Wear analysis of the sliding surface material of large-scale hydrostatic bearings
Daněk, Lukáš ; Robenek, Dětřich (referee) ; Svoboda, Petr (advisor)
This thesis focuses on the experimental investigation of the wear behavior of sliding surface materials in large-scale hydrostatic bearings during oil supply failure. The aim is to clarify the influence of materials and surface treatments on friction and wear. For this purpose, a testing methodology was designed and implemented in laboratory conditions. An experimental module was developed for the tribometer to simulate a critical state and a new procedures were established for evaluating the behavior of the contact. Wear results were observed using a profilometer, precise scales, and a microscope. A set of suitable materials for pad sliding surfaces was created, which were tested under critical conditions. The selected materials were representatives of construction steel and anticorrosion treatments (galvanization), soft and hard (aluminium) bronzes, composite bearing linings (Babbitt), polymers (UHMWPE), and composite materials (PTFE). The experimental results show the dependence of friction on sliding velocity, wear rate, and other phenomena repeatedly measured on a statistical sample of selected materials. The final result is a list of characteristics, limitations, and recommendations for the tested sliding materials, which can be used for more effective design and operation of large-scale hydrostatic bearings.

Apartment building
Morkus, Matěj ; Blažková, Vendula (referee) ; Daněk, Lukáš (advisor)
The subject of the bachelor's thesis is the processing of project documentation for a residential building located on a plot of land in the cadastral area of Kuřim, specifically on plot number 1741, in an area with residential buildings. It is a standalone house with three above-ground floors and one underground floor. The house has eight residential units, including three 1+KK units, three 2+1 units, and two 4+KK units. The underground garage provides parking space for five cars and three motorcycles, along with a technical room and storage units. The first above-ground floor contains a stroller room, a meeting room, and two apartments, while the second and third above-ground floors have three apartments each. The property includes an access road and additional parking spaces. The house is covered with a single-ply flat roof. The basement walls and foundation structure are designed using waterproof concrete. The vertical walls in the above-ground floors are made of ceramic masonry. The work includes construction-technical documentation.

The subject of the bachelor's thesis is the processing of project documentation for the construction of an apartment building in Prostějov. The building is designed as part of a complex of four separate square-shaped buildings with a common entrance to the underground garage. There are 11 apartments planned on the above-ground floors. The basement of the building houses utility spaces and an underground collective garage. The structural system of the substructure is made of water-resistant concrete. Other vertical and horizontal load-bearing elements of the building are monolithic reinforced concrete. The roof above the garage and the residential building itself is designed as a single-layer flat roof. The thesis includes documentation for construction implementation.

The subject of the bachelor's thesis is the processing of project documentation for a new residential building in Líšeň. The residential building is designed as a five-story fully basement structure. The underground floor contains collective garages and cellar compartments. The first above-ground floor contains rental spaces. The second, third, and fourth above-ground floors consist of residential units. A total of 30 residential units have been designed. The topmost fifth above-ground floor contains studios. The building has a flat roof with a parapet. The structural system of the building is primarily skeletal, connecting reinforced concrete monolithic walls that form the load-bearing part as perimeter walls. Another structurally significant element is the structural core with an elevator shaft. The horizontal load-bearing structures consist of reinforced concrete ceiling slabs. The entire building is founded on a white tank. The bachelor's thesis includes project documentation for the construction implementation.

The bachelor thesis deals with the design and subsequent processing of the detailed project documentation for a new residential building in Uherský Brod. The residential building is located in the outskirts of the city in the Olšava housing estate. It is a detached building with three above-ground and one underground floor. In the basement there is a garage, maintenance room and technical background of the building. On the first floor there is a barrier-free apartment, cellar and joint areas. The second and third floors are reserved exclusively for residential use. In total, there are five residential units in the house with a layout of 2+kitchenette and 3+kitchenette. The structural system of the building is a cross-wall system. The base and the perimeter wall of the basement are monolithic reinforced concrete made of waterproof concrete. Vertical structures are made of brick blocks. Reinforced concrete monolithic floor slabs are designed as horizontal load-bearing structures. The roof structure is a single-skin flat vegetated roof. The building is insulated with a contact insulation system. The ventilated facade with wooden cladding is designed in parts of the third floor.

Hotel
Paulová, Iva ; Blažková, Vendula (referee) ; Daněk, Lukáš (advisor)
The aim of this master‘s thesis is the elaboration of design documentation for the construction of a hotel. The proposed detached building is located on plots in the cadastre unit of Jihlava (659673). This is a public building intended for short-term accommodation and catering. Part of the construction is a connection to the technical and transport infrastructure, specific to the locality. The building is designed as a fourteen-story building with three underground and eleven floors above ground. The floor plan shape of the object is composed of rectangles. The dominant feature are two prominent towers with ten floors above ground. There are collective garages for cars in the underground floors. The ground floor is shared by the guests and the hotel staff. The restaurant, gym, conference hall and administration are located here. The second to eleventh floor above ground contains accommodation units for guests. Excavation work is designed by thrust excavation of the construction pit. The foundation structures are designed with a foundation slab made of hydraulic reinforced concrete with deep piled foundations. In the underground floors and on the ground floor, the construction system is cast-in-place concrete frame. In the second to eleventh floor above ground, the structural system is a two-way wall systeme. The vertical supporting structures are cast-in-place reinforced concrete. The horizontal load-bearing structures and the two-armed staircases are cast-in-place reinforced concrete. The contact thermal insulation system ensures thermal insulation of the building. The building is roofed in two levels with a warm flat roof.

Car showroom
Skryjová, Adéla ; Blažková, Vendula (referee) ; Daněk, Lukáš (advisor)
The goal of this diploma thesis is to create project documentation for the construction of a car showroom on the plot parcel number 3745/28 in a cadastral territory Velké Meziříčí [779091]. It is a freestanding building setted n almost flat land. The building is partially underground. The basement is used as a wine cellar. The first floor is divided into service and car showroom. On the second floor there are only offices, a meeting room and sanitary facilities with a day room. Vertical support structures of the above-ground part of the house are monolithic, made of reinforced concrete and underground parts are load-bearing walls made of water-based concrete. Horizontal support structures are made of monolithic reinforced concrete slabs. The foundation of the object consists of reinforced concrete monolithic base slab of water-building concrete. The roof of the building is designed as a flat single-shell extensive vegetation roof. The whole building is insulated by the contact insulating system ETICS. The design also includes thermal assessment, acoustic assessment and fire safety assessment.
