    Each end of said side beam comprises coupling means 28, 30 arranged toreleasably engage the corresponding connecting units 20, 22 of the struts 14, 18.
    Each of the coupling means preferably comprises a wedge head unit having onecolumn and a wedge 32, 34.
    The body 10 further comprises a platform 36, 38 arranged at least partiallysupported by the side beam 24. In the embodiment shown in Fig. 1, the frame comprises twoplatforms 36, 38 each of which forms part of the floor of the frame 10. This is onepreferred design of the platform 36, 38, namely that it forms a floor portion ofthe frame 10. Thus, each of the platforms 36, 38 in Fig. 1 could alsocalled floor panel. A platform 36, 38 to the body 10 preferably has oneessentially two-dimensional extent, i.e. a limited thickness and significantlygreater length and width. As an example it can be mentioned that each of the length andthe width of a platform 36, 38 is preferably at least more than 5, preferably more than10 times the thickness of the platform 36, 38.
    Fig. 2 is an exploded view of a portion of the body 10 of Fig. 1. As shown in Fig. 2,the portion comprises four side beams 24, 25, 40, 41. Furthermore, the portion comprises a pluralitytransverse reinforcing beams 42 and corner elements 44, 46 for couplingthe sidebars.
    Fig. 3 shows a cross section of a portion of a body 10 according to the present invention. 1 FIG.3 illustrates the cross section of the side beam 24 and a cross section of a portion of the platform 36.
    The platform 36 comprises a panel 46 which may, for example, be made of onewood materials, such as plyfa (trade name plywood) or other composite that includeswood. Only as an example can it be mentioned that the panel can be a wood fiber board, such as oneOSB board. Alternatively, or in addition, the panel may comprise a sandwich material which inin turn comprises one or more components in metal and / or plastic.101520253035PG18233SEOOFurthermore, Fig. 3 illustrates a cross section of a support member 48 arranged to be connected toplatform 36. In the embodiment shown in Fig. 3, the support member 48 is fixedly connected tothe platform 36 in that the support member 48 is fixedly connected to the panel 46 by means of aadhesive bandage (not shown). Other designs of the dressing may also be suitable, such asscrew joints, nail joints and / or weld joints. In further embodiments of the frame10, the support member 48 may be fixedly connected to the panel 46 via one or moreintermediate means (not shown in Fig. 3).
    The support means 48 comprises a support surface 50 arranged to abut against a loading surface 52 ofthe side beam 24. In the design of the side beam 24 shown in Fig. 3, the load surface 52 isessentially flat. Furthermore, the load surface 52 extends substantially in a horizontal plane thenthe side beam is mounted in the frame 10. The support surface 50 in Fig. 3 is substantially flat and formsbottom of a hollow profile 54 which in turn forms an integral part of the support member 48.
    Furthermore, it can be seen from Fig. 3 that the support member 48 comprises a stop strip 56 forprevent displacement of the platform 36 in at least a first lateral direction S1 thenthe side beam 24 and the platform 36 are mounted in the frame 10. The first side direction S1is substantially perpendicular to the longitudinal direction L of the side beam as well as the vertical directionV. The stop strip 56 extends below the support surface 50 when the platform 36 is mounted inframe 10. In other words, the list of appropriations has a lowest point belowthe lowest point of the support surface 50.
    As can be seen from Fig. 3, the locking in the first side direction S1 is effected throughthat an abutment surface 58 of the stop strip 56 is arranged to abut against a surface 60 ofside beam 24. It should also be noted that the platform 36 is preferably prevented from adisplacement in a second lateral direction opposite to the first lateral direction S1 bythe side beam on the opposite side (not shown in Fig. 3) and the portion of the platform 36 which isarranged to engage with opposite side beams are provided with a correspondinglateral displacement reading device (not shown in Fig. 3).
    Fig. 3 further shows that the support member 48 comprises a support member extruder profile and ithe design of the support member 48 shown in Fig. 3 is in fact the whole of onesupport member extruded profile. Preferably, a support member extruder profile is madeof a light metal or a light metal alloy, for example aluminum or aaluminum alloy.1015202530PG18233SEO0Furthermore, it can be seen from Fig. 3 that the stop strip 56 preferably has a hollow cross-section andthat this forms part of the above-mentioned support member extruder profile. Preferably havethe stop strip 56 a length, i.e. an extension in the longitudinal direction L of the side beam, whichis at least 40%, preferably at least 60%, more preferably at least 80%, ofthe length of the side beam 24 so as to evenly distribute any loads being transferredbetween the support member 48 and the side beam 24. In addition, a stop strip 56 having a length iany of the above ranges is advantageous because it can facilitate alignment ofthe support member 48 with the side beam 24.
    The support member 48 shown in Fig. 3 further comprises a further hollow profile 62 whichis located above the two other hollow profiles 54, 56. The support member 48 in Fig. 3 hasfurthermore a panel load surface 64 arranged to support a portion of the panel 46 and apanel stop surface 66 arranged to prevent displacement of the panel 46 in at least the firstlateral direction S1.
