Pneumatic floor or wall structure

Abstract

The invention relates to an inflatable floor or wall structure for mobile buildings, which is formed by flexible boundary layers that are impermeable to air. A plurality of air chambers are formed between the boundary layers. According to the invention, one side of the pneumatic floor structure or wall structure is provided with a plurality of stiff profiled surface elements. The surface elements are mutually spaced such that the floor or wall structure can be rolled up after being deflated.

1 . A pneumatic bounding structure for mobile buildings, comprising: 
 flexible boundary layers which are impermeable to air; and    a plurality of air chambers formed between the boundary layers, wherein    one side of the pneumatic structure has a plurality of stiff profiled surface elements applied thereon; and    the surface elements are mutually spaced apart such that the floor structure can be rolled up after being relieved from pressure.    
   
   
       2 . The pneumatic floor structure or wall structure according to  claim 1 , where 
 adjacent structures are connected by mutually overlapping boundary layers; and    the pressurization in one of the adjacent structures generates a form-locking and force-locking connection between the boundary layers.    
   
   
       3 . The pneumatic structure according to  claim 1 , wherein 
 a coupling profile is arranged between adjacent structures;    the coupling profile interlocks air chambers of the adjacent structures upon with the admission of pressure.    
   
   
       4 . The pneumatic structure according to  claim 1 , wherein 
 heat insulation is provided by radiation-reflecting intermediate layers, which are arranged in the air chambers in a non-contact manner, and are essentially parallel to the boundary layers.    
   
   
       5 . The pneumatic structure according to  claim 4 , wherein 
 the air chambers are arranged in a plurality of layers; and    mutual separation between the intermediate layers can be changed by admission of pressure to individual air chambers, to adjust heat transmission of the structure in a targeted manner.    
   
   
       6 . The pneumatic structure according to  claim 1 , wherein 
 a reduction of pressure in individual air chambers relative to ambient atmospheric pressure causes arching of the boundary layers according to their stiffness, whereby thickness of the air layer is reduced and the heat transmission is increased.    
   
   
       7 . The pneumatic floor structure according to  claim 1 , further comprising electric heating foils mounted on an interior side of a boundary layer.  
   
   
       8 . The pneumatic structure according to  claim 1 , wherein: 
 heated or cooled compressed air flows through individual air chambers for the purpose of air-conditioning a space; and    another air chamber, through which no flow takes place, is provided for heat insulation between the air chambers through which the flow takes place, and a boundary layer.    
   
   
       9 . The pneumatic structure according to  claim 1 , wherein: 
 air chambers are arranged in a plurality of layers; and    the admission of pressure to the air chambers establishes a level compensation in the case of an uneven base.
