Pierwszenstwo Zgloszenie ogloszono: 30.05.1972 Opis patentowy opublikowano: 20.12.1975 75605 KI. 37a,l/92 Twórca wynalazku: Lidia Boruta Uprawniony z patentu tymczasowego: Politechnika Krakowska, Kraków (Polska) Sposób zabezpieczenia antykorozyjnego konstrukcji sprezonych Przedmiotem wynalazku jest sposób zwiekszenia nosnosci konstrukcji sprezonych majacy zastosowa¬ nie w budownictwie przemyslowym i mieszka¬ niowym.Dotychczas nosnosc konstrukcji obliczalo sie ze wzgledu na stan zarysowania. Stan zarysowania jest dla konstrukcji sprezonych niszczacy, ze wzgle¬ du na to, ze poprzez rysy dostaje sie woda lub inne stymulatory korozji, co powoduje zniszcze¬ nie ciegien sprezajacych, a tym samym zniszczenie konstrukcji.Celem wynalazku jest opracowanie sposobu za¬ bezpieczenia konstrukcji przed wplywem czynni¬ ków zewnetrznych, a tym samym zwiekszenie ich nosnosci.Cel ten zostal osiagniety przez opracowanie spo¬ sobu wedlug wynalazku, w którym zastosowano powloki elastyczne zabezpieczajace konstrukcje przed wplywem czynników powodujacych korozje ciegien sprezajacych.Cecha istotna sposobu wedlug wynalazku jest to, ze na konstrukcje sprezone naklada sie ela¬ styczna powloke, przy czym powloka ta jest war¬ stwa zabezpieczajaca i sklada sie z powloki ela¬ stycznej wykonanej z abizolu R, na która jest nalozona powloka wykonana z wlókna szklanego, oraz, ze na powloke z wlókna szklanego jest na¬ lozona powloka elastyczna wykonana z abizolu P lub D, roztworu plastyfikowanych olejów asfaltów ponaftowych w rozpuszczalnikach organicznych. 15 20 25 30 Przedmiot wynalazku jest blizej wyjasniony na rysunku w przykladzie wykonania, który przedsta¬ wia przekrój poprzeczny dzwigara z nalozonymi powlokami.Na konstrukcje sprezona 1 jest nalozona war¬ stwa 2 wykonana z abizolu R. Warstwa 2 stanowi warstwe gruntujaca. Na warstwe 2 jest nalozona warstwa powloki 3 wykonanej z wlókna szklane¬ go, stanowiaca warstwe zbrojeniowa. Na warstwe powloki 3 cienkimi warstwami jest nalozona po¬ wloka 4 wykonana z abizolu P lub D. Powloka 4 zwieksza elastycznosc calej powloki.Powloki nalozone na konstrukcje posiadaja sto¬ sunkowo duza elastycznosc, w zwiazku z czym nie rozrywaja sie przy pewnych wielkosciach rys i uniemozliwiaja zniszczenie poprzez korozje cie¬ gien sprezajacych. Sposobem wedlug wynalazku mózha zwiekszyc nosnosc konstrukcji juz istnie¬ jacych, lub zmniejszyc wymiary konstrukcji pro¬ jektowanych. PLPriority Application announced: May 30, 1972 Patent description was published: December 20, 1975 75605 KI. 37a, l / 92 Inventor: Lidia Boruta Authorized by the provisional patent: Cracow University of Technology, Krakow (Poland) Method of anti-corrosion protection of prestressed structures The subject of the invention is a method of increasing the load-bearing capacity of prestressed structures, which is used in industrial and residential construction. calculated due to the scratch condition. The scratch condition is destructive for prestressed structures, due to the fact that water or other corrosion stimulants get through the cracks, which causes the destruction of the tension cables, and thus the destruction of the structure. This objective was achieved by the development of a method according to the invention, in which elastic coatings were used to protect the structure against the influence of factors causing corrosion of the prestressing tendons. An essential feature of the method according to the invention is that a prestressed structure is provided with an elastic coating, the coating being a protective layer and consisting of an elastic coating made of abizol R to which a fiberglass coating is applied, and that the fiberglass coating is applied elastic coating made of abizol P or D, a solution of plasticized asfa oils petroleum lites in organic solvents. The subject of the invention is explained in more detail in the drawing in an example of an embodiment which shows the cross-section of a spar with applied coatings. A layer 2 made of abizol R. is applied to the prestressed structure 1. The layer 2 is the primer layer. The layer 2 is provided with a coating layer 3 made of glass fiber as a reinforcement layer. A coating 4 made of abizol P or D is applied to the coating layer 3 with thin layers. The coating 4 increases the flexibility of the entire coating. Coatings applied to the structure have a relatively high flexibility, therefore they do not tear at certain crack sizes and prevent destruction by corrosion of the compression strings. According to the invention of the brain, it is a method to increase the carrying capacity of already existing structures or to reduce the dimensions of the designed structures. PL
