Definitions

  • the invention relates generally to the field of modular buildings. More specifically, the inventive concept relates to modular buildings of the type built of a plurality of prefabricated volume modules, preferably light-weight modules made of sheet-metal sections. The invention also relates to a method of manufacturing such a building and also a prefabricated module for this purpose.
  • the invention makes it possible to manufacture such modular buildings using so-called light-weight construction engineering (in contrast to traditional building constructions) and industrially prefabricated light-weight 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 columns and horizontal bars and beams which are joined to each other in a torsionally rigid manner in joints of the frame construction.
  • Both horizontal forces (wind forces) and vertical forces (payloads and dead weights) are transferred to the frame construction.
  • torsionally rigid joints cause a great technical problem, in particular to solve all the rigidity requirements that are placed on a modular building, especially torsionally rigid joints where different materials, forces and functions meet.
  • SE 9404111-8 discloses a modular multistorey building which, with respect to force take-up, is divided into (i) an inner zone, which takes up vertical forces and comprises 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 (ii) a façade zone, which is arranged immediately outside the inner zone and takes up lateral forces for lateral stabilisation of the inner zone and hence the entire building.
  • the façade zone comprises a plurality of façade panel elements which are distributed along the outside of the inner zone and vertically oriented perpendicular to the façade of the building. In this solution, use is thus not made of horizontal beams as included in prior-art frame constructions.
  • the payloads and dead weights of the modules are distributed over and taken up by the columns in the inner zone while most of the horizontal wind forces acting on the building are taken up by the façade panel elements arranged perpendicular to the façade in the façade zone outside the inner zone.
  • a drawback of this prior-art technique is that the necessary size and cost of the horizontally stabilising façade zone quickly increase as the number of floor levels in the building increases.
  • the solution involving a special façade zone is not quite satisfactory.
  • WO 03/093593 discloses a modular building which like the building according to SE 9404111-8 has a plurality of vertical module-supporting columns.
  • Volume modules made of sheet-metal sections are supported by the columns in two or more floor levels.
  • the volume modules are prefabricated with two frame edge beams which are stronger than said sheet-metal sections and which are each horizontally extended along an upper end wall edge of the volume module.
  • the frame edge beams are mounted in upper roof beams and arranged in the same plane as these.
  • the frame edge beams are on the one hand linearly connected to frame edge beams of adjoining modules on the same floor level and, on the other hand, connected to the columns so that the horizontal position of the frame edge beams relative to the columns is fixed.
  • the columns for the first floor level are mounted. After that the prefabricated volume modules on the first floor level are mounted by the means of already mounted frame columns, the frame edge beams of adjoining modules on the first floor level being linearly connected to each other. Then the process is repeated by mounting the columns for the next floor level and, after that, mounting on these the modules of the second floor level.
  • the modules are supported by the columns so that they are vertically loaded essentially only by their dead weight and payloads.
  • the stronger frame edge beams included in the volume modules like the vertical frame columns separate from the modules, consist of steel girders, such as rolled steel.
  • An object is to provide an alternative modular building system of the type stated by way of introduction.
  • a special object is to provide a modular building which is quick, inexpensive and effective to manufacture and mount and which requires a reduced number of operations at the building site and a reduced number of components for mounting.
  • a modular multistorey building comprising a plurality of prefabricated modules, which each form a module volume and which are arranged in at least an upper and a lower floor level with a horizontal module distance between adjoining module volumes in each floor level, said building being characterised in that the modules are interconnected by a plurality of connecting devices, which each cooperate with four modules, consisting of two modules in the lower floor level and two modules in the upper floor level, each module is prefabricated with a plurality of vertical sectional elements, which each have a length exceeding the height of the module volume, for each connecting device, two upper vertical sectional elements, each belonging to one of the two upper modules stand via the connecting device on two lower vertical sectional elements each belonging to one of the two lower modules, and each connecting device is provided with positioning elements, which cooperate with the two upper and the two lower vertical sectional elements to position them relative to each other in the horizontal plane.
  • the modules included in the building are preferably prefabricated as "light-weight modules" of sheet-metal sections.
  • module does not relate in the first place to a normally closed volume, but rather a constructionally and initially open room or framework of sectional elements without side walls.
  • the volume of the module (“module volume”) can be considered to be defined by geometric surfaces (imaginary walls).
