Device for tensioning conductors or the like.

, _{Mat <v} ,

The innovation relates to a device for tensioning conductor cables or the like, in which a device that is closed on all sides HoM cylinder, to which anchoring parts are attached, each with an opening on both end faces for the lead rope to be tensioned to pass through and one on the outer surface provided pouring opening, applied to the wire rope or the like is.

For the tensioning of conductors or the like. became so far mainly clamps used to achieve the necessary static friction with considerable contact pressure on the rope or the like. to press.

It is usually required that the clamps can transmit a force which should be greater than 9Qf _{0 of} the rope breaking load. Since the coefficient of friction between the rope and the clamp is not very large, the contact pressure must be according to the equation

- 1 -

P = / U. N

(P = frictional force, / U = coefficient of friction, N-Anpreßdruek) be very large. This often makes such anchor clamps very heavy and expensive. Furthermore, changes in the clamping forces occur over time due to the shrinkage of the rope, which can lead to the clamp becoming loosened. The clamps based on friction have therefore not been able to fully satisfy.

The novelty is that within the Piece of the conductor cable located in the hollow cylinder, unscrewed, embedded in cast resin and connected to the hollow cylinder by means of this. This turns the entire surface of the rope into a Power transmission used. This is particularly important with the usual ropes made of a large number of wires, since this encompasses all of the individual external wires on their entire surface. The previously known terminals on the other hand have only line contact with the external wires.

Plastics are used as semolina, which have a have great adhesive power and harden quickly. This applies in particular to casting resins »

If the casting compound used shows a large amount of shrinkage when it hardens, the two-part joint is used Clamping body inserted an intermediate layer and the inside of the cavity with a sticking of the cured Resin preventive agent provided. After pouring and curing of the resin, the two halves of the

Clamping body separated, the intermediate layer removed and the two halves clamped together again. The shrinkage that occurs during curing is largely taken into account, so that the clamping body rests tightly against the solidified casting compound and transfers the forces resulting from the guy ropes to the casting compound. To a gradual transition of the power flow to reach from the casting body to the clamp body, the cavity having grooves extending along the circumference can ve ± - will see.

Another advantage of the device according to the innovation compared to all known clamps is that the device is independent of the shape of the surface of the ropes or cables, and still transmits power via the entire outer surface of the wires and not, as is usually the case with the known terminals, just line contact takes place. Above all, there are also all the difficulties associated with the known devices due to the presence of the Opposite helix occur in omission.

In the drawing shows Pig. 1 is a diagram of the previously used friction clamps, with 1 representing the rope, 2 and 3 representing the two parts of the clamp. These two halves of the clamp are pressed against the rope by the normal force or the contact pressure N. Pig.2 represents a device according to the invention, where 1 is again the rope, 2 * is a hollow body that can be made in one or two parts, and 3 * are port sets which serve to accommodate the bracing straps A. The cavity

between the hollow body 2 and the rope 1 is now with a Poured casting compound. To ensure good adhesion between the To achieve cured casting body and the rope is the same before pouring with an appropriate means easy to clean.

In the case of conductor cables which consist of several layers of wires, as shown in FIG. 3, the power transmission to the individual layers of the rope take place in that the sub-cables are removed in stages, whereby each layer of the power transmission is involved. The more surface is covered by the casting compound, the more force can be transmitted » In the case of ropes consisting of several layers, as shown in Fig. <£ shows, the anchoring force can therefore be increased even further, in that the ends of the stepped cut layers are still bent open, thereby increasing the surface area the rope is more firmly connected to the tensioning clamp.

If the appropriate circumstances mean that the Clamp is necessary, so the cast body must be completely removed if there is a slight shift. Got to clamp around a big one Piece are moved, it will mostly not bother the original cast body without leaving the clamp body on the rope,
