Abstract

An insulating shaping surface element, which is pneumatically controlled, can serve as an enclosure in building, or in other ways. A two-layered surface structure system is held on two axes, so as to surround the area, by fixtures between fixed or flexible stretching frames. Two or more reinforced or simple foil sheets are inlaid between the two structures, joined together so as to be gastight. These are pressed against the structures by gas pressure exceeding atmospheric pressure, stretching and stabilising them, and deforming them outwards according to plan. A stable, enclosed hollow unit is produced.

Description

Pneumatically controllable, isolating form and surface element

The invention relates to a pneumatic construction Use as a choice of dynamically controllable or statically static form and surface element for the main use in construction as room-covering, rauntetlendes, room-enclosing Component, but also suitable for other applications than in construction.

Pneumatic constructions have always existed, i.e. with a gaseous medium stabilized envelopes, in construction as static, via pressure-controlled single-chamber elements with a static envelope, their exclusive task represents the covering of rooms and thus protection against the effects of the weather.

The invention is based on the object of protecting against the elements also through dynamic regulation of several superimposed gas layers a body with continuously variable functions in the areas of the tennis niche, to build up sound and radiation-related Wtrkungswelsen to meet needs Control interactions from the surrounding and enclosed atmosphere and to be able to use, e.g. in the case of a transparent or translucent design, the simultaneous Use of energy in the sense of energy collection and storage.

According to the invention, this object is achieved as follows: The construction consists of two planar structures arranged parallel to each other, which between fixed or flexible chipboard frame (e.g.

Ropes) must be fixed. This tenter frame can be used individually or be repetitive in one or two axes.

The planar structure can be made of parallel or asymmetrical to each other orderly and / or intersecting, network-forming setl, belt, Band or framework exist. The single framed segment of the wing structure can be between fixed, between tense or between alternately fixed and tensioned to each other arranged frame parts are fixed.

The parts framing the planar structure are then removed the forces triggering the clamping by a clamped or unclamped frame bearing one or more segments on the load-bearing delimiting or dividing lines including total surface structure.

Between the two-ply, which are arranged vertically parallel to each other Planar structures are formed following webs along their boundary edges, which one or more, single or multi-layered connections by means of fixed or separable connections connected opaque, translucent or transparent, reinforced, duplicated or simple Connect the foils to the frame all the way around.

The membranes enclosed between the two-dimensional structures are by means of a manual or program-controlled device that removes gas pressure In a gaseous medium, press apart or adjust the height to one another.

Here, the membranes initially lying on the surface structures close to this and deform the surface structure depending on the generated overpressure compared to the ambient atmospheric pressure, the two limiting wove Remove planar structures from each other depending on the pressure and thus create a constructive one form limited hollow bodies connected by two flat structures in the frame.

The above-described membranes, which body the pressure chamber of the hollow enclose, are held down due to the framed planar structure that bounds them and thus with regard to their strain and pressure-dependent deformation and tension determined by the planar structure.

As a result, such a hollow body is from the disc to the full Krels in a cross-section through the wing structure.

The membranes are with regard to their pressure and suction stress due to the multi-part one or two-axis decomposition of your area depending on their mater 1 al characteristic values according to the pre-determined load approximations by the to select the appropriate design of the planar structure to be determined.

The membranes that connect the interior pressure space to the surrounding atmosphere limit, are as a whole vorbestimpar, deformable division, not stressed, which Membranes. Sle dlenden exclusively as delimiting the pressure space, the tense Closing levels adjacent to the planar structures.

One or more dreads can be read between the delimitation membranes assigned in parallel, connected to the jetty or with the limiting diaphragms or

be stored with similar connected membranes.

The cavity given by the delimitation membranes can pass through the inserted dividing membranes in a multiple vertically layered number of Cavities are broken down while maintaining the body shape. The resulting horizontal, follen-limited gas slaughtering can be done by means of a valve-controlled gas pressure system In manual or program-controlled regulation 1 tion with regard to their distance be adjusted among each other and between the limiting membranes. This is done by exchanging volume within the delimited total pressure hull.

This means that all of them can be stored between the limiting membranes Tel lungsmembranen a number of additional gas layer spaces corresponding to their number form. Furthermore, sle can against the limiting membranes and against each other can be duplicated at will. Likewise, depending on the number of divisions, form several low-convection, thermally insulating layers that are pressure and spaced according to the appropriate Ness and control technology as gas flow spaces be used.

The construction described in this way can be handled either in a dormant or dynamic manner Shape and surface element with pressure-dependent and / or regulating shaping characteristics should, among other things, in the areas of the surrounding area, the room-covering and the room-dividing construction methods find their use.

In the transparent and limited also in the translucent version the element has energy-reducing and energy-retaining functions. Follow selnes Structure with which, not stretched membranes, it has a sound-limiting and noise reducing for room and structure-borne noise. By heating the one closest to weathering The gas layer space makes it possible to use the element as a space covering Building construction to keep snow and elsfrel, whereby the arithmetically to be applied Significantly reduce loads.

Tensioning works are therefore used in the relief of the two-dimensional structural sections with large dimensions in both axes support free.

Depending on the main structures to be selected, these can be concave or convex overall shape in any geometric formations are used.
