Description

Mounting device for mounting a prefabricated deck on a boat deck

The invention relates to a mounting device for use in the bonding of a prefabricated deck on a boat deck according to the preamble of claim 1.

A boat deck is first and foremost usually made of a steel or plastic plate. To increase the value of the boat deck is often covered with so-called prefabricated decks, which usually consist of at least one or more ready-deck elements. These in turn usually have a wood covering on the top. The finished deck elements are glued in the prior art on the boat deck. It is irrelevant both for the embodiments of the prior art and for the embodiment according to the invention whether intermediate layers are applied or applied before the application of the finish deck. Relevant is the consideration of the bonding of the finished deck element or prefabricated deck.

It is necessary that for bonding a high pressure on the j eweilige finished cover element is applied, so that the introduced adhesive spreads flat and escapes between the Fertigdeckelement and the boat deck existing air. For this purpose, the top side of the finished cover element in the prior art is covered with a vacuum film. which together with the boat deck forms a closed volume. By applying a negative pressure by means of a vacuum system, a compressive force is applied to the vacuum film and thus to the finished cover element, whereby the air present between the finished cover element and the boat deck is correspondingly extracted.

Although this method of assembly has proven itself and can be carried out inexpensively, but j edoch - in particular depending on the stability of the finished cover elements - quality disadvantages. These consist in particular in that when the vacuum is applied, the air enclosed under the finished cover element exits at the edge of the finished cover elements, wherein at the same time the adhesive located there is also pulled out or pushed out due to the vacuum and the pressure on the finished cover element. As a result, there is an accelerated lowering of the finished cover element at the peripheral edges, while on the other hand remains undiminished enclosed air in the central region and the adhesive is far from being sufficiently distributed. This leads on the one hand to incomplete bonding of the finished deck element on the boat deck and on the other hand as a significant quality disadvantage to a not completely flat appearance. This results from the stronger lowering of the finished deck element to the boat deck in the edge areas.

Object of the present invention is therefore to improve the quality of the bonding of prefabricated deck elements on a boat deck.

The stated object is achieved by an embodiment of the invention according to claim 1 dissolved. An inventive method for corresponding assembly of a prefabricated deck is specified in claim 12.

Advantageous embodiments are the subject of the dependent claims.

A generic mounting device is initially used for bonding a prefabricated deck on a boat deck. Which kind of here the finished deck as well as the boat deck are, at first insignificant. In this case, the prefabricated deck has at least one finished cover element. The mounting device is - depending on the version - both for bonding a single prefabricated deck element as part of a larger prefabricated deck and for the complete bonding of the entire prefabricated deck used. Which type of execution is the boat deck, this is also irrelevant, as long as it is ensured that a corresponding prefabricated deck can be glued on the boat deck.

For bonding the corresponding finished cover element, it is necessary that the mounting device has at least the size of the finished cover element. Furthermore, the generic mounting device has at least one vacuum layer, which in turn comprises a vacuum connection. By means of the vacuum layer, it is possible to create a vacuum or a negative pressure via the vacuum connection between the vacuum layer and the boat deck for bonding the finished deck to the boat deck. An absolute airtightness between the vacuum layer and the boat deck is not absolutely necessary, and it is particularly advantageous if this is at least largely given. As a result, both the achievable negative pressure and the energy required for evacuation are influenced.

Thus, by means of the generic mounting device by applying a negative pressure in the enclosed area between the vacuum layer and boat deck due to the atmospheric pressure in contrast to the negative pressure in the enclosed volume, the necessary contact pressure on the finished cover element and thus on the bond can be exercised. At the same time the trapped air between the prefabricated deck element and the boat deck is largely dissipated.

According to the invention, the mounting device is now designed to include at least one rigid support plate. Whereas in the prior art, the vacuum layer consists almost completely of a vacuum film and thus has no rigidity, now a corresponding rigid support plate is used. In the realization of the corresponding negative pressure is needed here an arrangement of the vacuum layer on the upper side of the support plate. In this case, the vacuum layer can optionally cover the support plate. In this respect, the use of a regular vacuum film in addition to the support plate is still possible. Alternatively or additionally, it is also possible to form at least a portion of the vacuum layer from the top of the support plate. The upper side in this case relates to the side facing away from the finished cover element side.

