Description
Technical field
The present invention relates to suspension cable mounting structure technical fields, in particular to a kind of installation of overweight parallel steel wire suspension cable
Point structure.
Background technique
Parallel steel wire suspension cable is mainly used in cable-stayed bridge and the super high-rise building field of science of bridge building, with span of bridge
It is continuous increase and depth of building constantly increases, rope length of parallel steel wire suspension cable, Suo Chong, stretching force also constantly break through newly
Record, also proposed completely new requirement to the safety of suspension cable, durability, reliability etc..It is oblique for overweight parallel steel wire
For drag-line, how to ensure during the high-altitude of suspension cable is hung it is safe and reliable be a big technical problem urgently to be resolved.
Currently, conventional parallel steel wire suspension cable, which is hung mainly, suspension centre method and tower crane Method for Installation, wherein suspension centre method is main
Using tower top truss and hoist engine, and it can be divided into that single-point is hung, two o'clock is hung and hung with multiple spot.Single-point is hung, multiple spot is hung and tower crane Method for Installation
It is suitable primarily for that length is shorter, suspension cable of lighter in weight.It is main to be hung using two o'clock for longer, heavier drag-line
Equipment, method, i.e., using dedicated cord clip clamping cable body as interim installation point, then connect with tackling system carry out promoted hang, extension
If after the completion, removing cord clip, such method lifting ability is still limited, is unsatisfactory for overweight (as more than 100t) suspension cable and hangs
It is required that and chucking power it is excessive when, have damage the risk of cable body sheath.
Summary of the invention
The purpose of the present invention is to solve the deficiency of the above background technology, provides a kind of overweight parallel steel wire suspension cable
Point structure is installed.
The technical solution of the present invention is as follows: a kind of installation point structure of overweight parallel steel wire suspension cable, it is characterised in that: including
Rigid enclosure；The circumferential groove of circle exposure steel tendon is offered on the oblique pulling cable body sheath；The rigid enclosure is to be set in
The steel tendon of tubular structure in groove, rigid enclosure and groove connects, the axial ends of rigid enclosure and the sheath of groove two sides
It is tightly connected, the connection structure that the periphery face of rigid enclosure is provided with convenient for gripping.
The further rigid enclosure is by the annular metal component being fixed on steel tendon of casting.
The further rigid enclosure is the annular component being bonded on steel tendon by binder.
The further connection structure includes a plurality of stressed collar being opened on rigid enclosure periphery face, multiple shearings
Ring is arranged along rigid enclosure axially spaced-apart；The stressed collar is the annular slot structure along rigid enclosure radial depressions.
Gasket is provided between the further axial ends of the rigid enclosure and the sheath of groove axial sides；It is described
Gasket is annular seal arrangement of the ring set between rigid enclosure and sheath.
Advantages of the present invention has: 1, by the outside of steel tendon be arranged rigid enclosure, can convenient for entire suspension cable into
Row grips, and lifting is facilitated to carry, a part of rigid enclosure as suspension cable permanent structure, and construction cord clip can be clamped directly
In rigid enclosure, the risk of no suspension cable damage guarantees the integrality of suspension cable sheath, and then ensure that the use longevity of suspension cable
Life；
2, rigid enclosure is fixed on steel tendon by way of casting, installation is extremely convenient, and casting can make rigidity
It covers and is greatly improved with the bonding strength of steel tendon, stability is good；
3, rigid enclosure is bonded on steel tendon by bonding agent, it is easy for installation, improve the installation effectiveness of rigid enclosure；
4, the connective stability of rigid enclosure and cord clip can be increased as the connection structure convenient for clamping by stressed collar,
Connection type is simple；
5, by setting gasket, it is ensured that the connection sealing between rigid enclosure, steel tendon and sheath, prevent gas or
Steam enters in steel tendon and generates corrosiveness to it.
The installation of the configuration of the present invention is simple, rigid enclosure is extremely convenient, improves the stability of cord clip clamping, and will not be to oblique
Drag-line cable body causes any damage, has great promotional value.
