Description
Technical field
The utility model relates to the suspension cable field of bridge part, specially a kind of 91 preforming main rope of suspension bridge strands.
Background technique
Main rope of suspension bridge strand is the main bearing member of suspension bridge, is made of several high-tensile steel wires, due to hexagon
Section can form stable structure in entire main push-towing rope, therefore the section of main cable strand is generally hexagonal cross-section.Main rope
Stock main specifications have 61,91,127 and 169 etc. it is several, the strand of these specifications can be formed hexagon cut
Face.However main cable strand the positions such as scattered cable saddle, king-tower main cable saddle need integer at the matched rectangular configuration of cable saddle slot, operation
When need manually the main cable strand of hexagonal cross-section is scattered at the construction field (site), place into saddle slot after being organized into rectangular section.
By taking 91 main cable strands as an example, main cable strand 100 is by strand steel wire 11 and the anchor head at both ends 101 as shown in Figure 1:
It constituting, strand steel wire 11 is in turn divided into conventional section 102 that section is hexagon again and section is that rectangle enters saddle section 103, and six
When the tee section of side, as shown in Figure 2: strand steel wire 11 is arranged in 11 layers, and external application twining package tape 12 tightens, and the radical bottom of to top is successively
Are as follows: 6,7,8,9,10,11,10,9,8,7 and 6；Arranged by hexagon it is rectangular after, as shown in Figure 3: be still 11 layers, adjacent two
The strand steel wire 11 of layer is at being staggered and radical differs one, i.e., the radical bottom of to top is successively are as follows: 9,8,9,8,9,8,9,
8,9,8 and 6.As it can be seen that there are three omissions for top layer, as shown in three circle of dotted lines in Fig. 3.This defect will lead to main cable strand
The problems such as internal porosity is excessive, misplaces between steel wire seriously affects the stress-bearing capability of strand, and then shortens the use longevity of bridge
Life.
Currently, bridge starts the preform technique using main cable strand when building, but in the main cable strand of 91 specifications
On encounter compile Suo Wufa formed complete rectangular cross sectional shape the problem of, constrain the popularization and use of this technology.
Utility model content
In order to overcome the drawbacks of the prior art, provide a kind of structure it is simple, it is easy to use, avoid wrong silk disorderly, improve strand

The utility model reaches goal of the invention by following technical solution:
A kind of 91 preforming main rope of suspension bridge strands, including strand steel wire and anchor head, strand steel wire share 91, strand
The both ends of steel wire are each to fix an anchor head, and it is to cut in the middle part of strand steel wire that strand steel wire both ends, which are the conventional section that section is hexagon,
Face is that rectangle enters saddle section, it is characterized in that: further include filler wires and spacer ferrule,
The saddle end that enters of strand steel wire is arranged in 11 layers, and the strand steel wires of adjacent two layers is at being staggered and radical difference one
Root, i.e., successively the bottom of to the radical of acrochordal stock steel wire are as follows: 9,8,9,8,9,8,9,8,9,8 and 6, when top layer strand steel wire arranging,
A strand steel wire setting is successively spaced at three omissions；
A filler wires are respectively embedded at each omission, the section of filler wires is determined as follows:
Using the equal circle of a diameter and strand section of steel wire diameter as basic circle, the lower part of basic circle two sides respectively sets one and stretches to
The fixture block in outside, filler wires be embedded in top layer strand steel wire omission at when, the two sides of filler wires basic circle respectively with top layer
A piece strand steel wire is tangent, the gap between the fixture block insertion top layer of filler wires and secondary top layer two adjacent strand steel wires
It is interior, and the shape of fixture block and the shape in the gap match each other；
The rectangular section outer hoop that strand steel wire and filler wires piece together has spacer ferrule.
The preforming main rope of suspension bridge strand of the silk, it is characterized in that: the opposite medial surface of spacer ferrule a pair be equipped with it is fixed
Position tooth, forms locating slot between adjacent positioning tooth, and each positioning tooth insertion is located at adjacent bilevel two strand steel wires
Between, corresponding every strand steel wire is embedded in a locating slot.
The preforming main rope of suspension bridge strand of the silk, it is characterized in that: further including Reinforced Hoop, Reinforced Hoop hoop is in spacer ferrule
Outside.
The utility model has following technical characterstic:
1. the main rope of suspension bridge strand of the utility model enter saddle section need in factory integer quadrangularly, remaining is six
Side shape；
2. since 91 main cable strands can just form hexagonal cross-section, and the section for entering saddle end is rectangle, 91
Quantity can not form complete rectangle, need to be filled；
3. the filler wires such as steel wire using common circular section influences phenomena such as entering saddle section and can generate at random, nose
The porosity of main cable strand is likely to result in other steel wire fracture of wires after the tight cable stress of steel wire at random, influence main cable strand by
Power ability；
4. filler wires are embedded in close among steel wire respectively using anisotropic section, keep it limited in longitudinal and transverse direction
There is not phenomena such as jumping silk, sleave in system；
5. the saddle section that enters of rectangular section is formed using spacer ferrule and with Reinforced Hoop, while spacer ferrule is equipped in zigzag
Surface, zigzag and the matching of main cable strand sectional dimension.
The utility model provides a kind of preforming cross section structure of 91 strands, and the strand steel wire in rectangular section is vacant
Place increases by three filler wires, solves the problems, such as steel wire omission of 91 strands after being converted into rectangular section.The utility model
Filler wires are designed as profiled-cross-section, filler wires and other strand steel wires is made to form section that is chimeric, integrally fixing mutually,
Phenomena such as preventing steel wire dislocation, sleave.
The beneficial effects of the utility model are: structure is simple, and it is easy to use, it avoids wrong silk random, reduces difficulty of construction, improve
Strand mechanical performance, prolongs the service life,.
