Description

dauernder Trockenheit ist es ratsam, die Schale aus der Wasserleitung aufzufüllen und das Erdreich feucht zu halten.In the event of permanent drought, it is advisable to fill up the bowl from the water pipe and the soil keep moist.

Die Ausstattung der Blitzschutzanlage mit einer regenfangenden Betonschale ist eine wesentliche Verbesserung des Franklin-Blitzableiters. Für ein einwandfreies funktionieren des Blitzableiters ist es Bedingung, daß sich der Erdanker in der Grundwasserschicht des Bodens befindet und einwandfrei geerdet ist, was nicht immer realisierbar ist. Dank der Verwendung der regenfangenden Schale spielen irgendwelche unterirdischen oder sonstigen Veränderungen des Grundwasserspiegels im Hinblick auf die gute Erdung der Blitzfangspitze dann keine Rolle mehr.Equipping the lightning protection system with a rain-catching concrete shell is essential Improvement of the Franklin lightning rod. It is essential for the lightning rod to function properly Condition that the ground anchor is in the groundwater layer of the soil and properly grounded is what is not always feasible. Thanks to the use of the rain-catching bowl, everyone can play underground or other changes in the water table with regard to the Good grounding of the lightning protection tip then no longer matters.

Bei der erfindungsgemäßen Blitzschutzanlage ist der Unterteil einer Blitzfangspitze 1 in einem Porzellanisolator 2 versenkt, der seinerseits in einen hohlen Mast 3 eingesetzt ist. Dieser Mast sitzt mit seinem Fuß 7 in einem Kanal 12 einer Stahlbetonschale 10, die Regenwasser auffängt und durch Kanäle 11 in ihrem Boden einem in die Erde eingebetteten Anker 6 zuführt. Der Anker 6 ist durch einen Erdleiter 4, der innerhalb eines Kanals 13 und des Mastes 3 verläuft, mit der Blitzfangspitzel verbunden. Das untere Ende des Isolators 2 berührt das obere Ende einer Asbestschicht 5, die in einer Länge von 2 m die Innenwand des Mastes 3 verkleidet. Das Unterteil des Mastes ist an drei Seiten durch in der Erde verankerte Seile 8 als Pardunenabspannung abgestützt. Mit einem Radius von 20 m umschließt den Mast ein -Zahn 9, um eine Sicherheitszone zu bilden.In the lightning protection system according to the invention, the lower part of a lightning tip 1 is in a porcelain insulator 2 sunk, which in turn is inserted into a hollow mast 3. This mast sits with his Foot 7 in a channel 12 of a reinforced concrete shell 10, which catches rainwater and through channels 11 in its Soil feeds an anchor 6 embedded in the earth. The anchor 6 is through a ground conductor 4, the runs within a channel 13 and the mast 3, connected to the lightning spike. The lower The end of the insulator 2 touches the upper end of an asbestos layer 5, which is 2 m long and the inner wall of the mast 3 disguised. The lower part of the mast is anchored in the ground on three sides 8 ropes supported as guy guying. It encloses the mast with a radius of 20 m -Tooth 9 to create a safety zone.

Claims

1 2 screw connections are provided, which use copper wires to create the conductive connection between the air-termination tip and one made of copper

1. Establish a lightning protection system in the center of the unprotected top of the floor.

Buildings, consisting of a thin-walled 5 Meanwhile, a whole series of lightning protection steel tubes screwed together mast with systems have been developed, but all of them for a fishing tip and a ground anchor, which are designed to protect individual buildings. Now is in one within the canalized towns where almost all buildings have lightning-lead concrete bases and earth conductors running along the mast are equipped, a lightning discharge is not so ter is connected to the fishing tip, which means that it is dangerous as in the countryside in agricultural leagues, that the foot (7) of the making property. There are often only the residential buildings (3) in a partially sunk into the ground, provided with lightning protection systems, and the other geals Reinforced concrete buildings such as barns, sheds and stables built on a mast foundation are usually unshell (10) sits protected, which catches the rainwater.

A method and a device for the forced "armored mast, which is expediently twice as high wise, safe triggering of the cloud discharge - like the highest object in its protection area, gen at a predetermined point was assumed by the German 5 "whose radius was between 50 and 60 m Patent 357,375 already known. This procedure will. The base of the mast sits in the center of the Ren is characterized in that the Wolkenelek reinforced concrete shell of preferably 2 to 3 m in tricity and earth electricity on an isolated diameter each, which catches the rainwater and Ladder with a correspondingly large surface area, which can be moved through channels at a depth of 2 to 3 m Spark gap-forming balance wheel 55 deten armature feeds, so that as a result of the permanent At a moderate distance from each other, moisture and conductivity in the ground are improved the. This means that one should be at the relevant point. The tall mast is the largest possible at its mast Voltage between the earth and the cloud part due to a known guy electricity reached, so at this point the flash is held and stiffened and within a radius of Derivation created artificially, so that finally 60 surrounded by a fence about 20 m. That off Lightning in this area, which is cordoned off at the desired point, serves as a safety zone against the immediate vehicle. called step voltage in the vicinity of the
