It is prefabricated rectangular at saddle, directly strand can be installed into cable saddle when strand enters saddle, effective protection main cable strand coating is not damaged
Wound, the scene of raising put the quality and effect of rope；Therefore main cable strand using the technique of batch production preforming it is more convenient, safe,
Quickly.
Preforming main cable strand needs to ensure the preforming main rope that cross section is indeformable, common in rope work progress is put
The shaping equipment of stock is relatively simple, and it is unstable that main cable strand is easily caused cross section after being clamped, and can cause main cable strand internal beam stock
Misplace between steel wire, cross-sectional deformation causes steel wire to be damaged.
Utility model content
In order to overcome the defect of prior art, there is provided a kind of simple structure, easy to use, clamp are accurate, strand is indeformable
The fixture not being damaged, the utility model discloses a kind of special clamp of suspension bridge preforming main cable strand.
This utility model reaches goal of the invention by following technical solution：
A kind of special clamp of suspension bridge preforming main cable strand, including hoop body pair, is characterized in that：Hoop body is secondary including the first hoop
Body and the second hoop body, the first hoop body and the second hoop body are all connected the base structure of one block of side plate respectively by the homonymy of two opposite side of base plate
Into the cross section of the first hoop body and the second hoop body is all " Contraband " font, is respectively provided with least on the top margin of first two blocks of side plates of hoop body
One the first engaging piece, at least one that the first engaging piece is selected in breach and projection, on the top margin of second two blocks of side plates of hoop body
It is respectively provided with least one second engaging pieces, from least one in breach and projection, the first engaging piece lacks the second engaging piece
The projection or breach of mouth or projection and the second engaging piece matches each other, and the first hoop body and the second hoop body are mutual with top margin by side plate
Alignment pieces together the hoop body pair that cross section is " mouth " font, and during split, each first engaging piece and second engaging piece are with prominent
The mode of the embedded breach of block is intermeshed；
First hoop body and the medial surface of base plate both the second hoop body are designed with corrugated card face, and card face is by least three
Section circular arc head and the tail are sequentially connected composition, and the circular arc is all with cancave cambered surface towards the secondary center of hoop body.
The described special clamp of suspension bridge preforming main cable strand, is characterized in that：The central angle for constituting the circular arc in card face exists
30 °～90 °.
When this utility model is used, the first hoop body and the second hoop body piece together cross section so that top margin is aligned with each other by side plate
For the hoop body pair of " mouth " font, during split, each first engaging piece and second engaging piece are in the way of the embedded breach of projection
Intermesh, preforming main cable strand is inserted in into the secondary interior intracavity of hoop body during split, so that the rectangle of preforming main cable strand is horizontal
Section keeps constant, and operations for forming is very convenient；The each section of circular arc in card face is made to block at preforming main cable strand outer rim simultaneously
Each steel wire, is effectively prevented the steel wire dislocation of preforming main cable strand, makes the cross section of preforming main cable strand keep stable.
The beneficial effects of the utility model are：Simple structure, easy to use, strand section is stable, improves main cable strand
Quality, is easy to site operation, saves the construction period, remarkable in economical benefits.
