Definitions

  • the present invention relates to a curtain which is suitable as splinter protection and has optical and thermal functionality.
  • Such hangings are needed, in particular, to protect buildings during terrorist attacks, for example. They are needed in all types of buildings, but especially in office buildings with large glass surfaces.
  • the object of the present invention is therefore to provide a building hangings, which u.a. a protection against high pressures or the associated consequences, in particular a splinter protection at the same time combined with optical and thermal functionality.
  • the present invention gives a completely different approach. She has recognized that it is already expedient if, instead of making the glass facades stable, certain components absorb the enormous energy by incurring irreversible damage for them. It is therefore allowed here that the - often large-scale - glazing is damaged. Then, however, the present invention intervenes by providing a curtain, which prevents any possible splinters from flying into the room, where they can injure persons.
  • these can be inner, lying between the panes or outside hangings, which also allow in the form of blinds or blinds sunscreen, glare, view and daylight.
  • These hangings can can be folded, fold away, wegfahrbar, rollable and the like.
  • Such a curtain can, if it is wegfahrbar and weather-resistant, also be used as outside stable, in particular wind stable, curtain. This makes it possible, for the first time, to install an external sunshade even for skyscrapers over 100 meters high, which was previously not possible due to the wind load. Such an external sun protection in high office buildings would offer a great energy saving potential in the current trend towards all-glass facades.
  • the curtain according to the invention thus already finances by saving operating costs and by a smaller air conditioning.
  • a leaner ventilation and air conditioning technology also has a lower space requirement for shafts and canals and a correspondingly larger rentable area on the profitability of the curtain according to the invention.
  • energy-saving regulations such as the European Union, the hangings invention allows a small revolution in high-rise building with all-glass facades.
  • the curtain according to the invention also achieves a high level of acceptance, since it provides the thermal and visual
  • the curtain can be formed either as a slat curtain / blind or as a roller blind.
  • a roller blind this can advantageously be produced from a flat fabric, knitted fabric and / or knitted fabric, this having as fiber components glass fibers, carbon fibers, aramid fibers or combinations thereof.
  • the fiber component can be metallized, plastic coated, for example, be vapor-deposited with aluminum.
  • Such a roller blind may be designed to be rollable and / or windable, but this is not required. There are also under certain circumstances variants advantageous in which the roller blind is static and remains in position permanently.
  • the fabric is metallized, it is possible in particular to meet the aesthetic requirements of the users, since this results in a nobler look.
  • a surface design that has a light color, for example, white improves the
  • Such a roller blind can then absorb a load, for example by pressure, three-dimensionally and also serves as splinter protection, since it can intercept splinters of the glass facade.
  • a load for example by pressure
  • three-dimensionally also serves as splinter protection
  • an internal assembly ie the building side to the Glass facade to perform.
  • fibers that can be stretched while absorbing energy, so that they absorb energy very well.
  • the curtain can also be advantageously carried out in the form of a lamellae / blind, i. a plurality of parallel juxtaposed rods, which are connected to each other, for example, via ribbons or ropes so that the individual rods hang horizontally in front of or behind the facade.
  • rods is meant here and below throughout every structure that has an elongated extent, as they have, for example, Venetian blind slats. Perpendicular to this longitudinal direction, such a rod may have a two-dimensional or even a three-dimensional structure / profile.
  • the rods can be designed as static structures or rotatable structures similar to a blind.
  • blind-like systems need not be gatherable, it is not necessary for the slats to be stackable. This then results in greater freedom in finding the shape for the profiles of the individual bars. Also for the roll-like, fabric-like systems, greater freedom in the formation of the fabric (for example, abrasion resistance or thickness of the fabric), if they do not have to be rollable or windable.
  • the lamellae can be made more stable by means of additional folds, edges, kinks and / or hollow chambers or similar structures.
  • the starting point for this are profiles such as, for example, the C-lamella, the Z-lamella, the Genius lamella and the all-metal store, or the lamella systems marketed under the trade name s_enn.
  • the metals used here are metals, such as aluminum sheet or stainless steel sheet, from which the lamellae can be produced by roll forming. In this case, it should be ensured that the corresponding structures are arranged and configured in such a way that the roll forming of the lamellae is not impeded thereby. However, other materials such as plastics, composites and the like are also possible.
  • Another way to improve the splinter protection or the pressure resistance is to reinforce the profiles in appropriate places or completely. This can be done, for example, by gluing with a film, which should preferably be adhered to those places that can be pasted before the roll forming process or even afterwards. This means that places that are flat prior to roll forming and after roll forming or that are only subjected to pressure during roll forming, such as, for example, the inside of curved or curved surfaces, can advantageously be covered.
