An example of such a construction is in DE 92 06 036 U1 which is also due to the Applicant.

In This document describes a horizontal rail, the a longitudinal channel with two opposite arranged longitudinal grooves includes for receiving fasteners. On the top and bottom the rail are two in the longitudinal direction of the Rail provided elongated receiving slots, into which an upper and lower wall element can be used, so that the rail not only for receiving securing devices (barrier beams, lashing straps, etc.), but also used to connect the individual wall elements becomes.

Provided Transported goods which are neither a double-decker load nor a load securing device require, is enough a smooth side wall without the above-mentioned fasteners.

from that it turns out that due to the different transport requirements a variety of different commercial vehicle bodies provided must be to meet the specific customer needs to become. The one for it Required modifications increase the planning and production costs significant.

in addition comes that many goods require a temperature-controlled transport. Especially for the transport of perishable food, which is frozen in the Chain of growers, processors and sellers must be transported, as well for the Transport of cold-sensitive Goods, insulated box bodies are used. In these isolated Box bodies, it is important that a removal of the in The heat penetrated by the vehicle body takes place before the goods themselves a temperature change experiences. This usually happens by means of a blower in a refrigerator that the warmer Air is removed and cold air flows into the interior of the structure. For the better Air distribution systems are known under the construction roof by means of suitable distributors let in the cold air and put them on the Distribute side and back. The at the top of the construction introduced cold air falls down and is from the blower sucked again.

at incorrect loading, d. H. if the charge is on the sidewall is applied, the flushing the goods were interrupted. To prevent this, sidewalls are known, by an elaborate profiling or by the attachment From distance strips the air flow the way down release.

An example of such a construction is in DE 1 00 29 355 A1 given to the applicant.

The safe rinsing the transport goods achieved by spacers, which are on the side walls of the Construction are provided.

at the well-known insulated box bodies so also occurs in addition the above-mentioned attachment problem the problem of safe cooling the goods on. To have to So in addition to the different fasteners still special cooling systems be provided, thereby increasing the variety of provided Structures further enlarged.

The invention has for its object to provide a device for a commercial vehicle body, in particular a wall, floor and / or ceiling element that is possible independent of the particular customer requirements, especially in Hin view of the different types of fastening or cooling systems can be standardized prefabricated. Furthermore, a commercial vehicle with such a device and a method for producing such a device should be specified.

According to the invention Task with regard to the component by the subject matter of the claim 1 and alternatively solved by the subject matter of claim 11. In terms of on the commercial vehicle or the manufacturing process is the task in each case through the objects the claims 12 or 13 solved.

Of the The invention is based on the idea of a component for a Commercial vehicle construction, in particular a wall element, floor element or roof element specify the at least one functional chamber with one's interior the utility vehicle construction has in use limiting retaining plate. In the holding plate are profile openings for Mounting of fasteners for installations, in particular loading beams, Sperrstan conditions, lashing straps, clothes rails and the like and / or introduced or introduced for the introduction of circulating air in the interior.

The Invention has the advantage that a multifunctional component This is made possible by minor modifications to the respective customer requirements can be adjusted. In particular, the device according to the invention allows a standardized manufacturing, reducing the planning and manufacturing costs can be significantly reduced. The device according to the invention can be equally realize as a wall element, floor element or roof element.

in the Difference to the previous constructions, the conventional ones Use fasteners such as floor rails or anchor channels, to store loading bars or locking bars, the device of the invention is based on a completely different concept. Essential for this is the functional chamber with the interior of the commercial vehicle in the Use limiting retaining plate.

In the case, that the goods to be transported neither air conditioning nor fastening or securing means require, the holding plate remains unprocessed, so that a continuous smooth inside of the structure is provided. This variant is particularly inexpensive.

In the case, the goods to be secured are transported, are profile openings for receiving fasteners arranged in the holding plate. The profile openings, for example by milling generated. This can be easy at the factory prior to assembly of the device and precise respectively. The introduction of the profile openings can also be carried out later, after the component is mounted in the commercial vehicle body.

in the The scope of the invention is thus both the functional chamber with a unprocessed, i. continuously closed holding plate claimed as well as with a retaining plate, provided in the profile openings are.

