the fasteners are joined. Multiple areas of intense contact are also provided between the mating members of the fasteners to provide an effective watertight seal. The fasteners may be pre-shaped during manufacture to increase the pressure along the areas of intense contact after joining. Also, a distinctive indicator, such as a color stripe along one or more of the ribs of each of the fasteners, may be provided which is visible…