  • Each module can be adjusted completely to the desired building shape and function and can especially constitute a room or part of a room together with adjoining modules in the same floor level.
  • the modules can be provided with wall-forming vertical panel elements, at the factory and/or at the building site, depending on the planning of the rooms.
  • prefabricated modules are prefabricated with at least their vertical sectional elements and top and bottom constructions joined by the same.
  • the prefabrication includes preferably, but not necessarily, also many other elements, such as panel material, infill, etc.
  • prefabricated is meant the state of the module when being positioned at the building site. Normally as many components as possible can be prefabricated at the factory, but it is also conceivable that certain parts are mounted later, both before and after positioning of the modules.
  • Each connecting device can be designed in many ways within the scope of the inventive concept.
  • Each connecting device can be formed as an integral unit or be made of several parts which are assembled at the building site in connection with the mounting of the modules.
  • at least some of the positioning elements of the connecting devices may consist of separate parts which are mounted at the building site.
  • each connecting device of a lower part which interconnects the lower modules and an upper part which interconnects the upper modules, the upper and the lower part being interconnected horizontally in a suitable manner, for instance using a female-male configuration.
  • An advantage of the multistorey building according to the inventive concept is that it can be manufactured without using separate strong columns since vertical forces appearing in the building can be taken up directly by the vertical sectional elements of the modules.
  • a further advantage of the building according to the inventive concept is that the prefabricated modules can be interconnected at the building site with few mounting operations and with few components.
  • a special advantage of the building according to the inventive concept is that interconnection of the modules can be carried out with a plastic cover or the like still on the modules, thereby preventing undesirable rain leakage into the interconnected modules or at least significantly reducing such leakage.
  • the vertical sectional elements of the modules have several functions:
  • the modules may comprise, in addition to the above-mentioned vertical sectional elements, additional vertical elements, such as sections and/or panel elements, which do not satisfy all the above-mentioned functions.
  • the vertical sectional elements included in the modules may consist of, for instance, U sections, square sections or tubes.
  • the vertical sectional elements are sheet-metal sections, most preferred sheet-metal sections of high-strength steel.
  • the thickness can be 1-4 mm, preferably less than 3 mm, and most preferred in the range 2.5-2.0 mm.
  • the connecting devices have several functions and can be considered multifunctional devices:
  • the construction can be implemented so that the connecting devices are effectively held in place due to the vertical load exerted on them by superposed modules standing on the connecting devices.
  • the number of mounting steps at the building site can be reduced.
  • the connecting concept according to the invention makes it possible to provide a construction in which the connecting devices constitute the only "loose" construction elements to form the joints.
  • the vertical sectional elements taking up vertical forces are included in the prefabricated modules and all connecting functions in the joints can be implemented with the connecting devices. Additional elements can also be mounted at the building site, especially panel elements (such as trapezoidal plates) over horizontal neutral zones between the modules.
  • the "passive" and “active” positioning functions of the connecting devices as described above comprise preferably at least passive positioning in all directions in the horizontal plane.
  • the positioning may concern only limited horizontal positioning, for instance positioning which ensures that a horizontal minimum distance is maintained between adjoining modules.
  • the positioning elements of the connecting devices can preferably be formed with guiding surfaces, such as wedges, pyramids, cones, angled plates or the like.
  • Each connecting device can be formed as a completed unit comprising the positioning elements, in which case the connecting device is first mounted on two lower modules to connect and position them relative to each other, after which two upper modules are mounted on the connecting device.
  • each connecting device can be made of several parts.
  • a connecting device can be formed on the one hand of a horizontal distance element, which rests on the vertical sectional elements of the lower modules and supports the vertical sectional elements of the upper modules and, on the other hand, a number of separate positioning elements which are mounted on the horizontal distance element afterwards, that is at the building site during the assembly of the modules.
  • the positioning elements of the connecting devices cooperate with the vertical sectional elements of the modules by at least some of the positioning elements being inserted into the ends of the vertical sectional elements. This results in a "smooth" construction by the positioning elements being concealed in the completed connection while at the same time the actual mounting will be simple since all connection can take place with vertical mounting.
  • each connecting device comprises at least two upper and two lower positioning elements, which are each inserted into one of the two upper and two lower vertical sectional elements, respectively.
  • a plurality of positioning elements can be used to position each vertical sectional element and, as will be described below, one and the same positioning elements can cooperate with both upper and lower vertical sectional elements.
