Abstract

A paving stone or paving slab, comprising a base, which is provided with a load-joint locking and displacement prevention means and has a multiplicity of base side faces and a head, which is arranged on the base and has a head upper side and a multiplicity of head side faces, the head on its head upper side having a smaller periphery in horizontal section than a nominal-dimension-based periphery of the base and the head side faces being designed such that, in the laid state of the paving stone or the paving slab, they form, together with a head side face of an adjacent identical or similar paving stone or identical or similar paving slab, a surface joint with a surface-joint width which is the same as or larger than a load-joint width of a load joint between bases of adjacent identical or similar paving stones or identical or similar paving slabs, the joint axes of the load joint and of the surface joint lying one on top of the other in the polysurface and the load joint and the surface joint being connected to one another, and a paved surface or block paving composed thereof.

         2 . The paving stone or paving slab of  claim 1  wherein said base side faces extend vertically or obliquely inward. 
     
     
         3 . The paving stone or paving slab of  claim 1  wherein said base is quadrilateral in said horizontal section. 
     
     
         4 . The paving stone or paving slab of  claim 1 , further comprising said load-joint locking and displacement prevention means has at least one spacer cam on at least one of said base side faces for locking said load joints. 
     
     
         5 . The paving stone or paving slab of  claim 1 , further comprising said load-joint locking and displacement prevention means has at least two parallel, vertical, outwardly protruding, interlock portions on at least one of said base side faces for preventing displacement, which in said laid state of the paving stone or the paving slab interact with said interlock portions on a base side face of an adjacent identical or similar paving stone or an adjacent identical or similar paving slab. 
     
     
         6 . The paving stone or paving slab of  claim 1 , further comprising said load-joint locking and displacement prevention means has a load-joint locking device separate from a displacement prevention device. 
     
     
         7 . The paving stone or paving slab of  claim 1 , further comprising said head is polygonal in said horizontal section. 
     
     
         8 . The paving stone or paving slab of  claim 1 , further comprising said head side faces and said base side faces extend in side-parallel fashion. 
     
     
         9 . The paving stone or paving slab of  claim 1 , further comprising said head side faces extend downward with their cross sections widening. 
     
     
         10 . The paving stone or paving slab of  claim 1 , further comprising a console which runs horizontally around a periphery, subdivides the paving stone or paving slab into said head and said base such that, in combination with an associated head side face in said laid state of the paving stone or the paving slab, it, together with a head side face of an adjacent identical or similar paving stone or an identical or similar paving slab, forms said surface joint. 
     
     
         11 . The paving stone or paving slab of  claim 10  wherein said head side faces merge into said console or said head side faces extends from a head upper side edge. 
     
     
         12 . The paving stone or paving slab of  claim 10  wherein said console extends horizontally or has a tray-like shape. 
     
     
         13 . The paving stone or paving slab of  claim 1 , further comprising at least one joint-material stabilizing device on at least one of said head side faces. 
     
     
         14 . The paving stone or paving slab of  claim 1 , further comprising said at least one dummy joint or at least one dummy joint with at least one joint-material stabilizing device. 
     
     
         15 . The paving stone or paving slab of  claim 1 , wherein said base is made of concrete. 
     
     
         16 . The paving stone or paving slab of  claim 1 , further comprising said head is made of a different material than said base. 
     
     
         17 . A paved surface composed of multiple paving stones or block paving composed of multiple paving slabs comprising:
 each said paving stone or paving slab comprising:
 a base comprising a load-joint locking and displacement prevention means and a multiplicity of base side faces; 
 a head arranged on said base having a head upper side and a multiplicity of head side faces; 
 said head on its head upper side having a smaller periphery in a horizontal section than a nominal-dimension-based periphery of said base; 
 said head side faces in a laid state of the paving stone or the paving slab form, together with a head side face of an adjacent identical or similar paving stone or identical or similar paving slab, a surface joint with a surface-joint width which is the same as or larger than a load-joint width of a load joint between bases of adjacent identical or similar paving stones or identical or similar paving slabs; and 
 joint axes of said load joint and of said surface joint lying one on top of the other in a polysurface and said load joint and said surface joint connected to one another; 
   joint material in said surface joints.   
     
     
         18 . The paved surface or block paving of  claim 17  wherein said paving stones or paving slabs are configured and arranged such that straight profiles of said surface joints with identical surface-joint widths are produced or upper sides of said paving stones or paving slabs are flat or configured or arranged such that profiles of said surface joints with irregular surface-joint widths are produced. 
     
     
         19 . The paved surface or block paving of  claim 1  wherein said base has a greater height than said head. 
     
     
         20 . The paving stone or paving slab of  claim 1 , further comprising said head is fastened by adhesive bonding to said base. 
     
     
         21 . The paving stone or paving slab of  claim 1 , further comprising said head is made of one of natural stone, ceramic, glass, brick, wood, plastic, or metal.
