2、結(jié)構(gòu)施工時(shí)利用結(jié)構(gòu)內(nèi)鋼筋（或**型鋼）做引下線，與接地極連接，并預(yù)留與避雷帶的連接點(diǎn)； 3、裝修完成的同時(shí)，敷設(shè)避雷帶（或避雷針）。避雷針的原理：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(duì)面積很小，電容也就很小，也就是說(shuō)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(duì)高層建筑構(gòu)成危險(xiǎn)，保證了它的安全。</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(guò)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(chǎng)強(qiáng)度增加到極限值的雷電云電場(chǎng)發(fā)生畸變，開(kāi)始電離并下行先導(dǎo)屬放電；避雷針在強(qiáng)電場(chǎng)作用下產(chǎn)生前列放電，形成向上先導(dǎo)放電。兩者會(huì)合形成雷電通路，隨之瀉入大地，達(dá)到避雷效果。實(shí)際上，避雷針是引雷針，可將周圍的雷電引來(lái)并提前放電，將雷電電流通過(guò)自身的接地導(dǎo)體傳向地面，避免保護(hù)對(duì)象直接遭雷擊。參考資料來(lái)源：百度百科——避雷針</span>

style="font-size:16px;">據(jù)中國(guó)的規(guī)范規(guī)定，單支避雷針的保護(hù)范圍是一個(gè)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(gè)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(guò)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(guó)際電工會(huì)（IEC）推薦的接閃器保護(hù)范圍計(jì)算方法之一。我國(guó)建筑防雷規(guī)范GB50057-1994Z中也把“滾球法”強(qiáng)制作為計(jì)算避雷針保護(hù)范圍的方法。滾球法是以hR為半徑的一個(gè)球體沿需要防止擊雷的部位滾動(dòng)，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(shí)，則該部分就得到接閃器的保護(hù)。</span>
