Description

【Technical field】
[0001]
The present invention relates to a body for a window or a door, which has a peripheral surface surrounding an end face of the isolation glass and a groove surface surrounding an edge of the isolation glass, and forms a groove for receiving the isolation glass, and The present invention relates to a device having an adhesive layer that fills at least a circumferential gap between an end surface of an isolating glass and a peripheral surface of a groove opposed to these end surfaces and fixes the isolating glass in the groove.
[Description of the Prior Art]
[0002]
In order to simplify the assembly of the isolating glass, it is known to glue the isolating glass into grooves in a profile frame (EP 1070824). For this purpose, an adhesive is applied in a band along the groove surface of the winding frame groove parallel to the isolating glass, and then the isolating glass is inserted into the groove. During insertion, the isolating glass is pressed against the surrounding adhesive strip, which takes over the connection between the isolating glass and the profile frame. A disadvantage of this known construction, however, is that the load generated by the isolating glass must be removed to the profile frame only via the channel bar surrounding the isolating glass. Furthermore, only the inner glass sheet is supported by the frame, and the outer glass sheet held by the inner glass sheet via the edge connection between the inner glass sheet and the outer glass sheet is not supported by the frame, thereby providing the end face of the isolation glass. Due to the circumferential groove between and the circumferential surface of the groove parallel to these end faces, there is the danger that one side of the outer glass sheet will sink.
[0003]
In order to be able to fix the composite glass to the shape frame of the explosion-proof window, it is known that the glass inserted into the frame groove is fixed by an adhesive layer that fills the circumferential gap between the composite glass and the groove. (EP 100 47 440). A profile defining the adhesive layer in the transition area between the peripheral surface of the groove and the groove surface surrounding the edge of the composite glass so that the adhesive layer can be limited to the end face area of the composite glass Sticks can be glued. Since the connecting portion of the profile frame remains through the profile bar, even if the adhesive layer is separated, the profile bar prevents the replacement of the composite glass. In addition, the profile rods make it difficult to drain moisture that enters between the composite glass and the frame profile, and the adhesive layer is adversely affected by moisture.
[0004]
It is known to provide an auxiliary frame that is detachably fixed to the window body and holds the isolation glass in order to replace the isolation glass that is fixed by gluing (DE-A 41 42 151). In addition, the construction cost is increased by the auxiliary frame. Furthermore, the auxiliary frame, which is fixed to the isolating glass via the adhesive layer, cannot be removed from the isolating glass.
SUMMARY OF THE INVENTION
[0005]
The object underlying the invention is therefore to improve the body for windows or doors of the type mentioned at the outset by simple means and to make use of the known adhesive connection between the isolating glass and the profile frame, especially with regard to assembly. It is possible to avoid the disadvantages, especially with regard to the possibility of replacing the isolation glass.
[0006]
The present invention is provided by providing, in the region of the cover glass plate of the isolation glass facing the groove surface, a marginal bar for an adhesive layer extending in the circumferential direction at an interval in front of the groove surface. To solve the given issues.
[0007]
Not only is the layer adhered by the limit bars locally limited to the end face area of the isolation glass, but also advantageous prerequisites for replacement of the isolation glass are provided. Because the adhesive layer can be separated to the limit bar without risk of damage to the profile frame, the limit bar is spaced in front of the groove surrounding the edge of the isolation glass. And can be broken without adversely affecting the frame. The limit crosspiece can be attached to the isolation glass or profile frame. In each case, the marginal bar can fulfill its role without limitation.
[0008]
If the marginal bar ends at a distance in front of the periphery of the isolation glass or groove, the play present will not only facilitate the insertion of the isolation glass into the frame groove, but in some cases The required replacement of the isolation glass is also facilitated. The reason for this is that the adhesive layer can be separated in the region of the play between the fixed bar and the peripheral surface of the isolating glass or groove without any residual adhesive connection. However, the size of the possible play is related to the flow behavior of the adhesive which has not yet cured when entering the circumferential gap between the isolating glass and the circumferential surface of the groove. Another possibility of complete separation of the adhesive layer is to separate the limit bar with the adhesive layer, which requires a suitable configuration of the limit bar.
[0009]
The spacing between the limit bar and the groove surrounding the isolating glass provides an advantageous drainage of moisture entering this area. To assist this drainage of moisture along the sides of the frame, the circumferential surface of the groove forms a recessed groove on the side of the limit crosspiece facing the groove surface.
[0010]
To manufacture the body according to the invention, the isolating glass is first inserted into the grooves of the profile frame, and then the circumferential gap between the end faces of the isolating glass and the circumferential surfaces of the grooves facing these end faces, at least in the circumferential range Filled with elastic adhesive up to the limit bar. When the adhesive is rounded into the circumferential gap, a tight connection is created between the profile frame and the isolating glass, without the need for additional measures. The adhesive can be injected or pressed into the circumferential gap by pressure. If the adhesive is put in before the insertion of the isolating glass, there is a risk of shearing during joining, so that no material cohesion takes place.
[0011]
The adhesive layer in the circumferential gap between the isolating glass and the groove of the profile frame surrounding the isolating glass allows a good support of the individual glass sheets of the isolating glass to the profile. This is advantageously ensured if a circumferential gap of a depth corresponding to the thickness of the isolating glass is filled with adhesive, so that the width of the resulting adhesive band is equal to the total thickness of the isolating glass. The adhesive must be sufficiently elastic to absorb the stresses due to the different coefficients of thermal expansion between the materials to be bonded and not to damage the adhesive bond.
