Definitions
- the invention relates to clamping surfaces for ceilings and walls that consist of one Panel grids are formed, and from frame covered with a film consist, the angular frame before covering in the tensioning plane have slightly curved struts against the tensioning direction and that The amount of protrusion increases from the corner points and in the middle is greatest between two corner points.
- a device and a device are known from US Pat. No. 2,381,029 Procedure for applying a preload to a tension cover for frames or panels known. The resulting deflection of the stenter or measures to avoid them are not included in the description.
- wall building boards are in particular Ceiling panels, known, which are formed by a polygonal frame.
- a fabric is stretched on the frame at least on one surface, each side of the frame elastic means, for example in the form of a spring leaf or steel wire, which on this one Can exert biasing force from the inside to the outside of the Frame is directed.
- This prestressing makes one appear Tension of the tensioned tissue counteracted and thus compensated.
- the elastic means used are immediately in the frame, for example with a rectangular cross section added so that the frame has a higher resistance to deformation compared to the tensile stresses that occur during assembly however, shown that the assembly of the individual frame elements together with the elastic means very time consuming and therefore is expensive.
- the technical problem underlying the invention is one To develop frame construction in which the covered frame in the desired Have side struts at an angle to each other without deflection.
- This Problem is solved in that the degree of protrusion is proportional to The amount of elastic preload of the film is and only through to the outside Pre-bent side struts can be achieved, so that after covering the side struts are straight.
- Ceiling or wall surfaces formed from such covered frames show one wrinkle-free surface that is uniformly thin and between the individual panel frames uniform joints without gaping deflection.
- an embodiment is particularly advantageous in which this different tensile strengths, i.e. the different restoring forces, are taken into account by the degree of curvature of the side struts.
- An embodiment is advantageous in which in each corner point of the frame Miter angle is formed without considering the bulge is determined and the mutual attachment of the side struts to the Miter joints are designed such that the relative movement of the side struts is not hindered in compensating for the bulge.
- the side struts of which should be perpendicular to each other Miter angles can be determined at 45 degrees.
- the side struts since the side struts are bulged on the outside, the side struts only meet theirs when assembled outermost edges on top of each other and gap increasingly to the inside apart as the side struts bulge outwards.
- the mutual attachment of the side struts to the miter joints in such a way be designed so that the relative movement of the side struts in balancing the Bulging is not hindered by the restoring forces of the film.
- the side struts closes then the gaping distance between the miter joints, so that these in Cover the strung state along the entire length.
- One embodiment is special advantageous, in which the film is translucent, but a refraction spectrum has, so that the light rays are diffusely deflected and on the Light output side no light source contours, only uniformly irradiated surfaces or areas are recognizable in which a center higher Radiance to the outside uniformly decreasing brightness is trained.
- Surfaces to be laminated can have any shape to have.
- the quadrangular surfaces can be squares, rectangles or trapezoidal surfaces, especially those to be suspended Blankets can also be regular hexagons.
- the shape of the frames for a grid-shaped panel covering are available in primarily quadrangular, i.e. predominantly rectangular or square Frame.
- the areas to be laminated can also be very well fill in completely with hexagonal base frames, then only on corresponding trapezoidal edge pieces are used have to. But also with differently shaped frames, ceiling and Fill the entire surface of the wall in a grid pattern.
- Fig. 1 are the outlines of a rectangular in schematic form Ralunens shown.
- the shape of the is with solid lines Side struts drawn before covering while using dashed lines Lines after the covering due to the restoring forces of the biased film resulting shape is indicated.
- the frame To after the Cover a rectangular frame with between the corner points To get straight side struts, the frame must originally the shape indicated by the solid lines exhibit.
- the bulge on the Narrow sides is significantly less than on the long sides. So that will indicated that the frame is constructed for covering with a film is in the longitudinal direction, that is, in the representation between the Narrow sides, has a lower elastic preload than in Transverse direction, that is, based on the frame in Fig. 1 in the Direction between the two long sides. It can be clearly seen that the respective bulge in the middle between the corner points of the Frame is largest.
- FIG. 2 shows a frame corner in an enlarged form, which is shown in FIG. 1 as detail II is unique.
- the side struts on the miter joints must be close together after covering the side struts of the frame in the unclamped state should be designed that they only touch at their extreme edges and from there to gaping apart inside. This is achieved in that the Miter angle when cutting the side struts without consideration the bulge can be determined. [in the illustrated embodiment does that mean that they are set at 45 degrees because the side struts of the Frame should be perpendicular to each other after covering. It is of course, that the mutual attachment of the side struts at the miter joints must be designed such that it is a Relative movement of the side struts when compensating for the bulge is not with special needs.
