Definitions

the present invention relates to a terminal lug for the conductive connection of Equipment for reinforcing steel cast in concrete for the purpose of grounding, a corresponding Earthing system and a method for manufacturing an earthing system.
flexible connecting lugs are made of a copper conductor consist with a sleeve and this sleeve welded to a reinforcement bar.
the welding of the copper conductor to the sleeve is done with the complex CADWELD process that is carried out only by specially trained personnel can.
terminals are used to ground cables and reinforcing bars to connect with each other.
connection lug it is therefore an object of the present invention to provide a connection lug to provide the disadvantages mentioned, namely complex welding processes, special auxiliary structures, corrosion, expensive personnel and extensive documentation, avoids.
the connecting lug can easily be made with the reinforcing steel without special welding procedures welded, no specially trained personnel are required for this.
the construction company can advantageously weld the connecting lugs which the reinforcement creates.
connection lug A particularly simple solution for producing the connection lug is that Piece of reinforcing steel and the conductor by brazing or by notching using a Join notch sleeve together.
connection lug Operating earthing, equipotential bonding bars can be attached to the conductor of the connection lug or lightning protection systems, steel structures, etc. can be connected.
the basic grounding network is designed with regard to the maximum thermal Load in the event of a fault and the permissible contact voltages on the earthing system.
the competent expert is familiar with the design of earthing systems is not further explained here.
the reinforcement steel and the copper cable are connected by means of a copper notch socket 3: the reinforcement steel is connected to the notch socket by brazing (hard solder 4), the copper cable is notched.
the notch sleeve is surrounded by a shrink tube 5 beyond its ends.
Fig. 2 shows how the reinforcing bars 6, which have a length of at least 5 m and a Have a diameter of at least 10 mm, mainly with toggle joints 7 are connected. Rödel connections are approved as earth connections.
the toggle connections serve to include longitudinal reinforcements 8 greater length than that of a reinforcing bar 6, on the other hand thereby connecting the longitudinal reinforcements arranged at right angles to each other.
the individual reinforcing bars are used for reasons of better conductivity welded together (black marking in Fig. 2).
the individual welds have a length of about 5 cm.
One of the longitudinal reinforcements is continuous in parapet walls and in surrounding walls to weld.
connection lug The reinforcement steel 1 of the connection lug is welded to the continuously Reinforcement bars in at least three places 10 each about 5 cm long welded.
the connecting lug When concreting the foundation 11, the connecting lug is included the notch sleeve 3 is also cast in concrete. The notch should go after that be at least about 10 cm below the concrete surface.
the connection flags are generally arranged so that the loose end of the copper rope is as close as possible the system to be earthed (hall support, equipotential bonding rail and the like) an excess length of about 1 m.
the copper cable 2 has a pressed-on cable lug at the end and is shown in FIG. 2 led to a building wall 12 and to a potential equalization rail arranged there 13 screwed from copper.
FIG. 3 shows a connecting lug for expansion joints which is used to conductively connect two structural parts to be grounded, that is to say approximately two base plates separated by an expansion joint.
an approximately 2 m long piece of reinforcing steel 1 is fastened to an approximately 1 m long copper cable 2 with a cross-sectional area of 95 mm 2 at both ends by means of notch sockets 3 and brazing solder 4, as has already been described in FIG. 1.
the notch sleeves are in turn surrounded by a shrink tube 5.
Fig. 4 shows how the connecting lug 1, 2 on two reinforcement bars of the continuous welded longitudinal reinforcement 9 from e.g. two adjacent floor slabs both sides of the expansion joint 14 are welded.
This connection flag is suitable not only for expansion joints, but generally for connecting metal-reinforced components.
a hall support 15 is shown, the anchor screws 17 in the support foundation 18 are embedded, which has a metal reinforcement 6.
Reinforcement 6 the support foundation 18 are both the connecting lugs 31, 32 for the steel structure as well as the connecting tab 21, 22, 23 welded for the adjacent base plate.
connection flag to the base plate 19 is positioned so that the flexible copper cable 22 comes to lie in the area of the expansion joint and in the adjacent Concrete bodies 18, 19 is concreted in at least 10 cm.
the associated copper cable 22 leads up to approximately the height of the foundation anchors 16 and then goes into another piece of reinforcing steel 23 of the connecting lug.
This piece of reinforcing steel 23 extends to the lower limit of the column foundation 18 and is welded there to the metal reinforcement 6 (welding points 10). additionally the piece of reinforcing steel 23 is also welded to the foundation anchor 16 (Welding point 20).
This terminal lug 21, 22, 23 thus serves the conductive Connection of the base plate 19 to the metal reinforcement 6 of the column foundation 18.
the supports 15 are grounded via further connecting lugs 31, 32, in which the Copper rope 32 is conductively connected to the support 15.
the copper cable 32 is in the Supported foundation 18 and only then passes into a piece of reinforcing steel 31, which on the foundation anchor 16 (welding point 20) and on the metal reinforcement 6 (Welds 10) of the support foundation 18 is welded.
the metal reinforcement of the parapet wall 24 is made using a piece of reinforcing steel 25 conductively connected to the metal reinforcement 6 of the column foundation 18.
the hall floor 6 is the hall floor of a production plant with an earthing system according to the invention shown in top view.
the circumferential parapet wall 24 has a dash-dotted line continuously welded metal reinforcement 6 shown.
the hall floor exists from individual rectangular plates 34, which by means of connecting tabs 41 for expansion joints (see Fig. 4) are interconnected.
Over falling or rising earth 1 (represented by lines with a cross) are the systems to be earthed, such as the hall supports 15, with continuously welded metal reinforcements 6 connected.
the diversions 2 (represented by earthing arrows) can be in the individual Rooms in the hall (transformer room 38, electrical control room 39, hydraulic room 40) Equipotential bonding bars are connected.
an earthing mesh network smaller than 20x20 m is provided.
Two of the stage supports 35 of the stage 37 are also connected to the continuously welded earth electrode 1 Reinforcement connected.
the invention is applicable to all environmental and soil conditions, easy to document and due to the standardized material and the constant Operations can be carried out by the respective construction company without special monitoring.
connection lugs are welded.
the copper cable of the connection lug is equipped with the equipment to be earthed (steel structure, equipotential bonding bar, Lightning protection leads etc.) by means of crimped cable lugs and Screws connected.
connection lugs such as before, but used with copper cables attached to the reinforcing steel on both sides. On In this way, complex welding processes and any type of corrosion can be avoided become.
