Reinforcement Technology

Connecting Clamps for Reinforcements
In accordance with the German standard DIN 18014: 2014-03 Fundamenterder – Planung, Ausführung und Dokumentation (Foundation
earth electrode - Planning, execution and documentation), foundation earth electrodes have to be connected with the reinforcement of the
foundation slab at intervals of 2 metres. Of the various connection possibilities, clamp connections have turned out to be the most economic
as they can be implemented quickly and easily on site.

According to the current lightning protection standards, reinforcing steels should, among other things, be used as natural components of the
down conductor system. The table below provides an overview of the nominal and outer diameters as well as cross sections of the reinforcing
steels DIN EN 10080: 2005.
For connecting reinforcing steel meshes or reinforcements with round and flat conductors.
Arrangement: (II) = parallel (+) = cross

Nominal diameter d S Outer diameter d A

The outer diameter including corrugation is approx. d A = 1.15 x d S .

DEHNclip Rebar Clamp

Quick and safe:
DEHNclip rebar clamp for quick connection of the earth electrode to the reinforcement without tools. DEHNclip is tested for a lightning current
carrying capability of 50 kA (10/350 µs) in accordance with EN 62561-1.
