Timber structures - Prefabricated wall, floor and roof elements - Structural (load-bearing) elements with adhesively bonded sheeting made of wood-based panels on one or both faces (EN 14732-2) cen:proj:70596

Scope

This European Standard sets out requirements regarding the performance of characteristics of structural (load-bearing) prefabricated wall, floor and roof elements consisting of framing members of structural timber, structural finger jointed timber, glued solid timber, glued laminated timber, laminated veneer lumber (LVL), structural prefabricated wooden beams/columns and sheeting made of wood-based panels bonded adhesively on one or both faces, for use in service class 1 or 2 in accordance with EN 1995-1-1. At least one of the sheetings contributes to the load-bearing capacity of the element.
The cavities of the prefabricated elements may be filled entirely or partially with insulating materials. The exterior faces of the elements may also be covered with insulation material. This European Standard covers prefabricated wall, floor and roof elements with a sheeting thickness of maximal 60 mm.
This European Standard also lays down procedures for Assessment and Verification of Performance of Characteristics (AVPC) and specifies marking and labelling of structural (loadbearing) prefabricated wall, floor and roof elements with adhesively bonded sheeting on one or both faces.
This European Standard covers prefabricated wall, floor and roof elements with adhesively manufactured bonds using an adhesive of Type I according to EN 301 with performance characteristics deemed to satisfy the characteristics of the prefabricated element in service class 1 and 2.
This European Standard covers structural (load-bearing) – wall elements with a maximum length/height or height/length of 16,5 m x 4,0 m and of unrestricted thickness – floor and roof elements with a maximum length of 12,5 m, a maximum width of 4,0 m and a maximum thickness (relevant for composite action) of 0,50 m. This European Standard specifies characteristics of load bearing and non-load bearing
components for the prefabricated elements. This European Standard applies to prefabricated elements that may have openings, e. g. for windows, doors, etc. It does not apply to characteristics of incorporated doors or windows. This European Standard does not cover curved elements.
This European Standard does not cover elements with framing members with holes except for round holes at mid depth with a diameter d ≤ 1/10 of the framing member depth.
The elements may be used in seismic areas with adequate design and materials. They are not intended for use in fatigue situations.
This European Standard applies to prefabricated elements with untreated components and/or components treated against biological attack.
This European Standard does not cover components and prefabricated elements treated with fire retardants.
