PPV sustav sidrenja omogućuje automatsko produbljivanje sidra u izolaciju. Tako otpada operacija glodanja/struganje izolacije sa strugačem u svrhu produbljenja sidra, već se to obavlja istovremeno s ugradnjom pičvršćivača.
Karakteristike:
kvalitetni vijčani pričvrščivać,
visoka otpornost pričvršćivača na UV zrake,
ugradnja sidra bez prethodnog glodanja izolacije za pomak glave pričvršćivača u izolaciju pomoću PPV alata,
jednostavna i brza ugradnja,
za sprječavanje toplinskih mostova (0,00 W/K),
za izravnanje površine izolacije,
moguće korištenje s pritisnim pločicama, s kojima povećavamo površinu za pričvršćivanje.
Skozi prilepljeno izolacijo v sidrno podlago izvrtamo izvrtino premera Ø8 mm. Izvrtina mora biti vsaj 25 mm globlja od dolžine pritrdila. To je potrebno zaradi same vgradnje pritrdila, da se lahko prah, ki ostane v izvrtini, potisne naprej, da je prostor za vijak, ki pri vijačenju prodre skozi sidrni del vložka. V izvrtino potisnemo plastični vložek. Glava vložka se nasloni na izolacijo. V plastični vložek vstavimo vijak ter ga
privijemo z orodjem za vgraditev. Pri tem postopku vijak vijačimo v plastični vložek, hkrati pa rezilna krona reže izolacijo okrog glave pritrdila in tako omogoča stiskanje izolacije, ki nastaja z ugrezanjem glave v izolacijo. Ko se omejilni disk na orodju za vgraditev nasloni na izolacijo, prenehamo z vijačenjem. Če nadaljujemo, pride do deformacije površine izolacije in tako posledično do neravnin na površini.
Po zaključenem vijačenju v poglobljeni del vstavimo še čep, rondela Ø70 mm, za izravnavo poglobljene toplotne izolacije nad glavo pritrdila, istočasno pa preprečimo nastanek toplotnega mostu.
POVRŠINSKO PRITRJEVANJE
Skozi izolacijo v sidrno podlago izvrtamo izvrtino premera Ø8 mm. Izvrtina mora biti vsaj 25 mm globlja od dolžine pritrdila. To je potrebno zaradi same vgradnje pritrdila, da se lahko prah, ki ostane v izvrtini, potisne naprej. Nato v izvrtino potisnemo plastični vložek. Glava vložka se nasloni na izolacijo. V plastični vložek vstavimo vijak ter ga privijemo z nastavkom torx T25, ki je vstavljen v podaljšek za vijačenje. Pri tem
postopku vijak vijačimo v plastični vložek, dokler glava pritrdila ni pritisnjena tesno ob izolacijo. Če vijačenje nadaljujemo, pride do deformacije površine izolacije ter tako posledično do neravnin na površini.
Po končanem vijačenju lahko v steblo plastičnega vložka vstavimo EPS čep Ø14*20 mm, ali vbrizgamo poliuretansko peno.
