Description

The invention relates to a device for sealing of building openings with a frame which is adaptable to the inner light of the opening, and a fixedly connected to the frame, Abschottplatte, wherein the frame at least one of the building opening facing side surface, preferably circumferentially, an inflatable sealing element having.

Such, from the DE 4023286 A1 known device has a Abdichtrahmen, which are made of side profiles, which are covered on the outer circumference with a circumferential sealing strip on. The side profiles can be pressed apart by bracing elements and against the soffits of the building openings. Furthermore, a cover plate spanning the surface of the cover frame is provided. For sealing the corner regions of the building opening to be closed, diagonal strains are provided.

From the generic US 2,763,038 is also known a sealing frame known for building openings. This frame has a circulating hose which, when inflated, presses a separate tape, loose prior to inflation, sealingly against the inner edge of the building opening.

The GB 2 246 156 A shows a similar embodiment in which an inflatable tube is arranged in the frame, which presses a separate from the hose, mounted in the frame sealing tape indirectly to the building opening.

These known devices are quite suitable to prevent the ingress of, for example, flood through the closed building opening. However, as a result of the elaborate construction (inter alia, with inflatable tubes and separate Dichtbändem) of these known devices, a quick and easy installation of the sealing device is not possible.

The object of the invention is to provide, while avoiding the disadvantages described above, a device for sealing building openings, which has a low weight, is easy to assemble and adapts to the Oberflächenveriauf of the soffits of the building opening.

According to the invention this is achieved in that the sealing element is formed as a cross-sectionally open shell and formed with at least one frame part a tubeless formed gas-tight closed chamber, which is pressed by the pressure in the chamber of the jacket to the soffit of the building opening and with this forms the main seal plane with the building opening. Due to the overpressure, an adaptation to dimensional deviations and unevenness at the reveals of the building opening as well as a hermetic seal of the building opening against the passage of solid, gaseous and liquid substances.

In addition, no preparatory work is necessary for mounting the sealing device, it must be used only the size of the building openings in approximately adapted frame of the sealing device in the building opening. The locking and sealing of the building opening then takes place by simply inflating the inflatable sealing element.

According to one embodiment of the invention, the sealing element is designed as a cross-sectionally open, preferably rubber-elastic jacket which forms a gas-tight closed chamber with at least one frame part, this is pressed by the pressure in the chamber of the jacket to the soffit of the building opening and forms with this the Main seal level with the building opening.

It can be provided according to a preferred embodiment of the invention that the frame comprises a supporting frame construction, which forms a sealable between the building opening and the frame construction gas-tight chamber together with the sealing element, wherein it has been found to be particularly favorable when the sealing element in the profile cross-section is formed substantially semicircular. The supporting frame construction, which forms a gas-tight chamber with the sealing element, gives the sealing device the necessary stability, so that a firm connection with the masonry can be produced. Such a construction can be compared with the principle of a tubeless tire, wherein the supporting frame construction of the rim and the rubber-elastic jacket would correspond to the car tire.

According to a further embodiment of the invention, the frame comprises an undercut, preferably flexible frame profile, in which the sealing element is guided in order in this way to a preferably secure seat of the sealing element on the frame ensure and prevent slippage of the sealing element during assembly of the sealing device.

A particularly preferred embodiment further provides that the frame additionally has a load-bearing frame construction, which is fixedly connected to the frame profile and / or the sealing element, whereby the stability and thus the tightness of the sealing device is increased.

For the connection of the frame with the Abschottplatte there are several possibilities. In one embodiment of the invention, in which the complete sealing device is arranged in the building opening, so that it does not protrude from the building exterior wall, the frame on the side surfaces of the Abschottplatte, preferably circumferentially, with this firmly connected, preferably glued, arranged.

