Abstract
A facade construction made of plate-like construction elements having ground edge faces at which the elements are joined with one another without mortar. The plate-like construction elements have interior cavities, the cavities of superimposed construction elements forming through-going air passages connected toward the outside at least in the top and bottom portions of the facade. The ground edge faces form horizontal bearing-surfaces and vertical abutting-surfaces relative to adjoining construction elements. Between these horizontal bearing-surfaces and/or vertical abutting-surfaces of adjoining construction elements locking elements or elements for connection with the means securing the facade to a wall are arranged.
