Definitions

  • the invention relates to formwork elements having a formwork skin, having a frame bearing the latter, and having struts which are arranged within the frame and support the formwork skin.
  • the invention also relates to a formwork construction kit which comprises such formwork elements and from which formworks of a wide variety of kinds can be formed.
  • Such formwork elements are already known from practice in a wide variety of embodiments and are used, for example, in concrete formwork construction.
  • the formwork elements On account of the loadings to which such formwork elements are subjected, it is necessary for the formwork elements to be configured to be robust. This is accompanied as a rule with a comparatively high weight of the formwork elements, which can make handling of such formwork elements more difficult.
  • a formwork element having one or more of the features described herein.
  • the frame of the formwork element is produced from unprofiled flat steel and that the struts of the formwork element are produced from open sectional steel.
  • an open sectional steel is such a sectional steel which has an open cross section.
  • the struts consisting of sectional steel have the advantage that the contact points of the struts on the formwork skin are removed further away from one another.
  • the struts can be arranged to be somewhat further removed away from one another than is possible in the case of previously known formwork elements of the type stated at the outset, although, in spite of the greater distance of the struts from one another, a comparable or even higher loadability and stability of the formwork element can be achieved than for the previously known formwork elements.
  • the use of struts which are produced from sectional steel allows the total weight of the formwork element to be reduced by comparison with previously known formwork elements of comparable size. Overall, there is thus created a formwork element which offers a good compromise between highest possible loadability and low intrinsic weight.
  • struts consisting of open sectional steel can be coated, for example with a corrosion protection, relatively simply on all sides. It is thus possible with comparatively little effort to improve corrosion resistance of the formwork element equipped with these struts.
  • Unprofiled flat steel can, for example, be characterizable by the fact that production with cylindrical rolls is possible.
  • the struts are arranged in such a way that the sectional steel is open to the formwork skin. In this way, a head side and/or a head part of the respective strut can be used for fastening.
  • the sectional steel has a symmetrical profile, in particular a hat profile.
  • the use of a sectional steel with symmetrical profile can promote an advantageous stress distribution on the strut. If the profile of the sectional steel of the struts is a hat profile, the struts offer support surfaces against which the struts bear flat against the formwork skin and/or which can be used, for example, for fastening by rivets to prepunched holes.
  • the sectional steel can have at least one longitudinal bead on its head side.
  • a fastening element which is intended to be secured to the strut can engage behind this longitudinal bead and thus be secured to the strut in a rotationally fixed manner.
  • a formwork element of the type stated at the outset which has additional features as disclosed herein.
  • this formwork element is that an even number of struts is arranged within the frame, of which two outer struts each have at least one plug-through opening for an anchor. These plug-through openings define so-called anchor points of the formwork element.
  • the struts are arranged in a uniformly distributed manner within the frame, it is possible to mount accessory parts on any desired struts.
  • the formwork element can thereby obtain a certain symmetry which simplifies its handling and in particular its orientation in use.
  • the resulting advantage is that anchor points defined by the plug-through openings of the at least two outer struts are automatically arranged in 1 ⁇ 5 of the total length or total height of the formwork element.
  • This distance from the edge of the formwork element and/or frame defines a position of an anchor on the formwork element that is particularly favorable with regard to the occurring loads and with regard to the desired stress distribution.
  • the plug-through openings defining the anchor points are here preferably provided in the edge vicinity of the frame or of the formwork element.
  • the arrangement of plug-through openings in the struts has the advantage, in the case of such struts which are produced from sectional steel, that the sectional steel simultaneously also offers a support for a plate or washer by means of which the anchoring holds the formwork skin and ultimately also the formwork element. This is particularly important in order to prevent a situation in which a formwork element, which is adjacent in the use position of the formwork element and preferably has the same design and in which, however, no anchor is used, is pressed out of its position by the pressure of poured-in concrete and thereby pivots said plate or washer.
  • a formwork element of the type stated at the outset that has further features as discussed herein.
  • at least one strut has at least two plug-through openings, wherein a shortest distance between a first plug-through opening of the at least two plug-through openings and the frame of the formwork element is shorter than a shortest distance between a second plug-through opening of the at least two plug-through openings and the frame. This allows the selective use of the formwork element in a vertical or horizontal position.
