Definitions

  • the invention relates to a reinforced concrete steel structure for forming a permanent connection between a concrete component and a steel component.
  • the material concrete, and especially the variant reinforced concrete is versatile as a building material.
  • this building material is not used exclusively, but in combination with other building materials.
  • individual elements or entire assemblies of concrete or reinforced concrete and complementary elements or assemblies of a different material, such as steel, are usually produced.
  • the individual elements or modules must be connected to each other during assembly. This often involves so-called anchorages.
  • US 2005/0115195 A1 shows a reinforced concrete steel structure according to the preamble of claim 1.
  • WO 98/45101 A1 and DE 3 738 524 A1 also show relevant documents.
  • the invention is therefore based on the object of developing a further improved and, moreover, more resilient reinforced concrete steel structure, in particular for connecting a concrete component to a steel component.
  • a reinforced concrete-steel structure serves to form a permanent connection between a concrete component and a steel component.
  • at least one anchoring element formed from an anchor strip is cast into the concrete component such that it projects at least partially out of the concrete component.
  • the exposed section acts as a connecting surface to the steel component and is firmly connected to this.
  • On the side of the connecting surface a number of recesses is provided on the anchor bar, which extend into the concrete component into it.
  • concrete component at least one steel strut braid is introduced as a reinforcement, wherein each recess is penetrated at the anchor bar of at least one steel strut of the braid.
  • the attacking forces thus act less locally and can therefore be better absorbed by the concrete component.
  • the anchoring capacity especially against tensile load, compared to other anchoring systems significantly increased.
  • each recess separates the connection surface into at least two spatially separated subregions.
  • each recess is incorporated as an easy-to-implement lateral recess in the anchor bar.
  • By connecting the anchor bar and steel component in the production of each recess is then supplemented to a kind of eyelet through which passes through at least one steel strut of the steel strut mesh.
  • a loop formed in this way acts as a favored connection point or favored force transmission interface between the concrete component and the steel component.
  • a plurality of regularly arranged recesses in the manner of a row of teeth is provided.
  • a very large number of favored connection points and a uniform distribution of the same can be realized.
  • the transfer of forces acting on the steel component to the reinforcement and thus to the concrete component then takes place correspondingly uniformly.
  • each recess has the contour of a quadrangle or a symmetrical trapezoid.
  • profile strips with an L, T or I-shaped cross section are used as anchor strips.
  • such a cross-section requires a barb-like effect, ie an improved hold of an anchor bar in concrete, and on others it is thus possible to resort to commercially available standard profiled items for the production of the anchor bars.
  • I-, U-, double-T and Z-profile strips as output products are also suitable for the production of two anchor strips in a manufacturing process.
  • the anchor strips are preferably made of steel, in particular of ferritic or austenitic steel. In this context, it is therefore considered advantageous if each anchor bar materially connected to the corresponding steel component, in particular welded, is.
  • a reinforced concrete steel structure according to the invention is due to its load capacity for the construction of a reactor containment vessel, a pressure vessel or a tank container. According to a typical construction, these are constructed of reinforced and possibly prestressed concrete components that form the concrete shell. On the inside of this concrete jacket, a steel jacket, also referred to as a liner, of a number of steel components is provided, which ensures the tightness of the concrete jacket. With the help of anchoring according to the invention, the steel components are finally connected to the concrete components inextricably.
  • the design and construction of the anchoring of the steel containment jacket, also referred to as containment liner, of the reactor containment is of great importance.
  • high standards of anchorage are defined in various standards and guidelines.
  • the anchoring must be able to withstand the forces and stresses that occur during normal operation as well as in the event of an accident and at the same time prevent cracking / crack propagation in the steel jacket.
  • these requirements can be met more efficiently when the steel shell, the anchorage and the reinforced concrete work together in the depth of the anchorage.
  • the anchoring system according to the invention offers the highest degree of effectiveness in this respect.
  • the reinforced concrete steel structure according to the invention with specially shaped anchoring profiles provides an efficient solution for embedding the profiles in the concrete together with an optimized interface to the reinforcement and at the same time great saving potential in terms of manufacturing costs and production times.
  • the use of this system increases the efficiency of anchoring the steel mantle. It can be used both for reactor and other containment containers and gas and liquid containers as well as for pressure vessels.
