Definitions

  • FR-PS 23 56 783 it is known from FR-PS 23 56 783 to provide the edge of the ceiling panel with metal support profiles, which have an inner anchoring section in the finished part are anchored and rest with a projecting support portion on the L astsuitvoriques where then carried out in a suitable manner a casting with in-situ concrete.
  • Each girder profile consists of four closed, vertical stiffening walls in the installed position, which are extended in the concrete by lower anchor brackets, which have a bent lower edge for effective anchoring in the concrete.
  • the invention has for its object to provide a prefabricated reinforced concrete part of the type outlined in the preamble of claim 1 and a support profile therefor in such a way that without a welded connection between Beam profile and reinforcing steel a structurally safe introduction of the anchoring forces of the beam profile into the reinforcement can take place.
  • the load distribution device receiving distance between the bottom wall of the support profile and the support section of the head part is kept variable, so as to be able to make height adjustments of the support profile in the reinforced concrete part if necessary. This is possible without further ado, since there must be a considerable distance between the support section and the bottom wall in order to avoid local crushing of the concrete and to ensure sufficient load distribution. However, it is not critical to increase this distance from a minimum that ensures this, if necessary, so that here there is a degree of freedom for adaptation measures and, for example, dimensional inaccuracies of the reinforcement cage can also be compensated for.
  • the load distribution device also comprises reinforcing bars which run at least approximately parallel to the bottom wall of the support profile and which, for example, rest on the one hand on the top of the bottom wall and on the other hand on the arcuate support section of the head part of the reinforcing steels. Since the reinforcement bars are in turn softly supported in the concrete cushion against the contact pressure, there are no harmful stress peaks when concrete material is pushed between the reinforcement bars and their contact surfaces on the bottom wall or on the support section. On the other hand, the reinforcing bars support the load distribution in the concrete cushion due to their rigidity.
  • a particularly rigid construction of the support profile results when it is designed as a box profile with a horizontal central axis according to claim 5:
  • the reinforcing steels can have through openings according to claim 6 reach through in the bottom wall so that their headboards lie in the interior of the box section.
  • a convenient and perfect complete filling of the interior of the box section with concrete and its control is possible in that filling openings are provided in the lateral stiffening walls and / or the ceiling wall according to claim 7: D such filling openings can also be used for further storage of the support profile such as transverse arranged reinforcing bars that pass through the filler openings.
  • BE-PS 774 213 From BE-PS 774 213 it is known to have a support profile overlapped by curved head parts of the reinforcing steels and thus to hold them.
  • the support profile there which also has no floor or ceiling wall, is overlapped by the correspondingly bent head parts of the reinforcing steels without clearance, so that the head parts still have to be welded to the support profile in advance to avoid uncontrolled surface pressures, and this effort cannot therefore be dispensed with.
  • the prefabricated steel - concrete part of BE-PS 774 213 is a prefabricated part with a solid concrete support and the resulting disadvantages which have already been explained above and are known.
  • a support profile 10 consists of an anchoring section 12 that can be concreted into a prefabricated reinforced concrete part with reinforcing steels and a free, protruding support section 14 that serves as a support for the prefabricated reinforced concrete part on a corresponding load-bearing device 44 (see FIG. 2).
  • the carrier profile 10 is a rectilinearly elongated box profile with a central axis lying horizontally in the installed position and with a uniform outside width B AP , an inside width B IP and a clear inside height H IP .
  • inner ribs 16 for stiffening are arranged, which run over the entire width B ip .
  • the underside 20 of the carrier profile 10 is formed on a bottom wall 28, which is connected to an upper ceiling wall 30 via two lateral and upright stiffening walls 24 in the installed position. Inspection and filling openings 32 of different diameters are arranged in the ceiling wall 30 both in the anchoring section 12 and in the support section 14, through which the concrete to be poured into the support profile 10 can flow and, in particular, can also be checked and compacted, so that no dangerous cavities can carry the load endanger the connection with the iron and steel. Likewise, filler openings 34 are provided in the lateral stiffening walls 24 so that a full pouring of the entire support profile 10 is possible.
  • a 'filling opening 34 is provided in the region of the transition line 36 from the anchoring section 12 to the support section 14, so that a seamless connection to the concrete of the reinforced concrete part in Area of the anchoring section 12 can be ensured.
  • FIG. 2 Representation of a reinforced concrete part shown in the form of a ceiling slab, which very clearly shows the composite according to the invention between the support profile 10 and the reinforcement of the reinforced concrete part ' .
  • the carrier profile 10 according to FIG. 1 essentially corresponds to that according to FIG. 2, the same reference numerals have been used for the same parts, so that a further explanation of these parts is unnecessary.
  • the space enclosed by the lateral bracing walls 24, the bottom wall 28 and the ceiling wall 30 of interior 42 of the square profile is filled in the region of the anchoring portion 1 with 2 precast concrete, while exposed in the region of the support portion 14 of precast concrete.
  • the Support section 14, which has not yet been filled with in-situ concrete in the illustration according to FIG. 2 rests on the load-bearing device 44, such as a support of a girder, an insulating plate 46 made of plastic such as neoprene or rubber being used in between for sound insulation and at the same time a plain bearing for longitudinal expansion of the entire precast reinforced concrete part.
  • the load suspension device 44 in the illustration according to FIG. 2 is matched to the precast reinforced concrete part in accordance with practice in such a way that, for example, a flat ceiling of the space underneath would result.
  • reinforcing bars 40 are additionally provided on the upper side of the bottom wall 28 and reinforcing bars 38 are additionally provided on the underside of the support section 58, which are arranged parallel to the bottom wall 28 and further improve the effect of the load distribution device 50.
  • the reinforcing bars 38 and 40 can extend on the one hand beyond the inner end of the anchoring section 12 into the precast concrete part, and on the other hand also extend beyond the other end of the anchoring section 12 into the supporting section 14 and thus ensure an intimate connection with the in-situ concrete to be introduced later.
  • a box profile is particularly advantageous with regard to the fact that it can absorb high bending moments with a relatively small dimension and, moreover, is particularly well suited, for example, in the manner illustrated by way of example for a weld-free anchoring of the type described, which requires little assembly effort.
  • the box profile itself can be constructed in the manner shown in FIG. 3 from two L profiles welded together, one L profile being a lateral stiffening wall 24 and the top wall 30 and the other L profile being the other stiffening wall 24 and the bottom wall 28 includes.
