In order to facilitate the restoration of balconies of the kind comprising concrete slabs (2) projecting from the building body (1), coffers (3) are used to enclose such concrete slabs (2). For fastening of the coffers (3) to the concrete slab (2) one upper tie rod (4) and one lower tie rod (5) are secured in the concrete slab (2) in the area thereof closest to the building body (1). The tie rods (4, 5) project from the building body (1) in the area of the joint between two coffers (3) positioned one on either side of the concrete slab (2), and externally thereof they are interconnected by means of a first vertical stay (9). A second vertical stay (10) extends from the lower tie rod (5) downwardly, alongside the building body (1). A pressure stay (11) extends between the second vertical stay (10) and the lower tie rod (5). The first vertical stay (9) is provided with a securement plate (13) bridging the joint between two coffers (3) and arranged to retain the latter in position in abutment against the building body (1). |
