Definitions

  • the invention relates to a light element with at least two translucent plates, between which there is a flat textile, and a method for producing this light element.
  • Such light elements with plates made of transparent plastic material are required and used to a large extent in or on the roofs of e.g. factory halls, factory buildings and also office buildings for lighting.
  • lighting elements can be provided not only on roofs, but also, for example, on the walls of a building or on free-standing supports.
  • Translucent sheets are usually designed as hollow-chamber elements, such as extruded multi-wall sheets, e.g. double-walled sheets.
  • the lighting in interiors should be glare-limited according to DIN 5034. It is therefore known to use opalized plastic for the translucent plates, which, however, entails an undesirable loss of light. Since, in accordance with DIN 4102, Part 7, elements of skylight structures must be prevented from falling down in the event of a fire, the EP 1332 261 B1 the use of a fabric-like material between two double-walled panels combined in a sandwich construction is proposed.
  • the fabric-like material is in the EP 1332 261 B1 loosely placed between the double wall sheets so that it is independent of changes in length of the double wall sheets, for example due to thermal expansion. Damage to the fabric-like material due to tensile stress can thus be avoided.
  • a rigid spacer is provided between the double wall plates.
  • the inserted tissue-like material then has a small distance of, for example, 0.5 to 2 mm from the double-walled panels and can move freely in the cavity thus formed between the upper and lower panels. If the panels of the light element expand as a result of the action of heat, the commercial material is not affected by it, it will neither clamped at its edges nor at any other point of the plates, so that no tensile stresses arise in the fabric-like material.
  • the object of the invention is therefore to provide a light element and a method for its production which is easy to produce and to ensure tightness over the service life of the light element.
  • an elastic sealing band is provided which is arranged along edges of the panels of the light element between these panels.
  • the distance between the at least two plates of the light element is adjusted by the elastic sealing tape arranged between these plates.
  • a sheet-like textile arranged between the respective plates is thinner than the spacing between the plates.
  • the elasticity of the sealing tape is chosen so that at least the weight of the plates arranged above it when the light element is arranged horizontally only causes compression of the sealing tape, which leads to a distance between the two plates that is greater than the thickness of the sheet-like textile .
  • a light element can be achieved with simple means that provides a cavity for jamming-free accommodation of the sheet-like textile through a spacing function of the sealing tape, the sealing tape at the same time being able to seal the cavity created between the plates.
  • an elastic sealing tape can be used as a sealing spacer and, in particular, the separate use of spacers with additional sealing means can be avoided. Due to the elasticity or elastic deformability of the sealing tape, it is possible to deform it in a defined manner in order to ensure a sealing function or to improve it compared to the solutions known from the prior art, while the sealing tape is adjustable to a defined thickness, whereby a defined height of the cavity can be achieved.
  • the light element according to the invention has a simplified structure, reduced production effort and thus production costs and improves the manageability of the light element, since an elastic spacer that seals itself is used.
  • one side of the elastic sealing tape is at least partially adhesively connected to one of the plates.
  • the sealing tape can thus be placed on the body and is thus fixed in a fixed relative position with respect to this plate. This improves the operability.
  • the sealing effect of the sealing tape can be improved by gluing.
  • the adhesive can counteract a recovery of the sealing tape. The forces required to maintain the elastic deformation of the sealing tape can therefore be reduced.
  • a double-sided adhesive elastic sealing tape is used, that is to say two sides of the elastic sealing tape are at least partially adhesively connected to both plates.
  • double-sided bonding it is possible with double-sided bonding to seal the light element particularly well and durably, for example on one end face, so that the penetration can be reliably prevented even if there is backwater when it rains.
  • gluing on both sides improves handling up to the final assembly of the light element.
  • the panels are fixed relative to one another by gluing the sealing tape and the panels are prevented from shifting in relation to one another, for example during transport to the construction site and during assembly.
  • the entire elastic sealing tape which is arranged between 2 adjacent plates of the light element, comprises a plurality of sealing tape sections, which are arranged between the plates, wherein between the several Joints resulting from sealing tape sections are sealingly joined, in particular glued.
