Definitions

• Wall module especially for car bodies
• the invention relates to a wall module according to the preamble of the first claim.
• a known wall module of this type (DE 43 01 763 A1) consists of two at least largely parallel wall panels, between which a filler is loosely introduced, which has a heat and sound insulating function.
• Wall panels are designed as an extruded profile with profile projections provided within the surface and consist of a light metal material, preferably aluminum.
• the second wall panel is designed as a smooth cover plate and is connected to the support webs provided within the surface of the first wall panel.
• the bluntly tapering side edges serve as welding flanks for welding with edge profiles to be attached or in between.
• the support webs are attached at a distance from the side edges, so that strips of the heat insulation can be inserted between the outer support webs and the edge profile, as between otherwise adjacent support webs.
• the disadvantage of this structure is that the support webs and their profiles only provide a linear support between the wall panels and the edge profiles necessary for the side closure must be provided and fastened as separate components.
• the invention has for its object to take measures in a wall module according to the preamble of the first claim, through which a stable structure with a simple installation option is created.
• the side edge termination in the region of side edges is achieved by end webs, which are preferably molded directly onto the first wall panel formed from an extruded profile and which are integrally formed directly on the outer edge zone to be closed.
• the end webs protect the core material, which is sensitive to transverse loads, against lateral mechanical damage.
• the end webs offer the possibility of achieving an optimal ratio of the necessary rigidity to the weight used by a design adapted to the local loads.
• the end web also takes on loads acting on the wall panel surface and keeps it away from the core material.
• a filler can be designed as a core material with a mechanical support function, preferably in the manner of honeycombs, the hollow axes of which are at least approximately perpendicular to the wall panels and which are firmly connected to the wall panels on the end face, preferably by soldering, if metallic or metal-plated honeycombs and / or wall panels are provided.
• Foams in particular made of rigid foam plastic, are also possible as the core material.
• gluing can be used instead of soldering.
• the outer edge zone of the second wall panel can also be fixed on the free end of the respective end web, which determines the distance between the wall panels according to the height of the core material.
• the wall panels are thus supported evenly over their entire area by the core material and in the edge zone at the end web. At the same time, they are held together against bulging by the core material, the core material being able to be inserted, for example, as one piece between the wall panels. It also serves as a stiffening agent with low thermal conductivity.
• the end webs can additionally carry integrally molded retaining webs in or adjacent to the respective plane receiving a wall panel, which are appropriately profiled so that they can engage in form-fitting engagement with oppositely shaped retaining webs or act as a weld pool lock if the panels are connected to the surrounding structure by welding should be.
• the holding webs can be designed as U-shaped, open to the outside and parallel to the longitudinal direction of the closing web groove webs. If the free outer leg ends are set back in relation to the outer surface plane of the adjacent wall panel, a retaining web of another wall module interacting therewith can connect flush to the adjacent wall panel.
• the holding webs on a terminal web each reach in the plane of the wall panels in question beyond the associated end web and each carry an engagement web, the engagement webs facing one another. In this way, they can be brought into engagement with the groove webs of a wall panel to be attached to them. If groove webs are formed on the side of the end web facing the core material, then the end web itself can form the particularly shortened leg of the U-shaped groove.
• end web may otherwise be provided at its free end with a support web that engages flatly under the second wall panel, in the second embodiment it is set back by the groove depth to the associated wall panel, so that the second wall panel placed thereon is again flush with the hook-shaped one Holding bridge of an adjacent component comes to rest.
• a component to be connected does not have to be a further wall module in every case; it can also be any other structural component, e.g. B. a window or door frame, spars, beams, frames or the like.
• Embodiment with groove webs set back into the panel surface the end web forms a flat end surface of the module side flank in question.

• the planar or arched wall modules 2 are each constructed from two wall panels 4 and 5, which run at least largely parallel to one another, between which a core material 6 is arranged, which is preferably designed in the manner of honeycombs, the longitudinal axes of which are at least approximately perpendicular to the plane of the section close to it of the respective panel 4 or 5.
• foam or other mechanically supporting core materials or structures can also be used as the core material.
• the end faces of this honeycomb core material 6 are permanently connected over the entire surface of the wall panels to the mutually facing sides of these wall panels 4, 5, for example by brazing, gluing or ultrasonic or laser welding. The connection method depends on the materials used for the

• this first wall panel 4 can also be used as a plastic injection molding or plastic molding z. B. with fiber, in particular glass or carbon fiber reinforcement.
• the mutually facing inner sides of the wall panels 4, 5 are smooth, in particular in the area of overlap with the core material 6. Otherwise, the second wall panel 5 can also be designed as a corresponding extruded profile.
• Each wall panel can have two z. B. provided on parallel side edges
• End webs 8 may be equipped so that by turning 90 ° of a wall panel relative to the other on the wall module formed therefrom, end webs 8 are present.
• Wall panels 4, 5 stand.
• the end webs 8 close the lateral access to the space accommodating the core material 6 between the wall panels 4 and 5.
• the second, outer wall panel 5 is fixed on the free end of the end web 8.
• End web 8 is provided at its free end with a support web 9 which engages under the surface of the second wall panel 5 and which projects into the space accommodating the core material 6.

So that the engaging retaining webs 1 1 of an adjacent wall module 2 can connect flush to the wall panels 4 and 5 of the adjacent wall module 2, the free outer leg ends 10J are opposite the outer surface plane of the adjacent one
