Definitions

  • Modular building, prefabricated volume-module and method for production of a modular building are fundamentally similar to Modular building, prefabricated volume-module and method for production of a modular building.
  • 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 manuf cturing 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.
  • 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.
  • WO 91/05118 discloses a modular building of the above type comprising a skeleton or frame construction consisting of vertical frame columns and horizontal bars and beams which are joined with each other in a torsionally rigid manner in joints of the frame cons- truction.
  • 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 require- ments 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. The time required at the building site for forming the joints is also an important factor.
  • SE 9404111-8 which concerns a solution to the above problems, discloses a modular multistorey building which, with respect to force take-up, is divided into on the one hand an inner zone, which takes up vertical forces and comprises frame columns with the volume modules suspended therefrom on several floor levels and which essentially does not take up any lateral forces acting on the building and, on the other hand, a facade zone, which is arranged immediately outside the inner zone and adapted to take up lateral forces for lateral stabilisation of the inner zone and hence the entire building.
  • the facade zone comprises a plurality of fa ⁇ ade panel elements distributed along the outside of the inner zone and verti- cally oriented perpendicular to the facade of the building.
  • 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 .
  • a modular building comprising a plurality of vertical frame columns and a plurality of volume modules prefabricated of sheet metal profiles and having a rec- tangular horizontal section, which are supported by the columns on two or more floor levels.
  • the building according to the invention is characterised in that the volume modules are also prefabricated with two frame edge beams which are stronger than said sheet metal profiles and which are horizontally extended along a respective upper end wall edge of the volume module and which are on the one hand linearly connected with front edge beams of adjoining modules on the same floor level and, on the other hand, connected to the columns in such a manner that the horizontal position of the frame edge beams relative to the columns is fixed.
  • a method for manufacturing a modular building comprising the following steps: prefabricating rectangular volume modules of sheet metal profiles, each module also being prefabricated with two frame edge beams which are stronger than the sheet metal profiles and are horizontally extended along a respective upper end wall edge of the module; and mounting at the building site the prefabricated volume modules on two or more floor levels by means of vertical frame columns, frame edge beams of adjoining modules on each floor level being interconnected linearly before the modules of the next floor level are mounted.
  • a module is provided for manufacturing a building as defined above and for use in the method as defined above . Preferred embodiments of the building, the method and the module according to the invention are stated in the dependent claims .
  • modules that are used according to the invention are made up of sheet metal profiles - and thus are to be considered "lightweight modules" - it is preferred for the modules, in per se prior-art manner, to be supported by the columns in such a manner that they are vertically loaded essentially only by their dead weight and payloads.
  • the sheet metal profiles from which the volume modules are made preferably have a material thickness of less than 4 mm, preferably in the range 0.5-3 mm. A preferred embodiment is in the order of 2 mm.
  • the stronger frame edge beams included in the volume modules consist, like the vertical frame columns, preferably of steel beams, such as rolled steel, with a wall thickness which preferably is greater than 4 mm.
  • volume module does not relate to a nor- mally closed volume in the first place, but rather a con- structionally and initially open room or framework of sheet metal profiles without side walls, i.e. a module or cassette defined by geometric surfaces (imaginary walls) , referred to as an open system unit.
  • Each "volume module” included in a building according to the invention can be adjusted entirely to the desired form and function of the building and may especially constitute a room of its own or part of a room with adjoining volume modules on the same floor level.
  • the volume modules can be provid- ed with wall-forming vertical panel elements, a the factory and/or at the building site, according to how the building is divided into rooms.
  • the "prefabricated modules” are prefabricated with at least their sheet metal profiles and their frame edge beams. Prefabrica- tion usually includes also many other elements, such as board material, infill etc, as will be described below.
  • prefabricated is here meant the state of the module when being positioned in the column frame at the building site. Normally, everything can be prefabricated at the factory, but it is also conceivable that certain parts are mounted later, both before and after positioning the modules in the column frame .
  • An advantage of the invention is that it makes it possible to stabilise an open, column-supported lightweight structure for taking up the complex of forces that arise in a building. High material efficiency can be achieved by using lightweight construction engineering.
  • the invention especially makes it possible to manufacture a modular lightweight building from prefabricated volume modules, here called lightweight modules.
  • prefabricated volume modules here called lightweight modules.
  • Use of industrially prefabricated lightweight modules has in itself several advantages related to precision, quality, cost and efficiency, such as a small number of mounting operations at the building site and, thus, a short build- ing time.
  • a special advantage of the invention is that it makes it possible - by means of the stronger frame edge beams at the upper end wall edges of the modules - to partly integrate the frame stabilisation into the light- weight modules. This can be expressed in such a manner that parts of the frame stabilisation which in prior-art systems are provided with a heavy, separate skeleton or frame construction according to the invention are instead integrated into the actual modules.
  • the frame stabilisation partly into the modules, the advantage is obtained that the structure of the modules is reinforced and will have the required stability in spite of its light construction.
  • additional components may also be included in the modules for additional integration of the frame stabilisation into the modules .
  • An advantage of the invention is that the modular building can be manufactured in such a manner that joints positioned adjacent to the columns need not take up moments for frame stabilisation.
  • the joints are essentially intended merely for horizontal and vertical transfer of forces whereas wind forces acting on the building can instead be taken up by frame-stabilising surfaces formed as panels and/or framework.
  • the invention makes it possible to achieve the above advantages while at the same time the joints positioned adjacent to the frame columns are designed in such a manner that the lightweight modules in the fagade of the building can be extended horizontally past the joints.
  • frame stabilisation integrated into the modules includes not only the above-mention- ed frame edge beams, but also what will below be referred to as “frame-stabilising surfaces".
  • frame- stabilising surface should here be understood as a surface in the geometric sense and can be implemented with panel elements and/or with framework. Frame-stabilising surfaces included in the volume modules and the building act to take up horizontal shear forces. This adds to the fact that the joints between the frame edge beams and the frame columns need not take up moments, which in turn makes construction and erection less expensive and easier.
  • each module is prefabricated with a roof panel element fixed to the frame edge beams of the module and/or to the upper longitudinal sheet metal profiles of the module.
  • roof panel elements may be connected horizontally so as to jointly form a larger frame-stabilising horizontal surface.
  • frame-stabilising surfaces can in turn be combined in a suitable manner with special stabilising wall elements and/or staircases, for instance made of steel or concrete in the traditional manner.

