High load-bearing capacity structures up to 360 kN
are obtained with triangular structures. These
structures are mainly used for solutions such as
gantry shoring systems, trusses, deck flange and cut-
and-cover tunnel form carriers.
These structures are characterised by using walers for
all diagonal and horizontal connections in direction
of the main axis, and by using such nodes that allow
of connecting one, two, three or more walers at 60º.
Those can be alternated at determined points of the
structure with nodes allowing of waler connections
at 90º and 45º.
All high load-bearing capacity joints are fastened
with 6 bolts M16 quality 8.8 and their corresponding
nuts providing a maximum tensile or compression
load of 360 kN to the node.
The triangular structures are formed with the same
waler size, the load-bearing capacity increasing
proportionally to the waler length. However, there is
another limitation to the structure at buckling in the
direction of the weak or secondary axis.
The waler providing the best structure weight–
working load ratio is the Waler MK-120 / 2.625
enabling a distance between nodes of 3 m.
Usually the structure is assembled at once, although
it might be useful to divide the assembly in modules
in order to ease future operations such as the placing
of the structure into its final position.
Medium load-bearing capacity structures up to 150
kN are characterised by using more frequently
tubular elements for the diagonal and horizontal
connections, reserving the walers for the most
demanding parts of the structure. These structures
are mainly used for solutions such as vertical
formwork carriers or parapet form carriers.
Medium load-bearing capacity joints are fastened
with pins D20 providing a maximum tensile or
compression load of 75 kN to the diagonals and 360
kN to the walers. Moreover, there is the load
limitation of the tube used for the diagonals and
horizontal braces.