  • the plug-through openings define, for the anchors, anchor points of the formwork element.
  • the anchor points which are arranged close to the edge of the formwork element, that is to say at a smaller distance from the frame of the formwork element, can as a rule not be used for anchoring in the horizontal position of the preferably rectangular formwork element. It is frequently the case namely that separating plates or separating elements are cast into a foundation of a building structure on which further walls are intended to be produced with the aid of formwork elements.
  • separating plates or separating elements serve to close joins or gaps between the wall, which is to be newly cast on the foundation, and the foundation.
  • the separating plates or separating elements have already been introduced during production of the foundation, they interfere in principle with the setting of anchors in the case of horizontal formwork elements.
  • the second plug-through opening whose distance from the frame is greater than the distance between the first plug-through opening and the frame, in the case of the formwork element according to the invention there is at least one plug-through opening available which, with a probability bordering on certainty, remains reachable for setting an anchor or anchor bar even when the formwork element is used or arranged horizontally. This is even the case when a separating plate or separating element has been cast in the aforementioned manner in the foundation of the building structure to be produced.
  • a formwork skin having a thickness of 12 mm can be used. It should be mentioned in this connection that the formwork skin can be produced, for example, from plywood. It is possible for the formwork skins for the formwork elements to be produced in various thicknesses. Thus, it is possible to provide a range of formwork elements of the type stated at the outset that differ from one another in terms of their formwork skins. It is possible here, for example, in a formwork element of the range of formwork elements, to use a formwork skin having a thickness of 12 mm, whereas another formwork element from the range of formwork elements can have a formwork skin having a thickness of, for example, 15 mm.
  • two or four struts are arranged within the frame of the aforementioned formwork elements.
  • the use of four struts, which are preferably uniformly distributed within the frame is particularly advantageous, since the struts are then arranged in such a way that the plug-through opening arranged in the two outer struts of the total of four struts here are arranged, with respect to at least one side of the frame and/or of the formwork element, in a position which corresponds to 1 ⁇ 5 and/or 4 ⁇ 5 of the length of this side.
  • the formwork elements there is provision that the, in particular two or four, struts are oriented parallel to one another and/or spaced uniformly apart from one another. This gives a symmetrical design of the formwork element formed in such a way, which in turn can simplify the handling and the orientation of the formwork elements in practice.
  • the aforementioned struts of the formwork elements can be produced from a sectional steel which has a trapezoid profile.
  • the struts can thus have a trapezoidal cross section.
  • the frame of the formwork elements has a side ratio of 3 to 5. This is particularly advantageous, in particular in connection with the formwork element according to the third independent patent claim, since there thus automatically results a situation in which the plug-through openings for anchors that are used for horizontal mounting or for horizontal use of the formwork element are situated on 1 ⁇ 3 of the total height of the formwork element and thus also remain accessible for anchoring in the case of separating plates which are cast into a foundation. It is particularly favorable if a formwork element with these dimensions has four struts which are arranged in a uniformly distributed manner and has two uniformly distributed plug-through openings on a strut, since consequently—independently of the orientation of the formwork element—a uniform arrangement of the anchor bars can be achieved.
  • All of the above-described formwork elements preferably take the form of manually transportable formwork elements which can be carried by two persons. There can thus be achieved an intrinsic weight of the formwork elements of 50 kg or less.
  • the formwork element preferably has handles for this purpose.
  • the formwork element has at least one additional strut.
  • This additional strut can be arranged or oriented transversely or at right angles to at least one strut of the formwork element.
  • the formwork element has at least one additional strut, in particular such an additional strut which is arranged transversely or at right angles to at least one strut of the formwork element, which has at least one holding handle and/or the at least one holding opening.
  • at least one strut of the formwork element/of the aforementioned formwork elements has at least one holding handle and/or at least one holding opening.
  • holding handles and/or holding openings are formed on two mutually opposite sides. Carrying by two persons can thus be made possible, in particular for an intrinsic weight of 50 kg or less.
  • all of the aforementioned holding handles and/or holding openings of the formwork element can be designed for fastening a load receptacle which in turn is suitable for crane transport of the formwork element.
  • the aforementioned at least one load receptacle can be a constituent part of the formwork element. In this way, there is avoided an additional element and/or an additional handling step when using a formwork element configured in such a manner.
