EN 14991:2007 - Precast concrete products - Foundation elements

1 Scope
This European Standard deals with the requirements and the basic performance criteria and specifies where applicable minimum values for precast foundation elements (comprising columns with integrated foundation elements, pocket foundation elements, sockets) made of reinforced normal weight concrete for structure of buildings according to EN 1992-1-1.
This European Standard covers terminology, performance criteria, tolerances, relevant physical properties and special aspects of transport and erection.
This European Standard does not cover the bearing capacity determined by testing.

3 Terms and definitions
For the purpose of this document, the terms and definitions given in Clause 3 of EN 13369:2004 and the following apply.
pocket foundation element
precast reinforced concrete unit capable of transferring vertical actions, bending moments and horizontal shears from structural components of the structure (e.g. columns, foundation beams, walls) to the soil (see Figures B.2 to B.4)
column with integrated foundation element
precast foundation element forming part of a column and permanently fixed to it
either vertical part of a pocket foundation element (see Figures B.3 and B.4) or separate precast unit corresponding to that part (see Figure B.1)
horizontal part of the pocket foundation element
NOTE It can either be a part of a pocket unit or be cast on site.
pocket with keyed surfaces
pocket expressly wrought with indentations or keys at the vertical internal surfaces of the socket
pocket with smooth surfaces
pocket with the internal surfaces of its socket smooth as cast
product family
group of foundation elements of the same type and shape, with the same critical dimensions and manufactured with the same type of concrete (type of concrete: see EN 13369:2004, 3.1.8)
