Handheld concrete cutter. Market research and concept development.

Šlepikas, Paulius January 2017 (has links)
In this Master’s Degree project the topic of handheld deep cutting is analysed. These days in the construction business workers face the challenge of cutting into concrete, brick and other mineralbased materials deeper than 15 cm. Currently there are a few handheld solutions for deep cutting but they have some major limitations, such as low reliability and safety, high price, maintenance and tiresome usage of these machines. In this paper the project is divided into two components – market research and concept development. To build a knowledge base, firstly, current technical platforms for handheld deep cutting machines are reviewed. Then, theoretical background behind market research and concept development is analysed. Following theoretical framework market research and concept development are implemented and steps taken described. Secondary research, customer interviews and focus groups are the main sources of information for the market research. Morphological and Pugh’s matrices are then used to generate and evaluate possible concepts, while software packages SolidWorks and KeyShot are used as tools for development of design features. Findings from the market research revealed that window, door, ventilation openings, resizing of bricks or concrete elements and fixing mistakes done during moulding are the main applications of deep cutting machines. It was noticed that most of the construction professionals are not aware of these machines, use workarounds or hire subcontractors. Single-phase electric ring saw is the outcome from product concepting stage. Three design features – toothed ring, telescopic blade guard and start switch – are then proposed. Finally, discussion of the whole project and its conclusions are given, recommendations and short overview on future work are provided. Work consists of 7 parts: introduction, frame of reference, implementation, results, discussion and conclusions, recommendations and future work, references. Thesis consists of: 68 pages of text without appendixes, 40 figures, 4 tables, 35 references. 8 appendixes attached. / I detta masterprojekt analyseras ämnet handhållen djupskärning. Nuförtiden inom byggbranchen står arbetarna inför utmaningen att skära i betong, tegel och annat mineralbaserat material som är djupare än 15 cm. För närvarande finns det ett antal handhållna lösningar för djupskärning, dock med stora begränsningar så som låg pålitlighet och säkerhet, högt pris och behov av underhåll samt tröttsam användning av dessa maskiner. I detta arbete delas projektet upp i två komponenter – marknadsundersökning och konceptutveckling. För att bygga upp en kunskapsbas granskas först nuvarande tekniska plattformar för handhållna djupskärningsmaskiner. Därefter analyseras teoretisk bakgrund om marknadsundersökning och konceptutveckling. Baserat på det teoretiska ramverket, implementeras marknadsundersökningar och konceptutveckling och genomförandet beskrivs. Sekundär forskning, kundintervjuer och fokusgrupper är de primära informationskällorna för marknadsundersökningen. Morfologiska och Pughs matriser används sedan för att generera och utvärdera möjliga koncept, medan programen SolidWorks och KeyShot används som verktyg för utveckling av designfunktioner. Resultat från marknadsundersökningen visade att fönster, dörrar, ventilationsöppningar, storlekändringar på tegelstenar eller betongelement och korrigering av defekter som uppkommit under gjutning är de huvudsakliga användningsområdena för djupskärningsmaskiner. Det noterades att de flesta byggnadsarbetarna inte är medvetna om dessa maskiner, använder improviserade lösningar eller anlitar underleverantörer. Enfasig elektrisk ringsåg är resultatet av produktkonceptionsstadiet. Tre designdetaljer – tandad ring, teleskopskärmskydd och startbrytare – föreslås därefter. Slutligen presenteras diskussion om projektet och dess slutsatser samt rekommendationer och en kort översikt över framtida arbete. Arbetet består av 7 delar: introduktion, referensram, genomförande, resultat, diskussion och slutsatser, rekommendationer och framtida arbete, referenser. Avhandlingen består av: 68 sidor text utan bilagor, 40 figurer, 4 tabeller, 35 referenser. 8 bilagor bifogade.

Modernizace bytového domu Vlhká 22, Brno / Modernization of apartment house Vlhká 22, Brno

Neduchal, Zbyněk January 2020 (has links)
The diploma thesis processes project documentation in the stage of construction for modernization of an apartment house near the center on the street Vlhká 22 in Brno. The building is divided into four residential floors and nonresidential basement and attic. On the first floor there are two residential units and the other four residential units. The foundation structures are made of solid bricks. The vertical load-bearing and non-load-bearing structures are also made of solid bricks. Exceptionally drywall partitions. In the basement, the ceiling structures are made of brick barrel vaults, above the above-ground floors there are wooden beamed ceilings. The roof structure of the building is made of purlin system with standing stool and covering of ceramic roof tiles. Three additional housing units will be built in the attic. In the basement, the masonry will be undercut by a chain saw, partly by pressure grouting and partly by a new layer with a waterproofing layer. All wood-beamed ceilings will be replaced with prefabricated ceiling beams with aerated concrete inserts without overhead slab. The garden part of the building will be insulated with mineral wool. The roof structure will be constructed from the street side as a shed roof and in the garden part a flat roof with a gradient layer of expanded polystyrene thermal insulation and a waterproofing layer of thermoplastic poleolefin.
