Abstract

A glass wall, which has panes held by essentially vertical profiled bars and horizontal profiled transoms, is to be constructed with low outlay safely and impermeably as well as in a corrosion-resistant and visually pleasing manner. To this end, the profiled bars and the profiled transoms are designed as extensively closed sheet-metal profiles which in each case have two half-shells which are profiled in an essentially U-shaped manner and are held, with legs facing one another, at a spacing in such a manner that their legs enclose slots of constant width. For reaching behind and holding the panes and for covering the slots, clamping strips and covering strips are constructed as one-piece, extensively closed sheet-metal profiles, the outer legs of which, which face one another in a common plane, enclose a slot of constant width. For sealing, there are placed over the free ends of the legs of the profiled bars, profiled transoms and of the clamping strips at least flexible sealing strips, the holding strips of which, which are applied in a U-shaped manner, reach behind the legs. The clamping strips are pressed against the profiled bars and the profiled transoms by means of clamping screws, the nuts of which are supported by means of projecting webs against the inner sides of the profiled legs of the clamping strips, so that the latter can be clamped securely without screws extending through them.

Description

Holding device for glazing that forms a glass wall

The invention relates to a holding device for by simple or Sealed glazing given multiple panes of mineral or organic glasses with an essentially vertical or

profile bars running along gradients and horizontal bars Profile rungs formed structure and with this connectable, intervening discs Clamping bars.

It is known to use glass walls or larger glass surfaces, e.g. of windows, Greenhouses or the like. To produce from vertical and horizontal rungs that For example. Are created from T-profile bars and are able to accommodate panes of glass that Secured by pieces of wire penetrating through holes and held by means of putty and are sealed. The possibilities of such profile steel gratings are, however, also limits the size of the slices to be introduced and the visual impression leaves something to be desired that such holding devices.

can hardly be used in today's buildings.

Plastic profiles are used in particular in window construction Holding devices are used that provide much better thermal insulation allow as steel profile constructions, and where used Panes are kept putty-free by sealing strips made of plastic profiles or strips bring about the desired seal, with, for example, locking, retaining or clamping bars or frames ensure mechanical hold. The minor mechanical Strength and high elasticity of such plastic profiles are also here the usable dimensions of the discs are limited, and by the larger discs The required dimensions of the plastic profiles can hardly be seen in the glass walls design in an appealing way. In addition, it is necessary with these known holding devices, to create this as a closed whole and to transport it to the place of use, so that additional difficulties arise especially with larger dimensions. It has also been proposed to use clamping strips when using metal profiles to brace with these by means of screws, but even with careful Sealing of the respective penetrated holes of the clamping bars resulted in additional Penetration routes for rain and other moisture, which reduce the already existing sensitivity to corrosion increased impermissibly.

The invention is therefore based on the object of providing a type corresponding To create a holding device for glass panes, but possibly also other panes, which the creation of larger glass and, if necessary, facade walls in optical pleasing shape, i.e. by means of relatively small profile dimensions Construction elements made possible with relatively little effort, in addition to the Constructive effort also the low to be driven for the transport and the assembly should be; In accordance with today's requirements, disks should be of different types Thickness, i.e. possibly multiple discs, and different materials as well can be used, as well as good thermal protection in addition to extensive corrosion protection Isolation should be secured.

This object is achieved by a holding device of the type described Type in which, according to the invention, the profile bars and the profile bars as largely closed sheet metal profiles are formed, each two essentially U-shaped have profiled half-shells with legs facing each other in such a way are kept at a constant distance that their legs slots of constant width limit by the clamping strips and / or cover strips as one-piece, largely closed sheet metal profiles are formed, in which two of the flanks in a common plane facing each other legs a slot constant Include width by placing the U-shaped over the free ends of the profile legs attached retaining strips are pushed by flexible sealing strips, and by the clamping bars against the profile bars and profile rungs by means of clamping screws are pressed, the nuts of which are less than the width of the column of the sheet metal profiles and by means of cantilevered webs against the inside of the profile legs prop up. This makes it possible for the screws to be inserted only by each other facing slots of the profiled sheets to use and on the moisture entry to completely dispense with holes in the clamping bars. At the same time a excellent thermal insulation possible, which is in the plane of the panes themselves is provided and is only bridged by the tensioning screws, even here by overlapping the sealing strips made of flexible plastic Basic insulation is achieved by means of interposed insulating plates can be further strengthened. Furthermore, there is the possibility of doing without special pre-assembly or preparatory work on the clamping bars, these in longitudinal position Slide the nuts over them and turn the nuts into theirs by about 900 to bring an operative position that enables clamping. At the same time, the Tension effect in the area of the clamping screws directly on the base surface of the clamping strips transferred, so that the profile of the cover strips from the full clamping forces is relieved. At the same time, the holding device can be made from prepared A few basic parts that can be assembled in a modular manner are just as easy transport as to assemble at the installation site.

