Definitions

  • the invention relates to a support body for mutually fixing supporting elements arranged on both sides of a non-load-bearing insulation layer.
  • Support elements of the type mentioned are z. B. used in the construction of roof insulation.
  • a corresponding roof insulation is e.g. B. from the European Patent application EP 0 222 284-A2 known.
  • a layer of heat-insulating plates is placed on a base and in load-bearing places, for. B. provided with holes over a rafters.
  • a layer of heat-insulating plates is placed on a base and in load-bearing places, for. B. provided with holes over a rafters.
  • z. B. connected to the rafters.
  • An outer cover is then attached over the plates and connected to the supporting bodies.
  • the support bodies hold the insulating plates lierplatten shear-resistant on the base and carry the cover.
  • a device for fixing an insulation layer on a roof which has two vertical side walls and a horizontal wall connecting them, in such a way that a U-profile is formed.
  • There are tips on the undersides of the vertical side walls which can be driven into a base.
  • the U-profile is pressed into the insulation layer from above.
  • On the horizontal connecting wall there is a plate with an upstanding tip for attaching a slat.
  • the U-shaped element is attached to the base with a nail.
  • GB-2 209 774 A discloses a conical support body for use in fastening corrugated plates to a base.
  • the rotationally symmetrical support body is completely open on one side and closed on the other with a lid.
  • the lid has a centrally arranged hole for a fastening nail.
  • Inside the support body there are longitudinal ribs running in the axial direction, which, however, leave a central cylindrical cavity free for the nail.
  • the support body serves to support a wave that bulges away from the base.
  • the nail penetrating the support body in the axial direction presses the shaft onto the support body.
  • the Hollow bodies according to D2 have the function of providing a contact surface when driving in a nail (6) (see page 1, 2nd paragraph and page 4, 1st paragraph).
  • a self-drilling fastening plug is known, with which a corrugated plate can be fastened to a carrier.
  • the anchor is in principle a long rod, the front end of which is provided with a drilling tip.
  • Set back from the tip is a ring-shaped sleeve that lies tightly on the rod. Its axial surface directed towards the tip of the rod is designed for drilling.
  • the dowel can be placed on a drilling machine and drilled through the corrugated plate and the insulating material into an underlying carrier.
  • the tip acts as a pre-drill and the sleeve as a full drill.
  • the cuff does not penetrate the carrier, so the drilling process stops automatically.
  • With a screw device attached to the upper end of the dowel the corrugated plate against the insulating material or. the carrier are pressed.
  • the object of the invention is to improve a load-bearing support body of the type mentioned at the outset in such a way that it allows quick and easy assembly and at the same time offers optimum thermal insulation.
  • this support body can be driven into the insulation layer without first drilling a hole.
  • the cavity receives the insulating material that previously had to be drilled out in the prior art. Since the cavity is filled with the material forming the desired insulation layer in the assembled state, optimal thermal insulation is ensured.
  • the jacket should displace as little volume as possible so that the support body can also be used with insulation materials that are only slightly compressible. At the same time, however, it should ensure a sufficient load-bearing capacity of the support body in the direction of penetration.
  • the wall delimiting the cavity is preferably of essentially cylindrical or conical shape. Such shapes are not only mechanically stable, but can also be easily z. B. drive in by rotation.
  • the support body can be stacked due to a slightly conical shell inclination.
  • the support body is to be driven into poorly compressible insulation layers, then it may be advantageous to provide the jacket with suitable slots or holes through which crumbled material can escape from the cavity.
  • a fastening means that extends axially through the cavity and protrudes from the cavity can be provided.
  • the fastening means can both be fixedly connected to the support body and also represent a separate, detachable individual part.
  • fastening means is designed as a screw and that the jacket is provided with a cutting edge for cutting insulating material.
  • a support body can be driven through the insulation layer in the manner of a hollow drill and at the same time fastened to the supporting element.
  • connection means are provided on the support body which allow the support body to be fastened with the aid of a drilling machine.
  • the jacket can at least at the edge that can be cut from a material that is strongly abraded during drilling of the insulating material provided, so that the cutting ability has largely dropped after penetration of the insulation material.
  • the "drill bit" of the support body wears out so quickly that the sensitive layer (e.g. film) cannot be cut through.
  • the edge which can be cut is set back slightly and is formed on the side of the jacket.
  • the jacket is a cylindrical or conical jacket-shaped plastic ring.
  • the plastic ring In the axial direction, the plastic ring is closed on one side by a wooden or plastic cover. The opening axially opposite the cover remains.
  • a lid made of wood has the advantage that supporting elements (such as roof battens and the like) are easy to attach to it. With a plastic lid, however, the risk of rotting is avoided. In the latter case, the cover and wall form a one-piece molding.
  • the cover offers enough volume for driving in screws or nails, but without significantly reducing the cavity, it has a greater thickness near the axis of rotation of the support body than far from the axis. It preferably penetrates conically into the cavity.
  • the support body in two parts, the first part being a hollow body (plastic ring with cover) and the second part being a spacer element which can be fastened to the hollow body.
  • a water and / or vapor barrier seal can be provided between the two parts, which prevents the penetration of water into the insulation layer and the rusting of the driven nails.
  • the support body according to the invention is particularly suitable for building insulation structures (e.g. for roofs) in which between two stable boundary walls there is a space with insulating material.
  • the support bodies enable the boundary walls to be mutually supported through the intermediate space filled with insulating material.
  • a large-area insulation film (sub-roof) is fixed between the two parts.
