Adhesion of Adhesive Joints for Facade Applications Made of Wood-based Materials
Nečasová, Barbora ; Schmid, Pavel (referee) ; Sedlák,, Petr (referee) ; Kovářová, Barbora (advisor)
The presented dissertation thesis is focused on investigating the adhesive properties of façade cladding made of wood and wood-based materials in combination with flexible adhesion/assembly systems. The systems allow the implementation of effective construction joints and provide a solution with uniform stress distribution which allows the transfer of heavy loads, while simultaneously reducing the weight of the entire structure, which is also often connected with substantial cost reductions. Despite all that, little attention has been paid to this area so far. It is not a solution which is properly embodied in technical standards or in designers´, architects´ and contractors´ awarenesses. The aim of this dissertation is to characterise adhesive properties of selected façade cladding representatives made of wood and wood-based materials for the purposes of bonded joint application in a ventilated façade system. To define adhesion of façade joints, numerical and experimental methods are used, taking also various limit conditions into account. The main conclusion of the dissertation is the characterisation of basic parameters which influence adhesion, effectiveness and quality of façade glued joints. The secondary conclusion is the compilation of a simple methodical procedure for testing and implementing façade glued joints. The dissertation also makes a contribution by extending the current state of knowledge of façade adhesive joints.

Project planning and management of construction residential houses in the file Štětí
Sládek, Lukáš ; Hanzelková, Martina (referee) ; Šlanhof, Jiří (advisor)
The subject of this thesis is the preparation and organization of construction of residential buildings in Štětí. In the technological regulations deal with all the layers of flooring from the ceiling construction in residential buildings. The objects are hard floors. For floor coverings will be used PVC roofing, ceramic tiles and concrete coating. It will be used for machining of concrete. Next, I will discuss technological instruction, timing, valuation of all technological stages, construction site equipment, health and safety at work. Also here describe the proper allocation of construction processes into sub-processes to technological stage of completion of work most effectively achieve the objective.

Repair of surface sliding
Teplý, Miroslav ; Vyplašil, Evžen (referee) ; Kubíček, Jaroslav (advisor)
The selection of suitable materials for the renovation of sliding shafts requires a comparison of several criteria. The main criteria were selected size shear strength under tensile stress lap bonded assemblies, resistance to adhesive wear and economic criteria. From the results of all tests is selected the most suitable friction material to repair worn out places of shaft. The technological process of sealing the shaft was drawn up on the basis of the literature, recommendations supplier of sliding materials and their own experience.

Repair of machinery
Teplý, Miroslav ; Kovář, Petr (referee) ; Kubíček, Jaroslav (advisor)
Theme of this Bachelor´s thesis deal with problems of repair of machinery - repair the shaft. The thesis is divided into two parts. The first part deals with the possibility of using thermal spraying for the renovation of the shaft surface at the point of contact with the shaft seal ring. The second part deals with the use of epoxy putty for the renovation of the shaft surface at the imposition of a bearing.

Vliv huminových kyselin na půdní strukturu
KLENOTOVÁ, Eva
Soil structure is one of the indicators of soil quality. A crumbly structure is a soil with the best characteristics. Its formation is influenced by a whole range of physical, chemical, and biological factors. In the bachelor thesis was examined the effect of humic acids as sealants on soil aggregation. From three obtained solutions from different sources was chosen for the subsequent experiments the best quality source of humic acids. For the determination of aggregates amount was used a comparison of two methods, dry sieving and wet sieving. The result was a conclusive finding of the influence of humic acids on the formation of water-stable macroaggregates, which are the most important indicators in terms of soil aggregation. Furthermore, the effect of the concentration of humic acids on aggregation was confirmed. Higher concentration meant greater formation of macroaggregates. The effect of application rate of the solution on the soil structure has not been surprisingly proved.

Tensional Properties of Sealants in Cement-Based Material Sealing
Boháček, Adam ; Brandtner, Michal
The article deals with sealing of cement-based materials and tensile properties of the sealed joint. Aquapanel cement board was chosen as the base material, which was treated with a primer. Then two sealants were applied, one representative of acrylic and one of polyurethane sealants. After curing, the resulting test specimens were tested according to the valid European standard ČSN EN ISO 8340, which defines the parameters of the test specimen and subsequent test procedures. The evaluation of the test, which took place visually and with a caliper measurement, showed that only polyurethane sealant could be recommended for sealing Aquapanel. This putty, unlike acrylic putty, did not show any defects after the test, so it can be stated as suitable for sealing Aquapanel cement board.
