1 NEW HAFEN Adjustable Cantilever A REVOUTION IN TUNNE PIPE SUPPORT

2 HAFEN Adjustable Cantilever The advantages at a glance The HAFEN Adjustable Cantilever combines the established high load bearing of the medium duty system with much faster installation. Specifically designed for tunnels or other areas with a curved or inclined substrate. It is not necessary to know the cantilever angle at the time of design. NEW! ONE PART FOR A OCATIONS, DRAMATICAY REDUCED COMPEXITY suitable for pipe clamps, shoes and cable trays can be used for laid or suspended pipes takes up site tolerance. Cope with changes due to site conditions NO CUSTOM CANTIEVERS REQUIRED, NO ANGES TO MEASURE simplified design no risk of custom cantilevers not fitting rapid delivery of stock item no custom fabrication lead time 2

3 Introduction The KON 41/V cantilever is freely adjustable from an angle of -56 to +56, and can be fixed to curved castin channel or surface-mounted framing channel or directly to the tunnel wall including curved or inclined surfaces KON 41/V is made without welding, and is composed of a HAFEN Framing channel 41/41 cantilever arm and an adjustable HVT rear bracket. The HVT rear bracket may also be used separately as a fixed support connection element in the HAFEN 41 Framing Channel System to restrain the rotation of a beam, unlike hinge connection elements. 56 Serration inside the HVT bracket The cantilever is available in three standard lengths. Custom lengths are also available. The KON 41/V cantilever is easily set to the correct angle by loosening the serration plates. The bracket is set to the required angle, then the assembly is simply re-tightened. Tried and tested HAFEN Cast-in or Framing channel with HAFEN Bolts. The ideal team for fastening in any environment. For cast-in channels please refer to our catalogue "Technical Product Information HAFEN Cast-in channel". 3

6 HAFEN Adjustable Cantilever KON 41/V Calculation Example Calculation of the adjustable cantilever KON 41/V is based on the static calculation models as shown in the figures. The example is based on a cantilever with two mounted pipes of different diameter and a cable tray. The example is calculated with design values. oads: F Z,1 0,95 kn F X,1 0,10 kn F Z,2 1,90 kn F X,2 0,20 kn 1,10 kn/m q Z , ,5 Design loads: F Z,1,d 1,4 F Z,1 1,33 kn F X,1,d 1,4 F X,1 0,14 kn M Y,1,d 2,065 F X,1,d 0,14 kncm F Z,2,d 1,4 F Z,2 2,66 kn F X,2,d 1,4 F X,2 0,28 kn M Y,2,d 2,065 F X,2,d 0,58 kncm q Z,d 1,4 q Z 1,54 kn/m ,5 170,5 129, Calculation model 1 for design of: Calculation model 1 F Z,1,d F Z,2,d HZM 41/41 or HM 41/41 profile: Bolt 1 (S1) Bolt 2 (S2) M y,1,d M y,2,d q Z,d shear forces at infinite distance to bolt 2 from both sides R 1,Ed 77 F x,1,d F x,2,d R 2,Ed 61,5 129, V Z,Ed V Z,Rd V R Z,Ed V Z,Rd bending moment above bolt 2, considering shear force on both sides M Y,Ed M Y,Rd (with V Z,Ed) ρ if required M Y,Ed M Y,Rd (with V R Z,Ed) ρ if required N Ed R N Ed N Ed normal force on both sides of bolt 2 N Ed N Rd (ρ if required) N Ed N Rd (ρ if required) V z,ed R V z,ed V z,ed S1 R1,Ed S2 My,Ed R 2,Ed
