Definitions

  • the invention relates to a wall formwork according to the preamble of claim 1, a wall formwork system equipped with such a wall formwork and a method for anchoring such a wall formwork.
  • a wall formwork within the sense of the present invention is used in formwork engineering for concrete structures, i.e. for concreting concrete or reinforced concrete structures.
  • a wall formwork is typically used for producing formworks for walls, columns, foundations, shafts or the like.
  • a wall formwork comprises a formwork facing on the front facing towards the concrete and elements supporting the formwork facing on the back, such as frames, longitudinal beams and crossbars.
  • the two sides of a wall to be concreted are delimited by wall formworks.
  • the outer face of each wall formwork configured as a formwork facing in that case adjoins the concrete.
  • Wall formworks facing each other are, as a matter of principle, retained by a plurality of anchor rods.
  • the anchor rods are in this case pushed through openings - so-called anchor holes - in the wall formworks, and attached at their ends to the elements supporting the respective formwork facing in such a way that at least the tensile force acting upon the anchor rods during concreting is absorbed, but preferably also a compressive force.
  • Wall formworks are exposed to loads due to the concrete pressure, which rises together with the height of a wall to be concreted. Wall formworks, anchor systems and the number of anchor systems used must be designed accordingly.
  • the preparation of a wall formwork entails the problem that reliable anchoring is to be made possible by a corresponding arrangement of the anchor points in the wall formwork. At the same time, it is necessary to be able to reliably absorb the concrete pressures occurring in a wall formwork in each case.
  • the arrangement of the anchor points in conventional wall formworks is optimized, in particular, for a given maximum load, so that flexible forming is not possible, and the resulting expenditure for a rational assembly or dismantling of the wall formworks is unsatisfactory.
  • F 1 011 770 A discloses a formwork comprising a distribution of anchor holes which allow flexible corner connections.
  • a wall formwork for concrete structures which allows a flexible anchoring of the anchor points depending on the arising concrete pressure.
  • the object of the invention is achieved by a wall formwork having the features of one of the independent claims. Advantageous embodiments are apparent from the dependent claims.
  • a wall formwork is proposed in which more anchor points are disposed in one half of the wall formwork than in the other half.
  • Such a wall formwork is intended and suitable for erecting it in such a way that, in relation to the horizontal central axis, there are more anchor points in the upper portion of the wall formwork than in the lower portion.
  • the anchor points are provided in an asymmetrical manner in the upper and lower portions of the wall formwork, in such a way that, in the mounted state, more anchor points are provided in the upper portion than in the lower portion.
  • a specific anchoring can then take place.
  • the concrete pressure varies in the process depending on the concreting height of a wall formwork.
  • anchor points - in the form of anchor holes - are chosen depending on the concreting height, particularly in such a way that the vertical spacing of the anchor points used, and preferably the number of anchor points used and disposed vertically spaced, varies, depending on the load-related situation.
  • the number of anchor rods to be inserted, and thus the assembly expenditure and dismantling expenditure can thus be advantageously minimized.
  • the number of different wall formworks can also be minimized in this manner.
  • Anchor holes that are not required are closed with a cap, preferably by positive fit. For closure, the cap is connected with the anchor hole for instance by screwing or by latching. If a low concreting height is required, the use of a reduced number of vertically spaced anchor points suffices for reliably anchoring a wall formwork.
  • the anchor points in the form of anchor holes are chosen in such a way that at least one anchor point from the lower portion and at least one anchor point from the upper portion are used for anchoring. Therefore, an anchor point above the horizontal central axis is used as an anchor point from the upper portion.
  • an anchor point above the horizontal central axis is used as an anchor point from the upper portion.
  • it is sufficient if, seen in the vertical direction, only two of, as a rule, four anchor points provided in the vertical direction are used for anchoring if the concrete pressure is relatively low.
  • anchor points are used for anchoring, i.e. typically three anchor points.
  • the wall formwork typically has four anchor holes along the height direction, i.e. in the vertical direction.
  • this wall formwork is anchored in such a way that it is capable of withstanding the increased loads over the entire height of the wall formwork.
  • the anchor points used are, in particular, disposed in such a way that they are uniformly distributed over the height of the wall formwork in order to enable a particularly load-adapted construction of the wall formwork. Among one another, they then have identical spacings.
