Description

The invention relates to a vehicle with a repaired sandwich panel according to the preamble of claim 1, as well as a repair kit for repairing a sandwich panel according to the preamble of claim 10.

Sandwich panels are lightweight composite materials usually made of an insulating layer enclosed between two outer layers, which are used in particular for vehicle cladding of mobile homes or caravans. Sandwich panels are difficult to repair due to their structure. In the case of caravan bodies, for example, side walls made of a sandwich panel are always completely replaced, even if there is minor damage.

From the US 2010 161 095 A it is known to separate out a damaged area of a sandwich panel and to replace it with a replacement part, the replacement part being able to be connected to the sandwich panel, for example, via an external patch.

The object of the invention is to be able to repair sandwich panels, in particular sandwich panels of mobile homes or caravans, simply and inexpensively in a few work steps. Another task is that the repaired sandwich panel cannot be recognized as such, that is to say, in particular, that it has no visual impairment. In another aspect, the object of the invention is to provide a repair kit suitable for carrying out a repair.

These objects are achieved by a vehicle with the features according to claim 1 and a repair kit with the features according to claim 10. Advantageous embodiments and further preferred features of the invention emerge from the subclaims.

A vehicle mentioned at the beginning is characterized according to the invention in that the reinforcing element or elements are arranged on the sides of the outer skins facing the insulating layer. Only the first or only the second or both outer skins of the sandwich and replacement panels can each be connected to a reinforcing element.

The reinforcing element can be a profile-like or hollow profile-like body with, for example, a cuboid cross-section.

The replacement panel has the same structure as the original, damaged sandwich panel. Unless otherwise stated, the term sandwich panel always refers to the original sandwich panel below.

Through the use of internal reinforcement elements, the total thickness of the repaired sandwich panel remains constant. A visual impairment of the connection point can also be avoided.

The outer skin and the reinforcing element can advantageously be connected to one another by means of an adhesive, preferably in a materially bonded manner. During processing, an adhesive offers the possibility of joining individual components immediately after applying the adhesive or later within the pot life of the adhesive, or of subsequently adjusting the position of components that have already been joined. This gives a high degree of flexibility in the manufacture of the connection. By choosing an adhesive, processing and curing times can also be set in a technically advantageous manner. The curing of the adhesive can also be influenced and in particular accelerated by heat treatment or irradiation, for example with UV light. For example, a one-component adhesive or two-component adhesive, e.g. made of silicone-free epoxy resin or a commercially available car body adhesive, is used as the adhesive. The adhesive can preferably be painted in order to make the transition “invisible” after the replacement panel has been joined and glued to the sandwich panel.

Preferably, the replacement panel to form a joint between the replacement panel and the sandwich panel can be smaller than the repair section of the sandwich panel, in particular sufficiently small that a joint exists between the replacement panel and the sandwich panel, in particular between their outer skins, i.e. the panels are not butted together. The joint is e.g. 1 mm wide. The joint width is advantageously no greater than 3 mm, preferably no greater than 2 mm. With a large joint width, the replacement panel can be easily inserted into the repair section. Compared to a butt joint connection between sandwich panel and replacement panel, this also prevents the overcoating of the joint from cracking or piling up due to temperature-related different expansions of sandwich panel and replacement panel.

The joint between the outer skins of the replacement and sandwich panels can preferably be filled with the same adhesive connecting the outer skins and the reinforcing element. The filling can take place during the joining process of the panels themselves. Adhesive jointing means that separate jointing can be omitted and one work step can be saved.

In a preferred embodiment, the replacement panel can have at least one joining section and at least one edge section, the replacement panel being connected to the sandwich panel only via the joining section. This allows joining at the edge, wherein the reinforcing element can be connected to the sandwich panel or the replacement panel before joining.

A clearance for receiving a reinforcing element can advantageously be formed in the insulating layer of the sandwich panel and / or the replacement panel. The exposure can advantageously touch at least one outer skin. However, the exemption can also touch both outer skins. Several clearances can also be made in the insulation layer of the sandwich panel and / or the replacement panel. A clear and full-surface gluing of the reinforcing element and the outer skin can be achieved, since a sufficient amount of adhesive can be applied to the clearing before the reinforcing element is inserted into the clearing and / or by the reinforcing element in the clearing without touching the outer skin or an insulating layer introduced and connected to the outer skin by means of a movement directed perpendicular to the outer skin. This avoids the risk of a quantity of adhesive applied to the reinforcement element being removed from the outer skin or the insulation layer, e.g. on an outer skin edge, when connecting to the outer skin.

