Description

The invention relates to a method for producing blockings of windows, wherein in particular fast-curing plastics form the blockage.

When glazing insulating windows, window sashes or glass doors, one or more panes are placed in a prefabricated frame and fixed there. The discs are usually combined in a relatively thick and heavy disc pack. The frame consists of frame profiles. For new glazing of frames but also repair work usually plastic blocks between the edge of the disc or the disc package and the frame rebate of the frame are used (blocking). The blocks fix the discs or disc pack in a central position. In the intended use of such a window, the blocks used divert the weight of the discs or the disc pack on the pivot bearing of the window.

Fehlverklotzungen regularly lead to disc breaks, as forces and thus stresses within the discs are derived only insufficient or uncontrolled. Misplacement is generally understood to be the improper or inadequate positioning of the blocks. Damage caused by misplacing must be repaired consuming.

Methods for the fencing of windows are known. DE 195 46 847 A1 describes a method for fixing discs in the fold of a frame by edge-spaced insertion and subsequent blocking with rebate inlays. On all sides completed volume within the inserted folding inserts are filled with a liquid medium and thus the folded insert Pressurization in the direction of the edge of the disc moves until the rebate is applied. EP 2 685 043 A1 describes a window or door leaf from a frame with frame profiles and a disc pack inserted into them. In a frame gap between the edge of the disc package and the fold of a frame profile, one or more glazing blocks are used. At least one of the glazing blocks is formed with an open bottom and top surface and has an adhesive filling in the interior, which adheres the edge of the disk package with the Rahmenfalz. A disadvantage of the aforementioned methods and windows that the blocks are difficult to bring. Furthermore, a subsequent filling makes an additional process step necessary. EP 1 373 672 also describes the blockage of windows. An adhesive layer is located in a gap between the fold and insulating glazing, wherein a distance extending from the rebate surface a circumferentially extending boundary web for the adhesive layer is provided. The adhesive layer is formed of an elastic adhesive. The introduced adhesive tends to flow and thus a blockage for deriving large weight / forces is not guaranteed.

It is therefore an object of the invention to overcome the disadvantages of the prior art. In particular, it is an object of the invention to provide a method in which the limits for the plastic to be introduced are universally adaptable.

For the method for producing blockings of windows, a frame of frame profiles is provided with one or more disks arranged therein, in particular a disk package arranged therein. In this case, a gap can be formed between at least one of the frame profiles and the one or more panes. One or more customizable, in particular temporary boundaries are introduced into the gap between the frame profile and the one or more slices to confine the application area. In this case, the application area is limited by the one or more boundaries in the circumferential direction, the frame profile and the one or more discs. A hardenable plastic is introduced into the application area. Customizable limitations are understood here and in the following to mean that the limits can be selected in their dimensions. In this way, a method is provided, wherein the limits for the plastic to be introduced are universally adaptable, so that, depending on the situation, the application range for the plastic in the gap and thus the dimensions of the block can be selected. Different sizes of blocks do not have to be provided in advance. Due to the adjustable limits, the introduced plastic does not flow in the circumferential direction. Limitations in the circumferential direction are understood to mean boundaries which are arranged or can be arranged substantially parallel to the edge (s) of the one or more disks, in particular of the disk package (cf. FIGS. 2 and 3 ).

The adjustable, in particular temporary, limits can be selected from the group air cushion, Kompriband, foams, Teflon tape, silicone paper, press restrictions, hoses, expansion seals, lost limit.

The adjustable, in particular temporary, limitations may limit the application area in the longitudinal direction with respect to the frame profile and in the circumferential direction with respect to the frame profile. Limitations in the longitudinal direction are understood to mean boundaries, which are substantially transversely, in particular at right angles, to the circumferential direction along the thickness of the one or more disks, in particular of the disk package, with respect to arranged on the frame profile or can be arranged (see. FIGS. 2 and 3 ). Of course, in the introduction of two boundaries in the longitudinal direction, these differ from each other at an angle to the circumferential direction of the frame profile. The boundaries in the longitudinal direction can be arranged transversely, in particular at right angles, to the surface of the profile or can be arranged, on which the one or more disks, in particular the disk package, rests (cf. FIG. 2 ). Of course, with the introduction of two boundaries in the longitudinal direction, this may differ from one another at an angle to the surface of the profile on which the one or more disks, in particular the disk package, rest. Furthermore, in addition to one or more boundaries in the circumferential direction, one or more boundaries may be arranged transversely, in particular at right angles, to the circumferential direction along the thickness of the one or more disks, in particular of the disk package. In this way, an inserted plastic is held in position and does not flow longitudinally and circumferentially.

The method further comprises curing the incorporated plastic. Thus, from the introduced plastic a loadable block, which has the known tasks and requirements for the Fensterverklotzung. In particular, the plastic is held in position by the adjustable, in particular temporary, limits for a period of time until the plastic has hardened sufficiently and thus remains in its own position.

