Multiform Circular Walls

Recoverable formwork system for straight and curved walls.

Vistaform Walls is a system designed to be handled with a crane. Vistaform Walls consists of a phenolic plywood board and a mixed support structure composed of wooden beams (HT-20) and steel profiles.

Thus the system can be arranged considering its standard modules but also special modules can be studied to be customized to the architect’s project. Regarding the panel systems with metal frames Vistaform Walls ensures that the joints between panels are almost imperceptible as both are made of phenolic plywood board, providing a good fair-faced concrete finish.

SYSTEM CHARACTERISTIC
  • Standard modules: length: 8′-2 7/16” (2,5 m), heights, combinations with elements of 4′-3 3/16”, 5′-10 7/8”, 8′-7/16”,11′-9 3/4”and  16′-15/16”(1,30, 1,80, 2,45, 3,60 and 4,90 m).
  • Minimum inside radii: 13′-1 1/2” (4 meters) (with 1/16” (18 mm) thick phenolic plywood), from 9′-10 1/8” to 13′-1 1/2”  (3 to 4 m) (with 1/16” (12 mm) thick phenolic plywood) and from 8′-2 7/16” to 9′-10 1/8” (2,5 to 3 m) (with tropical or Finnish phenolic plywood).
  • Allowable pressure: 11023 Ibs 5.000 kg./ m2 (50KN/m2), (with 11/16” (18 mm) thick phenolic plywood) and 9920 Ibs 4.500 kg./ m2 (45KN/m2), (with 1/2” (12 mm) thick phenolic plywood).
ADVANTAGES OF THE SYSTEM
  • Good fair-faced concrete finish.
  • Joining and aligning with manual clamp.
  • With only four tie bars in the 8′-2 7/16” x 8′-2 7/16” (2,5 x 2,5 m) modules the impact can result in more than 1,5 m2 per tie bar.
  • It can be used to implement at the same time both, straight and curved walls just modifying the metal beams.
  • In the case of curved walls the radius can be changed without disassembling the system.
  • With only four tie bars in the 8′-2 7/16” x 8′-2 7/16”  (2,5 x 2,5 m) modules the impact can result in more than 1,5 m2 per tie bar, very important in wastewater treatment plants and watertight deposits.