The cross section of the clearance can be rectangular, for example, with the longer edge of the rectangle running along the plane of the outer skin. However, it can also be shaped differently. The exposure can have a sufficient depth in the surface directions of the outer skin or insulation layer, so that even large, in particular large-area stiffening elements can be introduced into the exposure. In this way, depending on the load profile, a smaller or larger reinforcing element can be used. In other cases, for example, support structures running in or through the sandwich panel, such as wooden beams or GRP hollow profiles, on which, for example, internal erection is suspended, can be replaced or supplemented.

The reinforcing element can advantageously be designed in the form of strips or plates. As a result, reinforcement elements can be produced easily from reinforcement element blanks. In particular, individual lengths and shapes can be created. A strip or plate thickness can in particular be 2 or 3 mm. A joint area between the reinforcement element and sandwich panel and / or replacement panel is about 2 to 8 cm wide for sufficient adhesion, so that the total width of a reinforcing element is about 4 to 16 cm (optionally plus a joint width).

The reinforcing element can advantageously consist of a plastic, in particular a glass fiber reinforced plastic. Glass fiber reinforced plastic is inexpensive and available in sheet form in many thicknesses even in small quantities.

For the indirect connection of two outer skins of the replacement and sandwich panels, several reinforcing elements spaced apart from one another can advantageously be used. As a result, the processing of a large number of reinforcing elements can be simplified compared to a single reinforcing element, particularly in the case of long joining sections. Furthermore, expansion joints e.g. for thermal expansion or the escape of superfluous adhesive from e.g. adhesive-filled clearances can easily be made possible. The passage through support structures running through the sandwich panel, such as wooden beams or GRP hollow profiles, on which, for example, is suspended from the inside, is also possible. A favorable length of reinforcement elements is 30 cm or less. A favorable distance between reinforcement elements is 1 cm or more.

In 1A is a vehicle 1000 shown in the form of a mobile home in a side view, its driver (obviously frightened) after repairing a first damaged area S. in repair section R. further damaged areas S1 to S3 in the sandwich panels designed as vehicle planking. The sandwich panels form the side walls and ceiling of the living space of the motorhome.

The following is an example of the sandwich panel 10 the left side wall is referred to. The sandwich panel 10 is made up of three layers, for example from 2 a) results in and has a first outer skin 10a , a second outer skin 10c and an insulating layer in between 10b on. With the outer skin 10a or 10c This is a glass fiber reinforced plastic sheet with a thickness of about 2mm. However, it could also be cladding made of a metal such as aluminum or steel or another material such as wood or wood composite. The insulation layer 10b is formed here from an open-pored plastic foam. However, it could also be a closed-cell plastic, a honeycomb structure or the like. Materials such as EPS, XPS, or materials commonly used under brand names such as Styrodur or Styrofoam are conceivable. RTM or PU foams or other heat and / or sound insulating materials are also possible.

According to 1A there is a damaged area S1 in a roof panel 102 , a damaged area S2 which also has a window 80 is affected, in the side panel 10 and a damaged area S3 across in the back panel 103 and the sandwich panel 10 . The damaged areas S. and S1 to S3 can penetrate the panels completely or only partially. As in 2 a) indicated, the damaged area shown there extends S. through the second outer skin 10c and in parts of the insulation layer 10b , but not down to the first outer skin 10a .

In 1B Fig. 3 is a rear view of the vehicle 1000 with the rear panel designed as a sandwich panel 103 , left and right side panels 10 or. 101 as well as the roof panel 102 shown.

Here is the direction shown in the drawings X a first surface direction parallel to the outer walls 10a , 10c , and in 1 also parallel to the longitudinal direction of the vehicle 1000 . A second plane direction Z also runs parallel to the outer walls 10a , 10c and perpendicular to the first surface direction X , so in 1 also parallel to the height direction of the vehicle 1000 . A third direction Y is perpendicular to the direction of the surface X , Z Spanned surface extension plane of the outer skins 10a , 10c and thus also perpendicular to the surface directions X , Z .