  • This makes it possible to assemble the sealing tape from piecewise applied endless goods or piece goods and thus to use commercially available or standard goods. This lowers the costs, while virtually any shape of the sealing tape can be achieved with a minimum of variety of goods.
  • straight sealing tape sections can be provided at an angle to one another, so that a, for example, rectangular sealing tape can be achieved.
  • an adhesive tape is arranged around the edge of the at least two panels arranged on top of one another, so that the sealing tape arranged between these panels remains compressed until the elements are installed.
  • the sealing effect is improved by compressing the sealing tape.
  • the tendency of the sheet-like textile to fold in folds can be reduced by the height of the cavity being reduced in this way, which improves the manageability of the light element.
  • a protective film such as a hail protection film, can be attached to an outside of the light element by means of the adhesive tape.
  • the sealing tape By using the adhesive tape, that is to say a flexible means, to produce a sealing tape compression, the sealing tape can be compressed to a final distance dimension by a further clamping device for assembly without the adhesive tape having to be removed beforehand. A sufficient sealing effect is thus guaranteed at all times. If the sealing tape is compressed by attaching the adhesive tape directly after the production of the light element, the light element can also be handled in any position without the panels slipping.
  • the adhesive tape also serves as a transport and positional security device.
  • the light element consists of only 2 panels. What has been said applies analogously to the case that the light element comprises more than 2 plates.
  • FIGS 1a and 1b show the first embodiment of the invention in a cross section.
  • the light element 10 according to the invention of this exemplary embodiment comprises double-walled sheets 1, 2 as examples of translucent sheets 1, 2.
  • the sheets 1, 2 can be made, for example, of polycarbonate, PVC, PMMA, PET, glass or other materials. Polycarbonate is particularly preferably used because it has good mechanical properties, such as high strength and impact strength.
  • bodies of any desired shape, such as sheets or domes can of course be used; For example, simple multi-skin sheets, solid sheets or multi-wall sheets, but also thermal glasses.
  • the number of plates 1, 2 arranged next to or one above the other is also not limited, but rather dependent on the intended use, plate shape, and the like, and can be essentially any.
  • a spacing elastic sealing tape 4 creates a cavity H.
  • a flat textile 3 is arranged. Apart from securing against falling parts in the event of a fire, this is used in a known manner to, from the outside, in Fig. 1 from above, to change incident light, e.g. to scatter it, so that the in Fig. 1 light emitted on the lower side can be emitted glare-free or at least glare-limited. Incident infrared radiation can also be reduced.
  • a large number of sheet-like textiles 3 are suitable for this purpose.
  • Nonwovens and preferably woven fabrics for example made from glass fibers, have proven to be particularly suitable. In addition to good optical properties, these also have advantageous heat resistance, so that fire safety of the light element 10 can be ensured.
  • the sheet-like textile 3 is or is inserted into the cavity H.
  • the height of the cavity when the light element is not yet installed is 50% to 100% greater than the thickness of the elastic sealing tape 4 to be described. This allows further compression of the elastic sealing tape 4 when the light element is installed on the building.
  • the elastic sealing tape 4 is provided as an essentially solid mass, in contrast to sealing means which are applied in liquid or pasty form. This makes it possible, in a manner to be described in more detail, to elastically deform or compress the sealing tape 4 and thus to build up a sealing surface pressure when the plates 1, 2 and, by means of this, the sealing tape 4 are subjected to compressive force.
  • the light element with a correspondingly compressed by means of an adhesive tape 5 Sealing tape 4 is in Figure 1b shown.
  • a force is generated for this purpose, which moves the two plates towards one another.
  • the sealing tape is thus elastically deformed.
  • the adhesive tape is applied in such a way that it encompasses the edges of both panels 1, 2.
  • the mechanical strength of the adhesive tape prevents, after the plates 1, 2 have been loosened, the elastic sealing tape from relaxing beyond an amount predetermined by the adhesive tape.
  • the sealing tape 4 is, as in Fig. 2 shown by way of example, on the lower plate 1 along its edges R completely circumferential. In other words, the sealing tape 4 has no gaps.
