Definitions

  • the present invention concerns a sound-damping coupling according to the introduction to patent claim 1.
  • Sound-damping couplings of this type are used principally for prefabricated elements for domiciles, in which each element forms a prefabricated unit of height one storey.
  • the function of the sound-damping coupling is to break the contact between the prefabricated wall and floor structure elements to each other, such that structure-borne sound is not transferred between storeys.
  • the function of the couplings is to couple the elements in such a manner that sound that propagates through the structure of the building is not transferred between the walls and floor structures of two storeys that are placed one on top of the other.
  • structure is used to denote essentially only the wall structures and floor structures that bear a load, thereby established sound-protection classes require an overall consideration of the sound-proofing between apartments.
  • the floor structure is attached to the wall by means of draw rods enclosed within the wall.
  • the draw rods thus extend through a first and a second element, which elements consist of solid wood and are components of the bearing wall, of which the first element is located above a third element, which in a similar manner also consists of solid wood and forms a part of the floor structure.
  • This third element is in turn placed on and supported by the second element, which consists of solid wood, of the bearing wall.
  • the draw rods that are enclosed within the wall are provided with turning means in the form of nuts that are in threaded interaction with a thread that runs along the rod.
  • the elements of solid wood that are in contact with each other can be placed in force-bearing contact with each by influencing the nuts in a turning manner by the use of a turning tool such as a spanner or similar.
  • a turning tool such as a spanner or similar.
  • members of sound-damping elastomeric material have been arranged between both the nut and between the neighbouring elements, such that the elements are not in immediate contact or under the immediate influence of each other, but are in sprung, relaxed, contact against each other.
  • the nuts are accessible through openings in the wall, such that they can be turned by the said hand tool.
  • the damping material SYLOMER® has proved to be particularly suitable for building purposes, not least due to its high resistance to aging, its elastic properties, and its inner damping capacity.
  • a disadvantage of known sound-damping couplings that are used at the point where a wall meets a floor structure is that a significant part of the installation work must be carried out from underneath, from the lower surface of the floor structure. Installation work that must be carried out from underneath involves uncomfortable working postures and it is both time-consuming and hard work for those who carry it out.
  • a second problem is that adjustment of the nuts arranged on the draw rods as turning means for achieving contact between the elements, which consist of solid wood, of the floor structure and the wall cannot be carried out with the aid of machines: it must be carried out by hand by the means of spanners or similar hand tools. The installation work is thus both difficult and time-consuming.
  • a third problem with the known extended draw rods in the wall is that they limit, due to their relatively long length, the opportunities of the architect to choose freely the locations of windows in the wall, and they affect in a limiting manner the maximum size that the windows can occupy in the walls.
  • US 3 665 662 discloses a coupling comprising all the features of the preamble of claim 1.
  • FR 2 841 580 discloses a round-damping coupling comprising an elastomeric material between building elements.
  • One aim of the present invention is therefore to achieve an improved coupling of the type described in the introduction, by which the disadvantages of previously known couplings described above are eliminated.
  • the sound-damping coupling is characterised in the first hand in that the screw means comprises wooden screws, the extended central part of which has the form of a pin or cylinder and is accommodated in a vertically drilled hole in the third element, the head of which serves as turning means and is turned upwards from the upper surface of the floor structure, and whose end, which tapers and is provided with an external thread, is attached to the second element through self-tapping immediate screw-driven insertion, whereby the first element is located in position on the third element through an installation that occurs after the joining of the second and third elements, and attached to the same by screwing.
  • the screw means comprises wooden screws, the extended central part of which has the form of a pin or cylinder and is accommodated in a vertically drilled hole in the third element, the head of which serves as turning means and is turned upwards from the upper surface of the floor structure, and whose end, which tapers and is provided with an external thread, is attached to the second element through self-tapping immediate screw-driven insertion, whereby the first element
  • the post-installation of the first element takes place through interaction with a control means arranged on the floor structure on the third element or in association with this.
