Abstract
The invention discloses a kind of Split pin direct type cable cord clip, including one piece of upper half Rope holder body, one piece of hoist cable Rope holder bodies and two pieces of lower half banding Rope holder bodies with otic placode；Lower half banding Rope holder body is located at the two sides of hoist cable Rope holder body；Total axial length of hoist cable Rope holder body and two pieces of lower half banding Rope holder bodies is equal to the axial length of upper half Rope holder body；Hoist cable Rope holder body and lower half banding Rope holder body have coherent chimeric tongue and groove, and upper half Rope holder body is also equipped with chimeric tongue and groove engaged therewith；Cord clip hole is formed after upper half Rope holder body is chimeric with the tongue and groove of hoist cable Rope holder body and lower half banding Rope holder body on cross section, and is connected using bolt pair.Split type pin joint rope clip provided by the invention can increase the friction resistance to sliding power of cord clip.In addition, split type pin joint rope clip is also equipped with cost economic, install convenient, does not increase the advantages that being tightened cable secondary stress.
Description
Technical field
The invention belongs to bridge suspension cables, the prestressed cable fixture design field of building prestressing force string branch structure, specifically
It is related to a kind of split type pin joint rope clip.Cord clip includes upper half Rope holder body, hoist cable Rope holder body and lower half banding Rope holder body, Neng Gouti
The reliability of high cord clip antiskid connection.
Background technique
Bridge suspension cable, the prestressed cable for building prestressing force string branch structure are needed by the fixture specially designed in local position
It sets and is fastened, while fixture also needs reliably to be connect with Force transmission parts hoist cable, to guarantee stable structure.Pin joint type rope
Folder is saved casting cost and is widely used, be detailed in " Cable because moulding is simple, good to the applicability that cable is linear
Supported bridges concept and design " (this pungent work of J. Jim of Neil).But traditional pin joint rope clip,
Under the pulling force effect of the hoist cable or prestressed cable that are connected with cord clip, the hoist cable Rope holder body of direct tension can occur mutually to strain
Shape leads to the trend come to nothing relative to the suspension cable or prestressed cable surface that are tightened, reduces cord clip fastening force, and then reduce
The friction resistance to sliding power of cord clip to cord clip and is tightened being reliably connected between cable member and adversely affects, and it is sliding to increase cord clip
Move risk.It is detailed in paper " the cord clip antiskid limit frictional resistance analysis based on multiple dimensioned model " (" bridge construction " 2016 the 5th
Phase), " vertically tightening bolts type cable parrel mechanical characteristic and design criteria research " (" bridge construction " the 2nd phase in 2008).Mesh
There is the Case Report common occurrence of hoist cable cord clip sliding in suspension bridge in preceding operation, and skidding distance can reach 30mm, give structure
Safety belt carrys out hidden danger, is detailed in " modern bridge maintenance and management " (Chen Weizhen etc. writes).This engineering problem is urgently resolved.
Summary of the invention
Present invention aim to address under hoist cable pulling force effect, cable is with pin joint type fixture due to friction resistance to sliding power reduces
The problem of sliding.
Realize the technical solution of the object of the invention are as follows:
A kind of Split pin direct type cable cord clip, including one piece of upper half Rope holder body, one piece of hoist cable cord clip with otic placode
Body and two pieces of lower half banding Rope holder bodies；Lower half banding Rope holder body is located at the two sides of hoist cable Rope holder body；Under hoist cable Rope holder body and two pieces
Total axial length of half banding Rope holder body is equal to the axial length of upper half Rope holder body；Hoist cable Rope holder body and lower half banding Rope holder body
With coherent chimeric tongue and groove, upper half Rope holder body is also equipped with chimeric tongue and groove engaged therewith；Upper half Rope holder body and hoist cable cord clip
Cord clip hole is formed on cross section after body and the tongue and groove of lower half banding Rope holder body are chimeric, and is connected using bolt pair.
Split type pin joint rope clip provided by the invention can increase the friction resistance to sliding power of cord clip.Lower half banding Rope holder body
After being connect with upper half Rope holder body by prestressed high-strength bolt pair, since lower half banding Rope holder body is separated with hoist cable Rope holder body,
The fastening force of cable will not be reduced because of by hoist cable pulling force effect, friction resistance to sliding power would not also reduce.This
Outside, split type pin joint rope clip is also equipped with cost economic, install convenient, does not increase the advantages that being tightened cable secondary stress.
Detailed description of the invention
Fig. 1 is the three-dimensional figure of Split pin direct type cable cord clip, shows each Rope holder body and prestressed high-strength spiral shell in figure
The assembly relation of bolt pair；
Fig. 2 is Split pin direct type cable cord clip elevation；
Fig. 3 hoist cable Rope holder body separates the drawing of place (at A) with lower half banding Rope holder body.
Wherein, 1- upper half Rope holder body, 2- hoist cable Rope holder body, 3- prestressed high-strength bolt pair, the upstream 4- lower half banding cord clip
Body, the downstream 5- lower half banding Rope holder body, 6- tongue and groove build joint, 7- lower half banding Rope holder body separate seam with hoist cable Rope holder body.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
The basic idea of the invention is that the banding Rope holder body separated with hoist cable Rope holder body, banding Rope holder body are arranged in cord clip
With upper half Rope holder body pairing, to the tightening force of cable will not because hoist cable power act on and reduce, thus can ensure cord clip and
It is reliably connected between cable.
Referring to Fig. 1, the clamp of split type cable cord clip includes one piece of upper half Rope holder body, one piece of hoist cable Rope holder body and two pieces
Lower half banding Rope holder body, the tongue and groove construction on clamp wall meet matching relationship, can form the circular hole of perforation to being combined,
It is connected by prestressed high-strength bolt pair.The axial length of the lower half banding Rope holder bodies of two pieces of identical sizes and hoist cable Rope holder body it
Equal with upper half cord clip axial length, after guaranteeing installing Cable-clamp, hoist cable acts on resultant force line and passes through cord clip center, maximum journey
Degree reduces the secondary stress generated at the port of cord clip upstream and downstream by main push-towing rope bending.Hoist cable Rope holder body has otic placode, the pin on otic placode
Hole and hoist cable rope head pin joint.The axial length of lower half banding Rope holder body and the quantity of installation bolt are according to antiskid bearing capacity (hoist cable
Power) needs be designed, but should ensure that two pieces of banding Rope holder bodies axial length and thereon install bolt quantity it is identical, with
So that the size and distribution to cable tightening force are symmetrical relative to hoist cable resultant force.
It when installation, lifts that each clamp is in place on cable respectively first, double threaded screw is then passed through into matching on cord clip wall
Hole is closed, after tensioning, cooperates spheric washer, is lockked with nut.