An embodiment of the support plate, which is airtight overall, for the purposes of the invention, undiminished includes the vacuum layer at the top of the support plate.

An embodiment of the support plate, which has an airtight bottom and otherwise j edoch not airtight and the underside forms part of the vacuum layer is also applicable, provided that internal tearing is excluded at a bending load due to the atmospheric pressure. It should be noted, however, that even an externally barely perceptible tearing between the top and bottom of the support plate leads to a deterioration in the quality of the bond and the advantage of the invention is lost.

When a negative pressure is applied via the vacuum connection of the vacuum layer, a negative pressure is likewise produced between the vacuum layer and the boat deck, as in the prior art, but according to the invention a support plate is arranged between the finished cover element and the vacuum layer. By means of this support plate, it is possible for the pressing force generated by the vacuum to be distributed over the surface of the finished cover element.

Due to the equally present in the prior art uniform pressure distribution on the vacuum film when applying a negative pressure and the uniform pressing force of the vacuum film on the finished cover element to be bonded, however, the area distributed pressing force in the context of the invention means that the support plate rests flat on the finished cover element and the from atmo spherical pressure, evenly distributed pressing force on the vacuum layer initially on the support plate acts and the support plate in turn distributes the pressing force flat on the finished cover element. However, in contrast to the state of the art, it is not precisely the case of a surface pressure which remains constant over the entire surface of the finished cover element. Rather, it behaves in such a way that at the site of greater resistance from the finished cover element against the atmospheric pressure a larger surface pressure between the support plate and the finished cover element is present than at the location of a lower resistance. Dh in that a lowering of the finished cover element caused by the pressing force in the direction of the boat deck, with distribution of the adhesive and removal of the trapped air together with the support plate, leads to a substantially identical sinking path on the entire size of the finished cover element or support plate.

Particularly problematic in the prior art is an uneven application of the required adhesive between the finished cover element and the boat deck and an air inclusion within the adhesive layer, which promotes deformation of the finished cover element during bonding. The newly created embodiment of the mounting device using a rigid support plate, it is the first time allows to produce high-quality bonding with almost absolutely flat or shaped according to the specified surfaces of the finished cover element. A circumferential collapse of the finished deck element to the boat deck - due to the lower resistance by exiting the edge of the adhesive - is no longer to be feared. Rather, the finished cover element is maintained over its entire component size to the edge of the given surface contour. At the same time a better bonding is ensured by a further improved extraction of existing between the finished deck element and boat deck air. Thus, as a result, both the technical quality of the bond is improved and the optical impression image of a distortion-free surface of the finished cover element is maintained.

In a particularly advantageous manner, in this case, the underside of the support plate in terms of their three-dimensional geometry, the predetermined Geometry of the top of the finished cover element. As a rule, this is based on a flat surface. However, in the same way, the embodiment according to the invention can be used particularly advantageously, provided that the finished cover element has a curved shape or the like on the surface.

It when the support plate is designed such that a deformation of the finished cover element is prevented is particularly advantageous. Without the use of the support plate according to the invention, a deformation of the finished cover element can occur due to the pressing force acting on the finished cover element - as already explained above. Accordingly, it is particularly advantageous if not only the support plate is rigid in itself, but rather a deformation of the support plate and the finished cover element is substantially prevented. This requires an advantageous stiffening of the finished cover element even before a deformation thereof can occur due to the evacuation and bonding process, i. at least before a significant pressure difference between the atmospheric pressure and the negative pressure between the Fertigdeckelement and the boat deck occurs.

In the advantageous embodiment of the mounting device is ensured by the permitting air flow between the vacuum layer and the boat deck that at the onset of evacuation initially a relevant negative pressure between the support plate and the finished cover element occurs even before a corresponding negative pressure between the ready deck element and the boat deck sets. This is realized in a simple manner by an air guide in the support plate allows a rapid extraction of air between the support plate and the finished cover element.

