Abstract

A skylight strip (1) for a roof (2) of an arcuate cross-section is arranged transversely with respect to the roof ridge and is formed by skylight panels (4) held in a frame (3). Said skylight strip (1) runs over the entire extent of the roof width or of the roof arc, with the result that its short sides or ends (5) help to form, or continue, the border (6) of the roof, as it were. The skylight panels (4) are configured, in the direction of the short dimension, that is to say in the direction of the roof ridge, with straight surface lines, that is to say they are not of an arched configuration, and are held, on the long borders, in a sealing clamping fit, with the result that heat movements are possible. A cutout, enclosed on all sides, within a roof, can thus be avoided because such a skylight strip (1) can be fitted between the borders of individual roof elements (13) in such a manner as to connect and span the same. <IMAGE>

Description

The invention relates to a roof with an arcuate cross section, with a daylight band, the long side of which consists of at least one light strip held in a frame over existing light strip the entire extent of the arched roof cross section is sufficient, the short side (s) of the light band forms the edge of the roof or continues and at least the edges running in the direction of the sheet the light plate are held in a sealing press fit.

Such a roof is already known from FR-A-1 564 025. Here it is provided that the daylight band of this known roof a double curvature, so no straight surface lines parallel to the ridge. This requires the prior art Daylight band from a variety of individual light panels to assemble that on the transverse edges by means of intermediate profiles connected and sealed against each other. This as Cross-section acting intermediate profiles hold the edges of each Light panels take their own weight and also form due to their protruding cross section, a cold bridge. In addition, they reduce the light output.

The task is therefore to create a roof with a daylight band to create the type mentioned, its manufacture, installation and assembly is inexpensive and simple and with which different Thermal movements, leaks and cold bridges simple way to be largely avoided.

The solution to this problem is that the light band in Direction of its short side or dimension and parallel to the Roof ridge has straight surface lines and that the license plate is in one piece or interrupted once and by an interruption overlapping cover or cover strip sealed and held is.

In this way, a light strip can be produced inexpensively, that can also be installed with relatively little effort. It no cutouts need to be made on the roof must be reinforced accordingly, but it can simply be the manufacture of the roof in the course of which a gap for the light band according to the invention are left, what gap this The light band closes after it has been installed. The sealing clamp seat the light panels within the support and support structure of this Light strip ensures tightness on the one hand and the possibility the thermal movements, on the other hand, which are unhindered by the entire large length of the daylight band, i.e. in the direction of the Course of the arch cross-section of the roof can take place. This is so possible above all because the daylight band is not also in its longitudinal direction within a roof cutout is limited, but can run out to the edge of the roof.

The in the ridge direction or in the direction of the short dimension of the The straight line design allows a material saving Manufacture of light panels compared to one in this direction too provided curvature. Since the light strip extends over the entire arc of the Roof cross-section, i.e. practically the entire width of the roof, there is nevertheless a good one inside such a building Illumination with daylight.

It is also advantageous that the light plates in one piece or only with a dimension corresponding to half the roof width are manufactured and are accordingly easy to transport, but in the assembly position from the ridge to the roof edge Extend warming and when cooling in reverse can contract, being transverse and as a cold bridge serving, increasing the assembly effort intermediate profiles - if necessary apart from a cover strip - be avoided.

It is especially cheap especially for transportation as well the installation of the light strip when the light panel on the roof ridge is interrupted. The result is practically two of the same size Light panels with a reduced compared to the roof width Dimension that facilitates transportation and the one already mentioned Permits thermal movement from the ridge.

In the course of the daylight band, especially in the area of a Interruption of the light panel or in the ridge area of the roof, can be arranged an openable flap, of whose Limiting on both sides of the light plates Run the roof edge. So in this way it is possible There is also a closable opening within the light band to be provided if there is an exit from the building onto the roof, but also ventilation or smoke extraction or one Smoke ventilation of the room below the roof is desirable. Through the aforementioned incorporation of the openable flap in the Strip of light in such a way that from the boundaries of the flap the light panels run towards the roof edge, they remain Advantages of a simple seal with possible at the same time Get thermal movements.

