Description

The additional registration is based on the registrations set out above Basic idea of a profile insulated against the passage of heat or cold #for production of windows, doors, facades, partition walls and other construction elements, consisting of load-bearing profile (a) - preferably made of metal -, insulating intermediate layer (b) and cover profile (c), with (b) and (c) combined to form a combined profile (d) could be.

The subject of the additional registration is the further development of this Construction with the aim of 1.) efficient production of the composite profile 2.) more efficient Further processing of the composite profile into construction elements 3.) greater security and durability of the construction especially at higher temperatures, e.g. as a result of Sunlight 4.) extended design options, especially the visible surfaces.

With regard to the desired thermal insulation, foaming has proven itself of the intermediate space (b) with rigid polyurethane foam proved to be particularly effective. The foam also acts as a mechanical connection between the sub-profiles. The strength this compound meets the requirements at room temperature, however a weakness of the construction must be seen in that at temperatures above 80 degrees Celsius, as it does in summer sunshine can, the strength and adhesion of the hard hem significantly decreases; as well as in that precise data on its resistance to aging are not yet available. EiF The second construction-related disadvantage is the relatively high cost of supporting forms or calibration facilities to the combined Sufficient profile To produce true to size, especially since the support forms are specially adapted to each profile form Need to become.

This is especially true when foaming under pressure.

Both disadvantages are eliminated according to the invention in that the two Half profiles (a) and (c) before foaming the space (b) or before Filling in the insulating compound are connected by suitable connecting elements, which do not form a thermal bridge due to the materials and cross-sections used, however, the sub-profiles (a) and (c) connect permanently and in the mutual Fix the position as well as an exit of the filling compound from the space (b) to the outside impede. This can be done by suitable construction of the profiles and connecting bodies the internal pressure occurring during foaming to bring about the desired snug fit un use the adhesive effect of the filling compound for the final fixation of all parts will. In addition, the connecting elements can be used for filling to facilitate the insulation mass.

The drawings FIG. 13 to FIG. 25 explain the invention in some cases Examples, without being limited to them.

In FIGS. 13 to 25, (a) in each case represents the load-bearing profile, preferably of metal, dar; (c) the cover profile, which is designed to be load-bearing or non-load-bearing can be and consist of metal, plastic or other material; (b) the gap between the two profiles, generally with rigid foam or another Is filled with insulating material, but can in principle also be filled with air. If a suitable material is selected, (b) and (c) can result in a single profile be summarized.

The connecting bodies inserted between profiles (a) and (c) can i4 inielfalle made of plastic, other non-metallic materials, such as s.B. Consist of hard cardboard, metal or combinations thereof. Unless of the profiles (a) and (c) at least one is not made of metal, the connecting body can be merged with dea profiles (a) or (c), d.X. through suitable cross-mesh formation these profiles are to be replaced.

The connection body shown in cross section can either be in Form of endless profiles (Figure 14, (51), (59)) or in the form of short ones, in certain Spaced profile sections (Figure 14, (60); Figure 18, (70)) or in the form of individual, arbitrarily designed connecting elements (Figure 14, (61)) be. The profile cross-section can be one, two or more re the same or different Have fasteners.

The figures show the following exemplary designs and functions Figure 13 (50) lateral sealing lips, fastened in undercut grooves (71), Form with profile (a) a filler channel for foam build-up.

After placing the counter profile (c), trapezoidal sealing Groove (75), with the foaming pressure arising in space (b) the sealing lips on presses and contributes to the improvement of the seal.

(78) Lateral web (flange) protruding from profile (a) for relief the cover profile (c) or the connecting links from the mechanical forces, which come from the filling (glass pane etc. 3 (81)).

(55a) Fasteners made of resilient plastic that snap-fit Snap into the mushroom profiles (62a) so that the counter profile (c) simply presses on e.g. by means of squeeze rollers in a continuous process. Under Utilization of the foaming pressure in the space (b) are the connecting elements (55a) and the mushroom profiles (62a) designed so that the required tolerance only in the direction of pull in the sense of a limitation of the maximum distance between (a) and (c) as well as in the sense a Pixierwig #on (c) is adhered to against lateral displacement.

(56) Sealing lip as (50), but in two undercut grooves (57) attached (51) Sealing lip like (56), but at the same time as a connection element designed to precisely limit the distance between (a) and (c), which engages in undercuts (69).

In this case, the fastening element (55b) / (62b) by a Fitting piece (Figure 15, (82)) are replaced, soft only the lateral fixation takes over.

Figure 14 fastening element (55b) as an endless profile (59), single Profile sections (60) or circular single fastening element (61) executed, the latter attached to individual, mushroom-shaped fastening bolts (68).

Figure 16 Sealing lip (84) with labyrinth seal, e.g. designed as Plastic profile or in the form of two cardboard strips. The latter only need on the Outside to be coated waterproof, while the inside by the synthetic resin foam or the synthetic resin filling is soaked and impregnated.

Fastening element (83), on the profile (a) by pushing in resp. Screw in fastened against the profile (c) with snap lock to ensure the lateral and distance tolerance.

FIG. 17 sealing lip (85) ensures lateral and distance tolerance at the same time. The profile (c) is fixed against the profile (a) by the shape of the sealing lip (85) in cooperation with the insulating foam or filler that solidifies under pressure, reinforced by the gluing of the edges wetted by the filling compound.

Sealing lip (86) like (85), but with an inclined cross-sectional design, to facilitate the joining of the profiles and to improve the fit.

FIG. 18 fastening elements (70) (cross-sectional image (58) in FIG 19) in the form of spaced profile sections.

