    15 20 25 30 35 2 each other, but instead seek a solution where both the above-mentioned problem of anchoring the ceiling and the problem of vibration and step sound transmission are overcome.
    A further object of this invention is therefore to provide a device for suspending ceilings on a floor structure in a multi-storey building in a sound-insulating and vibration-insulating manner. This object is achieved with the embodiments of the invention having the features set forth in claims 6-13.
    To facilitate the construction of multi-storey buildings constructed mainly of wood, many so-called prefabricated building elements are manufactured and prefabricated in factories. These must then be transported to the place where the building is erected. As final assembly on site can be very labor-intensive and time-consuming, efforts are made to make the work more efficient by building the prefabricated elements as completely as possible.
    A further object of this invention is therefore to provide a prefabricated floor cassette which is safe to transport and easy to use in the construction of large continuous floor surfaces and ceiling surfaces. This object is achieved with a prefabricated floor cassette having the features found in the characterizing part of claim 13.
    The invention will be described below on the basis of several embodiments and with reference to the figures. Additional advantages and positive effects of the invention will be further described hereinafter.

    Figs. 6 and 7 show detailed views of different fastening devices for attaching the suspended ceiling bar to the suspended ceiling beam.
    Referring to Fig. 1, there is shown a floor cassette which includes a device for suspending a ceiling member from a floor structure.
    The device for hanging comprises a ceiling element 1 of mainly wood which in two opposite outer edges has parallel solid suspended ceiling beams 3 in wood and a frame 4 of wooden lath joists which extend between the suspended ceiling beams 3 and which are orthogonally attached to W: Other_Casedocuments Patent P408- P40803063EN00 besk O90305.doc 10 15 20 25 30 35 3 underside of the suspended ceiling beams. The regulations 4 form the basis for a first board-shaped plate 5, usually made of plaster or some similar flat building board. The plate-shaped plate is attached to the underside of the regulations, which faces away from the suspended ceiling beams. The underside of the first plate-shaped plate 5, which faces away from the suspended ceiling beams, forms the basis for a second plate-shaped plate 18 which is mounted in place, screwed on, after the floor cassette has been installed at the intended place in the building.
    Between the two parallel suspended ceiling beams 3 extends the suspended ceiling bar 8 which at each end is fastened with a fastening device 23 in a respective orthogonally a suspended ceiling beam. Usually the suspended ceiling rule is about 4 meters but can also be longer.
    The fastening device 23 is arranged on the vertical side 3a of the suspended ceiling beam, as shown in figure 1. This figure shows the fastening device 23 comprising a fastening member 25, for example an angular fitting and a mounting joint 24 such as screw joints or nail joints. The angle bracket can be fastened with the mounting joint 24 on the side of the suspended beam as shown in figure 1, but can also be fastened on the upper or lower side of the suspended beam as shown in figure 6. Another simpler embodiment of the fastening device 23 comprises only a screw joint 24 screwed through the suspended beam directly to the suspended beam end , see Figure 7.
    The floor cassette in Figures 1 and 2 also comprises a floor construction 2 which comprises solid, usually wooden-shaped floor beams 6 of standard dimensions.
    Each floor beam 6 comprises a floor beam flange 22 of wood which is arranged orthogonally on the end of the floor beam which is closest to the ceiling element.
    The floor beams rest on load-bearing wall structures in the multi-storey building and form the basis for flooring and also form a framework for insulation material, for example mineral wool, which is inserted in the spaces between the floor beams. The floor beams are placed regularly in the floor cassette and the dimensions and mutual distances of the beams are adapted so that the floor construction shall comply with prevailing building standards. A normal distance between the beams is 40 cm.
    Referring to Figure 1, the device according to the invention comprises a suspension member 7 which is fastened with fastening joints 14 to the underside of the floor beam flange 22. The suspension member 7 encloses the suspended ceiling bar 8.
    The suspended ceiling rule rests in, is supported by, the suspension member and thus the ceiling element is supported by the suspension member. Usually, two suspension members 7, each attached to a respective floor beam flange 22, are arranged to enclose a suspended ceiling bar 8, which is shown, for example, in Figure 1. Thus, the weight of the ceiling element is distributed over several floor joists.
    The suspension member 7 has such a cross-sectional shape that the suspended ceiling bar 8 is enclosed and form-locked by the suspension member. The suspension means prevents W: Other_Casedocuments Patent P408- P40803063SE00 besk 090305.doc 10 15 20 25 30 35 4 thereby rotation of the suspended ceiling bar around the longitudinal axis of the bar. The suspended ceiling bolt and the suspension member have substantially corresponding cross-sections against each other. A suspended ceiling rule with a rectangular or square cross-section is enclosed by a suspension member with a substantially corresponding cross-sectional shape, such as rectangular, square, U-shaped or parts of such cross-sections so that the above-mentioned locking effect is obtained. Figure 3 shows a first embodiment of the device according to the invention which comprises a suspension means 7 which are intended to enclose a suspended ceiling bar 8.
