Sandwich panel

Abstract

The present invention relates to a sandwich panel comprising a first covering layer, a second covering layer substantially parallel to the first covering layer, a sandwich core provided between the covering layers, and two opposite end surfaces on the longitudinal sides. The invention is characterized in that the end sides are of bevelled or stepped design in such a manner that (i) two sandwich panels which are joined to each other on the end sides in the same orientation and lie one against the other are arranged at 90° to each other, and (ii) two sandwich panels which are joined together on the end sides in an opposite orientation and lie one against the other lie in the same plane, i.e. a 180° connection is realized.

         12 . A sandwich panel, comprising:
 a first covering layer;   a second covering layer in substantial parallel relationship to the first covering layer; and   a sandwich core provided between the first and second covering layers;   said sandwich panel having two opposite longitudinal sides disposed parallel to one another to define end sides, respectively, said end sides having a beveled or stepped configuration to enable adjacent end sides of two of said sandwich panel to be joined in two ways, a first way in which the two sandwich panels are positioned in a 90° rotated relationship and joined to one another in a form-fitting manner such that the adjacent end sides of the sandwich panels come in contact with one another to thereby form a 90° corner, a second way in which one of the sandwich panels is rotated about 180° in relation to the other non-rotated sandwich panel and the two sandwich panels are joined to one another in a form-fitting manner such that the adjacent end sides of the sandwich panels come in contact with one another to realize a 180° connection.   
     
     
         13 . The sandwich panel of  claim 12  constructed for use in a prefabricated house. 
     
     
         14 . The sandwich panel of  claim 12 , wherein the end sides are stepped singly or multiply. 
     
     
         15 . The sandwich panel of  claim 12 , wherein the end sides are stepped singly to define a stepping having surfaces which all have a same width. 
     
     
         16 . The sandwich panel of  claim 12 , defined by a central line and constructed mirror-symmetrically with respect to the central line. 
     
     
         17 . The sandwich panel of  claim 12 , further comprising at least one sealing device provided on a surface of the end sides. 
     
     
         18 . The sandwich panel of  claim 17 , wherein the sealing device is embodied as a sealing bead. 
     
     
         19 . The sandwich panel of  claim 17 , wherein the surface of the end sides has a groove or recess to at least partially receive the sealing device. 
     
     
         20 . The sandwich panel of  claim 12 , wherein at least one of the first and second covering layers is made of a material selected from the group consisting of steel, aluminium, plastic, plastic compound and wood material. 
     
     
         21 . The sandwich panel of  claim 12 , wherein the sandwich core comprises a material selected from the group consisting of polyurethane, polystyrene and another insulating material. 
     
     
         22 . The sandwich panel of  claim 22 , wherein the other insulating material is mineral wool. 
     
     
         23 . The sandwich panel of  claim 12 , wherein the end sides are formed by a deformation of at least one of the first and second covering layers. 
     
     
         24 . The sandwich panel of  claim 12 , wherein the first and second covering layers are directly connected to one another or through interposition of a separate element.
