Definitions
- the invention relates to a mounting component for external thermal insulation systems.
- Thermal insulation composite systems are facades in which the heat-insulating lining on the component, e.g. Concrete wall, is stuck.
- Different assembly components for thermal insulation composite systems are known. Basically, two categories can be distinguished from such assembly components:
- the assembly component In a first category, the assembly component is fastened to the supporting base, which also carries the ETICS. In a second category, the assembly component is attached to the thermal insulation layer of the ETICS and is therefore only indirectly connected to the substrate.
- the present invention relates to a mounting component of this second category.
- Such components transmit the load attached to them to the thermal barrier coating. They usually consist of a prismatic foam body with a density that is significantly higher than the density of the thermal insulation layer of the ETICS.
- These assembly components have formerly room weights of 217 kg / m3, but recently only 170 kg / m3 EPS (expanded polystyrene) for screw fixings (ZyRillo®, Rondoline® EPS and Quadroline® EPS from Dosteba AG) and 200 or 300 kg / m3 PU Rigid foam (rigid polyurethane foam, Rondoline® PU, Rondoline® PU and Quadroline® PU from Dosteba AG) for pressure-load-bearing assembly components.
- the aforementioned assembly components are straight, cylindrical body formed with a circular, rectangular or square base.
- a phenolic resin plate which metric threads can be screwed into this phenolic resin plate.
- a rondelle is known, which is cast from polypropylene. This 10 mm thick roundel (DoRondo® from Dosteba AG) has a diameter of 90 mm, on the inside a block structure, and its circular outer side is perforated. Sheet metal or wood screws can be screwed into this rondelle.
- the EP-A-1 650 368 discloses a closure cap for a fastener assembly for spaced attachment of an article to a substrate.
- This has a base plate with a passage opening for an anchoring element of the fastening arrangement a spaced apart from the outer circumference of the base plate projecting, circumferential first web and a circumferential in the region of the passage opening second web.
- a collar is provided with a contact surface, which rests in the mounted state on the inner wall of a circular bore in the thermal insulation material.
- an anchoring element directly in the ground for example a Concrete wall, anchored.
- a cylindrical spacer is slipped with a central opening for the anchoring element.
- the fastening arrangement described has the advantage that it can absorb large tensile forces, since the anchoring element is anchored in the concrete wall.
- the disadvantage, however, is that the anchoring element is a cold bridge.
- the base plate is arranged over the plaster.
- the DE-OS-2402249 describes a ventilated facade element for attachment to building walls.
- a facade panel is fastened by means of a fastener to a building wall.
- the fastening element consists of a respective spacer, a mounting sleeve with trained as a pressure plate head, a rod anchor and an anchoring element in the facade panel to be fastened.
- insulating elements are underlaid at various points. Again, the attachment of the facade panel is done directly in the building wall.
- the DE-OS-103 61 751 discloses a dowel for thermal bridge-free attachment of various facade components to variable insulation thicknesses.
- This anchor is made according to one embodiment of plastic and has a substantially round plate, which projects at a distance from the circumference of a circumferential ridge. In the center of the plate, a hole for a self-tapping thread M8 and an outer and inner hexagonal tool holder is provided.
- the plate has a plurality of concentric pitch openings, between which optionally the webs can be removed prior to assembly to employ various circular installations. In the concentric openings can after plastering the dowel plate Dowel anchors are anchored in the facade.
- the dowel plate has milling cams on the underside in order to work out the insulation material to the extent that it is possible to achieve even plastering in the desired layer thickness. Thereafter, the protruding hexagon head is shortened with the knife so far that this central elevation determines the layer thickness of the plaster above the dowel. In the cleaned and deposited with plaster mortar then the dowel plate is pressed and then covered over area.
- An advantage of this dowel plate is that various components can be attached thereto. However, the dowel plate can absorb only low tensile forces. If you want to absorb greater tensile forces, then this must be anchored with screws in the facade.
- a mounting component according to the preamble of claim 1 characterized in that the stiffening structure is formed or vorgeh Scientific inside the fastening body and / or executed as a cover closes the second end of the cylindrical fastening body.
- the mounting component according to the invention has the advantage that it is particularly suitable for installation in polystyrene insulating boards, in particular EPS insulating boards. Components can be fastened to the bolting plate by means of self-tapping screws. The fact that the fastening body is provided with a stiffening structure, there is no risk that the mounting member is compressed when transverse forces occur.
- the mounting component has the particular advantage that in the installed state no thermal bridges with the background are formed.
