Modular building, prefabricated volume-module and method for production of a modular building

Abstract

The invention relates to a modular building of the type that comprises vertical frame columns (70) and a plurality of volume modules (2) prefabricated of sheet metal profiles (18-32) and being of rectangular horizontal section, which are supported by the columns (70) on two or more floor levels. The volume modules (2) are prefabricated with two frame edge beams (50) which are stronger than said sheet metal profiles (18-32) and which are horizontally extended along a respective upper end wall edge of the volume module (2) and which are on the one hand linearly connected with frame edge beams (50) of adjoining modules (2) on the same floor level and, on the other hand, connected to the columns (70) in such a manner that the horizontal position of the frame edge beams (50) relative to the columns (70) is fixed. The invention also relates to such a module and a method for manufacturing such a building.

Description

FIELD OF THE INVENTION [0001] The invention relates generally to the technical field of modular buildings and concerns on the one hand a modular building and, on the other hand, a volume module and a method for manufacturing the same. More specifically, the invention concerns modular buildings of the type having a plurality of prefabricated, essentially identical volume modules of rectangular horizontal section, which are vertically supported by vertical frame columns on a plurality of floor levels so that each of them is only loaded by its dead weight and payload. [0002] The invention makes it possible to manufacture such modular buildings using so-called lightweight construction engineering (in contrast to traditional building constructions) and with industrially prefabricated lightweight modules that require a small number of mounting operations at the building site. BACKGROUND ART [0003] WO 91 / 05118 discloses a modular building of the above type comprising a skeleton or frame co...

Benefits of technology

[0007] One object of the invention is therefore to provide a solution for modular building systems of the type stated by way of introduction, which eliminates or at least reduces the above problems.

Problems solved by technology

A drawback of this prior-art building according to WO 91 / 05118 is precisely the existence of and requirements for such torsionally rigid joints.

It is a major technical problem to satisfy all the rigidity requirements that are placed on a modular building, especially the torsionally rigid joints where different materials, forces and functions meet.

Joints belong to the most difficult problems in construction engineering.

While the problem of torsionally rigid joints is at least partially solved in SE 9404111-8, a new problem arises, viz. that the required size and cost of the horizontally stabilising façade zone rapidly increase as the number of floors in the building increases.

Besides, the solution involving a special façade zone is in itself not quite satisfactory.