The Retaining plate is adapted to a holding function for internals, in particular loading bars, locking bars, lashing straps and the like to fulfill. This means that the holding plate or the functional chamber sufficient is stable to the aforementioned internals including arranged thereon Goods safe to store. In the case of the use of lashing straps or locking bars has the holding plate or the entire func onskammer sufficient stability on to the over to absorb the tensile forces introduced by the lashing straps or locking bars, the above the component will ultimately be introduced into the substructure.

conventional Inner cover layers of commercial vehicle superstructures, for example Plastic or thin Aluminum sheets do not show this stability and can therefore not be used in the context of the invention as a holding plate.

The Invention has the advantage that on the commonly used rail rails, Anchor rails, etc. can be waived. For load securing If necessary, only suitable profile openings in the holding plate introduced, where the desired Fixtures, such as loading bars or locking rods attached become.

The Arrangement of profile openings can essentially be chosen freely be, so that the placement of the internals very flexible to the respective customer requests can be adjusted.

In addition, can the type of load securing (loading bars, locking bars, Lashing straps etc.) chosen arbitrarily Be by the shape of the profile openings to the particular desired attachment or fuse is adjusted.

from that shows that the previously required different body variants be replaced by a structure with the device according to the invention can, without being on the varied Mounting and securing options must be waived. The production of commercial vehicle bodies can therefore be standardized, reducing the planning and production costs be lowered considerably.

Alternatively to the use of a functi Onskammer with retaining plate can be provided that the component, in particular wall element and / or bottom element and / or roof element has at least one the interior of the commercial vehicle construction limiting functional chamber, wherein arranged in the function chamber fastening means for fixtures, especially rails, perforated plates, brackets, threads and the like are (subordinate claim 11).

Instead of the holding plate are conventional fastening means in the function chamber for fixtures, i.e. Rails, perforated plates, brackets, threads and the like arranged. These fasteners are in the function chamber behind a board bounding the inner space of the structure, the plate does not take over a holding function and therefore with regard to on the stability is not subject to any special requirements.

to Use of the desired Fasteners will hold the plate only in the area of these fasteners locally removed, for example by milling, so that these from the interior of the structure accessible from are. The rest Plate remains in place, so that the arranged in the function chamber, not needed Fasteners are still covered.

there Both the unprocessed, i. consistently closed functional chamber claimed as well as those in the field of individual fasteners locally opened Function chamber.

by virtue of the factory pre-assembled and exposed as required fasteners, can be different customer requirements without major modifications Fulfills become.

Further Improvements and constructional details of the invention are disclosed in U.S. Patent Nos. 4,736,866 Subclaims specified.

at a preferred embodiment the invention, the holding plate in the region of the introduced or introduced profile openings by connecting webs between the inner sides of the functional chamber strengthened locally.

There due to the largely standardized load securing (pallet size, height of the grid boxes ...) the arrangement of the internals and thus the arrangement of the profile openings is substantially fixed in the holding plate, it is possible to advance, i. before introducing the profile openings to reinforce the relevant areas of the holding plate locally. This can For example, be done by connecting webs between the Inner sides of the functional chamber are arranged.

Concrete can due to the substantially known situation of the introduced profile openings the connecting webs adjacent to the profile openings be attached to free-standing areas. Within the free held areas between the connecting webs are the profile openings if necessary introduced easily.

The Strength of the retaining plate and thus the stability of the construction can by a suitable material selection and / or sizing the wall thickness be further improved. The retaining plate can for example high-strength GRP or CFRP composites be prepared. Other materials can also be used, such as steel or aluminum sheets, the wall thickness with regard to the required stability be interpreted accordingly.

The profile openings can Slots for forming, in particular, floor rails and partition wall rails exhibit. Into the slots can guide pins or T-sliding blocks used by loading beams or suitable carriages. The slots correspond in their function floor or partition wall rails.

