Method for manufacturing a building block

Abstract

A method for manufacturing a building element with at least two reference surfaces that are spaced apart and have a predetermined position relative to each other. The method includes forming at least two part-elements, with each part-element being formed of a hardened molding mass such that a first of the part-elements defines a first of the reference surfaces and a second of the part-elements defines a second of the reference surfaces. The two part-elements are positioned against each other with a resiliently deformable tie layer therebetween so that the first and second references surfaces face away from each other and the predetermined position thereof is established, after which the tie layer is hardened.

1 . A method for manufacturing a building element with at least two reference surfaces that are spaced apart and have a predetermined position relative to each other, the method comprising the steps of: 
 forming at least two part-elements, each part-element being formed of a hardened molding mass such that a first of the part-elements defines a first of the reference surfaces and a second of the part-elements defines a second of the reference surfaces;    positioning the two part-elements against each other with a resiliently deformable tie layer therebetween so that the first and second references surfaces face away from each other and the predetermined position thereof is established; and then    hardening the tie layer.    
     
     
         2 - 6 . (canceled)  
     
     
         7 . A method according to  claim 1 , further comprising the step of placing a reinforcement in the tie layer, wherein the reinforcement defines a securing means extending from the building element after the hardening step.  
     
     
         8 . A method according to  claim 1 , wherein the part-elements have through-holes aligned as a resulting of the position step, the method further comprising inserting means in the through-holes for mechanically securing the part-elements to each other.  
     
     
         9 . A method according to  claim 1 , further comprising the step of coating at least one of the reference surfaces with a synthetic material or a metal foil.  
     
     
         10 . A method according to  claim 1 , further comprising the step of providing at least one of the reference surfaces with a non sticky resilient coating.  
     
     
         11 . A method according to  claim 1 , wherein each of the reference surfaces is flat.  
     
     
         12 . A method according to  claim 1 , wherein the reference surfaces are parallel to each other after the positioning step.  
     
     
         13 . A method according to  claim 1 , wherein the part-elements are formed of concrete, foamed glass, foamed aluminium or a composite material.  
     
     
         14 . A method according to  claim 1 , wherein the tie layer is formed of glue, cement, or a synthetic material.
