Definitions

  • the invention relates to a roller shutter slat according to the preamble of claim 1.
  • plastic ones are cheaper, lighter and heat-insulating, but also have disadvantages. They are relatively less stiff against wind pressure and suction; furthermore, when coloring the plastic fes are taken into account that this may heat up so much under sunlight that the plastic deforms.
  • the invention is therefore based on the object, the known.
  • a roller shutter rod is therefore sought which has at least the bending stiffness of the generic roller shutter rod, but at the same time has a heat-insulating effect which is equivalent to that of a roller shutter rod formed only from a plastic hollow profile rod.
  • the weather-side hollow profile wall but also the building-side hollow profile wall is stiffened with a metal layer, and the webs connecting these two walls are designed so that they are able to transmit longitudinal shear stresses.
  • the entire roller shutter slat is thus designed as a hollow beam, the upper and lower chords of which are covered by a metal layer high tensile strength is formed, which is significantly higher than that of the plastic of the hollow profile.
  • the plastic of the webs is suitable, however, for absorbing the shear stresses that occur when the roller shutter rod is loaded, the webs possibly being thickened without a relatively large amount of material because they are relatively short.
  • roller shutter slat Another feature of the roller shutter slat according to the invention is that the additional metal layer is not attached to the inside of the profile wall on the inside of the building, as it should have been, but on the inside. This measure ensures that when the roller shutter is rolled up, there is no metal layer on the metal layer, so that the risk of scratching the metal surface on the weather side is greatly reduced. This metal surface can thus always retain its heat-reflecting and also heat radiation-preventing effect.
  • the additional metal layer located inside the profile also has at least one surface which is designed to reflect the heat radiation or to prevent the heat radiation. Since none of the surfaces of the additional metal layer is accessible, each of these surfaces can have its state Maintained over the full period of use of the roller shutter slat.
  • the metal surface that adheres to the inside of the building and adheres to the profile wall has a certain reflective effect on heat radiation from the building, while the other surface, if it is rough-rolled, reduces the emission of heat radiation.
  • the additional metal layer thus acts as a heat radiation barrier and not only preserves the insulating effect of the plastic hollow profile rod, but also improves it.
  • a metal section is no longer required, which, like the known roller shutter bar, extends between the inside and outside of the building, so that the two metal layers essentially only run in areas in which approximately the same temperature during heat transfer prevails, so that the two metal layers in turn do not transmit heat.
  • the two metal layers additionally have a minimum distance from one another which is approximately equal to the smallest thickness of the roller shutter rod. So it is possible as to enhance the engagement strip of ROL l adenstabes also zoom pull the weather exposed metal layer, but as long as this always maintains the stated minimum distance from the building inside metal layer of the same or adjacent roller shutter slat, the insulating effect of the roller shutter slat according to the invention is always in essentially maintained.
  • the two metal layers preferably coated with adhesive on the side facing the plastic, are preferably extrusion-coated with the hollow profile, the two - optionally preformed - metal strips entering an extrusion die. It must be ensured that the shear stress-transmitting connection between the latter and the webs is ensured in the area of the additional metal layer.
  • this additional metal layer is formed by a sheet metal strip which is perforated in the region of the connection of the webs to the profile wall on the building side.
  • the webs are thus in a direct material connection with the building-side profile wall, and they bridge over the sheet metal sections remaining between the perforations of the sheet metal strip.
  • the shear stress-transmitting connection between M e-tallstMail and lands achieved through the integral connection between the metal strip and profile wall 'as well as by direct integral connection between the section wall and the web.
  • the perforation in the metal strip is formed by a series of closely spaced elongated holes. The sheet metal sections between two successive elongated holes can be dimensioned so narrow that ultimately only the correct entry of the perforated sheet metal strip into the extrusion die is ensured.
  • an unperforated sheet metal strip which - coated on both sides with an adhesion promoter - is introduced into the extrusion mold and is connected on the one hand to the profile wall on the building side and on the other hand to the webs in each case in a cohesive and shear stress-transmitting manner.
  • the part of the web adjacent to the metal layer mentioned can advantageously be formed into a wide base, the integral connection of which to the metal layer then ensures the correct transmission of shear stresses.
  • a number of narrower individual sheet metal strips which each adhere to the profile wall surface between two adjacent webs, can also be formed instead of a sheet metal strip that extends across the profile height. Due to the integral connection with the profile wall on the building side, these narrow sheet metal strips lying next to one another behave overall like a continuous sheet metal strip. However, since those areas between the adjacent sheet metal partial strips in which the webs are connected to the profile wall on the building side are omitted, this connection, which is important for the bending strength of the roller shutter slat according to the invention, can take place without any problems.
  • the sheet metal partial strip preferably has at least one guide fold by means of which it can run precisely into the extrusion mold, so that a disturbance in the important connection area between the webs and the profile wall is eliminated.
