ABSTRACT:
A device for reinforcing a rear surface of a wall includes a receiving bag (4) attached to one end of an axial extending filling stub (1). Webs (3) are attached to the receiving bag (4) and the filling stub (1) so that the webs and receiving bag can be folded from a radially outwardly extending position toward the axis of the filling stub whereby the receiving bag and the webs can be folded into a position so that the combination of the webs (3), the receiving bag (4) and the one end of the stub (1) can be inserted through an opening (6a) in the wall (6). In the inserted position, the webs (3) return to the radially outwardly extending position along with the receiving bag (4) and the bag is filled with a hardenable mass (7) through the filling stub (1). A fixing element (5) is inserted between radially and circumferentially extending ribs (2) on the filling stub (1) located on the opposite side of the wall from the receiving bag (4). The fixing element (5) limits the depth that the filling stub (1) is inserted through the wall. After the mass (7) has hardened, a part of the wall (6) is reinforced at its rear surface by the mass, and fastening elements, such as screws, nails and the like, can be inserted through the wall into the hardened mass.
