Description

The invention relates to a gluing body for gluing a lightweight board with a material body, a method for gluing at least one lightweight board with a material body and a material body connection for connecting a lightweight board with a material body.

For lightweight panels with outer layers and a middle layer, especially in lightweight panels, where at least the outer layers are wooden materials, there are major problems the lightweight panels with each other or with other materials, especially plate materials to connect economically. The reason for this is the middle layer, which usually does not have sufficient strength. Although the cover layers form flat surfaces, but they also have too low strengths to attach conventional fasteners and fittings to them. Thus, for example, common round dowels or flat dowels for connecting two plates can not be used because they do not find sufficient support in the lightweight board.

In the large industrial sector, that is, in the mass production of furniture, these problems are solved by massive depositors, which are placed in the production of lightweight board exactly in the areas in which later fittings or fasteners to be incorporated. However, this is only possible if their subsequent use is already known in the manufacture of the plates. In the manual production of furniture, in which standard plates are individually tailored to the respective required component size, a production-side reinforcement of the plates is accordingly not possible. In this case, recesses for inserts would have to be subsequently produced and the inserts glued in place.

The industrial introduction of inserts also takes place mainly in lightweight panels with thicknesses of more than 20 mm, since due to the deposit increases the weight of the lightweight panels and thinner panels, the weight advantage is too low. Thus, straight plates in the thickness range between 10 mm to 20 mm are rarely designed as lightweight panels. However, straight plates of these strengths are used, for example, in furniture for cabinets whose carcass parts, shelves, doors, etc. both in the craft and in the industry prioritized.

Alternatively, there are special lightweight panel connectors and lightweight panel fittings, but their uses are each very limited, which bring a high installation cost, are expensive and for their installation mostly special tools are necessary.

The invention has for its object to provide a device, a method and a corresponding material connection can be easily glued together with the lightweight panels.

The invention solves the problem by a Verleimkörper with the features of claim 1, a Verleimkörper with the features of claim 15, a method having the features of claim 16 and a material body connection with the features of claim 21. In this case, all the features described are themselves or in any combination, in principle subject of the invention, regardless of their summary in the claims or the relationships.

The glueing body according to the invention for gluing a lightweight board with a material body, wherein the lightweight board has at least one middle layer arranged between two cover layers, is integrally formed and comprises at least two gluing sections, wherein a first gluing section for gluing with both cover layers of the lightweight board and a second gluing section for gluing the material body are formed.

About the two gluing and the integral formation of the gluing, it is possible in a particularly simple manner to glue a lightweight board with another material body. In this case, the gluing allows to make an exclusive adhesive connection between the lightweight panel and the material body, without further separate connection means, such as screws, fittings or the like. In addition, the gluing body allows individually tailored lightweight panels to be glued to other material bodies via an adhesive connection, without the need for elaborate inserts, special fittings or the like to be incorporated into the lightweight panel. Finally, the gluing also allows thin lightweight panels, i. In particular lightweight panels with a thickness between 20 mm and 10 mm in a simple way to bond with other material bodies.

The integral nature of the glued body simplifies assembly and ensures a secure connection between the lightweight panel and the material body. By one piece is meant that the glue body is a component that can not be disassembled nondestructive.

Advantageously, the gluing of solid wood, a fiber material, in particular a HDF or MDF, a chip material, a plastic or a wood-plastic composite (WPC). So he can, for example, according to the known Lamello flat dowels made of pressed and embossed beech wood. Alternatively, the gluing body, for example, also consist of a metal or a combination of two or more of the aforementioned materials.

The lightweight board has two cover layers, which are fixedly connected to the central layer and not destructively separable. The cover layers are advantageously made of a wood material. For example, the cover layers may be formed of chipboard, fiberboard, in particular MDF or HDF, veneer wood panel, veneer, plywood panel, blockboard or a wood-plastic composite panel.

The middle layer advantageously has a lower specific weight compared to the cover layers. The middle layer may be, for example, a foam core, a honeycomb panel of paper / cardboard / plastic / wood material, a wood-based panel with low specific weight o. Ä. Be. Also, the middle layer may be formed multi-layered. Thus, the middle layer, for example, consist of a combination of the aforementioned materials.

In principle, the gluing body is suitable for gluing (gluing) with all the adhesives customary in the field of wood-based material processing. Thus, for example, the gluing body can be glued to the lightweight building board by means of white glue or other one-component or multicomponent dispersion or solvent adhesives, one-component, two-component or multicomponent reaction adhesives, hot melt adhesives, and also reactive hotmelt adhesives and other adhesives. The adhesive body may also be precoated with adhesives in such a way that the adhesive force is increased by the addition of water or a solvent or a hardener component or by the action of energy such as, for example, light waves or ultrasound. Like. Is activated before or during the joining process.