Alternatively, the frame can also be arranged on a top surface of the Abschottplatte, fixedly connected to this, preferably glued, which has been found, for example, in floods favorable for the distribution of the pressure acting on the Abschottplatte pressure when the Abschottplatte is greater than the building opening so that the Abschottplatte at least partially rests against the building exterior wall. In this way, the pressure exerted by the flood pressure is largely derived on the building wall, thus relieving the sealing element. In order to prevent the entry of liquid or gaseous substances between the building exterior wall and the Abschottplatte, according to a preferred embodiment of the invention between the (the) covering the building opening part (s) of the Abschottplatte and the building outer wall preferably rubber-elastic seals arranged.

So that the different corner formations of the building opening can be sealed, another embodiment of the invention provides that the sealing element has additional sealing parts in the corner regions of the building opening. Alternatively, the sealing element may be mitred in the corner regions of the building opening. In this case, the two sealing element parts are glued together at their corresponding cut surfaces, preferably vulcanized.

A further embodiment of the invention provides that the sealing element in the deflated state in at least one corner region of the frame has a projection, that is, that the sealing element is wider in the region of the projection than at the remaining places. Assuming that sealing elements without projections in the corner areas must experience a greater extent than on the side surfaces to close the building opening tight, it was previously necessary that the material of the entire sealing element is so elastic to the corner regions of a building opening reliable close tightly. By the projections according to the invention it is achieved that the sealing element in the corner areas no longer expands than at the side surfaces, so that the material for the sealing element only has to be so elastic that it tightly closes the side surfaces of the building opening, ie it can over a smaller Have coefficients of expansion and thus be cheaper.als the material that has been used for previous sealing elements.

Basically, there are several ways to realize such projections. Thus, an embodiment of the invention provides that the projection is formed by an additional sealing part. This variant is mainly used when the sealing element is formed circumferentially and in one piece. Alternatively, however, the sealing element may have a butt joint in at least one corner region of the frame, wherein adjacent sealing element parts are inextricably linked, preferably vulcanised, to one another at their corresponding cut surfaces, the projection being realized in such a way that the sum of the angles in a normal view of the frame, which include the not yet connected cut surfaces with the outer edges of the sealing element parts, is smaller than the angle between the outer edges of the not yet connected sealing element parts.

Another way to take into account the different requirements for the extensibility of the sealing element in the corner and on the side surfaces of the frame, according to a further embodiment of the invention is that the sealing element is at least partially, preferably in the corner regions of the frame, compressed.

By these two measures - either the formation of a projection or the compressed formation of the sealing element at the corners - is, simply put, the occurring stress that occurs in the corner regions of the sealing element due to the necessary expansion, which on the one hand extends the life of the sealing elements and on the other hand allows the selection of cheaper materials.

In order to make the handling of the sealing device as easy as possible during assembly, but also during manufacture and transport, the Abschottplatte is in the form of a lightweight honeycomb panel, preferably formed of plastic composite materials. Likewise, lightweight and stable materials are generally used for the frame profile. If one uses, for example, plastic, the production by injection molding offers.

If the device is permanently connectable to the building and designed to be displaceable or pivotable between a position closing the building opening and a position partially releasing the building opening, the device can be opened in whole or in part and quickly closed again in the event of an emergency. It is possible here flap or beam constructions, which are each one-sided, for example by means of pivot fittings, fixed to the surrounding masonry or connected to the window or Türzargenelement. With a corresponding optical design of the Abschottplatte the device for sealing the building opening is quite suitable to replace conventional shutters.

Further advantages and details of the invention are explained in more detail below with reference to the figures shown in the drawing.

The Fig. 1a and 1b schematically show the arrangement of a device 1 according to the invention in a building opening 5. In this case, the Abschottplatte 4, which is formed larger than the building opening 5, on the building exterior wall 13 at. Between the Abschottplatte 4 and the building exterior wall 13, a rubber-elastic seal 14 is arranged. The frame 2 is arranged on a top surface 12 of the Abschottplatte 4. The attachment of the frame 2, which is formed in the embodiment shown as a supporting frame structure 7, on the Abschottplatte 4 can be done for example by gluing. But other mounting options, such as a mechanical fastening by means of screws is conceivable.