Further can the profile openings be formed for receiving locking bars. These can be the profile openings a round or oval cross-section for receiving spring-loaded having axially movable retaining pin of the locking rods.

at a further embodiment are the profile openings designed for receiving lashing straps. The can profile openings be provided as short slots in the holding plate, in the appropriate Strap inserted which are connected to the lashing straps.

at a particularly preferred embodiment are in the retaining plate channel openings intended for connection to a Kluftuftsystem. The canal openings can be conceived both as inlet and outlet openings and enable a safe irrigation the transport goods arranged in the structure. This will be a good one and as possible full Air conditioning of the interior of the construction ensured.

Alternatively, the air conditioning of the structure can take place in that the air conditioning air is not introduced into the interior, but is used to actively cool the functional chamber. This means that there is no air connection between the function chamber and the interior, so no channel openings are arranged in the holding plate. Rather, the function chamber is connected to the air conditioning system such that the air conditioning the ge flows through the entire functional chamber and thus provides improved heat dissipation in the area of the component. For this purpose, the function chamber is integrated into the climatic air circulation of the air conditioning system.

This applies to the formation of the component as a wall element, floor element and Roof element, so that the entire wall of the structure is actively cooled.

Further can be provided according to the invention that a recirculation chamber with supply channels on an outside the functional chamber is arranged with the interior of the commercial vehicle body connectable or connected. With the convection chamber is an additional Level for the air supply available, whereby a particularly effective air conditioning of the construction with huge airflows allows becomes.

A Improving the insulation of the structure can be done by the circulating air chamber has insulating elements between the supply channels.

The supply channels can optionally be closed to set different temperature ranges. This embodiment is especially for Abutments suitable whose useful space, for example by retraction a partition changed can be because of the optional closeability of the supply channels in the different utility rooms different temperature ranges can be set. On this way is a particularly energy efficient air conditioning of the Construction possible.

The Isolation of the structure can be further improved by that on an outside of the Umluftkammer an isolation chamber is provided.

Further a commercial vehicle is claimed with a device according to the invention.

The inventive method for producing a component for a commercial vehicle body, in particular wall element and / or floor element and / or roof element based on the fact that at least one functional chamber with a retaining plate in use, the interior of the commercial vehicle construction limited. If necessary, profile openings in the holding plate introduced for receiving fasteners for installations. This implies that the retaining plate is sufficiently stable around the personnel to be absorbed by the internals over the profile openings be introduced into the holding plate.

To another independent Aspect of the invention is a recirculation system for a commercial vehicle body provided, the at least one loading bar with several along the longitudinal axis of the Loading beam arranged air openings includes.

With the air circulation system according to the invention, the problem is solved that in conventional air circulation systems, such as from the DE 1 00 29 355 A1 known, the circulating air is introduced via the side walls in the interior of the commercial vehicle body, so that the arranged in the middle of the interior of transport goods are less washed around, as arranged on the side walls of transport goods.

The inventive air circulation system however, one allows over the entire width of the construction distributed supply of circulating air, so that all transport goods in the interior are washed and cooled evenly.

This Advantage is inventively characterized achieved that in the loading bar or in all loading bars more along the longitudinal axis the loading beam arranged air openings are provided. In use, each loading bar is with the air circulation system connected. This can be done by the loading bar with a Supply channel is connected, which in a side wall of the commercial vehicle construction is arranged. Other feeding options the circulating air to the loading bar, for example by hoses are possible.

Of the Advantage of the circulating air system according to the invention is that the loading bar acts as an air distributor, so that a uniform cooling of all is reached in the construction of transport goods.

The Recirculation system becomes independent claimed by the device with the function chamber. A combination the functional chamber with the circulating air system according to the invention is also possible.

The Invention will be described below with reference to embodiments with reference on the attached Drawings described in more detail.

12 an interior perspective view of a commercial vehicle body with a front wall and two side walls, for reasons of clarity to represent the circulating air chamber, the function chamber is omitted.

