    The invention relates to a formable hardening material, in particular concrete, for the production of a staircase, with a supporting structure which has a shuttering wall for the underside of the staircase and mutually adjustable formwork elements for the formation of steps.
    Due to the different storey heights and ceiling thicknesses in construction as well as different appearance widths,
    Auflägerausbildüngen and Laufplattenstärken the stairs themselves, there is a need for many different formwork for stairs. This reduces the economic benefit that prefabrication has over the stairs made on site.
    Therefore, in the field of manufacturing precast concrete products, there are also staircase formwork systems in which the main dimensions (gradient ratio, platform thickness, platform width) can be set in certain orders of magnitude. Often, however, additional individual formworks made of wood must be made to supplement the systems.
    For large quantities, the share of shuttering costs in the total production costs is rather low. Often, however, many stairs with different dimensions are required. Large quantities of stairs of the same dimensions are usually needed only over a long period of time. The manufacturer then has the choice, either to produce on request and so each time to bear the cost of changing the formwork or the purchase of many formwork or to produce in stock, " which causes high storage costs.
    Due to the usually small number of individual stair types (even with large total orders) and the often short-term and intermittent need for different types of staircase creates a high formwork effort and deadline pressure.
    The object of the invention is therefore to provide a formwork system available, which reduces the above problems.
    This object is achieved by a formwork of the type mentioned above with the characterizing features of claim 1. 2/21: • · · * · * ······
    An inventive device largely satisfies the above-mentioned drawbacks. The formwork system preferably consists of a stationary anchored to the ground support structure on the side of the steps and a demountable mounted on the ground support structure on the side of the Laufplattenuntersicht.
    The two support structures form the formwork body.
    The individual steps are formed by formwork elements that can be adjustably screwed in relation to the step depth. The individual shuttering elements for the steps are in the course of shuttering setting on prefabricated support plates, which were positioned on the stationary support structure part of the formwork and define together with the formwork elements the geometry of the stairs, applied and then attached.
    To achieve a gradeability of the step height to a small extent, the individual formwork elements of the steps can be installed inclined. The required inclination to reach the desired step height can be defined by the geometry of the prefabricated support plates on which the formwork elements for the steps are arranged and / or by the formwork parts of the upper landing plate.
    Due to this design principle, it is possible to form different step heights with only one step formwork in a restricted area. As a result, all common pitch ratios can be covered with just a few types of step formwork.
    The width of the staircase can be set or achieved by inserting a shuttering on the ground or by filling it with less concrete. For the formation of the upper and lower stairwell formwork parts are mounted within the formwork, which are designed so that the required geometry of the stairs is formed.
    The same design principle is also used for podium formations. 3/21 • · ······························································································· · Fa
    Thanks to this technology, it is possible to carry out particularly cost-effective and space-saving formwork foundation constructions. • execute any formwork settings very quickly and cost-effectively; • create a staircase in every formwork even when setting a new staircase geometry; • to offer very short delivery times even with different staircase geometries; • as needed " Just in Time " to produce and place the stairs directly after production (without intermediate storage) in transport containers.
    Further preferred embodiments of the invention are the subject of
    Dependent claims.
    Further features and advantages of the invention will become apparent from the following description of a preferred embodiment of the invention with reference to the accompanying drawings. It shows:

    Figures 1 to 4 show a first embodiment of the invention. 1 shows a perspective view of a single formwork element 1 according to the invention. Several formwork elements 1 can be joined together, as shown in FIG. The formwork elements 1 form the formwork for the top or the steps of a staircase.

    Support structure 2, a formwork wall 3 and other elements form a complete formwork 4 for a staircase, although terminations 28, 29 (Fig. 4), which limit the formwork at the sides facing the stair ends, are shown only halfway.
    Fig. Lb is only for orientation in the designation of the individual elements of a staircase. A first arrow a shows the appearance width or depth of the stairs. A second arrow b shows the staircase width. A third arrow c shows the step height. A fourth arrow d shows the length of the stairs. The terms length, height, width and depth are used in the following for the formwork and the staircase made thereof in the same way and describe the same directions.
    The formwork element 1 shown in Fig. 1 has four particularly important for the invention walls 5, 6, 7, 8. These include the two formwork walls 5, 6, through which the steps of the stairs are defined when using the formwork 4. Furthermore, the formwork element 1 on a connecting wall 7, in which, for example, two slots 9 are. About these slots 9, the connecting wall 7 can be adjustably connected to the shuttering wall 5 of an adjacent shuttering element. But this is not mandatory. For this purpose, the formwork elements 1 have two projections, in particular screws 11, which engage through the slots 9 of an adjacent formwork element 1. By moving the shuttering elements 1, the depth of a staircase or step width of the steps formed by the formwork 4 stairs can be adjusted and then firmly connected by tightening the screws.
    To counterbalance the connected formwork elements 1 and counteract bending by pressure generated by material loaded into the formwork such as concrete, support plates 12 (Figure 2) are provided which are sawtooth in this embodiment. These have projections 10 (FIG. 2) which engage in corners 13 of the formwork elements 1. The corner 13 is in each case formed by further walls 15, 16 of the formwork element 1. Embodiments in which, for example, only one wall instead of 5/21
    two walls is provided, 3iiid »* au« n. »& The support plates 12 could in this case, for example, engage in a groove or lie flat. However, a substantially L-shaped profile of the formwork elements 1 is particularly advantageous for the stability of the structure.
