Architectural feature elements or decorative elements of metal

Abstract

Architectural feature elements or decorative elements of metal for supplementing and/or as a replacement for concrete elements, such as paving stones, curbstones, bollards, stelae, palisades or for elements of marble, polymer-concrete composite material or the like, such as slabs, tiles, beadwork, moldings or the like, which are manufactured from metal sheets as hollow bodies.

1 . Architectural feature elements or decorative elements of metal: for supplementing and/or as a replacement for concrete elements, such as paving stones, curbstones, bollards, stelae, palisades or for elements of marble, polymer-concrete composite material or the like, such as slabs, tiles, beadwork, moldings or the like, wherein they are manufactured from metal sheets as hollow bodies.  
   
   
       2 . The architectural feature elements or decorative elements as claimed in  claim 1 , wherein the hollow bodies are manufactured from metal sheets comprising steel, stainless steel, aluminum or other metals.  
   
   
       3 . The architectural feature elements or decorative elements as claimed in  claim 1 , wherein the outer surfaces of the hollow bodies are not machined.  
   
   
       4 . The architectural feature elements or decorative elements as claimed in  claim 1 , wherein the outer surfaces of the hollow bodies are machined by brushing, polishing, sandblasting, dyeing, stove-enameling or the like.  
   
   
       5 . The architectural feature elements or decorative elements as claimed in  claim 1 , wherein the upper sides of the hollow bodies can have a relief.  
   
   
       6 . The architectural feature elements or decorative elements as claimed in  claim 1 , wherein the hollow bodies are open on one side—preferably the lower side.  
   
   
       7 . The architectural feature elements or decorative elements as claimed in  claim 1 , wherein the hollow bodies are manufactured in each case from a single piece, with the outer skin at least approximately having a uniform thickness (d).  
   
   
       8 . The architectural feature elements or decorative elements as claimed in  claim 6 , wherein flanges projecting outward are arranged at the sides of the open lower sides.  
   
   
       9 . The architectural feature elements or decorative elements as claimed in  claim 8 , wherein the flanges project downward over the lower edges of the hollow body at least approximately by the wall thickness (d) of the hollow body and, as seen in top view, are arranged in each case in the clockwise direction at the beginning of a side, with the flanges being smaller than half of a side.  
   
   
       10 . The architectural feature elements or decorative elements as claimed in  claim 1 , wherein the hollow bodies are fitted in generic units or are fitted together with concrete elements or the like according to the preamble of  claim 1  by mixing or the inlay of a pattern or ornament.  
   
   
       11 . The architectural feature elements or decorative elements as claimed in  claim 1 , wherein the hollow bodies are inserted into a bed of sand, chippings, mortar, a bed with a concrete sub-base, of installation foam or of permanently elastic cement or the like.  
   
   
       12 . The architectural feature elements or decorative elements as claimed in  claim 1 , wherein the hollow bodies are provided with light elements, such as reflectors, lamps, floodlights or the like, or with heating elements for heating the upper side of the hollow bodies.  
   
   
       13 . The architectural feature elements or decorative elements as claimed in  claim 1 , wherein the hollow bodies have outflow openings for conducting surface waters away into the underlying surface or into a drainage system.  
   
   
       14 . The architectural feature elements or decorative elements as claimed in  claim 1 , wherein the hollow bodies are filled with foam or are filled with an insulating or sound-absorbing material or the like.  
   
   
       15 . The architectural feature elements or decorative elements as claimed in  claim 1 , wherein the hollow bodies are filled with concrete.  
   
   
       16 . The architectural feature elements or decorative elements as claimed in  claim 14 , wherein impressions are formed on one or more side walls of the hollow bodies, which impressions project inward and form a securing means for the filling or for the filling concrete.  
   
   
       17 . A method for filling the hollow bodies with concrete as claimed in  claim 15 , wherein a filling frame of plastic with recesses for the insertion of hollow bodies with the open lower side upward stands with height-adjustable, elastic supports on a base plate, the base plate, which is mounted on a vibrating table, having recesses which are assigned to the recesses of the filling frame, and the hollow bodies latching slightly into the recesses of the base plate, and the hollow bodies being filled from above with concrete and the concrete level with the upper side of the filling frame at the same time being smoothed and screeded level with the top lower edges of the hollow bodies.  
   
   
       18 . A method for manufacturing architectural feature elements or decorative elements as claimed in  claim 1 , wherein the manufacturing takes place by mechanical or hydro-mechanical deep-drawing of the metal sheets.  
   
   
       19 . An architectural feature elements and decorative elements of metal for one or more of supplementing and as a replacement for concrete elements, such as paving stones, curbstones, bollards, stelae, palisades and for elements of marble, polymer-concrete composite material or the like, such as slabs, tiles, beadwork, moldings or the like, wherein the feature elements and the decorative elements are manufactured from metal sheets as hollow bodies.  
   
   
       20 . A method for filling architectural feature elements and decorative elements of metal, with concrete, for one or more of supplementing and as a replacement for concrete elements, such as paving stones, curbstones, bollards, stelae, palisades and for elements of marble, polymer-concrete composite material or the like, such as slabs, tiles, beadwork, moldings or the like, the feature elements and the decorative elements are manufactured from metal sheets as hollow bodies and the hollow bodies are filled with concrete, wherein a filling frame of plastic with recesses for the insertion of hollow bodies with the open lower side upward stands with height-adjustable, elastic supports on a base plate, the base plate, which is mounted on a vibrating table, having recesses which are assigned to the recesses of the filling frame, and the hollow bodies latching slightly into the recesses of the base plate, and the hollow bodies being filled from above with concrete and the concrete level with the upper side of the filling frame at the same time being smoothed and screeded level with the top lower edges of the hollow bodies.