The frame 2 corresponds in size approximately to the extent of the building opening, but is slightly smaller than this. On the soffits 18 and 18 'of the building opening 5 facing sides of a rubber-elastic, envelope-shaped sealing element 3 is arranged on the supporting frame structure 7. The jacket-shaped sealing element 3 and the supporting frame structure 7 together form a gas-tight closed chamber 6, in the gas via the valve 17, gaseous or fluid media, such as air, PV foam u.ä. be introduced. The resulting pressure in the gas-tight chamber 6 presses the sealing element 3 against the soffits 18, 18 'of the building opening 5, which simultaneously a fixation of the device 1 in the Gebäudeöffrtung 5 and a seal of the building opening is guaranteed against solid, liquid and gaseous substances.

It goes without saying that the application of the device according to the invention is not limited to the closing of building openings. Further areas of application can be found wherever rooms have to be sealed off from other rooms or to the outside, such as in boatbuilding, vehicle construction, aircraft construction, in the laboratory, in the sealing of furniture, in window and door seals, room dividing walls, in tunneling and mining and for sealing stationary or mobile containers, such as containers. In this case, a wide variety of shapes of polygons, different corner angle arrangements, up to rounding and circle segment training can be realized.

The low weight, the simple design and the inflatable sealing element, which is used in addition to the production of tightness for fastening, do not require pre-assembly and allow even larger sealing devices to be mounted by one person alone. In the production of the foreclosure construction, which usually takes place according to Baumaß, basically light and stable materials are used. Thus, the Abschottplatte can be made, for example, from lightweight honeycomb panels, either made of plastic composite material or aluminum. Also, the frame may be made of plastic or aluminum, with the production of injection molding is particularly suitable. The material for the sealing element will usually be formed rubber-elastic and approximately gas-tight, so that it has the necessary extensibility or elasticity with an increase in the internal pressure in the gas-tight chamber.

In the in the Fig. 2a and 2b In the embodiments shown, the frame is formed by a load-bearing frame construction 7 and the sealing element by a semicircular, curved, elastic jacket 8. The frame structure 7 and the jacket 8 together form a gastight closed chamber 6. In the frame construction 7 is further a valve 17, are introduced with the gas, gel or fluid media in the gas-tight chamber 6, respectively.

For example Fig. 2a the frame structure 7 is arranged on a top surface 12 of the Abschottplatte 4. Alternatively, however, as in Fig. 2b shown, the frame structure 7 may be arranged on a side surface 11 of the Abschottplatte 4. In this variant, it has proven to be advantageous if the supporting frame structure 7 is made in one piece with the Abschottplatte 4. In addition to the shown semicircular design of the rubber-elastic shell 8, for example, a U-shaped design of the shell 8 would be zweckerfüllend.

The Fig. 4a and 4b show two different Eckausbildungen a device according to the invention 1. In the in Fig. 4a 1, the sealing element in the corner regions an additional sealing member 15 which is glued to the sealing element 10, preferably vulcanized onto this. In the embodiment according to Fig. 4b in which the frame is formed by a load-bearing frame construction 7 and the sealing element by a rubber-elastic jacket 8, the sealing element is mitred in the corner areas, the two sealing element parts 3 ', 3 "glued, preferably vulcanized, to their corresponding cut surfaces ,

The introduction of gaseous or liquid or gel media in the preferably gas-tight chamber 6 can be done by conventional valves, for example by hand. Alternatively, however, the supply can also take place automatically, wherein the pressure supply can be monitored via pressure indicators or pressure limiting elements.