  • Fig. 1 shows schematically a section through a construction which uses the support body according to the invention.
  • a battens 2 (roof formwork) is nailed onto a rafter 1.
  • a vapor barrier 3 (or vapor barrier) is applied to this battens 2, which acts as a load-bearing boundary wall. It is typically covered by a film, e.g. B. formed from aluminum-coated roofing felt.
  • An insulation layer 4 follows the said vapor barrier 3.
  • B. from thick thermally insulating mats (made of rock wool, foam and. Like.). This is followed by a sub-roof 5.
  • a counter battens 7 which represents the second supporting boundary wall of the insulation structure.
  • a ventilation space 6 can be provided between the counter battens 7 and the sub-roof 5. This is particularly common for roof insulation.
  • the battens 2 and the counter battens 7 are stably connected to one another by suitable support bodies 8.1, 8.2.
  • the support bodies 8.1, 8.2 also keep the insulation layer from shifting.
  • Fig. 2 shows such a support body 8.1 in axial section. According to a preferred embodiment, this is in two parts.
  • the first part is essentially a hollow body, while the second part is a spacer.
  • the first part has a cavity 11 which is delimited transversely to the direction of penetration 20, preferably by a cylindrical jacket 9.
  • this coat 9 it can be, for. B. is a cylindrical plastic ring. On one side, this plastic ring is closed with a cover 10. The axially opposite side of the plastic ring is completely open.
  • a screw 12 fastened to the cover 10 pierces the cavity 11 in the axial direction and protrudes from the open end of the support body.
  • the screw 12 can be firmly anchored in the cover 10 so that it can only be rotated together with the first part.
  • the screw 12 is used to attach the support body to the rafters 1 (Fig. 1).
  • the edge of the jacket 9 is provided with a surface 13 that can be cut at the open end of the support body.
  • the cutting ability is by a pointed tapered edge. It serves to cut through the insulation layer 4 when driving in the support body. Since thermal insulating materials are usually very easy to cut, the edge does not require any special material hardness.
  • the insulation layer to be described below is cut in the present case by the lateral, slightly recessed cutting surface 13.
  • the lid 10 is preferably made of wood or plastic. In order to drive in nails or Fastening screws to have enough volume available, it is advantageous if the lid near the axis of the cavity 11 is thicker than at the edge (in the case 9). So the lid z. B. conically penetrate into the cavity 11. The advantage of such a conical cover 10 is that it only slightly reduces the cavity 11, but offers sufficient depth for nails or screws.
  • a bore 14 is provided on the (axial) outside of the lid 10 .
  • a screw 15 of the spacer 16 are screwed. In this way, the two parts can be releasably connected to one another.
  • a seal 17 (e.g. a sealing ring) can be provided to protect against water penetrating between the two parts. This creates a so-called nail seal, which prevents water from penetrating through the sub-roof 5 into the insulation layer when nails or screws have been driven into the cover 10.
  • the bore 14 is designed as a connection means for a drilling machine.
  • a connection means z. B. serve a hexagon or bayonet connection.
  • the screw 15 of the second part is then replaced accordingly by a suitable bayonet insert.
  • Fig. 3 shows a preferred support body in side view.
  • the jacket 9 plastic cylinder
  • the plastic cylinder has a sawtooth-shaped edge (saw teeth 18).
  • the screw 12 protrudes over the edge 13.
  • the vapor barrier 3 (film) is first applied to the battens 2.
  • the insulation mats (insulation layer 4) are then laid over the entire roof in a shear-resistant manner on the film.
  • the support bodies are now used to attach the insulating mats mentioned.
  • the lower part designed as a hollow body (cf. FIG. 2) is placed on a drilling machine and drilled through the insulation layer 4. While the screw 12 penetrates the battens 2 and the rafters 1, the cutting edge 13 eats through the insulating mats. According to an advantageous embodiment, the cutting surface 13 becomes visibly blunt during drilling. If the jacket has now penetrated to the film (vapor barrier 3), the forward movement in the penetration direction 20 is stopped because the edge 13 which was once capable of being cut cannot penetrate through the film.
  • the support body can easily be in one piece.
  • a separable spacer element can be dispensed with if the insulation structure is not used for a roof but for a wall.
  • the support body can equally well consist of more than two parts.
  • the axial screw 12 can, for. B. be a separable element of the hollow body.
  • a plug connection is also suitable for fastening the spacer element on the hollow body. That is, one part has a recess (depression) and the other part has a corresponding nose. Instead of a pair of recesses - nose, several corresponding pairs can of course also be provided.
  • Wood is the easiest material to work for the lid 10 or spacer 16. Instead of wood, composite materials are also quite suitable, which have similar properties in terms of nailability and machinability. If nailing can be dispensed with, the spectrum of suitable materials is expanded anyway. Non-rotting or hardly rotting materials are generally preferred.
  • the hollow body can be made of plastic and the spacer element made of wood.
  • the two parts can then advantageously be connected to one another by a bayonet connection or a plug connection.
  • the cover can be provided on the conical inside (i.e. in the cavity) with means for crushing the insulation material.
  • means for crushing the insulation material e.g. B. Styrofoam are scraped away so that space is made for the tip of the cone.
  • the crumbled insulation material can e.g. B. are conveyed out of the interior of the hollow body by suitably provided slots of the jacket.
  • the optional spacer element 16 generally has the same outer shape and the same diameter as the hollow element. Under certain circumstances, however, it can be of advantage to give the spacer element 16 a different dimension or a different shape.
  • the invention provides a support body which significantly facilitates and accelerates the assembly of insulation structures.
