Industrially prefabricated VST elements are designed individually according to individual customer requirements. During the entire process of industrial prefabrication, the highest precision is guaranteed. On the construction site, work is minimized to the assembly and concreting of elements. After this process, the concrete core is permanently bonded to the cement chipboards.
Innovative elements of VST (in translation: composite formwork technology) are made of cement-chipboards with a thickness of 24 mm, which consist of 70% cement and 30% wood particles.
VST construction components meet the highest quality requirements, are significantly lighter than conventional concrete elements and are characterized by simple and quick assembly. A high degree of prefabrication reduces construction time without limiting the customer's freedom of design. The patented VST composite formwork system is suitable for all load-bearing and non-load-bearing structures. Depending on the requirements, building elements such as walls (vertical or inclined), slabs (horizontal or inclined), columns, beams, formwork, stairs and special elements can be produced.
The VST walls consist of two cement chipboards with a thickness of approximately 24 mm, which are connected to each other by special spacer profiles. If necessary, reinforcement, empty electrical pipes, as well as heating and sanitary pipes can be built into the walls of the VST. Walls are produced according to an individual production plan. All openings and penetrations (eg for doors, windows, empty electrical conduits, etc.) are cut at the factory. The wall thickness is variable depending on the design requirements. On the construction site, the cavity between two cement chipboards is filled with concrete. This permanently bonds the concrete core to the cement chipboards. VST walls are generally used as load-bearing walls.
VST ceilings are a quick finish to the substrate. The cement-bonded particleboard slabs are delivered to the site and laid, onto which special steel hat beams have been bolted at the manufacturing factory. On site, only the formwork components are placed on top of the normal base slabs and concreted in place once the reinforcement has been installed. The height of the profiles is uniformly 50 mm and the overall thickness of the slab is 75 mm (irrespective of the thickness of the concrete layer). For VST ceilings, openings are already taken into account in the manufacturing process to ensure a simple and trouble-free installation process.
The VST beam effortlessly takes the load from ceilings, arches or walls and transfers it in a structurally sound manner. It consists of three cement-bonded particle-board panels that are connected to each other by spacers or metal brackets, as well as factory-fitted reinforcement according to the static requirements. The dimensions of the VST beam are freely selectable and, even with a maximum length of 13 m, it is strong enough to support any building.
The VST staircase can be effortlessly assembled right at the start of the construction work. This not only saves unpleasant emergency solutions such as the use of ladders, but also increases safety on site. The risers and the lower parts of the VST staircase are made of cement-bonded particleboard, the risers of wooden formwork. As with all VST components, the reinforcement is factory-installed and there is no need for additional work steps. Once the staircase has been relocated, simply concrete it and remove the timber formwork once the concrete has cured. The staircase can be plastered or tiled as desired. VST staircases are suitable for both indoor and outdoor use and are designed entirely according to the customer's wishes. The advantage is that they can be combined with different acoustic solutions.
With a maximum circumference of 2.8 m, the VST columns are up to any challenge. In addition, VST columns can be combined with manufactured punching heads. VST columns are quick and easy to assemble and, once concreted, are fully integrated into the building, not only visually.
Whether with single or double bends, the VST roof dormer is made to measure according to the customer's wishes and requirements and there is no need for lengthy and time-consuming formwork on site. The factory cut-out of the window also ensures that the glazing fits precisely and no labour intensive adjustments are required.
The 24 mm thick cement-bonded particleboards, which serve as the base for all VST components, can be used as formwork (composite or decking) or as a stand-alone component, e.g. for raised beds or non-load-bearing components. Indoors, they are ready for painting after installation and require no additional sealing. The components are supplied as standard with a length of 100 cm and a width of 62.5 cm and weigh 35 kg/m²². Other sizes are available on request.
The VST ventilation shaft provides supply and/or extract air where this is not possible with windows, or serves as a connection to the outside air for intelligent ventilation of the living space. VST ventilation and light shafts can also be thermally separated, so there is no need for insulation, saving costs and time.
In addition to a wide range of tested VST construction components, customers can also choose special customized solutions. Balconies, interior walls, attics, installation walls and many more can be realised using prefabricated VST components, among others. This makes it possible to create a complete shell construction in the VST system - the components of the VST composite formwork can be combined with each other, allowing for a consistent solution. All special components can be individually designed and are manufactured in the semi-automatic part of the factory. This means that they can be manufactured and customised to the customer's exact requirements.
The first automated production line of VST BUILDING TECHNOLOGIES AG was opened in Nitra, Slovakia, in the autumn of 2013. It is the most modern and largest factory - with an area of almost 17,000 square metres - for the production of building components such as walls and slabs in Europe.
At the VST production factory in Nitra, we manufacture the patented VST composite formwork system for "off-site construction" according to individual customer designs. The automation of the production line represents a technological breakthrough in the industrialisation of component production, as it makes the entire production process much more efficient and cost-effective. On the one hand, the use of raw materials in production is reduced and, on the other hand, the need for labour is reduced. Automation has also significantly increased the overall production capacity of the Nitra factory.
