Definitions
- the invention relates to a covering of prestressing elements according to the preamble of claim 1.
- AT 396 153 B is a tendon with several tension members and known at least one cladding tube, which consists of two parts, which are connected by a fold connection are.
- the object of the invention is simple and with little To create cost-related wrapping for which the Raw materials to the place of manufacture and space-saving simple means can be brought.
- this object is achieved by the measures Claim 1 solved.
- Such tapes can be brought to the manufacturing site in spools where they are passed through a knife system, which divides the tape into strips.
- the tendons can be, for example, the tendons be divided into broad and narrow strips, the broad ones Strip the two opposite broad sides, and the narrow stripes the two narrow sides of the band cover.
- Butt welding is the preferred weld, for example with a welding mirror, a welding knife, one Welding plate or the like Due to the possibility of supplying the Cover material in the form of reels, the high transportation costs, which with the previously known supply of the starting material for the production of covers in the form of saved on elastic plastic.
- the tendons can be strands, wires, monostrands or monowires his.
- the casing 1 denotes the tendons and 2 the casing, which made of plastic or the like elastic material is made.
- the casing 2 according to FIG. 1 becomes a plastic band cut into four longitudinal strips, two strips each 3, 3 'with the length L1 and two strips 4, 4' with the Length L2.
- the longitudinal strips 3, 3 ' are along the broad area and the strips 4, 4 'over the end tendons 1', 1 " placed and butt welded at the joints, so that in In the present case, four butt welds 6 arise.
- the Welding can be carried out with a welding knife indicated with 5. There is the option of making the welding knife stationary to arrange and the covered tendons 1 to the To pass welding knives or vice versa. Through the welding knife the joints are heated to about 240 ° so that the Plastic edges melted and through side pressure application get connected.
- the prestressing element according to FIG. 2 has the bundle of tendons 1 hexagonal circumference, on which six strips 3A of equal width placed on and similar Way welded at the joints at 6 as previously described become.
- the welding knives can be in any shape, e.g. as Welding mirror, welding plates or the like be trained.
- Plastically deformable elements are used primarily for curved ones Parts of the envelope 2 used by these parts Heat can be deformed and the desired curvature of the Accept envelope 2, after which they retain their shape after cooling.
- the strips 3 etc. can be along the edges to be welded butt or overlap.
