Definitions
- the invention relates to a method for the subsequent insertion of push-through connections in hardened concrete sleepers, which is drilled from both sides to form a stepped bore.
- Push-through connections are used to anchor elements that are to be mounted on the surface of the concrete sleeper, in particular rail support points for switch sleepers.
- Regular turnout sleepers are sleepers that are manufactured in the factory according to the turnout design with the appropriate length and above all with precisely positioned push-through connections. Consequently, they are sleepers with individual dimensions that depend on the turnout geometry. These turnout sleepers are usually created in the long fitted bed. So-called template sheets are inserted on the underside of the formwork, which are provided with holes in which the push-through connections are fastened before the concreting process. The holes are drilled exactly according to the point coordinates. The dimension for shrinkage and creep of the sleepers is also taken into account in the borehole coordinates.
- the invention is therefore based on the object of providing a method for simple subsequent insertion of the push-through connections in already hardened concrete sleepers, that is to say in the "raw" concrete sleepers supplied to the installation site, which ensures the exact positioning of the push-through connections as in the factory production.
- the sleeper surface is applied with a marking protruding over the bore for precisely fitting a template plate with a fitting hole aligned with the axis of the bore, in order to hold the push-through connection attached to the template plate exactly in the axis of the bore to the potting compound introduced from the bottom is hardened.
- a thinner hole being drilled from the top the diameter of which is slightly larger than the outside diameter of the push-through connection, that is to say the plastic sleeve surrounding the actual screw, and a blind hole which is larger in diameter from the bottom, the forms the receiving space for the clamping nut of the push-through connection, in the simplest case, a marking is applied to the threshold, which comprises a line which has two additional markings for the edges of the template plate on both sides of the marking for the center of the bore.
- the bore of the template plate should be equal to the diameter of the threaded head of the push-through connection and the casting sleeve surrounding it can stand up for alignment on the underside of the template plate. If the stencil plate is attached to the threshold by means of clamping claws and the push-through connection is pushed through from below, it can be screwed down using a threaded nut.
- this dressing can be achieved in the simplest way.
- the threshold is turned upside down and the grouting takes place from the underside.
- the nut which is only used for provisional fastening, can be removed again.
- the template plate is preferably held on the threshold by means of clamping claws and the template plate is lifted off. In this case there is then a push-through connection arranged exactly in accordance with the recorded positioning in the sleeper, the installation accuracy of which does not deviate in any way from the accuracy with which such push-through connections are usually introduced in the manufacturing of the sleeper.
- FIG. 5 is a plan view of the top of the threshold with a template plate attached to it by means of screw clamps,
- FIG. 6 is a partial perspective view of the threshold with the push-through connection passing through it and fastened by screwing to it,
- Fig. 7 is a bottom view of the threshold after inserting and aligning the push-through connection using the template plate and
- Fig. 8 shows a section through the threshold with the fully cast plug-in connection before removing the template plate.
- Fig. 1 shows a plan view of a "raw" threshold with respective minimum intervals, and marks 2 for later be introduced through plug connections.
- these marks 2 are shown in detail. It. These are a direction indicated by a cross with Kreis 3 exact position of the axis of the push-through connection, as well as a horizontal line 4 emanating from it, on which additional markings 5 are indicated on both sides, which correspond to the position of the side edges 6 of the template plate, which will be discussed in more detail below
- This is done by first introducing a thinner through hole 10, which is used to receive the front shaft section 8 of the push-through connection 9, from the top of the sleeper, whereupon after turning the sleeper, a blind bore 11 with a larger diameter is introduced from below which receives the head of the push-through connection 9 surrounded by a plastic sleeve 12.
- a stencil plate 13 is attached using screw clamps 14 on the upper side 15 of the threshold, the alignment using the markings already mentioned and on the square stencil plate 13 arranged, forming a crosshair marking notches 16 and 17. All you need to align is the notch that runs parallel to the marking line 4.
- the corresponding marking notch 16 is aligned exactly on this line and the template is placed so that it lies exactly with its outer edges between the additional markings 5.
- the center of the recess 18 of the template plate is arranged exactly at the point at which the marking 3 for the axis of the push-through connection was originally located.
- the diameter of the recess 18 corresponds to the diameter of the threaded front part of the push-through connection which is inserted from the underside after the previously described alignment of the template plate, whereupon the protruding threaded part is screwed tight using a fastening nut 19.
- the plastic casting sleeve 21 surrounding the actual metallic shaft 20 of the push-through connection stands on the underside of the template plate 13, so that when the nut 19 is screwed tight, the push-through connection with its axis is exactly in the desired position
- Original axis position is arranged according to marking 3 and at the same time the exact vertical position, that is, the parallelism of the push-through connection to the bore axis of the stepped bore 7 is given.
- the threshold is positioned upside down and the space 25 between the push-through connection 9 and the stepped bore 1, consisting of the bore sections 10 and 11, is poured with a grout.
- the mounting nut 19 is loosened and, after the screw clamps 14 have been loosened, the template plate 13 is removed.
