Definitions

  • the invention relates to a formwork system suitable for pouring concrete, which formwork system comprises plate-shaped formwork elements to be positioned substantially transversely to a ground surface, wherein a first set of plate-shaped formwork elements is positioned opposite a second set of plate-shaped formwork elements, substantially parallel thereto and spaced a predetermined distance therefrom.
  • the invention further relates to relates to a plate-shaped formwork element which in use is mounted in a formwork system as well as to a method for pouring concrete according to claims 11 and 13, respectively.
  • Such a formwork system which is known from Dutch patent NL1022075C2 , comprises a grid arrangement which is placed on a ground surface.
  • the grid arrangement comprises a number of rods extending in longitudinal direction and in a direction transversely thereto.
  • the known formwork further comprises plate-shaped formwork elements which, on a side facing the grid arrangement, are provided with recesses which can be positioned over the transversely extending rods.
  • the formwork elements are further oriented in vertical direction relative to the ground surface by means of pins. Opposing formwork elements are connected by means of clamps near the upper side.
  • Formwork systems are used, for example, for forming foundation beams on a ground surface prior to the construction of a building. Concrete mortar is poured into the space defined by the formwork elements for forming the foundation beams.
  • a drawback of this known formwork system is the fact that the grid arrangement and the position of the pins determine the relative positions of formwork elements located adjacent to each other. If all formwork elements have the same length, it is difficult to realise a desired length of the formwork with the known formwork system. If the formwork elements differ from each other in length, a large number of different formwork elements are required to realise a desired length.
  • the pins are furthermore required for taking up the forces exerted in transverse direction on the formwork elements by the pouring of the concrete mortar.
  • the placement and the removal of the pins is a relatively time-consuming job.
  • the object of the invention is to provide a formwork system whose dimensions are easily adjustable, in particular in longitudinal direction, whilst the forces exerted in transverse direction on the formwork elements by the pouring of the concrete mortar can be easily taken up.
  • At least two plate-shaped formwork elements of at least the first set are each provided with stiffening ribs between a bottom side of the plate-shaped formwork element, which is located near the ground surface, and an upper side of the plate-shaped formwork element, which extends parallel thereto, spaced therefrom by some distance, which stiffening ribs are located on a side of the plate-shaped formwork elements remote from the second set, wherein the two plate-shaped formwork elements, which practically abut against each other, are movable relative to each other in a longitudinal direction parallel to the ground surface.
  • the stiffening ribs which are located between the bottom side and the upper side of the plate-shaped formwork element, prevent deformation of the plate-shaped formwork elements caused by forces exerted in transverse direction during the pouring of the concrete mortar in a simple manner.
  • the stiffening ribs are located between the bottom side and the upper side of the plate-shaped formwork element, whilst it is possible to move two substantially abutting plate-shaped formwork elements in longitudinal direction relative to each other.
  • a first formwork element abuts against an outer side of a second formwork element in that situation.
  • the first formwork element can be moved in longitudinal direction relative to the second formwork element until the first formwork element abuts against the stiffening rib of the second formwork element with a transverse side thereof.
  • the first formwork element is preferably provided with a stiffening rib on a side remote from the second formwork element at the location where the first and second formwork elements overlap, which stiffening rib of the first formwork element also prevents deformation of the second formwork element, which abuts against an inner side of the first formwork element, during the pouring of the concrete mortar.
  • the formwork elements are preferably made of a metal, such as steel or aluminium, or a plastic material, such as a fibre-reinforced plastic, so that relatively thin formwork elements can be used, as a result of which the dimension of the foundation beam to be constructed will nevertheless be substantially constant in a direction transversely to the longitudinal direction in spite of the partial overlap of the formwork elements.
  • One embodiment of the formwork system according to the invention is characterised in that the stiffening ribs extend substantially transversely to the ground surface.
  • the formwork element is properly stiffened, whilst in addition the first formwork element can be moved over a relatively large distance with respect to the second formwork elements before the first formwork element abuts against a stiffening rib of the second formwork element with a transverse side thereof.
  • the plate-shaped formwork element comprises a first and a second transverse side extending transversely to the longitudinal direction, as well as at least two stiffening ribs, wherein a first of the two stiffening ribs is located near the first transverse side whilst a second of the two stiffening ribs is located near the centre between the first and the second transverse side.
  • the first formwork element can be moved over substantially half the length of the second formwork element relative to the second formwork element, so that a relatively great variation in length of the formwork system can be realised with two formwork elements.
