再將避雷針立起 , 找直、找正后 , 進(jìn)行點焊 , 然后加以校正 , 焊上其他三塊脅板。后面將引下線焊接在底板上 , 清理藥皮刷防銹漆。支座和支架，水平間距為1-1. 5m，轉(zhuǎn)彎處為0. 25m-0. 5m。引下線的上端與避雷帶（網(wǎng)）的交接處，應(yīng)彎曲成弧形再與避雷帶（網(wǎng)）并齊進(jìn)行搭接焊接。不同平面的避雷帶（網(wǎng)）應(yīng)至少有兩處互相連接，連接應(yīng)采用焊接。建筑物屋頂上的突出金屬物體，如旗桿、透氣管、鐵欄桿、爬梯、冷卻水塔、電視天線桿等，這些部位的金屬導(dǎo)體都必須與避雷帶（網(wǎng)）焊接成一體。避雷帶通過伸縮沉降縫的做法：應(yīng)將避雷帶向側(cè)面彎成半徑為100mm的弧形，且支持卡子中心距建筑物邊緣距離減至400mm，可以將避雷帶向下部彎曲。避雷針安裝時應(yīng)在建筑物首層起每三層設(shè)均壓環(huán)一圈?？蓪⒔Y(jié)構(gòu)圈梁鋼筋與柱內(nèi)充當(dāng)引下線的鋼筋進(jìn)行連接（綁扎或焊接）作為均壓環(huán)。沒有組合柱和圈梁的建筑物，潛江橋梁避雷針加工廠家，應(yīng)每三層在建筑物外墻內(nèi)敷設(shè)一圈12mm鍍鋅圓鋼作為均壓環(huán)，并與防雷裝置的所有引下線連接，潛江橋梁避雷針加工廠家，潛江橋梁避雷針加工廠家。</span>

style="font-size:16px;">據(jù)中國的規(guī)范規(guī)定，單支避雷針的保護(hù)范圍是一個錐體，高度為h的避雷針，其在地面上的保護(hù)半徑r=1.5h；在被保護(hù)物高度hx的水平面上，其保護(hù)半徑rx為：rx=(1.5h-2hx)P。 “折線法”是比較成熟的方法，在電力系統(tǒng)又稱“規(guī)程法”，即單支避雷針的保護(hù)范圍是一個以避雷針為軸的折線圓錐體。單支避雷針的保護(hù)范圍在DL/T620-997《交流電氣裝置的過電壓保護(hù)和絕緣配合》標(biāo)準(zhǔn)中有所規(guī)定；“滾球法”是國際電工會（IEC）推薦的接閃器保護(hù)范圍計算方法之一。我國建筑防雷規(guī)范GB50057-1994Z中也把“滾球法”強(qiáng)制作為計算避雷針保護(hù)范圍的方法。滾球法是以hR為半徑的一個球體沿需要防止擊雷的部位滾動，當(dāng)球體只觸及接閃器（包括被用作接閃器的金屬物）或只觸及接閃器和地面（包括與大地接觸并能承受雷擊的金屬物），而不觸及需要保護(hù)的部位時，則該部分就得到接閃器的保護(hù)。</span>

