Shaped pavestone

Abstract

A molded block is proposed, in particular one made of concrete, for a paving-stone covering, the block having side faces with rounded portions in the form of a clothoid. In order to provide a flexible type of laying, the block form is designed as a cube or a multiple thereof.

1 . Molded block, in particular one made of concrete, for a paving-stone covering, having substantially planar faces, at least one face having a rounded portion over a large area running toward at least one side edge, characterized in that the molded block has the shape of a single or multiple cube.  
     
     
         2 . Molded block according to    claim 1   , characterized in that the form of a cube with the edge length L is provided, it being preferably possible for each of the cube faces to be used as a horizontal upper face.  
     
     
         3 . Molded block according to    claim 1    or    2   , characterized in that at least one of the cube faces has a rounded portion over a large area, whose radius of curvature preferably changes constantly toward the corner region.  
     
     
         4 . Molded block according to one of the preceding claims, characterized in that the size of a twofold cube is provided, with a width and height of edge dimension L and a length of edge dimension 2L, provision being made to rotate the molded block through 90° and/or 180° about its horizontal longitudinal axis during laying, with a constant block height.  
     
     
         5 . Molded block according to one of the preceding claims, characterized in that a size of a fourfold cube is provided, the rotation of which takes place about a vertical axis of rotation.  
     
     
         6 . Molded block according to one of the preceding claims, characterized in that the radius of curvature of the rounded portions running toward the side edge is designed as a curve with, in plan view or side view, a radius of curvature which decreases constantly toward the corner regions (clothoid).  
     
     
         7 . Molded block according to one of the preceding claims, characterized in that the face of the molded block is designed to form a clothoid toward a side edge over approx. ¼ to ⅙ of the cube length L, the clothoidal curvature being variable with a radius of curvature tapering toward the corner region.  
     
     
         8 . Molded block according to one of the preceding claims, characterized in that at least one side edge between two side faces or between side faces and upper/lower face is designed to be sharp-edged or irregularly broken or rounded.  
     
     
         9 . Molded block according to one of the preceding claims, characterized in that the cube-shaped basic block and/or the double-square block and/or the fourfold square block has/have clothoidal rounded portions on at least two opposing or on three side faces, said rounded portions being arranged in the clockwise direction or running in opposite direction or opposed in plan view of the molded block.  
     
     
         10 . Molded block according to one of the preceding claims, characterized in that a small block with a reduced side edge and/or a wedge-shaped supplementary block are provided.