  • the control means is in this case so designed that the first element is bound by design to the third element, prevented from horizontal motion in at least one direction.
  • the installation work can thus be easily mechanised and carried out by means of motor-driven power tools or similar.
  • the manufacturing tolerances for both the floor structure and the wall can be kept at low levels in that the third element is fixed to the second element through self-tapping free screw-driven insertion.
  • Figure 1 shows a partially sectioned side view of a horizontal floor structure element and two vertical wall elements that are coupled to the floor structure element according to a first embodiment of the invention, whereby the wall is of standard beam design
  • Figure 2 shows a partially sectioned side view of a horizontal floor structure element and two vertical wall elements that are coupled to the floor structure element according to a second embodiment of the invention in which the wall is of a solid design.
  • Figure 1 shows a sound-damping coupling between building elements that consist of solid wood of which a first element 11 and a second element 11' are components of parts of upper and lower sections of a load-bearing vertical wall, while a third element 12 is included as a part of a horizontally oriented floor structure, and which third element is supported resting on the second element 11', while the first element 11 is supported resting on the third element.
  • the load-bearing wall and the floor structure of which the said building elements form a part otherwise comprise a number of other materials that are commonly found in floor structures and wall structures such as, for example, insulation material, wood fibreboard, other board, etc., which structures are prefabricated to completed units that can be installed at the building site.
  • the coupling comprises first and second sound-damping members, generally denoted by reference number 13 and 14, respectively, of material that can be deformed in an elastomeric manner, located between at least two of the elements described above, the task of which is to form a sound-insulating bridge between the second element 11' and the third element 12.
  • the sound damping members form a sound-insulating bridge at the point of contact between the wall and the floor structure.
  • the first sound-damping member 13 of the coupling comprises a track 16 that is arranged at one element 11' of the said two elements and that lies in the longitudinal direction of the wall, and which extends in a vertical direction into this from the horizontal principal surface of the third element 12, which surface faces towards the element 11', and a strip 17 of material that can be deformed elastomerically located in the track, which strip when inserted into the track has a height that exceeds the depth of the track.
  • the strip 17 is manufactured from an elastic rubber material, for example, the commercially available damping material that is marketed under the trade name of SYLOMER®.
  • a series of vertical drilled holes, generally denoted by the reference number 18, is arranged in the third element, which holes are arranged in a row at equal separations, extending along the longitudinal direction of the wall. It is, of course, conceivable to arrange the holes in rows on opposite sides of the strip 17 or in patterns of other formations, even if this is not shown in the drawings.
  • the holes 18 are circular and they are designed with stepwise depressions in the third element 12, demonstrating an internal profile that is broader at the top at 19 than it is at the bottom at 20.
  • the region of transition between the upper broader internal profile 19 and the lower more narrow internal profile 20 is designed as a plane 21 that is parallel with the principal plane of the third element 12.
  • the third element 12 is attached to the second element 11' by means of screw means generally denoted by the reference number 22 inserted into the holes 18, which screw means are here constituted by conventional screws, i.e. screws of toughened, anti-rust treated stainless steel intended for the joining of and fixing of wooden constructions.
  • the said screw means 22 are thus of the type that comprises a screw head 23 designed such that it can be screwed and unscrewed with a screwing tool, a central pin or part formed as a cylinder 24, and an end part 25 provided with an external thread, where it is an advantage if the said end part that is provided with a thread is, as is the case with available wooden screws, conical or tapers down towards the free end in order to facilitate the screwing in to the material that the screw is to fix.
  • the screw head 23 may demonstrate a number of different forms for interaction with the above-mentioned screwing tool, but it is an advantage if it is designed for interaction with a machine-driven rotating sheath, preferably of hexagonal type or torx-type. It is appropriate that the said screw means 22 is constituted by what are known as "French wooden screws", i.e. wooden screw of relatively large dimensions with a hexagonal head, the threaded part of the screw being essentially tapered down towards the free end.
  • the third element 12 is attached to the underlying second element 11' through the screw means 22 that have been inserted into the holes 18 being driven into the second element 11' through self-tapping immediate screw-driven insertion.
