100mmx 100mm的孔洞，且洞口的大小里外一致。直線段支架的水平間距應(yīng)為1-1.5m，垂直間距應(yīng)為1.5-2m，且支架間距應(yīng)該平均分布。女兒墻上設(shè)置的支架應(yīng)該與墻頂面垂直。 (3)在屋脊或檐口支座、支架上的安裝需要使用混凝土支座或支架固定?，F(xiàn)場澆制支座的時(shí)候，首先把脊瓦敲去一角，使支座與脊瓦內(nèi)的砂漿連成一體；固定支架時(shí)，用電鉆將脊瓦鉆孔，再將支架插入孔內(nèi)，用水泥砂漿填塞牢固。支座和支架的水平間距為1-1.5m，轉(zhuǎn)彎處為0.25m-0.5m。</span>

——★1避雷針是利用前列放電的原理，吸收雷電達(dá)到保護(hù)復(fù)作用。避雷針是保護(hù)某一片區(qū)域的，所以設(shè)置高度很高（具體高度，需要根據(jù)保護(hù)面積作復(fù)雜的計(jì)算），并且要有很高的強(qiáng)度要求，可以很好的吸收【直擊雷】的放電。 ——★2、建筑物避雷帶的避雷原理同避雷針相同，但是： ①、保護(hù)目的為建筑物自己，因此不制需要特別的高度等質(zhì)量要求； ②、一般的建筑物遭受直擊雷的可能性極低（高層建筑除外），主要防止【感應(yīng)雷】對建筑物的損害，一百般避雷帶足以滿足要求。 ——★3、直擊雷與感應(yīng)雷的區(qū)別： ①、直擊雷就是雷電直接與地面物體放電，釋放能量； ②、距離帶電云彩較近的建筑物，會度積聚與帶電云彩相反極性的、相同數(shù)量的電荷，當(dāng)帶電云彩突然失去電荷（如云彩之間放電），積聚在建筑物上的電荷就失去吸引力而四處泄放，這就是感應(yīng)雷。對于避雷針的材料，有很多種</span> 十堰建筑避雷針檢測避雷針價(jià)格，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)優(yōu)良值得推薦！</p><div

15～20mm、長度為1～2m的圓鋼或鋼管，固定于支柱上端經(jīng)接地引下線與接地體連接。在雷雨天氣，高樓上空出現(xiàn)帶電云層時(shí)，避雷針和高樓頂部都被感應(yīng)上大量電荷，由于避雷針針頭是尖的，所以靜電感應(yīng)時(shí)，導(dǎo)體前列總是聚集了多百的電荷。這樣，避雷針就聚集了大部分電荷。避雷針又與這些帶電云層形成了一個(gè)電容器，由于它較尖，即這個(gè)電容器的兩極板正對面積很小，電容也就很小，也就是說它所能容納的電荷很少。而它又聚集了大部分電荷，所以，當(dāng)云層上度電荷較多時(shí)，避雷針與云層之間的空氣就很容易被擊穿，成問為導(dǎo)體。這樣，帶電云層與避雷針形成通路，而避雷針又是接地的，避雷針就可以把云層上的電荷導(dǎo)入大地，使其不對高層建筑構(gòu)成危險(xiǎn)，保證了它的安全。帶電的云，首先是從上往下運(yùn)行,在高處安避雷針，就首先將云中的電放答掉,以后到房子接觸云的時(shí)候，就基本沒有或只有少部分電而沒有危險(xiǎn)了</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(gè)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(shí)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(shí)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(gè)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(shí)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>