To ensure the freedom from distortion of the support plate and the finished cover element, the bending stiffness of the support plate in a particularly advantageous embodiment is at least 200 Nm ² / m. In particular, in this flexural rigidity of the support plate is largely a deformation of the support plate and finished cover element during assembly of the finished cover element on the boat deck by a bond at Negative pressure prevents and the shaping is thus sufficiently ensured.

Due to the installation of the mounting device on the finished cover element under a vacuum, a composite, which has a total of a higher flexural rigidity than the finished cover element and the support plate in total forms. This is due in particular to the frictional force existing under vacuum between the mounting device and the finished cover element, which prevents shifts which otherwise occur during bending. From this aspect of the cooperation of the mounting device and the prefabricated cover element as a composite, it is particularly advantageous if the mounting device, i. primarily the support plate is designed so that the bending stiffness of the composite is 50% above a reference value.

Without determining the bending stiffness of the composite is in a particularly advantageous manner to ensure the freedom from distortion of the support plate and the finished cover element, the bending stiffness of the support plate at least as high as the reference value.

In this case, this reference value is specified by the bending stiffness of the finished cover element in the one direction in the extension of the finished cover element in which the higher bending stiffness is present. Dh It is usually the j eweils higher bending stiffness to choose in the two directions of extension of the finished cover element, unless the flexural rigidity in the plane of the finished cover element in all

Directions is the same.

By this advantageous embodiment of the mounting device of the particular disadvantageous bending stiffnesses of the finished cover element are compensated in the second direction. This usually occurs due to the regular execution of a prefabricated deck element with the joints changing Ho lzleisten, which cause so far transversely to the longitudinal direction of the wooden strips a very low bending stiffness of the finished deck element. Furthermore, it is particularly advantageous if the support plate substantially corresponds to the size of a finished cover element. Thus, a simple assignment of support plate to finished cover element, as well as can be ensured in a simple manner that the finished cover element is held by the support plate over its entire surface and loaded with the appropriate pressing force. Depending on the embodiment and size of the finished cover element and the support plate, it is also advantageous if the support plate corresponds to the size of a plurality of finished cover elements and thus simultaneously covers several finished cover elements. Likewise, however, it may be necessary in the presence of a plurality of finished cover elements to use a plurality of support plates, which thus correspond overall in an advantageous embodiment of the size of the finished cover elements.

Depending on the application, i. the division of the finished cover elements into areas and the assignment of the areas to a mounting device, it is also advantageous if the plate joint between two support plates is not performed in accordance with the cover gap between two finished cover elements. Thus, a possible offset between two finished deck elements is effectively prevented. It should be noted in the determination of the position of the plate joint advantageous to the concomitant loss of stiffening at the location of the plate joint by the mounting device.

In order to preserve the shape of the surface of the finished cover element on the peripheral edge of the individual finished cover element or the plurality of ready-to-install elements, it is particularly advantageous if the support plate or the support plates terminate essentially flush with the finished cover element or the finished cover elements. Thus, a disadvantageous too strong or too weak pressing of the finished cover element can be prevented at the peripheral edge.

When using a plurality of support plates, in particular in a not completely over the support plates covering vacuum film, it is particularly advantageous when along plate joints between the support plates a deformable joint seal is used. This is to be carried out so that the vacuum existing during use between the vacuum layer and the boat deck is essentially ensured. Which type of joint sealing is here is irrelevant at first. In this case, this can be placed both for mounting the finished cover elements on the support plates above the joint, as well as also attached, for example, as a rubber seal or the like on one edge side of a support plate.

Furthermore, it is particularly advantageous for generating the most efficient vacuum possible without unnecessary loss of energy when the vacuum layer is provided with a circumferential deformable edge seal. In this case, the edge seal can be connected to the boat deck lo se, thereby ensuring a vacuum between the vacuum layer and the boat deck. Likewise, it is initially irrelevant which type is the edge seal. This can be, for example, a sealing material applied for mounting, for example putty or silicone.

