PFEIFER S-20 TIMBER FORMWORK BEAMS
Pfeifer S-20 timber formwork beams are panel web beams conforming to EN 13377. 1) The beams are manufactured according to the general building supervision license of the German Institute of Structural Engineering. Licence number: Z Â 9.1 Â 299 2) Length: 245 (8'), 250, 265 (8,7'), 275, 290 (9,5'), 300, 330 (10,8'), 360 (11,8'), 390 (12,8'), 450 (14,7'), 490 (16'), 590 (19,3') cm (Inch) Special lengths up to 12 m are available 3) Dimensions: 40,5 31 Dimensions in mm 4) Dimension tolerances: Height H=200 +/- 2 mm length tolerance: specified length +/- 10 mm 5) Weight: 4,6 kg/lm 6) Identification of the beam: -Licence number (Z Â 9.1 Â 299) -Beam length -Date of manufacture -U mark Characteristic limit value: Vk = 23,9 kN Mk = 10,9 kNm H=200 80
7) Instructions for dimensions: 7.1) the admissible transverse force 7.2) the admissible bending moment
Qperm = 11,0 kN Mperml = 5,0 kNm EJ = 450 kNm2 J = 4180 cm4 7.3) For dimensioning ceiling thicknesses we refer to our table giving the maximum permissible pile beams and distances between supports.
The cutting conditions specified in the following must not be exceeded at any place on the timber formwork support: 8) Provisions for the Execution: The span of the timber formwork support may not exceed 4.00 m. The formwork shell is to be placed directly on the upper boom and nailed on. The timber formwork supports are to be secured against tilting according to static requirements. 9) Provisions for Usage, Maintenance, Service: Before every usage of the timber formwork supports, these are to be checked for perfect condition by the installation firm. Supports weakened due to damage or rotting are to be excluded from use.