Under a material body components of different types can be understood. For example, these may be furniture elements such as studs, legs, arms or the like. Advantageously, the material bodies are also plates, in particular wood-based panels, such as. Fiber boards (MDF, HDF, etc.), chipboard, OSB boards, blockboard, plywood boards. These can be solid materials. The material bodies can also be lightweight materials, for example lightweight building panels. Lightweight panels designed as a material body advantageously also have a centerage arranged between two cover layers.

The shape of the gluing bodies can be designed differently. In the horizontal cross section (for example, by the two gluing sections), it preferably has an almond-shaped form adapted to the known Lamello dowel shape. Almond-shaped is understood to mean an oval shape consisting of two identical intersecting circular arcs, the intersections being rounded. The size (external dimensions) of the glueing body, in particular the length, width and optionally the thickness of the gluing sections can be adapted to the known dimensions of the Lamello dowels. Particularly advantageous is the adaptation of the circular arcs to a radius of 100 mm, which corresponds to the usual cutting radius of Lamellodübeln.

If a complete almond shape is not present, advantageously at least the first or second gluing section is adapted to the known Lamello dowel shape and has a semi-almond-shaped cross-section (horizontal section). Untermandelförmig is understood to mean an almond shape divided on the longitudinal axis. This ensures that existing, designed for Lamello dowel milling tools can be used particularly easily when using the glueing body.

However, especially the gluing sections can also be adapted in their shape. Thus, the gluing body and / or the gluing sections in the horizontal cross section may also have, for example, a largely angular, for example a rectangular shape.

By means of the gluing body, abutting edge connections between a lightweight board and a material body can be produced. For the same material thickness, these can, for example, be made flush with the surface. In addition, corner connections or T-connections between the lightweight board and the material body can be made. It should be noted that the gluing body with its first gluing section is always glued to both covering layers of the lightweight building board and its second gluing section to the material body.

If the material body is also a lightweight board, the second gluing section is preferably also adhesively bonded to both outer layers of the material body both in the case of a butt joint and in the case of a corner or T joint.

According to a development of the invention, the glueing body has a stepped cross section in the vertical cross section (along the width of the glueing body). In other words, in the vertical cross section through the two gluing sections, steps / shoulders are present across the entire width of the gluing body. Under stepped cross sections are also To understand in vertical cross section representing recesses or grooves with shoulders / corners. It should be noted that in the stages / paragraphs, the respective middle levels of the individual sections stage / paragraphs have. For example, surface embossing is not considered as steps / heels.

Particularly preferably, the gluing sections have a different thickness, wherein a step is arranged between the gluing sections. In this case, the first gluing section is adapted to the thickness of the middle layer of the lightweight board, if necessary supplemented by the height of recesses produced on the insides.

Particularly preferably, the first gluing section has two gluing surfaces, which are arranged parallel to one another and are designed for gluing with one of the cover layers in each case. Accordingly, the distance between the gluing surfaces to be glued to the cover layers is, for example, equal to the thickness of the middle layer.

For particularly good gluing of the gluing body with the lightweight board, however, recesses are produced in the region of the insides of the cover layers, for example with a milling tool, so that the distance between the gluing surfaces at the first gluing section corresponds to the spacing of the surfaces of the recesses at the two cover layers.

The thickness of the first gluing section is dependent on the thickness of the respective lightweight board, the thickness of the cover layers and whether the recess is produced flush with the inner surface of the cover layers or whether the recesses in the cover layers and, if necessary, at what depth (thickness: Y). Direction) intervene. In this case, the engagement depth (or the remaining overlap) is preferably approximately ½ of the cover layer thickness. For lightweight panels with cover thicknesses between 3 mm and 4 mm, the depth of engagement may be, for example, 1 mm, 1.5 mm or 2 mm, i. preferably between 1 mm to 2 mm.

For lightweight panels having a thickness between 10 mm and 20 mm, the thickness of the first gluing portion of the gluing body is advantageously between 4 mm to 18 mm, preferably between 4.5 mm to 18 mm, particularly preferably between 5 mm to 18 mm, preferably between 11 mm up to 17 and advantageously between 15 mm to 16 mm, each with a tolerance of approx. + 0.2 / -0.2 mm. Thus, for example, in a 19 mm thick lightweight board first gluing of the Verleimkörpers between 11 mm to 16 mm and preferably between 13 mm and 15 mm, for example, 14 mm are particularly suitable.

