Abstract
According to the present invention a building element comprises a generally planar panel defining at least one substantially straight side end and a first connecting lug extending co-planarly to the panel from the substantially straight side end. The first connecting lug extends along only a portion of said straight side end, and a slot is provided in the form of an elongate aperture extending partly into the first connecting lug or partly into the panel adjacent to the first connecting lug. The slot extends adjacent to the straight side end and parallel thereto, and the slot is open at one end thereof. The arrangement is such that two building elements with slots being open at opposite ends can be attached to each other by positioning the panels at right angles to each other and sliding the slots over each other in a direction along the straight side ends in order that the slots engage the elements. The invention also relates to structures formed by using the above elements.