However, it is particularly advantageous if the vacuum layer is at least partially formed by a vacuum film. As a result, a cost-effective sealing means is provided which can be reused, applied quickly and in turn removed. In this case, the vacuum film on the one hand be carried out in vo full size of the mounting device and thus essentially correspond to the Vakuumfo lie from the prior art. However, depending on the design of the support plate, it is equally possible to form, in particular, the joint seal and / or the edge seal by means of the vacuum film.

To realize the support plate can be used as a particularly cost-effective means and in particular while allowing the use of a regular vacuum layer of the prior art, a non-airtight or porous support plate. As a result, the evacuation of the area between the vacuum layer and the boat deck can be achieved in a simple manner and, in addition, there are no further particularities. necessary measures. It is also advantageous in this case that no exact assignment from the vacuum connection in the vacuum layer to any otherwise possible vent openings or to the edge of the mounting device is necessary, as venting is possible even in the support layer in this transverse direction as well. This is suitable as a support plate in particular a

Flat pressed chipboard.

In order to realize the deformation freedom of the finished cover element when using the support plate, it is particularly advantageous if the support plate has one or more ventilation openings on the underside facing the ready-to-cover element. For this purpose, the vents are to be connected to the running in the plane of the support plate air channels. Likewise, however, it is equally possible to incorporate open air ducts in the manner of grooves on the underside, which at the same time form the ventilation opening here. In this case, it is necessary that the air ducts are designed or laid in such a way that they are connected to the vacuum connection. This means that when a vacuum is applied to the vacuum connection of the vacuum layer, a corresponding negative pressure is simultaneously generated in the air ducts and thus at the vent openings.

The connection of the air ducts with the vacuum connection can in this case erfo lling, wherein depending on the design of the support plate, one or more of the support plate penetrating vent openings may be provided. Their arrangement and number will also depend on the design of the vacuum layer. Correspondingly, a singular vent breakthrough may be provided in an arrangement under a singular vacuum connection, as well as a plurality of vent apertures, in particular when a vacuum film is arranged above the entire support plate or when using a plurality of vacuum connections, may become necessary. When using a support plate with integrated upper section of the vacuum layer, it is particularly advantageous to arrange a vacuum connection to the support plate and to conductively connect with corresponding air ducts. This advantageous embodiment with the ventilation openings on the underside of the support plate, it is ensured in a particularly advantageous manner that a deformation of the finished cover element is prevented when using the mounting device. When a negative pressure is applied to the vacuum connection of the vacuum layer, the connection to the ventilation openings by means of the air ducts leads to an abrupt suction of the finished cover element onto the support plate. This is achieved here before any significant lowering of the finished cover element and the support plate due to the pressing force applied by the vacuum on the vacuum layer. As a result, a quasi-permanently connected unit of support plate and finished cover element is achieved for the duration of the evacuation and thus the bonding, which is characterized overall by a particularly high flexural rigidity. After completion of the bonding of the finished deck element on the boat deck j edoch, however, in contrast to alternative conceivable designs for the connection of prefabricated deck element with support plate, the support plate can be completely removed without j eful traces of the finished cover element.

To realize a high flexural rigidity and at the same time low weight, it is particularly advantageous if the support plate has a multi-layered construction as a lightweight board. Here, the top of the support plate is to be provided with an upper high-strength support layer. This should have a low material thickness in relation to the total material thickness of the support plate. On the opposite side of the multilayer lightweight board is also required to realize the high bending stiffness of a lower high-strength base course with equally low material thickness. Between the two high-strength base layers, it is particularly advantageous to arrange a venting layer, which in this case may have a lower strength, but in particular is characterized by a low density. In relation to the thickness of the support plate and in particular to the strength of the base layers requires a relatively larger material thickness of the middle venting layer to realize high bending stiffness of the lightweight panel. Here, in terms of the formation of a Composite with the finished cover element in the use of the upper support layer strength are performed and the lower support layer to a lower material thickness, density and / or strength sufficient.

It is particularly advantageous if the middle venting layer can simultaneously effect a venting from the venting openings to the vacuum connection. This requires appropriate air permeability of the venting layer. This can be realized here in many ways. On the one hand, it is conceivable to use an open-pored foam. This can be, for example, an aluminum foam.