[0012]
It is preferred to use a fusion adhesive. Since such a molten adhesive can be processed in a warm state, and the viscosity increases upon cooling, the isolation glass can be fixed in the shape frame, so that the main body is further processed within a short time after the adhesive is applied. Can be. Since the adhesive is further thermoplastically deformable, the adhesive joint remains intact during movement of the body, and the adhesive separates from the frame, as in the case of a crystalline thermoplastic adhesive. Never. The increased strength of the adhesive joint after cooling of the molten adhesive can better meet the requirements of the window or door construction in about 30 seconds to 2 hours. The use of a reactive adhesive as an adhesive offers another possibility. In this case, two-component adhesives based in particular on polyurethanes, epoxies or (meth) acrylates have proven to be particularly suitable. Such reactive adhesives allow for a rapid increase in strength and thus an associated handling strength.
[0013]
What is important for the suitability of the adhesive is to have some stability and a suitable viscosity. In this case, it must be taken into account that the adhesive can be applied on the one hand with a sufficiently large layer thickness and, on the other hand, not too great a force must be applied in order to be able to process the adhesive under pressure.
Description of the preferred embodiment
[0014]
The inventive body of a window or door according to the invention consists of a profile frame 1 and an isolating glass 2 inserted into a winding groove 3 of the profile frame 1. For this purpose, the groove 3 of the frame leg 4 forms a peripheral surface 6 facing the end face of the isolating glass 2 and surrounding the isolating glass 2. In order to fix the isolation glass 2 in the groove 3, an adhesive layer 7 that fills a peripheral gap 8 between the end face 5 of the isolation glass 2 and the peripheral surface 6 of the groove 3 is used. Since the adhesive layer 7 has a width corresponding to the thickness of the isolation glass 2, the cover glass plates 11 of the isolation glass 2 joined to each other via the spacing members 9 and the sealing pieces 10 are each independently. It is supported against the frame legs 4, which allows an advantageous load removal from the isolating glass 2 to the frame legs 4. The combined effect caused by such bonding has the advantage that the strength of the isolating glass 2 can be used indefinitely for the strength of the body.
[0015]
As can be seen from FIGS. 1 and 2, the groove 3 of the profile of the frame leg 4 forms a groove surface 12 surrounding the edge of the isolating glass 2, which groove surface 12, as in a conventional body, It is not used for fixing the isolation glass 2, but only for covering the peripheral edge of the isolation glass 2 with which the sealing piece 13 provided in the area of the groove surface 12 contacts. On the outside of the isolating glass 2, its rim is covered by a covering profile 14 and a sealing piece 15 held by the covering profile 14, the sealing piece 15 serving only as a seal and of the isolating glass 2. Does not contribute to retention. Therefore, the cover member 14 may be locked in the groove 16 of the frame leg side 4.
[0016]
To manufacture the body according to the invention, the profile frame 1 combined from the frame legs 4 is positioned on an assembling table 17 and the isolating glass 2 is provided by a conveyor 18 for its reception. It can be inserted into the groove 3. The transfer device 18 has an elevating device 20 provided with a suction bowl 19, and positions the received isolation glass 2 on the table 17 by assembling the frame 1 with the swing arm 21. Insert into frame 1. The remaining circumferential gap 8 (FIG. 4) between the inserted isolating glass 2 and the groove 3 of the profiled frame 1 can now be filled with adhesive, the adhesive then being pressed by the circumferential gap 8 Or press-fit. In order to prevent the adhesive put in the circumferential gap 8 from flowing out from the circumferential gap 8 toward the groove surface 12 on the side of the frame leg, the circumferential gap 8 is provided in the area of the outer cover glass plate 11. It is closed off by a limit bar 22 which, according to FIG. 1, protrudes from the circumferential surface 6 of the groove 3 at a distance from the groove surface 12. The circumferential gap 8 is therefore filled with adhesive only to a depth corresponding to the thickness of the isolating glass 2, ensuring a desired adhesive bond between the end face 5 of the isolating glass 2 and the frame leg 4. After the cooling and the increase in the strength caused by the reaction of the adhesive entering the circumferential gap 8, the fully assembled body is lifted off the assembly table 17 by the transport device 18 via the isolating glass 2, possibly with further processing. Can be sent to the department.
[0017]
The limit crosspiece does not need to be attached to the frame leg side 4. As can be seen from FIG. 2, the limit bar 22 attached to the covering glass 11 adjacent to the groove surface 12 also imposes requirements on the location of the adhesive layer 7 in the region of the end face 5 of the isolating glass 2. In the region of the gap that fills and remains between the limit bar 22 and the isolating glass 2 (FIG. 1) or the peripheral surface 6 (FIG. 2), or in this case also the limit bar 22 that must be separated, With the advantage that the layer 7 can be separated later.
[0018]
According to FIG. 1, the peripheral surface 6 forms a concave groove 23 between the limit bar 22 and the groove surface 12, and in some cases, prevents moisture that enters from between the sealing piece 13 and the isolation glass 2. The adhesive layer 7 does not have to be adversely affected by moisture, because it can be expelled advantageously through this groove 23.