  • each connecting device comprises a horizontally extended, plate-shaped element, which forms a horizontal spacer to maintain said horizontal module distance between the module volumes and which has an upper side supporting the two upper vertical sectional elements and an underside which is supported by the two lower vertical sectional elements.
  • the vertical sectional elements may comprise at least four vertical corner sections arranged along the vertical corner edges of the module.
  • the vertical sectional elements may also comprise vertical central sections arranged centrally on two opposite sides of the module, whereby two adjoining modules can thus be interconnected at their corners as well as between the corners.
  • each module has, in addition to its four vertical corner sections, four vertical central sections arranged in pairs centrally on two opposite long sides of the module, the central sections in each pair having a mutual horizontal distance corresponding to said horizontal module distance.
  • each module is further prefabricated with a plurality of upper horizontal sectional elements, here referred to as connecting sections, which are positioned above the geometric top plane of the module volume, and each connecting device engages two such connecting sections, each belonging to one of two adjoining modules, to transfer horizontal forces in the building in the longitudinal direction of the connecting sections.
  • the connecting sections interconnected by the connecting devices serve to form, in each floor level, combined "traction and compression beams" in interconnected modules to transfer horizontal forces between the connecting sections in the longitudinal direction of the same.
  • the engagement between the connecting devices and the connecting sections may comprise screw joints, such as self-tapping screws, and/or the engagement can be formed by extensions of the connecting device having downwardly projecting engaging portions and the upper horizontal sectional elements of the lower modules being formed with recesses or the like, in which the downwardly projecting portions are inserted and engage.
  • the engaging portions can consist of, for instance, a plurality of punched bulges and depressions. Particularly the system can be made without using bolts and rivets.
  • the engagement between the connecting devices and the connecting sections of the modules is performed by the positioning elements of the connecting devices, which positioning elements will have a double function: (i) horizontal positioning of the vertical sectional elements and (ii) transfer of horizontal traction and compressive forces between the connecting sections.
  • the four vertical sectional elements and the two upper connecting sections, with which a given connecting device cooperates form a common geometric vertical plane.
  • the upper connecting sections of the modules have end portions which extend inwards over the upper ends of the vertical sectional elements.
  • each connecting device will rest on two vertical sectional elements via two such end portions.
  • This embodiment also allows that at least some of the positioning elements of the connecting devices are adapted to provide, while at the same time performing the horizontal positioning of the vertical sectional elements of adjoining modules, also said engagement between the connecting devices and the connecting sections for transferring horizontal forces in the building.
  • Fig. 1 illustrates a volume module generally designated 10.
  • the construction, function and manufacture of the module 10 can largely be performed in accordance with that described in the above-mentioned WO 03/093593, as will be described below.
  • the module 10 differs from prior art mainly in respect of the parts of the module which cooperate with or are included in the joints of the building and which take part in the transfer of vertical forces and horizontal forces.
  • the module 10 is prefabricated preferably at a place other than the building site, thereby allowing the use of the advantages of the factory as regards rational handling of materials, quality and efficiency.
  • the modules are put in place by a crane.
  • the modules can be customised at the factory and be provided with the necessary components. Since the entire inner mounting of infill and installation components can also take place at the factory, high-technological and accuracy-demanding operations can take place within the controllable environment of the factory. They can thus be equipped as sanitary modules, residential modules etc.
  • the faces of the modules 10, that is the two long sides and the two short sides or end walls, can be opened so that a completed room can be built from one or more modules 10, depending on where wall elements are mounted on the modules.
  • Such wall elements can be mounted at the factory and/or mounted at the building site.
  • the module 10 has a rectangular horizontal cross-section according to Fig. 1.
  • the volume of each module has the dimensions 3.6 m * 7.8 m. This does not include what is referred to below as "neutral zones" between the volumes of the modules 10 (see designation NZ in the Figures).
  • the volume of the module 10 is defined by the following geometric planes: the two vertical side planes, the two vertical end wall planes, a horizontal top plane 12 and a horizontal bottom plane 14.
  • the vertical planes can be more or less closed by means of joists and/or panel material.
  • parts of the module extend outside these planes, which define the "volume" of the module.
  • top plane 12 and the bottom plane 14 are normally closed by panel elements 16, of which broken away parts are shown schematically in the form of trapezoidal plate.