- connection of the assembly component with the insulation board is preferably exclusively via an adhesive connection, no passages for an anchor element are provided in the assembly component, ie the attachment of the inventive element takes place without an anchor.
- the assembly component can also be pressed into only one hole of the EPS insulation, provided that no large pull-out forces act on the assembly component.
- the stiffening structure of the fastening body may be provided in the interior thereof.
- an insert part may be provided which can be inserted or set in the fastening body. Purpose of the insert is to ensure the dimensional stability of the mounting body.
- ribs or struts may be formed in the cavity of the fastening body. These ensure that the attachment body is dimensionally stable and has the desired rigidity.
- a lid with which the second end of the cylindrical fastening body is closed can be additionally equipped with ribs, an inwardly projecting collar or edge. The lid itself is connected to the fastening body by means of gluing, welding, encapsulation, snap connection, etc.
- the fastening body has a peripheral wall and concentric with the peripheral wall a hollow cylinder, wherein ribs extend radially between the hollow cylinder and the peripheral wall.
- the hollow cylinder with the ribs is integral with the lid. This structure can be inexpensively produced as an injection molded part.
- these blind holes have the advantage that material can be saved can, and on the other hand, that the cycle time in the manufacture of the mounting part can be very short, since the material of the screw plate cools quickly.
- peripheral wall extending in the axial direction profiling.
- This can for example be formed by a wave structure of the peripheral wall similar to a corrugated metal.
- the axially extending recesses on the peripheral wall serve to receive the radial ribs.
- the assembly component is advantageously composed of a first part comprising the screwing plate and the fastening body and a second part comprising the cover, if appropriate with an integrally formed additional stiffening structure.
- a mounting part can be inexpensively produced from two injection molded plastic parts.
- plastic polystyrene not foamed
- polypropylene polyethylene
- other thermoplastics come with similar properties in question.
- the assembly component according to the invention has in common that it has a straight, quasi-prismatic or cylindrical body of a certain depth, which is designed to be arranged inside and fastened to a thermal barrier coating of a composite thermal insulation system.
- the mounting part has in common with the DoRondo®-PE, that it is made of a non-foamed plastic and has a screwing, in the front side at a plurality of locations, one or more screws are screwed.
- a sequence of two layers is formed in the direction of the depth of the mounting component. These two layers are in fact the bolting plate to be arranged on the outside and a depth layer adjoining this bolting plate, which is also referred to below as a fastening body.
- the screwing plate serves to receive screws.
- the attachment body is used to transfer the from the screw into the Mounting component introduced forces via a large area on the material of the thermal barrier coating.
- At least the fastening body has both a cavity portion and a solid wall portion, wherein the solid wall portion of the fastening body is less than the solid wall portion of the screwing.
- the screwing plate can basically be designed without cavity portion. However, a certain void content is advantageous, albeit a lesser one than in the case of the fastening body. This stratification allows the realization of a majority consisting of solid material Verschraubungsplatte in the wood and / or sheet metal screws are screwed. Due to the high insulating value of the mounting component and its attachment in the EPS insulating board by means of an adhesive, the insulating value is not significantly reduced at the location where the mounting member is disposed in the insulating layer.
- the high void content of the largely hollow fastening body ensures a thermal insulation layer after all approximated insulation. Furthermore, material can be saved in the deep layer necessary for the load transfer thanks to the increased void content. This material saving also has the advantage of shorter cycle times during spraying and better material properties thanks to the coolability of the plastic in the mold.
- the mounting body may be formed in a simple embodiment by an outer, circumferential wall with a single cavity between the wall.
- a stiffening structure is advantageously formed in the interior of the fastening body.
- Such a stiffening structure has a plurality of cavities comprised of stiffening walls. This stiffening structure, whether encompassed by a wall or not, ensures that the fastening body is not deformed by the contact pressure of the thermal barrier coating.
- the cavity or the cavities of the fastening body are expediently open towards the rear. They thus extend from the screwing in the axial direction of the mounting member and are open to the Verschraubungsplatte. This opening or openings may be closed on the side facing away from the screwing plate.
- the fastening body therefore has at least one cavity extending in the axial direction, which is closed by a cover.
- the stiffening structure expediently has ribs. These ribs are advantageously perpendicular to a circumferential wall, and thus radially in the case of a circular cylindrical mounting member. They may also form a triangular or trapezoidal structure so that they are not perpendicular to the wall.
- the ribs are advantageously formed integrally with the lid.
