Thermotec E connector

Thermotec E connectors can withstand higher shear forces compared to standard A connectors. The connector only transfers shear forces and bending moments in one direction.

Its main advantages are:

high load capacity of a single element transferring shear forces,
simple construction.

Load capacities given in tables have been prepared for typical cases and the reinforcement ratio at the level of 0.5% and 1%. Load capacities for higher ratios of the reinforcement, elements close to edges and connector systems can be determined according to the procedure in the last chapter of the catalogue Thermotec E balcony connectors allow the transfer of transverse forces and bending moments acting in one direction without the need to meet the minimum ratio of the moment and the shear force.

Characteristics of the Thermotec E connector: :

Slab thickness: h=160 – 250 mm,
Insulation thickness of 80 mm – resole foam with the coefficient λ=0.021,
Minimum concrete strength class: C20/25,
Fire resistance: REI60 in a variant with a top firestop plate,
REI120 in a variant with two plates.

Notes:
- strictly observe the assembly direction marked on the connector.
- the presented diagram is a recommendation that draws attention to the most important aspects of connector assembly. Specific cases and solutions used on the construction site may need to be completed.

The contractor is responsible for the correct installation method. In order to clarify any questions or doubts, please contact the EXTREA technical department.
