Concrete Placement

Подпись:Once the forms and ties have been inspected and oiled, the forms are ready for concrete. Minimum concrete strength must be at­tained, usually through cylinder strength tests, before the forms can be raised.

Stripping

Once the concrete in the second lift has attained sufficient strength, the taper ties and other embedded items are removed. The outside forms are then rolled back on the mounted trolleys.

The interior forms, which are attached to the top grid beam, allow for small movement and are released at this time.

The form support bracket at the bottom is also released at this time, leaving the system supported on the rams and the ram support brackets.