  • a sealing tape 4 that is prefabricated and configured in the desired shape can be used, which reduces the outlay on assembly.
  • the required shape for producing the sealing tape 4 is punched out of a flat light element, for example.
  • the sealing tape 4 can alternatively be composed of individual sealing tape elements (sealing tape sections), as in FIG Figures 3a-c made clear. In this, joints of the sealing tape sections 4.1 and 4.2, which are designed to be geometrically different, are shown schematically as dashed lines.
  • the joints are joined without gaps, preferably by gluing.
  • welding the joint ends can also be advantageous, since this enables shorter processing cycle times and faster further processing.
  • Gluing in turn, is simple and can be carried out with few resources.
  • the glued or welded joint has sufficient tensile strength in the sealing tape plane, i.e. sufficient loading capacity when the sealing tape 4 is stretched transversely, so that it is compressed and thus deformed in the sealing tape 4 the joint does not come off or tear.
  • This can be achieved, for example, through a suitable choice of adhesive, a large amount of adhesive or even welding. It is preferred to choose the cold seam strength at least as high as the tensile strength of the sealing tape material.
  • the sealing tape 4 must be elastic so that it can be compressed in a defined manner and has a sealing effect.
  • (rubber) elastic materials in particular have proven to be advantageous.
  • a foam or cellular soft plastic is particularly preferably used.
  • the porosity of the material is sufficiently small to prevent water from creeping along an interface between the double-walled sheet 1, 2 and sealing tape 4, as well as preventing water from being sucked into the material.
  • an elastomer such as a (synthetic) rubber known per se, meets these requirements.
  • the sealing tape 4 is used in the in Fig. 1a
  • the horizontal light element 10 shown is loaded by a weight of the upper plate 2 (in the case of more than 2 plates, by all of the plates arranged above).
  • the sealing tape 4 is deformed according to its elastic deformability; so compressed by the acting pressure force in the thickness or height direction, which leads to an expansion in the transverse direction or in the plane.
  • the sheet-like textile 3 should have the possibility of deforming independently of the plates 1, 2 (for example through thermal expansion), or of not having any force-locking contact with the plates 1, 2.
  • the sealing tape 4 must have such a low elasticity or so low elastic deformability that it is deformed by the load with the weight of the upper plate 2 to such an extent that the distance between the plates 1, 2 ensured by the sealing tape 4 is greater than the thickness of the fabric 3.
  • the sealing tape 4 must have such a high elastic deformability that it can be compressed with such little force to the desired thickness, which can be applied and held by an adhesive tape 5 or a clamping device 20 without damaging the light element 10 .
  • the thickness of the sealing tape 4 when compressed to 50 ... 67% of its original thickness or height is almost the same as that of the sheet-like textile 3. Tests have shown that the sealing tape is compressed to about 50 ... 67% of its thickness that the sealing effect of the sealing tape is optimal in many cases.
  • other compression values are also suitable, depending on the material of the sealing tape.
  • sealing tape 4 is arranged only on the edges of two plates 1, 2 arranged parallel to one another.
  • further sealing tape sections can be provided to subdivide the entire surface.
  • the relevant embodiment, in which webs are provided in the interior of the sealing tape 4 surrounding the plate, are also conceivable. Such webs are to be provided in particular if a screw connection has to be provided for fixing the light element in the interior of the surface.
  • the elastic sealing tape 4 is placed with its underside on the upward-facing surface of the lower plate 1.
  • the sealing tape 4 can be partially or completely glued to the plate on one side, for example in the area in which backwater is to be expected with an inclined installation in a U-shaped rail or in which backwater is to be expected due to a particularly exposed location.
  • the sealing effect can be further increased by this bonding. It is thereby also possible to fix the sealing tape 4 on the lower plate 1 so that it holds a certain position by no longer slipping. It should be noted that when using a plate 1, 2 made of polycarbonate, an appropriately compatible adhesive must be used.
  • gluing is also understood to mean any other suitable form of adhesive connection.
  • the surface of the sealing tape 4 can also be activated thermally or chemically, e.g. melted or loosened, in order to achieve an adhesive connection with a plate 1, 2.
