Apertured wall element

Abstract

A stay in place concrete formwork wall element comprises a major surface defining a portion of a face of the concrete wall, said surface having a plurality of uniformly sized and spaced apertures substantially throughout the surface allows concrete to seep partially through the apertures thereby providing an irregular trowelable surface facilitating the application of stucco or other wall coverings.

What is claimed is:  
     
         1 . [cancelled] A stay-in-place formwork element for use in formwork for pouring a concrete wall, said element having a surface defining a part of one face of said wall, said surface having a plurality of uniformly sized and spaced apertures substantially throughout said surface.  
     
     
         2 . [cancelled] An element as in  claim 1  wherein said element is made of polyvinyl chloride.  
     
     
         3 . [cancelled] An element as in  claim 1  or  2  wherein said apertures are between one thirty-second and one quarter of an inch in diameter and are spaced from one another between one thirty-second and three sixteenths of an inch.  
     
     
         4 . [cancelled] An element as in  claim 3  wherein said apertures are one eight of an inch in diameter and are spaced one sixteenth of an inch from one another.  
     
     
         5 . [cancelled] A stay in place formwork assembly for pouring a concrete wall, said assembly comprising a plurality of interconnected wall elements and a plurality of connecting members maintaining opposing faces of said formwork in spaced relationship, each of said wall elements comprising at least one surface defining a part of a face of the wall and having a plurality of uniformly sized and spaced apertures substantially throughout said surface.  
     
     
         6 . [cancelled] An assembly as in  claim 5  wherein said wall elements are made of polyvinyl chloride.  
     
     
         7 . [cancelled] An element as in  claim 5  or  6  wherein said apertures are between one thirty-second and on quarter of an inch in diameter and are spaced from one another between one thirty-second and three sixteenths of an inch.  
     
     
         8 . [cancelled] A stay in place formwork and concrete wall assembly comprising a plurality of interconnected wall elements, each of said wall elements comprising at least one surface defining a part of a face of the wall, a plurality of connecting members maintaining opposing faces of said formwork in spaced relationship, a plurality of apertures substantially throughout said surfaces of said wall elements, concrete poured within said formwork, said concrete extending through said apertures to form a thin layer of concrete on the outside of said wall element.  
     
     
         9 . [cancelled] A stay in place formwork and concrete wall assembly comprising a plurality of interconnected wall elements, each of said wall elements comprising at least one surface defining a part of a face of the wall, a plurality of connecting members maintaining opposing faces of said formwork in spaced relationship, a plurality of apertures substantially throughout said surfaces of said wall elements, concrete poured within said formwork, said concrete extending through said apertures to form a plurality of beads of concrete on the outside of said wall element.  
     
     
         10 . [cancelled] An assembly as in  claim 8  or  9  wherein said apertures are approximately one eighth inch in diameter and are spaced from adjacent apertures by approximately one sixteenth of an inch.  
     
     
         11 . [cancelled] A method of applying stucco to a concrete wall comprising the steps of: 
 erecting stay in place formwork comprising wall elements having a plurality of apertures substantially throughout a major surface of said wall elements;    pouring concrete into said formwork;    trowelling a layer of concrete that seeps through said apertures to produce an irregular surface; and, applying stucco to said trowelled layer of concrete.    
     
     
         12 . A stay-in-place formwork element for use in formwork for pouring a concrete wall, said element having: 
 a surface defining a part of one face of said wall; and,    said surface having a plurality of apertures substantially therethrough, such that when concrete is poured into the formwork, the concrete seeps through the apertures to form a plurality of heads or a thin layer of concrete on the outside of said formwork element.
