Definitions

  • the present invention relates to a device for fixing an insulation panel to a substructure with simultaneous thermal insulation closure, in particular a dowel for recessed mounting in an insulation board with releasably held on the dowel insulating frond, and a corresponding method.
  • the holding elements serve to fix the insulation board to a substructure, for example to a building wall.
  • the holding elements usually consist of a dowel, a spreader and a pressure plate.
  • a borehole is first drilled in the substructure - in the building wall - through the insulation board.
  • the dowel and the expansion element are introduced, whereby an anchoring in the substructure can be created by means of a Sp Dahlfix ist.
  • the dowel for example, a spreading zone, which can be widened by the introduced expansion element, creating a deadlock in the substructure is created.
  • spreading elements are also known, which can be screwed directly into the substructure in the same way as screws.
  • the pressure plate of the holding element At the end of the holding element, which is opposite to the Sp Dahlfix ist is the pressure plate of the holding element.
  • the pressure plate of the holding element rests flat on the insulating plate and can exert pressure on this, so that the insulating plate is pressed against the substructure. This pressure is generated by the fact that the expansion element is driven into the substructure, so that the distance between the pressure plate and substructure is lower, so that the pressure plate exerts pressure on the insulation board, which is located between pressure plate and substructure.
  • such holding elements have the disadvantage that the pressure plate rests flat on the insulation board and the spreader, which is attached to the pressure plate, thus extending from the surface of the insulation board into the substructure, creating a thermal bridge is created, which impair the insulation effect can. This is especially true if the plurality of holding elements is considered, which is used on a building wall, so that this Dämm Signsbeeintr founded can not be negligible, especially if the spreading elements used are made of metal. Furthermore, the flat contact of the pressure plate has the disadvantage that no homogeneous surface is formed, so that later plastering is difficult.
  • the pressure plate is recessed in newer systems set in the insulation board and the resulting recess, which is often referred to as a sink hole is closed by means of a Rondelle, which consists mostly of insulating material, after mounting the support member to a thermal insulation closure to produce, as this example in EP 2 049 745 B1 is shown.
  • a Rondelle which consists mostly of insulating material
  • the device according to the invention for fastening an insulation panel to a substructure with simultaneous thermal insulation closure has an expansion element and a pressure plate.
  • the expansion element has two opposite ends, wherein one end is configured for fixing the expansion element in the substructure.
  • this end may for example be designed to cooperate with a dowel located in the substructure or the end may have a thread which can intersect in the substructure.
  • the other end of the expansion element is connected to the pressure plate.
  • the pressure plate has a side contacting the insulation panel and a side facing away from the insulation panel.
  • the pressure plate has an upper side, namely the side facing away from the insulating plate and a lower side, namely the side facing the insulating plate.
  • the device also has a Dämmstofondondelle.
  • the pressure plate has a means for holding the Dämmstofondondelle. This holding is a releasable hold. If a tensile force is exerted on the insulating material, which exceeds the holding force, the Dämmstofondondelle detached from the pressure plate.
  • the Dämmstofondondelle be arranged on the top of the pressure plate and held there by the means for holding.
  • the Dämmstoffrondelle itself preferably consists of a material which has similar thermal insulation properties, such as the insulation board in which the device according to the invention is set.
  • the device according to the invention thus provides a device which makes it possible to fasten an insulation panel to a substructure by means of a retaining element from spreader and pressure plate with simultaneous thermal insulation of the recess formed by recessed sink hole by means of a Dämmstoffrondelle.
  • the thermal insulation shutter is produced without further necessary step.
  • the device according to the invention can be used for different thicknesses of insulating materials and different setting depths, since the insulating material can detach from the pressure plate when setting. This can thus result in different distances between the Dämmstoffrondelle and the pressure plate.
  • Another advantage of the device according to the invention is that the expansion element and the pressure plate, as well as the Dämmstofondondelle held thereon can be applied to a setting tool in one step, since the parts can already be put together before. A cumbersome subsequent setting the Dämmstofondondelle deleted.
  • the means for holding a circumferential edge extending substantially perpendicular to the pressure plate in the direction of the Dämmstoffrondelle can, for example, surround the pressure plate facing part of the Dämmstoffrondelle and hold the Dämmstoffrondelle means of a clamp connection.
  • the peripheral edge may additionally have a peripheral elevation directed towards the center of the pressure plate, which reduces the inner diameter of the edge at this point. This survey can increase the clamping effect of the edge.
  • the inner diameter of the edge may be larger close to the pressure plate than further away from it, and the Dämmstoffrondelle may have a reverse course to outer diameter in the area surrounding the edge.
  • the two parts alone by their shape conditionally exert a certain holding force on each other.
  • a three-point fixing can be provided, so at three points from the pressure plate substantially vertically upwardly extending elevations, which are each offset by 120 ° and hold the Dämmstoffrondelle on the pressure plate by means of clamping connection.
  • the device has at least one means to produce a recess in the insulation board and thus a deep set - a recessed mounting - to allow.
  • the created recess is also referred to as a sinkhole.
  • the pressure plate has at least one opening. This can be advantageous if the sinkhole is not formed in the insulation board or not only by compression, but by scraping or milling.
  • the thus dissolved material of the insulation board can then pass through the at least one opening from the bottom of the pressure plate to the top of the pressure plate and there, for example, collected or collected.
  • the number of openings and their configuration is arbitrary and is selected by the skilled person depending on the insulation material used for the insulation board, as well as the way the material of the insulation board is scraped off or milled. In this case, for example, the opening itself also have at least one means for scraping or milling off the insulation board.
  • an edge of the opening may extend at an angle from the plane of the pressure plate towards the insulation panel and thus scrape or scrape the insulation panel when the pressure plate contacts the insulation panel and the pressure plate is rotated.

  • This recess defines a clearance with the pressure plate. In this space, if the pressure plate can penetrate through at least one opening through the material, the scraped or milled insulation material can be collected. This has the advantage that the scraped or milled insulation material does not enter the environment and can contribute further to the insulation effect.
  • the Dämmstoffrondelle on the pressure plate facing side has an outer diameter which is smaller than the outer diameter on the side facing away from the pressure plate.

Accordingly, the Dämmstofondondelle does not experience the same input as the pressure plate and a tensile force is exerted on the Dämmstofondondelle. If the tensile force exceeds the holding force exerted by the means for holding, the insulating material disc dissolves from the pressure plate.
  • the release of the Dämmstoffrondelle of the pressure plate when setting the device according to the invention also has the advantage that a space between the Dämmstoffrondelle and the pressure plate is created, which can be filled with scraped or milled insulation material, without this enters the environment.
