Overview

EN 14992:2007+A1:2012 is the CEN European standard for precast concrete products - wall elements. It sets requirements for prefabricated wall elements made from normal-weight or lightweight concrete with a dense structure, and permits use of fibre‑reinforced concrete where covered by relevant European standards. The standard covers a wide range of precast wall types (solid, composite, sandwich, lightened, cladding) that may be plain, reinforced or prestressed, loadbearing or non-loadbearing, and may also serve as columns or beams. Amendment A1 (2012) aligns the standard with related product rules and EU provisions, including CE marking where applicable.

Key topics and technical requirements

• Scope & types: Defines solid, composite, sandwich, lightened and cladding wall elements and their functions (external wall functions and facing functions).
• External wall functions: Thermal insulation, sound insulation and hygrometric control (moisture/condensation considerations).
• Materials: Normal‑weight and lightweight concrete; fibre‑reinforced concrete allowed per EN 14889/EN 15422 and other relevant standards (fibres typically not accounted for in structural calculation unless stated).
• Design & structural rules: References Eurocode design (EN 1992‑1‑1) and common precast rules (EN 13369); includes additional design guidance in informative Annex A.
• Production & tolerances: Factory production control, dimensional and surface flatness tolerances (classed tolerances), and recommended reinforcement distribution for typical wall thicknesses.
• Fire, acoustic and thermal performance: Requirements for fire resistance and reaction to fire; acoustic and thermal properties per EN 13369 and referenced methods.
• Durability & moisture: Water vapour permeability (EN ISO 12572) and water impermeability/water absorption tests referenced.
• Conformity & marking: Type testing, factory production control and CE marking provisions (Annex ZA) linked to the Construction Products Directive.

Additional design rules A.1 Composite wall elements A.1.1 Loadbearing design A composite wall should be designed like a solid wall. Without special calculation the minimum strength of the precast element and the in-situ concrete should be taken into consideration. The designed reinforcement may be located inside the element and/or in the in-situ concrete. The same applies to walls acting as deep beams. For the design of the reinforcement the joints of the composite wall should be taken into consideration. This is of particular importance for the determination of the effective depth d (see Figure A.1 and A.2). The design of laps has been specified by EN 1992-1-1:2004, 8.7. If a lap between bars requires transverse reinforcement according to EN 1992-1-1:2004, 8.7.4.1 (3) links, u-bars and lattice girders can be used separately or in combination (Figure A.1). If lattice girders are used as transverse reinforcement, the maximum diameter of the lapped bars should be 16 mm. It is recommended to limit the maximum cross section that may be lapped to 1200 mm2/m. A.1.2 Shear at the interface The connection between cast in-situ concrete and compound unit in the final state should fulfil subclause 6.2.5 of EN 1992-1-1:2004. A.1.3 Loadbearing compression joints in case of loadbearing walls Subclause 10.9.2 of EN 1992-1-1:2004 may be used. The required reinforcement in subclause 10.9.2 (2) of EN 1992-1-1:2004 may be met by lattice girders too. In case of composite walls the whole cross section may be taken as loadbearing provided the joint is completely filled with in-situ concrete and has a width of at least 30 mm. If this is not provided, only the cross section of the in-situ concrete should be taken as loadbearing (see Figure A.2). The effective depth is the distance between the centre of concrete force and the reinforcement. SIST EN 14992:2007+A1:2012

Key 1 rib 2 longitudinal bar 3 transverse reinforcement 4 concrete layer Figure A.3 — Examples of reinforcement of a rib A.2.2 Reinforcement for sandwich walls The following specifications should apply: a) base panel; it should be reinforced as a solid wall; b) facing panel; the layer should contain vertical and horizontal reinforcement. The reinforcement should be designed to support the actions due to the !connector system", the weight of this layer, thermal effects and long term effects in service. The maximum distance between two bars of the reinforcement should not exceed 200 mm; c) reinforcement !connector system"; the !connector systems" should be designed to connect the base panel with the facing panel and to transfer to the base panel the loads acting upon the facing panel. A.2.3 Reinforcement for lightened walls The following recommendations may apply: a) characteristics of the ribs !deleted text":  ribs are defined according to A.2.1;  maximum space between two concrete ribs: 40 times the thickness of the facing panel in the case of transversal ribs; 50 times the thickness of the facing panel in the case of longitudinal ribs;  minimum thickness of a rib or diameter of a concrete connection: 50 mm;  concrete ribs and connections may be substituted by stainless steel elements suitably designed or other connecting systems.

18 Annex B (informative)
Concreting of composite walls on site Unless special provisions are taken the precast part of the wall should not have a temperature below 5 °C during concreting. After concreting the fresh concrete should not have a temperature below 10 °C for at least 3 days or should have a minimum compressive strength of 5 MPa before the temperature of the fresh concrete falls below 0 °C. The maximum formwork pressure may be taken from Figure B.1.
