Definitions

  • the invention relates to a roof or ceiling slab, designed as a concrete-steel composite construction, with steel beams, on which are provided in the transverse direction, provided for loading with concrete trapezoidal sheet metal.
  • the present invention has the object to provide a designed as a concrete-steel composite construction roof or ceiling plate, which allows the use of a low-cost standard reinforcement.
  • the solution according to the invention means that the extension profiles or troughs are guided over the extension profiles up to the vertical web of the steel beams, so that the extension profiles abut with their end face on the web of the steel support at least approximately , In this way, a continuous action for the reinforced concrete ribs can be achieved.
  • deliberately no support is created between steel girder and reinforced concrete rib.
  • extension or additional profiles and / or the reinforced concrete ribs produced in the extension profiles are claimed solely to pressure in the direction of their longitudinal axis, so that between the steel beams and the reinforced concrete ribs / extension profiles no frictional connection is formed. It is, as already mentioned, a fürlauf für the roof or ceiling tile, but just not to a support or a wider connection or power transmission. Even lateral forces should not be able to be initiated in these connection points.
  • extension profile rests on the trapezoidal profile sheet on its side facing away from the steel beam in the assembled state over about 30% to 60% of its length.
  • the trained as an extension profile insert is so over part of its length on the trapezoidal sheet metal, but at least approximately with its the trapezoidal profile side facing away from the web of the steel beam and / or lies with its upper edge below the upper flange of the steel support at least approximately. This is one created optimal and above all secure position for serving for extension profile sheet before the trapezoidal sheet is then applied with concrete. In this way, a particularly advantageous continuous action for the roof or ceiling plate can be realized without forming a support.
  • the extension profiles are formed at least approximately the geometry of the wave trough of the trapezoidal sheet metal continued.
  • the formwork element is particularly well suited for generating a continuous action for the reinforced concrete ribbed and just serves only as formwork element and no frictional connection with the steel support has respectively produced no support.
  • trapezoidal profile sheets and the extension profiles are connected to each other via fastening means, for. B. via screw.
  • Another advantage of the invention is that can be used as a device to achieve the continuous action on a standard product in the form of a formwork element. Basically, it is sufficient if the extension profiles have a thickness of about 1 mm.
  • the invention is characterized in particular by the fact that previously calculated only as Einfeldly reinforced concrete ribs calculated in the future as a continuous carrier can be achieved by the reinforced concrete ribs are virtually brought up to the steel beam, so that a corresponding support torque can be absorbed and transmitted. However, it is deliberately neither produced a support nor lateral forces are transmitted. Thanks to the ability to calculate the reinforced concrete ribs in the future as a continuous carrier, crack widths can be performed without the otherwise required stainless steel reinforcement, ie as a significant advantage of the invention can be applied to standard elements such. B. in the form of formwork elements of only about 1 mm thickness for bringing the ribs are used on the steel beam.
  • FIG. 1 In perspective view shows FIG. 1 the production of a roof or ceiling plate 1 with a steel beam 5 and supported on this with concrete trapezoidal sheet 2.
  • the trapezoidal sheet 2 includes at intervals a plurality of troughs 4, 4 ', at their steel beam 5 facing ends 10, 10' extension profiles 3, 3 'are positioned.
  • FIG. 2 illustrates the seat of the extension profile 3, which abuts at its end 11 with its end face 8 practically on the web 9 of the steel section 5.
  • no support is generated and no transverse forces are transmitted. Instead, a load in the direction of the longitudinal axis 6 of the extension profile 3 for generating the continuous action, which is formed in a preferred embodiment as shuttering element 7 takes place.
  • the reinforcement 20, 21, 22 can build much easier compared to the previously known designs, because the crack width detection is massively simplified by the now given recording of the supporting moment and can be resorted to standard reinforcements back. With 18 a head bolt dowel is designated.
  • the steel girder 5 serves to receive the roof or ceiling slab 1.
  • FIG. 3 also in perspective view a roof or ceiling plate 1 during manufacture.
  • the actual trapezoidal profile sheet 2 is deliberately not brought up to the steel beam 5, but remains at a distance from it.
  • the extension, additional or supplementary profile 3 rests on its side facing away from the trapezoidal profiled sheet 2 at least approximately on the web 9 of the steel carrier 5 - and at the same time rests on the trapezoidal profiled sheet 2 on its opposite side 30.
  • the profile 3 corresponds with respect to its shape with the trapezoidal profile sheet 2, ie the contour of the thin sheet 3 corresponds to the inner contour of the trapezoidal profile sheet 2.
  • the extension profile 3 in a broader sense a U-shape formed by two side walls 25 and 26 and the bottom wall 27.
  • the latter has the contour of a W in a broader sense.
  • the profile 3 is at least approximately at the lower edge of the upper flange 15 of the steel beam 5 at.
