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.
FIG Fig. 5 For the transverse force transmission parallel to the joint various industrially manufactured fasteners are known, as shown schematically in FIG Fig. 5 are shown.
continuous profile elements such as the Pfeifer VS® rail, PEEIEER VS® rail, Betomax Schlaufmax, Philipp rail, and also individual elements ( Fig. 5a ), b)), which are to ensure the transverse force transmission by repeatedly repeated arrangement of reinforcing loops in the precast joint above the other.
the lengths of these rails and strips is for logistical reasons at about 1.20 m.
To reach floor height several rail elements are joined together seamlessly. If fewer loops are needed in a joint, individual deposit boxes are used with only one loop at a distance. By way of example, two and two individual loops may be required in the floor above.
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.
the invention therefore aims to design the connecting element in particular even with compact dimensions such that the tensile forces that arise in the connection as a result of an oblique concrete strut by transverse force stress, are absorbed by rebar elements and forwarded.
the invention provides that in a generic connection element, the penetration openings of two reinforcing loop elements are provided near opposite ends of the storage box.
two opposing reinforcing loops are in the bent-out state (final state) near the respective ends of the storage box.
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.
a connecting element with exactly two reinforcing loop elements represents a particularly preferred embodiment. This is highly variable in use and has, in contrast to known individual elements, a significantly improved, self-contained support 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, particularly 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.
Fig. 1a schematically shows a connecting element 20 according to a first embodiment of the present invention.
the connecting element 20 serves for the transverse force joining of precast concrete elements to a joint with transverse forces parallel to the joint longitudinal direction and comprises a storage box 1 and two bendable reinforcing loop elements 3.
the storage box 1 has an elongated, hollow box-like shape with a length L and two longitudinal ends 1a, 1b.
a storage box floor 1c two openings 1 ', 1 "are provided, on which the reinforcement loop elements 3 penetrate the storage box 1.
the reinforcement loop elements 3 may be, for example, beta steel bars or flexible cable elements which are connected at their free ends via a clamp 2, sleeve or the like.
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.
