Definitions

  • the invention relates to a steel-concrete ceiling, in particular a steel-concrete ribbed ceiling or a steel-concrete composite ceiling, with at least one ceiling support, are supported on the transverse trapezoidal sheet metal, which are filled with concrete on the upper side, wherein the trapezoidal profile sheets with the End portions of their troughs are superimposed on bearing parts, which are mounted offset from the top of the ceiling support at this and projecting console side of the ceiling support.
  • a steel-concrete ribbed ceiling or composite ceiling usually has several parallel ceiling beams made of steel or concrete.
  • profiled steel sheets in particular in the form of trapezoidal profiled sheets, were placed on the ceiling beams transversely to their longitudinal extension and fastened on the upper side of the ceiling beams.
  • the ceiling support is made of steel, several head bolt dowels are additionally attached on its upper side, which serve for thrust transmission.
  • the trapezoidal profiled sheets are filled with Ortbetow far enough that the entire trapezoidal sheet metal is sufficiently covered with concrete, i. the troughs of the profile are completely filled and also the wave crests are covered with a sufficient layer of concrete.
  • the height of the trapezoidal sheet metal to be covered by the concrete is very large for large spans, whereby the ceilings are very heavy and have a relatively large height.
  • a disadvantage of this construction is that the open end faces of the trapezoidal profile sheets, in particular in the region of the troughs, must be sealed by means of special sealing bodies in order to prevent the liquid concrete from leaking to the side until it has hardened. This additional lateral sealing of the trapezoidal sheet is laborious and time consuming and thus costly.
  • the invention has for its object to provide a steel-concrete ribbed or composite ceiling of the type mentioned, in which, while maintaining the above advantages with a structurally simple design an end-face seal between the troughs of the trapezoidal profile sheet and the bracket-like bearing parts is given.
  • each bearing part has a receiving space having a substantially U-shaped, upwardly open cross-section, comprising a bottom portion and two side walls, and that the trapezoidal profile sheet with its trough inserted into contact with the side walls and the bottom portion in the receiving space is, wherein the concrete is within the receiving space of the bearing part in direct contact with the side walls of the web of the ceiling support, so that the ceiling support is laterally stabilized.
  • the invention is based on the basic idea not only to provide the console-like support parts with a flat support surface, but to provide a trough-like or trough-like receiving space, in which the trapezoidal profile sheet is used with its wave trough.
  • the trapezoidal profile sheet attaches to the underside of its wave trough the bottom portion of the receiving space and with the side walls of the wave trough on the side walls of the receiving space, whereby between the wave trough and the bearing part a sufficient at least for concrete sealing is achieved.
  • the bearing part is preferably mounted on its side facing away from the trapezoidal sheet metal sheet in a sealed manner to the ceiling support and in particular welded, so that the liquid concrete, which is filled on the top of the trapezoidal sheet in its troughs, at the front ends of the troughs in the receiving space of the respective Warehouse parts occurs, but can not escape from this.
  • the inner contour of the bearing part is complementary to the outer contour of the wave trough of the trapezoidal profile sheet.
  • the height of the cross section of the receiving space corresponds to the height of the trapezoidal profile sheet.
  • the trough of the trapezoidal profile sheet can be completely accommodated in the receiving space of the bearing part, whereby a complete lateral sealing of the troughs is ensured.
  • the upper edges of the troughs are in the region of the upper belt of the ceiling support.
  • a plurality of bearing parts are arranged in the longitudinal direction of the ceiling support at a mutual distance one behind the other.
  • the distance between two adjacent bearing parts may correspond to the spacing of adjacent troughs of the trapezoidal profile sheet, so that each corrugation trough is received and held in a bearing part.
  • the distance between two adjacent bearing parts corresponds to an integer multiple, for example twice the distance between adjacent troughs of the trapezoidal sheet metal, so that only every second, third or fourth trough of the trapezoidal sheet is received in a bearing part.
  • the ceiling support is a steel beam with an I-profile, wherein the bearing parts, which are also made of steel, are laterally welded to the web of the ceiling support preferably circumferentially.
  • the top of the trapezoidal profile sheet is at the level of the top of the ceiling support and in particular steplessly and / or gap-free merges into the top of the ceiling support. It can be provided that the wave peaks of the trapezoidal sheet with its end faces abuts the lateral edge of the upper belt of the ceiling support, whereby a seal between the wave crest and the ceiling support is achieved.
  • reinforcement steel in the form of so-called upper and lower longitudinal and transverse reinforcement is introduced in a conventional manner, before the concrete is filled.