The thickness of the second gluing section can be designed accordingly, but is preferably 4 mm +/- 0.3 mm or maximum 8 mm +/- 0.3 mm maximum, so the usual strength of flat almond-shaped Lamellodübeln. As a result, the known devices for milling the recesses for the flat Lamello dowels can also be used in the Verleimkörpern invention.

A step is understood to mean a step on which an edge is formed. The step has a step surface. Particularly preferably, the step surface is arranged at an angle of 90 ° +/- 1 to 2 ° or 45 ° +/- 1 ° to 2 ° to the gluing surface of the first gluing section.

According to a development of the invention, the second gluing section is arranged in the vertical direction between the gluing surfaces of the first gluing section, preferably centrally, more preferably at a distance ratio of ¼ to ¾ or in alignment with one of the gluing surfaces of the first gluing section. The second gluing section protrudes, for example, out of a step surface, i. extends in the parallel direction of the gluing surfaces of the first gluing section.

The strength of the first gluing section is adapted to the thickness of the lightweight board. For example, the first gluing section can consist of a solid component section which extends beyond the respective thickness of the gluing body. According to a development of the invention, the first gluing section has two lamellae, which are arranged correspondingly spaced and which each have a gluing surface for gluing each with one of the cover layers of the lightweight building board.

The lamellae of the first gluing section can have a thickness of approximately 4 mm +/- 0.3 mm, which is adapted to the known Lamello dowels, which in turn allows the known milling tools to be used during assembly.

The second gluing section can be formed, in particular in the case of the formation of the material body, as a lightweight board in accordance with the first gluing section. Particularly preferably, the second gluing section is plate-shaped (for example designed as a plate-shaped lamella) and has a thickness of 4 mm +/- 0.3 mm maximum or a thickness of 8 mm +/- max 0.3 mm.

Particularly preferably, the second gluing section can also comprise two, for example, parallel slats.

According to a development of the invention, the glueing body has a third and / or fourth Gluing on, wherein the third and / or fourth gluing section is designed for gluing with two cover layers of a lightweight board or for gluing with a material body.

By means of a Verleimkörpers with three Verleimabschnitten example, a T-shaped connection of three components (lightweight panels and / or material bodies) are made, which are mitered in the connection area. Accordingly, a cross-shaped connection of four components (lightweight panels and / or material bodies) can be produced with a Verleimkörper with four gluing sections, which are mitered in the connection area.

As already stated, the gluing body may, for example, have an almond-shaped cross section. According to a further preferred embodiment, the gluing body is strip-shaped. In this case, the glueing body has a first gluing section, which is glued with both cover layers, but is particularly narrow and has a particularly long length. The strip-shaped glueing body can be designed as an insert-milled spring and can be designed in the range of a few millimeters (eg 2 mm to 10 mm, without the width of the second gluing section) so that it has only a small depth of extension into the lightweight board (the height the strip-shaped glue body extends in the direction of the lightweight board thickness).

However, the strip-shaped gluing body, for example, extends over the entire length (at least for the most part over the entire length) of a side edge of the lightweight building panel or may be exposed to the end areas. The strip-shaped adhesive body thus has a preferred width-to-length ratio of at least 1:20, preferably 1:50 or 1: 100 or more.

The second gluing section protrudes out of a step surface in the form of a spring and also has only a small width (for example in the range from 2 mm to 10 mm, preferably up to, for example, the deck thickness or the ½ deck thickness into which the spring extends). on. The mounted second gluing section thus extends, for example, only in a few mm deep groove in the material body.

According to a development of the invention, the glueing body has an almond-shaped form in the horizontal cross section. Regardless of the shape, the sizing body may be, for example, about 47 mm long and 17 mm wide or about 62 mm long and 27 mm wide or about 70 mm long and 34 mm wide. Length and width are advantageously in a ratio between 1: 2 to about 1: 3.

Regardless of the shape, length and width of the gluing body, the thickness and length of the gluing body are preferably in a ratio between 1: 1 to 1:10, more preferably between 1: 1 to 1: 8, advantageously between 1: 1 to 1: 5 and preferably between 1: 2 and 1: 4. In other words, the glueing body has a dowel-like construction and can thus be designed as a localized fastening means, so that a plurality of gluing bodies can usually be arranged next to one another over the sections of the lightweight building panel to be glued.

According to a development of the invention, the first gluing section and the second gluing section each have a gluing surface which is at an angle of 25 ° + / 5 ° to 175 ° +/- 5 °, in particular at an angle of 90 ° +/- 5 ° are aligned to 10 ° to each other. Such Verleimkörper allow the particularly simple production of angular Gehrungseckverbindungen.