This can also be an extruded chipboard with hollow chambers. Likewise, it is conceivable to incorporate appropriate air ducts on one side of the venting layer prior to the production of the lightweight building board. Likewise, the venting layer can in turn be constructed in a multi-layered manner, and thus air ducts, possibly in different planes, can be incorporated in the venting layer.

It is particularly advantageous in this case if the upper support layer at the same time forms a portion of the vacuum layer. By airtightness of the upper support layer, a portion of the vacuum layer is already formed, without the need for a further agent in this area. On the other hand, it is necessary in an advantageous manner the vents in the lower support layer. These can be designed here in the manner of holes and / or perforations. Particularly advantageous is the execution of the lower support layer, if this, comparable to a fabric, is permeable to air. For example, this may be an incompletely filled fiber reinforced plastic layer.

This particularly advantageous embodiment of the mounting device with a support plate in the manner of a lightweight board with an airtight upper support layer, an air-conducting vent layer and an air-permeable lower support layer allows venting in a simple manner without additional funds. The realization as a lightweight board continues to be a large-scale deployment feasible and in the distance, for example, a plurality of ready-deck elements covered with a single support plate, wherein the handling of the support plate due to its low weight is undiminished.

Although the adhesive requirement can be reduced by the newly created embodiment according to the invention and leakage of adhesive on the edge of the finished cover element can be reduced by a multiple over the prior art, nevertheless a corresponding leakage of the adhesive is not excluded in each case. In order to prevent adhesion of the finished cover element to the support plate, the support plate is therefore provided with a cutout at least in sections along an edge of a finished element in a particularly advantageous manner. In this case, the cut-out also serves as an air channel and is in this connection in connection with the vacuum connection. The air enclosed between the finished cover element and the boat deck can thus advantageously be removed therefrom, whereby in particular it is achieved that a slight leakage of adhesive on the edge of the finished cover element does not lead to the undesired bonding to the support plate.

In addition to the execution of the mounting device with a support plate or a plurality of support plate in a plane, the mounting device can also be performed in a particularly advantageous manner with two or more superposed in layers support plate and / or spacer plates. Here, the top of the finished deck element pioneering support plate is particularly advantageously designed in a manner previously described. The underlying additional support plate or spacer plate obviously requires no air-tightness, but rather has a particularly advantageous good air permeability. Likewise, as in the basic idea of the formation of a composite under vacuum support plate in the singular design and finished cover element with friction-prevented displacement and thus high bending stiffness and a multilayer design with upper support plate and other support plate and / or spacer plate leads to an increase in flexural rigidity. A distance plate is thus characterized in particular by the fact that a free air permeability is given and by a greater strength in contrast to the upper support plate. By increasing the effective thickness of the composite, an increase in the flexural rigidity is achieved with little effort. The spacer plate requires similar to the venting layer in a lightweight board only a low strength and thus can be, for example, a hollow-chamber extruded chipboard.

Although the amount of adhesive is relatively low and the descent of the finished deck element to the boat deck, in particular due to the design of the mounting device with support plate according to the invention, is relatively accurate calculable, it is particularly advantageous that when using multiple support plates these aligned to each other by means of connection means and / or connected can. Thus, it can be ensured that two adjacent support plates perform the substantially same lowering. Here, the connection means can be designed both in the manner of a tongue and groove connection, as well as by means of tabs and recesses, as well as pins and holes can be used to align two support plates to each other or to connect.

In addition to the mounting device according to the invention is an inventive method for mounting a prefabricated deck on a

Boat deck presented. Likewise, in this case, the prefabricated deck comprises one or more finished cover elements, wherein a mounting device is used, which has at least one support plate and a vacuum layer.

First of all, in accordance with the prior art, a coating of adhesive is applied to the underside of the finished cover element and / or the top of the boat deck.

Nachfo ling the finished deck element, also as in the prior art, placed on the boat deck at the intended location. Now, however, contrary to the prior art, the support plate is placed on the finished cover element. It is immaterial here, first, whether the support plate already forms at least a portion of the vacuum layer.

