Thermally insulated steel/steel connection

Steel structures are a well established component of modern

architecture. As an elegant, transparent construction they

offer excellent opportunities when combined with other

materials such as glass, concrete or wood and provide the

building with a certain lightness, predominantly in industrial

and residential construction. Steel structures frequently

creating spacious and impressive large span areas.

Where steel construction is concerned, particular attention

needs to be paid in the detailing of components that

penetrate through the exterior shell of a building. With

conventional construction methods, thermal bridges are

created at the transition from the building to the projecting

component. These lead to increased energy consumption,

risk of condensation formation and the associated growth of

mould. Thermal bridges impair, not only the quality and value

of the building, but also the room climate.

According to current building regulations, thermal

bridges should be reduced. The Egcobox® FST

offers the ideal solution for the thermal isolation of

steel structures without restricting the structural

effectiveness of the support system.

Thermal separation of steel structures

Features of the Egcobox® FST

■ reduced thermal bridging

■ high structural functionality and corrosion resistance

■ CE marking according to EN 1090

■ type tested

■

■ insulation: polystyrene (standard) or rock wool on request (A1)

The Egcobox®

geometry and the structural requirements.

With the Egcobox® FST, distinction is made between

components for tensile force stresses as well as normal or

shear force stresses. A component consists of threaded

rods, with a diameter of 16 mm or 22 mm, arranged in pairs.

® FST is

unnecessary.

The type designation does not provide information about

the dimensions of the Egcobox® FST. The Egcobox® FST is

adapted in the factory to the existing installation geometry.

The data required for the manufacture can be easily created

with the help of the design forms (see pages 20/21).

Example 1:Egcobox® type FST16–1/1 or FST22–1/1

consisting of:

1x FZST16 component or 1x FZST22 component

and

1x FVST16 component or 1x FVST22 component

Only threaded rods of the same diameter (Ø16 or Ø22) may be used in one Egcobox® FST.

2x FVST16 component or 2x FVST22 component

Fire protection

including the Egcobox®

for the entire steel support structure must also be taken into account for the

Egcobox® FST.

In the standard version, the Egcobox® FST is manufactured with polystyrene

as the insulating material. At the customer's request, however, the Egcobox®

FST can be manufactured completely from components of building material

class A1 according to EN 13501 (rock wool insulation). The use of alternative

insulation material rock wool depends on the geometry of the connection

and should be checked according to project requirements by MAX FRANK.

Fire protection measures are not implemented in the factory and must

therefore be carried out on site. The responsible specialist planner carries

Fire protection variants

■ The entire structure, including the Egcobox® FST, is to be clad on site

■ Fire protection through coating (B)

The entire steel structure including the protruding threaded rods and

level of the Egcobox® FST must additionally be protected all round by

Thermal insulationApart from the legal regulations, the owners' demands on thermal insulation

are also continually increasing. The focus here is not just on environmental

protection and the saving of heating costs, but also on a healthy room

climate and thus on the prevention of condensation and the formation of

mould.

The following factors must be considered when assessing the rotation:

■ Only the torsion spring stiffness is calculated, the vertical spring can

be neglected.

■

■ Deformations can additionally occur in the adjoining structures.

■ Torsional forces cannot be absorbed by the individual Egcobox®

FST components and must therefore be compensated by the

complete structure.

Deformation / rotationThrough the use of an Egcobox® FST, a cantilever beam, for example, is

rigidity must be applied for the Egcobox® FST than for the steel beam. On

account of the moment action with cantilever beams, the associated torsion

from the Egcobox® FST is to be taken into account. The rotation of the

Egcobox® FST can be stated with:

n [pc.] Number of threaded rods per connection

Fixing informationThe following tightening torques are recommended to secure the steel

connection:

Movement jointsComponents in the steel support structures are to be designed so that the

deformations that occur do not impair the stability.

Structural damage often occurs as a result of inadequate detailed planning.

Amongst other things, different temperature expansions can lead to

stresses in the steel structure. The maximum distance between Egcobox®

FST elements that are not interrupted by a movement joint must therefore

be limited to 6.0 m.

The threaded rods must subsequently be caulked. Further notes on

installation on page 22.


Formation of the end plates

Geometrical boundary conditions need to be observed in

the planning of the Egcobox® FST. These include minimum

distances between the components for tensile or normal and

shear force stresses as well as the minimum thicknesses

threaded rods with the same diameters (ø16 or ø22), as well

as a symmetrical layout of the components, is permitted.

In accordance with type testing, exclusively the compressively stressed threaded rod is to be taken for the determination of the shear force per Egcobox® FST. A reduction in the tensile force ZRd is therefore unnecessary.Please contact our technical support regarding any necessary additional shear force transfer in the tensile area.For Egcobox® 18
