Wall Element

Abstract

The invention relates to a wall element embodied in the form of a hollow precast concrete part comprising an internal wall, an external wall and a number of vertical channels which pass through the entire wall element from the top to lower faces thereof and whose cross-section reduces toward the wall base. When the wall element is positioned on the basement, it is possible to pour a cast-in-place concrete from the top into one or several vertical channels. The poured cast-in-place concrete attains through the channels, the wall base and further down in such a way that it penetrates into the basement or connecting elements. The hardened or solidified filling concrete forms a wedge which fixedly connects the wall element to a hollow brick of the basement.

1 . A wall element, comprising:
 a hollow concrete precast part having a top and a bottom, and including, An inside wall, an outside wall, a wall base, and a number of vertical channels extending from the top to the bottom through the hollow concrete precast part, each channel having a cross section that is tapered toward the wall base.   
   
   
       2 . The wall element according to  claim 1 , wherein the cross section for the channels is tapered in a downward direction. 
   
   
       3 . The wall element according to  claim 1 , wherein the channels have a rectangular cross section. 
   
   
       4 . The wall element according to  claim 3 , wherein a plurality of the channels are arranged parallel and side-by-side, and the hollow concrete precast part further includes narrow webs that extend respectively between two adjacent channels, between the inside wall and the outside wall. 
   
   
       5 . The wall element according to  claim 1 , wherein the channels are bounded by inside walls that are smooth. 
   
   
       6 . The wall element according to  claim 5 , wherein at least in a region of the wall base the inside walls of the channels form an acute angle relative to the wall base. 
   
   
       7 . The wall element according to  claim 1 , wherein the channels have an upper end with an opening for filling in a concrete mixed on site and a lower end with a through opening to a foundation for the wall element. 
   
   
       8 . The wall element according to  claim 1 , wherein the outside wall has a lower edge region that comprises control openings to permit a view of the channel located behind the control openings. 
   
   
       9 . The wall element according to  claim 1 , wherein the hollow concrete precast part comprises a poured, one-piece concrete element. 
   
   
       10 . The wall element according to  claim 9 , wherein the hollow concrete precast part is produced of self-compacting concrete (SCC). 
   
   
       11 . A component kit for interconnecting structural members, used for erecting the ground floor of a building and comprising:
 a number of ashlar hollow blocks each having hollow spaces and a top with openings, the blocks being arranged side-by-side to form a foundation;   wall elements as defined in  claim 1 , for which the vertical channels are aligned with the hollow spaces of the blocks; and   a free-flowing fill concrete that hardens inside the channels to form a wedge.   
   
   
       12 . The wall element according to  claim 6 , wherein the acute angle is between about 80° and about 85°.
