DESCRIPTION OF EMBODIMENTS

[0014] The building construction shown in FIG. 1A comprises a first and a second building element X in the form of a wall block 1, the vibration-damping device 2 as well as a building element in the form of a beam layout 3. The wall blocks 1 are stacked on each other with their end edges against each other, forming a wall 4. In connection with the joint 5 between the wall blocks 1A, 1B, a building element is placed in the form of a beam layout 3.

[0015] In an embodiment, the vibration-damping device 2 according to FIG. 1B is placed on a corbel 6 in the form of a bracket. The one corbel portion 7 is fixedly mounted on the wall block 1, in connection with the bracket 5 between two wall blocks 1A, 1B. The corbel 6 is configured with the one portion 7 directed in parallel with the wall 1 and the other portion 8 directed in parallel with the beam layout 3. The portion 7 that is parallel to the wall 1 is provided with screw holes 9 through which the corbel 6 can be fastened with screws in the wall 1. The portion 8 that is parallel to the beam layout 3 constitutes attachment for the vibration-damping device 2. Furthermore, the vibration-damping device 2 is provided with an attachment 10 with which the beam layout 3 can be attached to the vibration-damping portion 2.

[0016] In another embodiment, shown in FIG. 3D, the corbel 6 comprises a portion 6A, which at mounting extends past the joint 5 between two wall blocks 1A, 1B. The corbel 6 is advantageously mounted, before the next wall block 1B, in the row of wall blocks placed on each other, is to be mounted on the first wall block's 1A end portion 11. In this manner, the corbel 6 forms an aligning means for the next wall block 1B, by the wall block's surface 12 being placed against the corbel portion 6A. Thus, the mounting of the wall block is facilitated.

[0017] In another embodiment according to FIG. 2C, the vibration-damping device's 2 attachment comprises a second corbel 13 or a second bracket, with a portion 14 in parallel with the beam layout 3 and a second portion 15 in parallel with the wall 1, but extending along the beam layout's 3 end edge 16 or short side.

[0018] In another embodiment according to FIG. 2B, the vibration-damping device 2 is arranged between two parallel surfaces 17,18, the one surface 17 accommodated in the wall block 1 and the second surface 18 accommodated in the beam layout 3. The vibration-absorbing device 2 is mounted to one of the two surfaces 17,18 whereafter the beam layout 3 is placed with its parallel surface 18 against the wall block's parallel surface 17, whereby the vibration-absorbing device 2 is positioned between the surfaces.

[0019] According to FIG. 2D, the parallel surfaces 17, 18 can comprise a beam 19 of wood or metal or aluminium, which is mounted on the wall block's 1 surface 20. The beam 19 has a thickness, which is equal to or larger than the width of the vibration-damping device 2. Correspondingly, a similar beam 19 is mounted on the beam layout edge 16. Alternatively, the beam layout's 3 surface layer 21 in the form of a plate of laminated wood or thick building board projects outside the beam layout edge 16 according to FIG. 2A, whereby the protruding portion replaces the beam 19.

[0020] According to FIG. 3B, the vibration-damping device 2 is in its simplest form constituted by a piece of material 22 of a springy or resilient material, for example rubber, or by an elastomeric material, for example polyurethane. Alternatively, the piece of material can be replaced by a spiral spring 23, see FIG. 3A. Yet another alternative is to replace the piece of material by a so-called wave spring 24 as shown in an exemplified form in FIG. 3C. A wave spring comprises a single-turn or multi-turn ring 25 of a flat spring material, to which a wave form 26 is affixed along the entire ring. This gives a plurality of resilient and vibration-absorbing areas, which together can absorb vibrations in a relatively short extent of movement, which gives a reduced built-in height.

[0021] The vibration-damping device is fixed onto the corbel or the parallel surface according to FIGS. 1B and 3D by means of screws 27. A self-drilling screw is mounted first through the one side of the vibration-damping device to keep it in place on the one parallel surface or the corbel, before the beam layout is lifted into place. Subsequently, a second screw is screwed though the beam layout's surface layer or board in the second side of the device in such a manner that the device is fixed without being able to be moved from the location.

[0022] Whether corbels 6, 13 or beams 19 are used in combination with a piece of material 22, a spiral spring 23 or wave spring 24, a spring plate 28 can advantageously be placed between the parallel surfaces 8, 14, 17, 18, 21 and the springs 22, 23, 24. A self-drilling screw 27 is subsequently screwed through the corbel portion 8, 14 and through the spring plate 28. In this manner, a fixed mounting laterally is obtained, but with full freedom of movement in height for the spring. In another embodiment, the spring plate 28 comprises a container with a so-called chemical anchor 29. When the screw is screwed in, the components of the chemical anchor are activated, whereafter the anchor hardens and locks the screw. In yet another variant, the chemical anchor, for example in the form of a two-component adhesive, can be injected under the spring plate before the screw is screwed in, whereafter the chemical anchor hardens through contact with air.

[0023] If a spiral spring 23 or a wave spring 24 is used, a spring guide can advantageously be used. The guide can comprise a sleeve or a short piece of pipe, which sleeve or piece of pipe is attached to one or both parallel surfaces, before the spring is placed above the sleeve or piece of pipe. The guide has been given a diameter, which is somewhat smaller than the spring, and in this way prevents the spring from being moved from the parallel surface, when the vibration-damping device is mounted.

[0024] The present invention is not limited to the description above and what is shown in the drawings, but can be amended and modified in a number of different ways within the framework of the intention of the inventive idea set forth in the following claims.
