Definitions
- the invention relates to formwork elements with a
- Formwork skin with a frame supporting these and with
- Struts that are arranged within the frame and support the formwork skin.
- the invention also relates to a modular formwork system which comprises such formwork elements and which can be formed from the most diverse types of formwork.
- the object of the invention is therefore to provide formwork elements of the type mentioned above, the
- the frame of the formwork element be made of unprofiled flat steel and the struts of the formwork element made of open profile steel are made.
- An open profile steel for example, can be regarded as a profile steel that has an open
- the struts made of profile steel have the advantage over struts made of flat steel that the contact points of the struts on the formwork skin are further apart. This way, the
- Struts are arranged a little further away from each other than is possible with previously known formwork elements of the type mentioned, with a comparable or even higher load capacity and stability of the formwork element as with the previously known formwork elements can be achieved despite the greater distance between the struts. Furthermore, by using
- equipped formwork element can be improved with comparatively little effort.
- Unprofiled flat steel can, for example, thereby
- the struts are arranged so that the profile 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. It is also possible that the profile steel has a symmetrical profile, in particular a hat profile. The use of a profile steel with a symmetrical profile can promote an advantageous stress distribution on the strut. If the profile of the steel profile of the struts is a hat profile, the struts provide contact surfaces on which the
- Struts lie flat against the formwork skin and / or the e.g. can be used for fastening by riveting to pre-punched holes.
- the profile steel can on its head side at least one
- a fastening element that is to be attached to the strut can grip behind this longitudinal bead and thereby non-rotatably on the strut
- a formwork element of the type mentioned at the outset is also proposed, which has the features of the second independent claim directed to such a formwork element.
- an even number of struts be arranged within the frame, of which two outer struts each have at least one push-through opening for an anchor. These through openings define so-called anchor points of the formwork element.
- Struts are evenly distributed within the frame, it is possible to mount accessories on any struts.
- the formwork element can thereby be given a certain symmetry, which simplifies its handling and, in particular, its alignment during use.
- Frame are arranged evenly distributed, there is the advantage that of the through openings of the at least two external struts defined anchor points are automatically arranged at 1/5 of the total length or total height of the formwork element. This distance to the edge of the formwork element and / or frame defines one with regard to the loads that occur and the desired ones
- the through openings defining the anchor points are preferably in the vicinity of the edge of the frame or the
- Struts made from sectional steel have the advantage that the sectional steel also offers a support for a plate or washer with which the anchoring holds the formwork skin and ultimately also the formwork element. This is particularly important in order to prevent a formwork element, which is adjacent in the position of use of the formwork element, preferably of the same construction, but in which no anchor is used, from being caused by the pressure of
- Formwork element of the type mentioned proposed that at least one bracing at least two
- Push-through openings to the frame of the formwork element is shorter than a shortest distance between a second push-through opening of the at least two push-through openings and the frame. This enables the formwork element to be used either in a standing or lying position.
- Formwork element that is to say arranged at a smaller distance from the frame of the formwork element, can generally be in the horizontal position of the preferably rectangular
- Formwork element cannot be used for anchoring.
- dividing sheets or dividing elements are often cast into a foundation of a building on which further walls are to be produced with the aid of formwork elements. These dividing plates or dividing elements are used to close joints or gaps between the wall to be re-poured on the foundation and the foundation. Since the dividers or
- the second push-through opening the distance of which from the frame is greater than the distance of the first push-through opening to the frame, at least one push-through opening is available in the formwork element according to the invention, which with security
- Embodiment of a formwork element the features of the formwork elements described above, to which in particular one of the independent claims 1 and 2 or both are directed, can be used in a meaningful way.
- These several push-through openings can be provided in different struts of a formwork element in one direction at the same height and / or at the same distance from the frame.
- the anchor points defined by the push-through openings continue to be at the same height when the shuttering element is rotated by 90 °.
- This has an aesthetic advantage since the corresponding anchor points recognizable on the finished component are then aligned with one another in the poured concrete.
- a formwork skin with a thickness or thickness of 12 mm can be used.
- a formwork skin with a thickness or thickness of 12 mm can be used.
- Formwork skin can be made of plywood, for example. It is possible to use the formwork skins for the
- formwork elements of the type mentioned which differ from one another by their formwork skins.
- a formwork element Series of formwork elements a formlining with a thickness or thickness of 12 mm can be used, while another formwork element from the series of
- Formwork elements can have a formwork skin with a thickness of, for example, 15 mm.
- Formwork elements are arranged two or four struts.
- the use of four struts, preferably evenly distributed within the frame, is particularly advantageous since the struts are then arranged in such a way that the total of four struts arranged here are in the two outer struts
- Frame and / or the formwork element are arranged in a position that corresponds to 1/5 and / or 4/5 of the length of this side.
- Struts are aligned parallel to one another and / or are evenly spaced from one another. This gives a symmetrical structure of the one so designed
- Formwork element which in turn, the handling and the
- Alignment of the formwork elements can simplify in practice.
- the aforementioned struts of the formwork elements can be made of a profile steel that has a trapezoidal profile.
- the struts can therefore have a trapezoidal cross-section.
- Formwork elements has an aspect ratio of 3 to 5. This is particularly advantageous, especially in connection with the formwork element according to the third independent
- Claim because it automatically results that the through openings for anchors used for a horizontal installation or for a horizontal use of the formwork element are at 1/3 of the total height of the formwork element and thus remain accessible for anchoring even with separating plates cast in a foundation. It is particularly favorable if a formwork element with these dimensions has four evenly distributed struts and two evenly spaced through openings on one strut, since thus - regardless of the orientation of the
- Formwork element - a uniform arrangement of the tie rods can be achieved.

- Handles and / or holding openings are preferably formed on two opposite sides. This means that it can be carried by two people, in particular with a dead weight of 50 kg or less.
- Crane transport of the formwork element is suitable.
- the aforementioned at least one load pick-up can be used in a
- an internal structure of the frame which consists of the struts of the formwork element and the formwork skin, can have a total height that corresponds to the height of the frame or is less than the height of the frame.
- the internal structure corresponds to the height of the frame
- Formwork skin not over the frame. In this way, a flush arrangement of the formwork skin on the frame of the formwork element can be achieved, which prevents formwork elements constructed in this way from getting caught when they are used for transport or for Storage to be stacked. In this way, damage to the stacked formwork elements can be avoided. Furthermore, it can be useful for the formwork skin to protrude over the
- Struts of the respective formwork element should also rest 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. This can create a rectangular
- Formwork element result. Especially with rectangular
- Formwork elements can strut along a short side of a rectangular basic shape of the frame