  • This trapezoidal plate is used to transfer horizontal forces.
  • panel elements 16 also constitute part of said "sheet-metal sections" of the module and are thus preferably included in the prefabricated module, especially the bottom plate.
  • the module 10 is made of sheet-metal sections (beams/joists/battens/panel elements/trapezoidal plates).
  • the sheet-metal sections preferably have a material thickness of 1-4 mm, preferably less than 3 mm, and most preferred less than 2 mm, or 2 mm.
  • the material is preferably high-strength steel for the vertical sectional elements and connecting sections that will be mentioned below.
  • the module 10 comprises in the shown embodiment the following sheet-metal sections:
  • end wall and side joists can be arranged, as well as sections for mounting of such end wall joists, side joists, insulation etc.
  • wall panels such as plasterboard, fibreboard and particle board, can be mounted on the long sides and end wall sides.
  • the legs of the here U-shaped vertical sectional elements 30, 32 are further provided with inwardly bent edges 33, as illustrated in Fig. 7.
  • the vertical sectional elements can have a different shape, such as a square profile.
  • the floor structure of the superposed modules will thus be positioned at a vertical distance from the ceiling structure of the subjacent modules, thereby preventing them from resting directly on each other.
  • the horizontal connecting sections 34 are aligned with the vertical corner sections 30 and form together with these a "frame" in the form of an inverted U around the geometric top plane 12 of the module volume 10 and its two geometric side planes.
  • the centrally positioned connecting sections 35 and the vertical central sections 32 form two "frames" outside the geometric plane of the module, as illustrated schematically in Figs 1 and 2.
  • the vertical sectional elements 30, 32 are positioned in the neutral zones of the building.
  • the length of the connecting sections 30 and 32 is selected so that each connecting section is fitted between the extensions 36 of two vertical sectional elements.
  • the connecting section 34 has substantially the same height as the extensions 36 of the corner sections (see Figs 5 and 8), so that a connecting element 60, when mounted according to Figs 5-10, vertically abuts against both the extensions 36 of the vertical sectional elements and the upper side of the connecting section 34.
  • the vertical sectional elements 30, 32 also have shorter lower extensions which extend a distance downwards past the geometric bottom plane.
  • Figs 4A and 4B illustrate a first embodiment of a multifunctional connecting device 60 for connecting light-weight modules 10 according to Fig. 1 to form a completed building according to Figs 2 and 3.
  • the connecting device 60 is also made of sheet metal, preferably high-strength steel, and has the shape of a U profile provided with wings 62.
  • the base of the U constitutes a plate-shaped element 64 which forms the tip of the connecting device 60.
  • the plate-shaped element 64 supports on its upper side two upper positioning elements 66, which are positioned at a predetermined horizontal distance from one another, corresponding to the width of the neutral zones NZ of the building. As shown in Fig.
  • two lower positioning elements 68 are arranged on the underside of the plate-shaped element 64, straight below the upper positioning elements 66. While connecting the modules to each other at the building site, the positioning elements 64 and 66 are inserted into open ends of corresponding vertical sectional elements 30, 32 to position them in exact alignment with each other. To this end, the positioning elements 64, 66 are preferably formed with one or more guide surfaces 70, which facilitates the mounting of both the connecting devices 60 and the modules which are to be placed on the connecting devices 60.
  • each positioning element 66, 68 is made of a bent metal sheet which is fixedly connected to the plate-shaped element 64.
  • Other embodiments with more guide surfaces are conceivable, such as cones, pyramids or the like.
  • the connecting device 60 has a central portion 72 positioned between the positioning elements 66, 68 and two opposing extensions 74.
  • the extensions 74 are provided with means which allow the extensions to be brought into engagement with the connecting sections 34 of the modules, as will be described below.
  • these means consist of screw holes 76, for receiving preferably self-tapping screws 80 (see Fig. 9) in connection with mounting.
  • the length of the two extensions 74 of the connecting device 60 is selected with regard to how far the connecting devices 60 are to extend over the connecting sections 34 and how great horizontal forces are to be transferred by the connecting device 60.
  • the extensions 74 are substantially of the same length as the central portion 72.
  • the length of the central portion 72 of the connecting device 60 can be varied, thus making it possible to easily vary the width of the neutral zone NZ.
