Slab formwork, otherwise commonly known as decking, is a horizontal temporary system that is in place to support and transfer self weights, imposed loads and environment loads during stages of construction to the shoring.
Uni-Span boasts five slab formwork systems which include the Uni-Deck Panel system, the Timber Beam and Board system, the Lajflex Grid system and the Alufort system.
Timber or steel secondary and primary bearer formwork on props is the most versatile slab formwork and can be utilized in very complex arrangements where the more modular systems would be difficult to use.
Modular slab formwork is a system that comprises of prefabricated timber, steel or aluminum beams and formwork modules. Modules are often no larger than 1 – 2m in size. The beams and formwork are typically set by hand and pinned, clipped, or screwed together. The advantages of a modular system are as follows:
- No crane is required to place the formwork,
- Less labour intensive which increases the speed of construction
- Formwork modules can be removed after concrete sets, leaving only shoring in place prior to achieving design strength
These solutions can be used for applications that include bridge decks, flat slabs and coffered slabs.
Shoring is a vertical temporary structure that is in place to support and transfer all loadings from the formwork system to the ground.
Uni-Span’s shoring solutions comprise of Uni-Stage, the High-Load Frame System, Props and Steel Beams. Uni-Stage is a steel framework system that is cost effective and versatile in its application. The High-Load Frame System is a modular steel system that can support up to 70 kN and is less labour intensive. Uni-Span’s shoring systems, which include heavy-duty props, spanning beams (Uni-Max) and girders are geared to provide support in heavy construction projects within the civil and construction sectors.
