The glass shepherd
Dohnalová, Tea ; Fajnor, Richard (referee) ; Gabriel, Michal (advisor)
The topic of my thesis are menhirs. Specifically, the largest Czech menhir known as the Stone Shepherd (3200 cm). The aim of this work was to transfer the exact shape and size of this megalith and materialize it here in Brno. This goal required the use of many procedures. At the beginning there was a photo shoot, then a 3D program, 3D program editing, and slicing into contour lines. Then I projected the menhir on a wall in real size and traced it to polystyrene boards. The next step was to cut out all 104 plates on a band saw and I could go to gluing and folding the whole object. The final step was to paint the object in white. The result is a simple and clean polystyrene object. I did not cover the contour lines - I present the object in the most direct form possible. The styrofoam megalith, despite its size, is a sculpture in the interior. Ideally, I would create an installation that would create a separate, isolated space for the object.

Functional polymer foams
Hána, Tomáš ; Pospíšil, Ladislav (referee) ; Jančář, Josef (advisor)
Functional polymer foams are considered as a promising field which could potentially produce foams with added value. Specifically, functionally graded foams are materials which are expected to provide better mechanical properties while preserving low density in comparison with regular foams. In this thesis, a preparation process of such foams is designed, examination of prepared structure and comparison of mechanical properties with regular foams is performed. The obtained results are discussed and further research in this field is proposed.

Technology of injection molding of thermoplastic test specimens
Khamzin, Yersin ; Petruš, Josef (referee) ; Kučera, František (advisor)
The diploma thesis focuses on the optimization of technological parameters of plastic injection molding and the study of the influence of technological parameters on the quality of molded test specimens’ type 1A. The quality of molded parts for 3 types of polypropylene (PP) with different melt flow rate (Mosten GB 002, Mosten GB 218, Mosten MA 230) and 1 type of polystyrene (PS) (Krasten PS GP 154) was evaluated in terms of dimensional stability and weight. The contribution of software for modeling the plastic injection molding process was evaluated in this work. SOLIDWORKS Plastics software was used to optimize technological parameters. The construction of the bodies, mold and cooling system was constructed, and test bodies were produced on the basis of parameters obtained from the simulation of the injection molding process. Their quality parameters were compared with a 3D model and for each of the studied materials the optimal technological parameters were selected in terms of quality and the degree of influence of individual injection parameters on the quality of moldings was evaluated. The accordance of the results of the theoretical simulation with the real experiment was proved and a computational module independent of the optimized quality parameters, generally suitable for optimizing the quality parameters of the injected parts, was developed.

The design of ETICS using insulation core made of aerated concrete
Machala, David ; Zach,, Jiří (referee) ; Drochytka, Rostislav (advisor)
This thesis deals with theoretical suggestions of contact self-supporting insulation system with an insulating core made of porous concrete. The text prepared knowledge about ETICS system, the properties of porous concrete are thoroughly described, including the history and the most often used technology for production of porous concrete. The conclusion is made by comparison of economical and thermal insulation criteria using optimizing calculation and the applicability criteria of proposed ETICS are stated.

Administrative building Brno Hlinky, implementation of facade and roof cladding
Dušková, Lucie ; Liška, Pavel (referee) ; Kovářová, Barbora (advisor)
The subject of this Bachelor thesis is offering solution of technological steps roofing and cladding of an office building in Brno, Hlinky. It is a two storey building, partial basement, the overall module dimensions 9.4 x 37.5 m. Main supporting skeleton consists of roof trusses and ceiling beams that are attached to poles. The roof is purlin, load-bearing layer is trapezoidal sheet, which is on the top flange purlins. The walls are self-supporting, walled. Roof cladding is insulated with layer of polystyrene, the main waterproofing layer is mPVC film. Most of the cladding is designed as external thermal insulation composite systems with ceramic tiles, part of the facade on the west side of the building is made up of wood paneling with an air gap.
