Prefabricated Concrete Element Having Textile Reinforcement and Retainers

Abstract

A prefabricated concrete element ( 10 ) having a textile reinforcement ( 17 ) comprising fastening elements ( 12, 13, 14, 15 ), which are connected directly to the reinforcement ( 17 ). The fastening elements ( 12 to 15 ) can have a bent form and pass through a flat side of the prefabricated concrete element ( 10 ). The fastening elements can also have a straight or elongated form and emerge on narrow sides of a plate-shaped prefabricated concrete element (I 0 ). Because of the direct connection between the fastening element ( 12 to 15 ) and the reinforcement ( 17 ), the prefabricated concrete element can have an especially extensive and thin form and thus can be used as a façade panel.

What is claimed is: 
     
         1 . A prefabricated concrete element comprising:
 a base body of a concrete having front and rear faces and a narrow side edge extending therebetween;   at least one layer of a textile reinforcement embedded in the base body; and   at least one fastening element that is directly connected to the textile reinforcement and includes a portion accessible from outside of the base body at one of the front and rear faces to provide a fastening point for the concrete element at the one of the front and rear faces;   wherein the direct connection between the fastening element and the textile reinforcement comprises a material-bonded connection.   
     
     
         2 . The prefabricated concrete element of  claim 1 , where the at least one fastening element is of a textile material. 
     
     
         3 . The prefabricated concrete element of  claim 1 , wherein the at least one fastening element is of a non-textile material. 
     
     
         4 . The prefabricated concrete element of  claim 1 , wherein the textile reinforcement has a generally planar configuration, and the at least one fastening element extends perpendicularly to the textile reinforcement. 
     
     
         5 . The prefabricated concrete element of  claim 1 , wherein the at least one layer of textile reinforcement includes a plurality of textile strands arranged to form a generally planar mesh. 
     
     
         6 . The prefabricated concrete element of  claim 1 , wherein the textile reinforcement comprises at least one of natural fibers, mineral fibers, glass fibers, carbon fibers, or metal fibers. 
     
     
         7 . The prefabricated concrete element of  claim 1 , wherein the fastening element comprises a planar anchoring section connected to the textile reinforcement and a connecting section extending away from said anchoring section out of the base body. 
     
     
         8 . The prefabricated concrete element of  claim 7 , wherein the anchoring section of the fastening element is configured as a flat plate. 
     
     
         9 . The prefabricated concrete element of  claim 7 , wherein the anchoring section of the fastening element is arranged so as to reach in a planar manner behind the textile reinforcement. 
     
     
         10 . The prefabricated concrete element of  claim 7 , wherein the anchoring section of the fastening element is inserted in a pocket of the textile reinforcement. 
     
     
         11 . The prefabricated concrete element of  claim 1 , wherein the textile reinforcement comprises two reinforcement layers. 
     
     
         12 . The prefabricated concrete element of  claim 1 , wherein the textile reinforcement comprises a mesh, and the fastening element has a head as an anchoring section, said head being arranged in the mesh. 
     
     
         13 . The prefabricated concrete element of  claim 12 , wherein the head has a groove on an outside circumference thereof for accommodation of parts of the textile reinforcement. 
     
     
         14 . A method for manufacturing a prefabricated concrete element, the method comprising:
 receiving by a shell form a unit formed of a textile reinforcement layer having fastening elements affixed to the textile reinforcement;   receiving uncured concrete into the shell form;   curing the concrete; and   removing from the shell form a prefabricated concrete element comprising a base body of the concrete having front and rear faces and a narrow side edge extending therebetween, the textile reinforcement layer embedded in the base body, and the fastening elements directly connected to the textile reinforcement and including a portion accessible from outside of the base body at one of the front and rear faces to provide a fastening point for the concrete element;   wherein the direct connection between the fastening elements and the textile reinforcement is a material-bonded connection.   
     
     
         15 . The method of  claim 14 , wherein the textile reinforcement layer includes a plurality of textile strands arranged to form a generally planar mesh. 
     
     
         16 . The method of  claim 14 , wherein the fastening elements are of a textile material. 
     
     
         17 . The method of  claim 14 , wherein the fastening elements are of a non-textile material.
