Resumen
The invention allows to lock factory walls of different height and composed of materials of different dimensions and nature, by introducing a meeting board, consisting of a vertical component and two or more that slide along it. The first one is arranged along the junction between the two walls, while the second ones are inserted by the upper part of the vertical component and slide vertically through it but without the possibility of horizontal displacement. Both components are placed between the two factory walls, preventing vertical and horizontal movement once they are executed. The vertical component can be continuous or consist of discontinuous elements, aligned along the unión between factories. The number of elements that slide along the vertical component will depend on the stiffness that you want to give to the joint and the applicable technical regulations, depending on the materials to be used.