Expedient developments and refinements of the invention are characterized in the subclaims.

In detail, the features of the invention are based on the following Description of exemplary embodiments in conjunction with these illustrative drawings explained. In this case: FIG. 1 shows a horizontal section through a vertical one Profile rod with inserted glazing and rear panes, Figures 2 to 5 exemplary profiles of clamping or cover strips, FIG. 6 a vertical cross section by a horizontal profile rung with panes of glazing and one of these holding support element, and FIG. 7 shows the front view at the connection point results in two profile rungs on a profile bar.

For the construction of glass walls, a holding device is used according to the invention used, which are made of vertical profile bars or bars running along gradients 1 exists, to which side profile bars are connected. The profile bars 1 as well the profile rungs are as not completely closed Rectangular tube sheet metal profiles are formed, each in the middle of their opposite one another Bases have a longitudinal slot so that these bases of two that run towards one another and enclose the slot between them Profile legs exist. The profile bars 1 and the profile rungs are expedient 25 made of sheet steel, possibly also stainless steel sheet, created in order to achieve high strength values the required high load capacity with relatively slim and small profile dimensions having sheet metal profiles. Corresponding to the mostly higher stress the substantially vertical profile bars 1 can do this with larger Profile height, possibly also greater thickness of the sheets forming the profiles, executed than the profile rungs. In the embodiment are profile bars and rungs formed with a substantially square profile; but also if for the profile bars If a more resilient profile is chosen, it is advisable to use this with the same The width of the profile is to be provided as the profile rungs.

In Fig. 1 the lying in a horizontal cross section is through a profile stand 1 of a holding device provided with glazing is shown.

The stand 1 is created from two half-shells 2, each made of a yoke 3 are formed on the legs bent at right angles on both sides Connect 4, the leg ends 5 of which are bent inwards. Are connected the half-shells 2 by means of a spacer sleeve which has shoulders screwed in on both sides, against the frustoconical shell-like inwardly pressed edge areas of holes the yokes 3 are placed. The above paragraphs approaches 8 of the spacer sleeve 6 are folded over the edge areas 7 like a tubular rivet, so that the two half-shells 3 are connected to each other at a fixed distance and between their bent leg ends 5 slots are formed over the length of the profile bar 1 a constant Have width.

The profile bar 1 is equipped with sealing strips 9, which are made of soft elastic Made of material and equipped with sealing lips and with a U-shaped attached retaining strips are provided. These sealing strips 9 are held, by slipping their retaining strips over the leg ends 5. Against the sealing strips 9 are then placed in the embodiment double panes 10 of a glazing, wherein in the area of the profile bar 1 facing double panes 10 by insulating strips 11 are separated from each other, which are expediently made of foamed plastic. This provides insulation that prevents convection in particular and provides mechanical insulation Separation of the double panes 10 is achieved.

The double panes lo are held by a likewise made of one Sheet metal profile formed clamping bar 12, which in principle of that shown in FIG corresponds to: close to a flat end face 13 parallel to the base face trapezoidally sloping flanks 14, their protruding edge areas as base strips 15 are bent into the common base plane so that a slot between them 3 remains, and the end regions of these base strips 15 are used as tension strips 16 beveled slightly inwards. As FIG. 1 shows, the base strips 15 are also the Clamping strip 12 is provided with sealing strips 17, which adjoin them in a U-shape Retaining strips encompass the tensioning strips 16 of the tensioning strip 12.

In the clamping bar 12 nuts 18 are inserted with the cantilevered Web 19 the; tension strips 16, if necessary also areas of Base strip 15 of clamping bar 12, reach from behind. There are holes in the nuts 18 the insulating strip 12 and clamps 21 screwed through clamping screws 20, the brackets 21 with projecting webs 22, the leg ends 5, if necessary also reach behind areas of the legs 4 of the profile bar l. This allows you to use a tool guided through the opposite slot of the profile bar 1 tighten the clamping screw 20 and thus the clamping bar 12 against the profile bar 1 brace that under firm and sealing application of the sealing lips of the sealing strip 9 and 17, the double panes 10 are safe and protected against the ingress of moisture being held.