In the fo lenden is - unless the support plate has the complete vacuum layer integrally - the vacuum layer or at least a portion of the vacuum layer on the support plate or the support plate surrounding placed. This results in the generation of a substantially closed volume between the vacuum layer and the boat deck. If a complete self-contained vacuum layer is placed on the support plate, this corresponds to an embodiment comparable to the prior art.

In the present case, in accordance with the prior art, a vacuum is applied to a vacuum port of the vacuum layer, thereby forming a vacuum between the vacuum layer and the boat deck. In this case, it is initially irrelevant what degree reaches the negative pressure, with an absolute vacuum is not required.

Contrary to the mode of action in the prior art, a novel effect is now achieved by means of the vacuum, wherein initially a surface contact of the finished cover element to the support plate erfo lgt. This already occurs even before there is a significant drop in the finished deck element to the boat deck. Due to the flat contact of the finished cover element to the support plate deformation of the finished cover element is substantially prevented.

Consistent with the prior art is carried out by the application of the vacuum, now nachfo lying, a substantial suction of the residual air between the finished deck element and the boat deck. Due to the procedure according to the invention, however, more residual air can be removed from the area than is possible in the prior art.

By sucking off the air between the prefabricated deck element and the boat deck, a lowering of the finished deck element onto the boat deck accompanied by distribution of the introduced adhesive. Although this also occurs in the prior art, j edoch achieved by the inventive method that the sinking of the finished cover element now takes place largely free from deformation.

Likewise, in accordance with the prior art, curing of the adhesive occurs during the process, resulting in a strong bond between the finish cover element and the boat deck.

By the newly created method according to the invention using the support plate is achieved for the first time that the finished cover element can be glued without deformation on the boat deck and is not deformed due to the different adhesive and residual air conditions below the finished cover element.

It is particularly advantageous if, for the application of the method, a mounting device, as described above, is used.

The embodiment of the invention makes it possible to continue to leave the support plate temporarily as protection of the finished cover element for further assembly of the boat on the boat deck in an advantageous manner after curing of the adhesive. While, in contrast, only a vacuum film is used in the prior art, which ensures no significant protection of the finished cover elements, j edoch by using the support plate damage to the finished cover element - which often has a high-quality wood covering - be prevented. Thus, further assembly work on the boat can safely be carried out without the need for an additional protective measure of the finished deck.

The use of the method is particularly advantageous when the finished cover element has a one-piece or multi-part deck covering which can be seen and walked on the boat deck and a directly or indirectly underlying support plate, substantially in the size of the finished cover element. Here is the use of the Method particularly advantageous if the deck covering is a changing with the joints wood flooring.

In the following figures, exemplary embodiments of a mounting device according to the invention are outlined.

Show it:

Fig. 1 shows a first embodiment of a mounting device

comprising two support plates with topside vacuum foil;

Fig. 2 shows a second example of a mounting device with a

Support plate and top vacuum foil;

Fig. 3 shows another embodiment with a connection of two

Support plates;

Fig. 4 shows another embodiment of a mounting device using a lightweight board.

In FIG. 1, first of all, a boat deck 21 is sketched on the lower side. This has a compensation layer 22 on which the finished deck 24 is to be bonded by means of the adhesive 1 9. In the example case, the finished deck 24 comprises two finished cover elements 25 a and 25 b, which are separated by a cover gap 26.

The exemplary mounting device 01 first makes use of known vacuum film 1 1 as a vacuum layer. This has in this case a vacuum connection 12, by means of which a connection 1 8 can be made to a vacuum system. This makes it possible to produce a corresponding vacuum in the volume between the Vakuumfo lie 1 1 and the boat deck 21.

To realize a mounting device 01 according to the invention, two support plates 02a and 02b are used by way of example in this embodiment, which are separated from each other by a plate joint 06. Through the plate joint 06 can also vent below the support plate 02a, 02b and between the finished deck 24 and the boat Deck 21 done. On the underside, the support plates 02 on air channels 04, which also form vent openings here. The way in which the air ducts 04 are arranged, is initially irrelevant. At least the air ducts 04 are on their spatial arrangement in connection with the top of the support plate 02 and thus with the vacuum port 12, that is, for example, by a grid-like arrangement up to the edges of the support plates 02nd

Also sketched is a cutout 05 in the case of the respective support plates 02, which 05 is located above the plate joint 26 in this case. By this cutout 05, the evacuation is promoted on the one hand in the manner of an air duct, wherein in particular a possible leakage of adhesive 19 through the cover gap 26 does not lead to a bonding of the finished deck 24 with one of the support plates 02.