The clamp seat for the light panels can be on one opposite Roof level, frame following the roof curvature be provided on the top, in particular under Liner of a seal the cover plate can rest on which in turn on its edge from one it in turn from above acting clamping profile can be kept. It can so the light plate of the daylight band on one appropriate interlayer applied sealing and with a overlapping clamping profile can be fixed. This gives the Sealing and the desired press fit, if necessary allows slight thermal movements.

The clamping profile can be used with the frame be screwed and the clamping screws can laterally from the edge of the light plate or by in the direction of thermal expansion oriented elongated perforations of the light plate. Consequently the clamping screws can prevent any thermal movements do not hinder.

Immediately adjacent to the frame can be on the top of the Roof a sheet metal storage for one arranged underneath Insulation may be provided with a flange on the Top of the frame is enough, and the top of this Flange of sheet metal storage can be the requirement for the Light plate on the frame. Such a tin custody near the holding frame of a daylight strip with the corresponding Filling with an insulating material prevents the formation of Kondenzwasser especially in the frame area and above all on the inside. At the same time, this tin storage with the frame for the daylight band in the manner mentioned connected and thus results in a simple and inexpensive Construction.

An embodiment of the invention is of considerable importance can be that below the light plate (s) with Distance to each other in the direction of the short dimension of the Light panels extending cross beams are arranged in Normal position between yourself and the light plate a distance release the smaller than the elastic deformability of the Light panels under wind pressure, snow load or the like. So although the daylight band due to its extension A relatively large span across the entire roof vault loads cannot cause excessive deformation of the light panels, since these then from the cross beams be supported. This is especially true when short dimension of the daylight band relatively large, that is Light panels are relatively wide.

It is particularly cheap to secure against Gusts of wind and the like when in the clear distance between the cross member and the light plate at least one support buffer, in particular made of elastic material, is provided Expansion is smaller than that of the cross member. So you can possible dynamic loads on the light panels caused by Gusts of wind or the like can be caused dampened and a swinging of the light panels avoided will. In addition, static loads on the Light panels are introduced well into the cross member.

Over the length of the cross member or the width of the light strip can several between the cross member and the light band spaced support buffers, for example three or four support buffers. This keeps the distance largely preserved between cross member and light panel, nevertheless, there is good support for the light band reached the respective cross member.

The distance between the support buffers can be about the distance between the edge and the support buffer closest to it be. The support points are thus across the width of the Light strip evenly distributed on the cross member.

The cross members can be blunt on the frame for the light plate or attached via flanges, for example welded or be screwed. Because the frame has a certain vertical extent has enough between its frame legs Space for adequately dimensioned crossbeams that are in this Position in the desired way below the light panels are located.

Above the light band or the light panels can be used Distance to each other in the direction of the short dimension of the Continuous struts can be provided by the Have a distance smaller than the top of the light plate the elastic deformability under suction from wind or Storm is. This results in a mounting of the light panels even if one of the roofs due to wind and weather directed load on the relatively long roof direction Light panels are exercised. It is special advantageous that the light panels in the direction of their short Dimension or in their width have no curvature, so that correspondingly straight cross beams and struts use can find. This light strip can be correspondingly simple be protected against weather damage.

It is particularly advantageous if the struts are immediate run above the cross member so that the light panels held on both sides between cross member and strut or are supported. This may result in gusts of wind Vibrations occurring on the light panels from the outset well avoided or prevented. This can still be improved if between the strut and the light panels Support buffers or the like are arranged. Located the light plate between the support buffers on the one hand below the strut and on the other hand above the cross member, can absorb certain dynamic loads and such dynamic loads caused by certain movements yield, but without excessive vibrations or Deformations. Instead, the light panels are good fixed and supported.

As already mentioned, the can be in the arch direction of the roof running part of the holding frame on edges of metal or concrete existing roof elements tightly connected and be attached.

Overall, there is a light band for a high luminous efficiency, which is very simple in the course of an arcuate Roof can be integrated because there are no cutouts must be provided, but simply gaps between the respective roof elements by such a light strip can be filled in and bridged. Despite the big, over the entire roof width or the entire roof arch Trending light band can also cause problems Thermal movements are easily coped with.

In the embodiments described below parts that match their function are the same Reference numbers and reference numbers, even if in their Shape differ slightly from each other.

