Description

The invention relates to a roof structure with inclined extending first profile rails and between them Profile rails used transparent plates that have a slope and their horizontal Bottom edges in a second horizontal profile rail are used, with two at each end the inclined first profile rails connected are.  

The profile rails of such a roof structure form a subdivided frame Structure in which the horizontal profile rails also the thrust of the transparent plates in Downhill direction.

Based on the terminology used in conventional, wooden roof structures, can inclined first profile rails also as "Rafters" and the horizontal second Profile rails are also referred to as "rungs".

When using a web made of plastic glass (acrylic glass) for the panels it was possible to insert these plates with a continuous length put that ver the length of both sides inclined corresponded to the first profile rails (rafters). The web glass plates made of plastic had with high strength a low weight, that too then no particular problems posed when the roof dimensions in downward direction, i.e. the length of the "Rafters", several meters, for example more than 3 m, cheat.

The subject of the invention is intended for the inert glazing of balconies and verandas (old building modernization) as well as for new buildings for the upper one Completion of bay windows, glass verandas, balconies and pavilions, as well as for the structured design of entire facade and roof structures when it comes to be  certain places to allow light to come in, such as. also for studio glazing and roof coverings close over stairwells and at galleries.

With the increasing surface area of the roof structures concerned, the desire went hand in hand with using instead of the plastic plates made of mineral glass, preferably plates made of insulating glass, in which two or more mineral glass panels are separated from one another by gaps and sealed together. In contrast to plastic sheet glass with a weight of about 5 to 7 kg / m ² , the insulating glass described above has a basis weight of 30 to 35 kg / m ² when using two mineral glass plates with a thickness of 6 to 8 mm, so that the maximum panel dimensions are limited for reasons of transport and handling during assembly.

One was therefore out of using insulating glass the above reasons forced the roof to divide areas also in the direction of the slope, and depending on the length of the inclined profile seemed (rafters) at least once. This subdivision happened through the horizontal already described Profile rails (rungs) over which the water is not necessary had to run away.

However, the sprouts mentioned have the unpleasant one Property, even after a downpour to form a kind of retention basin for the water  is limited to the sides by the rafters. The rainwater generally contains all the more more impurities, the lower the amount of rain is.

The accumulated amount of water and contaminants the smaller, the smaller the Roof slope at the point in question. By gradual evaporation of the water then remains the contaminants with clearly visible edges back; they are usually followed by Downpours no longer wash off and settle down only extraordinarily due to cleaning processes difficult to remove. The result is in review dirty edges clearly visible from below, their Strength and expansion increases over time, so that from time to time costly cleaning measures are to be carried out in the case of the metal profiles also no "sharp" cleaning agents are used can.

There have therefore been attempts in the past undertaken the amount of accumulated rain water by reducing the outside upper edges of the rungs beveled and with has its own slope. This allowed that The problem is mitigated but not eliminated, because the profile strength of the rung on the relevant one Can not place certain minimum dimensions below stride, and between the profile edge and the panels  There must also be a sealing profile on the top are made of an elastomeric material, so that the Height of the overflow edge above the top of the plate several Millimeters, generally 8 to 10 mm.

Attempts have also been made to include the plates (including Composite washers) butted directly without rungs to let and the joints with permanently elastic masses to seal. However, the durability is as low as the strength of the entire roof structure, since each lowest plates (not caught by rungs) Shear forces of the overlying plates must absorb.

The invention is therefore based on the object Roof construction of the type described at the beginning state at which any backflow or any Accumulation of water on the sloping transparent plates is excluded and thus the elimination of impurities and the training stubborn incrustations can be switched off.

The task is solved at Invention roof construction described above according to that in the horizontal rail (Rung) a drainage channel is arranged, the with the top of the above the rail located plate via at least one inlet opening communicates and the at least one outlet opening through which the drainage channel ent can be emptied.

Due to the specified profile training the At least put the top of the plate in question wisely into the drainage channel, so that no barrage, a retention basin or the same for the water is present. Consequently  there is also no deposit of residues Formation of incrustations etc. and the roof construction remains in the view from below their perfect appearance for a very long time.

The at least one inlet opening can by An series of slit-shaped inlet slots are formed by sections of elastomeric Sealing profiles are formed that are laying down the plate at intervals into the profile rail be set. The dimensions of the inlet openings or the gap width is expediently smaller chosen as the cross section of the drainage channel, so that coarse impurities such as leaves, branches etc. minor impurities that are retained the inlet openings can pass, but without further through the drainage canal (and nachge switched channels) can be dissipated.

It doesn't matter that with one heavy rain or if the Ent freezes water system most of the rain or Melting water runs over the profile rail. It is crucial that after completion no puddles of rain will hold that to the Ver can lead to dirt. This residual water can get in in any case through the inlet openings and the Ent drainage can be discharged.

