HT 24plus Dimensions and tolerances Product standard Calculated values Standard lengths Weight Package units 14 Mayr-Melnhof Kaufmann 240 mm 80 mm Dimensions HT 24plus Tolerances Beam height 240 mm + / - 2,0 mm Chord thickness 40 mm - 1,5 % Chord width 80 mm - 1,5 % Web thickness 26,6 mm + / - 0,5 mm Industrially manufactured formwork timber beams are to be used in supporting structures and formworks for concrete buildings. The load is applied in the direction of the formwork beam height. The EN 13377 standard specifi es the classifi cation, the requirements, and verifi cation procedures for formwork beams in the heights h = 16, h = 20 and h = 24 cm. According to EN13377 Carrying capacity characteristics Lateral force V k = 28,2 kN permissible Q = 13 kN Bending moment M k = 14,1 kNm permissible M = 6,5 kNm Reaction of support R b,k = 56,4 kN MOE x moment of inertia EI = 775 kNm² Elasticity module of chord (C24) E Chord = 11.000 N/mm² Elasticity module of web (SWP) E Web = 6.700 N/mm² TECHNICAL DATA 2,45 / 2,50 / 2,65 / 2,90 / 3,30 / 3,60 / 3,90 / 4,20 / 4,50 / 4,90 / 5,90 / max. 10,00 m 5,1 kg/m 40 mm Standard package: 80 pieces Version 1 / 2011