  • a fold acts as a stiffening of the respective sheet metal partial strip, but practically does not impair the heat-insulating effect of the roller shutter slat according to the invention because of its low height.
  • the metal layers are formed from thin aluminum sheet, the thickness of which is preferably approximately 0.2 mm.
  • a sheet of such low thickness is already sufficient to give it the multiple bending strength of an uncoated hollow plastic profile bar.
  • the use of a thin aluminum sheet has the advantage that it is pressed in flat contact with the respective wall of the extrusion nozzle during the extrusion process, so that the measuring stability of the roller shutter rod is ensured.
  • a decoration applied to a visible surface of such a metal surface survives the extrusion process.
  • the shaping of the metal layer can take place during the extrusion process, the respective metal layer being preformed by means of an appropriately designed inlet and then being finished during the extrusion process in the manner described above.
  • the outside of the weather-side metal layer is provided with a coating or a surface treatment layer which promotes or preserves the effect of this surface which reflects or reduces heat radiation.
  • a coating or a surface treatment layer which promotes or preserves the effect of this surface which reflects or reduces heat radiation.
  • an oxidation treatment is applied, which not only serves the coloring, but also provides a thin, but very hard oxide layer that maintains the roll-smoothed condition of the treated surface over a long period of use.
  • the ends of the roller shutter bar are closed, in particular by means of a foam made of rigid foam.
  • This end closure not only prevents heat loss due to the outflow of heated air from the inside of the roller shutter slat, but also forms an end stiffening of the roller shutter slat in those areas in which this slat is guided and in which the counteracting forces opposing it are thus introduced into the roller shutter slat when it bends.
  • deposits on the hollow chamber-side metal surface are largely prevented by dirt particles, which impair the radiation properties.
  • a roller shutter slat according to the invention is shown in cross section.
  • This roller shutter rod is formed by a plastic hollow profile rod 1, which has two slightly curved, essentially parallel outer walls, namely a weather wall 2 and a building wall 9, which are connected to each other at their ends by an outer web 3 to form a closed box profile.
  • the interior is divided into three superimposed interior spaces, which extend in the longitudinal direction of the hollow plastic profile rod 1, from which the middle to the two outer ones is separated by an intermediate web 4, while the two outer ones are separated from the outside by one of the mentioned outer webs 3 .
  • a cross-section-shaped hooking strip 7 is formed on the box section described, which has light and ventilation holes 11 in the area of its connection with the closed box section.
  • a terminal strip 8 which is also hook-shaped in cross section, is formed, which is complementary to the hanging strip 7 in such a way that two successive plastic hollow profile rods with their strips 7, 8 can be inserted one into the other, an articulated connection being produced between these two plastic hollow profile rods is.
  • the outside of the weather wall 2 is cohesive, i.e. firmly adhering, with a metal weather situation 5 on an aluminum sheet of e.g. 0.3 mm thick coated, which extends to the attack bar beyond the weather wall 2 and is a small distance to the neighboring outdoor day 3.
  • the weather situation 5 extends beyond the light and ventilation holes 11 and ends in the area of the hanging strip 7 on its weather side.
  • an inner layer 6 made of aluminum sheet, for example 0.3 mm thick is applied on the inside, ie the side of the building wall 9 facing the weather wall 2, an inner layer 6 made of aluminum sheet, for example 0.3 mm thick, is applied.
  • the inner metal layer 6 in the area of the intermediate webs 4 has two rows of elongated holes 10 each extending in the longitudinal direction of the roller shutter bar, which are adjacent to one another by a certain distance. These long holes are penetrated by the foot of the adjacent intermediate webs 4, which enter into a shear stress-transmitting or shear-resistant connection with the building wall 9.
  • the shear-resistant connection between the building wall 9 and intermediate webs 4 is established by mediation of the inner layer 6:
  • This inner layer 6 is, as in the case of the object of FIG on. Instead, the adjacent area of the respective intermediate web 4 is designed as a foot 12, which in turn is in a material connection with the adjacent inner layer 6.
  • the contact surface of the foot 12 is selected so that the desired shear strength is guaranteed.
  • the hanging bar 7 is not designed as part of the plastic hollow profile rod 1, but rather as part of the weather situation 5, which is designed for this purpose into a hook-like bent fold.
  • FIGS. 1 and 3 show a further embodiment of the roller shutter bar.
  • the weather situation 5 does not extend beyond the light and ventilation holes 11, as in the subject of FIGS. 1 and 3, but only up to just below them.
  • the hanging bar 7 is designed as an unreinforced extension of the plastic hollow profile rod 1.
  • partial sheet metal strips 13, 14 are provided, which only extend to the area of the transition between the respective intermediate web 4 and the building wall 9, in order not to disturb this shear stress-transmitting transition.
  • the upper part of the strip 13 in the drawing has a fold 15 in the area of its center, which serves to guide the part strip 13 when it enters an extrusion mold and at the same time also serves to stiffen it.
  • the partial strip 14 also shown in FIG. 4 does not have such a fold.
