Claims (9)
1. Postupak ispitivanja korozije betonske konstrukcije, kod kojeg spomenuta betonska konstrukcija sadrži najmanje jedan senzor koji se sastoji od metalnog elementa (1,1‘,1“) smještenog na određenoj dubini između površine betona i prvog sloja armature, spomenuti postupak je naznačen time da uključuje mjerenje korozije spomenutog metalnog elementa provođenjem:
- indukcijskog zagrijavanja spomenutog metalnog elementa (1,1‘,1“), primjenom magnetske pobude iznad površine (2a) konstrukcije (2),
- izrade najmanje jedne termografske snimke površine (2a) konstrukcije (2),
- na osnovi termografskog snimka, zaključivanja o stupnju korozije metalnog elementa (1,1‘,1“).
2. Postupak prema zahtjevu 1, naznačen time da se izradi veći broj uzastopnih termografskih snimaka nakon isključenja magnetske pobude, u cilju mjerenja promjena temperature spomenutog metalnog elementa (1,1‘,1“) tokom vremena.
3. Postupak prema zahtjevu 1, naznačen time da se izradi veći broj uzastopnih termografskih snimaka nakon isključenja magnetske pobude, kako bi se, po temperaturi, razlikovala najmanje dva metalna elementa (1,1‘,1“) vidljiva na spomenutim snimcima.
4. Postupak prema jednom od zahtjeva 1 do 3, naznačen time da se magnetska pobuda primjenjuje magnetskim poljem jakosti iznad 0,1mT, frekvencijom između 10 kHz i 1 MHz, i sa udaljenosti između 0,1 cm i 10 cm od površine (2a) konstrukcije (2).
5. Postupak prema jednom od zahtjeva 1 do 4, naznačen time da je senzor postavljen na dubini između 0,1 i 10 cm ispod površine betona.
6. Postupak prema jednom od zahtjeva 1 do 5, naznačen time da se senzor sastoji od metalnog lima paralelnog s površinom (2a) betona, i da je debljina lima između 20 i 500 mikrometara.
7. Postupak prema jednom od zahtjeva 1 do 6, naznačen time da metalni element ima površinu prikladnu za ispitivanje i lokalizaciju početka korozije, i eventualnog širenja iste.
8. Postupak prema jednom od zahtjeva 1 do 7, naznačen time da se dimenzije metalnog elementa i trajanje magnetske pobude biraju tako da dovode do povećanja njegove temperature od najmanje 2°C.
9. Postupak proizvodnje betonske konstrukcije, naznačen time da se najmanje jedan senzor koji ima metalni element postavlja u beton na određenu dubinu između površine betona i prvog sloja armature, i time da se postupak ispitivanja korozije spomenute konstrukcije provodi u skladu sa zahtjevima 1 do 8.
