PRODUCT DESCRIPTION
The MK System is a product designed for heavy-duty structures of high load- earing capacity mainly used in civil
engineering.
Its main feature is its versatility to configure all types of structures such as gantry structures, formwork carriers and
tunnel structures, shoring structures, horizontal and vertical formwork, other structures for formwork support,
clim ing rackets, sla perimeter protection structures and other applications.
The core item for all these solutions is the Waler MK. Its ela orated design and the com ination with various
accessories, oth unique of the MK system as well as shared with other ULMA products, ena le to adapt it to all
those a ove mentioned applications.
With the MK Structure system, two or more load- earing structures are formed in one direction, the so-called main
axis. These structures are raced to each other giving the required sta ility to the whole as well as a sor ing wind
loads acting on the structure in perpendicular direction to the main axis.
Depending on their field of application, mainly two structure types are distinguished:
−MK Truss Structure
MK Truss StructureMK Truss Structure
MK Truss Structure
−MK Form Carrier Structure

MK TRUSSMK TRUSS
MK TRUSS
A truss structure, i- or multi-supported, supports the formwork and a sor s the loads acting on the formwork.
The formwork systems commonly used with the MK Truss Structure are Enkoform VMK or Enkoform H-120.
The typical truss form of the structure is achieved with equilateral triangles consisting of Walers MK and Nodes MK
assem led in the same plane. These structures are raced to each other with joints and tu es. Depending on the
required load- earing capacity of the truss, the main axis can e reinforced with push-pull props and tu es.
The Waler MK range allows assem ling trusses of different load- earing capacities. The most optimum load-
earing capacity-weight ratio is the one given y a distance of 3 m etween nodes axes and 2.6 m etween waler
axes.

If the span of the upper oom (or element that works at compression) is sought to e reduced or the ending
capacity to e increased, a vertical tu e is used to make the structure ear higher loads.
The spans possi le to cover with the MK Truss Structure change depending on the waler length used. Moreover,
the permissi le working load changes depending on the layout of the truss structure.
The com ination of the MK Truss Structure system with the MK Shoring system offers an even wider range of
solutions as shown in the following figures.

The following types of form carriers can e erected with the MK system:
−Deck flange form carrier
−Parapet form carrier
−Vertical formwork carrier
−Cut-and-cover tunnel form carrier
1.2.1. DECK FLANGE FORM CARRIER
DECK FLANGE FORM CARRIERDECK FLANGE FORM CARRIER
DECK FLANGE FORM CARRIER
In the case of metallic ridges which are made up of pre-cast components or of a pre-cast centre part, it is
common to uild the wings in a su sequent stage. This can e done with deck flange form carriers. These are
heavy-duty form carriers as the jacks are a le to withstand a maximum load of approximately 360 kN. Due to the
load orne y the structure, the forward-moving of the form carrier is achieved y means of pull or push auxiliary
devices.
A deck flange form carrier with these properties usually consists of the following parts:
oMain structure: structure earing the concrete load.
oForward-moving structure: secondary structure which effects the movement and ears the forces
during such.
oBracing: components that withstand wind effects and transverse movements.
oFormwork: part in touch with the concrete shaping it, allowing its adjustment and opening if this is
required for the movement of the structure.
oRolling and levelling system: components that ena le the rolling of the truss and its levelling at a
specific place, as well as its stripping.
oSafety items and access: walkway platforms, handrails etc., depending on the requirements of each
project.

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.
A further distinction may e the requirement to cast oth wings at the same time or one after the other.
In the first case, the rolling system rests on a guide rail to move the formwork to su sequent casting positions. It
can e applied in those cases where there is a solid ase (pre-fa ricated or pre-cast) to support the guide rail and
the levelling jacks on.

In the second case, it is the other way around. The ogie forms part of the secondary structure and the rolling
system is fixed to the ridge. This is rather common where there is no pre-cast structure (e.g. metallic ridges).