A daylight band designated as a whole serves for Attachment to a roof 2 with an arcuate cross-section, the long side of which is held in a frame 3 Light panels 4 existing light strip 1 across the roof ridge is arranged. It can be seen in Figures 1, 3 and 5 that on such a roof 2 possibly existing several times Light band 1 in each case over the entire extent of the Roof arch or the arched roof cross section is sufficient, that is, the short sides 5 of the light strip 1 each have the edge 6 form or continue the roof 1.

With reference to Fig.1, in particular also Fig.2 and Fig.5 and 6 you can see that the light band 1 in the direction of its short side or dimension and in the direction of the roof ridge has straight surface lines, i.e. daylight band 1 and its light panels 4 are curved only in the direction in which also describes the arch cross section of an arch, run in the transverse direction, however, i.e. in the direction of the Ridge of the roof straight. This results in very simple light panels 4, an inexpensive and economical overall solution.

At least the edges 7 in the direction of the arc Light plate 4 are in a manner to be described in held a tight, which is mainly based on of Figures 2 and 6 is clearly visible.

In Figure 3 it can be seen that the light plate 4 in particular on Roof ridge interrupted and by an interruption 8 comprehensive cover 9, namely a cover strip, sealed and held. In this case it is this Cover 9 opposite one below the light plates 4th extending cross member 10 with the aid of clamping screws 11 set so that the between the cover 9 and the Light plate 4 on the one hand and the light plate 4 and the Cross member 10 on the other hand located seals 12 firmly can be pressed. Starting from this interruption 8 each light panels 4 run to each other opposite edges 6 of the roof 2 down. However, if one Such roof 2 has no free edge 6, as it is between the several buildings according to FIGS. 1 and 5 is provided nevertheless the corresponding light plate the whole Follow roof cross-section.

The daylight band 1 runs over the entire Roof width up to the edge of the roof 6, so that a cutout can be avoided within the roof 2.

It can be clearly seen in FIGS. 1 and 5 that in each case Roof elements 13 lie next to one another and have interruptions, bridged and filled in by daylight strips 1 are. In the solution according to FIG. 1, the roof elements 13 trapezoidal sheets, which can also be seen more clearly in Fig.2 recognizes, while in the exemplary embodiment according to FIGS and 6 the roof elements 13 of approximately gutter-shaped Precast concrete parts are formed.

The already mentioned, shown in more detail in Fig. 2 and 6 Clamp fit for the edges of the light plates 4 is on the compared to the roof level, the roof curvature the following frame 3 is provided, according to its upper side 2 and 6 with the interposition of a seal 14 Light plate 4 rests, which in turn on its edge by one they in turn are held from above the clamping profile 15 is. This clamping profile 15 is in accordance with FIG. 2 with the frame 3 or one attached to it, to be described in more detail Sheet metal storage 16 screwed in use position. In Fig. 2 the corresponding clamping screw 17 is indicated schematically and extends laterally from the edge of the light plate 4. Possibly it could lead to more outside Light plates 4 also performed in elongated holes in the light plate 4 that could be oriented in the direction of thermal expansion or enough play for thermal expansion and thermal movement to have.

In this way, the light plate 4 on the frame 3 tight and yet kept so that different Coefficient of thermal expansion of the interconnected Materials do not cause difficulties.

Immediately adjacent to the frame 3 is the already mentioned sheet metal storage 16 on the top of the roof 2 provided that fixes an insulating material 18 in the frame area, so that condensation or condensation on the frame can be avoided. This sheet metal storage 16 is sufficient a flange 19 on the top of the frame 3 and the The top of this flange 19 forms the support according to FIG for the light plate 4 on the frame 3. The clamping profile 15 is with the help of the clamping screw 17 with this flange 19th connected.