- the depth layer advantageously has a circumferential wall which can be brought into contact with the insulating layer of the ETICS in order to achieve an optimal bond with the thermal barrier coating.
- the peripheral wall can be constructed in a single-layered or multi-layered manner.
- An advantageous embodiment has an inner and an outer wall, wherein the ribs are formed between the two walls. This achieves a simple and stable construction.
- the inner wall in the shape of a cylinder is formed integrally with the lid.
- a screwing plate made of solid material is possible.
- the bolting plate is formed of solid material which is penetrated by a plurality of spaced-apart cavities. These cavities may expand in cross-sectional planes of the prismatic body or perpendicular to it in the direction of its depth. At present, cavities having a longitudinal extent in the direction of the depth of the mounting component are preferred. Such cavities are for example blind holes or Recesses formed in the Verschraubungsplatte. These extend advantageously in the axial direction, which simplifies their production.
- the blind holes can be designed to be either open towards the front side or towards the deep layer. When the front side is closed, this has the advantage that screws to be screwed into it can be attached anywhere.
- These blind holes or recesses have the advantage that the material of the Verschraubungsplatte can cool faster during curing, so that no bubbles form therein and therefore the resistance to tearing out of a screw screwed in there is increased.
- the forces introduced into the assembly component are transferred to the insulating layer in particular via its peripheral surface.
- This creates an excellent connection between the insulating layer and the mounting component the latter is pressed into a smaller by a 2 to 4 millimeters opening.
- the material of the insulating layer is widened, thereby forming a tight fit for the mounting component is formed.
- a profiling of the circumference of the mounting component extending in the direction of the depth can help to achieve an optimum connection between the insulating panel and the mounting component.
- the profiling is formed in a peripheral wall.
- a profiling can be achieved by different wall thicknesses in adjacent areas, it is preferred that the inner surface in the region of the profiling is substantially parallel to the outer surface of this wall. This not only material for this wall can be saved. Consistent wall thicknesses also have the advantage of distortion-free curing and that there is also a profiling on the inside.
- the inwardly directed grooves and combs may cooperate with ribs formed on the lid.
- the screwing plate is designed in two parts. It consists of a first Verschraubungsplatte, which may be designed simply as a lid and is integrally formed on the first end of the hollow, cylindrical attachment body and a second Verschraubungsplatte, which is inserted or inserted into the mounting body and immediately adjacent to the first Verschraubungsplatte.
- a first Verschraubungsplatte which may be designed simply as a lid and is integrally formed on the first end of the hollow, cylindrical attachment body
- a second Verschraubungsplatte which is inserted or inserted into the mounting body and immediately adjacent to the first Verschraubungsplatte.
- the second screwing plate can serve one or more spacers, which are integrally formed on the back cover.
- the second Verschraubungsplatte can also be snapped or clamped. This can be done by providing an appropriate fit.
- the shape of the assembly component is expediently conical at an inner end.
- assembly components 11 have the following common features: It is in each case a straight, prismatic or cylindrical mounting component of a certain depth. This is intended to be arranged within a thermal insulation layer of a thermal insulation composite system and attached to the thermal barrier coating. It is made of a plastic. The embodiments are made of a non-foamed plastic by injection molding. Two layers 13, 15 are formed one after the other in the direction of the depth of the mounting component 11, namely a screwing plate 13 to be arranged externally in the thermal insulation layer and a depth layer 15 adjoining this screwing plate 13, which is also referred to as a fastening body.
- the depth layer 15 is constructed much lighter weight than the Verschraubungsplatte 13. The weight of the layers is through determines the void fraction and the solid wall fraction. The solid wall portion of the depth layer 15 is less than the solid wall portion of the screw 13.
- a peripheral wall 19 is provided, which forms the jacket of the fastening body 15. Except for the embodiment according to FIG. 1 is the fastening body 15 by stiffening walls 21, respectively. Ridges 35 stiffened within the mounting body 15. Also in all embodiments, the Verschraubungsplatte 13 is provided with cavities in the form of blind holes 27. All illustrated assembly components 11, except the embodiment according to FIG. 4 , are formed circular cylindrical. This training is advantageous because a circular cylindrical hole for rich reception of the mounting member 11 can be very easily and precisely introduced into the thermal barrier coating. Nevertheless, cuboid mounting components are according to the FIG. 4 or those with polygonal base possible. These cuboid mounting components preferably have rounded corners, so that a recess for such a mounting component can be milled with a milling tool. The corner radius of the mounting component corresponds to half the diameter of the milling head.