By applying the following using the 2 procedure described can damage the individual S. or. S1 to S3 in sections by replacing the corresponding repair sections R. or. R1 to R3 can be fixed with appropriate replacement panels, whereby in 2 the repair of the repair section R. Is referred to. In particular, if there is only a small area and relatively concentrated damage, such a repair is through partial replacement of the repair section R. of the sandwich panel 10 instead of replacing the entire sandwich panels 10 cheaper possible. In particular, any costs for dismantling and reassembly of, for example, installations and interior fittings such as wall cupboards and the like attached to the panel or a support structure can be avoided or at least reduced.

The repair section R. extends starting from an edge or side edge 20th of the vehicle essentially in a straight line up to and over the damaged area S. out. In the case of the damaged area S2 , in the one next to the sandwich panel 10 also a window 80 of the motorhome and therefore needs to be replaced, the repair section extends R2 across the entire width of the window 80 . In the case of the damaged areas S1 and S3 is a section of the sandwich panel 10 as well as a section of the rear or roof panel 103 or. 102 affected, the individual repair sections R. , R1 to R3 can be treated independently of one another within the meaning of the invention.

In 2 a) is the sandwich panel 10 in a cross-sectional view according to section AA 1a shown. The sandwich panel shows the damaged area S. on. The damaged area S. is made from the sandwich panel in a first step 10 (ie the originally damaged side panel) with a first tool W1 such as cut out by means of a rotating cutting disc along the dashed lines. However, other cutting tools such as a vibrating saw, a plunge saw or the like could also be used. Along the edges of the repair section R. (the following side edges and joining sections 20th or. 21st , see. 1 ) becomes the repair section R. - Generously enclosing the damaged area - separated. The parting surfaces created by the tool (end faces 3) run essentially perpendicular to the flat extension of the sandwich panel 10 , so towards Y , here also cutting direction Y called.

In 2 B) is the severed repair section R. shown. The damaged or repair section separated in this way R. becomes from the sandwich panel 10 removed so that an in 2 c) shown recess 24 remains behind. The recess 24 points in the case of a rectangular repair section R. three essentially straight edged or joining sections 21st and a margin or side edge 20th as end faces 3 on. Edge and joining sections 20th , 21st run at right angles to one another in the example shown. Other recess geometries, for example with a straight but inclined edge and / or joining sections, are possible. The edge and joining sections can, however, also form any free shapes such as curves or the like.

How out 2 d) results, are or will then be in the insulation layer 10b Exemptions 11a and 11b on each face 3 of the remaining sandwich panel 10 with one tool W2 educated. The tool can be, for example, a milling tool or also an insulating material 10b steaming soldering iron or the like. The exemptions 11a , 11b are essentially rectangular in cross section and extend from the end faces 3 of the sandwich panel 10 and the outer skins 10a and 10b each vertically into the insulation layer 10b into it and run over the entire length of the joining sections 21st . If necessary, further cutouts can be made for receiving in the insulation layer of the sandwich panel 10 running support structures or lines for water or electricity can be provided.

In 2 e) is a replacement panel 30th shown, that for insertion in the recess 24 or the repair section R. has been prepared. The replacement panel can, for example, have been cut to size from a sandwich panel blank using a separating device such as a band saw. The replacement panel 30th corresponds in its outer contour essentially to an inner contour reduced by an edge section (joint width) of the here rectangular repair section R. .

In 2 f) is or will be the replacement panel 30th analogous to the sandwich panel 10 at three of the joining sections 21st Corresponding end faces with further clearances 31a , 31b in the insulation layer 30b Mistake. The other exemptions 31a , 31b have one of the exemptions 11a , 11b comparable shape. A fourth face of the replacement panel 30th , which terminates the edge or the side edge 20th forms, is not provided with exemptions.

How out 2 g) can be seen, is or is in the exemptions 31a , 31b an adhesive by means of a cartridge or the like 40 , here a previously applied two-component body adhesive. To protect the outer skins 30a , 30c these can preferably be applied with protective films in the area of the adhesive application 32a , 32b must be masked.

In 2 h) are or are in the adhesive-filled clearances 31a and 31b then along the joining sections 21st Strip-shaped reinforcement elements previously cut to length and width 50a and 50b on both sides of the replacement panel 30th brought in. The reinforcement elements 50a , 50b become parallel to the outer skins 30a , 30c coming from the front sides (X-axis), so that they are directly on the outer skins 30a or. 30c issue. Along the individual recesses 11a , 11b there are five reinforcement elements on each side along the joining sections 21st used. These are for the outside with the reference symbols 50b to 50b '''', see in particular 1A and 2 j) . The reinforcement elements 50b to 50b '''' are seen in the longitudinal direction, ie along the respective joining sections 21st , spaced from each other so that the reinforcement elements do not touch.