    Figures 4 and 5 show a second embodiment of the device according to the invention which 8 and a suspended ceiling rule and comprises a suspension member 7 enclosing the inside of the suspension member 9,10. The damping element is described in more detail later. a suspended ceiling rule damping element inserted in a gap between the embodiments of the device according to the invention shown in Figures 3, 4 and 5, the suspension member 7 is shown which comprises a stirrup or loop, with a substantially U-shaped cross section having two substantially parallel sides 11 and a bottom part 12 connecting the sides at their respective one end, the bottom part is arranged in a plane substantially orthogonal to the sides, and each side 11 has at its free end a flange 13 which is orthogonally directed outwards from the side. The flange 13 can alternatively also be directed inwards towards the opposite side 11 (not shown in the figure). The flanges 13 are designed to abut and be attached to a floor beam flange 22 with fastening joints 14, preferably screws or the like. The suspension member 7 comprises an inside facing the suspended ceiling bar. The inside has a first inside wall 19a, a second inside wall 19b and a lower inside bottom 20, see figure 3.
    Usually the suspension means is formed in thin sheet metal, preferably perforated thin sheet metal, which is processed, bent, to the shape described above.
    In order to prevent, as far as possible, the transmission of vibrations, frame noise and step noise between the floor joist construction and the ceiling element, vibration-damping and / or sound-absorbing elements of elastomeric and / or viscoelastic materials have been arranged between them. Among the large number of elastomeric materials on the market with damping properties, the damping material marketed under the brand name SYLOMER®, a building purpose, not least due to its high age resistance, resilience properties of elastic rubber material, has proven to be particularly suitable for and vibration damping ability. The viscoelastic step sound insulating material marketed under the brand name STEPISOL®, a flexible urethane foam (polyether foam), has also shown very advantageous sound-absorbing properties in terms of construction, the material can withstand large loads without significant deformation.
    Referring to Figures 4 and 5, the second embodiment of the device according to the invention comprises a damping element 9,10. The damping element comprises one or more plate-like plates which are inserted in different positions between the floor joist and the ceiling element to provide the intended vibration damping and / or sound damping the effect.
    In accordance with the embodiment shown in Figure 4, the damping element 9,10 is placed between the suspended ceiling bar 8 and the suspension member 7. In another embodiment (not shown in the figure), the damping element 9,10 is placed between the suspended ceiling bar 8 and the floor beam flange 22.
    In yet another embodiment (not shown in fi gur) the damping element 9,10 is placed between the flanges 13 of the suspension member and the floor beam flange 22. Various combinations of these embodiments are also conceivable for obtaining a vibration damping and / or sound damping effect. To facilitate assembly, the damping element can be attached to one of the surfaces to which the element is to abut with adhesive joints, for example hot-melt adhesive or the like.
    The second embodiment of the device according to the invention shown in Figure 4 has a vibration damping or sound damping properties. The inner walls of the suspension means damping elements 9,10 comprising several different sub-elements with 19a, 19b are completely or partially covered with a disc damping element 9 with preferably sound-absorbing properties such as STEPISOL® and the inner bottom 20 of the suspension means is completely or partially covered with a plate damping element 10 with preferably vibration damping properties such as SYLOMER®. The suspended ceiling rule in the ceiling element thus does not abut immediately or tightly against the suspension member which is attached to the floor beam flange, but the suspended ceiling rule rests resiliently on the damping element in the suspension member.
    Figure 2 shows the floor cassette with transport fuses in the form of spacer blocks 21. A spacer block 21 is attached to the frame 4 in the ceiling element 1 and floor beam flange 22 in the floor construction in the final floor cassette. Before transporting the finished one placed in a position corresponding to a floor cassette from the factory to the end user site, a screw connection is arranged through the ceiling element, the spacer block and the floor beam flange which is arranged directly above the screw connection. thus applying a cohesive force in a safe and trouble-free manner to the end-user site. When the floor cassette is finally installed in the new multi-storey building, the screw connection that fixed the ceiling element to the floor beams is removed and the ceiling element is lowered by its own weight to be subsequently supported by the suspension device. Usually the ceiling element is displaced about 1-2 cm downwards in the vertical direction. In a floor cassette provided with the suspension device according to the invention comprising damping elements as previously described, this ceiling element results in immediate contact with displacement in that it is then not in the floor beams and the floor beam flanges without the suspension beam flanges. thus, vibrations or sounds are not transmitted.
    The present invention is not to be construed as limited to what is described above and what is shown in the figures, but may be modified and modified in a variety of ways within the scope of the inventive concept set forth in the appended claims.