  • the structure according to the invention of the wall formwork therefore enables flexible anchoring, which can be individually and specifically adapted to the loads and at the same time permits a rational assembly of the wall formwork.
  • wall formworks can optionally be used for the fabrication of walls with a low height and with a height that, in comparison, is great, without always having to use all the anchor holes for anchoring, i.e. fitting them with anchors. Therefore, it is unnecessary to have different wall formworks in store for this purpose. The number of parts to keep in store can thus be advantageously minimized.
  • a wall formwork with such an arrangement of anchor points can be combined in an improved manner with other, differently designed wall formworks.
  • the additionally provided anchor point in the upper portion of the wall formwork contributes to an improved capability of the wall formwork according to the proposal of being combined with differently dimensioned wall formworks.
  • the arrangement of the additional anchor point in the upper portion is designed in such a way that, through it, the wall formwork can be connected to a differently dimensioned wall formwork. This increases the compatibility of the wall formwork, so that the wall formwork can be combined with other wall formworks in a variety of ways.
  • the anchor points which are not provided symmetrically, are preferably disposed asymmetrically distributed over the height of the wall formwork, i.e., in particular, on at least three vertically spaced levels of the wall formwork. Height means the length of a wall formwork or formwork facing.
  • a vertically spaced anchor point can comprise one or more anchor holes at the same level, i.e. height, of the wall formwork.
  • anchor holes there are four anchor holes, respectively, along the height, and two anchor holes, respectively, along the width.
  • one or more anchor holes are located on the center line that separates the upper half of the wall formwork from the lower. This embodiment permits an optimized usage of the entire height of the wall formwork.
  • an anchor point is disposed between the central anchor point and the upper anchor point, preferably in such a way that the anchor point is provided centrally or substantially centrally between the central and the uppermost anchor points.
  • the vertically spaced anchor points comprise several anchor hole at the same level of the wall formwork, i.e. two or three, as a rule.
  • the central anchor point, the uppermost anchor point as well as the interposed additional anchor point can each comprise two anchor holes at the same level of the wall formwork, which in the erected state are horizontally spaced apart.
  • This arrangement of the anchor points with anchor holes distributed across the width of the anchor holes ensures a particularly reliable anchoring of large-surface wall formworks.
  • a flexible anchoring of the wall formwork can be carried out at the same time by specific selection of the vertically spaced anchor points, in order to make possible an efficient and reliable anchoring.
  • the additional anchor point in the upper portion of the wall formwork disposed between the central and uppermost anchor points is used particularly in combination with the lowermost anchor points at relatively low concrete pressures, i.e. primarily at concrete pressures that are reduced with respect to the height of the wall formwork.
  • the arrangement of the corresponding anchor points is designed, in particular, in such a way that the loads arising can be securely absorbed by means of two vertically spaced anchor points, particularly by means of the lowermost anchor point and the additional anchor point in the upper portion of the wall formwork. Due to the number of anchor points used, which in comparison with a conventional anchoring is reduced, the assembly-related expenditure can be reduced, so that an efficient assembly or dismantling of a wall formwork is made possible.
  • the lowermost anchor point, the central anchor point and the uppermost anchor point are disposed with substantially a uniform grid spacing.
  • the wall formwork is preferably 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 substantially corresponds to half of the grid spacing.
  • the additional anchor point in the upper portion of the wall formwork is preferably disposed in such a way that the vertical spacing to the vertically adjacent anchor points largely corresponds to half of the grid spacing.
  • the anchor points in the lower portion have a vertical spacing corresponding to the grid spacing
  • the anchor points in the upper portion of the wall formwork have a vertical spacing corresponding to half of the grid spacing.
  • This arrangement of the anchor points improves the load- adapted structure of the wall formwork. This is particularly advantageous in the case of increase loads on the wall formwork, for example due to relatively high concreting heights, such as, for example, concreting heights that approximately or largely correspond to the height of the wall formwork. Such an arrangement of the anchor points contributes to the capability of the wall formwork of being exposed to loads substantially uniformly over the height in this way.
  • the anchor points are disposed in the form of anchoring holes on at least one vertically extending axis.
