    MK STRUCTURE STRUCTURE STRUCTURE STRUCTURE 1.1. MK TRUSS MK TRUSS MK TRUSS MK TRUSS A truss structure, bi- or multi-supported, supports the formwork and absorbs the loads acting on the formwork. The formwork systems commonly used with the MK Truss Structure are Enkoform VMK or Enkoform H-120.

  • Page 8 MK STRUCTURE STRUCTURE STRUCTURE STRUCTURE There are two types of deck flange form carriers: Those where the rolling system is part of the form carrier (i.e. integrated in the secondary structure) or − Those where the rolling system is not part of the form carrier.

PARAPET FORM CARRIER PARAPET FORM CARRIER PARAPET FORM CARRIER PARAPET FORM CARRIER This form carrier is a lighter version of the previous one. It is used for applications with lower load-bearing and forward-moving capacities. Unlike the one mentioned beforehand, the parapet form carrier can be moved manually and requires a solid base where the guide rail rests on.

VERTICAL FORMWORK CARRIER VERTICAL FORMWORK CARRIER VERTICAL FORMWORK CARRIER VERTICAL FORMWORK CARRIER The main feature that distinguishes the vertical formwork carrier from others is that the vertical loads acting on the structure are exclusively caused by the self-weight of the structure. Its load-bearing and forward-moving capacities are still lower than the ones of the above mentioned form carriers.
  • Page 11 An all-round solution for cut-and-cover tunnels combines the MK Structure system for the top part of the vault with the MK Shoring system. A cut-and-cover tunnel form carrier usually consists of the following parts: Main structure: structure bearing the concrete load, both the vertical as well as the horizontal loads.
  • Page 12 MK STRUCTURE STRUCTURE STRUCTURE STRUCTURE Cut-and-cover tunnel from carriers vary depending on aspects such as the load-bearing capacity and the area where it is supported on and moved forward. Two types of cut-and-cover tunnel form carriers are distinguished regarding a restricted or free support area. In all cases, the rolling system forms part of the form carrier, i.e. it is integrated in the bogie.
