DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a box-shaped, self-supporting building unit, a plurality of which may be arranged juxtaposed and/or superposed for the construction of a building, said unit comprising a self-supporting floor element and a self-supporting ceiling element, both having a supporting structure, and two pairs opposite wall elements as well as a supporting, vertical column of sectional iron in each corner, said column rigidly connecting the supporting structure of the floor element with the supporting structure of the ceiling element.
BACKGROUND ART
Building units of the above type are known having supporting walls and of which the ceiling and floor are constructed as a wooden structure supported by the walls. The known building units are constructed in accordance with traditional construction methods.
Furthermore, GB-A-2 040 334 discloses a box-shaped, self-supporting building unit comprising a bottom element consisting of a frame and a plate and an upper element consisting of a frame and a plate, and four corner columns mutually joining together the bottom element and the upper element. When the building unit is to be assembled, said elements are initially assembled to a rigid supporting frame, which is subsequently transported to the building site, at which several such building units or frames are joined together, whereafter a number of operations are to be carried out, such as fitting of inner sheating, isolation and cladding.
Finally, U.S. Pat. No. 3,442,056 discloses a prefabricated building section comprising a floor element and a ceiling element comprising profiled metal beams forming a framework about the edge of the respective elements, and a wall element comprising profiled metal beams or columns along the lateral edges thereof.
When the building section is assembled, the wall elements arranged on the floor elements at the abutting beams thereof secured to each otheer, for instance by welding. Finally, the ceiling element is arranged on top of the wall elements and the abutting beams thereof secured to each other by welding.
DISCLOSURE OF THE INVENTION
The object of the invention is to provide a method of the type stated in the introduction, which can be carried out in a rational manner and under controlled conditions regardless of the weather and the building site conditions.
For obtaining said object the building unit according to the invention is characterised by the features sates in the characterising part of claim 1.
Since the building unit consists of separate elements, it is possible to factory-prefabricate these with great accuracy in a very rational manner. Similarly, the elements forming the units may be assembled and completely mounted in the factory for formation of the finished units, which then may be transported to and assembled on site. As the wall elements can bear the ceiling element, it is possible to defer the mounting of the supporting columns, until the rest of the unit is completely assembled, whereby a the individual elements may be completed to significantly higher degree in the factory than hitherto prior to the joining together of the units on the site. It is thus possible to complete the ceiling element as well as the floor element prior to the assembly thereof and to provide the wall elements with inner sheating. As a result, the interior of the separate building units may be completed in the factory prior to the mounting on site. Overall, a substantial gain in effeciency is obtained.
According to the invention, the wall sections may be arranged abuttingly in such a manner that a vertical cavity is formed for receiving the columns.
Further, according to the invention, the supporting structure of the floor element may comprise two longitudinal bearing side members and a plurality of transverse girders arranged therebetween.
Moreover, according to the invention, the supporting structure of the ceiling element may comprise two longitudinal bearing side members and a plurality of transverse girders arranged therebetween.