To produce flat abutting edge connections, the first gluing section and the second gluing section each particularly preferably have a gluing surface which is aligned in alignment with one another. That is, the two gluing surfaces have an angle of 180 ° to each other.

For particularly strong connections of lightweight panels with material bodies is also provided that a bonding body is integrally formed with a cover layer and / or a middle layer of the lightweight board in which, for example, a solid material portion is arranged and has a second Verleimabschnitt for gluing with a material body. The formation of the second Verleimabschnitts can be carried out according to the above-described embodiments. As a result, the forces are transmitted particularly simple and effective in the cover layer, so that particularly secure connections can be produced.

• • Erstellen einer auf die Form eines ersten Verleimabschnitts eines Verleimkörpers angepassten ersten Ausnehmung in der Mittellage der Leichtbauplatte, wobei die Ausnehmung an beide Deckschichten angrenzt oder zumindest in einer der Deckschichten zumindest teilweise angeordnet ist;
• • Erstellen einer auf die Form eines zweiten Verleimabschnitts des Verleimkörpers angepassten Ausnehmung in dem Werkstoffkörper;
• • Einführen eines ersten Verleimabschnitts des Verleimkörpers in die erste Ausnehmung und Verleimen des Verleimkörpers mit beiden Deckschichten;
• • Einführen eines zweiten Verleimabschnitts des Verleimkörpers in die zweite Ausnehmung und befestigen, insbesondere Verleimen des zweiten Verleimabschnitts mit dem Werkstoffkörper,

Furthermore, the object of the invention is achieved by a method for bonding at least one lightweight building panel to a material body, wherein the lightweight building panel has at least one middle layer arranged between two cover layers, with the following steps:

• Creating a first recess, which is adapted to the shape of a first gluing section of a gluing body, in the middle position of the lightweight building board, wherein the recess adjoins both cover layers or is at least partially arranged in at least one of the cover layers;
• Creating a recess in the material body adapted to the shape of a second gluing portion of the gluing body;
• Inserting a first gluing section of the gluing body into the first recess and gluing the gluing body to both covering layers;
• Inserting a second gluing section of the glueing body into the second cutout and fastening, in particular gluing the second gluing section to the material body,

The method according to the invention makes it possible to glue lightweight panels with a middle layer arranged between two cover layers with a workpiece or also lightweight panels in a particularly simple manner, without the need for complicated inserts or special fittings for connecting the individual lightweight panels to the lightweight panel.

Thus, the method also allows to glue individually tailored lightweight panels with material bodies or with lightweight panels.

By creating a recess in the lightweight building board, which is aligned with the shape of a first gluing section, it is understood that starting from the side edge of the lightweight building board, a recess is made in the lightweight building board. The introduction of this recess takes place, for example, by means of a milling or sawing tool and can be done, for example, by means of a Lamellofräswerkzeuges, provided that the gluing is aligned according to the size of the known flat Lamellodübel. The recess can either in one step, d. H. with, for example, a wide milling disc, which is inserted into the side of the lightweight board produced.

However, the recess can preferably also be made in such a way that, for example, two partial recesses, one per cover layer, are produced by means of a multi-disc milling tool, wherein each partial recess adjoins or projects into the inside of one of the cover layers. Thus, for example, it is possible to make two millings with a lamella milling tool, each starting from the outer surface of each cover layer, so that two opposite partial recesses are arranged in each cover layer in the lightweight building board. The two partial recesses form the recess. The vertical spacing of the surfaces of the partial recesses is adapted to the thickness of the gluing body and here to the first gluing section.

According to the first recess and the second recess can be arranged in the material body, if this is also a lightweight board.

For a solid material, d. H. For example, a plate made of solid material, a corresponding groove or recess is introduced according to the shape of the second Verleimabschnitts. If the second gluing section is, for example, half-mandrel-shaped adapted to the shape of a half Lamellodübels, is particularly easily formed by means of a Lamellofräswerkzeuges a slot either on an outer side of the material body or in an end face of the material body, for example. Milled or drilled.

When inserting the first gluing section, for example, the middle layer of the lightweight building board with the gluing body is pushed away, insofar as it is a movable center layer. For example, this is possible with middle layers made of a honeycomb material made of cardboard or paper. If the recess was milled out as a whole, the first gluing section can be inserted into the recess particularly easily.

Before insertion, the adhesive (the glue) is applied either in the area of the recess and / or on the first gluing section. Due to the matching of the recess to the first gluing section, the first gluing section is glued with both cover layers and in particular here with the surfaces of the recesses in the respective insides of the cover layers. Before inserting the second gluing section into the second recess (of the material body), either the second gluing section and / or the second recess is likewise wetted with glue. Subsequently, the second gluing section is inserted into the second recess and also glued with this.

