Abstract

Töö käigus lahendati probleem, et ettevõtte Skanfix OÜ soovib tulla turule odavama, kuid nõuetele vastava uue varikatuse süsteemiga. Projekteeritud varikatuse tõmbidega süsteem täitis ettevõtte peamise eesmärgi – süsteemi omahinnaks saadi 99,8€. Projekteerimise käigus jälgiti iga detaili funktsioonide efektiivsust ning neid eemaldati, kui polnud vajalikud. Varikatusel on universaalne kinnitussüsteem, seega on võimalik kinnitada kergelt talade külge. Konstruktsioon kannatab 12kN jõude, mis on võetud suure varuteguriga, ning suurimad mõjuvad jõud lumekoormuse korral on uutele seinakinnitustele maksimaalselt 98,1MPa, kuid valitud materjal AISI316 voolavuspiir on 250MPa, seega konstruktsioon peab vastu ka suure ohuteguriga. Tuulekoormuse oht on eemaldatud tõmbipeasse stopperkruvi asetamisega, mis takistab tõmbipeas oleva tõmbi keermetevahelist liikumist. Klaasi kallet on võimalik reguleerida liikuva lüliga alumises toes, võimalik muuta klaasi kallet 90 kraadi suhtes üles ja alla. Leiti sobiv lahendus disainile, mis on ettevõttele meelt mööda. Lõputöö eesmärk sai täidetud ning uus varikatus sai projekteeritud, mis tuli odavamam ning täitis kõik nõuded.

Abstract [en]

The design of glass canopy. During the work process a problem was solved, which allows Skanfix OÜ to enter the market with a new, but cheaper and requirement fulfilling glass canopy system. The designed glass canopy system fulfilled the main goal – the production cost of the new glass canopy system is now 99,8€. During the process of design, every part was analyzed for its functions effectiveness and they were removed, if they weren’t neccesary. The glass canopy has an universaal fixing system, which allows it to be attached to beams with ease. The build sustains 12kN of force, which is taken with a big reserve factor and the highest applied forces under snow weight are 98,1MPa. The chosen material is AISI316, which has a tensile yield strenght of 250MPa, so the build will hold even with a big reserve factor. The wind load threat has also been removed due to the new design, which has a thread stopping screw in the rod head. The screw stops the rod thread moving in the rod head. The angle of the glass is also possible to move up and down in relation to its neutral 90 degree state. A fitting solution was found for the design, which the company also liked. The goal of the thesis has been completed and the new glass canopy system has been designed, which has lower production costs and fulfilled every need.
