Abstract

A method for manufacturing a compound construction element, in an extrusion process wherein a composite material is pressed through an extrusion die, which composite material includes a matrix of thermoplastic synthetic material including wood particles or other, cellulose containing particles in a content on the order of 50% by weight or more, wherein also one or more elongated additional elements are passed through the extrusion die, which additional elements are brought into tight engagement with the composite material, after which the compound element is shaped and preferably cooled in a die.

Claims

exact text as granted — not AI-modified
1 - 29 . (canceled)  
   
   
       30 . An elongated construction element comprising a composite material of a thermoplastic synthetic material and a mass of wood particles or other cellulose containing particles, as well as embedded longitudinal reinforcement elements.  
   
   
       31 . The elongated construction element according to  claim 30 , wherein said mass is present in an amount of at least 50% by weight.  
   
   
       32 . The elongated construction element according to  claim 30 , wherein said mass is present in an amount of at least 50-80% by weight.  
   
   
       33 . The elongated construction element according to  claim 30 , wherein said mass is present in an amount of at least 70-80% by weight.  
   
   
       34 . The elongated construction element according to  claim 30 , wherein the element has an E-modulus of more than approximately 6000 Mpa.  
   
   
       35 . The elongated construction element according to  claim 30 , wherein the element has an E-modulus of approximately 6000-12000 Mpa.  
   
   
       36 . The elongated construction element according to  claim 30 , wherein the element has an E-modulus of approximately 6000-9000 Mpa.  
   
   
       37 . The elongated construction element according to  claim 30 , made of nailable or screwable material.  
   
   
       38 . The elongated construction element according to  claim 34 , made of nailable or screwable material.  
   
   
       39 . The elongated construction element according to  claim 30 , designed as a tubular profile.  
   
   
       40 . The elongated construction element according to  claim 30 , designed as a multiple tubular profile.  
   
   
       41 . (canceled)  
   
   
       42 . (canceled)