In the 1 . 2a and 2 B is a cross section through a component according to an embodiment of the invention shown. This component, which may be a wall element, a floor element or a roof element, for example, is used for the production of commercial vehicle superstructures, in particular insulated box bodies.

As a general rule the invention includes all possible Superstructures, in particular box bodies on motor vehicles, trailers with Drawbar and semitrailers. Another area of application of the invention are exchangeable cases and Shipping containers.

The device according to the 1 . 2a and 2 B comprises three chambers, namely a functional chamber 13 , a circulating air chamber 23 as well as an isolation chamber 27 , A different number of chambers is possible, wherein for the load securing the function chamber 15 is mandatory. For example, could on the recirculation chamber 23 be waived if a cooling of the goods in the commercial vehicle body is not required. The same applies to the isolation chamber 27 ,

The functional chamber 13 is arranged on the inside of the component, that is to say on the side facing the interior of the assembly, and comprises a stable holding plate 15 that the interior 14 (S. 7 ) limited. The holding plate may also be composed of several part holding plates in a modular manner, wherein the individual part holding plates are connected by a known per se clip system.

The stability of the functional chamber 13 , in particular the holding plate 15 is sufficiently large to ensure the storage of internals including the transport goods arranged thereon. As in particular in 2 B to recognize, therefore, is the holding plate 15 through connecting bridges 18 reinforced, extending between the two insides 19 extend the functional chamber and connect them. In the 2a . 2 B is only one of the two insides 19 to recognize.

The connecting bridges 18 are designed as angle profiles and have three plane-parallel legs 18a . 18b . 18c on, with the middle leg 18b at the holding plate 15 opposite arranged inside 19 the functional chamber 13 is applied. The two outer thighs 18a . 18c lie against the retaining plate. The thigh 18a . 18b . 18c are with the respective walls of the functional chamber 13 firmly connected.

Another embodiment of the connecting webs 18 is in 10 shown in which the middle leg 18b is interrupted, so that the angle-shaped and integrally formed connecting web 18 according to 2 B in 10 is formed in two parts. This allows the distance between the perpendicular to the mounting plate 15 arranged web parts are changed.

Another training of the connecting bridges 18 is possible, for example as a double-T-carrier or -Stege.

Alternatively to reinforcement of the functional chamber 13 or holding plate 15 through connecting bridges 18 can also change the wall thickness of the retaining plate 15 be increased to the strength of the retaining plate 15 to improve. An improvement in the strength of the retaining plate 15 can also by a suitable Material selection can be achieved. Usually, the holding plate 15 designed as a steel or aluminum sheet with a suitable wall thickness. In addition, it is also possible to use modern materials, such as GRP / CFRP composites, which have excellent strength properties with a low specific weight. The strength of the retaining plate 15 depends on the force to be initiated. Since this force depends substantially on the weight of the cargo to be transported, it is at the discretion of the skilled person, the stability of the functional chamber 13 , in particular the holding plate 15 sufficiently interpreted, wherein, as explained above, the use of connecting webs 18 to reinforce the functional chamber 13 is recommended.

In the 1 . 2a . 2 B It can also be seen that on the outside 22 the functional chamber 13 a convection chamber 23 is arranged. Furthermore, on the outside 26 the circulating air chamber 23 an isolation chamber 27 intended. Both the convection chamber 23 as well as the isolation chamber 27 each have connecting webs 28 on that both the individual chambers 23 . 27 strengthen as well as the entire structure of the component. Thus, the rigidity of the component is increased, so that even heavy goods can be easily transported or secured.

The inventive component can be a one-piece wall element or floor element or roof element define. In this sense, the term "chamber" is a corresponding flat Understood structures whose longitudinal or height extension is considerably larger, as the thickness of the component. It is also possible that the component forms only a part of a complete wall or roof, so that the wall of the construction of several individual components is assembled in a modular manner.

In the 3 to 6 different embodiments are shown, with reference to which the various security systems are explained, which can be realized in the device according to the invention, the illustrated embodiments, the use of the device as a side wall 10b affect.

