Definitions
- So-called rope clamps are used as the end or intermediate fastening of steel ropes in addition to casting heads, clamping heads and bollards.
- the required pulling force is generated by clamping jaws, which are pressed onto the rope e.g. with screws, springs or wedges.
- This solution is suitable for relatively small forces which the rope elongation over the terminal length is negligible during the build-up of the tensile force.
- the clamps known today are less suitable for tensioning thicker ropes with higher forces because they can damage the rope and harbor certain uncertainties in the transmission of the frictional connection
- the present invention is based on the object of specifying a device with which stretchable tension elements can be gently tensioned, fastened and pulled. This object is achieved by the combination of features of the claims.
- An exemplary embodiment of the invention is explained below with the aid of the drawing
- Fig. 1 is a side view and Fig. 2 is a cross section
- the device is used to fasten, tension or pull a long elastic or stretchy tension element.
- a preferred area of application is the tensioning of steel ropes for supporting structures, e.g. hanging, large-area roofs.
- the tensioned length of the rope plays a major role in its function and dimensional stability.
- New steel ropes unfortunately have a tendency to grow in length within the first few weeks of stress the unpleasant consequence that the newly built hanging structure has to be closed for a few weeks after commissioning in order to re-tension the ropes
- the tensile element slips from the tensile side of the tensile element when the static friction is exceeded until it then wears over the entire length of the jaw, but it cannot be determined in practical use how much force is transmitted per unit length If, on the other hand, the material of the clamping jaws is hard, at least the surface of the tension element is damaged. If the material is soft, it is rubbed off at least on the side facing the pulled rope
- a train acts in the axial direction Z on a steel cable 1 with an axis 2.
- the cable is clamped in the device 10.
- the device 10 has a frame 11 with two frame parts 12, 13 arranged symmetrically to the axis 2 converging wedge surfaces 14
- Two opposing wedges 15, 16 slide on the surfaces 14. These have mutually facing, straight sliding surfaces 17, 18 eg in the form of Dovetail guides, on each of which a row of clamping shoes 19, 20 are slidably guided
- the shoes 19, 20 are limited from the basic position shown in FIG. 1, apart from the rearmost pair of shoes in the direction of pull Z by stops 21 in the direction of pull Z.
- the possible shift 22 of the shoes from its basic position 19, 20 increases linearly in the pulling direction Z.
- the shoes 19, 20 all have the Same length They are attached to the sliding surfaces 17, 18 so that they can be exchanged in order to adapt the device 10 to other cross sections of the rope 1 or other traction elements.
- the shoes 19 are returned to their basic position by springs 23
- the two frame parts 12, 13 are connected to one another in an articulated manner only on one side of the rope.
- the connection is made via a shaft 44 whose axis 45, the axis 2 perpendicularly approximately in the long center of the row of shoes 19 , 20 cuts This ensures that with linearly increasing elongation of the rope 1 in the pulling direction Z and therefore approximately linearly decreasing rope diameter, the same radial contact force acts on the rope 1 over the entire length of the row of shoes 19, 20.
- This effect can, however, also be without Swivel movement, but with relative long expansion screws are approximately reached, which clamp the parts 12, 13 against each other
- the shoes 19, 20 have semi-cylindrical recesses with inserts 46 made of a material that is softer than the tension element to be tensioned or fastened.
- Steel cables 1 are suitable for the inserts 46 made of “soft” materials, for example bearing metal, tin, plastic, etc.
- the cable 1 is inserted from the side between the pairs of jaws 19, 20 and the wedges 15, 16 are tensioned by means of the cylinders 29, 30.
- the cylinders 33, 34 are then actuated, which pulls the rear, fixed pair of jaws 19, 20 in the pulling direction Z. together with the others until the end of their frictional engagement with the sliding surfaces 17, 18 on the rope 1 and therefore stretches it because of the increasing expansion from the back to the front, the front pair of shoes 19, 20 immediately afterwards also the other
- the graduation of the stroke limits 22 is designed in such a way that all shoes 19, 20 rest against their stops 21 when the intended tensile force for the rope 1 has been reached with the cylinders 33, 34.
- the device 10 for fastening a tension element 1 is set, the tension cylinders 33, 34 can be omitted and that Frame 11 can be anchored directly.
- the cylinders 29, 30 need only be used for assembly purposes.
- the device is also suitable for the continuous pulling of stretchable tension elements 1 in that two of these devices 10 are connected in series and alternately carry out gradual pulling movements
- the limits 21 of the displacement movements of the clamping jaws 19, 20 in the pulling direction Z are not absolutely necessary, but are expedient so that with a diameter of the cable 1 that varies over the clamping length, there is nevertheless an approximately uniform distribution of the tensile force over the clamping length.
- the radial pressure of the holders 15, 16 can instead of the clamping surfaces 14 also be done via cylinders directed radially to the axis 2 or via a parallelogram rod, the dead center position of which is close to the maximum tensioned length of the cable.
- Such parallelogram rods can also be connected to one another like the wedges 15, 16 on parts 12, 13 which are pivotable against each other about the axis 45 The pivotability about the axis 45 is, however, not absolutely necessary.
- FIG. 3 shows the variant in which the two rack positions 12 + 13 are not pivotable, but are rigidly connected to one another by means of expansion screws 50 on plates 52 which are spaced apart from one another by a series of rectangular tubes 53.
- the expansion screws 50 are located directly adjacent to the axis 2 side wall 54 of the tubes 53 arranged Due to the eccentric loading of the tubes 53 by the expansion screws 50, the tubes 53 bend slightly.
- FIG. 4 is a device for automatic setting of the stops 21 for de n
- the displacement of the clamping shoes 19, 20 is shown schematically. Control pliers 58 are screwed to the frontmost clamping shoe 19 in the direction of pull Z.
- the rearmost shoes in 19, 20 are rigidly attached to the wedges 15, 16 on each shoe 19
- a triangular control piece 59 protrudes from the control rod 58 against the axis 2.
- the tip angle, the control piece 59 decreases with increasing distance from the front shoe 19.
- Each stop piece 61 has on the side opposite the legs 60 and the surface 62 a wedge surface 64 which is inclined to the axis 2 and which has a corresponding counter surface 65 of the relevant shoe 19 b, 19 c, cooperates
- the control rod 58 is biased by a spring, not shown, against the pulling direction Z into the basic position shown in FIG. 4, in which the stop pieces 61 with their front and rear sides will rest against the legs 60, the surface 62 and the counter surface 65 now the cable 1 is pulled in the direction Z, the front shoe, 19 a, moves away from the rearmost 19 n because of the rope stretching and takes the rod 58 with it.
