Definitions

  • the present invention relates to a cantilever plate connecting element for the insulated, non-positive connection of a floor cover plate with a cantilever plate, with a cuboidal insulation body arranged in the space between the two plates and penetrating them, each to two vertically arranged reinforcement bars, which are surrounded at least in the space by corrosion-resistant sleeves.
  • Such a cantilever plate connection element is known from EP-B-0'338'972.
  • Cantilever plate connection elements have been available on the market in various embodiments for several years.
  • DE-A-31 16 381 described a cantilever plate connection element for the first time, this element, in addition to the tension rods crossing the joint, also having pressure elements in the insulation body, which take over the transmission of the compressive forces.
  • Another embodiment according to EP-A-0'119'165 uses rods shaped in loops instead of straight tension rods, but without additional ones Use shear bars.
  • a tension and a compression rod together form a loop.
  • brackets are attached on both sides of the joint.
  • a cantilever plate connecting element is known from DE-A-34 46 006, in which the rods in the joint area are provided with corrosion-resistant sleeves.
  • the reinforcing bars surrounded with corrosion-resistant sleeves are held in end plates on both sides of the joint.
  • the end plates lie directly in the area of the joint on the cantilever plate or on the floor cover plate.
  • the end plates made of stainless steel have a multiple function. On the one hand, they serve to hold the tension and compression rods and, on the other hand, they counteract the expansion effect between compression and tension rods.
  • the reinforcing bars would be elastically deformed by the alternating load on the cantilever plate in a limited frame.
  • FIG. 1 shows a first embodiment of the cantilever plate connecting element 1 according to the invention in the installed state.
  • the cantilever plate connecting element 1 bridges a joint 2.
  • the joint 2 is located between the cantilever plate 3 and the support side 4.
  • the support side 4 consists of the masonry 5 on which a floor cover plate 6 rests and on which, in turn, a masonry 5 is located.
  • the cantilever plate connecting element 1 thus connects the cantilever plate 3 to the floor cover plate 6.
  • Both the cantilever plate 3 and the floor cover plate 6 are made of concrete.
  • the cantilever plate connecting element consists of several reinforcing bars 11, two of which are arranged vertically one above the other.
  • the upper reinforcing bar 11 is subjected to tension and the lower reinforcing bar 11 to pressure.
  • a plurality of reinforcing bars 11 can be arranged next to one another, as shown for example in FIGS. 3 and 4.
  • the reinforcing bars 11 are encased in their central region with a sleeve 12 made of stainless steel.
  • the reinforcing bars 11 can be made from a commercially available, normal structural steel.
  • the sleeves 12 are longer than in the Cantilever panel connection elements designed according to the prior art.
  • the sleeves 12 can be fitted directly onto the reinforcing bars 11 or surround them spaced apart with the interposition of an injected hardening agent. If the sleeves 12 are pulled onto the reinforcing bars 11, non-ribbed reinforcing bars are used, while in the other case, ribbed bars are preferably used. However, it is entirely possible to use ribbed reinforcing bars 11 on which the sleeves 12 are attached directly.
  • the continuous reinforcement bars and the sleeves 12 penetrate the single end plate 14 as well as the insulation body 10, which comes to rest in the joint 2.
  • the sleeve 12 projects about 10 cm through the end plate 14 on the cantilever plate side.
  • Anchoring elements 15 are attached to the cantilever plate at the upper and lower edge region of the end plate 14.
  • the end plate 14 is a relatively thick flat plate made of stainless steel.
  • the anchoring elements 15 are realized as welded anchoring rods 16, which are also made of stainless steel. Such anchoring rods 16 made of stainless steel are available in a ribbed form with the designation RIPINOX.
  • the anchoring bars 16 can be arranged in the same vertical plane as the reinforcing bars 11, which are in each case arranged in two superposed fashion.
  • An anchoring rod 16 lies above the upper reinforcing rod 11 and a second anchoring rod 16 perpendicularly below the lower reinforcing rod 11.
  • the height of the end plate 14 is slightly less than the thickness of the cantilever plate 3. Since both the end plate 14 and the anchoring elements 15 or anchoring rods 16 are made of stainless steel, the concrete cover is required to be only minor.
  • the reinforcing bars 11 are preferably connected to one another by means of transverse bars 13 running perpendicular to them in order to achieve a stable, transportable component.
  • the cross bars 13 are preferably provided both on the cantilever side and on the support side.
  • the cantilever plate 3 is designed to be thinner, the proper coverage of the anchoring elements 15 is no longer given if they were made of conventional steel. This requires that the anchoring elements 15 are made of stainless steel. However, these additional costs are more than made up for by the other savings, with the additional advantage that one automatically fulfills the building regulations of different countries, which in principle require that cantilever plate connecting elements be made of stainless steel. It is therefore no longer necessary to produce different types depending on the place of use. It is also rather surprising for the person skilled in the art that a cantilever plate connecting element which is simplified in this way and in which the end plate is only provided in the cantilever plate and can be fitted back from the joint area 2 into the cantilever plate brings such improved results.
  • FIG. 2 shows a second embodiment of the cantilever plate connecting element according to the invention.
  • the same reference numerals have been used for the same parts.
  • the entire cantilever panel connection element is again designated 1. It in turn consists of the reinforcing bars 11, which are sheathed with sleeves 12 over the joint area, and penetrate the insulation body 10. Both on the support side (in the drawing on the left) and on the The cantilever side (in the drawing on the right) the reinforcing bars are connected to one another by transverse bars 13 running perpendicular to them. However, the end plate 14 is bent in a U-shape here.
  • the vertically extending portion of the overall U-shaped end plate 17 thus forms the end plate 14, while the legs 18 projecting vertically and directed towards the cantilever plate form the anchoring elements 15 in this case.
  • the legs 18 are considerably shorter than the anchoring rods 16 according to the first described embodiment, approximately the same static strength values can be achieved. With regard to the production, however, this has considerable advantages since the complex welding work for attaching the anchoring rods 16 is eliminated.
  • the entire U-shaped end plate 17 is now advantageously made of stainless steel.
  • both the sleeves and the end plate and the anchoring elements can also consist of other, corrosion-resistant material or even be made of normal structural steel and do not necessarily have to be made of stainless steel.
  • these elements can also be manufactured from corrosion-protected steels, ie steels with the appropriate surface treatment.
  • corrosion-protected steels ie steels with the appropriate surface treatment.
  • the covering of the end plate by the concrete is selected accordingly.
  • the overlap must be at least 3 cm for normal structural steel, at least 1.5 cm for anodized steels and 0 cm for stainless steel, i.e. it must be flush with the cantilever face. In the latter case, the plate will preferably be dimensioned somewhat thicker. But even if a face plate and stainless steel are used, it makes sense to lay them inside.
  • cover plates to the end faces of the floor cover plate 6 and possibly even additionally to the cantilever plate 3.
  • these have no static function but only a protective function and can consequently be considerably thinner than the only end plate 14 in the cantilever plate 3.
  • they could also be made from a different material, e.g. also made of plastic.