In 3 is the unprocessed execution of the holding plate 15 shown. It can be seen that it is an inside smooth side wall on which no fastening means are provided. This embodiment of the invention differs from conventional commercial vehicle structures in that the retaining plate 15 is in principle suitable for absorbing forces which occur during charge transport or load securing. In conventional side walls or inner cover layers such a force is not possible directly into the wall, as this separate fasteners, such as floor rails or anchor rails are provided which absorb the introduced forces. The increased stability of the retaining plate 15 or the entire functional chamber 13 is through the already described connecting webs 18 ensures that the retaining plate 15 reinforced locally, especially in the area of forces to be deployed. Alternatively, the retaining plate can 15 differ by a corresponding dimensioning of the wall thickness or by a suitable choice of material in view of the increased strength of conventional side walls.

In 4 is shown in the retaining plate 15 profile openings 16 for mounting fasteners for installations 17 are introduced. At these profile openings 16 these are anchorages 16a , which are designed to receive locking bars. These anchors 16a are formed as circular openings, in the axially movable locking pins of the (not shown) locking rods are used. These bolts are acted upon by a spring force and can be withdrawn for disassembly or removal of the locking rods.

As further possible internals, which can be arranged transversely to the longitudinal direction of the structure, clothes racks are to be mentioned, which are anchored in a similar manner as the locking bars described above in matching profile openings in the holding plate 15 are introduced.

Furthermore, in 4 short slits 16b to recognize, can be used in the bracket or brackets for lashing straps in general.

The profile openings 16 . 16a . 16b according to 4 So act as horizontally arranged anchor rail and can at any height and any distance in the holding plate 15 introduced, for example, be milled.

According to 5 are the profile openings 16 as vertically arranged slots 20 executed, which extend substantially over the entire inner height of the interior and are provided for guiding and storage of loading beams for a double-decker load. In the slots 20 are led (not shown) T-sliding blocks of the loading bars.

Next are in the retaining plate 15 Not shown detent openings provided, engage in the provided on the bar shoe of the loading beam pawls and thus lock the loading bar in the desired height. The detent openings (profile openings) are arranged at a certain distance and thus form a grid that stu stu fenartige height adjustment of the loading bars allows.

In the embodiment according to 6 are in addition to the slots 20 according to 5 channel openings 21 in the holding plate 15 provided that allow an air connection between a Kluftuftsystem and the loading bar ( 9 ). This embodiment is related to 9 described in more detail.

To reinforce the retaining plate 15 are the connecting bridges 18 the arrangement of profile openings 16 arranged or formed accordingly. For example, the connecting webs 18 in the case of floor loading ( 5 . 6 ) arranged perpendicular to the plate. The connecting bridges 18 for the load securing of standard pallets, roll containers, etc. are provided in standard heights, so that between these connecting webs 18 after introduction of the profile openings 16 Locking bar or lashing straps can be anchored. In this case, the connecting bridges 18 arranged horizontally.

For a flexible and at the same time very stable attachment or securing of cargo are the connecting webs 18 arranged in the form of a grid with horizontal and vertical grid lines, wherein the distance between each two subsequent vertical or horizontal grid lines substantially defines the minimum distance between two floor or anchor rails.

In the event that the device according to the invention is used as a roof element, can in the function chamber 13 further functional profiles, such as slots are incorporated, can accommodate the carriage for a sliding partition (not shown). The particular advantage of this is that at the same floor loading tion the support beams can be raised to below the ceiling, without affecting the loading and the air circulation.

In a further embodiment, not shown, thickening in the inner skin or the holding plate are for the transport of hanging meat in the standard distance thickening 15 provided the roof element, in which are incorporated for the assembly of Kragkonsolen of pipe runs thread. These threads are closed with a thin cover layer and can be easily opened if necessary.

In an analogous manner, as in connection with the side walls according to the 4 to 6 described, also the roof elements or floor elements may contain functional profiles, which in the holding plate 15 are introduced accordingly to receive vertical locking rods with locking pin.

