Wall formwork with optional anchor point

Abstract

The invention relates to a wall formwork ( 1 ) for concrete structures, comprising a basic body ( 18 ), an outer face configured as a formwork facing ( 6 ), and anchor points in the form of anchor holes ( 2, 3, 4, 5 ) for the detachable connection to other wall formworks. It is proposed that, in relation to the horizontal central axis ( 7 ) of the wall formwork ( 1 ), more anchor points be provided in the upper portion ( 8 ) of the wall formwork ( 1 ) than in the lower portion ( 9 ). Thus, the number of anchor rods to be used can be optimized.

         3 . A wall formwork for concrete structures, comprising a basic body, an outer face configured as a formwork facing, and anchor points in the form of anchor holes for the detachable connection to other wall formworks, wherein the wall formwork comprises more anchor points in one half than in the other half. 
     
     
         4 . The wall formwork according to  claim 3 , wherein the anchor points are disposed distributed over the length of the wall formwork, in particular on at least three different levels of the wall formwork, and/or wherein one or more anchor holes on the same length of the wall formwork are associated with a longitudinally spaced anchor point. 
     
     
         5 . The wall formwork according to  claim 4 , wherein an additional anchor point is disposed between a central anchor point and an anchor point, which, viewed along the length, is at the edge, preferably in such a way that the additional anchor point is provided substantially centrally between the central and the uppermost anchor points. 
     
     
         6 . The wall formwork according to  claim 1 , wherein, viewed along the length, or in the erected state, along the height, the lowermost anchor point, the central anchor point and the uppermost anchor point are disposed substantially with a uniform grid spacing relative to one another, and preferably, the wall formwork is dimensioned in such a way that the spacing of the anchor holes at the edge to the outer horizontal and/or vertical boundary of the wall formwork corresponds to half or substantially half of the grid spacing. 
     
     
         7 . The wall formwork according to  claim 1 , wherein the anchor points are disposed on at least one axis in the wall formwork that extends along the width or, in the erected state, vertically, and preferably at least three anchor holes are disposed along an axis that extends along the width or vertically. 
     
     
         8 . The wall formwork according to  claim 1 , wherein, viewed along the length, the lowermost anchor point and the uppermost anchor point are equally spaced or at least substantially equally spaced in relation to the central axis and are preferably disposed axisymmetrically. 
     
     
         9 . The wall formwork according to  claim 1 , wherein the anchor points, particularly all anchor points disposed above and on a central axis, are configured so that they can be closed, particularly by positive fit with a cap. 
     
     
         10 . The wall formwork according to  claim 1 , wherein the length or height of the wall formwork is 320 cm to 400 cm, particularly preferably 340 cm to 380 cm, and/or the width of the wall formwork is 200 cm to 280 cm, more preferably 220 cm to 260 cm. 
     
     
         11 . The wall formwork according to  claim 1 , wherein the grid spacing of the anchor points in the lower portion of the wall formwork is between 100 cm and 140 cm, more preferably 120 cm, and/or in which the vertical spacing of vertically adjacent anchor points in the upper portion of the wall formwork is between 40 cm and 80 cm, more preferably 60 cm. 
     
     
         12 . A wall formwork system comprising a plurality of wall formworks, wherein at least one wall formwork is configured according to  claim 1 , wherein the at least two wall formworks have different dimensions, in particular height and/or width. 
     
     
         13 . The wall formwork system according to  claim 12 , wherein at least one wall formwork has a height of 340 cm to 380 cm, preferably 360 cm, and at least one further wall formwork has a height of 280 cm to 320 cm, preferably 300 cm, and preferably at least two vertically spaced anchor points in the differently dimensioned wall formworks are disposed so as to be connectable for anchoring, in particular aligned with each other. 
     
     
         14 . A method for anchoring a wall formwork according to  claim 1 , wherein the vertically spaced anchor points for anchoring are chosen depending on the concreting height, in such a way that the vertical spacing of the anchor points used and, optionally, the number of anchor points used, vary. 
     
     
         15 .