The insertion of the nuts 18 and brackets 21 in the interiors of the Clamping bar 12 or the profile bar 1 can be pushed in from the side take place; However, it has proven useful to make the brackets or nuts so narrow that that their width falls below that of the slots formed in the sheet metal profiles.

In this case the nuts 18 or brackets can be rotated by 900 are inserted into the slots, and by turning 90 °, the cantilevered webs 19 and 22 brought over the leg ends 5 or tensioning strips 16. The position or the spacing of the tensioning screws 20 is penetrated by the Insulating strip 11 secured. Turning back the nuts 18 or brackets 21 the clamping position in the introductory position is avoided here because their cantilevered Web 19 and 22, respectively, the inwardly bent leg ends 5 or tensioning strips 16 reach behind. The inclination of the exciting surfaces of the webs is useful that of the legs ends 5 or tensioning strips 16 adapted so that a relatively large area Support on the retaining strips of the sealing strips 9 and 17 is achieved; different the cantilevered webs can depend on the representation selected in the drawing their free end still a parallel to the legs 4 or base strip 15 approach wear so that these are also used for tensioning.

As shown in FIGS. 3 to 5, clamping strips 12 cannot be used only use trapezoidal profiles. Thus, according to FIG. 3, rectangular profiles can be used be, whose end faces 23 in particular when forming the clamping strips from light metal or light metal alloys may have reinforcing profile webs 24, which in There is no case of forming from steel or stainless steel sheets. Other profile shapes too are possible, for example the partly rectangular, partly trapezoidal The profile of FIG. 4 or, for example, the semicircular one in FIG. 5.

It has proven useful to arrange the clamping screws 20 so that they each lie in a different horizontal plane than the spacer sleeves 6, so that the screw head is freely accessible through the opposite slot.

A vertical cross section through a horizontal profile rung 25 with the glazing held in place is shown in FIG. Here too, a Spacer sleeve 26 connected two profile shells so that their with their Leg ends inwardly bent legs include slots of constant width, and here, too, the profile legs of the profile rung 25 facing one another are and the clamping strip 29 equipped with sealing strips 27 and 28, which between the double panes 10 enclose. The weight of the double discs on top 10 is here received by a support element 31, which with a hook 32 the Legs of the overhead half-shell of the sheet metal profile of the profile rung 25 engages behind and with a support arm 33 on the leg end of the profile shell lying below supports. The weight of the double pane is essentially from the horizontal cantilevered support arm 34 of the support element 31 taken over. Are useful for even distribution of weight, possibly also to achieve a certain adhesion, between the double pane 10 and the support arm 34 washer strips 35 arranged. The gap to the double pane below is covered with insulating strips 36 filled in, which prevent undesired convection as well as heat conduction.

Here, too, the connection between the profile rung 25 and the they overlapping clamping bar 29 by clamping screws 20 in conjunction with nuts 18 and clips 21 of Fig. 1 causes; these connecting means, not shown however, they are not arranged in the levels in which the load-bearing elements are suspended, but in front of and behind them. On the other hand, these support elements allow any Support of the slices to be picked up; they can not just each in areas the end edges of the panes, but in any distribution below a pane be hooked.

The rear slots of the profile bars 1 and profile bars 25 can be covered by end strips 40 of FIG. 6, for example consist of relatively soft elastic plastic and as a full profile or thin-walled, inwardly open profile can be carried out, and on the leg ends of the sheet metal profiles and grip behind their end faces. On the other hand you can but also connecting strips 37 according to FIG. 1 are used, which are also Place on the leg ends and grip behind their end faces, but they are on both sides are equipped with such connecting elements, so that over a slot a sheet metal profile, a cover strip 38 can be attached, the base of which is the rear Legs of the sheet metal profile, for example. The profile bar l, with such a distance opposed to the fact that further cover plates 39 are held behind the actual glazing or the edge strips of a roller blind can also be guided. The one here any separate space formed behind the glazing is used here by Vented channels through the openings of the spacer sleeves 26 of the horizontal Profile rungs 25 are given.

These profile rungs can easily be placed in the area of spacer sleeves 6 of the profile bars 1 provide. Rods can be inserted into the spacer sleeves or the spacer sleeves have internal threads that accept screws Mistake. The spacer sleeves can also penetrate them Reinforcement bushings be equipped, which in turn are equipped with internal threads could be. These reinforcement bushings can also overlap the edge areas of the holes, and in this case the spacer sleeves can be used as pure spacer sleeves without any special approach be executed.

