  • 3. improved acoustic performance
 
 

SYSTEM TO LIGHTEN WAFFLE SLABS

Skydome cross section

 

SKYDOME  is a modular formwork  system in ABS plastic used to build two-way ribbed slabs completely on-site. This product allow to create a bi-directional slab inspired on the caisson, i.e. to build a monolithic casting of orthogonal ribs with an upper slab of adequate thickness.

 

The system was designed to decrease the weight of traditional full-concrete slabs . The dome-shaped forms create a matrix of voids surrounded by orthogonal ribbing, thus producing a two-way configuration very suitable for large-spanning slabs .

 

The SKYDOME  system includes a range of ABS domes of various depths (H 250, 300, 350 e 400 mm), set on special interlocking supports, which make assembly fast and easy.

 

Accessories

    • Skydome Cube

      Cube

      The cube allows the connection of the beams to complete the network. H has the same size of the beam in order to be adequate to the system. 

      C120 – C160 – C200

    • Skydome Flat Cube

      Flat cube

      The flat version permits the place of the elements right on the flat deck creating a double formwork.

      CF120 – CF160 – CF200

    • Skydome Flat Beam

      Flat beam

      The flat version permits to place the elements right on the flat deck creating a double formwork.

      TF120 – TF160 – TF200

    • Skydome Beam

      Beam

      Allows the creation of place network for the dome. The beam width is decided during the project stage.

HOW MANY TIMES CAN THE MATERIAL BE REUSED?

ABS plastic is extremely resistant, therefore all GEOPLAST formwork can be reused more than 100 times.

WHEN CAN THE SYSTEM BE DISMANTLED?

SKYDOME system can be dismantled even after 4-5 days. However, it is necessary to post-prop the slab until full curing of the concrete. In every case, the right dismantling time must be approved by the plan design according to the type of concrete used on-site. 



A slab formwork to build biaxial waffle slabs in residential and commercial buildings, The system was designed to decrease the weight of traditional full-concrete slabs. The dome-shaped forms create a matrix of voids surrounded by orthogonal ribbed slabs structure, creating a two-way configuration very suitable for large-spanning slabs.

 

The self-weight of concrete slab formed with SKYDOME is up to 30% lower than a full concrete slab. This is an advantage as it reduces the oscillation of a building during an earthquake. The product is also an advantage in terms of noise reduction, improving the acoustics in a building.

 

SKYDOME formwork for reinforced waffle and ribbed slabs is great also important in particular environments, such as schools or public buildings.

 

Its main advantages are:

 

SEISMIC RESISTANCE: the slab reduces the mass of the structure improving the seismic performance

 

LIGHTNESS: the elements are very light and ca ben easily installed and handled.

 

REUSABLE: ABS plastics does not stick to concrete, thus dismantling is extremely easy making the formwork very quickly to use for the next cycle.

 

ARCHITECTURE: the waffle slab is pleasing to the eye and can be left exposed, creating aesthetically enjoyable environments

 

ACOUSTICS: the shape of the domes reduces sound waves, improving the acoustics of the structure.
