Definitions

  • the invention relates to a fastener for fastening heat insulating panels on a substructure with a holding element and an expansion element to be introduced into this.
  • the holding element has one Pressure plate at its upper end, a shaft part that attaches to the pressure plate connects and a spreading area in a lower area. That in that Retaining element to be introduced is designed such that it is up to a lower end position in the holding element can be inserted into the holding element, so that it is the spreading area of the holding element in the inserted state apart.
  • Fastening elements for fastening heat-insulating plates must be attached to the adapted to various application-specific thicknesses of these insulation boards to ensure secure anchoring in the substructure guarantee.
  • a fastening element is presented in DE-OS 196 51 046, in which the length of the holding element, as well as the length of the The screw to be inserted is adapted to the thickness of the insulation board.
  • a similar fastener is also from DE-OS 196 48 823 provided, with an impact socket instead of a screw according to the length to be selected.
  • the object of the present invention is a fastener To provide, in which the expansion element length regardless of the thickness of the fixing insulation board can be kept and in which the proper insertion of the expansion element in the holding element is simple and safe to control.
  • a fastening element for fastening heat-insulating Slabs on a substructure with a holding element and a Spreading element provided, the holding element having a pressure plate on its upper end, a shaft part that adjoins the pressure plate downwards, and has a spreading area in its lower area, and wherein the Spreading element is designed such that it is up to a lower end position in the Retaining element can be inserted into the holding element, so that it is inserted in the State pushes apart the expansion area of the holding element.
  • a position rod is attached to the expansion element in such a way that it is exactly when the expansion element up to the lower end position in the Holding element is inserted is completely sunk in the holding element.
  • the expansion element length must be in a fastener according to the invention can no longer be varied with the thickness of the insulation panels, but can be kept constant. It is sufficient, on the one hand, the length of the holding element between its upper end, d. H. the pressure plate, and the lower one End position, and on the other hand to vary the length of the position bar.
  • the expansion element itself can be used unchanged for all insulation board thicknesses become.
  • the fastening element according to the invention too violent by setting up a position staff Introducing the expansion element into the holding element to ensure the fixed Anchoring the same prevented.
  • the clearly visible complete immersion the position rod in the holding element is namely a sufficient sign for proper assembly.
  • the shaft part of the holding element is made of composed of at least two parts, namely an upper and one lower part. This makes it possible with the respective adaptation to the thickness of the to be fastened, only another upper part of the shaft part to use. The lower part of the shaft part, which contains the expansion area, can then be used regardless of the respective insulation board thickness. This results in clear rationalization advantages.
  • the contact surface between the lower and the upper part of the shaft part for exact mounting of the lower part in the upper part Provide material surveys. It can be ribs and / or raised Trade points. Other structurally selected structures are also possible.
  • the lower end position is a stop, which is formed by the upper end of the lower part of the shaft part.
  • the upper and the lower part of the shaft part are over one Snap mechanism connected together.
  • the lower one shows Part at its end facing the pressure plate an angular head.
  • the upper part then has, for example, two resilient tongues for receiving of the head of the lower part can spring outwards.
  • the position rod preferably has a clamping element at its lower end on to take the position rod with the expansion element when To allow insertion into the holding element.
  • the clamping element it can are, for example, a kind of clip with semicircular arms that grips the expanding element in a clamped manner.
  • the clamping mechanism is preferred positive, so that the position rod is not opposite the expansion element is movable.
  • the expansion element has, for example, at the point where the Position rod to be clamped a corresponding recess for Inclusion of the clamping element of the position rod. It can be for example, around a radial circumference, the shape of the arms of the act clamp-like clamping element adapted recess, the arms of the clamp-like clamping element.
  • a non-positive Clamping effect between the clamping element and the expansion element is also conceivable.
  • the one then given at least downwards relative to the expansion element Movability of the position bar opens the possibility for the Fitter to sink the position rod in the shaft part without the expansion element to have sunk properly.
  • the advantage of overwinding or excessive impact of the expansion element can be avoided remains received however.
  • the position bar has its upper end has a flexible and / or swiveling cover that the Shaft part of the holding element closes when the expansion element is the lower one Has reached the end position.
  • this lid can be in the Uniklappen holding element so that it is flat on or in the insertion opening Pressure plate comes to rest and closes it.
  • the Pressure plate has a corresponding recess for receiving the cover intended.
  • the cover provides protection against plastering penetrating plaster.
  • one of the Position rod independent cap for closing the pressure plate over its Insertion opening may be provided.
  • this cap can be chosen in this way be that it is articulated on one side with the pressure plate and after Insert the spreading element folded by hand and on top of the Pressure plate is pressed. To ensure a secure hold of the cap the cap is palpated with the pressure plate. This can be done, for example be realized that a projection is provided on the edge of the cap, the is pressed into a corresponding recess in the pressure plate.
  • the Cap preferably has the shape of a flat round plate, according to its Press down on the pressure plate to lie largely flat on the top comes and is not a hindrance when plastering.
  • a longitudinal groove in which the position rod when inserting the expansion element can be performed is Appropriately located on the inside of the upper part of the Shaft part a longitudinal groove in which the position rod when inserting the expansion element can be performed. This can prevent that in the event that the expansion element is a screw, the position rod for Screwing in the same with a drill and thereby is damaged.
  • the expansion element preferably has a metallic base body and one Head made of plastic, with the end facing the head of the metallic Base body is provided with a plastic coating. Based on these The arrangement allows the formation of a cold-thermal bridge through the metallic base body is favored, effectively suppress. Preferably closes the plastic head with its underside or the subsequent one Plastic coating the hole at the top of the lower part of the shaft part of the holding element. The additional sheathing of part of the Expanding element shaft following the expansion element head grants a additional radial seal in the lower part of the shaft part of the Holding element.
