Wall formwork with sleeve for anchor holes, sleeve and cleaning method

Abstract

The invention relates to a wall formwork for the construction of walls with a formwork facing and elements which support the formwork facing, with several anchor holes which pass through supporting elements, with a sleeve made of plastic which is held in a force-fit and/or form-fit manner in an anchor hole, wherein the sleeve extends from one end of the anchor hole to the other end of the anchor hole, and wherein the outer face of the sleeve tightly abuts the inner face of the anchor hole at the side of the formwork facing, characterized in that each anchor hole comprises a sleeve. The invention further relates to a method for cleaning a wall formwork with the features according to one of the preceding claims, characterized in that concrete is driven out of an anchor hole.

1 . A wall formwork for the construction of walls with a formwork facing and elements which support the formwork facing, with several anchor holes which pass through supporting elements, with a sleeve made of plastic which is held in a force-fit and/or form-fit manner in an anchor hole, wherein the sleeve extends from one end of the anchor hole to the other end of the anchor hole, and wherein the outer face of the sleeve tightly abuts the inner face of the anchor hole at the side of the formwork facing, characterized in that each anchor hole comprises a sleeve. 
     
     
         2 . The wall formwork according to  claim 1 , characterized in that the sleeve comprises a flange which prevents the sleeve from being pulled outwards out of the wall formwork. 
     
     
         3 . The wall formwork according to  claim 2 , characterized in that the flange rests on a supporting element. 
     
     
         4 . The wall formwork according to  claim 2 , characterized in that the flange is flush with the formwork facing and/or with the anchor hole. 
     
     
         5 . The wall formwork according to  claim 4 , characterized in that the flange is located in an enlargement of the anchor hole or in a recess of the formwork facing. 
     
     
         6 . The wall formwork according to  claim 1 , characterized in that at least one sleeve ( 4 ) is closed by a cap ( 14 ) at the side of the formwork facing. 
     
     
         7 . The wall formwork according to  claim 1 , characterized in that the sleeve has grooves on its outer face. 
     
     
         8 . The wall formwork according to  claim 7 , characterized in that the grooves run parallel to the longitudinal axis of the sleeve. 
     
     
         9 . The wall formwork according to  claim 7 , characterized in that at one end of the sleeve there is a section which is free of grooves and which tightly abuts the inner face of the anchor hole. 
     
     
         10 . The wall formwork according to  claim 1 , characterized in that the sleeve comprises a flange on only one side. 
     
     
         11 . The wall formwork according to  claim 1 , characterized in that the sleeve comprises a seal of elastic material on the side of the formwork facing. 
     
     
         12 . The wall formwork according to  claim 11 , characterized in that the seal comprises a protruding bead and/or an inwardly projecting lip. 
     
     
         13 . The wall formwork according to  claim 1 , characterized in that the sleeve has an internal thread. 
     
     
         14 . The wall formwork according to  claim 1 , characterized in that the sleeve is held in the anchor hole in a form-fit manner by one or more latching elements. 
     
     
         15 . A sleeve for a wall formwork according to  claim 1 , with only one flange at one end and grooves on the outer face reaching the other end of the sleeve but not the flange, so that a section is free of grooves. 
     
     
         16 . A method for cleaning a wall formwork with the features according to  claim 1 , characterized in that concrete is knocked out of an anchor hole.
