Description
Technical field
The present invention relates to light-weighted and can resist the compound earth brace and its manufacturing method of temperature change.
Background technique
In general, thunderbolt is the strong electric discharge phenomena because caused by active air-flow flows between cloud and ground, Xiang Di
Surface discharges powerful electric current.Thunderbolt has huge destructive power, therefore when building various facility objects, has to setting ground connection
Device, quickly to ground discharge, to prevent loss caused by thunderbolt in thunderbolt.
Also, to the dash current that greatly safely guidance thunderbolt generates, building fire, building caused by preventing because of thunderbolt
Object damages and human loss.The high voltage that thunder resisting equipment is used to generate thunderbolt imports underground, including lightning rod (connects sudden strain of a muscle day
Line), and the earthing or grounding means (earth brace) for accessing underground simultaneously, earthing or grounding means are connect with lightning rod by lightning-arrest electric wire (conducting wire)
(earth brace) is electrically connected equipment with the earth, and the surge voltage that will flow into thunderbolt of equipment etc. imports the earth, prevents because of impact electricity
Equipment caused by pressure is damaged, while protecting life security.
In recent years, earth brace is applied not only to lightning protection, is also used to electrically set electronic instrument, communication device, metering device etc.
The overload generated in standby system imports the earth, to protect tip device, prevents the maloperation of tip device.
In South Korea, Japan, China, general grounding technology is similar at present, by adding electric conductivity material in concrete
Material assigns electric conductivity, and the shape of bar or plate is made.
However, the ground structure of the concrete using traditional imparting electric conductivity, not can solve concrete property bring
Problem, in storage or transportable concrete product process, because the slight crack etc. of concrete product will cause the loss of commodity value.
Also, concrete ground structure is generally made of internal core material and external conductive material, however its main accessories,
I.e. electric current induction core material is different with the expansion rate of electrically conductive concrete, can be because the difference of temperature causes internal core material and outside to lead
The relaxation of electric material.

The inner side and outer side of core material (100).Conducting concrete (200) may include Portland cement, carbon fiber and steel fibre.Conduction is mixed
Solidifying soil (200) can also include other substances in addition to the foregoing.
The carbon fiber and steel fibre that conducting concrete (200) includes are mixed with concrete.Carbon fiber and steel fibre
Have the effect of enhancing concrete hardness, carbon fiber and steel fibre are adhering closely in electric current induction core material (100), different when flowing into
It, can be rapidly to ground discharge when normal electric current.
Graphite can be used in the carbon fiber that conducting concrete (200) includes.The hardness of graphite enhances with the raising of temperature,
2500 DEG C at a temperature of, hardness is than enhancing about 2 times under room temperature.And graphite have low thermal expansion, good conductivity it is excellent
Point.
It is conductive mixed can rapidly to discharge inflow because of the characteristic of itself for the graphite for including inside conducting concrete (200)
The internal electric current of solidifying soil (200), even if at high temperature, because expansion rate is low, conducting concrete (200) inside can also be reduced
Damage ratio.
