Abstract

U teorijskom dijelu diplomskog rada su se obratile teme trenutnog načina izmjere prostora i način na koji će se unaprijediti proces izrade tehničke dokumentacije. Također se dalo objašnjenje zašto je sustav 3D skenera puno korisniji od sustava koji se koristio prije. Potom su se objasnili koje su mogućnosti i brzina 3D skenera. U teoretskom dijelu se također objasnilo šta znači pojam oblaka točaka i koji su načini izrade 3D modela od oblaka točaka. Postoje dvije vrste izrade 3D modela iz oblaka točaka a to su raznim algoritmima odnosno automatizirani sustavi i ručni sustavi izrade modela. Zadnja dva poglavlja teoriskog dijela obuhvaća razlike između parametarskog modeliranja i tradicionalnog modeliranja i koje su prednosti i nedostaci jednog i drugo pristupa modeliranja. Zadnje veliko poglavlje u teorijskom djelu obuhvaća normu HRN EN 1090 koja objašnjava kojih se pravila mora pridržavati pri izradi konstrukcije prema normi HRN EN 1090. U praktičnom dijelu diplomskog rada objasnio se postupak skeniranja objekta na kojem će se izraditi čelična konstrukcija prema normi HRN EN 1090. Nakon skeniranog prostora detaljno se objašnjava kako od oblaka točaka dobije 3D model objekta pomoću kojeg će se postaviti čelična konstrukcija. U sljedećem poglavlju detaljno se objašnjava izrada čelične konstrukcije. Posebna pažnja se posvećuje postavljanju čelične konstrukcije unutar prostora građevina di je bilo nekoličina problema zbog manjka prostora. Također se jako detaljno objasnilo oblikovanje spojeva koji su bili potrebni za izradu čelične konstrukcije i njihova propagacija kroz cijelu konstrukciju. Zadnji dio što se tiče izrade konstrukcije se objasnilo kako pomoću programa Advance Steel dobiti kompletan popis materijala i cijelu tehničku dokumentaciju. U zadnjem dijelu praktičnog dijela objasnili su se neka pravila norme HRN EN 1090 pomoću koje su se oblikovali dijelovi čelične konstrukcije. Napravljena je i specifikacija postupka zavarivanja za jedan zavar na konstrukciji pomoću kojeg se objasnilo kako doći do parametara zavarivanja. Na kraju diplomskog rada se prikazala završena čelična konstrukcija unutar objekta i dao se zaključak o prednostima i nedostacima ovakvog sustava izrade konstrukcija.

Abstract (english)

In the theoretical part of the thesis, the topics of the current way of measuring space and ways to improve the process of creating technical documentation were discussed. An explanation was also given as to why the 3D scanner system is much more useful than the system used before. Then it was explained the capabilities and speed of the 3D scanner. In the theoretical part, it was also explained what the term point cloud means and what are the ways to create a 3D model from a point cloud. There are two types of 3D model creation from point clouds, namely manual model creation and automated systems using various algorithms. The last two chapters of the theoretical part cover the differences between parametric modeling and traditional modeling and what are the advantages and disadvantages of both modeling approaches. The last large chapter in the theoretical part includes the HRN EN 1090 norm, which explains which rules must be followed when making a structure according to the HRN EN 1090 norm. In the practical part of the thesis, the scanning procedure of the object on which the structure will be made according to the HRN EN 1090 norm was explained. After the scanned area, it is explained in detail how to obtain a 3D model of the object from the point cloud, which will be used to position the steel structure. The next chapter explains in detail the construction of the structure. Special attention is paid to the installation of the steel structure inside the buildings, where there were several problems due to the lack of space. It was also explained in great detail the formation of the joints that were necessary for the production of the steel structure and their propagation throughout the entire structure. The last part regarding the creation of the structure explained how to obtain a complete list of materials and the entire technical documentation using the Advance Steel program. In the last part of the practical part, some rules of the HRN EN 1090 standard were explained, which were used to shape the parts of the steel structure. A specification of the welding procedure for one weld on the structure was also created, which explained how to reach the welding parameters. At the end of the thesis, the completed steel structure inside the building was presented and a conclusion was given on the advantages and disadvantages of this system of construction.
