Static and dynamic assessment of an outlook tower construction
Valíček, Jan ; Kala, Jiří (referee) ; Salajka, Vlastislav (advisor)
This thesis deals with static and dynamic analysis of an lookout tower construction. For dynamic analysis a computational model in ANSYS software is created. Static analysis is performed by Scia Engineer software. Both of this software use finite element method. It is also focused on wind load determination by Eurocode 1, structural factor calculation, modal analysis and vortex shedding. Verification of selected parts according to Eurocodes is included.

Analysis and comparison of wooden houses
Petláková, Lenka ; Konečná, Petra (referee) ; Aigel, Petr (advisor)
The aim of this bachelor thesis is to compare on the cost of log cabins and frame wooden constructions and descriptions technology their construction. The first part of the thesis is theoretical and it deals with prices, costs and budgets, that arise in the construction industry. Further the thesis dedicates to construction systems of wooden buildings, their history and wood as building material. Finally the theoretical part describes technology of construction of log cabin and frame wooden houses, which is completed with own photographs and time – lapse video. The second part is devoted to the analysis of the cost of selected wooden buildings. Overall the analys is realize on three log cabins from the company Sruby Masiv s. r. o., on three log cabins from Haniš sruby s. r. o., on free frame wooden buildings of Wood System s. r. o. and on free frame wooden buildings of Rovax s. r. o., prices are compared of the six log cabin and with the six wooden buildings. At first the thesis deals with the characteristics of individual wooden buildings, the calculation of ratio indicators (built-up area, built-up area, floor area and volume of woodused in wooden buildings) then adjusted prices to prices of carcass and wood built into construction. Finally, the calculated values are summarized in orderly chart, based on what cost ofbconstruction can be compared and evaluated. The conclusion evaluates the aim of the thesis. It compares the technology of construction of log cabin and frame timber construction, its time length and difficulty of construction. Finally, the conclusion deals with the results of the analysis of the cost of selected wooden buildings.

Log handling technology
Skřivánek, Tomáš ; Mergl, Václav (referee) ; Škopán, Miroslav (advisor)
The first part of this bachelor's thesis deals with the analysis of used conveyors for wooden logs. There are described the main differences and reasons for using selected conveyors. The second part deals with the design of an inclined log feeder, which is designed for logs with a diameter of up to 80 cm and a length of up to 5 meters. First, the conceptual design is described, where the procedure for the construction of the main elements of the feeder is justified. After that, the work deals with functional and capacity calculation, choosing the drive unit and selecting the chain. Further analysis are devoted to the design of the weld dimension, checking the beam deflection and checking the strength of the shaft.

Úprava pilařského provozu ŠLP v Olomučanech
Tupý, Roman
The thesis documents and analyse the current situation of the saw-mill in Olomoučany. The saw-mill was established by Školní lesní podnik Masarykův les Křtiny which is an organizational part of Mendel University in Brno. Further, alternatives of possible adjustments relating to efficiency of main saw-mill machinery, sawn wood production, the shift operation and evidence are proposed. The third part recommends optimal adjustments for current saw-mill equipment which take into account processed products and technological state of the equipment.

Návrh modernizace pily v Bojkovicích
Sommer, David
This diploma thesis titled Proposal for Modernization of the Bojkovice Sawmill deals with the analysis of the Bojkovice sawmill operation and with the proposal for the increase of production capacity. The thesis summarizes basic information about the company DATO-FOREST s.r.o., i.e. the Bojkovice sawmill. It deals with the present state of the sawmill operation, with production downtime tracking, as well as with the analysis of these problems. The practical part offers three options of these problems, proposals for the increase of production capacity, drawing documentation, and calculation of payback period. Individual solutions were compared from both economic and production effectivity point of view. One of these three options was chosen and processed in detail.

Návrh pilařského provozu rodiny Jirečků ve Svatoslavi
Novotná, Petra
This thesis describes the design of a new sawmill operation of Jireček families in Svatoslav near Třebíč. This is a proposal for operation of a particular forest property. The main requirement is to design appropriate technological arrangements, machinery and automated equipment that will meet the maximum sawing coniferous 3000 m3 per year range. The paper presents the layout of the premises Still hunting lodge where a sawmill operation to be designed, requirements analysis and calculations required values for the design of the operation, according to which the proposed machine-technological equipment and traffic arrangements. The work described processing streams with a specific variant of the machinery. Of these proposals were selected, one option that has been recommended as the most suitable. The thesis included drawings of floor plans proposed sawmills, lateral cuts recommended variants sawmills and drawings situation with the location of the building sawmills deployment and storage of logs and lumber.

Návrh pilařského provozu Diecézních lesů Hradec Králové ve Vortové
Holub, Miroslav
The diploma thesis includes a proposal for a new sawmill operation in Vortová, ORP Hlinsko, Pardubice Region for owners of surrounding forests of the Bishopric of Kralovehradecka, which manages the company with restricted constraints Diocesan forests Hradec Králové, s.r.o. On the theme the suggestion of sawmill Diocesan Forests in Hradec Králové in Vortová. The owner's request is the creation of a pilot plant project, including technology, technological arrangement, machinery of operation at the site of former premises designated for associated forestry production at Vortová no. 28. This sawmill operation must be able to carry out an annual sowing in single-shift operation of 6000 m3 spruce Round logs. The priority will be the cutting of spruce spruce logs and commercial cut to order from the logs of their own forest, until the next activity will be the cutting of foreign logs. The diploma thesis is supplemented with drawings of alternative solutions of sawmill operation and warehouses of lumber. Part of the drawing is the final recommended version of the sawmill operation. The output of the diploma thesis is the design of the sawmill operation, its incorporation according to the land disposition of the complex at Vortová, recommendations for effective and economical logging and preparation of cutouts.