  • the U profile of the connecting device 60 is preferably dimensioned according to the outer dimensions of the upper connecting sections 34, 35 of the modules 10, so that the connecting device 60 in connection with mounting encloses the connecting section 34, 35 as shown in cross-section in Fig. 8.
  • the connecting device 60 will also have the function of serving as a sideways positioning element, that is guiding of the modules in the lateral direction, perpendicular to the longitudinal direction of the connecting device 60. This is particularly preferred if the modules 10, when being set up, are not fully aligned with each other and possibly have a certain skewness. By applying the connecting devices 60, such skewness can be effectively eliminated.
  • a foundation will be made at the building site, here schematically shown in the form of plinths 90 on the ground 100 (Fig. 3).
  • a first set of connecting elements 60 are then arranged on these plinths.
  • four light-weight modules 10A-10D are to be mounted, two lower modules 10A and 10B and two upper modules 10C and 10D.
  • the marked circle C in Figs 2 and 3 represents a joint between these four modules and corresponds to the construction shown in Figs 5-10.
  • a total of twelve lower connecting elements 60' are used in this embodiment. It will be appreciated that these twelve lowermost connecting elements 60' in the building can have a significantly different appearance from that of the connecting elements 60 which are positioned centrally in the building. Thus, they can basically consist of only the plate-shaped element 64 and the upper positioning elements 66. It will also be appreciated that the connecting elements which are positioned along the sides of the building can possibly be made shorter since they are not used to connect adjoining modules to each other.
  • the two lower modules 10A and 10B are put in place by a crane, the downwardly open ends of the vertical sectional elements 30, 32 of the modules 10A, 10B receiving the upper positioning elements 66 of the already mounted connecting devices 60', whereby the lower modules 10A, 10B are positioned correctly both horizontally and vertically.
  • the lower modules 10A, 10B thus have been positioned, they usually do not have to be secured in the vertical direction, although this is of course possible.
  • a neutral zone NZ exists between horizontally adjoining modules 10, which zone in the completed building can be bridged in a suitable manner in ceiling and/or floor if adjoining modules 10 are to be connected to each other.
  • the connection of the ceiling elements of the modules may effectively help to stabilise the building.
  • the interconnection of the floors of the modules makes it possible to form larger rooms.
  • the connecting devices 60 and the connecting sections 34 can be formed with horizontally cooperating gripping means, such as projecting portions and corresponding depressions/recesses, so that this linear engagement is automatically achieved by the connecting devices 60 being mounted on the lower modules 10A, 10B.
  • gripping means such as projecting portions and corresponding depressions/recesses
  • the modules of the second floor level (here represented by the modules 10C and 10D) can be put in place by a crane, the same guiding principle being used as in the mounting of the lower modules 10A, 10B.
  • the vertical sectional elements 30, 32 of the upper modules 10C, 10D will rest directly on the upper side of the connecting devices 60.
  • This mounting principle can be repeated to reach the desired height of the building, as shown for illustration purposes with a three-storey building in Fig. 3.
  • a special advantage offered by the invention is that the above-described interconnection of the modules can take place with a plastic cover or the like still on the modules, whereby it is possible to eliminate undesirable leakage of rain or at least significantly reducing such leakage.
  • the modules When the modules are delivered from the factory, they are normally covered with plastic or the like. When the modules in the lower floor level are to be mounted, this can be done without necessitating removal of the leakage-protecting plastic cover. When the connecting devices 60 are then to be mounted on the set-up modules, this can also take place without removing the plastic cover.
  • the connecting devices 60 can simply be pressed down in the plastic cover, which then is either torn over a limited area adjacent to the vertical sectional elements, or is kept intact if sufficiently "loosely" mounted on the module. Since no separate columns for take-up of vertical loads are required in the construction, there will be no leakage problems in mounting of such columns for subsequent floor levels either.
  • a further advantage of moment of force not being generated in the joints is that the width of the neutral zone can very easily be varied by changing the central portion 74 of the connecting devices 60, as illustrated by examples in Figs 13A and 13B. Such an increase of the width of the neutral zone does not cause an increasing moment of force to arise in the joints of the building.
  • top plane/ceiling construction 12 of the lower modules 10A, 10B is positioned at a vertical distance from the bottom plane/floor construction 14 of the upper modules 10C, 10D, whereby the modules 10 basically do not exert vertical loads on each other, only via their vertical sectional elements 30, 34.
