(57) On the contact surfaces, the panel (1) is provided with tongues (2) and grooves (3) with a cavity (5) open from above. Inside the panel (1), there is an anchor (6) provided with jaws (8), which is provided with a recess (7) following the shape of the cavity (5). The anchor pin (11) is inserted into the cavity (5) and is poured over with a quick-setting fixative compound (12). The solution saves time during installation that does not require the use of fixing spacers (15), reduces the consumption of concrete, improves flatness of the walls made and reinforces the head portion of the panels (1) so that it is possible to bind the wall panels (1) directly to the ceiling structure without making reinforced concrete ring beams.
