Jointing means between building elements (2), which are provided with an edge (1) which is arranged to be jointed together with a corresponding edge of another building element forming a sealed joint. The edges are provided with at least one groove (3) extending from the edge in inwards direction into the element. In the space formed by the each other opposing edge surfaces of the grooves of the two elements a long rail element (34) is inserted. According to the invention the rail element comprises a first rail (6) with a front surface and a second rail (6) with a front surface, which rails are by means of connecting means (7) connected with each other in such a position that the front surfaces are facing in outwards direction and are pressed against the sides of the grooves (3). The rails are fixed abutting against the sides of the grooves by means of a mass introduced between the rails, preferably a foamed plastic composition, which stiffens forming a string of cellular plastic between the rails. The rail device by this arrangement forms a resistant and the building elements engaging locking element for the same. |