The application range or the dimensions of the application range depend on the gap size, preferably in the range of 1 to 5 mm; the thickness of the one or more discs, in particular the disc pack, preferably in the range of 18 to 60 or 100 mm. The length of the block can be in the range of 25 to 300 mm, preferably 50 to 150 mm, particularly preferably 75 to 125 mm. Optimal, the blockage can have a length of 100 mm. The application range may have dimensions in the range of 2 mm × 18 mm × 50 mm to 9 mm × 100 mm × 300 mm, preferably 3 mm × 36 mm × 100 mm, particularly preferably 4 mm × 40 mm × 100 mm. Since the adaptable, in particular temporary, limitations on the dimensions of the gap can be adapted, an application area with the previously mentioned dimensions can be designed. In this way, a gap with the aforementioned dimensions can be filled in areas with the curable plastic.

The curable plastic can be based on fast-curing polyurea adhesives. In general, these are two-component adhesives comprising an isocyanate-containing component A and an amine-containing component B, wherein component A contains an isocyanate-terminated component B and at least one diamine and / or polyamine and / or polyetherpolyamine. Such adhesive compositions are in EP 1 958 975 A1 and are hereby incorporated by reference. In this way, the plastic hardens quickly, which allows high clock rates in the manufacturing process. Furthermore, component A may comprise a monomeric polyisocyanate.

The aforementioned plastic based on a rapidly curable polyurea adhesive may further comprise a trimerization catalyst, especially in component B. As trimerization catalysts, in particular metal salts of a carboxylic acid, preferably potassium octoate and potassium acetate, phosphines, sodium hydroxide, potassium hydroxide, quaternary ammonium salts, 2,4,6-tris (dimethylaminomethyl) phenol and / or Mixtures of catalysts such as Jeffcat TR® (Huntsman) can be used.

The curable plastic can be adjusted such that the curable plastic when curing with the frame profile and / or the one or more discs, in particular the disc pack glued. This means that the curable plastic glued either only to the frame profile or only with the one or more discs. Alternatively, the curable plastic can also bond both to the frame profile and to the one or more panes. In this way, a bonding can be done according to the requirements.

Furthermore, an application device can be provided. By means of the application device, a, in particular fast, curable plastic can be introduced. The plastic is introduced into the formed gap between the frame profile and the one or more discs. By means of the application device, the introduction process can be optimally controlled; in particular, the application quantity and the application position can be reproducible. This minimizes mishaps.

The application device may comprise the previously described adaptable, in particular temporary, limitations. When starting the application device to an application site, a gap between the frame profile and the one or more discs are formed and introduced the customizable, in particular temporary, limitations. The boundaries define the application area or the dimensions of the application area as described above. In this way, the process flow is accelerated and high clock rates can be achieved for the blocking process.

To form the gap, a clamping, spreading or sliding device can also be used. Such a device advantageously provides for the formation of the gap between the frame profile and the one or more discs. This can also be integrated in the application device. Thus, the steps of forming the gap, introducing boundaries and introducing plastic are carried out rapidly in succession or almost simultaneously. In this way, the process flow is accelerated and high clock rates can be achieved for the blocking process.

The procedure can be done manually or automated. Likewise, the method can be partially or semi-automated. Process parameters such as positions of the block, number of lamination per frame, dimensions of the blocks, insertion times of the plastic and clock rates, can be selected and executed by the automated method application specific. For this purpose, a control unit and corresponding robot can be provided. In this way, the method with particularly high clock rates and low error rate is feasible. Missing blocks are minimized by the automated process as compared to manual insertion of blockage.

Another aspect of the invention relates to the use of a, in particular fast-curing, polyurea adhesive as a plastic in the Verkootzung windows, balcony doors, patio doors, lifting sliders, skylights, fixed glazing, facade glazing, facade elements, conservatory glazing, partitions. The usable polyurea adhesives have already been explained previously. In this way, you can take advantage of these fast-curing adhesives for manufacturing be used by blockages and high clock rates are achieved.

Another aspect of the invention relates to an application device for introducing a, in particular fast, curable plastic. The application device comprises adjustable, in particular temporary, boundaries (7), which delimit the application area. The application device can be advantageously used in one of the aforementioned methods. The application device can be attached directly to the exit point of the plastic on a mixing element (as an add-on unit) or designed as an integral part of a mixing element. The application device may consist of a supporting and sealing beam, in the sense of a carrier. The carrier forms a boundary in the circumferential direction when it is arranged on the gap. This prevents bleeding of the introduced plastic in the circumferential direction. At the ends of the carrier further limiting elements for limiting the application region in the longitudinal direction can be arranged at an angle of approximately 90 ° to the carrier. These boundary elements are inserted into the existing gap between the glass and the fold of the frame profile. These prevent bleeding of the introduced plastic in the longitudinal direction. The boundaries in the longitudinal direction seal the resulting cavity, which corresponds to the application area, laterally. The boundaries can be variable in height and thus adaptable. The carrier can limit and seal the cavity in the circumferential direction against the surface of the one or more disks, in particular the surface of a disk package. After applying, or injecting, the curable plastic, in particular a plastic as described above, as well as its curing, the application device with the limits manually, semi-automatically or automatically released and off be pulled the gap. Alternatively, the aforementioned limitations may be designed as permanent formwork, which remain within the application area.

The application device may comprise at least one material supply for providing hardenable plastic or components for a curable plastic. Of course, several, in particular two, material supplies can be provided. In this way, curable plastics can be provided in accordance with the application and the situation.

The invention will be explained in more detail below with reference to figures and exemplary embodiments.