Subsequently, the climate air control system based on the 7 to 12 described. This climate air guidance system can be used together with the functional chamber explained above.

The climatic air guidance system is in the circulating air chamber 23 accommodated. For the sake of better representability is in the 7 and 8th the functional chamber 13 omitted, around the rear air circulation chamber 23 to be able to recognize.

In the 7 . 8th are two wall elements 10 , in particular a front wall 10a and a side wall 10b as well as the floor element 11 shown. In the front wall 10a is a cooling unit 29 integrated with heat exchanger and blower. The front wall 10a is according to the patent application "Construction for a trailer of a truck and trailer of a truck" DE 10 2005 061 963 whose content is fully incorporated by reference into this application. The front wall 10a is accordingly thermally designed so that the insulation is given for the goods and the cooling of the cooling unit is guaranteed.

As in the 7 . 8th to recognize are in the front wall 10a supply channels 24a designed for climatic air, which is arranged vertically and with the cooling unit 29 are connected. In the supply channels 24a are channel openings 21 provided that the supply channels 24a with the interior 14 connect the commercial vehicle body. The canal openings 21 serve in this case as air inlet openings, sucked by the air under construction and the cooling unit 29 is transported. On the konkre te formation of the channel openings in Einsaugbereich or in the air outlet area is in connection with 10 returned.

The integration of the supply channels 24a in the front wall 10a has the particular advantage that it can be dispensed with the required in the prior art air return profiles, in particular hat profiles. Since the hat profiles projecting into the cargo compartment are eliminated, the loading area is increased so that more standard pallets than previously possible can be placed in the cargo space.

Instead of below the cooling unit 29 arranged supply channels 24a can in the front wall 10a a storage space can be integrated, which serves for example for receiving tools. The return air is through appropriately arranged inlet openings in the top layer of the front wall 10a introduced into this storage space. The storage room opens in a collecting hood, via which the return air to the cooling unit 29 is supplied.

The refrigeration unit 29 are two distribution channels 24b downstream, each in the front wall 10a are integrated. The two distribution channels 24b on both sides of the cooling unit 29 are provided, the conditioned air lead to the supply channels 24c in the side walls 10b as well as to the supply channels 24d in the roof element 12 ( 12 ). The in the roof element 12 provided supply channels 24d have openings opening into the cargo space 21 on, through which the climate air can flow into the hold. The climate air in the supply channels is thereby 24d transported to the end of construction (not shown).

The same applies to the climatic air in the side walls 10b passing through the horizontally arranged supply channels 24c is passed to the end of construction. The horizontal supply channels 24c are with the vertically arranged slots 20 or profile openings 16 connected for the double-decker loading, so that, as in 7 indicated by the inwardly curved arrows, the climatic air at these points in the interior 14 of commercial vehicle construction can flow. At the bottom of the inside functional chamber 13 are also channel openings 21 provided by the climatic air from the side wall 10b in the interior 14 can get. The air conditioning is in the 7 and 8th illustrated by arrows.

A particularly good rinsing of the goods to be transported is achieved in that, as in 9 shown, the climatic air from the side wall 10b in the stringers 17 is initiated. These are the stringers 17 with the channel openings 21 of the air conditioning control system according to 6 connected. The stringers 17 include further channel openings 30 through which the climate air into the interior 14 flows. The distribution of climate air in the interior 14 through the stringers 17 has the advantage that the climate air not only in the area of the side walls, so laterally from the outside into the interior 14 is initiated, but over the entire width of the interior 14 ,

Specifically, the channel openings 30 or louvers on a vertical side wall of the loading beam 17 or supporting beam 17 intended. It is understood that the channel openings 30 or the louvers on each free side surface of the support beam 17 can be arranged so that an unhindered leakage of air is made possible. In particular, it is also possible, the channel openings 30 or air slots at the bottom of the support beam 17 to arrange. As further in 9 to recognize, are several channel openings 30 or louvers along the longitudinal direction of the support beam 17 arranged. It is also conceivable to provide a continuous ventilation slot which extends in the longitudinal direction over the complete or at least approximately complete supporting beam. It is possible to use all the free side walls of the supporting beam 17 with channel openings 30 or louvers at the same time.