The strip-shaped reinforcing elements 50a , 50b consist of fiberglass-reinforced plastic, as this ensures good adhesion to the outer skin, which is also made of fiberglass-reinforced plastic. When inserting the strip-shaped reinforcing elements 50a , 50b the adhesive swells 40 laterally along the X axis over how out 2 h) evident.

The reinforcing elements 50a , 50b be roughened. There can also be holes or other recesses in the reinforcement elements 50a , 50b be introduced to the contact area between adhesive and reinforcement element 50a , 50b to increase and the bond of the adhesive 40 to be supplemented by a form fit in the holes or similar.

Then also the exemptions 11a , 11b of the sandwich panel 10 with the same glue 40 backfilled, cf. 2 i) . The outer skins 10a , 10c of the sandwich panel 10 are on the areas near the adhesive by a protective film 12a , 12b protected.

In 2j) are the replacement panel 30th and the sandwich panel 10 shown before an immediate joining process. The replacement panel 30th is inserted into the recess on the edge 24 of the sandwich panel 10 joined by the replacement panel 30th edge side of the edge portion 20th coming parallel to the joining edges 21st is inserted in the direction of arrow P.

They reach over the outer skins 30a , 30c protruding reinforcement elements 50a , 50b of the replacement panel 30th in the corresponding exemptions 11a , 11b of the sandwich panel 10 a. This gets rid of excess glue 40 displaces and swells laterally (in Y-direction) inwards in the insulation layers that are not in abutment 10b or. 30b formed inner gap 23 as well as laterally in the Y-direction outwards into the not in abutment contacting of the outer skins 10a and 30a or. 10c and 30c formed joint 22nd . The same applies to the in 2 k) left, not described in detail fug 22 '.

In 2 k) the state after the edge-side joining is shown. As mentioned above, the outer skins are 10a , 10c or. 30a , 30c of sandwich panel 10 or replacement panel 30th to protect against adhesive contamination before the adhesive is applied along the joining edges 21st with a removable, here self-adhesive protective film or protective film 12a , 12b, or 32a , 32b taped off. Out of joint 22nd overflowing, excess glue 40 can be scraped off with a spatula, for example. The replacement panel 30th is smaller than the sandwich panel 10 so that the end faces of the replacement and sandwich panels are not butted together, but are joined together at a distance. In the joining sections 21st is a corresponding joint 22nd is trained.

In 21st ) is the fixation of the replacement panel assembled in this way 30th shown. The replacement panel 30th is made using clamping tools W3 , here vices, fixed or clamped with the replacement panel. Between the clamping tool W3 and replacement or sandwich panel 10 , 30th are pressure means designed as transparent plastic plates 70a , 70b brought in. The pressure medium 70a , 70b lie on top of the one with the adhesive 40 filled joint 22nd so that out of the joint 22nd excessive glue 40 , e.g. in the interior of the panels 10 , 30th is displaced so that the with glue 40 filled joints essentially level and flush with the outer skins 10a , 10c , 30a , 30c to lock.

As the pressure means 70a , 70b are designed as transparent plastic panels, the joint can be checked at any time 22nd or the joint quality possible, so that the sandwich panel can be readjusted at an early stage if necessary 10 and replacement panel 30th to adapt, for example, a uniform joint width and / or an additional introduction of adhesive into the joint 22nd can be done.

After the adhesive has had sufficient drying or drying time 40 are the clamping devices W3 and those about the clamping devices W3 as leverage 70a , 70b acting plastic plates removed again. Possibly on the outer skins 10a , 10c , 30a , 30c Adhering adhesive residues can be removed by removing the protective film 12a , 12b, 32a , 32b from the respective outer skins 10a , 10c , 30a , 30c removed. Possibly in the joint 22nd protruding adhesive 40 can be done using a tool before the adhesive reaches its final strength W4 , for example a spatula tool. This is a 2 m) shown.

Finally, it is waited until the final strength of the adhesive is reached. The plane joint 22nd can then be painted so that the in 1 shown repaired area R. in the sandwich panel 10 remains behind. No further post-processing is necessary.

The method presented here enables a quick and simple, aesthetically pleasing mending or repair of damaged sandwich panels on a vehicle. A repair kit with the necessary tools was advantageously used for the process. The example shown here does not intend to restrict the invention, so that the invention also includes obvious modifications or expansions.
