Definitions

  • the invention relates to a prefabricated reinforced concrete component with a longitudinal extension, with end-side support elements, the support element consisting of a steel profile which is arranged on the top of the prefabricated reinforced concrete component, which projects with part of its length over the end of the prefabricated reinforced concrete component and rests with a flange on a supporting structure and is held in the prefabricated reinforced concrete component by concreted-in anchoring elements.
  • Precast reinforced concrete components to which the invention is applied finds can for example be designed as a bar or slab beam or also have the shape of a PI plate, or also the shape of a web profile.
  • Reinforced concrete components with a longitudinal extension are known which are supported on supporting components, either on brackets or on supporting structures such as beams, beams or the like.
  • supporting components either on brackets or on supporting structures such as beams, beams or the like.
  • FR-OS 2 283 269 describes a prefabricated reinforced concrete component of the type specified at the outset.
  • a steel profile in the form of a T-profile is placed on the end of the precast reinforced concrete component, in such a way that the web of the T stands up and the flange of the T forms a bearing surface for the precast reinforced concrete component on a supporting structure. This contact surface projects beyond the end of the web profile.
  • the T-profile is provided with anchoring elements, which in turn are partly connected to the reinforcement of the web profile.
  • the above steel profile means that the support structure is loaded more in the central plane. Finally, the steel profile is covered with in-situ concrete and a uniform surface is obtained.
  • the known prefabricated reinforced concrete component is comparatively complex to manufacture and also only slightly resilient.
  • the invention is based on the precast reinforced concrete component of the type specified at the outset.
  • the steel profile be formed with a lower flange and an upper flange, the upper flange protruding upward from the prefabricated concrete component.
  • the use of a steel profile with a lower flange and an upper flange allows the transmission of high forces and moments with economical dimensions.
  • a component of this design is able to cope with both the transverse forces that occur and the bending moments that occur, without it being necessary to use oversized cross sections.
  • a particular advantage of the invention is that laying with a hoist is not difficult. This is because the hoist can be attached to the upper chord projecting upwards. During transport, there are no loads other than those that also occur in the assembled state, so that additional reinforcements are unnecessary.
  • the selected arrangement has the further advantage that incorrect handling during transport or during installation is avoided. Transport forces can only act on the upper flange of the steel profile at the concrete part ends. This avoids negative moments.
  • the stacking of the prefabricated concrete components facilitates or enables.
  • the reinforcement of the precast concrete element often protrudes upwards in order to obtain a secure connection with the in-situ concrete that will be applied later.
  • the steel profile used according to the invention offers exact support points for the prefabricated concrete components, for example with the interposition of beams or similar means. This in turn ensures that the precast reinforced concrete components are only supported in the end areas and that no additional forces or negative moments occur during intermediate storage, which the precast reinforced concrete component might not be able to withstand.
  • the lower flange of the steel profile carries a support plate with which the steel profile rests on the support structure.
  • the invention achieves that the load-bearing forces are introduced into the support structure at a predetermined point and that an overloading of the edge regions of the support structure, which could result in edge chipping, is avoided. Measures which are otherwise customary and which are intended to preclude the breaking out of overloaded edge parts are therefore not necessary.
  • a double-T profile can be used in the invention. It is also possible to use a rectangular tube, for example made from two U-profiles. In this case, the hoist engages in the steel profile from the ends.
  • the steel profile can be placed on the web profile. However, it is better if the steel profile over a part its height is concreted into the web profile.
  • the invention proposes in particular an anchoring element which is essentially formed by a rod which projects at right angles from the steel profile and which has an end anchorage, for example a plate or a hook, at its lower end.
  • end anchors such as upsetting, spreading or the like, are also possible.
  • the reinforcement at the end of the web profile thus has a very simple shape that can be produced with little effort. Even inserting it into the precast concrete part presents no problems.
  • the plate at the end of the bar which is preferably equipped with anchoring ribs, provides a secure hold in the prefabricated concrete component. As a rule, it is possible to dispense with additional connections with the reinforcement of the prefabricated concrete component.
  • the screw connection consists of a screw sleeve with an internal thread into which the anchoring rod can be screwed.
  • a construction of this type has the advantage that the length of the anchoring rod can be adapted to the respective needs. The same construction can therefore be used for different construction heights of the precast reinforced concrete element. A longer or shorter anchor rod is used in each case.
  • Another advantage is that the provision, storage and transport of these parts is possible with a small amount of space.
  • 1 and 2 essentially comprises a web profile 1, consisting essentially of a plate 10 with one or more webs 11.
  • the plate 10 and the webs 11 have horizontally and vertically extending reinforcements 12 and 13.
  • the vertical extending reinforcements 13 protrude with their upper ends 14 from the plate 10.
  • a steel profile 2 is partially embedded in the plate 10, which in the exemplary embodiment shown is designed as a double-T profile and comprises an upper flange 20 and a lower flange 21, which are connected to one another by means of the web 22.
  • the steel profile 2 protrudes beyond the end 15 of the web profile 1.
  • a support plate 25 is welded to the underside of the projecting part 24, with which the web profile 1 stands on a support structure 3.
  • an in-situ concrete 30 is applied which covers the upper ends 14 of the reinforcements 13 and possibly also other horizontal reinforcing bars 16 covers.
  • these serve to take over the share of the traffic load.
  • the load components from the dead weight of the prefabricated reinforced concrete component and the in-situ concrete layer, which already arise during assembly and installation, are transferred from the steel profile to the support structure.
  • the load components from the later traffic loads are borne by additional reinforcements in the in-situ concrete area and the reinforcements 12, 13, 14 and 16. This interaction of the reinforcement and the steel profile enables a particularly economical dimensioning that was previously unknown.
  • a sleeve 26 with an internal thread 27 is welded onto the underside of the lower flange 21 of the steel profile 2.
  • the rod 28, which carries an anchoring plate 29 at its lower end, can be screwed into this sleeve 26. In this way, it is easily possible to combine rods 28 of different lengths with a steel profile 2, so that adaptation to different heights of the webs 11 is possible in each case.
  • a steel profile 2 is assigned to each of the webs 11.
  • the platen 25 is comparatively low. In many cases, however, it is advisable to use a support plate 25 at a sufficient height of, for example, 25 millimeters, and to design the prefabricated reinforced concrete component in such a way that a concrete cover is obtained on the underside of the steel profile 2 projecting beyond the end 15, which eliminates the risk of corrosion .