Figure 19 Fastening element (58), snap fit with a broad base on two mushroom-shaped ribs (65) and two lugs (66) to counter twisting (c) (a) exclude; Lateral and distance tolerance through stops on all sides.

Sealing lip (53) fastened in the undercut groove (74), forms together with sealing lip (54) filler channel. The adjacent surface of the profile (c) is toothed or roughened to improve sealing and resistance to internal foaming pressure.

Sealing lip (54) at the same time as a seal and thermal insulation of the Web (80) designed against filling (81) and outside air.

Interlocking of the adjacent surfaces of profiles (a) and (c) for improvement the sealing and better fixation of the sealing lip (54) against the internal foaming pressure.

Figure 20 fastening element ~ 57) like (58) sealing lips (52) in undercut Grooves (72), (73) attached, with groove (72) in profile (a) and groove (73) in profile (c) is located.

Toothed support surfaces (76). Sealing lips (52) towards the support surface greatly widened to improve sealing and fixation.

Figure 21 Cover profile (c) made of plastic and with the fastening elements or sealing lips combined into a single cross-section. The - U-shaped, elastically resilient cross-section (87) - (c) - (87) has two outwardly directed undercuts (88), which in the inwardly directed undercuts (89) of the profile (a) intervene and thus establish the permanent connection between (a) and (c). The stop from (88) to (89) limits the distance and the interaction with the interspace (b) prevailing foaming pressure the exact distance tolerance between (a) and (c).

A later retreat from (c) to (a) is not only through prevents the foam from solidifying in the space (b), but primarily through the plastic penetrating into the narrow gap between (88) and (98a) or (98b), which there achieves a considerably higher compressive strength and fatigue strength than in that voluminous space (b).

In addition, the effect is extraordinary in the narrow, large gap high adhesive strength of the solidified plastic an effective fixation of the profile (c) or of the web (87), (88) against any lateral and longitudinal displacement in relation on the profile (a).

The above also applies to the U-shaped cross-section (91) - (c) - (91) with undercuts (92) and profile (a) with undercuts (93).

By suitable choice of material elasticity, wall thickness, web height, The depth of the undercut and the formation of the flanks can be defined by the profile (c) in itself as is known, pressed into the profile (a) in the manner of a snap lock be so that the assembly either by simply pressing or in a Continuous process can be carried out using squeeze rollers, in principle the possibility remains open of first introducing one leg and then the other.

(95), (96), (97) represent soft-elastic sealing lips, which using the two-component extrusion on the hard-elastic profile cross-section (c) injected during the manufacturing process. Sealing lip (95) replaced the sealing strip which is normally drawn into the groove (94). Sealing lip (97) seals the profile (c) against the filling (90) (glass pane Etc. ). Sealing lips (96) and (97) effect sealing and thermal insulation of the from Profile (a) cantilevered web C98a), which relieves the mechanical load on the cover profile (c) serves against the forces exerted by the filling (90). The isolation can go through Finishing the space (b2) can be improved.

Figure 23 elastic web (99) of the profile (c) with undercut (100) engages in undercut (101) of profile (a). The foaming pressure presses (100) against (101) and causes a fixation of the connection, supported by the brought about by the plastic filling in the gap between (100) and profile (a) Bonding.

Elastic webs (109), (110), with undercuts in the mushroom-shaped Profile (iii) engaging, the foaming pressure from the space (b) pressed against (111). Elastic profile (106), one side in counter profile (107) intervening. Breakthroughs (108) mediate pressure equalization between the parts of the Space (b).

Elastic web (102) with undercut (103) engages in undercut Web (104) of the profile (a). Sealing lip (105) is counteracted by foaming pressure (104), creates a seal between the space (b) and protects it from the outside at the same time the web (102) against the foaming pressure, which otherwise the connection would open between (103) and (104).

FIG. 24 Grooves (112) structure the surface (visible surface) of the profile (c) and at the same time cover the opposite of the webs (99), (102), (105), (106), (109), (110) possibly arising during the extrusion process Sink marks which create unsightly grooves on the smooth profile surface.

FIG. 25 grooves (113) during the extrusion process by means of two-component # rus, ion or precipitated in a later process by color-contrasting material, so that the surface is divided into colored strips.

Figure 26 grooves C114) only partially filled with colored material (115), so that the surface is structured both in terms of color and plastic.

Figure 27 Different colored material (116) placed on the surface, so that the surface is also structured in terms of color and plasticity.

The main advantage of the examples explained above Construction lies in the mutual functional support of the used Elements for solving the tasks 1.) The auxiliary profiles make this easier Filling in the foam batch; Ensure auxiliary profiles and connecting elements taking advantage of the foaming pressure; precise positioning of the partial profiles to one another.

2.) The pressure-resistant filling compound that adheres to the surfaces is fixed the connecting elements in their final position and also connects those of the Points of the partial profiles that are distant from individual fastening elements are so rigid with each other that the composite profile processed as a whole and thus rationally can be.

3.) The connecting elements made from tried and tested material, e.g. polyamide secure the connection of the partial profiles given by the packing compound in the event of a fall high load, high usage temperatures or long service life.

The combined use of filling compound and prefabricated elements thus enables the shape-independent production of a fully pressure-resistant, permanent connection with good insulating properties and sufficient safety reserves.

In addition, it allows the functional separation of the support profile and cover profile a more revealing design of the cover profile without consideration to static requirements, e.g. through the use of decorative plastic materials, especially through the choice of different colors and surface treatments for the inner and outer visible surfaces.