  • at least three anchor holes are provided on a vertically extending axis. It is particularly advantageous to provide anchor holes on two vertically extending axes. In that case, two horizontally spaced anchor holes on a common level, i.e. height, of the wall formwork can be associated with a vertically spaced anchor point. Providing horizontally spaced axes with anchor holes enables a correspondingly large-surface and rugged configuration of wall formwork.
  • the lowermost anchor point and the uppermost anchor point are equally spaced in relation to the horizontal central axis and disposed preferably axisymmetrically. It is particularly advantageous to provide a central anchor point on the horizontal central axis.
  • the symmetrical arrangement of the lowermost and uppermost anchor points in relation to the horizontal central axis contributes to the capability of the wall formwork of uniformly absorbing the loads. I ⁇ is particularly advantageous to configure the anchor points of the wall formwork, particularly all anchor points disposed above and on the horizontal central axis, so that they can be closed.
  • the anchor points are capable of accommodating a closure means in a sealing manner in order to prevent concrete from leaking from the wall formwork.
  • Anchor points that are not required for anchoring can in that case be securely closed as required.
  • the anchor holes are configured in such a way that the closure means is accommodated so as to end flush with the formwork facing and that thus, there is no projecting portion of the closure means in the formwork facing. Consequently, the solidified concrete has a largely smooth surface. In this way, visible impressions of closed anchor points are avoided so that the wall formwork can be used in an advantageous manner, from a production standpoint, for preparing visually attractive exposed concrete.
  • the anchor holes at the edge have a spacing of at least 20 cm, more preferably at least 40 cm, to the horizontal and/or vertical boundary of the wall formwork.
  • anchor holes at the edge are those anchor holes that adjoin the outer horizontal and/or vertical boundary of the wall formwork in at least one direction. This ensures that sufficient space is available at the anchor holes at the edge to provide a secure anchoring by means of anchor rods.
  • Particularly preferred dimensions of the wall formwork according to the proposal are formats having a width of 200 cm to 280 cm, more preferably 220 cm to 260 cm, and/or a height of 320 cm to 400 cm, more preferably 340 cm to 380 cm.
  • a wall formwork system comprising a plurality of wall formworks, wherein at least two wall formworks have different dimensions, in particular height and/or width.
  • At least one wall formwork corresponds to the wall formwork according to the proposal explained above, so that in this regard, reference may be made to the statements above in their entirety.
  • the formwork system makes it possible to combine the wall formworks in a flexible manner.
  • the configuration of the wall formworks and the dimensioning of the dimensions is designed in such a way that differently dimensioned wall formworks can also be disposed in a standing, lying, vertically and/or laterally offset manner relative to one another, in order to enable, in a variety of ways, the stacking of a wall formwork for preparing a large-surface formwork.
  • the arrangement of the anchor points is in that case designed in such a way that at least two vertically spaced anchor points in the respective wall formworks can be connected to each other.
  • the connectable anchor points in the respective wall formworks are disposed so as to be aligned with each other. This ensures the compatibility between wall formworks with different heights, so that a variety of combinations of different formats of wall formworks is made possible.
  • the invention moreover relates to a system of wall formworks, comprising a wall formwork according to the claim, as well as a wall formwork with a smaller length or height with symmetrically distributed anchor holes, which are disposed along its length in the same way as anchor holes of the wall formwork according to the claim.
  • the anchor holes are symmetrically distributed, they have a uniform or at least substantially uniform grid spacing relative to each other, the wall formwork advantageously being dimensioned in such a way that the spacing of the anchor holes to the outer boundary of the wall formwork, which in the erected state extends vertically and/or horizontally, corresponds to half of the grid spacing or at least substantially half of the grid spacing.
  • the anchor holes are disposed in a uniform, i.e. substantially equally spaced-apart grid spacing relative to each other in order to optimize the wall formwork with regard to the arising concrete pressure. In the process, the spacing of the anchor holes to the outer boundary of the wall formwork is also set in a specific manner.
  • a wall formwork is prepared with wall formworks of this type and filled with concrete, it is thus ensured that the wall formwork is exposed to the load particularly uniformly, in such a way that the loads are substantially evenly distributed across the arrangement of the anchor holes.
  • the arrangement which is, in particular, symmetrical, contributes to the concrete forces arising being absorbed in a uniformly distributed manner across the anchor holes. Excessive loads, and thus the danger of damage to the wall formwork, particularly in the region of the anchor holes and the anchor points, are thus avoided in an improved manner, so that an overall improved durability of the wall formwork is achieved.