    The sawtooth-shaped support plates 12 are made new for each type of staircase, so they are preferably made of a cheap and easy to edit material, such as MDF boards or wood. If they are not needed, they can be stored in a very space-saving way.
    Fig. 3 shows the formwork 4 with the invention assembled and used formwork elements 1. The preferably attached to the ground, step-side support members 17 of the support structure 2, which has a first support wall 18, while keeping in this embodiment optionally interconnected formwork elements 1 vertically in the correct location. The wall sections 8 of the formwork elements 1 are preferably aligned approximately parallel to the support wall 18. Thus, the formwork elements 1 can be easily connected to the support wall 18 via clamping elements 19. The clamping elements 19 are screws in the illustrated embodiment. These screws 19 engage in the illustrated embodiment on the formwork elements 1 in holes 21 (FIG. 1) and on the support wall 18 in a slot 22 a. The displaceability of the screws 19 in the slot 22 thereby ensures the stepless adjustability of the formwork elements 1. Embodiments in which the support wall 18 instead of the slot 22, for example, a series of holes, in particular slots has, are also conceivable. After installation of the formwork elements 1, the screws are tightened and clamped the formwork elements 1 on the support plates 12 with the support wall 18.
    The sawtooth-shaped support plates 12 are held in der.dargestellt embodiment by paired L-profiles 23, which form guide rails for the sawtooth-shaped support plates 12 in the illustrated embodiment. Embodiments in which the sawtooth-shaped support plates 12 are held in a different manner, for example by U-profiles, are also conceivable. 6/21 Λ ··· · · · · # ·· »β * ·« «· g · • ο η%« 6 · e θ g · φ ···· § ·· ο g * · * «« · · · ^
    The underside of the wall is formed. This is preferably composed of two parts 24, 25, which are pivotally connected via a hinge 26. Thus, the upper end of the stairs can be made in one piece with the steps. The joint can either be performed so that it is sealed against filled concrete, or sealed separately for each staircase, for example by silicone or neoprene.
    The formwork wall 3 is reinforced by reinforcing profiles 27, in the illustrated embodiment H-profiles. With sufficiently strong design of shuttering wall 3 but can be dispensed with such a gain.
    4 shows a perspective view of the formwork according to FIG. 3 from above. It can be seen two closing formwork 28, 29. By this upper or lower end of the stairs is formed, which then connects to the ceiling panels or podiums, which are connected by the stairs. This formwork shutters 28, 29 are made separately for each type of staircase and may for example consist of wood or a wood material, such as MDF. But there are also all other types of cheap and easy to cut materials.
    Fig. 5 shows a perspective view of a second preferred embodiment of the invention. The support wall 18 is shown only partially for clarity. The
    Shuttering elements have, as in the first embodiment, two shuttering walls 5, 6. The task of the connecting wall 7 is taken over in the second embodiment by a connecting edge 31 of the shuttering wall 6. This comes to lie in the assembled state on the formwork wall 5 of an adjacent formwork elements. The connecting edge 31 may additionally have sealing means (not shown), for example made of neoprene, in order to prevent concrete from escaping. With clamping elements 19, the formwork elements 1 are again stretched against the support wall 18. Instead of the sawtooth-shaped projections 10, the support member 12 in this embodiment depressions 32. In the recesses 32 are longitudinal edges of the shuttering wall 5 and the adjoining positioning walls 34, 35, 36. In this case, the arrangement of the recesses 32 in the support member 12 determines the staircase geometry, similar to 7/21 ······· ··· In the first execution !: brm * is defined by the projections 10. The support member 12 is shown in the second embodiment, only by way of example, it can be provided both a plurality of support elements and support elements with differently shaped depressions. It is advantageous in the second embodiment over the first embodiment that the cost of materials for creating the respectively adapted to a staircase support elements 12 can be kept smaller.
    6 shows a third alternative embodiment of a formwork element according to the invention 1. The formwork element 1 has, analogous to the embodiments described above, two formwork walls 5, 6, whose position defines the subsequent geometry of the stairs to the formwork walls of adjacent formwork elements. The height of the stairs (Fig. Lb, arrow c) was in the previous embodiments only by an inclination of the formwork elements (slightly) adjustable. The embodiment shown in FIG. 6 has a first mounting strip 38 on the shuttering wall 6 for improved adjustability of the height of the staircase formworks. An extension element 40 with a second mounting strip 39 can be attached to the first mounting strip 38 on the formwork element 1. An extension wall 41 of the extension element 40 is thereby added, preferably as seamless as possible, to the shuttering wall 6 and forms with this preferably a plane. By means of extension elements 40 with different height extension walls 41, the height of the steps can be adjusted as desired in a staircase made with a formwork according to the invention. The extension elements 40 can be stored in a particularly space-saving manner. The two mounting strips 38, 39 can be connected, for example via screws 37.
    7 shows a perspective side view of an embodiment of a formwork 4 according to the invention. Between the formwork elements 1 and the shuttering wall 3, a shuttering 42 is arranged at an adjustable height. This has essentially the shape of one side of the stairs and is supported against the ground. By choosing the height of the shuttering 42, the width of the stairs can be defined. 8.21