PARAPET FORM CARRIER
This form carrier is a lighter version of the previous one. It is used for applications with lower load- earing and
forward-moving capacities. Unlike the one mentioned eforehand, the parapet form carrier can e moved manually
and requires a solid ase where the guide rail rests on. The jacks of this form carrier type are a le to withstand a
maximum load of approximately 150 kN.
The most common applications for parapet form carriers are the construction of protection parapets for ridges or
solutions that do not require high load- earing capacity, mainly projects with formwork ta les.

oBracing: components that withstand wind effects and transverse movements.
oFormwork: part in touch with the concrete shaping it, allowing its adjustment and opening if this is
required for the movement of the structure.
oRolling and levelling system: components that ena le the rolling of the truss and its levelling at a

VERTICAL FORMWORK CARRIERVERTICAL 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 y the self-weight of the structure. Its load- earing and forward-moving capacities
are still lower than the ones of the a ove mentioned form carriers. The jacks of this form carrier type are a le to
withstand a maximum load of approximately 60 kN.
As the parapet form carrier, the vertical formwork carrier can e moved manually and requires a solid ase where
the guide rail rests on. It is mainly used in the construction of single-sided or dou le-sided concrete walls. In the
case of single-sided walls, there are considera le horizontal loads which must e taken into account when using
the vertical formwork carrier.

The solution with the MK system for cut-and-cover tunnels can e regarded another type of form carrier adapted to
the particular requirements of tunnel construction where the structure must adapt to the vault shape of the tunnel.
This form carrier type also applies to applications where walls and sla s are cast at once as it is the case of
rectangular section tunnels.
Vaulted tunnels are usually not cast at once ut in stages: first the ga les then the top part of the vault. Cut-and-
cover tunnel form carriers are complemented with swivel parts to facilitate the stripping and forward-moving of the
structure.
An all-round solution for cut-and-cover tunnels com ines 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:
oMain structure: structure earing the concrete load, oth the vertical as well as the horizontal loads.
oForward-moving structure: secondary structure which effects the movement and ears the forces
during such.
oBracing: components that withstand wind effects and transverse movements.
oFormwork: part in touch with the concrete shaping it, allowing its adjustment and opening if this is
required for the movement of the structure.
oRolling and levelling system: components that ena le the rolling of the truss and its levelling at a

oSafety items and access: walkway platforms, handrails etc., depending on the requirements of each

Cut-and-cover tunnel from carriers vary depending on aspects such as the load- earing 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 ogie.

ack face-to-face. There are three rows of holes. The
holes of the outer rows have a diameter of ∅ 17 mm
and the spacing etween holes of the same row and
towards the other outer row is 62.5 mm.
In the centre row, holes and slots alternate, the holes
have a diameter of ∅20 mm, the slots have a length
of 45.5 mm. The spacing etween the holes in the
centre row is 125 mm.
The centre rows always start and end with ∅20 mm
holes.
2.2.2. NODE 180 MK AND NODE 180 D40 MK
The Node 180 MK ena les to connect up to 4 walers
placed at 60º. That is, two walers are connected
lengthwise with a remaining gap of 375 mm
etween their respective ends, and the other two are
placed at 60º to the previous ones. The connections
are fastened with 6 olts M16 inserted into the D17
holes.
The Node 180 D40 MK differs from the previous one
with respect to the connection of another (male)
item to the node centre in a hinged way pointing
downwards. The connection is fastened with pins
D40.
In oth cases, the D20 holes are mainly used for the
connection of secondary components, i.e., racing
items.

2.2.8. NODE 60 SUPPORT MK
The Node 60 Support MK is a kind of foot to support
the structure on something, mainly on profiles. It
works as support of a i-supported truss.
It ena les to connect up to 2 walers at 60º as the
Node 60 MK does. The connections are fastened with
6 olts M16 inserted into the D17 holes.
The support plate provides D25 (25 mm diameter)
and D22 holes to connect other items and
accessories.
2.2.9. ORT OGONAL JOINT MK
The Orthogonal Joint MK connects up to 3 walers
perpendicular to each other. The connection with the
waler is fastened with 4 olts M16 inserted into the
D17 holes.
It can also connect 2 walers lengthwise. In this case,
each waler is fastened with 6 olts M16 inserted into
the D17 holes .
This connector has medium load- earing capacity
and is mainly used in light form carriers.
2.2.10. AXIAL NODE M D20 MK
This node ena les to connect one waler to another in
a hinged way, always in the main plane. The waler
and the node are fastened with 2 olts M16 inserted
into the D17 holes. Unlike the Axial Node M D40,
this one does not have high load- earing capacity.
The hinged connection etween the waler and the
node is fastened with pins E20x70.