It would be conceivable to include the drainage canal To provide outlet openings that the water over let the plate underneath run off. However, to gradually dry out the training Rivulets on the underlying plate  avoid, is pre according to the further invention suggest that the drainage channel in at least one of the inclined rails opens. In this way, the residual water is invisibly drained off leads, and it is only necessary that inclined running profile rails (rafters) with their lower ends in another drainage system to let it flow. It is particularly advantageous train the roof structure in such a way that the horizontal profile rail from a warm insulated composite profile, with

• a) a lower profile part, which is on its two longitudinal edge grooves for the form-fitting mounting of Has sealing profiles, which in turn as On able to serve for one plate each, as well as with
• b) an upper profile part that matches the lower profile part over at least a heat-insulating distance piece is connected to the drainage channel closes and in the downward direction below the Drainage channel has an extension on which up the drainage channel and the Ab covering the lower edge of the upper plate closing profile rail and down the one Holders covering the upper edge of the lower plate Profile rail is used, which extends over a another sealing profile on the plate edge supports.

Such a profile can consist of conventional profile parts be composed, as with an execution  example will be explained in more detail.

It is particularly important here that the to the horizontal profile rail (rung) abutting and plate edges running parallel to each other a sufficient amount of the end profile rail or are covered by the mounting rail, so that the interconnected edges of the insulating glass do not under any circumstances remove the UV radiation to be hit. This is particularly important because namely the processing guidelines of Glasher prescribe that the relevant disc or plate edges are protected accordingly have to.

To protect these edges, also against chemical ingress effect, it is particularly beneficial in addition To use adhesive strips and to attach them in such a way that the lower edge of each top plate over an adhesive tape with a wall surface of the Ent water channel is connected. This will make him is enough that the water over the bottom of the Plate is led away and not into the room can penetrate, in which the plate against the rung supports and in which the sensitive Ver binding points between the individual glass panels of the insulating glass.

It is optionally possible that the main planes of two to the horizontal profile rail from above and below abutting plates are in a common plane ( Fig. 1 and 2), or that the main planes run ver at an obtuse angle to each other ( Fig. 3rd ). The construction method described last is preferably used for pavilions or so-called galleries, the cross-section of which is in principle a polygon.

Exemplary embodiments of the subject matter of the invention are explained in more detail below with reference to FIGS. 1 to 4.

Show it:

Fig. 1 is a perspective view of a section of a roof construction with or without application to the drainage according to the invention,

Fig. 2 is a vertical section along the line II-II in Fig. 1 by a roof structure, in which the major planes of two of the same profile rail abutting plates of a common plane,

Fig. 3 is an illustration analogous to Fig. 2, but with the difference that the main planes of the two to the common rail on abutting plates at an obtuse angle to each other, and

Fig. 4 is a perspective view of the procedure when attaching an adhesive tape and its formation.

In Fig. 1, two first rails 1 and 2 are shown, which run in the downward direction and represent the so-called "rafters". These first profile rails run continuously within the section shown. Outside the cut-out, there are other first rails, all of which run parallel to each other. Between the first profile rails there are second profile rails 3 , 4 and 5 , the so-called "rungs", along a horizontal line.

Plates 6 and 7 are inserted between the above-mentioned rails, specifically the plates 6 are referred to as upper plates and the plates 7 are referred to as lower plates with respect to the second rails 3 to 5 . The gradient (in the direction of line II-II) is, for example, between 15 and 30 degrees.

In the middle of Fig. 1 it is shown what happens when the horizontal rail 4 together with the inclined rails 1 and 2 forms a retention basin for rainwater 8 , which is accumulated in a wedge shape. After this rainwater has evaporated, a dirt rim 9 usually remains.

Fig. 2 shows on the basis of the second profile rail 4 how it is possible to avoid the backwater of the rain water 8 and the dirt edge 9 in Fig. 1:
In the mounting rail 4 (and equally naturally in the mounting rails 3 and 5 ) there is an Ent watering channel 10 , which is connected to the top 11 of the upper half of the mounting rail 4 plate 6 via an inlet opening 12 in connection. One of the two outlet openings 10 a is located on the rear end of the profile rail 4 and is only shown in broken lines. The outlet opening 10 a leads into the inclined profile rail 1 , in which there is of course another, not shown, drainage channel.

As can be seen from FIG. 2, the inlet opening 12 is formed by a continuous parallel gap 4 over the length of the horizontal profile rail 4 , the gap width " s " of which is smaller than the width of the drainage channel 10 and the inlet 13 leading to this drainage channel . In this way it is ensured that coarser impurities are prevented from penetrating into the drainage channel 10 , but that smaller impurities which have penetrated, however, can flow off without obstruction.

Referring to FIG. 2, the horizontal rail 4 made of a heat-insulated composite profile. This is formed by a lower profile part 14 and an upper profile part 15 . The lower profile part 14 has on its two longitudinal edges 16 and 17 grooves 18 and 19 for the positive mounting of elastomeric sealing profiles 20 and 21 , which in turn serve as a support for each of the plates 6 and 7 .

