A prefabricated concrete panel, a method of making a panel joint, and a panel joint made this way

摘要

The prefabricated concrete panel (1) has tongues (2) and grooves (3) on the contact surfaces with a cavity (5) open from above. Inside the panel (1) there is an anchor (6) with a jaw (8) which has a recess (7) that follows the shape of the cavity (5). The panel joint is formed by inserting an anchor bolt (11) into the cavity (5) and casting it with a rapidly curable fixative (12). The solution reduces the consumption of concrete, improves the flatness of the walls and strengthens the head part of the panels (1), so that the wall panels (1) can be directly tied to the ceiling structure without the need for reinforced concrete bracing.
