Definitions

  • the precast concrete parts In order to build supporting structures of a building made of precast concrete parts, the precast concrete parts must be connected to each other with a force fit.
  • Disc-shaped wall elements are connected to each other or vertical supports on vertical joints.
  • Vergussnuten At the end faces of the elements corresponding Vergussnuten are arranged on the basis of connecting elements are arranged with storage boxes containing fold-out reinforcing elements.
  • These reinforcing elements can consist of both reinforcing steel and flexible rope elements.
  • Such fasteners are for example in the WO 03/008737 disclosed.
  • the individual elements are, for example, the Pfeifer VS® box ( Fig. 5a )) and the Philipp connection loop ( Fig. 5b )) to disposal. Both have in common that it is an elongated storage box, at one end of a rope loop is arranged, which can be stored inside the storage box. The overall length is essentially matched to the one loop and much shorter than the rails and bars.
  • the individual boxes are arranged at the bottom of the Vergussnut, and the opposing loops are folded out and connected overlapping by the introduced and hardening mortar.
  • the invention is based on the finding that in compact fasteners with only one reinforcement loop or at the free ends of rail-like fasteners with transverse force stress no balance of power adjusts, in which the essential tensile forces are absorbed in the connection by reinforcing elements.
  • each individual connection element according to the invention a self-contained support behavior in which due to lateral force stress an inclined compression strut can form in concrete, which can be supported at their (imaginary) ends on the reinforcing loops of the connecting element to initiate excessive tensile forces in to avoid the concrete or mortar.
  • an inclined compression strut can form in concrete, which can be supported at their (imaginary) ends on the reinforcing loops of the connecting element to initiate excessive tensile forces in to avoid the concrete or mortar.
  • a harmful cracking in the connection area can be effectively prevented, which in addition to the load capacity and the durability and rigidity of the compound significantly increased.
  • the connecting element according to the invention has a simple construction and can be used without any change in the previous construction process without problems.
  • the connecting element according to the invention with exactly two reinforcement loop elements can be used highly variably and, in contrast to known individual elements, has a significantly improved, self-contained load-bearing behavior.
  • the maximum distance of the near-end penetrating openings from one end in the longitudinal direction of the storage box is less than 0.5 times a loop length by which the reinforcing loop elements project from the storage box in the bent-out state.
  • a particularly compact connection element is provided.
  • a concrete compression strut forming as a result of transverse force stress can be effectively supported at the near ends of the storage box with the perforation openings and thus the installed reinforcing loop elements near the edge, whereby the load-bearing behavior of the connection element is further improved.
  • the maximum distance of the proximal penetrating openings from one end in the longitudinal direction of the storage box is less than 0.25 times, more preferably 0.1 times the loop length.
  • the length of the storage box is less than 2.5 times a loop length by which the reinforcing loop elements protrude in the bent-out state of the storage box.
  • this configuration also ensures that the reinforcing loop elements in the installed state are sufficiently close to each other so that the inclination of a pressure strut between the reinforcing loop elements does not become too low and therefore the compressive forces that occur do not become excessively large.
  • An even more compact connection element is obtained according to the invention if the length of the storage box is less than 1.5 times the loop length.
  • the connecting element according to the invention can be used individually or in combination with similar or different types of connecting elements. In this way, the carrying behavior of the overall connection is advantageously influenced by a locally limited measure.
  • the reinforcement loop elements 3 may be, for example, rebars or flexible cable elements which are connected at their free ends via a clamp 2, sleeve or the like.
  • the length L of the storage box is designed such that the reinforcing loops 3 can be easily accommodated inside the storage box 1, as in FIG Fig. 1a shown.
  • the length L of the storage box 1 is slightly less than 2.5 times the length of the loop 1.
  • FIG Fig. 2 schematically shown in a perspective view. This is different from the one in Fig. 1a shown first embodiment by profiling, which are provided in the form of recesses 12 in the storage box floor 1 c. In this case, the recesses 12 are provided in the present embodiment adjacent to the penetration openings 1 ', 1''.
  • FIG. 2 the connecting element 20 with bent by the length of 1 Reinforcement loop elements 3, ie in the final state, which occupies the connecting element in a combination of precast concrete parts.
  • the loop length 1 serves here, as in Fig. 2 shown, the storage box floor 1c.
  • FIG Fig. 4 A connection of precast concrete parts using the connecting element 20 according to the invention is shown schematically in FIG Fig. 4 showing both a vertical and a horizontal sectional view of the connection.
  • the connecting elements 20 according to the invention are provided in end-side potting grooves 11 of precast concrete elements 5 to be joined together.
  • the precast concrete elements 5 are placed side by side with their end faces in such a way that a gap 10 forms in the region of the grouting grooves 11 and is later filled with grout.
  • the reinforcing loop elements 3 are bent out of the custody boxes 1, so that the reinforcing loop elements 3 of opposing connecting elements 20 overlap.
  • a mounting bar 8 made of reinforcing steel is guided by the overlaps. Finally, the grouting of the joint is made to connect the finished parts 5 non-positively with each other.
  • the connecting elements 20, as in the upper part of Fig. 4 can be seen in the vertical section, preferably evenly arranged over the precast concrete elements 5.
  • a model for the in the range of two interconnected by connecting elements 20 precast concrete 5 adjusting behavior is schematically in Fig. 3 shown.
  • a transverse force stress Q whose effective direction is indicated schematically by arrows 6 in FIG Fig. 3 is specified, formed between the precast concrete 5 in the grout or concrete a pressure field, by a inclined concrete strut 7 can be modeled.
  • the model, inclined concrete strut 7 is supported at its ends on the storage boxes 1 of the connecting elements 20, wherein both the Verwahrkastenenden 1 a, 1b and the recesses 12 of the deposit box floor 1 c contribute to improved support and load transfer of the strut 7.
  • the forces 5 aroused by the strut 7 must be taken up and down.
