Abstract
The invention relates to a method for winding a spiral bar after the outer surface of a diagonal rope body is wound with a PVF fluorating film adhesive tape. The invention is characterized in that: the method has the technique steps as follows: the steel tendon of the diagonal rope is carried out hot extrusion high density polyethylene and then is wound and covered with a layer of PVF fluorating film protection adhesive tape in a spiral way, finally, the PVF adhesive tape is externally wound with the spiral bar. By adopting the method after being wound with the PVF fluorating film adhesive tape, the outer surface of the diagonal rope body is wound with the spiral bar, the invention not only exerts the excellent weatherability of the PVF adhesive tape, ensures the durability of the diagonal rope, but also at the same time makes use of the hydrophobic nature of the surface of the PVF adhesive tape and the wound spiral bar to well restrain the shock excitation of the diagonal rope for resisting wind and rain.
Description
Technical field
The present invention relates to a kind of inclined cable external surface and twine winding screw muscle method behind the PVF fluoride membrane adhesive tape.Belong to the bridge cable technical field.
Background technology
Usually, the anticorrosion of suspension cable mainly is to adopt high density polyethylene (HDPE) sheath means of defence, produces the rain wind induced vibration phenomenon in order to solve suspension cable simultaneously, then further takes aerodynamic Measures such as embossing or winding screw muscle on the surface, as Fig. 1.Yet suspension cable high density polyethylene (HDPE) sheath uses less than several years and just all cracking in various degree occurred on a lot of cable stayed bridges in the past, and aging phenomena such as breakage in order further to improve suspension cable cable body antiseptic property, have following two kinds of methods by improvement at present:
1, before the hot extrude high density polyethylene (HDPE) parallel wire unit is twined the PVF fluoride membrane adhesive tape, after preventing the high density polyethylene protective coating breakage, moisture and other hazardous substancess enter cable body, as Fig. 2.
2, after the hot extrude high density polyethylene (HDPE), twine the PVF adhesive tape, to improve the suspension cable anti-ultraviolet property, as Fig. 3.
But above two kinds of methods exist following drawback:
First method though can provide another layer safeguard measure after the breakage of high density polyethylene (HDPE) sheath, fails to improve the ageing-resistant performance of high density polyethylene (HDPE), and the ageing-resistant performance of high density polyethylene (HDPE) is a bottleneck of durable cable always at present.
Second method, though well utilized the good anti-ultraviolet property of PVF fluoride membrane adhesive tape, conventional twines outside the high density polyethylene (HDPE) sheath, cannot well bring into play suspension cable anti-wind, rain and vibration performance.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of inclined cable external surface that can improve the ageing-resistant performance of high density polyethylene (HDPE), can well bring into play suspension cable anti-wind, rain and vibration performance again to twine winding screw muscle method behind the PVF fluoride membrane adhesive tape.
The object of the present invention is achieved like this: winding screw muscle method behind a kind of inclined cable external surface winding PVF fluoride membrane adhesive tape; it is characterized in that: the processing step of described method is as follows: earlier the Cable Stayed Steel tow is carried out the hot extrude high density polyethylene (HDPE); spiral one deck PVF fluorinated film protective tapes that is wrapped then, winding screw muscle again outside the PVF adhesive tape at last.
PVF fluorinated film protective tapes has higher intensity, good weather resistance, chemical inertness and resistant performance easy to clean, out of doors can be for the sheath shielding ultraviolet rays, resist the erosion of air, rainwater etc.And have and the pe sheath good adhesive strength, can be attached at the protective sleeve of pulling cable surface fully.Winding screw muscle again outside the PVF adhesive tape is in order to solve the generation of suspension cable rain wind induced vibration.
The present invention is twined winding screw muscle method behind the PVF fluoride membrane adhesive tape by adopting the inclined cable external surface, not only given full play to the good weather resistance of PVF adhesive tape, guarantee the durability of suspension cable, utilized the hydrophobicity of PVF tape surface and the spiral bar energy good restraining suspension cable wind resistance rain exciting of winding simultaneously.
Description of drawings
Fig. 1 is in the past at the structural representation of high density polyethylene (HDPE) jacket outer surface winding screw muscle.
Fig. 2 was for twined the schematic diagram of PVF fluoride membrane adhesive tape in the past to parallel wire unit before the hot extrude high density polyethylene (HDPE).
Fig. 3 was for twined the schematic diagram of PVF adhesive tape in the past after the hot extrude high density polyethylene (HDPE).
Fig. 4 is the schematic diagram of winding screw muscle behind the inclined cable external surface winding PVF fluoride membrane adhesive tape of the present invention.
Among the figure: Cable Stayed Steel tow 1, high density polyethylene (HDPE) sheath 2, PVF fluorinated film protective tapes 3 and spiral bar 4, zinc-coated wire 1.1, be wrapped be with 1.2, color high-density polyethylene sheath 2.1, black high density polyethylene (HDPE) sheath 2.2.
The specific embodiment
Winding screw muscle method behind a kind of inclined cable external surface winding PVF fluoride membrane adhesive tape that the present invention relates to, the processing step of described method is as follows:
Earlier the Cable Stayed Steel tow is carried out the hot extrude high density polyethylene (HDPE), spiral one deck PVF fluorinated film protective tapes that is wrapped then, winding screw muscle again outside the PVF adhesive tape at last is as Fig. 4.
