The recoverable form sheathing is esp. suitable for effecting connections for two ro more prefabricated wall slabs in cellular silo construction, where the demands of rapid construction mean that the wall slabs must be fixed in position as quickly as possible, so that the concrete can be cast in the corners. The wall slabs (1) with their end faces (6) defining the space (2) which is to be filled with cast site concrete, are fixed relative to each other with a hinged frame (7) of metal shaped-section pieces (3). Against this are braced wedges (4) to hold form sheathing units (5) adapted to the angle enclosed by adjacent wall slabs, and thus align the latter. The form unit may form an extension of the walls slabs into the concreting space, and it may be trapezoid cross-section. |