  • the volume modules are positioned by means of a crane.
  • the volume modules can be customised according to requirements and be provided with the necessary components. Since the entire inner mounting of infill and installa- tion components can also take place at the factory, high- technological and accuracy-requiring operations can take place within the controllable environment of the factory. They can thus be equipped as sanitary modules, dwelling modules etc.
  • the wall faces of the module i.e. its two long sides 4 and its two short sides or end walls 6, can be opened so that a completed room is made up of one or more modules 2, depending on where wall elements are mounted on the volume modules.

  • the volume module 2 is according to the invention made of sheet metal profiles (beams/girders/bars/panel elements/trapezoidal metal sheets) .
  • the sheet metal pro- file elements preferably have a material thickness of 1-4 mm, preferably less than 3 mm and most preferred less than or equal to 2 mm.
  • the module 2 comprises the following sheet metal profiles : - two top beams (roof edge profiles) 18 and two bottom beams (bottom edge profiles) 20 which form the longitudinal edges of the roof plane 8 and the floor plane 10;
  • roof bars 22 and floor bars 24 which are extended between and connected with the top beams 18 and the bottom beams 20, respectively;

  • Wall boards 12 such as gypsum boards, fibreboards and particle boards, are mounted on the vertical bars
  • the volume module 2 is prefabricated with two frame edge beams 50 which are stronger than the sheet metal profiles.
  • the frame edge beams 50 have several purposes for force transfer, as will be described in more detail below. They are used to transfer forces to adjoining frame edge beams, adjoining frame columns, adjoining modules, adjoining frame-stabilising surfaces and special frame-stabilising systems.
  • a special purpose of the frame edge beam 50 is to form tie beams and compressed beams in connected modules on each floor level .

  • the frame edge beams 50 and the two top beams 18 are located in a common horizontal plane coinciding with the roof plane 8. This is advantageous both with regard to horizontal force transfer between these components and with regard to the possibility of extending the room volume of the module 2 in the longitudinal direction of the modules past the frame edge beams 50.
  • the top beams 18 formed as C profiles are at their ends provided with vertical openings, which preferably match the outer dimensions of the frame edge beams 50.
  • the frame edge beams 50 extend through these openings and have on the outsides of the top beams 18 free beam ends 52 formed with mounting holes 53 for a coupling device that will be described below.

  • the tension rods 54 are fixed by means of plates 58 and nuts 60.
  • the tension rods 54 serve to transfer horizontal forces between the frame edge beams 50 and the top beams 18 in the longitudinal direction of the latter.

This is contrary to the single module system where the horizontal stability is achieved through the board effect in the vertical (gypsum board) walls 12.
  • force arrows indicate schematically how a horizontal (distributed) wind load F coming sideways is taken up in the floor boards 14, 15 and is transferred to the mutually linearly interconnected frame edge beams 50 on each floor level as tensile forces Fl and compressive forces F2, respectively, which are transferred horizontally to the end wall elements 90/92 which transfer the force F3 down to the foundation 80.
  • the interconnected frame edge beams also act to keep the building together.
  • the invention which has been illustrated above by way of an example, creates a technical solution for stabilisation an open lightweight building structure, formed as column-supported systems of joists, and can be imple- mented so that the modules can be prefabricated industrially in a system which requires a small number of mounting operations at the building site.
  • the complex of forces that arise in a building that is subjected to wind forces and inclined forces can by means of the invention be taken up in joints to be transferred by board effect to stabilising units.
  • this can be realised with cooperating frame beams, boards, struts and screw joints, which can all be integrated into the prefabricated lightweight modules and which at the building site are connected to an outer frame by means of joints at the top and bottom of the column portions.
