Definitions

  • the invention relates to a holding device for at least one mobile partition element, with at least one rail having at least one guide slot for guide rods of partition elements, wherein the holding device along the rail has receptacles for ceiling elements of a cover.
  • the invention further relates to a guide system for at least one mobile partition element having a main arm with a main guide slot and at least one side arm with a Park Operationssschlitz, and a mobile partition wall element.
  • Mobile wall systems also known as partition systems, are used for the variable subdivision of rooms.

  • the individual mobile wall elements are clamped by means of movable elements, so-called Ausfahrtik duplex in the non-actuated state wholly or partially in the mobile wall element. In the extended state they protrude beyond the mobile wall element and are pressed against the ceiling or floor or ceiling rail or bottom rail.
  • a transmission path is that an outer wall of a mobile partition wall element resonates as resonant membrane with sound waves from a room and transmits them via the frame or other solid components to which the outer wall is connected in the interior of the mobile partition element to the other outer wall.
  • the second outer wall then serves as a loudspeaker diaphragm.

  • the said transmission paths for sound by mobile partition walls or mobile partition systems are independent of the materials used in the mobile partition elements. Common materials in this context are metals, wood or plastics or composites.
  • Conventional holding devices for mobile partition wall elements comprise a rail in the form of, for example, a hollow profile with a central guide slot for guide rods of partition wall elements which are suspended on their upper side on a supporting ceiling.
  • the supporting ceiling carries the weight of the mobile wall, as far as the mobile wall elements are not supported yet by means of extended Ausfahrtikmie on the ground.
  • the rail profiles are laterally provided, for example, on their underside with inverted T-profiles, wherein on both sides in each case a horizontal arm of the T-profile protrudes laterally beyond a side wall of the rail profile.
  • On the towering arm of the T-profile there are ceiling elements or panels of a supporting ceiling, so that the suspension ceiling or its ceiling panels or elements are substantially flush with the underside of the rail profile.
  • the T-profiles thus form receptacles for the ceiling elements of the suspension ceiling.
  • US 2001/0032424 A1 relates to a system for concealing guide rails of a mobile partition wall system, wherein a guide rail is directly and extensively connected to two other profiles, which has a support for suspended ceiling elements.

  • the term elastic modulus is understood to mean the technical definition of the static modulus of elasticity.
  • the modulus of elasticity is a measure of how much resistance a solid opposes to its deformation and determines the propagation properties for sound in the solid state. Thus, the propagation velocity of sound in solids and their acoustic characteristic impedance depends on the modulus of elasticity.

  • Many low modulus materials such as rubber, also provide dissipative sound absorption.
  • Such materials have a complex modulus of elasticity, the real part of the modulus of elasticity being related to the above-described effect of sound insulation by reflection at phase boundaries, and the imaginary part of the modulus of elasticity to the dissipative sound insulation.
  • the sound absorbing body "at least substantially" consists of such a material, so to understand that the essential parts of a sound absorbing body consist of such a material, so that no sound bridges of materials with less or Lack of dissipative sound insulation arise over the structure-borne sound can be forwarded undamped or little steamed.
  • the holding device is further developed in that the rail is arranged on at least one upper holder profile and at least one lower holder profile is designed as a receptacle for a ceiling element, wherein the at least one sound insulation body connects the upper holder profile with the lower holder profile.

  • the cavity is at least partially filled with a Dämmmasse.
  • a Dämmmasse next to a turn rubber-elastic mass and any other heavy mass, such as cement, plastic filling, metal or the like suitable, which means that the heavy Dämmmasse is very difficult to vibrate in the cavity and thus sound bad of a ceiling element transmits to the rail profile.
  • the cavity is designed to receive electrical cables.
  • the interior of the rail profile, in which carriages of the partition wall elements are moved can be mechanically separated from the space in which electrical lines are guided. In this way, electrical lines even when mounting a holding device according to the invention be installed immediately, while otherwise would have to be postponed in a separate assembly step.
  • the rail and the upper holder profile by means of a clip or locking mechanism with grooves and hooks are connected to each other.
  • a clip or locking mechanism with grooves and hooks are connected to each other.
