Možnosti využití kameniva na bázi odpadní skleněné moučky v novodobých stavebních materiálech / Possibilities of utilization of aggregate based on glass powder in new building materialsNovák, Jakub January 2018 (has links)
The diploma thesis deals with the use of waste glass powder as an aggregate in thermal insulation plasters for AAC. In the theoretical part, the problem of thermal protection of buildings is discussed first. The production and properties of foamed glass are described. Then the research of plasters, their composition and properties was made. Thermal-insulating plasters are specified and their use has been proposed for thermal insulation of building structures. In the practical part, suitable formulations have been proposed in the form of dry plaster and mortar mixtures (SOMS). Test samples were prepared from them. The physical and mechanical properties were measured. These were compared with the requirements set by standards and technical regulations. To get closer to the behavior of plasters on real buildings an AAC wall was built. The individual recipes were applied on it. It was monitored working with plaster and how it held on the masonry. During ripening crack development was observed. Optimization calculation inculded these aspects and it determined the optimal recipe. All designed recipes can be used as a thermal-insulating plasters.

Diagnostika točivých elektrických strojů / Diagnostics of rotating electric machinesSoukup, Patrik January 2018 (has links)
The thesis Diagnostics of rotating electric machines deals with the theory of diagnostics of rotating machines, focusing especially on the diagnosis of asynchronous motors of high power. Due to the importance of maintaining the trouble-free condition of these machines with regard to serviceability, the importance of their diagnosis is growing. Due to inappropriate working conditions or for many other reasons, different types of malfunctions may occur in the machine. The list and the way of occurrence of possible failures are included and explained in this thesis. With the growing age of the machine, it is important to check the insulation status through insulation testing. These tests are performed in the practical part of the thesis and the results are presented. In the case of asynchronous machines, each anomaly leaves a signature in the form of an electrical, magnetic or vibrational signal. These signals are analyzed and evaluated using a specific measuring equipment with the intention of deciding on the current state of the machine. Motor current signature analysis (MCSA) is considered to be the main diagnostic method of asynchronous machines in this thesis. This method is described in detail in this paper and is being applied in electrical engineering.

Měření elektrických parametrů vysokonapěťových komponentů pomocí elektronického můstku / Measurement of HV equipments by electronic bridge.Kumičák, Ivan January 2019 (has links)
The main idea of this thesis is measurements of dielectric materials by using a device Tettex. The thesis is about basic physic properties of dielectric materials. The determination of a dielectric material is considered. The behavior of these materials in electrical fields and reasons, those can have an influence on it, are considered as well. In the text are described measuring methods of chosen parameters of dielectric materials by device Tettex and its functional principles. There are an evaluation of measurements, which were done, and a discussion about achieved results.

Pavilon šelem v zoologické zahradě Lešná / The pavilion in the zoo LešnáPetrík, Tomáš January 2013 (has links)
The subject of the diploma thesis is a processed design of a steel construction of a pavilion shaped by spherical segments. The pavilion has exhibition purpose as a part of the zoological garden Lešná, and is intended for African beasts. The design meets architectonical requests - roundness and luminosity. A shape of the pavilion consists of three intersecting cupolas with a frontal curved cut out for glass facade. Construction of the pavilion consists of the radial arranged arched ribs with transversal bars, which are supplemented by horizontal purlins. Forehead of the pavilion is formed by columns and girts. Cladding is designed in combination: aluminum profile and insulated glass. Comparison of alternative steel structure solutions is also a part of the diploma thesis.

Vinařství Havraníky / Viniculture in HavraníkyKrátká, Kristýna January 2022 (has links)
The diploma thesis aims to elaborate on the project documentation of the buildings SO 01 - hotel and SO 02 - a winery within the complex of Viniculture Havraníky, a former agricultural area. SO 01 is a two-storey building with a partial basement. There is accommodation for 50 guests, a restaurant and a wine bar. SO 02 is a single-storey building with a basement. It consists of all operations for the production of a medium-sized winery. The structural system of both buildings is designed as a cast-in-place concrete frame. Fasade is insulated with an external thermal insulation system (ETICS). The roofing of the SO 01 building is solved by a flat green roof, whereas the roofing of the SO 02 building s solved by a saddle roof with girders.

Možnosti využití různých druhů popílků při výrobě oxidovaných asfaltových izolačních pásů / Possibilities of utilisation different types of fly ashes in the production of oxidized asphalt insulation stripsSklenářová, Radka January 2019 (has links)
Reducing the impact of modern industrial production on the environment and reducing the waste generated is undoubtedly one of the most discussed topics of the present time. In the production of fossil-fueled electricity, a large amount of fine-grained waste fly ash is generated. The possible use of ash as secondary raw materials in the construction and building materials industry is one of the many environmental challenges that the energy industry is concerned with. The aim of this diploma thesis was to verify possibilities of utilization of different kinds of power station fly ash as filler in asphalt mixtures for the production of oxidized asphalt insulation strips. The main emphasis was put on the clarification of the influence of the properties of the different types of fly ashes on the resulting rheological behavior of the mixture of asphalt binder and power fly ash, which is professionally called mastic. Mastic forms a technology-critical insulating layer in the asphalt insulation strip. The prediction of the rheological properties and therefore the workability of mastic appears to be an essential element in the management of production, especially under the conditions of the variability of input raw materials. In order to solve the assigned task it was necessary to perform detailed analyzes of fly ash properties, to select the corresponding quantification variable for assessment of the mastic processability and to find the signal fly ash properties, which appears to be a control parameter of workability. As a suitable method for assessing the processability of mastic, a shear viscosity measurement method was chosen. On the basis of the findings, it is possible to state that the use of fly ash from the production of oxidized asphalt bands is not recommended as the mastic prepared from these fly ashes are unprocessed at the assumed concentrations. The negative effect of fly ash after denitrification on the mastic processability has not been demonstrated.
