Waler on V Bracing Truss MK joint

There is still another way to join two walers. That is

with the V Bracing Truss MK and without any

additional part. The V bracing can only be fixed to

the centre of a main truss waler, and only if tubes are

used in the application.

4.3.

BRACING BETWEEN STRUCTURES

Bracing between structures is understood as all tubes

and joints used to connect two or more equal

structures parallel to each other and thus also

reinforcing them in the secondary plane.

This tubes and joints framework structure must

mainly be able to absorb secondary actions such as

lateral wind, forces during the process of forward-

moving of the structures and forces due to

inclinations or slopes of the application.

In some cases, these loads might happen to be

important, therefore the requirement to use bracing

which transmits the actions to the structure axis.

There is another possibility to externally brace the

structures. However, this bracing does not offer the

same qualities of the previous one and may only be

used when actions in the secondary plane are

certainly not important.

4.3.1.

Bracing on waler axis

For this type of bracing, diagonals and horizontal

braces are used, joined to the walers with U

secondary axis joints fastened and with pins D20.

Hence these connections are all hinged which

requires them to be also braced diagonally at some

points to achieve an appropriate bracing for all the

structures.

The bracing system transmits the forces to the waler

axis, and the horizontal braces join and determine

the distance between two adjacent structures. More

structures can be braced parallel to the other, always

in the secondary plane.

4.3.2.

Bracing off waler axis

Tubes and couplers are directly fixed to the Handrail

Head MK joined to the walers and fastened with 2

bolts M16.

This type of bracing does not offer the same qualities

of the previous one and is not advisable to be used

with high load-bearing capacity structures.

Its main advantage is its simplicity (few elements) and

ease of assembly hence it is very useful for the

bracing of light structures. It may also be used to join

two independent, that is, self-standing sets or form

carriers which are not supposed to be moved.
