Abstract

The device consists of a profiled base strip (1), a spacer (2) and a profiled cover strip (3), which can be set by means of toothing (24, 33) at a suitable distance from the profiled base strip (1) and thus adapted to the thicknesses of the glass panes or infilling panels (4) to be clasped. The profiled base strip (1) has a supporting and sealing region (12) on each side. This region comprises sealing lips (14) and a projection (15) with a convex supporting surface (16). The sealing lips (14) are sufficiently flexible to permit tilting of a pane (4); thanks to the convex supporting surface (16), however, the latter always rests on the projection (15). The flexibility is facilitated further by a constriction (17). In this way, it is readily possible to construct and seal perfectly even curved building parts, such as, for example, barrel vaults or domes. The profiled base strip (1) and the profiled cover strip (3) always remain the same. The adaptation to panes (4) of different thickness is achieved, in addition to adjusting the toothing (24, 33), simply by means of spacers (2) of different height. This simplifies storage considerably. <IMAGE>

Description

DESCRIPTION

The invention relates to a device, essentially made of elastomer, for the simultaneous holding and sealing of fixed glazing or filling elements on flat or curved outer sides of the building. This device is therefore suitable for roofs of all inclinations and shapes, i.e. H. from flat-pitched to steep roofs and from barrel vaults to domes and for vertical facades, in straight or curved form.

In such a facility, the requirement is that it needs as few individual parts as possible, so that it simplifies storage to the utmost. It should also be possible to mount it largely independently of the weather, using simple means and without too high demands on the processing personnel. It must also guarantee all the demands made of modern holding and sealing devices (so-called glazing systems), such as firm anchoring of the elements, safe and permanent sealing, perfect ventilation of the front edges of the elements and safe removal of any penetrated meteor or condensation water.

So far, various types of construction are known, each consisting of a combination of solid supporting structures, which absorb different forces from wind, snow and dead weight, and seals made of sealing compounds and preformed sealing profiles. The supporting structures are divided into supports, beams, transoms and. s. w., So elements that statically determine the stability of the building or at least individual parts of it, as well as in frames or rod-shaped elements for receiving the glass panes or filler elements and for fastening the seals mentioned. The supports, beams and. s. w. are made of bending and pressure resistant material such as steel, aluminum or wood. The frame or rods can also consist of it or of relatively hard and rigid plastics. Although metals have high strength properties, they are also difficult to machine, especially if they are to be bent in the longitudinal direction. Their thermal conductivity is high, which leads to so-called cold bridges, i.e. places with heat loss and condensation, in an insulated building outer skin. This disadvantage can only be remedied by a complex separation in the inner and outer shell with an insulating area in between. Because the conductivity for structure-borne noise is also high, further measures must be taken to contain it. Although these disadvantages are much smaller for wood and plastics, bending in the longitudinal direction is also difficult and expensive. All of these materials have different thermal expansions; In the case of wood, corresponding changes in length due to swelling or shrinkage must be taken into account, which at certain intervals necessitate construction joints that are difficult to seal.

The invention now aims to overcome the disadvantages mentioned both by the choice of a suitable material and by an appropriately shaped design

avoid or at least minimize. The aim is to create a device that dissipates the forces that occur in the supporting structure, seals well and can be easily bent by hand on curved surfaces.

Such a device is characterized according to the invention by the features of claim 1.

Embodiments of the devices according to the invention are explained in more detail with reference to the accompanying drawings; show it:

Figure 1 shows a cross section through the device;

Figure 2 shows another embodiment of the spacer;

Figure 3 shows another toothing between the spacer and cover profile, and

Figures 4 + 5 the formation of a node at intersecting facilities.

The device is composed of three main parts, which are individually manufactured and then assembled, namely a basic profile strip 1, a spacer 2 and a covering profile strip 3. Basic profile strip 1 and covering profile strip 3 each have a glass pane or a filling element 4 between them on both sides. The three parts will now be described in detail.

The basic profile strip 1 has a flat strip 11, the width of which corresponds to the supporting structure on which it comes to rest. The bottom is smooth; Anchoring feet or the like are dispensed with in order to be independent of the supporting structure element. The basic profile strip 1 is usually connected to it by gluing, occasionally also by nailing, screwing or tacking using staples. On the two longitudinal edges of the flat strip 11, i.e. at the ends of the cross section shown, there is a support and sealing area 12, which consists of a rib 13 projecting perpendicularly from the flat strip 11, essentially trapezoidal and rounded at the top, and two on both sides of it protruding sealing lips 14 is composed. Each rib 13 sits on the flat strip 11; it is provided on its upper side with a nock-like projection 15 protruding from the common area of the two sealing lips 14 with a bearing surface 16. This is convex. The two sealing lips 14 together form approximately a semicircle. The height of the projection 15, the convex contact surface 16 and the semicircular arrangement of the two sealing lips 14 allow a stepless angling of each of the two glass panes 4 from the position shown by about 100 each in both directions of rotation. Such an angling of the glass pane 4 or the filling element is shown in the left half of FIG. 1, the tilting around the bearing surface 16 also being recognizable. It should be mentioned here that the sealing lips 14 naturally bear against the pane 4; they are shown here in the undeformed state. The bend is for the design of curved or curved building facades or roofs such. B. barrel vaults, domes or domes are crucial. A constriction 17, which is arranged in the rib 13 directly below the attachment point or root of the two sealing lips 14 and which also facilitates the tilting of the sealing lips and thus the disk 4, also helps with this angling.