It has been shown to be essential that the profiles are identical whenever possible To use width to offer a closed appearance, like this for example is indicated in the view of FIG. Only the clamping bars are in this view 12 and 29 in conjunction with the sealing strips 17 and 28 connected to them recognize which the clamping strips seal against the double panes 10. So are the profile bar behind it and the profile bars as well as their sealing strips completely covered. The processing of the end areas of the clamping strips 29 and their sealing are simplified in that the clamping strips 29 cut normal to the profile axis and end pieces 30 made of plastic, for example, are inserted into the profile ends whose visible surfaces continue those of the cover strip, whose end faces accordingly be mitred, and with a shoulder in the profile interior of the tensioning strip 29, sealing it laterally, slide it in. Adjusting the load capacity Profiling can be done by a number of measures; it has proven itself here only measures to be taken that do not affect the width of the profile bars and profile rungs so that a complete covering through the Clamping bars remains secured.

The resilience of the profile bars can be determined by the selected material can be determined as well as by the sheet thickness.

Heavy-duty profile bars and profile bars are therefore created under Use of steel or stainless steel sheets, also within these categories Even more resilient materials can be used. Even heavy-duty ones Clamping bars can be made using stainless steel, possibly also other Steels. Often, however, less resilient materials are sufficient, for example light metal or light metal alloys. The use is also fundamental of plastics possible. The cover strips provided inside are not too great highly stressed, light metal and light metal alloys can be used here, if necessary plastics are also used, although steel and stainless steel profiles are also used here are usable. In general, the load capacity can also be determined by application Increase wider half profiles, which lead to profiles of greater depth. Basically one is also possible.

Increase in the profile width, if necessary while maintaining the Half-shells and extension of the spacer sleeves only. As essential to the choice the execution also have the corrosion resistance and the visual impression proven.

Sheet metal profiles made of stainless steel are considered to be corrosion-resistant; however, they can be coated with lacquer or plastic topcoats to influence their appearance be equipped. In the case of profiles made from sheet steel, it has been proven that to use galvanized material for reasons of corrosion resistance. the here with protected end faces, which are only for reasons of anodic protection show slight signs of corrosion, are turned inwards, so that these Cut surfaces do not appear visually. For visual reasons and if necessary For further protection, plastic or lacquer layers can be used, and also exists in principle the possibility of, for example, plastic-coated To process sheets and, if necessary, the cut surfaces placed inwards to protect further.

The inwardly curved end areas of the legs remove the Cut surfaces of direct observation, and at the same time they give nuts and Clamps also provide a defined hold against rotation. Resist when bracing it is an extension of the slot provided in the claimed area.

In the context of such a holding device, not only simple Panes of glass, double glazing or the like. -be held, it is also possible, for example. To include concrete slabs directly, to use wood or sheet metal plates, and ultimately even the use of is protected by the actual glazing Solar elements possible, which are arranged behind the actual panes and can be held by cover strips.

The one between such behind catching discs and the actual one Glazing caused by heat radiation heating of the air masses can be evacuated by an air circulation in the area of the profile bars whose spacers happened. These spacer sleeves can also be starting points for the connection be between profile bars and profile bars, and they can continue to be introduced inclined or diagonal stiffeners can be used. Here it is possible to use the Spacer sleeves or these reinforcing sockets with thread to accommodate screws equip; on the other hand, it is possible to pass screws through these spacer sleeves. Concrete parts can be included, which serve as base plates, through the change in direction can be brought about, the eaves are able to form, and through which further special functions can be achieved. It is also possible For example, to optionally cover glass panes by roller blinds carried by the profile rods or special shafts between or behind the glass panes to that can be used for heating, ventilation and removal of heated air. A wide variety of glass walls can thus easily be set up by means of the holding devices create the respective spatial, but also heating and ventilation Requirements are to be adapted, and their unified basic components are both easy are to be manufactured as well as transported and assembled. The visual too Execution can be adapted to the most varied of requirements, whereby, for example, Corrosion protection measures can be included. For example cover strips made of light metal or light metal alloys anodized and can be colored or covered as desired, stainless steel sheet metal profiles can be used with create the desired surface texture or with layers of plastic or lacquer cover, and the same is appropriate, including galvanizing, too possible for sheet steel. The various modifications that result here lead to the fact that the holding device is also versatile for different configurations of facades can be used.
