An arrangement for securing a wall structure on a fixed building wall comprises a securing device 26 and a locking device 27. The securing device 26 comprises a shaft 1 with an end portion 2 for engagement with a bore hole in the building wall, and the shaft 1 has an axial hole 4 and its engagement portion 2 has axial slits 7 forming radially expandable tongues 8 and peripheral flanges 3 for pressing against the wall of the bore hole. The locking device 27 comprises an expansion body 11 which has a greater cross section than that part 4a of the hole located within the engagement portion and is designed to be introduced into the hole of the shaft in order to radially expand the tongues and press the flanges against the bore hole wall for obtaining a powerful locking engagement. According to the invention, the locking device 27 has a rod 9 which extends through the hole 4 of the shaft 1, and a rotary element 12 which is supported by the rod 9 on its end directed away from the engagement portion 2 of the shaft 1. The expansion body is supported by the rod 9 and is located outside the engagement portion 2 in its unexpanded state, the said expansion body being designed to be moved into the engagement hole 2 by turning of the rotary element 12. <IMAGE> |
