Abstract

The invention describes a load-bearing system which is composed of a plurality of components of different materials. At least one component that dissipates load here is composed of plastic. A frictional bond achieved via at least one bonding technique transmits the loads for the various components. The plastic can be transparent.

Claims

exact text as granted — not AI-modified
1 . A composite load-bearing system,
 wherein   plastics are joined with at least one further material to give a load-bearing system.   
   
   
       2 . The composite system according to  claim 1 ,
 wherein   the materials used have different moduli of elasticity.   
   
   
       3 . The composite system according to  claim 1 ,
 wherein   the modulus of elasticity of the plastics material is more than 150 N/mm 2 .   
   
   
       4 . The composite system according to  claim 1 ,
 wherein   the stiffer material is further from the centre-of-gravity axis.   
   
   
       5 . The composite system according to  claim 1 ,
 wherein   the softer material is a transparent plastic.   
   
   
       6 . The composite system according to  claim 1 ,
 wherein   the softer material is a translucent plastic.   
   
   
       7 . The composite system according to  claim 1 ,
 wherein   the softer material is a coloured plastic.   
   
   
       8 . The composite system according to  claim 1 ,
 wherein   the softer material is a light-emitting plastic.   
   
   
       9 . The composite system according to  claim 1 ,
 wherein   there are cavities in the softer material.   
   
   
       10 . The composite system according to  claim 1 ,
 wherein   the softer material can be a plastics laminate.   
   
   
       11 . The composite system according to  claim 1 ,
 wherein   the softer material can be a material composed of layers.   
   
   
       12 . The composite system according to  claim 1 ,
 wherein   the harder material is timber or a timber material.   
   
   
       13 . The composite system according to  claim 1 ,
 wherein   the harder material is a metallic material (iron, steel, aluminium) selected from the group consisting of iron, steel and aluminum.   
   
   
       14 . The composite system according to  claim 1 ,
 wherein   the harder material is glass.   
   
   
       15 . The composite system according to  claim 1 ,
 wherein   the harder material is concrete or a natural stone.   
   
   
       16 . The composite system according to  claim 1 ,
 wherein   the harder material is a filled or glass-fibre-reinforced plastic.   
   
   
       17 . The composite system according to  claim 1 ,
 wherein   the selected means of bonding comprise screws or bolts.   
   
   
       18 . The composite system according to  claim 1 ,
 wherein   the selected means of bonding comprise pegs or dowel pins.   
   
   
       19 . The composite system according to  claim 1 ,
 wherein   the selected means of bonding comprise studs.   
   
   
       20 . The composite system according to  claim 1 ,
 wherein   the selected means of bonding comprise rivets.   
   
   
       21 . The composite system according to  claim 1 ,
 wherein   the selected means of bonding comprise an adhesive.   
   
   
       22 . The composite system according to  claim 1 ,
 wherein   the bonding is based on friction.   
   
   
       23 . The composite system according to  claim 1 ,
 wherein   the bonding has been is produced with the aid of thermoforming.   
   
   
       24 . The composite system according to  claim 1 ,
 wherein two or more   means of bonding are used in combination.   
   
   
       25 . The composite system according to  claim 1 ,
 wherein   it is loaded as a transverse-load-bearing element, horizontally.   
   
   
       26 . The composite system according to  claim 1 ,
 wherein   it is loaded as a prop, vertically.   
   
   
       27 . The composite system according to  claim 1 ,
 wherein   the two materials are involved in the structure in the shape of an I.   
   
   
       28 . The composite system according to  claim 1 ,
 wherein   the materials are bonded to give a solid load-bearing element.   
   
   
       29 . The composite system according to  claim 1 ,
 wherein, when   viewed in cross section, it has the shape of a polygonal box.   
   
   
       30 . The composite system according to  claim 1 ,
 wherein, when   viewed in cross section, it has the shape of a folded-plate structure.   
   
   
       31 . The composite system according to  claim 1 ,