In 10 is good to see that the convection chamber 23 or in the circulating air chamber 23 arranged supply channels 24 with those in the function chamber 13 arranged channel openings 21 are connected. The same applies to 11 in which the connection between the chambers 13 and 23 indicated by corresponding arrows. The supply channel 24 the circulating air chamber 23 that with the canal opening 21 is connected, includes one as a spoiler 31 trained footbridge, which the climatic air to the canal opening 21 deflects, so that the climatic air with the least possible loss in the interior 14 can flow. The on the front wall 10a arranged inlet openings 21 can be designed accordingly.

For the application of the device as a side wall or front / rear wall element is that the horizontally extending supply channels 24 can be connected to one or more vertically extending air channels, through which the circulating air from the above the bottom arranged supply channels 24 down to the arranged in the region of the bottom channel openings 21 can be transported.

In the case, that the circulating air is introduced only into the function chamber and completely through them, can also be provided that the vertically extending reinforcing webs or connecting webs allow a flow of air from top to bottom, in example by the fact that the vertically arranged connecting webs interrupted at several points or formed as perforated plates are.

Furthermore, it is possible between the individual supply channels 24 Isolation elements (not shown) to arrange, through which the insulation effect of the structure is improved overall.

When using a partition, the supply channels 24c in the sidewall 10b controlled closed, so that a second temperature range is created. The supply of conditioned air for the first temperature range then takes place exclusively via the roof supply, which is sufficient with a reduced internal volume for the desired cooling. The continuing air ducts or supply channels 24d in the roof element 11 are closed by locking units of the vertical partition (not shown) sen.

In order to improve the cooling effect in the rear wall (not shown), further supply channels can be arranged in the rear wall door, which are arranged via the supply channels 24c in the sidewall 10b be fed. The same applies to an optional partition, in which supply ducts for the recirculation system are also integrated, for example those in the roof element 12 arranged supply channels 24d be fed. The same applies to the floor element 11 , In this way, a transport space enclosed on all sides is formed, the entire wall of which is actively cooled.

The external insulation by means of the isolation chamber 27 can by suitable insulating media, for. B. be carried out by foam or by vacuum chambers. The same applies to the insulating elements in the circulating air chamber between the supply channels 24 are arranged.

The aforementioned embodiments comprise modular components with insulation, air conditioning and a functional chamber for the attachment and securing of goods to be transported. The function chamber allows a multifunctional arrangement of the fasteners or fixtures in the holding plate 15 because the arrangement or the type of attachment by flexible introduction of profile openings 16 in the holding plate 15 , For example, achieved by milling. The introduction of the profile openings can be made at the factory before assembling the structure. In addition, the invention also offers the advantage that the introduction of the desired profile openings is also possible later in the assembled structure.

The Concept of the functional chamber leaves so the usual Procedure, commercial vehicle bodies according to the respective special customer requests with fasteners, such as floor rails or anchor rails but provides the advantage of a standardized component provided by minor modifications (introduction of profile openings) to the respective customer requirements can be adjusted.

The module structure of the device according to the invention also offers in the form of a further independent independent aspect of the invention, the possibility that the circulating air chamber is used without the function chamber when a fastening and securing the charge is not required, but only an air conditioning. In this case, it would be sufficient, the device with the circulating air chamber 23 and optionally with an externally disposed isolation chamber 27 equip, wherein the inner wall of the circulating air chamber 23 the interior 14 limited. In the circulating air chamber 23 are supply channels 24 arranged for the conditioned air circulating through the duct openings in the circulating air chamber 23 with the interior 14 are connected. Alternatively, it can also affect the air connection between the recirculation chamber 23 and interior 14 be waived if only a cooling of the component without flushing the transported in the structure charge is desired. In this case, the circulating air flows through the complete circulating air chamber, which is integrated in the climatic air circulation.
