Definitions
- the invention relates to a frame for fastening surface elements, in particular window surfaces, to a wall structure with connecting means, according to the features of the preamble of patent claim 1. These features are known from DE-A-44 04 846.
- the document discloses window frames for glue-in glazing, which are assembled cold-glued by gluing and / or locking four straight plastic profile parts with separate corner connectors. Cold joining techniques are also preferably used to attach these frames to a wall structure.
- EP-A-0 51 5 953 discloses a window frame for glazing flush with the outer skin, which is not discussed as such and which is fastened with screws to a support frame on the structure side.
- the screws can be accessible either from the inside or from the outside of the wall structure.
- Bodies e.g. B. for railway passenger cars, as is well known, have larger cutouts for installing windows and / or flaps between two supporting, contouring columns or frames of the side walls. In the case of double-decker carriages, these cutouts are located in both the lower and upper floors. In the lower floor area the outer wall is often flat, while in the upper floor area it merges into the roof. Also for modern one-story rail vehicles, especially for vehicles with
- the invention is therefore based on the object of specifying a frame of the type discussed at the outset, which is particularly, but not exclusively, suitable for highly mechanized production in the sense of rework-free fitting to the given flat or curved wall structure.
- the individual parts of the frame are connected to each other without distortion using cold joint connections (punch rivets, pressure joining) and are preferably made from metallic pipe and / or folded profiles.
- a hybrid material construction can also be used by producing frame parts that do not have to be cold-formed from glass or carbon fiber reinforced plastic profiles (e.g. pultrusion material) and thus achieve a noticeable reduction in weight compared to metallic profile parts.
- the precision and accuracy of fit of the individual parts is preferably ensured by laser cutting.
- Fasteners on the frame side for flap hinges and closures (holes, recesses), possibly also for hinged window mechanisms, can then be introduced during the mechanized manufacture of the frame parts.
- the frame is also designed with contact surfaces to the body structure, so that it can be attached to it without warping using cold joint connections. These contact surfaces will preferably correspond to positioning aids which are to be provided on the structure side in the vicinity of the cutouts.
- Such a frame will always be arranged between two columns of a wall structure, and its crossbars, which stand upright in a wall structure, will be attached directly to them. Its longitudinal spars, which extend in the longitudinal direction of the wall structure, can, if necessary, be fastened to longitudinal struts (buckling stiffeners, purlins) or fit into their longitudinal course. If necessary, the frame parts will also include contact surfaces for attaching an outer skin. Such a frame also does not need to have webs that laterally surround the glazing or flap. Because it is inserted between two pillars anyway and its support surface is recessed, the pillars and possibly the upper and lower longitudinal profiles of the wall structure directly form these lateral webs, between which the surface element is to be fitted.
- Fig. 1 is a perspective view of a modular body
- FIG. 3 shows a perspective detail view of a frame corner
- FIG. 4 shows a side view of the frame corner according to FIG. 3.
- a wall structure 1 - here a side wall section of a double-decker railway passenger car - is constructed modularly from module elements 2 with longitudinally oriented separating joints. Their shape and contour is largely determined by columns or frames 3. Their ends are connected to one another by edge profiles 4 placed along the parting lines. Connecting elements, not shown in more detail, fix the modules to one another at the ends of abutting frame sections. In this way, circumferential columns are formed from successive frame sections.
- the frames 3, the edge profiles 4 and longitudinally oriented purlins 5 form support surfaces for a sheet metal skin not shown here.
- the wall structure 1 has a curved contour adapted to the clearance profile. The shaping curvature in the longitudinal course of the frame sections in question is generated fully mechanically by CNC-controlled roll bending.
- window cutouts 6 are provided for installing windows (or also flaps), which are located in the upper floor area within the curved surface.
- this frame 7 will be used to form support surfaces for glazing or the flaps mentioned.
- the distance between the frames 3 directly determines the maximum window or flap width.
- the above-mentioned highly flexible manufacturing method of the frames should also be used for the frame 7.
- these consist of two parallel longitudinal spars 8 and transverse spars 9, which are cold-joined to one another at cross-sectional overlaps in the corner regions of the frame 7, as will be described in more detail below.
- Blind rivets are preferably used as connecting means, which can be inserted into predrilled holes and then tightened.
- the upright transverse spars 9 of the frame which run parallel to the frames 3 in the installed state, consist of closed hollow profile or tube material without laterally projecting webs. This allows a cold deformation of the longitudinal profile that is largely free of undesired changes in cross-section, in particular by roll bending.
- the cross-section of the cross bars is somewhat flatter than the frame cross-section because the difference in thickness directly defines the depression of the contact surface for the glazing compared to the outer skin. If the window packages are to be glued, the cross-sectional width must be sufficiently wide for this.
- a conceivable fastening alternative - among other things - is to place the window packages on the frame 7 from one side and with the other side as well
- the frame forms the support surface, but its bars may be less wide than with the adhesive solution.
- the cross bars are cut to size - preferably by laser cutting - from the raw material and then bent into the desired curvature as required. Thereafter, in order to reduce weight, recesses can also be made in the wall parts of the cross bars that do not serve as the supporting surface of the glazing, preferably again by laser cutting.
- the holes for inserting the blind rivets are made in the same step.
- the longitudinal bars 8 of the frame 7 essentially have a U-cross section produced by folding from sheet metal. In each case one of the two parallel legs is part of the support surface of the frame 7. This leg is in turn sufficiently wide to be dimensioned sufficiently for the glazing to be securely glued on. Both ends of the longitudinal spars 8 are provided in one piece with connection surfaces or elements 1 0.
- rounding surfaces 1 1 are provided, which can protrude at the corners into the rectangular free frame cross section said connection and rounding surfaces and if necessary holes for pushing through connecting elements such as screws, rivets or locking ring bolts are generated. Then they are brought into their final shape by folding.
- the longitudinal spars can also, as already mentioned at the beginning, be produced as molded parts with all the necessary breakthroughs and bores made of fiber-reinforced plastic, so that a hybrid material frame is made from them 7 arises.
- angle rails 12 are provided in the exemplary embodiment, which extend along the longitudinal bars 8 of the frame 7. They can be attached to the outer skin and / or to the columns 3 via a leg 1 3 projecting from the frame.
- the respective U-web of the longitudinal spar 8 is placed against its other leg 14 and in turn firmly connected with rivets or the like.
- the dimension D in FIG. 3 thus denotes the thickness of the glazing or flap to be inserted on the frame 7, including an adhesive layer or seal thickness and the thickness of the outer skin 1 5 indicated here.
- the same dimension D also approximately denotes the difference between the thickness of the cross bars 9 of the frame 7 and the frames 3, the respective rear sides of which are aligned by means of the connecting surfaces 10. It is therefore very easy to define the depression of the contact surface F with respect to the outer skin surface by a corresponding choice of the dimensions of the frames and cross bars. Tolerance compensation is no longer necessary at this point. If necessary, minor dimensional deviations can be compensated for by specifying an adhesive layer thickness.
- the side surfaces of the frames 3 facing the frame 7 form in the entire installation arrangement the lateral boundary or contact surfaces for the glazing, which is to be attached to the wall structure 1 after the frame 7 has been fastened.
- the approximately horizontal legs 14 of the angle profiles 12 form the upper and lower contact surfaces.