The ribs 13 are used to derive the proportional load of the disc 4 resting on them, including additional loads, from wind, in the case of obliquely or approximately horizontally lying discs, also from snow, in the flat strips 11 and thus into the supporting structure.

Two ribs 18 are generally also provided in the middle of the flat strip 11. They serve as a guide or centering means for the spacer 2 to be accommodated

A rib is also sufficient. The spacer 2 delimits, with the respective support and sealing area 12 and the associated upper side of the flat strip 11, one channel 19 each for draining off any moisture that may occur due to leaks or condensation. At the same time, this channel also provides pressure equalization with the outside of the building exposed to the weather, i.e. in the event of pressure fluctuations as a result of wind gusts, and also serves as a so-called vapor pressure equalization chamber in order to prevent condensation water forming on the end face of the pane or the filler element 4, or at least to dismantle it quickly. The vapor pressure equalization is important in order to avoid a pressure drop between the ventilated duct 19 and the outside of the facade; then the sealing lips are only stressed by the kinetic energy of the water hitting the disc 4 (downpour) and not additionally by the pressure drop.

The spacer 2 is now to be shown. It holds the basic profile strip 1 and the covering profile strip 3 at the correct distance from one another and transmits the forces which arise from the contact pressure of the latter to the pane 4, as well as any suction forces on the pane 4, into the basic profiled strip 1 and thus into the supporting structure. It has two legs 21, which are connected to one another via at least one transverse web 22, but usually two transverse webs 22, 23, and each have at their free ends a toothing 24 which is executed against the respective other leg 21. The toothings are not exactly at right angles to the legs 21, but rather are inclined obliquely towards the transverse webs 22, 23, so that in the case of forces which act upward on the cover profile strip 3 to be described, this is even more drawn into the toothing 24.

In the case of two transverse webs 22, 23, a rectangular cavity 25 is formed between them and the two legs 21. The only or lowest crosspiece 22 is not arranged entirely at the end of the two legs 21, but rather at a certain distance therefrom, so that there is a recess 26 which, with a corresponding thickening of the ends of the legs 21, exactly on the rib or ribs 18 the basic profile strip 1 fits and thus centers the spacer 2. However, it should be noted that the spacer 2 is not connected to the basic profile strip 1; namely, it is fastened directly to the supporting structure by means of screws or nails, so that these connecting elements thus pass through the transverse web (s) 22, 23 and the flat strip 11 of the basic profile strip 1. These connecting elements then also absorb the tensile forces of the spacer, which arise or from suction on the disks 4; The basic profile bar 1 practically only transfers pressure forces due to its own weight and wind pressures to the supporting structure.

The spacer 2 can occur in three different embodiments depending on the requirements. As already mentioned, a transverse web 22 is sufficient for low requirements; the toothing 24 remains as shown on the upper part of the free ends of the legs 21. The thicknesses of the legs 21 and the transverse web 22 are designed differently depending on the bending strength of the material used. Since the greatest forces act on the crossbar and at the same time the greatest stresses occur here due to punctiform anchoring on the supporting structure (screws, nails), it is made stronger, generally one and a half times as strong as the legs 21.

The second embodiment is that according to FIG. 1, that is to say with the additional crosspiece 23, which together with the crosspiece 22 forms the cavity 25. In these can

namely a metal rod is inserted, which then acts as a kind of reinforcement; because of its small dimensions it is easy to bend in the longitudinal direction, on the other hand it is sufficiently stiff to distribute the individual forces emanating from the anchorages on the supporting structure over a larger distance in the longitudinal direction (i.e. perpendicular to the plane of the drawing), so that local peak stresses in the spacer are avoided can be. The spacer is thus stressed more evenly and is therefore more resilient despite the same dimensions. The metal rod is provided with holes for the passage of the screws or nails.

If the requirements increase even higher, a third variant of the spacer 2 according to FIG. 2 is used. This is no longer made of elastomer like the two previous variants, but at least partially of metal. Because of the much higher strength, the cross bar 23 can be omitted again in the all-metal design, but the teeth 24 are extended to the cross bar 22. Where the spacer 2 comes to rest on the basic profile strip 1, laterally projecting rails 27 can be provided. These then serve to accommodate the connecting elements to the supporting structure, i.e. the screws or nails. The force transmission upon the action of a train is thus distributed over the entire length of the spacer 2 by these rails 27, so that it can be subjected to even greater loads. However, an all-metal design has the disadvantage mentioned at the outset of the transmission of heat or cold and sound, so that it should only be used in permissible cases; its main application is where the spacer 2 or the entire device runs horizontally and therefore the entire weight the disc 4 supported on the end of the spacer. A spacer made entirely of elastomer would bend, unless the weight of the washer 4 was absorbed by special support elements such as angle profile strips or tabs. However, since the washer 4 mostly rests on individual blocks (not shown) and therefore not directly on the spacer 2, it is sufficient to provide the all-metal design where these blocks (the so-called block) are located; in between is the cold and sound-absorbing elastomer version.

