Insulating prefab wall structure

Abstract

The present invention describes a prefab wall structure which provides a reduced thermal conductivity. More particularly, the prefac wall structure comprises a stud assembly made of at least two studs secured one to the other through a contact surface lateral to said stud. This reduces the conductivity of the temperature exchange throughout the wall.

1 . A prefab wall structure comprising;
 a. two opposite first and second side wall boards;   b. a stud assembly comprising at least a first and second stud member between the two opposite side wall boards, the first stud member being secured with first side wall board, the second stud member being secured with the second side wall board, said first and second stud members being in contact one to the other to form a surface of contact, the surface of contact being non parallel to said first and second wall boards, thereby defining with said first and second wall boards and a plurality of stud assembly a plurality of cavities, wherein each cavity has a depth higher to a thickness of each of said stud member, and has a depth equivalent to the thickness of said stud assembly.   
   
   
       2 . The prefab wall structure of  claim 1 , wherein said stud members are perpendicularly secured with said wall boards in the sense of the thickness of said wall structure. 
   
   
       3 . The prefab wall structure of  claim 1 , wherein said cavity is filled up with an insulating material. 
   
   
       4 . The prefab wall structure of  claim 1 , wherein said studs member in said stud assembly are separated by an insulating membrane. 
   
   
       5 . The prefab wall structure of  claim 1 , wherein said studs member in said stud assembly are separated by an intermediate member. 
   
   
       6 . The prefab wall structure of  claim 1 , wherein said studs member are 2″×4″ stud members. 
   
   
       7 . A prefab wall structure comprising a stud assembly comprising at least a first and second stud member between the two opposite side wall boards, the first stud member being secured with first side wall board, the second stud member being secured with the second side wall board, said first and second stud members being in contact one to the other to form a surface of contact, the surface of contact being non parallel to said first and second wall boards, thereby defining with said first and second wall boards and a plurality of stud assembly a plurality of cavities, wherein each cavity has a depth higher to a thickness of each of said stud member, and has a depth equivalent to the thickness of said stud assembly. 
   
   
       8 . A method of manufacturing a prefab wall structure comprising the steps of:
 a. fixing a stud member on a wall board to form a first prewall structure;   b. assembling the first prewall structure to a second prevail struture by securing the stud member of a first prewall structure with the stud member of second prewall structure, the studs secured together forming a stud assembly, in manner to obtain a prefab wall structure, thereby defining with said wall boards of said first and second prewall structures and a plurality of stud assembly a plurality of cavities, wherein each cavity has a depth higher to a thickness of each of said stud member, and has a depth equivalent to the thickness of said stud assembly   
   
   
       9 . The method of  claim 8 , wherein said stud member is fixed longitudinally to said wall board.