  • FIG. 1 is the principle of operation of a reinforced concrete steel structure according to the invention recognizable.
  • the longitudinal section shown in detail therein shows a concrete component 1, which is permanently connected by means of at least one anchor strip 2 to a steel component 3, also referred to as a liner plate, designed in the manner of a flat steel plate.
  • a steel component 3 also referred to as a liner plate, designed in the manner of a flat steel plate.
  • anchor strips 2 can be at a certain distance perpendicular to the plane behind each other, which does not appear from the figure.
  • a half of a steel profile strip is provided in this embodiment, which by dividing one of the in FIG. 2 and FIG. 3 shown standard commercial profiles 4, 5 can be produced.
  • This is preferably chosen so that as a result along both halves of a kind of row of teeth is formed by recesses or spaces separated teeth.
  • the shape of a symmetrical trapezoid was chosen as an example.
  • Both anchor strips 2 can be considered substantially equivalent. They differ only by a displacement of the row of teeth in the bar longitudinal direction 6.
  • any suitable separation method can be used, such. Cutting, shearing, punching and related processes such as laser cutting.
  • each anchor strip 2 has a strip-like and preferably plane-of teeth and recesses formed from the corresponding upper or lower flange of the standard profile, i. Perpendicular to the plane of projection outwardly projecting support leg 8, which rests in the final assembly state of the anchoring system in the concrete component 1 and therefore acts more or less as a barb.
  • the recesses in the transverse direction 11 are not quite zoomed up to the holding foot 8, but it remains in each case one connected to the holding foot narrow web thirteenth
  • the majority of the remaining anchor slat body in the final assembly state is encapsulated or encapsulated by the concrete of the concrete component 1.
  • the exposed tooth crowns 9 serve as part of a connecting surface in the anchoring system according to the invention.
  • welds are preferably applied to both sides, at the abutting edges of anchor strip 2 and steel component 3. Due to the Aussparrept between the teeth, the total length of the connecting surface 9 in the longitudinal direction 6 is only about 1/3 of the total length of the anchor bar. 2
  • a braid of steel struts 10 is incorporated as a reinforcement.
  • the braid has several layers which are stacked in an alternating sequence ABAB in the transverse direction 11 one above the other. In FIG. 1 exactly four layers are shown. However, a different, especially larger number of layers may also be advantageous.
  • the steel struts 10 assigned to a layer A are arranged parallel to one another and parallel to the longitudinal direction 6 of the anchor strip 2 and perpendicular to the steel struts 10 of a layer B which run perpendicular to the plane of the drawing.
  • the steel struts 10 are preferably connected to each other.
  • the type of connection can vary depending on the application. Particularly expedient variants are gluing, welding or wrapping with wire.
  • the steel struts 10 of two directly superimposed layers AB can also be intertwined by, for example, the perpendicular to the plane extending steel struts 10 are alternately passed above and below them immediately adjacent and extending in the longitudinal direction 6 steel struts 10.
  • each interdental space of an anchor bar 2 is formed into a kind of eyelet 12.
  • a steel strut 10 of the steel braid mesh passes through such eyelet 12, so that at this point a power transmission according to the objective is possible.
  • the interdental spaces passing steel struts 10 are respectively on the inner web 13 of the anchor bar 2.
  • Each interdental space can also be penetrated by more than one steel strut 10, or exceptionally by none, provided that at least some interstices of the anchor bar 2 are interspersed accordingly by steel struts 10. If, for example, tensile forces act in the transverse direction 11 on the respective anchor strip 2, then this is not only held in the concrete via its retaining foot 8, but is additionally anchored over the upper two layers of the steel braid braid.
  • the steel strut braid has four layers of crossed and optionally partially intertwined steel struts 10, wherein the steel struts 10 of the in the direction of penetration into the concrete component 1 lowest position perpendicular to the plane and under the support leg 8 of the anchor bar 2, parallel to the further above the interdental spaces interspersed steel struts 10 are passed over.
  • Some of the longitudinally extending to the anchor bar 2 steel struts 10 of the next higher layer can be arranged such that they are supported from above on the support foot 8 and thus do not touch the perpendicular thereto steel struts 10 of the lowermost layer directly.
