• Large-format panels for example made of plasterboard, are known from the field of interior construction and are attached to suitable supports. For example, these panels are attached to metal profiles in the area of drywall to create new partitions. Alternatively, the panels can be attached to a lath connected to a wall or to sloping ceilings, such as the beams of a roof truss, to form cladding.
• the plates can be over man-high and have a width of more than 1 m.
• Such panels are known as "one-man panels” and have dimensions of approximately 1.50 x 1.00 m, for example. There are also larger ones as standard Plates, for example with dimensions of 1.25 x 2.50 m, which can usually only be handled by two people.
• a smooth and unobtrusive transition must be created on the abutting edges of the panels.
• the abutting edges of the plates each have a flattened area in the joint area of two plates.
• the plates are therefore bevelled at the edge, so that there is a comparatively flat flattening on the abutting edge of two adjacent plates.
• This can be filled with filler.
• a textile strip is then inserted into the moist filler.
• the panels are connected to each other in a tensile manner, for example in order to prevent later crack formation in a wallpaper attached above them.
• a panel element which can be connected to an adjacent panel element by means of a tongue and groove connection.
• the groove is limited by two so-called groove cheeks.
• On the groove cheek which is located on the side facing away from the room in question, there are recesses for receiving fastening means.