This results in an expedient and simple construction to hold the light panels 4 on the frame 3 and at the same time also to determine the sheet metal storage 16 for the insulation 18th

Especially in Fig.3 you can see that below the light plate 4 at a distance from each other in the direction of the short dimension of the Light plates 4 extending cross members 10 are arranged, the cross member 10 running in the ridge area already in Connection with the cover strip 9 was mentioned. In Fig.3 and in Figures 2 and 6 you can see that between the respective cross member 10 and the light plate 4 in the normal position a distance is free that is smaller than the elastic Deformability of the light plate 4 under wind pressure, snow load or the like. Such loads on the light panels 4 can thus be taken up by the cross members 10, especially in the clear distance between the cross member 10 and the Light plate 4 support buffer 20 in particular made of elastic Material are provided, the expansion of which according to Fig.2 is smaller than that of the cross member 10. Rather are about that Length of the cross member 10 or the width of the light strip 1 several between the cross member 10 and the light plate 4 spaced-apart support buffers 20, in the exemplary embodiment 2, four such support buffers 20 are arranged. This leaves the light panels 4 enough space for dynamic movements with appropriate dynamic load, still supports the light plates 4 but at the same time under such loads well off, so that such loads and movements are dampened will.

The distance between the support buffers 20 is in accordance with Fig.2 approximately as large as the distance between the edge and the support buffer 20 closest to it, so that a uniform Distribution of the support points between light plate 4 and Cross member 10 and edge attachment of the light plate 4 on Frame 3 is reached.

The cross members 10 are on the frame 3 for the light panels 4th attached bluntly or via flanges, as is shown in FIGS. 2 and 6 is indicated.

Above the light band 1 and its light plates 4 are with Distance to each other in the direction of the short dimension of the Light strip 1 extending struts 21 provided by the Top of the light plates 4 according to Figure 2 and 6 a distance have less than the elastic deformability under Suction effect in wind or storm. Thus, the Light panels 4 also against the outside against such suction forces supported and held.

According to Figure 3, the struts 21 run directly above the Cross member 10 so that the light panels 4 each between Cross member 10 and strut 21 are held on both sides. Here are also between the strut 21 and the light plate 4th Support buffer 20 arranged, each with 2 and 3 the support buffers 20 between the light plate 4 and the cross member 10 can correspond. So there is a padded and damped clamping of the light plate 4 between cross members 10 and strut 21, so that static and also dynamic Loads of the light plate 4 well absorbed and to the Frame 3 and thus in the roof 2 can be derived.

The part of the holding frame that runs in the arch direction of the roof 3 can be on edges of metal or concrete Roof elements 13 be tightly connected and fastened, wherein Fig.2 a fastening to a metal roof and Fig.6 a such on a roof made of precast concrete 13 shows. In Fig.4 is indicated that the light band according to the invention even one Edge of a sheet metal roof element with one connect existing roof section from precast concrete parts and can bridge.

In any case, the creation of a cutout avoided within a closed roof skin and it can be exploited that such roofs 2 usually from several roof elements 13 running across the roof width consist. These only need to be so far apart to be arranged as it is of short dimension or width corresponds to the light band 1, so that the entire roof structure with a large, light-transmitting daylight band 1 can be carried out easily and yet stably, whereby the frame 3 running across the entire roof width through the the light plates 4 supporting cross member 10 additionally is braced.

The light panels 4 can also be in the area of the roof edge 6 3 in a clamped or sliding seat between the Be held frame 3 and a cover profile 22, wherein enough space for this within this bracket large thermal movements of the light plates 4 is provided.

In Fig. 7 it is shown that in the course of the daylight band 1 in the ridge area, an openable designated 23 as a whole Flap can be arranged, through which the light plate 4 is interrupted. In other words, from this openable Flap 23 and its lateral boundary 24 runs after the light plate 4 on both sides towards the roof edge. There the openable flap 23 interrupts the daylight band 1, it extends over its entire ridge direction Width. The connection to the limit of these openable Flap 23 can by an overlapping the light plate 4 here and possibly screwed and sealed profile respectively. The actual one, for example as Smoke vent openable closure flap 25 closed shown.

The daylight band 1 for roofs 2 with an arch Cross-section is arranged transversely to the ridge and made in one Frame 3 held light plates 4 formed. This band of light 1 runs over the entire extent of the roof width or of the roof arch, so that its short sides or ends 5 den To a certain extent form or continue edge 6 of the roof. The Light plates 4 are in the direction of the short dimension, that is in Direction of the ridge, with straight surface lines, so not arched design and on the long edges in one sealing clamp seat held so that thermal movements possible are. A cutout enclosed on all sides a roof can thus be avoided because of such Daylight band 1 between the edges of individual Roof elements 13, these connecting and bridging inserted can be.