If the material body is also a lightweight board and by means of the lightweight board and the material body (the second lightweight board) a T-shaped connection or a corner joint to be made, it is introduced so deep in the plate in the direction of plate thickness in the production of the second recess, that the recess adjoins the surface of the inside of the covering layer opposite the gluing body or, if necessary, extends even into it through it. Accordingly, glue is also applied to the inside of the opposite cover layer or in the groove now present when the glue is applied, or the second glue section is wetted with glue in such a way that a glue connection is formed between the second glue section and the opposite cover layer.

In a preferred embodiment, the gluing body has, between the first gluing section and the second gluing section, a step which has a step surface. In such a Verleimkörper is after a development of Invention, the step surface of the Verleimkörpers flush with a side edge or a surface of the lightweight material. As a result, a particularly secure system of the material body is ensured on the lightweight board.

In order to further improve the connection between the lightweight board and the material body, the step surface of the glueing body is glued to a surface of the material body, in particular to an outer side or a side edge. As a result, the adhesive surface between the lightweight board and the material body is significantly increased, so that the material body connection has a significantly increased strength.

According to a development of the invention, the material body is a second lightweight material with at least one middle layer arranged between two cover layers, which may in particular also be designed as a lightweight board, so that the second gluing section is glued to both cover layers of the material body.

This is done both in a gluing of the side edges and a side edge of the lightweight board with a surface of the material body. By gluing the second Verleimabschnitts with two outer layers of the material body a particularly secure and stable connection is made and the forces occurring on the compound are reliably transmitted both to the two outer layers of the lightweight board and on the two outer layers of the material now formed here as lightweight board ,

The invention is further achieved by a material connection for connecting a lightweight board to a material body, the lightweight board having a middle layer arranged between two cover layers, an integral Verleimkörper is arranged, the at least two Verleimabschnitte, a first and a second Verleimabschnitt, the Verleimkörper with the first gluing section is glued to the two cover layers of the lightweight material and the second gluing section is arranged and fastened in a recess of the material body.

The material body connection has already been extensively described in connection with the Verleimkörper and the method. It should be noted that the recess can, for example, completely penetrate the material body and, for example, the second gluing section protrudes through the material body and is fastened exclusively to the material body. This can be used, for example, as a special decorative element. The second gluing section can accordingly be wedged, for example, on the section protruding from the material body with the material body. The gluing section can, for example, also have a harpoon web profile, so that the second gluing section can not be pulled out of the material body. Finally, it is of course also possible to glue the second gluing section to the second material body.

The material body connection according to the invention thus allows, as already stated, a particularly simple connection of a lightweight board with a further material body, which may also be formed as a lightweight material, for example. Lightweight panel, or even of a solid material, in particular a wood material.

Particularly preferably, the gluing body has a stepped cross section and the gluing body is in particular formed with a different thickness and / or a step between the gluing sections. Due to the stepped embodiment, both lightweight panels with lightweight panels and lightweight panels with solid material can be particularly easily glued together. This can be done in particular with known tools, such as. A router for Lamellodübel.

In addition to the gluing of the first or second gluing section with the lightweight building panel or the material body, according to a development of the invention, a step surface of the gluing body is glued to a surface, in particular a surface or a side edge of the material body. As a result, the material body connection is made much stronger and can absorb significantly higher forces.

The surface sections designed to be glued to the cover layers of the lightweight building board are particularly preferably arranged parallel to one another. As a result, a particularly secure and durable gluing of the glued body is ensured with the two outer layers of the lightweight board.

According to a development of the invention, it is further provided that the material body connection between the lightweight board and the material body is an angular connection ≠ 180 °, wherein the second gluing section protrudes through a cover layer and a middle layer of a material body designed as a lightweight board, possibly up to a second cover layer of the material body and is glued to both outer layers of the material body.

The attachment of the second Verleimabschnitts to the material body may, for example, in addition to the aforementioned wedging over a mechanical connection means, such as, for example, a screw, done. Particularly preferred, however, is formed exclusively between the material body and the lightweight panel an adhesive bond, in particular between the first gluing and the lightweight panel and / or between the second gluing and the material body is an adhesive bond. The adhesive bond with the previously created recesses allows a particularly precise assembly of the lightweight board with the material body and takes all the advantages of the already known Lamellodübelverbindungen.

In particular, for the formation of a corner joint or a Gehrungseckverbindung is provided according to a development of the invention that the second gluing at an angle α ≠ 180 °, in particular at an angle α = 25 ° - 175 °, preferably at an angle α = 90 ° ± 1-2 ° aligned to the cover layers is arranged.
