Abstract
The invention relates to a composite paving structure consisting of elements forming a pattern. The structure is made up of laying units each of which has a group of elements adjoining at their respective peripheries and held together by predetermined rupture zones. Supplementing stones are disposed at the boundaries of adjacent units. The stones have one or more elements and extend, in each case, into recesses in both of two adjacent units. Preferably, the stones are of one shape and the pattern is a herringbone pattern. The units may be offset relative to one another in the herringbone pattern.
Claims41
A composite paving structure for traffic areas or other graded or inclined ground surfaces, comprising an assembly of juxtaposed laying units and linking stones, each said laying unit being a relatively large unitary slab transportable as a unit by being gripped mechanically at opposite lateral sides thereof, said slab having preformed therein elongate rupture zones subdividing it into adjoined stones and along which after being laid it is breakable under stress into laterally interengaged individual stones, each said laying unit having in at least one lateral side thereof at least one recess extending its full height and substantially corresponding in facial shape and size to one said individual stone or a fraction or multiple thereof, each said unit being laid with at least one lateral side thereof lying at and along, and having therein at least one said recess each of which confronts a said recess in, a lateral side of at least one other said unit, each set of said confronting recesses being filled by at least one said linking stone inserted thereinto and which interconnects the respective juxtaposed laying units by extending across the gap between them, each said linking stone having the same height as the laying unit and having substantially the facial shape and size of one said individual stone or of a fraction or multiple thereof.
A composite paving structure for traffic areas or other graded or inclined ground surfaces, comprising an assembly of juxtaposed laying units and concrete linking stones, each said laying unit being a relatively large unitary slab of concrete transportable as a unit by being gripped mechanically at opposite lateral sides thereof, said slab having preformed therein elongate rupture zones subdividing it into adjoined stones and along which after being laid it is breakable under stress into laterally interengaged individual stones, each said laying unit having in at least one lateral side thereof at least one recess extending its full height and substantially corresponding in facial shape and size to one said individual stone or a fraction or multiple thereof, each said unit being laid with at least one lateral side thereof lying at and along, and having therein at least one said recess each of which confronts a said recess in, a lateral side of at least one other said unit, each set of said confronting recesses being filled by at least one said linking stone inserted thereinto and which interconnects the respective juxtaposed laying units by extending across the gap between them, each said linking stone having the same height as said laying units, each of said individual stones as formed by said laying units breaking along said rupture zones, also each of said linking stones, having quadrilateral contour that is centrosymmetrical and covers an area approximately twice as long as it is wide, and having on and along its four sides lateral projections and withdrawn portions which form at opposite sides of the stone configurations that, by parallel translation of such sides, are identical, said individual stones together with said linking stones constituting a herringbone pattern of interengaged stones that extends without substantial interruption from each into the next of said juxtaposed laying units, with a shorter side of each stone lying adjacent to half of a longer side of another stone.
A laying unit for a composite paving structure, comprising a relatively large unitary paving slab that is transportable and layable as a unit upon a ground surface by being gripped mechanically at opposite lateral sides thereof, said slab having preformed therein a multiplicity of elongate rupture zones subdividing it into adjoined stones and along which after being laid it is breakable under stress into laterally interengaged individual stones, said slab having in at least one lateral side thereof at least one recess extending its full height and corresponding in facial shape and size to one of said individual stones or a whole number fraction thereof, said rupture zones being so disposed that said individual stones form a herringbone pattern wherein a shorter side of each such stone lies adjacent to part of a longer side of another such stone.
A laying unit for a composite paving structure, comprising a relatively large unitary paving slab that is transportable and layable as a unit upon a ground surface by being gripped mechanically at opposite lateral sides thereof, said slab having preformed therein a multiplicity of elongate rupture zones subdividing it into adjoined stones and along which after being laid it is breakable under stress into laterally interengaged individual stones, said slab having in at least one lateral side thereof at least one recess extending its full height and corresponding in facial shape and size to one of said individual stones or a whole number fraction thereof, said individual stones as formed by said slab breaking along said rupture zones having on and along adjacent sides thereof complementary, interengaged protuberances and recessed parts which respectively overlie one another and resist relative vertical displacement of said individual stones.
A laying unit for a composite paving structure, comprising a relatively large unitary paving slab that is transportable and layable as a unit upon a ground surface by being gripped mechanically at opposite lateral sides thereof, said slab having preformed therein a multiplicity of elongate rupture zones subdividing it into adjoined stones and along which after being laid it is breakable under stress into laterally interengaged individual stones, said slab having in at least one lateral side thereof at least one recess extending its full height and corresponding in facial shape and size to one of said individual stones or a whole number faction thereof, said rupture zones each being defined by a dummy gap formed in and continuously along the upper and/or lower side of said slab, said dummy gap being varied in height lengthwise thereof.
A laying unit for a composite paving structure, comprising a relatively large unitary paving slab that is transportable and layable as a unit upon a ground surface by being gripped mechanically at opposite lateral sides thereof, said slab having preformed therein a multiplicity of elongate rupture zones subdividing it into adjoined stones and along which after being laid it is breakable under stress into laterally interengaged individual stones, said slab having in at least one lateral side thereof at least one recess extending its full height and corresponding in facial shape and size to one of said individual stones or a whole number faction thereof, each said rupture zone being constituted by a series of rupture sections formed in said slab and separated one from another by dummy gaps extending through the entire height of said slab at locations between said rupture sections, said adjoined stones being each connected to at least another by a plurality of said rupture sections.
A laying unit for a composite paving structure, comprising a relatively large unitary paving slab that is transportable and layable as a unit upon a ground surface by being gripped mechanically at opposite lateral sides thereof, said slab having preformed therein a multiplicity of elongate rupture zones subdividing it into adjoined stones and along which after being laid it is breakable under stress into laterally interengaged individual stones, said slab having in at least one lateral side thereof at least one recess extending its full height and corresponding in facial shape and size to one of said individual stones or a whole number faction thereof, said slab having embedded therein at least one flexible tying insert extending from within at least one stone thereof into an adjacent stone thereof across the rupture zone therebetween.
A laying unit for a composite paving structure, comprising a relatively large slab that is transportable and layable as a unit upon a ground surface by being gripped mechanically at opposite lateral sides thereof, said slab having preformed therein a multiplicity of elongate rupture zones subdividing it into adjoined stones and along which after being laid it is breakable under stress into laterally interengaged individual stones, said rupture zones being so disposed that said individual stones form a herringbone pattern wherein a shorter side of each such stone lies adjacent to part of a longer side of another such stone.
A composite paving structure for traffic areas or other graded or inclined ground surfaces, comprising an assembly of juxtaposed laying units, each said laying unit being a relatively large slab of concrete that is transportable as a unit by being gripped mechanically at opposite lateral sides thereof, said slab having preformed therein elongate rupture zones subdividing it into adjoined stones and along which after being laid it is breakable under stress into laterally interengaged individual stones, each said laying unit being laid with at least one lateral side thereof lying at and along a lateral side of at least one other said laying unit, said rupture zones being so disposed in each said unit and said units being so juxtaposed that the individual stones formed by said units breaking along said rupture zones constitute a herringbone pattern of interengaged stones that extends from each into the next of said laying units with a shorter side of each stone lying adjacent to part of a longer side of another stone.
