Definitions

  • the invention relates to a cap nut made of plastic with an internal thread for a tie rod provided with a complementary external thread, in particular for screwable connection of precast concrete parts.
  • a screw connection in which a component using a mounting bolt that has a metric thread has, can be attached to a component made of concrete.
  • a component using a mounting bolt that has a metric thread has, can be attached to a component made of concrete.
  • To a nut is cast in half in the precast concrete element and sits the other half in a cap nut-like, also concreted in Element, the mother and this element together being a cap nut form.
  • the opening of the Mother is in the concrete part due to a lost sleeve serving as a placeholder protected from the penetration of concrete into the thread of the nut.
  • the other nut side is covered by the cap nut-like element, so that no concrete can penetrate the mother here either.
  • the placeholder sleeve should also serve to armor the concrete passage and also load-distributing for the parts to be fastened that are pressed onto the precast concrete part Serve element.
  • the torque should go from the mother through her outer hexagon shape can be transferred to the concrete part. Because the mother is obviously made of metal, it can when screwing in the bolt not be spread.
  • the outer circumference is offset by 90 ° in the axial direction, in one axis divided into several sections and staggered in the longitudinal direction Spacers attached. These are meant to be both vertical positioning of the anchor in the concrete sleeper, as well as one appropriate resistance against twisting of the dowel when inserted the threshold screw. So when concreting no concrete can penetrate the dowel, this dowel has a floor on. The entire plastic sleeve is made in one piece.
  • This repair dowel has several disadvantages. Due to the shape of the internal and external thread there is a high notch effect, so that the pull-out resistance is relatively small due to its shape. By choosing the material, namely relative soft polyethylene, the sleeve is also stretchable and deformed under tensile load. Another problem is the four wings that are used in the usual injection molding in series production a multi-part mold require that must also be provided with undercuts, since the Ribs are divided several times.
  • a dowel according to DE-PS 30 39 931 is designed for series production which has a pointed thread on the inside but a round thread on the outside and so forms a so-called shaft dowel, which in a formwork can be used for a precast concrete element and at the same time the essential requirements to the injection molding.
  • Such an anchor can be used with a Make two-part injection mold. For installation in a potted Precast concrete would have to include the opening and the floor Seals are provided.
  • All dowels have in common that they are either material-related or shape-related have a relatively low pull-out strength or tensile strength and also stretch a lot.
  • the metal nut has contact corrosion to count. This metal nut can be replaced if necessary what with permanently installed and calculated for life Precast concrete parts, especially building parts or tunnels possible that are under constant static load.
  • the invention is therefore based on the problem of a screw connection from bolt and nut and a cap nut that can be used for it find the lifespan corresponding to the lifespan of the structure has and without special assembly problems even by inexperienced Forces can be used. Furthermore, the one realized with the cap nut Screw connection also a high pull-out strength and tensile load in the have installed condition. In addition, the cap nut is said to be simple be producible.
  • the concretable cap nut made of polyamide with an admixture of 10 to 45% by weight of glass fibers and UV stabilizers have an internal thread for complementarily designed tie rods with trapezoidal or round threads on and an essentially cylindrical, concentric outer circumference, the radially over the in a longitudinal median plane of two Extent extending from the opening and the bottom of the cap nut spaced ribs, as well as a variety in the axial direction the cap nut interrupted successive recesses at least one between the rib and the opening is arranged, the number of returns in a defined ratio stands for the number of uniform threads of the internal thread.
  • the invention is based on the knowledge that polyamide is not water absorbs and is essentially resistant to hydrolysis.
  • Glass fibers can also increase fatigue strength and elongation be reduced again.
  • 10 to 45 %, preferably about 25 to 40% glass fibers as well as carbon black or others suitable materials for UV stabilization during storage and, if necessary, further additions to the masterbatch, which also includes the Containing UV stabilizer can influence the manufacture of the cap nut the fatigue strength can be taken.
  • cap nuts have a positive fit and frictionally during concreting in the precast concrete to anchor, the form fit through corresponding undercuts on the outer contour of the cap nut analogous to that from the prior art Technically known dowels for concrete sleepers is to be trained.
  • the cap nut according to the invention is also sufficient in their shape the conditions for a simple injection molding in divided Shape. This shape division is along a longitudinal median plane of the plastic part filled in so that only one division in this longitudinal median plane is required to core the plastic part.
  • This method of production can be supported in that the recesses are mirror-symmetrical to the longitudinal central axis and are more preferred Shape all returns are the same. This simplifies tool manufacture and the gutting when spraying, as well as the spraying itself the evenly distributed material parts.
  • the number of returns is in a fixed ratio or is proportional to the number of threads of the internal thread of the cap nut, insofar as this are uniform, i.e. are load-bearing threads, the cap nut has about 10 to 50 load-bearing threads and the number of recesses is about a factor of 2 to 3 smaller. This number of returns therefore allows a direct conclusion to be drawn about the load-bearing capacity or tensile strength to the cap mother.
  • the permissible tensile load on a nut results from the load-bearing circular area of a thread x permissible specific surface pressure on the thread x the number the threads.
  • the number of returns of the number corresponds to the length because these returns regularly over the length the cap nut are distributed, on the one hand there is an analogy between the length of the cap nut and the number of undercuts and on the other hand, an analogy between the number of gears and the number of Setbacks.
  • the length corresponds to the once calculated cap nut of its transferable tensile load, or on the other hand, the number of undercuts corresponds to the number of gears and thus the internal tensile load of the cap nut against pull-out strength and the corresponding strength of the connection between concrete and cap mother.
  • the screw connection should be designed so that the connection two precast concrete parts, one of which is penetrated by the screw, while the other as anchoring part, i.e. the in the precast concrete sitting cap nut serves as anchoring.
  • the screw should be a smaller one As the cap nut, all threads are always stretched be evenly loaded, if there is any stretch at all is coming.
  • the cap nut with a substantially cylindrical outer contour 1 has regular concentric recesses 2, which are between the in Longitudinal median plane 10 (Fig. 2) located two ribs 3 around each extend half the circumference of the cap nut. One of those returns, with the number 9, lies between the opening 5 of the cap nut and the beginning of the rib 3 to a complete positive connection in the to be able to produce the precast concrete shown.
  • the rib 3 is from the same reason also spaced from the bottom 4 of the cap nut.
  • Inside the cap nut has a round thread 6 which leads to the opening 5 the nut is formed as an enlarged thread 7, the Core diameter of this threaded part is designed as a cone 8.
  • the Entire cap nut is made in one piece from polyamide with an admixture of 30% glass fiber and 1% carbon black were made in an injection mold, which is divided in the median longitudinal plane 10.