  • the invention may be provided that in the ceiling support in the area within the receiving space of the bearing part, a through hole is formed through which at least one reinforcement member and in particular a rod-shaped reinforcing steel can be passed.
  • FIGS. 1 to 4 a partial construction of a steel-concrete ceiling 10 has a plurality of parallel ceiling support 11, of which only one is shown.
  • the ceiling support 11 is made of steel and has an I-profile with a lower flange 13, a top flange 14 and a vertical web 12.
  • each laterally projecting steel bearing members 15 are mounted, which protrude laterally like a bracket transverse to the longitudinal extent of the ceiling support 11.
  • Each bearing member 15 is bent from sheet steel and has a trough-like shape with a trapezoidal, substantially U-shaped, upwardly open cross-section with a bottom portion 15a and two side walls 15b.
  • the bearing part 15 is open at its ends.
  • the bearing part 15 For attachment of the bearing part 15, this is placed with an open end face on the side surface of the web 12 of the ceiling support 11 and welded to a weld 17, the upper edges of the side walls 15b of the bearing part 15 abut or close to the underside of the upper belt 14 of the ceiling support 11 are arranged at this.
  • the mounted on the ceiling support 11 bearing member 15 forms between its side walls 15b and above the bottom portion 15a a receiving space 16 which is open on its upper side and on the ceiling support 11 facing away from the end of the bearing part 15.
  • a trapezoidal profile sheet 18 has in cross section in the usual way a plurality of spaced apart wave troughs 18a, which are each connected to one another via a so-called wave crest 18b.
  • the troughs 18a also have a substantially U-shaped cross-section.
  • the cross-section of its corrugation 18a of the trapezoidal sheet 18 and the cross-section of the bearing part 15 and the receiving space 16 are coordinated so that the inner contour of the receiving space 16 of the bearing part 15 is complementary to the outer contour of the corrugation 18a of the trapezoidal sheet 18.
  • Trapezoidal sheet 18 with its troughs 18a in each case a receiving space 16 of a bearing part 15 can be used and in the inserted state both on the bottom portion 15a of the bearing part 15 rests as well as over the entire surface on the inside of the side walls 15b.
  • a plurality of bearing parts 15 are arranged at a mutual distance one behind the other, wherein the distance between two adjacent bearing parts 15 corresponds to the distance between adjacent wave troughs 18 a of the trapezoidal profile sheet 18.
  • the height of the receiving space 16 corresponds to the height of the trapezoidal profile sheet 18, so that the wave trough 18a of the trapezoidal profile sheet 18 can be completely accommodated in the receiving space 16 of the bearing part 15.
  • FIG. 3 shows the trapezoidal profile sheet 18, which is used with its wave troughs 18a in each case a receiving space 16 of a bearing part 15 with its end portion E.
  • the bearing parts 15 are arranged so that the top of the trapezoidal profile sheet 18, ie its so-called wave peaks 18b, which have a substantially horizontally extending top surface, lie at the level of the side edge of the upper belt 14 of the ceiling support 12 and abut against it.
  • the upper side of the trapezoidal profile sheet 18 passes smoothly and / or without gaps into the upper side of the upper belt 14 of the ceiling support 11.
  • FIG. 4 is a lower longitudinal reinforcement 21, which extends within the wave troughs 18a of the trapezoidal profile sheet 18, an upper longitudinal reinforcement 20, which extends above the trapezoidal profile sheet 18 and in particular passed over the longitudinal beam 11, and an upper transverse reinforcement 22 is shown.
  • the longitudinal member 11 is provided on the upper side of its upper flange 14 with spaced head bolt dowels 19, which serve the thrust transmission.
  • the concrete 23 is introduced, which is heaped up over the upper edge of the arranged on the longitudinal beam 11 head bolt dowel 19 and smoothed in the usual way.
  • the concrete 23 is within the receiving space 16 of the bearing part 15 in direct contact with the side walls of the web 12 of the ceiling support 11, whereby the ceiling support 11 is additionally stabilized laterally.
  • the upper longitudinal reinforcement 20 is guided away in the illustrated embodiment as a continuous reinforcement on the ceiling support 11. This limits the formation of cracks in the concrete 23.
  • the lower longitudinal reinforcement may be at least partially formed as a continuous reinforcement by penetrating the ceiling support 11. This is according to FIG. 5 provided in the web 12 of the ceiling support 11 in the area within the receiving space 16 of the bearing part 15, a through hole 24 is formed, through which the lower longitudinal reinforcement 11 can be passed.