  • Pretreatments of the plate 1, 2 and / or the sealing tape 4 are also conceivable, which increase the wettability, e.g. by means of plasma treatment or corona treatment.
  • the sealing band 4 of the light element 10 is preferably provided at a distance on all sides from the edges R of the plates 1, 2, as in FIG Fig. 1a shown, so that the sealing tape 4, which is deformable by compression, does not protrude beyond the edge of the double-walled plate 3 when it extends transversely. Damage to the sealing tape 4 when handling the light element 10 can thus be avoided.
  • a lateral protective device is preferably provided to protect the sealing tape 4; this can be formed, for example, by the adhesive tape 5.
  • the fabric 3 is placed in an area F delimited by the sealing tape 4 on the lower double-walled plate 1, the area F corresponding to the cavity H of the finished light element 10.
  • the fabric 3 is preferably dimensioned such that it takes up a distance of 0.5 to 2 mm on all sides from the sealing tape 4 so that the fabric 3 is not pinched by compression when the sealing tape 4 expands transversely. If, however, a sealing tape 4 is used, the material of which has a small transverse extent, the fabric 3 can also be provided flush with the sealing tape 4 for optimal coverage of the surface F.
  • the optical properties of the textile 3 can be guaranteed uniformly over the entire surface F in both cases.
  • the fixing of the textile 3 takes place in a known manner as in the case of a light element, the plates 1, 2 of which are connected by means of rigid spacers.
  • the top plate 2 is placed on the sealing tape 4.
  • an at least partially adhesive connection can be advantageous here.
  • the upper plate 2 is preferably arranged flush with the lower one. However, should, for example, a Saddle construction are made possible, a parallel alignment of side surfaces of the plates 1 is sufficient.
  • the adhesive tape 5 is attached to the side areas of the plates 1, 2. This is attached to the plates 1, 2 under prestress in such a way that the sealing tape 4 is compressed to the second thickness.
  • the adhesive tape 5 is shown schematically in FIG Figure 1b shown.
  • the adhesive tape 5 is first attached to an outside of the upper plate 2, the light element 10 is pre-compressed to the desired size by means of a press, manually or by pulling the partially attached adhesive tape 5 and finally attached to the lower plate 1 in this state.
  • the adhesive tape 5 is preferably an aluminum adhesive tape 5 with sufficient tensile strength. If a press is used to apply the adhesive tape 5, which presses the two plates 1, 2 against one another, the adhesive tape 5 can of course also be fastened to the lower plate 1 first.
  • the adhesive tape 5 By increasing the compression by means of the adhesive tape 5, preferably immediately after the production of the light element, it can be ensured that the plates 1, 2 are kept secured against slipping even without the use of adhesive between the sealing tape 4 and the plates 1, 2. As explained, the sealing function of the sealing tape 4 is increased by the compression. If adhesive is applied between the sealing tape 4 and the plates 1, 2, this securing by the adhesive tape 5 means that the adhesive layer can harden or develop adhesive strength in a defined relative position of the plates 1, 2 to one another.
  • a hail or transport protection film can also be attached to the outer sides of the plates 1, 2 and fixed by means of the adhesive tape 5. This saves additional, separate fastening means for attaching such an optional protective film.
  • the adhesive tape 5 serves to protect the side areas of the light element 10 against external influences during transport, handling and storage, since the particularly sensitive edges of the light element 10 are shielded from impacts or sharp objects, for example. Damage to the light element 10 can thus be effectively prevented.
  • the transportable light element 10 produced in this way can now be handled and stored in any position.
  • the cavity H, in which the fabric (textile) 3 is located has been made smaller by the compression in the vertical or normal direction.
  • the sealing tape 4 is reduced to the second thickness by means of this compression, which almost corresponds to that of the fabric 3, that is to say is only insignificantly greater. This can also effectively prevent the fabric 3 from slipping due to a change in the position of the light element 10, since it has no possibility of wrinkling or creasing due to the spatial restriction.
  • a third distance to be finally set can be provided between the two plates 1, 2, but this is only achieved during final assembly, in which the fastening to the building causes further compression of the elastic sealing tape 4 and which is described below.
