Modular homes, pavilions and container buildings on ground screws
23.12.2014Modern foundation construction is playing an increasingly important role in architecture. Ground screws enable an entirely new, time- and cost-efficient construction method without the need for excavations or concrete. The ground screws are setting a new benchmark in all soil classes, including difficult-to-loosen rock. Krinner Schraubfundamente GmbH from Lower Bavaria, Germany, successfully inserts vertically what has long functioned horizontally in walls. The easy installation allows solutions with a high construction quality. KRINNER's galvanized screws, for example, can provide quick and cost-effective foundations for container buildings or modular housing systems that are in harmony with nature and the environment. At the BAU 2015 trade fair in Munich, Krinner Schraubfundamente GmbH from Straßkirchen in Lower Bavaria, Germany, is presenting its latest foundation construction systems and machines from 19 to 24 January at Booth 337 in Hall A2.
KRINNER offers solutions that are tailored to customer needs. The screws are driven into the ground with special machines in accordance with the soil conditions and the size of the foundations – this is quick and one hundred percent environmentally friendly, as complex concreting is not necessary. “It’s also easy to use our machines in sensitive and challenging construction environments without compromising the environment in any way,” explains Johann Dirscherl from the German sales division. The galvanized screws, which vary between 55 centimetres and five metres in length, can also be easily screwed out of the ground when dismantling temporary structures. The screws can then be either reused or disposed of as scrap metal.
Modular homes on solid foundations
For example, 138 modular building elements for on old people’s home in Lenzburg were supported on 1,450 ground screws. Despite the very inhomogeneous subsoil, KRINNER succeeded in screwing the 1.5- to 3.5-metre-long screws into the ground within just a few weeks. This enabled the entire site environment to remain undamaged in its original condition. No surface areas were sealed, which ensured optimum rainwater management.
School container complex installed in record time
It was also decided to dispense with the laborious concreting of foundations in Pforzheim. School students and teachers there required temporary accommodation while the school building underwent general refurbishment. Because the only time available was during the six-week summer holidays, the foundations had to be installed in as short a time as possible. 150 three-storey container buildings with a total area of 1,000 m2 were supported on 440 ground screws, whereby the foundation structure had to overcome height differences in the terrain profile of up to 1.60 metres.
Art, culture and design on sustainable ground screws
Whether for container buildings that are dismantled again after months or years, or buildings where there is a particular focus on sustainability – the ground screw is suitable in both cases. In Bodelshausen near Tübingen, an exhibition and conference building has been constructed on KRINNER ground screws. The modern building, which is designed with an innovative glass and timber structure, is surrounded by wide terraces and access routes, whereby considerable inclinations across the site had to be balanced out. The client wanted not only a bespoke concept but also an environmentally friendly method of construction and a building that is in harmony with nature.
