Reinforcement Technology

For installation in concrete as a corrosion-free connection to the earth-termination system for protective equipotential bonding and / or functional equipotential bonding of the down conductor, e.g. to the reinforcement of buildings.
Please observe the following minimum screw lengths for the M10 and M12 double threads:
35 mm of M10 (thread length 40 mm)
15 mm of M12 (thread length 20 mm)

With M16 connection thread for higher current loads (50 Hz), e.g. for connecting the ring equipotential bonding system with the earth-termination systems of power installations with nominal AC voltages over 1 kV (transformer earthing).

With MV clamp made of StSt (V4A) for round conductors 8–10 mm.
Water-pressure-tight wall bushing for leading earthing conductors / equipotential bonding conductors through brickwork or walls; with M10 threaded rod made of StSt.
For subsequent installation through borehole (Ø14 mm) or through spacer in the formwork.
Test for water pressure-tightness up to 1 bar features an installation depth of 10 m in stagnant water.

For installation in the formwork.
Is suitable for water-pressure-tight wall bushings; e.g. for connecting the ring earth electrode with the equipotential bonding bar or the equipotential bonding conductor in the foundation.

Sealing collar for bushings in case of watertight foundation slabs / walls (e.g. white tank).
Water-pressure-tight for pushing on round / flat conductors with StSt tensioning straps.

Pressurised water test up to 1 bar represents an installation depth of 10 m in stagnant water, additionally tested with 5 bar compressed air according to EN 62561-5.

For connecting the reinforcement with clamping piece.
For round conductors or fixed earthing terminals with simultaneous fixing in the formwork.

Arrangement:
(II) = parallel
(+) = cross

Screwed to the fixed earthing terminal to connect, e.g. an equipotential bonding bar or structural parts such as steel girders, etc.

For connecting round and flat conductors to fixed earthing terminals with M10 / M12 thread (e.g. Part Nos. 478 011, 478 200) and M16 thread (Part No. 478 027).
Clamps with M10 thread are also suitable for installation on the rear side of the fixed earthing terminal (without connecting shaft), e.g. to connect a flat strip.

For connection to fixed earthing terminals with M10 thread, lock nut and spring washer, for use in case of perimeter insulation or thermal insulation composite systems.

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 plate at intervals of metres. Among the various connection possibilities clamping connections have turned out to be the most economic as they can be implemented quickly and easily on site.

Amongst others, reinforcing steels shall also be used as natural components of the down conductor system according to the current lightning protection standards. The table provides an overview of the nominal and outer diameters as well as the cross sections of the reinforcing steels according to DIN EN 10080: 2005 (see Figure 1).

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.

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.