  • the head 23 of the screw means 22 is inserted depressed in the upper broader internal profile 19 of the step-formed hole 18 and it is turned upwards such that the screw head 23 is to be simple to access for installation work from above by personnel located on the floor structure, and through turning interaction with screwing tool such as, for example, a rotating machine-driven sheath.
  • the screw head 23 that has been inserted into the hole 18 through depression also has the advantage that it facilitates the installation of the upper first part 11 onto the third element 12, in which the first part 11 has been placed in position resting on the strip 17.
  • the invention comprises a second sound-damping member 14 of material that can be elastomerically deformed, the task of which is to form a sound-insulating bridge between the second element 11' and the third element 12 in order to break the transmission, if any, of sound through the screw means 22.
  • the second sound-damping member 14 comprises a body of an elastomeric material arranged between the head 23 of the screw means 22 and the third element 12, and between the central pin or cylinder-formed part 24 of the screw means 22 and the said third element 12.
  • the interface between the said parts 22 and 11 comprises a body 26 of elastomeric material having the form of a tube inserted into a space 27 that is limited between the central pin-formed section 24 of the screw means 22 and the side wall 20 of the hole at its lower more narrow internal profile, and one or several layers of flat, hollow bodies 28 similar to washers, placed on top of each other.
  • a washer 29, provided with a hole, of some relatively stiff and highly durable material such as, for example, steel is placed immediately under the head 23 of the screw means 22 and the one or several flat, hollow bodies 28 of elastomeric material similar to washers.
  • the first element 11 is placed resting on the third element 12 and it is post-installed onto it, i.e. it is installed onto the third element at a stage that follows the joining between the second element 11' and the third element 12.
  • the third element 12 comprises a control means 30, the task of which is to facilitate the location and the fixing of the first element 11 onto the third element 12.
  • the task of the control means 30 is to hold the first element 11 resting on the strip 17 that has been inserted into the extended track 16 vertically above the second element such that the said elements are located linearly above each other (one of them above the other) while they are fixed by means of the fixing means 32.
  • the control means 30 comprises a guide rail of solid wood attached to the third element with fixing means 33 in the form of nails.
  • the fixing means 32 comprises in the embodiment of the invention described here a screw that has been inserted into a drilled hole 34 in the control means 30 that is coupled to the first element 11 through immediate self-tapping screw-driven insertion. It is an advantage if the screws that function as fixing means 32 can be arranged in the control means 30 in advance by the use of pre-insertion.
  • Figure 2 shows the sound-damping coupling according to the invention in a design adapted for the meeting between a third element 12 that is a component of a horizontal floor structure and a load-bearing vertical wall of solid type of which both the first element 11 and the second element 11' are components.
  • This sound-damping coupling differs from the coupling described above in that the first sound-damping member 13 and the screw means 22 are positioned linearly above each other (one of them above the other).
  • the first sound-damping member 13 comprises also here a strip 17 that has been inserted into a track 16 arranged in the second element 11' in such a manner that the strip when inserted into the track has a height that exceeds somewhat the depth of the track.
  • the strip 17 is provided for this purpose along its length with a number of holes 35, distributed at equal distances from each other, through which the screw means 22 can pass for insertion at its forward threaded part 25 into the second element 11' into which the screws are to be fixed.
  • control means 30 that are used in this embodiment of the invention differ from those that have been described above in that the control means comprise an angled fitting of metal attached by screws on the third element 12.
  • the first element 11 and the third element 12 are attached to each other by means of fixing means 32 that extend through holes 34 located in the said angled fitting.
  • the present invention is not limited to that which has been described above and that which is shown in the drawings: it can be changed and modified in a number of ways within the framework of the innovative concept specified by the attached patent claims. It is thus possible within the said framework to arrange the bodies of the sound-damping members of material that can be deformed in an elastomeric manner in any shape at all that is suitable for preventing the transmission of structure-borne sound between walls and floor structures.