src="https://tyunfile.71360.com/UploadFile/hbqysf/637232513374384766/628387.jpg"></div><h2> 避雷針是什么樣子？ </h2> <p> <span style="font-size:16px;">避雷針是保護(hù)建筑物等避免雷擊的裝置。在高大建筑物頂端安裝一個金屬棒，用金屬線與埋在地下的一塊金屬板連接起來，利用金屬棒的前列放電，使云層所帶的電和地上的電逐漸中和。唐代《炙轂子》一書在記載了這樣一件事：漢朝時柏梁殿遭到火災(zāi)，一位巫師建議，將一塊魚尾形狀的銅瓦放在層頂上，就可以主防止雷電所引起的天火。屋頂上所設(shè)置的魚尾開頭的瓦飾，實際上兼作避雷之用，可認(rèn)為是現(xiàn)代避雷針的雛形。而早在以前，中國已經(jīng)有了避雷針，一般以**為裝飾，龍嘴里有避雷針頭。法國旅行家卡勃里歐別·戴馬甘蘭1688年所著的《中國新事》一書中記有：中國屋脊兩頭，都有一個仰起的**，龍口吐出曲折的金屬舌頭，伸向天空，舌根連結(jié)一根細(xì)的鐵絲，直通地下。這種奇妙的裝置，在發(fā)生雷電的時刻就大顯神通，若雷電擊中了屋宇，電流就會從龍舌沿線睛行至地底，避免雷電擊毀建筑物。這說明，中國古代建筑上的如雷裝置，在大批量和結(jié)構(gòu)上已和現(xiàn)代避雷針基本相似。</span> </p><h2> 常規(guī)防雷電?？煞譃榉乐睋衾纂?、防感應(yīng)雷電和綜合性防雷電。 </h2> <p> <span style="font-size:16px;">防直擊雷電的避雷裝置一般由三部分組成，即接閃器、引下線和接地體；接閃器又分為避雷針、避雷線、避雷帶、避雷網(wǎng)。以避雷針作為接閃器的防雷電原理是：避雷針通過導(dǎo)線接入地下，與地面形成等電位差，利用自身的高度，使電場強(qiáng)度增加到極限值的雷電云電場發(fā)生畸變，開始電離并下行先導(dǎo)屬放電；避雷針在強(qiáng)電場作用下產(chǎn)生前列放電，形成向上先導(dǎo)放電。兩者會合形成雷電通路，隨之瀉入大地，達(dá)到避雷效果。實際上，避雷針是引雷針，可將周圍的雷電引來并提前放電，將雷電電流通過自身的接地導(dǎo)體傳向地面，避免保護(hù)對象直接遭雷擊。參考資料來源：百度百科——避雷針</span>

style="font-size:16px;">用什么原理才不會被雷擊中避雷針從原理百上講，不是避雷，而是引雷，是引雷針。正是因為它比被保護(hù)物高，雷電流通過較高的避雷針入地，釋放較高的雷電壓，才使比避雷針低的建筑物或設(shè)度備不會被雷擊中，從而保護(hù)設(shè)備或建筑物的安全。知一般來說，避雷針越高，保護(hù)范圍就越大，保護(hù)效果也越好，但考慮到避雷針建設(shè)的安全性和經(jīng)濟(jì)性，避雷針大多建設(shè)在35米-45米之間。道用幾根避雷針，要看需要保護(hù)多大的范圍，如果需要保護(hù)的范圍較大，則專需要的避雷針數(shù)量就多，需要保護(hù)的范圍屬較小，則需要的避雷針數(shù)量就少，甚至1根就夠了。具體安裝數(shù)量，要通過計算及繪制避雷針保護(hù)范圍圖來確定。</span>

style="font-size:16px;">避雷針是由美國科學(xué)家富蘭克林發(fā)明的富蘭克林在研究閃電與人工摩擦產(chǎn)生的電的一致性時，他就從兩者的類比中作出過這樣的推測：既然人工產(chǎn)生的電能被前列吸收，那么閃電也能被前列吸收。他由此設(shè)計了風(fēng)箏實驗，而風(fēng)箏實驗的成功反過來又證實了他的推測。他由此設(shè)想，若能在高物上安置一種前列裝置，就有可能把雷電引入地下。富蘭克林把一根數(shù)米長的細(xì)鐵棒固定在高大建筑物的頂端，在鐵棒與建筑物之間用絕緣體隔開。然后用一根導(dǎo)線與鐵棒底端連接。再將導(dǎo)線引入地下。富蘭克林把這種避雷裝置稱為避雷針。經(jīng)過試用，果然能起避雷的作用。</span>
