Prestressed hollow core slabs are reasonably categorized as the most advanced products in the construction sector. They can satisfy newly established market demands.
Their characteristics are: construction efficiency, highly automated process of production which is environment-friendly, high level of concrete strength, speedy construction, fire resistance, quality of the construction works performance, sustainable construction, etc.
The production of hollow core slabs takes place on runways by the method of extrusion of special concrete with the help of slipform pavers which form slab section with continual interior hollow cores. The production width of slabs is 120cm, the length is variable whereby thickness depends on load and the span of slabs.
The thickness of slabs can be 20cm, 25cm, 30cm, 35cm and 40cm. Depending on load, required span and water resistance, the values are read from the catalog and the types of slabs selected. Tables of bearing capacities in the catalog are used for the selection of the slab type in the stage of preliminary design and they do not replace structural analysis.
Main advantages of prestressed hollow core slabs
Elements are produced in smooth formwork in the factory under controlled conditions. For the production of prefabricated elements the company uses self-compacted concrete produced in the completely automated concrete factory within the production complex. The procesing of reinforcement take place in the factory circle making the process of monitoring the whole production easier and more intensive.
Our prefabricated elements can take different profile and variable lengths which ensures their flexibility and wider scope of the application of the prefabricated concrete construction in building construction. The additional capacity to prestress elements enables great construction rasters and the realization of most demanding projects. The prefabricated concrete construction consists of foundation cups, columns, primary roof beams, purlins, interfloor beams, prestressed hollow core slabs, parapet beams.
