Definitions

  • the invention relates to a component for the shell concrete construction, consisting of two mutually parallel shell parts with plug-in form-locking means on their narrow sides and at least one plug-in web connecting the two shell parts to one another, which engages with its T-shaped end flanges in vertical grooves of the shell parts.
  • Components of this type are known, which are assembled by plugging their individual parts together at the construction site and then assembled to form a floor-to-ceiling wall, which in turn is then filled with concrete.
  • Such components also have metal webs, which consist for example of relatively thin steel sheets and have laterally bent flanges which engage in the inner T-grooves of the casing parts.
  • These inherently stable webs prove to be unbreakable when filling the filling concrete, but because of their low overall weight they do not allow a composite wall, including the action of the form-locking means of the casing parts of the components, to be stiff enough to withstand the wind forces or otherwise before backfilling to withstand effective transverse forces with concrete.
  • a stronger and larger dimensioning of the metal bars would lead to very high manufacturing costs for the bars.
  • a further disadvantage of such webs is that they conduct heat very well, so that in the event of a fire, there is a risk that the heat at the locations of the webs is quickly conducted through the concrete wall and on the other side of the wall to spread the fire leads. The fire protection is therefore not given. Furthermore, there is a further disadvantage that there is a risk of floating individual components when filling with concrete.
  • the object of the invention is to improve a component of the type mentioned at least in such a way that with such elements storey-high and ready-to-fill walls have a sufficient transverse rigidity and, after the filling and setting of the concrete, provide protection against the spread of fire and that the elements secured against floating when filling the concrete.
  • the solution to the problem is based on the component mentioned and is characterized in that the web consists of synthetic concrete, such as polyester concrete, fiber-reinforced concrete, asbestos cement or the like material.
  • Such a component ensures a storey-high casing wall structure which has sufficient transverse rigidity before and during the filling with concrete, so that wind forces in particular do not lead to a transverse displacement of components of a casing formwork ready for filling.
  • the floating of the elements when filling the concrete is practically avoided.
  • the general structure of the component shown in FIG. 1 is characterized by the two jacket parts 1 and 2 and by the webs 3 which connect the two jacket parts to one another.
  • the jacket parts have T-grooves 4 which are open on the inside and into which the end flanges 5 and an edge region of the bridge part 6 of the webs 3 adjoining these flanges engage.
  • the material for the webs 3 consists of synthetic concrete, for example polyester concrete or fiber-reinforced concrete. Also suitable is asbestos cement or other material which has a low heat conduction coefficient and whose melting point is at least as high as that of the concrete which is filled into the component in question. Furthermore, the suitable web material should also be fire-proof.
  • the webs 3 are shaped such that their bridge part 6 has a thickened central part 7 extending in the vertical direction, the height of which is equal to the height of the jacket parts 1 and 2. Otherwise, the bridge parts 6 are plate-shaped, as clearly shown in FIG. 2.
  • the regions 7 have a pin 8 at one end and a complementary hole 9 at their other end. If two components are plugged onto one another, the pins 8 of one element engage in the holes 9 of the other element.
  • the bridge part 6 of the webs 3 also has a vertical through-channel 10 which, in a further embodiment of the component, runs centrally through the thickened region 7, namely from the pin 8, which preferably has a square cross-section, to the complementary hole 9.
  • the diameter of the through-channel 10 is selected so that a reinforcing bar (not shown), which is usually inserted through the channels, rests frictionally against the inner wall of the through-channels. Because the diameters of such reinforcing bars or reinforcing bars are standardized, it is not difficult to select an appropriate friction fit for the through-channel 1D. Such a design of the through-channel additionally counteracts the floating of the component.
  • the bridge part 6 extends, except in its thicker central region 7, only partially over the entire height of the web 3, so that the concrete filled into the component also has a cross connection with one another in the set state in the usual way.
  • the diametrically opposite flanges 5 of each web 3 are designed as relatively wide plates ( Figure 2).
  • the width of the plates is preferably chosen so that it is about one third to three quarters of their spacing apart. This ensures that the plates or flanges 5 with a corresponding fit of the T-slots in the jacket parts 1 and 2 have a relatively tight fit in the jacket parts, which further the rigidity of a put wall improved.
  • the relatively wide plates or flanges in the case of jacket parts made of rigid foam greatly reduce the risk of the jacket parts breaking out in the region of the flanges 5.
  • the flanges 5 are provided with the grooves 11 at the bottom and with the springs 12 at the top.
  • the material for the casing parts 1 and 2 can consist of the commonly used rigid plastic material, for example polystyrene.
  • the component it is also possible to proceed in a further embodiment of the component so that at least one of the shell parts 1, 2 consists of plaster material.
  • a material will be used if the corresponding wall surface faces the interior of a building.
  • Such a wall surface has the advantage that it does not have to be provided with the usual wall plaster. Overall, it is so smooth and level that you can start painting immediately. Masonry work can therefore be omitted.
  • the webs 3 described above can advantageously be used, the parts 5 of which engage on the jacket parts can also have configurations other than the plate shape shown, which then encompass corresponding configurations of the jacket parts.
