    The invention relates to a building with at least one curved construction element made of concrete.
    A building is understood to mean a wide variety of artifacts, which contain at least one curved construction element, but preferably a plurality of them, and the strung together three-dimensional spatial structures, and are relatively difficult to create due to their curvature at the site. These structures include closed spaces with curved roof structures, such as halls for various purposes, warehouses, stations, etc., roofs of open spaces, such as platforms, sports facilities, etc., or sports facilities such as ski jumps, toboggan or bobsled, water slides od. Like., in which also curved construction elements are needed.
    In a building according to the invention, the at least one construction element is characterized by a curved face having lost formwork made of high-strength or higher-grade concrete prefabricated shells that are combined with a Ortbetontragschicht in the composite.
    The problem solved by the invention consists of several small details problems for which more or less useful solutions are already known in detail. For example, for the production of prefabricated concrete parts of especially double-curved structural elements from DE 198 23 610 a lying on a variety of adjustable supports Schaltisch with a bendable and distortable grid known. A similar peeling device for a structural element itself is described in EP 238 168,
    According to the invention according to the three-dimensional shape of the building individual fields of curved construction elements corresponding formwork forms are determined in which then using a high-strength, in particular fiber-reinforced, self-compacting concrete, the individual precast concrete shells are produced for the lost formwork. The precast concrete shells are then, if necessary, arranged according to measures to improve the bonding effect to in-situ concrete on site on existing permanent supports or only temporarily erected scaffolds, sealed together and provided with suitable reinforcements. Reinforcements may be made if the structure is a sports complex, in particular 68369 25 / hn «« * «* * * *« * * * * * · «« * * «« Μ · «· · ·· MI ·· 2
    Toboggan or bobsleigh lane also serve to convey the cooling medium when they are formed as streamable pipes. Of course, it is of course also possible to arrange the tubes for a cooling (or heating medium) in addition to the reinforcement on the composite surface of the precast shells.
    For reasons of weight, the thickness of the concrete layer of the precast shells is as low as possible, for example, between two and ten centimeters, which can be provided as a transport securing reinforcing struts to improve the spatial stability of the precast shells. The stiffening struts are integrated directly into the concrete or subsequently fixed to eyelets, which are introduced into the concrete during manufacture.
    The spent on the site, and arranged on the supports precast pans are then covered with in-situ concrete, the in-situ concrete can be applied in a conventional manner, when the elements are aligned substantially horizontally and, for example, have only small waves with approximately compensating rises and falls.
    However, if the elements at the construction site are more inclined, for example at an angle greater than 30 degrees, there are two possibilities for preventing the in-situ concrete from slipping off before hardening. A first possibility provides here that at least in these inclined areas, the in-situ concrete layer is limited by a second precast shell. These areas are therefore bivalve with a pourable or fillable cavity from which the concrete can not flow until hardened.
    A second possibility envisages that an in-situ concrete wearing course has been sprayed onto the precast shells. This variant is particularly suitable for structures, for example for bobsleigh or toboggan runs, in which the in-situ concrete wearing layer is required mainly vertically on the back of the individual track elements.
    The invention will now be described in more detail with reference to the figures of the accompanying drawing, without being limited thereto. Show it:
    Fig. 1 is a schematic view of a double-curved
    Construction element consisting of several prefabricated shells with
    3 different curvatures in combination with an in-situ concrete layer,
    Fig. 2 Fig., 3 and 4 Fig. 5
    Fig. 6 Fig. 7, 8 and 9 Fig. 10 Fig. 11 Fig. 12 is a schematic view of one of the precast shells of Fig. 1, two embodiments of the edge formation of the precast shells of Figure 1, the arrangement of several precast shells of FIG .. 1 at the construction site to form a permanent formwork for the in-situ concrete layer, a possibility of joint formation in the arrangement of FIG. 5, examples of the bond between the precast shells and in-situ concrete, a variant of the construction element of FIG. 2 with more inclined sections, a view of three prefabricated shells as formwork for a section of a bobsleigh and toboggan run, and a vertical section through an element according to FIG. 11.
    Fig. 1 shows a section of a building with a multiple and alternately curved construction element, in particular with a curved, wavy roof, which rests on supports not shown. The building may, for example, a hall, a sports venue od. Like. Be, in which the free bottom for architectural reasons have a deviating from the flat surface design, and should be curved in all directions, with transitions between convex and concave areas quite well could be.
    The curved construction element has two major components. On the one hand, a layer of prefabricated elements 1, one of which is indicated schematically in Fig. 2, which form a permanent formwork for the structural element, and on the other hand after creation of the lost formwork applied to the site reinforced Ortbetontragschicht 8, with the precast concrete shells 1 enters a network.
    The division of the lost formwork into individual elements 1 allows their prefabrication at a suitable establishment, with the most favorable position or position of the formwork for concreting for each precast shell 1 can be freely determined. The optionally colored high-strength or high-grade concrete for the precast shells 1 is of higher strength than normal concrete and contains in particular metallic or mineral reinforcing fibers, such as steel, glass, etc. (fiber concrete), so that the smallest possible thicknesses (from 2 cm) are executable. The abutment surfaces to the adjacent elements of the lost formwork, as shown in FIGS. 3, 4 and 6 can be formed differently, for example, flat abutting, simply stepped or with tongue and groove, etc. The composite surfaces 2 to in-situ concrete, as FIGS. 7 to 9 show, depending on the size of the forces to be transmitted, also differently formed, for example smooth (FIG. 7), roughened (eg by sandblasting) or serrated (FIG. 8), with protruding anchors 5 or the like (Fig. 9) or by a chemical bonding agent od. Like.
    The sealing of the joints 3 between the individual precast shells 1 can be done by means of inserted sealing strips 4, as shown in FIG. 6.
    To produce the construction element according to FIG. 1, the corresponding prefabricated prefabricated part shells 1 are placed on supports 7, as FIG. 5 shows. Subsequently, the required reinforcement is arranged, which may be flaccid or biased depending on the structure. Subsequently, the application of Ortbetontragschicht 8, in which work or expansion joints can be formed.
    Fig. 10 shows a section of a construction element with a range of greater inclination from about 30 °, in which the in-situ concrete needs a counterhold on the top or outside. This can also be achieved in a simple manner from correspondingly curved prefabricated prefabricated shells 6 at a distance from the precast shells 1.
    Fig. 11 shows a composite of three precast shells 1, lost formwork a portion of a bobsleigh or toboggan run 10, wherein struts and supports 7, the relatively filigree, prefabricated precast shells 1, whose thickness is for example between three and five centimeters, and their curved viewing surfaces After icing the roadway 12 forms, support during transport and installation in the area. At the composite surface 2, which is the outside of the precast shells 1, reinforcements 11 and conduits for a cooling medium are laid, and then the in-situ concrete support layer 8 is sprayed. Fig. 12 additionally shows a final insulation or. Insulation layer.