  • the arrangement of the anchor holes moreover contributes to preparing a rugged formwork in a manner that is advantageous as regards the assembly with few anchor holes, and thus, also few anchor points. The fewer anchor rods have to be used, the smaller the expenditure for assembly and dismantling.

  • Fig. 2 shows lateral views of a wall formwork with a comparison of the courses of the concrete pressures given different anchorings
  • Fig. 3 shows a wall formwork system.
  • the wall formwork 1 according to the proposal, which is depicted in the drawing, comprises an outer face configured as a formwork facing 6 as well as a basic body.
  • the basic body comprises a profile-shaped frame structure 18, which further preferably consists of longitudinal beams and crossbars for improved stiffening.
  • the basic body is preferably made from metal, in particular light metal.
  • the basic body can be made from hot-dipped galvanized steel or extruded light metal.
  • the anchor points in the form of anchor holes 2, 3, 4, 5 are disposed distributed over the height 10 of the wall formwork, i.e. at different levels, i.e. heights of the wall formwork 1, with the upper portion 8, i.e. the one half, of the wall formwork having more anchor holes than the lower portion 9, i.e. the other half.
  • the arrangement of the anchor points is designed in such a way that, depending on the arising loads in a wall formwork, anchor points can be specifically used in order to obtain a reliable anchoring even under difficult boundary conditions such as high concrete pressures.
  • the anchor points are disposed in the form of anchor holes along two vertically extending axes.
  • An anchor point at a certain level, i.e. height, of the wall formwork 1 comprises - as is apparent from Fig. 1 - two horizontally spaced anchor holes at the same height of the wall formwork.
  • the vertically spaced anchor points in the form of anchor holes also extend across the width 11 of the wall formwork.
  • an anchor point is provided on the horizontal central axis 7.
  • two horizontally spaced anchor holes are associated with the central anchor point 3.
  • the wall formwork 1 comprises an uppermost anchor point 5 in the upper portion 8 and a lowermost anchor point 2 in the lower portion 9 of the wall formwork 1, with the uppermost anchor point 5 and the lowermost anchor point 2 being disposed substantially equally spaced, i.e., in particular, axisymmetrically, in relation to the horizontal central axis 7.
  • Another anchor point 4 is provided between the uppermost anchor point 5 and the central anchor point 3 as an additional anchor point in the upper portion 8 of the wall formwork.
  • the additional anchor point 4 with two horizontally spaced anchor holes 4 is disposed centrally between the uppermost anchor point 5 and the central anchor point 3.
  • the vertical spacing of the additional anchor point 4 to the vertically adjacent anchor points is in that case largely identical.
  • the additional anchor point 4 in the upper portion 8 of the wall formwork can expediently be used as an optional anchor point of a wall formwork. This makes it possible to adapt the anchoring of the wall formwork 1 specifically to the arising loads and to thus keep the overall assembly-related expenditure small.
  • the concreting height in the majority of applications for example in about 70% of cases of application, regularly corresponds to no more than 3/4 of the height 10 of the wall formwork, or no more than 240 cm. Due to the reduced loads, it is advantageous in this case to reduce the number of anchor points used that are disposed distributed over the height 10 of the wall formwork.
  • an anchor point from the lower portion 9, i.e. the anchor point 2, and an anchor point from the upper portion 8 are used, with the additional anchor point 4 between the uppermost anchor point 5 and the central anchor point 3, in particular, being used as the anchor point from the upper portion. This ensures - in manner yet to be explained - a favorable concrete pressure course in a wall formwork.
  • the concreting height corresponds to more than 3/4 of the height 10 of the wall formwork, or more than 240 cm. Due to the increased loads, it is in this case advantageous to use a greater number of vertically spaced anchor points for anchoring.

In this way, the loads in the case of a reduced concreting height of a wall formwork can be reliably absorbed by a smaller number of vertically spaced anchor points, so that, in this respect, the assembly-related expenditure is reduced. This contributes to an efficient assembly or dismantling of the wall formwork.
  • At least two vertically spaced anchor points of a wall formwork 1 according to the proposal are disposed in such a way that they can be connected to a differently dimensioned wall formwork, in particular with a different height and/or width.