    Furthermore, it is understood from Fig. 3 that in the design of the support member 48 shown thereinthe stop strip 56 as well as at least a main portion of the platform 36 on the same sideabout the side beam 24 when the platform 36 is mounted in said frame 10. Preferably, andAs shown in Fig. 3, the entire support member 48 is located on one side of the side beam 24centerline CL. More preferably, the entire platform 36 is also on the same sideabove center line CL. This design meant that an additional platform (notshown in Fig. 3) can be easily connected to the support beam 24, namely from the left side in Fig. 3.
    The design of the support member 48 and the side beam 24 shown in Fig. 3 has the advantage thatthe risk of getting stuck when assembling these parts is relatively low, as the fitter does notneed to have their hands in the vicinity of the loading surface 52 or the support surface 50 but can insteadgripping the platform 36 at the panel stop surface 66.
    The support member 48 in Fig. 3 further comprises a first locking groove 68 which in the design ofthe support member 48 shown in Fig. 3 is located above the stop strip 56 and which firstlocking groove 68 is also T-shaped. The first locking groove 68 years arranged tocooperating with a second locking groove 70 which is located on the side beam 24, thisThe interaction takes place by connecting a locking member (not shown) between the first 68 and the second101520253035PG18233SE0070 the locking groove so as to prevent the platform 36 from moving in a vertical directionrelative to the sidebar 24.
    The side beam 24 also has a third locking groove 72 and both the second 70 and the third72 the locking groove is located below an upper portion 74 of the side beam 24, which is the uppermostportion 74 in the design of Fig. 3 has a substantially rectangular cross-section, where the loading surface52 forms the uppermost surface of the rectangular cross-section when the side beam 24 is mounted inthe frame 10. It is further understood from Fig. 3 that a vertically extending side wall 60 thereofthe rectangular cross-section constitutes the surface against which the abutment surface 58 of the stop strip 56is arranged to lie on.
    In addition, the design of the side beam 24 shown in Fig. 3 includes a lower portion 76with a hollow cross-section. Preferably, the lower portion 76 has a bottom surface 77 with aindentation upwardly, preferably toward the center 78 of said lower portion 76, preferablythe lower surface 77 is arched upwards, even more preferably towards the center 78 of the lower portion 76.
    The advantage of the above-mentioned design of the lower surface is that a fastening means, such asa rivet 80, and then in particular the rivet head 82, which is used to attach a portion of onecoupling means, such as a previously discussed wedge head unit (not shown in Fig. 3), willbe relatively protected from external stresses, for example during transport and installation ofbody 10. Preferably, the indentation has a depth greater than that of the rivet head 82height.
    As previously discussed in connection with the support means, the side beam 24 comprises aside beam extruded profile and in the design shown in Fig. 3 is actually the side beam24 of the side beam extruder profile. The side beam extruder profile is preferablymade of a light metal or light metal alloy, such as aluminum or aaluminum alloy.
    Fig. 4 illustrates an alternative design of the support member 48. The support member 48 in Fig. 4 isloosely connected to the platform 36 and has a substantially H-shaped cross-section with ahorizontally extending portion 84 and two vertically extending portions 86, 88.
    The support member 48 in Fig. 4 has two stop strips 56, 57, one on each side of the side beam 24.
    These abutment strips 56, 57 are formed by the lower portions of the respective vertical onesextending portions 86, 88.1015202530PG18233SEOO10In the design shown in Fig. 4, the platform 36 also has a load carrier part 94 which isfixedly connected to the panel 46 of the platform 36. The load carrier part 94 is arranged toat least partially located between the upper portions 90, 92 of the respective vertical onesextending portions 86, 88.
    The support member 48 in Fig. 4 preferably consists of extruded light metal, such asaluminum. The support member 48 shown in Fig. 4 preferably has a length which isat least 40%, preferably at least 60%, more preferably at least 80%, of the lengthin the sidebar 24.
    The support member 48 in Fig. 4 may be made of a material other than the material whichthe side beam 24 is made of. For example, the support member 48 may be made of steel orplastic. If the support member 48 is made of plastic, it may have a damping function in contactbetween the platform 36 and the side beam 24.
    However, it is also possible to provide a side beam 24 with a plurality of shorter support members 48, whichfor example, is shorter than 10% of the length of the side beam 24, which is distributed along the side beamlength. In other words, such a body 10 comprises a plurality of support members 48 which wereand one is arranged to be placed between the side beam 24 and the platform. These smallersupport means 48 may be made of plastic for example. An advantage with many smallsupport means 48 in plastic is that each of these support means is relatively inexpensive and easy to havewith itself. Thus, if one of these support members 48 were to break at e.g.assembly or transport, this can be easily replaced without any major cost.
    Several embodiments of the present invention are possible within the scope of the inventionaccompanying claims. For example, it should be pointed out that embodiments of the frame cancomprise a platform connected to four or more side beams where each connectionhas a stop strip to prevent lateral displacement.
