Used Peri Slab Formwork
When using the Peri Skydeck drop head system, disassembling can be completed in only one day (depending on the thickness and strength of the slab). A hammer blow can cause the drop head formwork to drop 60 mm (panels and main beams). The panels can be separated easily from the concrete and immediately returned into duty, as well as, minimizing on-site material requirements. The Peri Skydeck main beam reduces the number of multi props needed – only one prop is required per slab area of 3.45 m² for thicknesses up to 40 cm. This method will save time and simplifies the transportation of formwork materials across the work site.
The Peri Skydeck edges of the panels are undercut which to ensure that cleaning is kept to a minimum and thus shorter shuttering times. Peri Skydeck panels as well as main beams are equipped with self-draining edges.
Organized assembly and a high level of safety for standard bays as well as the slab edge are achieved using Peri Skydeck platforms. The SLT 375 main beam provides a cantilever of approx. 1.30 m. The GS-approved Peri Skydeck SDB platform together with a foldable handrail frame is safely positioned by means of the SSH shuttering aid. The Peri Skydeck platform has a safe working load of 150 kg/m².
Peri Skydeck guarantees a straight support line at the end of the formwork. These system parts can infill areas to be quickly formed with system components.
For slab thicknesses up to 95 cm
With the Peri Skydeck drop head system, striking can be carried out after only one day (depending on the slab thickness and strength of the concrete). The drop head is released with a hammer blow will cause the formwork to drop 60 mm (panels and main beams). The contractor can then easily take apart the Peri Skydeck parts from the concrete and to be immediately reused. Additionally, job material requirements are minimized. The Peri Skydeck main beam reduces the number of props needed – only one prop is required per slab area of 3.45 m² for thicknesses up to 40 cm. This saves time and simplifies the transportation of formwork materials across the site.

Peri Skydeck has been used all around the world in multiple applications;
Tallinn, the capital of Estonia, is the 2011 European Capital of Culture. As centerpiece of the cultural activities, a historical domed structure dating from the time of the last Russian Czar is currently being refurbished and converted into an attractive maritime museum. The PERI UP scaffolding system has been optimally adapted here to suit the geometry of the almost 100 year old reinforced concrete complex and has been used for a wide range of applications on both the interior and exterior.
The structure, with its three impressive domes, was built in 1916/1917 as a reinforced concrete construction – for the time, this was a very unusual feat of engineering. The self-supporting shell-shaped construction without any disturbing intermediate supports was originally designed to serve as a hangar for seaplanes. However, the Russian Revolution prevented later utilization of the facility. Now, the historical domed structure is being extensively refurbished and should be open to the general public in the summer as a maritime museum.
Berlin, Germany – For the construction of a new bunker as well as refurbishment of an existing bunker at the Ruhleben waste incineration facility in Berlin, the PERI UP modular scaffolding system proved to be an extremely versatile solution: as a load-bearing scaffold for the structural work of the new waste and slag bunker along with a weather protection roof and assembly platform required for the extensive renovation work of the existing bunker roof while the plant was in operation.
In the challenging new structure, intermediate slabs were to be constructed at various and several different levels and in several areas. For supporting the slab formwork, a PERI UP birdcage scaffold with heights of up to 22.50 m was used. Due to the metric grid design, the scaffold could easily be adapted to suit the complex geometry as well as the transfer of a wide range of high loads.
In areas of extreme loads, the legs were bundled together. In this way, the scaffold was able to safety transfer knife-edge loads of up to 280 kN/m – resulting from a down stand beam and an approximately 20 m high wall – into the ground from a height of more than 22 m. The static optimization of the scaffold for the different areas along with the respective loads not only resulted in a reduction of material requirements on the construction site but also in a reduction of the time used for assembly and dismantling.
A high degree of flexibility to the supporting structure also required the fact that ground contact areas on different levels had to be realized. These boundary conditions could also be implemented with PERI UP with maximum accuracy.
Mississauga, Canada – Two spectacular high-rise buildings are currently twisting and turning upwards into the Canadian sky. During the construction of the extremely complicated building geometry, the PERI RCS climbing protection panel is ensuring rapid building progress and maximum working safety.
Two curvaceous skyscraper towers form this urban-development highlight as part of the new Absolute World City Center in Mississauga. The inner-city ensemble consists of five apartment and office blocks with heights of up to 170 m. Very striking and exceptional, however, are the rotations of the two buildings: the southern tower with a varying rotational movement and the northern tower which twists uniformly upwards.
For both structures, the complete enclosure of the upper floors through the RCS climbing protection panel ensured the safety of the construction site team which has resulted in higher productivity. Due to the different rotations by different degrees at different levels, PERI engineers developed two unusual climbing methods – with the help of the modular construction system, adapted specifically to suit the respective project requirements and building geometry
