Method for Building Houses

Abstract

In a method for making a house, a foundation plate ( 1 ) consisting of a lightweight concrete is cast directly; on a drained and leveled substratum such that it extends a distance (a) outside the external walls of the house. Grooves ( 2 ) are milled in the foundation plate ( 1 ) where prefabricated wall elements ( 5 - 8 ) later are to be erected, where the bottom of the grooves is exactly horizontal and at the correct level. Next, prefabricated wall elements ( 58 ) are placed into the respective grooves ( 2 ) and glued to each other and to the foundation in the grooves. The wall elements have a height which is about 45 cm larger than the inner roof height of the house in order to facilitate the casting of a sub-floor of lightweight concrete inside the house once pipes and conduits for sanitary and electrical installations have been laid, and after parts of the walls ( 5 - 8 ) which have been cut out to provide openings ( 3, 4 ) for doors and windows, have been placed on the foundation plate ( 1 ). Any floor heating or floor finishing is placed on the sub-floor. The house is provided with a roof ( 10, 11 ) which comprises roof elements, which also are made from lightweight concrete and are provided with tensile reinforcement. The lightweight concrete used may comprise EPS spheres, cements, additives providing adhesion between the EPS spheres and the cement, and the water. Through this method the cost of erecting the structure for the house may be reduced by 30-50% as compared to traditionally made houses.

1 - 10 . (canceled) 
   
   
       11 . A method for making a structure for a house wherein at least the external walls of the house are made from prefabricated wall elements which are raised on a foundation and are attached to each other, whereupon the house is provided with a roof, and openings for doors and windows are cut out of the wall elements for installation of the doors and windows, wherein the foundation is cast from a lightweight concrete such that the foundation covers the entire base of the house and furthermore extends a given distance outside the outer walls of the house, the foundation being cast up to a predetermined distance below the level of the finished floor, wherein accurate grooves for the wall elements are formed in the foundation, said grooves having a width adapted to the thickness of the respective wall elements and having a bottom lying at a level at a predetermined distance below the level of the finished floor, wherein the wall elements, which also are cast from lightweight concrete, are placed into their respective grooves and are connected to each other and the foundation, wherein pipes and conduits for sanitary and electrical installations are mounted on the foundation, and wherein a sub-floor in lightweight concrete is cast on the foundation up to a predetermined, lower distance below the finished floor. 
   
   
       12 . A method according to  claim 11 , wherein the wall elements and the sub-floor are cast of the same or similar type of lightweight concrete as the foundation. 
   
   
       13 . A method according to  claim 11 , wherein the lightweight concrete used comprises EPS spheres, cement, additives which provide adhesion between the EPS spheres and the cement, and water. 
   
   
       14 . A method according to  claim 11 , wherein the parts of the wall elements which are cut out for doors and windows are cast into the sub-floor. 
   
   
       15 . A method according to  claim 11 , wherein the foundation extends a distance in the order of magnitude 1 m outside the external walls of the house. 
   
   
       16 . A method according to  claim 11 , wherein said predetermined distance to which the foundation is cast below the level of the finished floor, is about 45 cm. 
   
   
       17 . A method according to  claim 11 , wherein the order of magnitude of the thickness of the wall elements is 25 cm. 
   
   
       18 . A method according to  claim 11 , wherein slots for downpipes from the roof are milled into some of the corners of the house. 
   
   
       19 . A method according to  claim 11 , wherein the wall elements are provided at least externally with a layer of plaster. 
   
   
       20 . A method according to  claim 11 , wherein the roof of the house comprises elements which are made from a similar or the same lightweight concrete as the wall elements and are provided with tensile reinforcement. 
   
   
       21 . A house made by the method according to  claim 11 . 
   
   
       22 . A method according to  claim 12 , wherein the lightweight concrete used comprises EPS spheres, cement, additives which provide adhesion between the EPS spheres and the cement, and water. 
   
   
       23 . A method according to  claim 12 , wherein the parts of the wall elements which are cut out for doors and windows are cast into the sub-floor. 
   
   
       24 . A method according to  claim 12 , wherein the foundation extends a distance in the order of magnitude 1 m outside the external walls of the house. 
   
   
       25 . A method according to  claim 12 , wherein said predetermined distance to which the foundation is cast below the level of the finished floor, is about 45 cm. 
   
   
       26 . A method according to  claim 12 , wherein the order of magnitude of the thickness of the wall elements is 25 cm. 
   
   
       27 . A method according to  claim 12 , wherein slots for downpipes from the roof are milled into some of the corners of the house. 
   
   
       28 . A method according to  claim 12 , wherein the wall elements are provided at least externally with a layer of plaster. 
   
   
       29 . A method according to  claim 12 , wherein the roof of the house comprises elements which are made from a similar or the same lightweight concrete as the wall elements and are provided with tensile reinforcement.
