Shuttering element for the construction of a hemispherical building and method of shuttering in construction thereof

Abstract

Shuttering elements ( 1, 20 ) for the construction of a hemispherical building are disclosed, comprising webs ( 10 ) along the side edges ( 4, 5 ) thereof. The webs ( 10 ) project from the underside ( 8 ) of the shuttering element ( 1, 20 ), facing what is to become the building interior ( 36 ). The individual shuttering elements ( 1, 20 ) may be connected using the webs ( 10 ), by means of quick-fasteners ( 12, 13 ) to produce the complete shuttering and are multiply re-usable. The invention further relates to a method for the construction of a hemispherical building.

1 . Shuttering element for constructing a hemispherical building, characterized in that the shuttering element ( 1 ,  20 ) has ribs ( 10 ) projecting toward the building interior ( 36 ) along the side edges ( 4 ,  5 ).  
     
     
         2 . Shuttering element according to  claim 1 , characterized in that at least two shuttering elements ( 1 ,  20 ) are interconnectable by snap-on fasteners ( 12 ,  13 ).  
     
     
         3 . Shuttering element according to  claim 1 , characterized in that the ribs ( 10 ) deviate from the vertical relative to the shuttering element ( 1 ), specifically at an angle (β) from 1-10°.  
     
     
         4 . Shuttering element according to one of claims  1  through  3 , characterized in that the shuttering element ( 1 ) has a tapered shape, specifically a wedge shape, from the base edge ( 3 ) to the top edge ( 2 ).  
     
     
         5 . Shuttering element according to one of claims  1  through  4 , characterized in that the shuttering element ( 1 ) corresponds to an 18° sector of the circle forming the ground surface of the hemispherical building.  
     
     
         6 . Shuttering element according to one of claims  1  through  5 , characterized in that the shuttering element ( 1 ) is composed of a material of low density, specifically glass-fiber-reinforced plastic or aluminum.  
     
     
         7 . Shuttering element according to  claim 6 , characterized in that the ribs ( 10 ) are composed of metal, specifically aluminum.  
     
     
         8 . Shuttering element according to one of the foregoing claims, characterized in that an insulation layer ( 30 ) may be attached, specifically, adhesively bonded, to the exterior ( 7 ) of the shuttering element ( 1 ).  
     
     
         9 . Method of shuttering for constructing a hemispherical building, wherein multiple shuttering elements ( 1 ,  20 ) are linked together and connected to form complete shuttering, concrete ( 32 ) is subsequently applied to the exterior ( 7 ) of the shuttering elements ( 1 ,  20 ), and after the concrete ( 32 ) has hardened the shuttering elements ( 1 ,  20 ) are removed from the building interior ( 36 ), characterized in that the shuttering elements ( 1 ,  20 ) are joined by ribs ( 10 ) using snap-on fasteners ( 12 ,  13 ).  
     
     
         10 . Method according to  claim 9 , characterized in that an insulation layer ( 30 ) is applied to the exterior ( 7 ) of the shuttering elements ( 1 ,  20 ), specifically bonded on, before concrete ( 32 ) is applied thereto.