Particular attention must be paid to the formation of the side toothing 24. The elastomer material of the spacer 2, which is relatively soft against deflection, leads to the fact that the legs 21 carrying this toothing can be bent apart without great force. Although this facilitates the assembly of the cover profile strip 3 and is desirable in this regard. On the other hand, there is a risk that the legs can move outwards in the event of greater tensile forces which act on them through the foot of the cover profile strip 3, so that anchoring is no longer guaranteed. By a slight undercut, i.e. H. Inclination of the tooth areas transmitting the tensile force by approx. 150 compensates for the bending moment which acts on the legs 21 of the spacer 2. However, it is also possible to provide an additional toothing between the toothed ribs of the spacer and those of the cover profile strip instead of the inclined position, which also prevents the two parts from being compared. Such a toothing is shown in Figure 3; It can be seen here that each tooth of the toothing 24 first has a horizontal section 28 on its upper side and then a recess 29 projecting upwards.

Finally, the cover profile strip 3 should also be mentioned. As can be seen, it has the simplest shape of all three parts, namely essentially a mushroom shape, with two sealing lips 31 and an anchoring foot 32 with a toothing 33 which fits into the toothing 24 of the spacer 2; In order to facilitate driving in, as can be seen, the first teeth of the toothing 33 can be made less wide than the following ones. To save material, cavities, here two cavities 34, 35 can be provided; if necessary, they can also be filled with stiffening bars made of metal.

The toothing 33 is inserted into the toothing 24 only to the extent required by the respective thickness of the disk 4. This alone allows adaptation to the existing variety of discs. However, it is further improved by producing versions of different heights for the spacer 2 (and only for this). Profile strips 1 and 3 always remain unchanged. Thus, with a minimum of parts 1 -3 in stock, a complete response to all pane thicknesses is possible.

If there are a plurality of glass panes or facade elements 4 arranged next to or above one another in rows, each of which is surrounded by the device, there is a need for a crosswise arrangement of the latter, with numerous nodes. FIGS. 4 and 5 show how such a design is implemented. The flat strip 11 and the spacer 2 run through the device lying in the falling line or are connected at the end to the same parts of a new device. The support and sealing areas 12; they are removed at the point at which a, usually horizontal, device that crosses the first opens. The latter is connected to the former in such a way that the flat strips 11 result in a flat surface which forms the bottom of the channels 19 (FIG. 1). For this purpose, the spacer 2 of the horizontally extending device ends at the mouth. This means that water can also flow from this device into the one lying in the falling line and run there according to the arrows in FIG. 4, because in the falling line the spacers 2 also run through the full width of the channels mentioned, in particular through the portions of the flat strip 11 formed channel floors, which run continuously and seamlessly and thus waterproof. The abutting bearing and sealing areas 12 of the two devices are cut at an angle of 45 ° or generally in the bisector of the two devices, that is to say in a miter; the areas 12 of the horizontally extending devices, as can be seen from FIG. 4, are extended beyond the ends of the flat strips in order to be able to connect to the areas 12 of the device running in the falling line. The equipment can be cut to size and then glued on site; However, it is also possible to prefabricate nodes in the manufacturing plant, to which the devices connect their profile strips 1, 3, possibly also the spacers 2, on the end face (butt joint) and then glue them to them. In addition, it is also possible to manufacture a whole network of such devices in the factory by vulcanizing them together within a mold in the area of the node.

While the parts 1, 2 of the devices are brought together in the node as mentioned, the cover profile strips 3 are brought together according to FIG. H. with ends tapering at 45 ° or half the angle to the respective longitudinal axes, which are then also glued or vulcanized. Here, too, the connection can be made on the construction site or with prefabricated molded parts or a prefabricated network.

directions or their parts 1 -3 open at the top and bottom therefore depends on the inclination of those left in the fall line, so that they can drain, and also running equipment, accordingly the angle of inclination a small air circulation is possible. Above is to choose through hole 5.

a roof-shaped cover (not shown) prevents the entry of rainwater. For larger facilities s It was already mentioned at the beginning that the ventilation mentioned is no longer sufficient to achieve this, and that proper mounting and sealing not only requires additional ventilation arrangements, but also a particular shape of the facility. For this purpose, two holes 5 in the sealing lip - the choice of the most suitable material - a role 31 of the cover profile strip 3 which runs in the falling line, since both material and shape have to be inserted and then act in each hole. The device therefore consists of elastomer 5 and a tube 6 is inserted in such a way that it slants from the bore (for the spacer, as already mentioned, it can rise upwards if necessary. The height difference between which another material can also be used). As the inside of the pipe and the highest point of the mouth at moderate, one with a modulus of elasticity from the bore 5 should be at least 30 mm, around 30-60 N / mm2; the appropriate value will be determined in the event of driving rain entering the facility, d. H. in this case to avoid due to the expected loads and channels 19 (Figure 1). The inclination of the pipe of the construction details is fixed.