- the mounting member 11 For the maintenance of the mounting member 11 in the insulating material of the thermal barrier coating, especially that surface of the mounting member 11 is responsible, which extends parallel to the depth and the extension direction, or perpendicular to the end face 17.
- This surface is provided in the region of the fastening body 15 by the outer surface 25 of the peripheral wall 19 and in the region of the screwing plate 13 by its circumferential surface 23.
- An assembly component according to the invention can be cast in one piece, as in the exemplary embodiment FIGS. 1, 2 and 4 the case is. But it can too be composed of a main part 29 comprising the Verschraubplatte and the fastening body and an insert 31, as shown in the other embodiments.
- An advantage of a two-part design is that the cavity of the mounting component can be closed.
- a one-piece design has the advantage that only one mold for the production of the assembly component is needed.
- the blind holes 27 serve to cool the Verschraubungsplatte13 during the setting of the plastic immediately after the injection process. With the cooling is achieved that during the curing of the plastic no bubbles are formed therein. As a result, a higher strength of the product is achieved.
- the blind holes 27 can basically be closed or open on the end face 17. In the embodiment according to FIG. 1 the end face 17 is perforated. This has the disadvantage over the embodiments according to FIGS. 2 to 12 with a closed face, that screws can practically only be screwed into a given hole. In the closed end face 17, however, a screw can be screwed at any point in the Verschraubplatte.
- the cover layer between the end face 17 and the bottom of the blind holes 27 is sufficient to give the screw sufficient direction that it can be screwed into the end face 17 with sufficient accuracy, even if it partially extends in a blind hole and partially in the full material.
- the stiffening walls 21 may in a two-piece mounting member 11 on the insert 31 ( Figures 3 . 10.12 ) or be formed on the fastening body.
- the insertion part 31 may comprise only the stiffening walls and no lid. If a cover is provided, then it can be accommodated inside the peripheral wall 19 (see exemplary embodiments according to FIGS Figures 3 . 9 and 10 ) or externally flush with the peripheral wall 19 may be arranged (see embodiments according to the FIGS. 11 and 12 ).
- the lid is preferably firmly connected to the fastening body.
- FIGS. 5 to 12 show two embodiments in which the peripheral wall 19 is structured. In the embodiments according to FIGS. 1 to 4 however, the outer surface 25 of the peripheral wall 19 is smooth.
- the preferred embodiments according to FIGS. 5 to 12 have a main part 29 whose end face 17 is formed circular and closed with a smooth or rough surface.
- a mounting component for example of the nominal size 70 mm
- the outer surface of the mounting member 11 is already provided with grooves.
- the groove 33 is formed by a wall profile extending in a zigzag cross section.
- the body which is largely full, is bordered by a peripherally grooved circumferential surface 23.
- Mounting components with other nominal sizes, for example 65, 90.125mm have correspondingly greater or lesser mass.
- the scoring is also manifest. In these grooves extend into 1.5 mm thick ribs 35 of the stiffening wall 21.
- the stiffening wall 21 has a circular cylindrical wall on the outside of which these ribs 35 protrude perpendicular to the surface and extending parallel to the axis of the circular cylindrical wall.
- the 50 mm deep depth layer 15 ends in a conical end region. This conical end serves to allow the mounting member 11 can be better inserted into a bore having a smaller diameter than the outer diameter of the mounting component measures. For the strength of the depth layer 15, half of the 24 ribs 35 shown would suffice.
- the blind holes 27 in the Verschraubungsplatte 13 are formed from the inside of the mounting component forth and from its base to the opening conically widening.
- the blind holes are 17 mm deep in the 20 mm thick screw 13 formed in it. They have a diameter of 3 to 3.5 mm.
- the material thickness between the blind holes is at the thinnest points about half as thick as the diameter of the blind holes.
- a label 37 of the mounting component available on the rough end face 17 .
- the roughness serves for a better connection between the component and the plaster layer built up on the thermal barrier coating.
- FIGS. 9 and 10 or 11 and 12 illustrated embodiments differ only in the separation between the insertion part 31 and the main part 29.
- the insertion part 31 is completely disposed within the peripheral wall 19, so that the conical end portion of the depth layer 15 is formed entirely by the peripheral wall.
- the conical end region of the depth layer 15 is formed on the insertion part 31.