  • Another embodiment of the formwork system according to the invention is characterised in that the stiffening ribs of the formwork elements that are located adjacent to each other can be connected to each other.
  • Another embodiment of the formwork system according to the invention is characterised in that the formwork system is provided with spacers to be positioned on a ground surface, which spacers each comprise at least two spaced-apart connecting elements, wherein the opposing formwork elements can be connected to the spaced connecting elements.
  • the spacers make it possible in a simple manner to set the spacing between opposing formwork elements in a direction transversely to the longitudinal direction.
  • Another embodiment of the formwork system according to the invention is characterised in that the plate-shaped formwork elements are detachably connected to the spacers.
  • the spacers are covered by the concrete mortar.
  • the plate-shaped formwork elements can be disconnected from the spacers to be reused for a formwork system to be installed elsewhere.
  • Another embodiment of the formwork system according to the invention is characterised in that the spacer is strip-shaped, wherein the connecting elements are U-shaped.
  • the plate-shaped formwork elements can be simply placed in the U-shaped connecting elements with a bottom side thereof.
  • two overlapping parts of the formwork elements fit in a U-shaped connecting element as well. Because of said U-shape, the formwork elements can be easily removed from the connecting elements.
  • Another embodiment of the formwork system according to the invention is characterised in that the plate-shaped formwork element is provided with a flange that extends in longitudinal direction, parallel to the ground surface, which flange can be positioned in the U-shaped connecting element of the spacer.
  • the flange will extend in a direction away from the space present between the formwork elements.
  • the flange enables the - preferably relatively thin - formwork element to stand unsupported, so that no additional measures are needed for supporting the formwork element temporarily during the installation of the formwork system.
  • the flange provides a stiffening of the formwork element at the bottom side thereof.
  • formwork elements as well as at least one elongate slat can be detachably positioned in adjacent U-shaped connecting elements of the spacers, which elongate slat is located on the side of the formwork elements that is provided with the stiffening ribs.
  • the dimensions of the formwork element, the slat and the U-shaped connecting element are preferably such that after the formwork element and the slat have been placed into the U-shaped-connecting element, the slat will provide an adequate clamping of the formwork element in the U-shaped connecting element.
  • the slat is made of wood, for example, and preferably extends over a number of formwork elements. Deformation of the formwork elements during the pouring of the concrete mortar is prevented in a simple manner also by the slat. If the formwork element is provided with a flange, the slat will preferably be positioned on the flange, so that an additional clamping of the formwork element in the U-shaped connecting element is obtained.
  • the formwork element can be easily removed from the U-shaped connecting element. If the flange has a width which is smaller than a spacing between legs of the U-shaped connecting element, the formwork element abutting against one leg can easily move in the direction of the other leg, so that the formwork element will come free from the poured concrete mortar.
  • the formwork system comprises U-shaped brackets to be positioned over opposing formwork elements on a side remote from the ground surface, wherein each U-shaped bracket is provided with U-shaped holders, wherein at least one slat can be detachably positioned in adjacent U-shaped holders of the U-shaped brackets.
  • the slat is made of wood, for example, and preferably extends over a number of formwork elements. Deformation of the formwork elements during the pouring of the concrete mortar is prevented in a simple manner also by the slat that is positioned at the upper side of the formwork elements.
  • the invention also relates to a plate-shaped formwork element suitable for a formwork system as claimed in claim 11 and as described above, which plate-shaped formwork element is provided with stiffening ribs which extend at least partially transversely to a longitudinal direction of the plate-shaped formwork element.
  • the invention also relates to a method for pouring concrete, wherein a formwork system as described above is placed on a ground surface, plate-shaped formwork elements are moved relative to each other to a desired relative position, concrete mortar is poured into a space defined by formwork elements of the formwork system, after which the formworlc system is at least partially removed.
  • any desired length of the formwork system can be realised in a simple manner without there being a need to produce the individual formwork elements to size.

  • the formwork system 1 shown in figure 1 comprises four sets 2, 3, 4, 5 of plate-shaped formwork elements 6, 7.

  • the formwork element 7 is largely similar to the formwork element 6.
  • the difference between the formwork element 7 and the formwork element 6 is that in the case of the formwork element 6 the first stiffening rib 20 is located near the second transverse side 13 rather than near the first transverse side 12.
  • the second stiffening rib 11 is located near the centre, between the first transverse side 12 and a second transverse side 13 of the plate-shaped part 8.
  • the formwork system 1 shown in figure 1 further comprises angle-shaped formwork elements 21, 22 which, as is clearly shown in figures 4 and 5 , are provided with plate-shaped parts 8 that extend transversely to each other.
