Building system, beam element, column and method

Abstract

The present invention provides a building system, including at least partially hollow building elements, in which hollow spaces of the building elements connect to one another for the passage of lines. The hollow spaces are accessible and remain accessible via openings in the building elements for fitting or removing the lines. The building elements include a beam element, a column, a wall element and/or a floor element. A reinforcement arranged inside the building elements comprises parallel rods, to which supporting elements are attached by at least one a double weld.

1 . Building system, comprising building elements provided with hollow spaces, in which the hollow spaces of the building elements connect to one another for the passage of lines.  
   
   
       2 . Building system according to  claim 1 , in which the hollow spaces of the building elements are accessible and remain accessible via openings in the building elements for fitting or removing the lines.  
   
   
       3 . Building system according to  claim 1 , in which the building elements comprise a beam element and/or a column.  
   
   
       4 . Building system according to  claim 1 , in which the building elements comprise a wall element and/or a floor element.  
   
   
       5 . Building system according  claim 1 , in which the building elements comprise an internal reinforcement, which reinforcement comprises at least two rods arranged approximately parallel and connected to one another by a number of supporting elements, the supporting elements being attached to the rods by means of at least a double weld.  
   
   
       6 . Building system according to  claim 5 , in which the double weld comprises two weld spots which are arranged at opposite sides of an end of the supporting elements.  
   
   
       7 . Building system according to  claim 3 , the beam element comprising: 
 an elongate beam member;    a reinforcement provided in the beam member; and    a hollow space extending inside the beam-member for arranging lines therein.    
   
   
       8 . Building system according to  claim 7 , in which the reinforcement comprises: 
 at least two rods; and    supporting elements which are fitted to a rod by their first end and to another rod by their second end.    
   
   
       9 . Building system according to  claim 8 , in which the ends of the supporting elements are attached to the respective rod by means of at least one double weld.  
   
   
       10 . Building system according to  claim 7 , in which the beam element comprises a bottom part which is wider than a top part arranged parallel on the bottom part.  
   
   
       11 . Building system according to  claim 10 , in which the bottom part is a first slab, and in which the top part is a second slab which is arranged parallel to the bottom part and is separated from the first slab by the reinforcement and the hollow space.  
   
   
       12 . Building system according to  claim 3 , wherein the column comprises a support member provided with a hollow space, a reinforcement being arranged inside the support member.  
   
   
       13 . Building system according to  claim 12 , in which an opening is provided in a side wall of the support member, which opening extends from the hollow space to the outer side of the column in order to make the hollow space accessible.  
   
   
       14 . Building system according to  claim 12 , comprising a shoulder which is widened relative to the support member in order to arrange a building element thereon.  
   
   
       15 . Building system according to  claim 1 , wherein the hollow spaces provide an intermediate space greater than 15 cm.  
   
   
       16 . Building system according to  claim 15 , wherein the intermediate space is greater than about 1 m.  
   
   
       17 . Building system according to  claim 15 , wherein slabs of the building elements are relatively thin compared to the intermediate space.  
   
   
       18 . Building system according to  claim 1 , wherein the hollow spaces extend in both a length and a width direction of the building elements.  
   
   
       19 . Building system according to  claim 2 , wherein the openings extend over substantially the entire length of the building elements.  
   
   
       20 . Building system according to  claim 5 , wherein a diameter of the supporting elements of the reinforcement is greater than about 16 mm.  
   
   
       21 . Method comprising constructing a building from building elements provided with hollow spaces, in which the hollow spaces of the building elements connect to one another for the passage of lines.  
   
   
       22 . Method according to  claim 21 , comprising building elements provided with hollow spaces, in which the hollow spaces of the building elements connect to one another for the passage of lines.