  • the frame of the aforementioned formwork elements can have, for example, a height of 75 mm or less. Furthermore, it should be noted that an inner construction of the frame, which consists of the struts of the formwork element and the formwork skin, can have overall a height which corresponds to the height of the frame or is less than the height of the frame.
  • the formwork skin does not project beyond the frame. It is thus possible to achieve a flush arrangement of the formwork skin on the frame of the formwork element that prevents a situation in which formwork elements constructed in such a way catch when they are stacked for transport or for storage. Thus, damage to the stacked formwork elements can be avoided. Furthermore, it can be expedient to avoid the formwork skin projecting beyond the frame since, when using a plurality of formwork elements above one another, reinforcements in the form of laths are mounted from outside and should lie both on the struts of the respective formwork element and on the frame of the formwork element.
  • the formwork element can have a frame with a square basic shape. In another embodiment, the formwork element can have a frame with a non-square and/or rectangular basic shape. A rectangular formwork element can thus result. Particularly in the case of rectangular formwork elements, the struts can be oriented along a short side of a rectangular basic shape of the frame of the formwork element.
  • the frame is formed in a projection-free manner on the inner side. It is advantageous here that the flat steel does not have to be provided with additional structures. This can save costs in the production.
  • the frame preferably has punched connection openings.
  • the formation of punched connection openings is advantageous particularly for relatively small piece numbers with respect to the use of sectional steel, because no rolling tools have to be purchased.
  • connection openings It is particularly favorable if at least two different types of connection openings are formed. Fastening possibilities of different types can thus be formed.
  • connection opening transversely to the formwork skin is chosen to be corresponding.
  • an orientation of the formwork skins with respect to one another transversely to their extent can be defined independently of which connection openings are chosen.
  • connection openings takes the form of an oblong hole.
  • connection openings takes the form of a round hole.
  • An oblong hole can here, for example, be characterized in that a connection means, for example a plug-through bolt, which can be placed in a play-free manner in the oblong hole in a transverse direction or narrow direction, has play in a longitudinal direction.
  • a round hole can here, for example, be characterized in that a connection means, for example a plug-through bolt, which can be placed in a play-free manner in the oblong hole in a transverse direction, likewise has no play in a longitudinal direction.
  • the struts are formed identically to one another.
  • a part number for production of formwork elements can be reduced and tool costs can be reduced.
  • Formation of additional plug-through openings for anchor bars is also able to be facilitated, since the struts do not necessarily have to be post-machined.
  • the invention allows the provision of a formwork construction kit according to the independent claim directed to such a one, which comprises at least two types of different formwork elements of the above-described type.
  • the formwork kit can favor the production of so-called light formworks, in particular when an intrinsic weight of the formwork elements is in each case 50 kg or less.
  • the use of this formwork construction kit has the advantage that a crane for building up and/or dismantling a formwork which is formed with the formwork construction kit is not absolutely necessary. This can save time and costs.
  • two intersecting lines of plug-through openings of a first type of formwork elements can be matched in their positions, that is to say for example with respect to a height in relation to a setting-up surface in the respective use position, with a line of plug-through openings of a second type of formwork elements.
  • anchor bars can be placed at a uniform height, in particular with two different orientations of the first type of formwork elements. This is particularly favorable in the processing of facing concrete, since there then results a uniform image of the (closed) holes with respect to the anchor bars.
  • connection clamp is present in the formwork construction kit.
  • the formwork elements can be connected to one another in a simple manner on the unprofiled frames.
  • holding projections on clamp arms of the connection clamp are designed to fit with connection openings in the frame of the formwork elements. The connection clamps can thus be prevented from sliding off.
  • the invention further allows the use of a connection opening in a frame of a formwork element, in particular as described above and/or according to one of the claims directed to a formwork element, for selectively fastening a connection clamp and a plug-through bolt for connecting the formwork element to a further formwork element.
  • a connection opening in a frame of a formwork element in particular as described above and/or according to one of the claims directed to a formwork element, for selectively fastening a connection clamp and a plug-through bolt for connecting the formwork element to a further formwork element.

  • the struts 4 of the formwork elements 1 obtain a higher stiffness, in relation to the material used for producing the struts 4 , than those struts which are used in previous formwork elements and are produced from unprofiled flat steel.
