Description
Technical field
The present invention relates to the decoration drag-line that a kind of bearing capacity is little or do not stress, especially a kind of Landscape Bridge drag-line and preparation method thereof.
Background technology
Since 21 century, China's rapid economic development, urban construction enters a peak period, require also more and more higher to appearance of city, the beautiful scenery be together designed to intersperse city temples of view bridge, increasing municipal engineering have the demand of this respect, and designing unit also starts to design various view stayed structure in a large number and applies in engineering.
The cable body structure that the most of bridge of current China adopts mainly is divided into hawser and steel strand rope, and the drag-line of these structures is mainly applicable in the larger medium-and-large-sized bridge construction of bearing capacity, cannot meet in Landscape Bridge structure, Suo Li little and the large special landscape demand of diameter of wire cord.
Prior art adopts two schemes to realize Suo Li little and the large object of diameter of wire cord usually:
1, by aperture position Suo Fanfu extrusion molding to increase diameter of wire cord (see Fig. 5), in figure, 14 is guiding principle twisted wire, 15 be multilayer PE cover;
2, increase the outer tube of view outward at aperture position individual layer PE cable body, the gap between individual layer PE cable body 17 and outer tube 18 uses the simple type locating ring 16 fixing (see Fig. 6-1 ~ Fig. 6-2) of segmental.
But above two kinds of ropes are used for Landscape Bridge at present following deficiency:
Aperture position drag-line is squeezed PE to increase the scheme of diameter of wire cord by scheme one repeatedly, and finished product rope, owing to being subject to the restriction of PE extrusion process, cannot realize the design requirement of multilayer or too thick PE layer, easily occurs that PE ftractures, and the too thick cost of manufacture of PE layer is high; Secondly increasing PE layer can cause cable body Unit Weight to increase, thus causes wind to shake sharp increase in small-sized Landscape Bridge because Cable forces is little, is unfavorable for the demand of the attractive in appearance and antidetonation of drag-line.
Scheme two strengthens the words of landscape effect at the outer addition sleeve pipe of aperture position cable body, excesssive gap between cable body and sleeve pipe, and the device for positioning and securing of segmental is difficult to the centering and the location that realize whole free segment cable body and outer tube, also keep away unavoidable sleeve pipe shortage and effectively support the vibrations and buckling phenomenon that bring, view requirement cannot be met; Therefore, a kind of drag-line being specially adapted for Landscape Bridge of exploitation is badly in need of.
Summary of the invention
The object of this invention is to provide and be a kind ofly applicable to stressed little or decoration drag-line---" a kind of Landscape Bridge drag-line " that do not stress in urban fringe and park, this Landscape Bridge drag-line solves corrosion resistance, the water proofing property of single presstressed reinforcing steel, the view performance of external sleeve pipe can be realized without outer PE drag-line, and solve the problem preventing external sleeve pipe from shaking, the Landscape Bridge drag-line of this structure has anchoring property reliably, makes, installs and change the advantages such as rope easy construction; To solve the problems referred to above that prior art exists.
For solving the problem, the technical solution used in the present invention is: a kind of Landscape Bridge drag-line, comprise cable body and two the anchoring black boies being positioned at cable body two ends, described cable body comprises the PE Prestress tendon that n root single PE presstressed reinforcing steel is formed and the outer tube be positioned at outside the single PE Prestress tendon of n root; Each anchoring black box comprises anchoring gripping section and sealing corrosion section;
