SINGAPORE Complicated Marina Development [cont]

Flying Peri table - SingaporeTables moved quickly and safely
With SKYTABLE large-area slab tables, which are up to 20 m long and five metres wide, close to 100 m² of slab formwork are quickly and safely moved with only one crane lift.

By means of a lifting mechanism, specially developed for this system, and the chain guidance shoe for transferring the force at the slab edge, the table can be pulled horizontally from the building and then lifted immediately to the next shuttering position.

During the moving procedure, the operating personnel are always positioned in a safe and secure place on the slab edge and do not have not to stand on the table.

In spite of the huge table sizes, the SKYTABLE system is extremely flexible. Using PERI MULTIPROP aluminum slab props, a large lowering height is achieved, with slab offsets of up to 200 mm and, at the same time, 50-centimetre parapet wall heights.

In addition, the MULTIPROP props can be connected by means of MRK frames in order to form towers. Thus, SKYTABLE tables can be flexibly used for the intermediate storey heights of almost nine metres as well.

Peri Marina Bay Singapore From the outset, PERI engineers took into consideration the continuously changing geometry with their solution and used an unchanged SKYTABLE framework construction for the entire height of the building.

This has meant that any table modifications required have been kept to an absolute minimum, and time-consuming, costly conversion work which could lead to misapplications have been avoided as far as possible.

Climbing without a crane
The PERI ACS self-climbing system is the optimal formwork scaffolding for the altogether twelve elevator shafts constructed in advance. With the help of ACS (Automatic Climbing System), the different-sized shafts with dimensions ranging between 2.30 and 10.10 m can be shuttered, struck and Peri Lift Shaft construction - Singaporeclimbed in four-day cycles without the need of a crane. Altogether, five safe and secure working levels climb at the same time to the next section: two platforms for forming, reinforcement work and concreting the shaft walls as well as three finishing platforms for pre-tensioning the subsequent storey slabs. In combination with CB climbing scaffold and the VARIO GT 24 girder wall formwork, PERI ACS has thus optimised the operational sequences on the construction site.