  • the film or the fabric is only provided on the inside of the lamellae, ie on the building-side surface of the lamellae, and on the outside additionally advantageously provided with a reflective or highly reflective surface.
  • a reflective or highly reflective surface As such is suitable, for example, a diffuse-white painted or even a metallic highly reflective mirrored surface or a retrostructure. Also asymmetrically scattering surfaces can be used advantageously.
  • Such a variant is suitable for use as an external or internal protective curtain, which can optionally be activated.
  • Another way to stabilize the lamellae or rods is to use these as To make hollow profile, which is filled at least over part of its length or at least partially. This makes it possible to distribute a high initial pulse over the viscosity of the filling over a large area. Fillings with liquids or with a gel are particularly suitable for this purpose.
  • the profiles can also be filled with foam, for example using a lance.
  • a metal for example aluminum, steel or stainless steel, or even plastic.
  • Another way to increase the stability, the pressure insensitivity or the splinter protection of the bars, is to provide certain areas of the bars with predetermined kinks.
  • a pressure event such as an explosion
  • the predetermined bending points are activated and the curtain closes completely or partially.
  • the predetermined bending point can be made elastic, but advantageously also inelastic, so that the curtain is subsequently closed irreversibly.
  • the holder of the curtain according to the invention can be further formed according to the invention. Because usually such hangings are not performed so that the whole curtain provides sufficient resistance to the kinking of the blind. At most, the individual elements of the curtain are locked, such as in the all-metal store of the company Hüppebaumann. This is where the further development of the present invention is based, in which the traversability is completely dispensed with and the curtain is additionally braced at the top and bottom for locking in a lateral guide. This has the great advantage that then a deformation of the individual (elements, bars, slats, fabric) of the blind can be allowed, without risking that the curtain as a whole kinks away.
  • the bracing may be elastic or deformable, so that energy is absorbed by the bracing when an explosion event or a pressure wave occurs.
  • part of the energy of the pressure wave is absorbed both by the deformation of the individual elements of the suspension and the bracing.
  • Another possibility is to clamp the curtain in a relatively rigid frame or in a rigid frame, which is designed so stable that it does not deform. This makes it possible to prevent the side of the formation of slots in the deformed state.
  • the rigid frame itself may be stored again elastic or deformable.
  • the lateral fixing of the blind can be done with non-movable hangings with a terminal strip o- a nail bar.
  • a Venetian blind such as the C-lamella, the Z-lamella, the lamellae under the name Hüppelux Genius, Retroflex, Retrolux-0, Retrolux-U or all-metal store (the Company Hüppebaumann) are known, these are partially or completely covered with Kevlar or the like and not guided with ladder cords, but with loop cords. These are less easy to twist.
  • Loop cords should be stable (eg metal thread, kevlar, a fiber composite and the like).
  • the bottom rail should then be locked so that the curtain is firmly clamped.
  • the films used for bonding may be external, i. E. not in a hollow chamber, be applied. Particularly advantageous here is a wood look.
  • the film may advantageously be provided as the outermost layer with a real wood veneer.
  • the upper end does not lie further inward than the lower end, so that the inner side can not be hit by reflected light, that of the lower one Element (lamella or rod) is reflected upward. It is particularly preferred if the inner surface is vertical.
  • the bars have two surfaces, for example, a first and second surface, which are interconnected at their upper end.
  • the profile of the rod is in this case inverted V-shaped. This is also important if, for example, a triangular profile is produced with another third surface which adjoins the lower end of the first surface. If a further surface is provided, which adjoins the lower end of the second profile, then pentagonal and other profiles are possible if further surfaces are used.
  • the fourth surface can also have a protrude through the first to third surface formed triangle. In this case, the third surface may abut with its free end on the lower end of the second surface or on the lower end of the fourth surface or anywhere between the upper end of the second surface and the lower end of the fourth surface.

Abstract

La présente invention concerne un rideau qui convient comme protection contre les éclats et qui présente des fonctions optiques et thermiques. Ces rideaux sont nécessaires en particulier pour protéger par exemple des bâtiments d'attaques terroristes. Tout les types de bâtiment sont a priori concernés, mais en particulier des bâtiments de bureaux présentant de grandes surfaces vitrées. L'idée à la base de l'invention consiste à prévoir des rideaux qui reprennent la forte énergie dégagée par exemple par une explosion, tout en acceptant des dommages irréversibles aux rideaux. Il est important que le rideau reprenne l'énergie qu'il reçoit et entre autres empêche que des éclats éventuellement produits sur une façade vitrée soient projetés et blessent des personnes. Dans ce but, le rideau est configuré comme rideau intérieur ou rideau extérieur, et avantageusement comme volet à lamelles/jalousie ou également comme volet roulant.
