The pendulum has a first arm (4a) running parallel to the casting mould inner surface, and a second arm (4b) running at right-angles in a construction component (2) formed after casting. The first arm is bent away from the construction component, remaining orientated at right-angles to it. A wall clamp (7) is fixed to the free end of the arm (4a') and is encased in one or more seams (23, 24) between bricks forming the wall (11). - The pendulum (4) has a cross-section permitting that when the casting mould is removed the first arm can be bent outwards slightly in relation to the second arm, and can then be bent further to the required position, at the same time being maintained straight. |
