BRESPA-Decke Typ A22B (DW Systembau GmbH)

This is a Cradle to gate with modules C1-C4 and module D LCA.

Ceiling type A22B consists of prestressed prefabricated concrete elements (prefabricated prestressed concrete ceilings) for use as ceiling components. The ceiling height is 22 cm, the standard width of the ceiling elements is 1,20 m, narrower ceiling widths are possible. The transport weight of the A22B is 3,07 kN/m². The concrete is made from aggregates, water, hydraulic binders (cement), admixtures and additives. Apart from the prestressing steel, no other reinforcement is required. Cold-drawn prestressing steel strands and wires are used for the production of prefabricated prestressed concrete slabs, which are stretched over the 120 m long strips. These are high-strength steels. Regulation (EU) No. 305/2011(CPR) applies to the placing on the market of the product in the EU/EFTA (with the exception of Switzerland). The products require a declaration of performance taking into account the harmonized standard EN 1168:2005+A3:2011 Precast concrete products - hollow core slabs/ and the CE marking. The respective national regulations apply for use. Cement EN 197 is added to the natural aggregates (sand, grit, gravel) as a binding agent. Fly ash or granulated blast furnace slag can also be added. Depending on the type, bulk density and grain size, the aggregates are stored in silos in the factory or stored separately in the open air. The binder and additives are stored in silos. The dosed aggregates are first removed from the silos and premixed dry with the binder. The mixture is then mixed with water to form a malleable concrete. After treatment, the process water is used for cleaning purposes in the plant. The prefabricated prestressed concrete slabs are produced with extruders and slipform pavers on heatable steel tracks as hollow cross-sections with the required thickness and prestressing reinforcement. After the concrete has cured to a strength that allows the floor elements to be further processed, the floor elements are cut to the required length and temporarily stored on the factory premises. Cold-drawn prestressing steel strands and wires are used to produce the prefabricated prestressed concrete slabs, which are stretched over the 120 m long strips. These are high-strength steels.

Prestressed precast concrete elements are used as ceiling elements in interior and exterior areas. The market areas that this product can be used for are the following: -Residential and residential buildings -Office and commercial buildings -Industrial and hall construction - Shopping centers -Schools and kindergartens -Hotels and event venues -Parking structures
