Abstract

A method for laying and mechanically joining rectangular building panels in parallel rows includes the steps of (a) placing a new one of the panels adjacent to a long edge of a previously laid first one of the panels in a first row and to a short edge of a previously laid second one of the panels in an adjacent second row, such that the new one of the panels is in the second row, while holding the new one of the panels at an angle relative to a principal plane of the first panel, such that the new one of the panels is spaced from its final longitudinal position relative to said second panel and such that the long edge of the new panel is provided with a locking groove which is placed upon and in contact with a locking strip at the adjacent long edge of the first panel; (b) subsequently angling down the new one of the panels so as to accommodate a locking element of the strip of the first panel in the locking groove of the new panel, whereby the new panel and the first panel are mechanically connected with each other in a second direction with respect to the thus connected long edges, wherein the long edges, in the angled down position of the new panel, are in engagement with each other and thereby mechanically locked together in a first direction also; and (c) displacing the new one of the panels in its longitudinal direction relative to the first panel towards a final longitudinal position until a locking element of one of the short edges of the new one of the panels and the second panel snaps up into a locking groove of the other one of the short edges, whereby the new one of the panels and the second panel are mechanically connected with each other in both in the first direction and in the second direction with respect to the thus connected short edges.
