Definitions
- the invention relates to a bundled tendon consisting of a plurality of plastic-coated tendons, preferably running parallel to one another.
- the tendons mentioned are particularly intended for prestressing concrete in prestressed concrete structures. However, they can also be used for other purposes.
- Another object of the invention relates to a method for producing the bundled tendon.
- the object of the invention is to produce a bundled tendon in which the tensioning elements are connected to one another in a simple manner and with little work.
- the object is achieved in that the clamping elements of the tendon are glued or welded at least at longitudinal intervals at the point of contact of the casing by the action of heat.
- the plastic sheathing is softened by electrical resistance heating in a continuous process and subjected to pressure. Further details of the invention will be explained in more detail with reference to the drawing, in which three exemplary embodiments of the bundled tendon according to the invention are shown.
- FIG. 1 shows a cross section of a band-shaped bundled tendon, which consists of four adjacent plastic-coated strands,
- Fig. 2 is a plan view of the bundled tendon of FIG. 1 and
- strand 1 denotes a strand, which consists of a central wire 1 'and six wires 1 "surrounding it, wherein the wires 1 ⁇ 1" can be connected to form a braid.
- the strand 1 is embedded in an anti-corrosion compound and encased in a plastic sheath 2.
- several strands 1 can also be present in the sheathing 2, wires, rods or the like being used instead of strands. can kick.
- the tensioning elements in the present case the sheathed strands 1, 2 are connected at a distance from one another by gluing points 3.
- the distances B between the glue points 3 are greater than the respective lengths A of the glue points.
- the distances B can also be smaller than the lengths A.
- the adhesive points 3 can also extend over the entire length of the clamping elements.
- a material is preferably used for the wrapping, which is adhesive at about 200 ° C. what HDPE (polyethylene) is suitable for.
- the casing 2 is softened at intervals in the continuous process by electrical resistance heating and a connection is created by subsequent or simultaneous application of pressure, which results in the desired bonding in the course of the subsequent cooling.
- the cooling can be done simply by the influence of the ambient air or by artificial cooling methods.
- the configuration of the tensioning elements can be chosen arbitrarily, the gluing points 3 being produced at the tangential contact points of the adjacent tensioning elements by the described method. It is possible, as shown in FIG. 3, to group four clamping elements into a bundle in which the center points of the clamping elements are arranged in the corners of a square.
