Hlavinka, Martin ; Daněk, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
This thesis submitted deals with the project of the change of the production of the semi-finished product of the console which is produced by casting from the cast iron ČSN 42 2420. The component forms the frame of the deburring machine with two electric motors with the gearbox. For the suggested production the method MAG of technology welding was chosen. Because of the given technology the new construction of the component was chosen. The welded product consists of eight parts burnt from heavy-walled sheet metals. The suggested material of the construction is steel S235JR and for welding the filler rod Weld G3Si1, diameter 1 mm is chosen. For the determination of the optimal parameters of welding the testing through the slap next to the skin weld (size a5) was made. Simultaneously with the testing the fracture areas and the weld root were examined. The suggested parameters of welding were used during the preparation of WPS. For the assembling of the component the operating schedule of welding is planned.

LABORARTORY BRNO
Krajčová, Petra ; Mléčka, Jan (referee) ; Ponešová, Barbora (advisor)
When i created material composition I took care to glare, visual axis, negative impacts (such as dust and noise from traffic) and pedestrian, as the basic unit of life in the city. I started closing block. The building looked so huge. Cultural institution as a building for the people of the city should be distinguished according to their surroundings. It should be distinctive and different song structures, and the whole expression. In the past, such constructions rendition of the very place of the green, where he was to build a good view from all sides. But at our place it can not be achieved. But maybe it's so good. Odhľahčenie matter was necessary, punctures the back of my yard was founded in a small square (because I separated the whole mass, and not crossing). Block concluded only visually, Justice is an open public space, linking the foliage Class Captain Jaros with greenery on Koliště. The resulting blind facades of neighboring houses is to be completed. I Dosielila 3 materials. One major, and two side gallery. I called their studies or studios. There is a possibility of accommodation. Each studio unit is equipped with a single area, is home to a small kitchen hygieniské core. The rest of the free space is intended for the use of free and creative production. Design philosophy is based on fading tangible and intangible, creating barriers while openness. Already own place is quite a contrast unbalanced. Body, massive structure made reinforced concrete columns, the forks and re-connects. Surrounds and protects your space inside himself. Protects your soul, elusive and changeable, transparent, clear and mysterious. In this way, the construction of the body and spirit of inhaling it, I tried to follow in his proposal. All buildings of antiquity were based on the human scale, multiplying different elements, modules and construction-static properties of the material. I saw the human face particular irregularity and instability, errors, we commit. We are in the life issue in various ways, but we can not always go back. Brushing. Growth. Variety.

The aim of the Diploma Thesis is elaboration of study of bridge crossing over the Svitava river and ČD railway track in Blansko. It concerns a five-pole steel beam road bridge with through-span which carries road of the third category. The static system of the construction is solved as solid-web beam of 1.3 meters height which is in three middle spans reinforced by truss construction with top chord and system of diagonals without verticals. The height of the main beam where reinforced by trusswork is 4.75 meters. The width of spans in the road axis is 18.5 + 30.525 + 44.4 + 30.525 + 18,5 metres. The bridge deck consists of steel cross beams bonded with reinforced concrete slab of 200 millimeters of thickness. The drive-through width of the roadway is 7.0 meters. The bridge is fitted with right-sided walkway placed on steel cantilevers. The walk-through width of the walkway is 3.0 meters. Material used is S355 Steel, C30/37 Concrete and S460 Steel which is used for marginal spans of the bridge. Load-bearing construction is assessed in compliance with current technical requirements laid down by European Directives, so called “Eurocodes”. The calculation of inner powers is performed using the Scia Engineer 2013.1 software.