The upper profile part 15 is connected to the lower profile part 14 via two heat-insulating spacers 22 and includes the drainage channel 10 . Furthermore, the upper profile part 15 has under half of the drainage channel 10 an extension 15 a , on the top of which a drainage channel 10 and the lower edge of the upper plate 6 is inserted over covering end profile rail 23 by a so-called clip connection. This upper end profile rail 23 has at its free end two unspecified projections that determine the dimension " s " of the inlet opening 12 and between which there is a groove 24 into which a further sealing profile, not shown here, can be used.

This sealing profile should (if present) not close the inlet opening 12 . Rather, the sealing profile is inserted in the form of short sections and at a distance from one another in the groove 24 , so that a sufficient fixing of the plate 6 is possible without unduly blocking the inlet opening 12 . As already said, it is sufficient that the residual water can drain off in a short time after the precipitation has ended.

In the extension 15 a a down the upper edge of the lower plate 7 covering retaining profile rail 25 is set by means of an analog clip connection. This retaining profile rail 25 contains a further sealing profile 26 in a corresponding groove, by means of which the retaining profile rail is supported in a well-sealing manner on the edge of the plate via the sealing profile.

From Fig. 2 it can also be seen that the lower edge of the upper plate 6 via an adhesive tape 27 with an inner wall surface of the drainage channel is connected ver. The adhesive strip 27 is covered over most of its width by the end profile rail 23 in order to protect it as much as possible from harmful UV radiation.

The wall thickness of the adhesive strip is exaggerated; in practice it does not appreciably narrow the dimension " s " of the inlet opening 12 . The rainwater runs off the top of the adhesive strip 27 without having the opportunity to penetrate into the space 28 below, in which the connection points of the plate 6 and spacer blocks 29 are located, which absorb the thrust of the upper plate 6 and are against corresponding, Support unspecified projections of the profile parts 14 and 15 without hindering the ventilation of the joints of the plates.

It can be seen from FIG. 2 that the backflow of rainwater 8 shown in FIG. 1 (middle) is not possible, at least not over a long period of time, but that rainwater that has accumulated for a short time from the top 11 of the plate 6 is unhindered via the inlet 13 can enter the drainage channel 10 and run from here.

In the embodiment in FIG. 3, the main planes of two plates 6 and 7 abutting the horizontal profile rail 4 a from above and below run at an obtuse angle to one another. The profile rail 4 a is correspondingly bent in cross section. In addition to Fig. 2, the following is also shown:

The lower profile part 14 a is formed subdivided, and in the region of its longitudinal edge 16 there is an insert profile 30 which in cross section has essentially the shape of an "L" and can be positively connected to the profile part 14 a . A corresponding groove for the sealing profile 20 is in the present case in the insert profile 30 , so that this is reliably held within the profile rail 4 a by the positional weight of the plate 6 . Details are shown in FIG. 4. The spacer blocks 29 are also present here.

As can be seen from Fig. 3, there is a side wall of the drainage channel 10 formed by the upstanding leg of the insert profile 30 , which is inserted or locked in a groove 14 b of the profile part 14 a . Due to the selected distances, the thermal resistance of the entire profile is maintained. In this case, the adhesive strip 27 is connected to the leg of the insert profile, the side wall of which simultaneously forms the one wall surface of the drainage channel 10 . In this way, the rainwater is conducted across the room 28 analogously to FIG. 2. The attachment of the adhesive strip 27 is also explained in more detail with reference to FIG. 4.

It is understood that in this case also the first profile rail 1 a has a correspondingly bent course.

A completely analog design also results for a further, not shown second profile rail, which represents the lower end of the entire roof construction. Unless you allow a free drain in a gutter, an analog profile rail can be seen at this point, in which only those parts are not available that allow the connection of a lower plate 7 .

The adhesive tape can be a self-adhesive metal foil or a self-adhesive ceramic fleece that ver in the specified manner with a protective film see is. Such durable tapes are commercially available today.

In Fig. 4, the insert profile 30 is shown, one leg 31 of which has the groove 18 for receiving the sealing profile 20 not shown ge, and noses 33 and 34 for a clip connection with the groove 14 b of the lower profile part 14 a ( Fig. 3).

In order to be able to attach the adhesive strip 27 easily, its protective film 27 a or 27 b is made divided in the region of the later kink (dividing line 27 c ). The attachment of the adhesive strip is then carried out with a not yet available profile rail 23 and plate 6 , by first removing the lower part 27 a of the protective film and the adhesive strip 27 on part of its width with the inner wall surface of the drainage channel, ie with the leg projecting upwards 32 , is connected. Then the dashed plate 6 is up (using spacer blocks 29 ), the upper part 27 b of the protective film is peeled off and the adhesive strip 27 by folding in the direction of arrow 35 also connected to the lower edge of the plate 6 , so that the In Fig. 3 shown rectangular formation of the adhesive strip 27 he gives. The adhesive coating is indicated by the dotted areas.