  • the connecting sections 34, 35, interconnected by the connecting devices 60, of the modules 10 take up horizontal traction and compressive forces originating from, for instance, wind loads on the building.
  • An advantage of the present inventive concept is, however, that the upper connecting sections do not have to be made in the form of strong steel girders and also that the upper connecting sections do not have to be mounted in the longitudinal light-weight sections as described in WO 03/093593, which gives advantages both in prefabrication at the factory and in mounting at the building site.
  • a module 10 according to the embodiment illustrated normally has a floor surface of about 27 m 2 or more, if extended.
  • they can be adjusted to optional plannings of rooms.
  • stabilisation can take place in different ways, reference being made to WO 03/093593 for further details in this respect.
  • This document also describes how modular buildings of the type intended by the present application can be provided with special frame stabilising elements, and also in this respect reference is made to WO 03/093593 for further details and options.
  • Fig. 11 shows eight interconnected rectangular modules 10 1 -10 8 in a floor level.
  • the six modules 10 1 -10 6 are oriented in a first direction with their long sides interconnected, as marked in the circles A and B.
  • the two remaining modules 10 7 -10 8 are mounted perpendicular to the others, the module 10 7 being connected to the two modules 10 5 and 10 6 , as marked in the circles C and D.
  • Figs 12A-D illustrate schematically how the vertical sectional elements 30/32 of the modules are oriented inside the four circles A-D. In the cases A and B, the interconnection conforms with the above-described embodiment.
  • connecting devices 60 according to Figs 4A and 4B cannot be made to intersect directly in the same vertical plane.
  • a specially designed connecting device can have, for instance, the shape of a cross, a T or be formed as a purely plate-shaped element without vertical sides.
  • the inventive concept makes it possible to manufacture modular multistorey buildings with very flexible surface sizes, although the building technique is basically "modular".
  • the rectangular modules 10 can easily be extended beyond the corner sections 30 by extending the top sections 18 and the bottom sections 20.
  • the surface size can easily be varied by adjusting the size of the connecting devices 60, as illustrated in Figs 13A and 13B.
  • Fig. 14 is a schematic exploded view in perspective of an alternative embodiment of a connecting device 160.
  • This embodiment differs from the previous embodiment by the horizontal connecting sections 34 of the modules 10 being extended (at reference numeral 37) inwards over the upper ends of the vertical sectional elements 30 (and preferably also the ends of the vertical central sections 32).
  • the extensions 37 are provided with a plurality of through holes 39 inside the area which corresponds to the cross-section of the vertical sectional elements 30.
  • the connecting device 160 is shorter than the connecting device 60 in Figs 4A and 4B and is provided with a plurality of positioning elements 166 adapted to be received in the holes 39 in order to linearly interconnect the connecting sections 34.
  • the positioning elements 166 here in the form of conical studs, will thus have the three functions of (i) positioning the lower vertical sectional elements in the horizontal plane, (ii) positioning the upper vertical sectional elements in the horizontal plane relative to the lower sectional elements, and (iii) linearly interconnecting the connecting sections 34.
  • the advantage of this embodiment is on the one hand that mounting will be quicker and can be carried out with fewer operations and, on the other hand, that the completed construction will be smoother since no special connecting means, such as the screws 80, will be required outside the vertical sectional elements 30.
  • the embodiments can be combined, for instance by also using screws 80 or the like in the embodiment in Fig. 14.
  • Figs 15A and 15B which are cross-sectional views of the embodiment in Fig. 14, the two upper vertical sectional elements 30 each stand on the upper side of an extension 37 of a connecting section 34.
  • the studs are preferably fixedly mounted, such as welded, in the connecting device 166, which thus is an integral unit during mounting.
  • the connecting device may consist of a plurality of separate parts which will not be joined until in the interconnection of the modules. Two examples of this are illustrated in Figs 16A and B as well as in Figs 17A and B. In these two examples, the positioning elements of each connecting device consist of four yokes 266 and four toothed plates 366, respectively, which in the interconnection of the modules 10 are inserted into corresponding openings in the plate-shaped elements of the connecting device.
  • the connecting device can be U-shaped, as shown in the examples, or only a plate-shaped element. It is also possible to combine these embodiments by using a thicker plate-shaped element which abuts against the lower vertical sectional elements and which is then enclosed by a less thick "hat profile" to stabilise the plate-shaped element, especially in the neutral zone.
