Bleskozvod je vyn\u00e1lezom <\/strong>Benjamina Franklina<\/a> a\u00a0jeho p\u00f4vod siaha a\u017e do roku 1749. U\u017e zo samotn\u00e9ho n\u00e1zvu vypl\u00fdva, \u017ee jeho \u00falohou je nasmerova\u0165 v\u00fdboj blesku do zeme presne vyt\u00fd\u010denou trasou bez toho, aby po\u0161kodil stavbu.<\/strong> A\u00a0aj ke\u010f n\u00e1m nezaru\u010duje stopercentn\u00fa ochranu pred \u00fa\u010dinkami blesku, dok\u00e1\u017ee v\u00fdrazne eliminova\u0165 jeho mo\u017en\u00fd dosah<\/strong>, a\u00a0t\u00fdm aj pred\u00eds\u0165 zna\u010dn\u00fdm \u0161kod\u00e1m na majetku \u010di na \u017eivotoch. <\/p>\n\n\n\n

Spr\u00e1vna funk\u010dnos\u0165\nbleskozvodu z\u00e1vis\u00ed nielen od jeho odbornej in\u0161tal\u00e1cie<\/strong>, ale v\u00fdrazn\u00fd vplyv m\u00e1\nu\u017e jeho napl\u00e1novanie<\/strong>\nv projektovej dokument\u00e1cii k objektu.

Bleskozvod tvoria 3\nz\u00e1kladn\u00e9 \u010dasti: zachyt\u00e1vacia s\u00fastava, s\u00fastava zvodov a \u010das\u0165 uzemnenia<\/strong>.\nZachyt\u00e1vacia s\u00fastava<\/strong>, ako aj zvody\nsmeruj\u00face k uzemneniu s\u00fa v\u00e4\u010d\u0161inou vyr\u00e1ban\u00e9 z pozinkovanej ocele, medi\nalebo zliatin hlin\u00edka \u010di nerezovej ocele. <\/p>\n\n\n\n