- the separating seam between the insertion part 31 and the peripheral wall 19 is at the transition from the cylindrical to the conical region of the depth layer 15th
- the mounting component is mounted as follows. A hole with a diameter of preferably 71 mm and a diameter of preferably 68 mm is drilled in the finished thermal insulation layer made of EPS using a special drill. An adhesive is now painted into this hole and the assembly component with the conical end region is inserted into the drilled hole. The pressing in of the assembly component must be applied pressure, because the hole has to be widened. However, this has the advantage that the mounting component is anchored positively and under bias in the insulation board. After the PU adhesive has hardened, an adequate resistance to tearing is achieved with an EPS thermal barrier coating of a specific weight of 15 kg / m3. This allows the application of 60 kg tensile load to the mounting component, without this would be torn out. The pull-out load which the screw can tear out of the screwing plate is considerably higher.
- the Verschraubplatte has a minimum thickness of 5 mm, preferably 10 mm and most preferably 15 mm.
- the mounting member 11 has a minimum depth of 50 mm, preferably 60 mm and most preferably 70 mm. There are different nominal widths of the mounting component can be realized.
- the maximum installation depth of the mounting component is less than 100 mm, preferably less than 90 mm and most preferably less than 70 mm.
- a preferred embodiment has a circular cylindrical mounting body 15, whose one end is closed with a bottom 13 which forms the screwing.
- This bottom 13 may be equipped with cavity-oriented blind holes, but not necessarily. This depends inter alia on the strength with which the cover 13 is formed.
- the actual Verschraubungsplatte is a separate component 41, which is inserted into the cavity of the mounting body 15.
- This Verschraubungsplatte 41 advantageously has a thickness of at least 5 mm, preferably a thickness between 5 and 20 mm and more preferably between 6 and 18 mm.
- the screwing plate 41 is with a plurality of holes 43 perforated to save weight and to accelerate the cooling process in the production of the injection molded part.
- any known in the art thermoplastic can be used. In particular, recycled plastics made of PET, PP or phenolic resins are also possible.
- the Verschraubungsplatte 41 is held by spacers 45 which are arranged or formed on the lid 47, immediately adjacent to the lid 47.
- the spacers 45 are radially extending webs 47, which are integrally formed on the inside of the lid. In the middle of a hollow cylinder 49 is provided on the inside of the lid, from which the webs 47 extend radially outwardly.
- the webs 47 additionally have the function of ensuring the dimensional stability of the fastening body 13.
- the cover 47 itself is connected to the fastening body 13 by means of gluing, welding, extrusion coating or by a snap connection, etc.
- undercuts can be provided on the side edges of at least two webs, which can engage in corresponding recesses on the inside of the peripheral wall of the fastening body (not shown in the figures).
- Other configurations for a snap connection are also possible and known to those skilled in the art.
- the mounting component according to the invention is used as follows: First, a hole is drilled out in a preferably foamed insulation board, eg EPS, with a drill, the depth of which permits a flush insertion of the mounting component in the insulation board. Since the insulation boards are usually at least 100 mm thick, there is still an insulating layer between the mounting component and the supporting component. The diameter of the hole is drilled 2 to 3 mm smaller than the outer diameter of the mounting component. Then, the mounting member is pressed into the hole, where - depending on the purpose - still an adhesive can be used. The assembly takes place anchor-free, in order to avoid thermal bridges. It is conceivable, the cavity of the mounting component foam later. For this purpose, an opening is provided in the Verschraubungsplatte through which the plastic can be injected.
- a hole is drilled out in a preferably foamed insulation board, eg EPS, with a drill, the depth of which permits a flush insertion of the mounting component in the insulation board. Since the insulation boards are
- the invention can be summarized as a straight, quasi prismatic or cylindrical mounting member 11 will be described.
- quasi-prismatic is meant a very steep truncated cone or truncated pyramid, the deviation from the vertical being less than 2 degrees and preferably less than 1 degree.
- the slightly conical shape is used for better demoldability of the mounting member 11 and the improved fit in the thermal barrier coating. This is suitable for arrangement within and attachment to a thermal barrier coating of a thermal insulation composite system.
- the formed of a plastic mounting member 11 is formed with a sequence of two layers 13,15, namely an externally arranged Verschraubungsplatte 13 and an adjoining, deeper into the thermal barrier layer to be arranged depth layer 15. In the end face 17 of the screw are screws can be screwed.
- the deep layer 15 has both a cavity portion and a solid wall portion, wherein the solid wall portion of the depth layer 15 is less than a solid wall portion of the screw 13.
