The thesis is focused on studying deformation of the circular holes in the limit bending space, depending on the material type, distance from bend, the thickness of material and diameter of hole. After analyzing all necessary technological parameters was bending technology on press brake selected. An experiment for which the tools and press brake Trumpf TruBend 5170 were selected was designed and performed. Samples for the study were designed, bent and measured. The charts have been prepared for practical use in the company from measuring. In addition, simulations were processed in Ansys program and graphs were compiled to compare the main effect of the hole deformations. Two methods were chosen to prevent deformation in limit bending space. Under-cutting method by laser and method of using special Rollbend tool. In the end, economic studies for the Rollbend tool were developed instead of under-cutting hole with grinding.

Optimalizace procesu vrtání kovových materiálů vyžaduje minimální tvorbu otřepů a jednotný vzhled vrtaných děr. Cílem práce bylo pochopit roli různých klíčových faktorů, jako řezných podmínek, způsobu upnutí obrobku a geometrie vrtáku, na tvorbu otřepů při vrtání 2 mm plechů tvářené hliníkové slitiny Al99.7Mg0.5Cu-H24, za použití vrtáků o průměru 1,6 a 2 mm, pro dosažení minimalizace tvorby otřepů a zajištění jednotnosti získaných povrchů pro velký počet vrtaných děr v obrobku. Tohoto cíle bylo dosaženo provedením 3 experimentálních testů. První experimentální test byl proveden za účelem sledování vlivu řezné rychlosti a posuvu za otáčku, jakožto rozpoznaných řezných parametrů nejvýznamněji ovlivňujících tvorbu otřepů, na výsledné velikosti vzniklých otřepů a jednotnosti vrtaných děr. V druhém experimentu byl zkonstruován vakuový upínací přípravek, za účelem upnutí vrtaného hliníkového plechu a omezení prostoru pro tvorbu otřepů na výstupní straně vrtání na obrobku, a jeho vlivu na tvorbu otřepů bylo vyhodnoceno. V třetím testu byl vyhodnocen efekt rozdílných geometrií vrtáků na tvorbu otřepů, spolu s dosaženou jednotností vrtaných děr. Výsledky z prvního experimentu prokázaly, že výška a tloušťka otřepů je redukována na obou stranách vrtaného plechu za použití vyšších řezných rychlostí. Při použití vyšších posuvů byla viděna zvětšující se výška a tloušťka otřepů na obou stranách vrtání, s výjimkou výšky otřepů na vstupní straně vrtáku do obrobku, která byla minimálně snížena. Druhý experiment prokázal, že vhodně konstruovaný vakuový upínací přípravek může významně omezit vznik otřepů na výstupní straně vrtáku z obrobku. V třetím experimentu, za použití 3 břitého vrtáku a vhodně konstruovaného vakuového upínací ho přípravku, bylo dosaženo eliminace tvorby otřepů z obou stran vrtaného plechu, společně s naplněním požadavků na jednotný vzhled vrtaných děr a vysoké výrobní produktivity. Takovýto optimalizovaný proces, bez nutnosti použití přídavné operace na odstranění vzniklých otřepů, poskytuje významnou redukci výrobních nákladů. Mimoto jsou poskytnuta doporučení pro další výzkum k dosažení zlepšení ve výrobě.

This thesis sloves assessment and project insulation of a firehouse, on the expenses related to its operation.Firehouse is situated in Hruba Vrbka nr.138. The building is partly basement, has free floors and is based on concrete foundation girders. Roofing is by the tent roof. In the first part of the thesis is a theoretical introduction in the legislature, energy prices and the posibility of insulation. In the practical part of the thesis is an assessment coefficient of firehouse, evaluation of individual variants insulation and calculated simple payback period.

The theme of the diploma thesis is the preparation of project documentation for the construction of two designed buildings of the Primary School. Building plot for the planned new building is located near the existing nursery school near the center of Vracov. The campus is designed to provide basic education in a total of 18 classes with a proposed total capacity of 540 pupils. The complex consists of 4 main buildings that functionally divide individual operations. These are designed as free-standing, SO01 and SO04 objects will be two-storey, without basement. SO02 and SO03 objects as four-storey without basement. The construction system is designed as a prefabricated reinforced concrete skeleton with filling masonry from ceramic blocks to thin-walled masonry mortar. The ceiling construction consists of pre-stressed ceiling panels SPIROLL in combination with reinforced concrete. The staircases connecting the floors are designed in reinforced concrete. Vertical communication between floors will also be made possible by barrier-free passenger lifts. The roof cladding consists of a single-shell construction with thermal insulation made of EPS, the covering will be made of PVC foil weighted with a layer of peacock. The building will be insulated with a façade thermal insulation system with a ventilated gap and external surface treatment of HPL façade cladding panels. Paved pedestrian roads will be made of concrete interlocking pavement. The road for vehicle traffic will be with an asphalt surface. Parking spaces are designed from drainage concrete pavement. The project documentation was processed in ArchiCAD.

In my diploma thesis I designed a new office building in Brno. The building will function as a business incubator, so it will provide space for developing companies for favorable lease terms. While projecting the building I took into consideration future changes in dispositions. Part of the building has a basement and it has one underground and four aboveground floors. The building is designed as monolithic ferroconcrete unit and it has reinforcing perimeter walls with unit core. The ceiling is made of monolithic ferroconcrete panels. The building has flat rooftops, ventilated facade and is based on piles.

My diploma thesis is foceused on evaluation of return of the investment based on the laster insulation together with the filling of the open space and the usage of the back gained heat. For my calculation I used the real building of the basic school Františka Kupky in Dobruška. It is a typical building extended to the whole area of Czech Republic. The realization of the building was finished in 1994. I deal with more variants of more widths of the insulation system in my work. In every single draft is counted with costs for buying of the insulation and the exchange of the filling of the opern spaces. Every draft is counted with the usage of the back gained heat. The biggest benefit was found in the insulation of the 180 mm perimeter wall and the 280 mm of the roofing sytem. Windows and door had the same number of the heating 0.8 W/m2k. In the experimental calculation with the most advantages the conclusion was made that on the heat loss of thr object is the most influential the filling of the open spaces and the facilities for the back gained heat, too. Because it is a typical building, my diploma thesis could work as a background for the draft of the elimination of the heat loss at the buildings with the same shape and usage.

This thesis evaluates the influence of thermal insulation of a detached house on the expenses associated with the operation of the property. The first part describes the construction of houses from history to the present day, as well as legislation associated with the thermal insulation of buildings. The work also deals with the energy performance of buildings, energy price developments, types of thermal isolation and insulation of Houses. Thoroughly analyzes ETICS insulation systém. The second part is devoted to a particular detached house in the village Karolinka to evaluate the economic return on investment. Thermal insulation is solved in seven variants. The work includes thermal technical assessment of the condition of the original house and then heat the assessment of the options for the thermal insulation on its economic return. In conclusion, the assessment of individual variants insulation is calculated as a simple payback period.
