Subconstruction

Cladding

Load bearing walls may consist of:R/C (concrete), steel, brickwork:

•full brick,

f t d b i k•perforated brick,

•light concrete,g

•aerated concrete,

t•etc.

Insulation

Nearly all thicknesses of insulation can be usedused.

Ventilation spaceVentilation space

In Germany: ≥ 20 mm.y

In other countries: National regulations to be complied with!complied with!

Cladding material

A various number of different cladding materials formats and fixing methods can materials, formats and fixing methods can be used.

• Systems for visible fixings

• Systems for hidden fixings

Subconstruction

The subconstruction has to comply with the type of cladding, its fixing method, the load yp g, g ,bearing wall as well as the forces acting on it.

• Therefore BWM invented and designed useful substructure systems y

• (ATK 100 Minor, ATK 103 ...)

In order to enable stress-free changes in length of the sections due to temperature variations, the sections are usually fixed

Use of a rivet setting gauge for stress free dilatation on sliding points

or use of special sliding point screws forL-brackets

In a statical calculation all parts of the subconstrction are proved against collapse.p g p

Required material /information:q /

• Type and format of the cladding material• Distance to the wall / insulation thickness• Type and quality of the load bearing wall• Wind loads / building data in order to determine the

wind loadsB ildi l ( i / ti )• Building plans (views / sections)

Mounting plans based on the statical calculation specify the position of the calculation specify the position of the sections and fixings at the building.
