Schöck Isokorb® type module CEQ 2
The Schöck Isokorb® type CEQ transmits loads from earthquakes from the balcony into the floor slab in
interaction with the Schöck Isokorb® type CM, the Schöck Isokorb® type CMD or the Schöck Isokorb® type
CV. The Schöck Isokorb® type CEQ1 absorbs shear force parallel to the insulating layer. The Schöck Isokorb®
type CEQ2 absorbs shear force parallel to the insulating layer, pressure and tensile force normal to the
insulating layer and positive moments.

Orientation of Schöck Isokorb® module CEQ
Attention: the Schöck Isokorb® type CEQ does not have a symmetrical design. The tension bar must be at the bottom.
— The tension bar must be at the bottom.
— The horizontal shear force bars are always 113 mm [4 7/16"] from the bottom edge of the Schöck Isokorb® type CEQ and the
underside of the slab.
— Pay attention to installation orientation and show a cross section view on the design drawings.

The Schöck Isokorb® CEQ modules may be arranged with maximum spacing of 1/2 of the expansion joint distance of the Schöck
Isokorb® type. These are shown in the respective product chapter. The illustration shows the example of combination with the
Schöck Isokorb® type CM.
The expansion joint spacing shown in the illustration corresponds to a temperature difference of ∆T = 70 °C [126 °F].

Notes
— The design values relate to the individual element.
— ΦMn and ΦNn do not occur simultaneously. The Engineer of Record (EOR) must consider the interaction between bending
moment and normal (axial) force.

Checklist
~
Have the factored member forces at the Schöck Isokorb® connection been determined at design level?
~
Has the critical concrete strength been taken into consideration in the choice of design table?
~
Have the requirements with regard to fire protection been determined, and has the relevant suffix (-R90 or R120) been
added to the Isokorb® type designation in the design drawings?
~
Have the maximum permissible expansion joint distances "e/2" from the fixed point been taken into consideration?
~
Has the moment resistance of the CM/CEQ assembly been reduced (by 1/1.1) to account for the installation of the CEQ
module?