It is obvious how, when applying a vacuum to the vacuum port 12, an abrupt evacuation of the area between the support plate 02 and the finish deck 24 begins even before any relevant evacuation of the area between the finish deck 24 and the boat deck 21 is performed. This advantageous embodiment is essentially a vo llflächiges applying the ready deck elements 25 a and 25 b to the j eweiligen support plates 02 a and 02 b, before a significant drop of support plate 02 and finished deck 24 on the boat deck 21 is used. Thus, a connection between the support plate 02 and finished cover element 25 is virtually achieved due to the negative pressure. This essentially prevents an otherwise possible deformation of the respective finished cover element 25, which is particularly critical in the edge region.

As an alternative to FIG. 1, an exemplary mounting device 3 1 is sketched in FIG. 2, which comprises a single support plate 32. Here, the support plate 32 is provided with a plurality of vent openings 33, which produce a connection between the lower-side air channels 34 and the vacuum port 12 of the vacuum film 1 1. In contrast to the previous embodiment, by way of example, the boat deck 41 does not have a leveling layer, but is used directly with provided the adhesive. To compensate for corresponding unevenness of the boat deck 41, the prefabricated deck 44 has an associated compensation layer 47 in the case of the respective prefabricated elements 45 a and 45 b. Otherwise, the bonding between the finished deck 44 and the boat deck takes place in the same way as in the previous exemplary embodiment from FIG. 1, wherein adhesive 19 can escape between the cover gap 46. For this purpose, the support plate 32 also has a cutout 35 for preventing adhesion of the support plate 32 with the finished deck 44.

FIG. 3 shows a further exemplary embodiment of a mounting device 5 1, wherein, in contrast to the previous embodiments of FIGS. 1 and 2 in this embodiment, the mounting device 5 1 with two support plates 52a and 52b are coupled together by means of a tab and a recess 59. This ensures in particular that a smooth transition between the finished deck elements is realized. In this case, it can not come to a greater decrease in the support plate 52a in contrast to the support plate 52b when using the mounting device 5 1. This is particularly relevant if, for example, the finished cover element is glued under the support plate 52b at a previous time and the finished cover element under the support plate 52a at a later time.

In the figure 4 now deviating from the previous examples mounting device 71 is outlined as a particularly advantageous embodiment of a mounting device according to the invention. Evident is again the execution of the mounting device 71 with two support plates 72a and 72b. These are, however, not made of a solid material, but in the manner of a lightweight board. This lightweight board in this case has an upper support layer 83, an intermediate venting layer 84 and a lower support layer 85. The support layers 83 and 85 are in this case made of a material of higher strength, while on the other hand the vent layer 84 is relevant to the realization of a distance between the support layers 83 and 85 to achieve a high flexural rigidity of the support plates 72a, 72b. At the same time forms in this embodiment, the upper support layer 83 a portion of the vacuum layer 8 first Here, the vacuum layer 8 1 is formed in the region of the plate joint 76 between the two support plates 72 a and 72 b of a vacuum film 86 also as a portion of the vacuum layer. This can be both LO se on both support plates 72a, 72b placed in the edge region as well as also already be connected in advance with a support plate 72a or 72b.

Furthermore, this advantageous embodiment in the area of the venting layer 84 on air channels 74, which are incorporated centrally within the venting layer 84. To realize this, for example, the venting layer 84 can also be designed in two layers and glued to each other accordingly. The connection of the air channels 74 to a vacuum system is made possible by the direct integration of a vacuum port 82 in the support plate 72. The vent openings 77 for the correspondingly advantageous suction of the finished cover element are in this case realized in a simple manner by holes 77. Furthermore, this embodiment outlines a corresponding cutout 75, which may be located above a cover gap between the finished deck elements.