The Fig. 5a to 5c show further embodiments of the invention, with which the adaptation to different structural conditions is possible. Thus, in large building openings, as in Fig. 5a shown, the openings are divided by struts 19, whereby it is possible to keep the size of the sealing device 1 to a degree that also allows a mounting of the device 1 by a person. At the in Fig. 5b In the embodiment shown, the building opening extends to the floor. This eliminates the stopper for the Abschottplatte 4. This problem often occurs in shop windows or building entrances, as in Fig. 5b shown solved by placing a bottom rail 20. This bottom rail 20 does not have to be fixed to the ground, since it is pressed firmly against the ground as a result of the overpressure produced in the chamber 6. Out Fig. 5c It can be seen that for building openings in which a window 21 is arranged with a sill 22, the Abschottplatte 4 has a recess 23 for receiving the over the building exterior wall 13 projecting part of the sill 22. Due to the honeycomb design of the Abschottplatte 4, this recess 23 is not a particular impairment of the stability of the Abschottplatte 4.

The Fig. 6 shows an anti-burglary variant of the device according to the invention, in which on the inside of the building facing side of the frame locking elements 16 which can be connected to the surrounding masonry or with the window or Türzargenelement are arranged. In addition to the locking variant shown, inter alia, the arrangement of a detent or a screw connection would be zweckerfüllend.

In the Fig. 7a and 7b schematically shows a permanent arrangement of the device 1 in the region of the building opening 5, wherein the device 1 according to Fig. 7a between a utilization position occluding the building opening 5 and an open position which at least partially releases the building opening, which is shown in dashed lines, displaceable, for example via a beam construction, is mounted.

To Fig. 7b For example, the device 1 can be moved between a position closing the building opening 5 and a position (broken line) which releases the building opening. In contrast to Fig. 7a is after Fig. 7b However, the device 1 pivotally, for example by means of pivot fittings, attached to the surrounding masonry.

The Fig. 8 shows a further embodiment of the invention, in which the sealing element 8 has a projection 26 which is formed by an additional sealing element part 15 '. Here, the normal distance H _{2 of} the projection 26 from the adjacent longitudinal edges of the frame 2 is greater than the normal distance H ₁ extending along the longitudinal edges of the sealing element 8 areas of the longitudinal edges of the frame 2. The required in sealing elements without projection larger extent in the corner regions of Frame with respect to the extending along the longitudinal edges areas is thus avoided in the embodiment shown so that the projection 26 protrudes further in the deflated condition by the difference between H ₂ and H ₁ . When mounting the device according to the invention, the frame 2 is introduced with the sealing element 8 in the building opening 5, so that the projection 26 rests against the wall of the building opening 5. During inflation, the sealing element 8 then expands in the areas along the longitudinal edges, until it also bears against the wall of the building opening.

9a and 9b show a further embodiment in which the projection 26 according to the invention is realized in that the angle is the sum of the angles β, β ', which the not yet connected cut surfaces 24, 24' with the outer edges 25, 25 ' the sealing element parts 3 ', 3 ", is smaller than the angle α between the outer edges 25, 25' of the not yet connected sealing element parts 3 ', 3". If, as shown in Fig. 9b, the sealing element parts 3 ', 3 "connected to each other, forms a butt joint 27, wherein due to the false miter, the sealing element 8 forms a projection 26. A further advantage of such a configuration is that the sealing element 8 is partially compressed in the corner regions, so that the elongation caused as a result of the inflation of the sealing element 8 is partially compensated, at least in these areas A.

It should be pointed out that the figures are schematic representations from which no conclusions can be drawn about the actual dimensions of the device according to the invention. It goes without saying that the invention is not limited to the exemplary embodiments shown. So it would be conceivable, for example to arrange inflatable sealing elements only on two sides of the frame, while on the two opposite sides elastic, but not inflatable sealing elements are arranged. Also, the sealing of the corner areas could be omitted entirely. But it is also possible to seal only the corner areas. However, the aforementioned variants assume that the seal arranged between the sealing plate and the building exterior wall assumes the sealing function of the sealing element described in the claims. Furthermore, it would be possible to integrate in the soffits of the building openings a vacuum frame, which sucks the sealing element into the frame, and in this way establishes the tightness between the frame and the window reveal.
