Abstract
The utility model aims to provide a connection structure for the external protecting tube of a stay cable used for a stay cable bridge, which is served as the interconnecting of the external protecting tube with different tube diameters. The technical proposal of the utility model is adopted as follows: a connection structure for the external protecting tube of the stay cable used for the stay cable bridge comprises an external protecting tube with large diameter, an external protecting tube with small diameter and a connecting sleeve for connecting the two external protecting tubes. The outer diameter and the wall thickness of one end of the connecting sleeve are same with that of the external protecting tube with large diameter, and the outer diameter and the wall thickness of the other end are same with that of the external protecting tube with small diameter. The utility model thickens the intelligent cable and the external protecting tube at the joint of steel strands, avoids the entire enlarging of the diameter of the external protecting tube with high-density polyethylene for the entire cable and saves the relevant cost. By adopting the connecting sleeve on the external protecting tube with high-density polyethylene in different diameters to transit and carrying out the finish machining on the transition at factory, the utility model can ensure not only the inherent quality and the appearance quality of the high-density polyethylene pipe, and but also no damage on the intelligent cable.
Description
Technical field
The utility model relates to the outer pillar syndeton of suspension cable of suspension cable bridge, relates in particular to a kind of syndeton that the outer pillar of different tube diameters can be linked together.
Background technology
Need to install many suspension cables on the suspension cable bridge in order to support bridge, in order to make suspension cable durable in use, avoid by air and rainwater corrosion, pillar outside need on suspension cable, installing, the material of outer pillar adopts the good high density polyethylene (HDPE) of chemical property (High Density Polyethylene is called for short HDPE) usually.The outer pillar of the suspension cable HDPE of present domestic use only adopts pillar outside the HDPE of same diameter on same skew cables.But because of needing the health condition of suspension cable is monitored after some suspension cable bridge completion, need in some suspension cable, smart stay cable be installed, smart stay cable only need be arranged in the partial-length of this suspension cable, but because of smart stay cable needs larger-diameter outer pillar, if, then can cause waste so the outer pillar of this suspension cable all adopts the outer pillar of same diameter.In order to reduce expenses, usually only the bigger outer pillar of diameter is adopted at the position that has smart stay cable on the suspension cable, and at other position of suspension cable less outer pillar of diameter still commonly used.Thereby need the outer pillar of different tube diameters be docked.
The utility model content
The purpose of this utility model provides a kind of outer pillar syndeton of suspension cable of suspension cable bridge, docks in order to the outer pillar to different tube diameters.
The technical solution of the utility model: the outer pillar syndeton of a kind of suspension cable of suspension cable bridge, comprise the outer pillar of major diameter, the outer pillar of minor diameter with in order to be connected the adapter sleeve of above-mentioned two outer pillars, the external diameter and the wall thickness thereof of the outer pillar of the external diameter of described adapter sleeve one end and wall thickness thereof and major diameter equate that the external diameter and the wall thickness thereof of the outer pillar of the external diameter of the other end and wall thickness thereof and major diameter equate.
The beneficial effects of the utility model: adopt the method for attachment of the local overstriking of smart stay cable, avoided the outer pillar caliber of high density polyethylene (HDPE) of whole rope all to strengthen, saved expense.Adopt the mode of adapter sleeve to carry out transition to the outer pillar of the high density polyethylene (HDPE) of different tube diameters, and fine finishining is carried out in transition, not only guaranteed the inherent quality of high density polyethylene pipe and presentation quality but also guaranteed that smart stay cable is not damaged in factory.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing A of the utility model adapter sleeve and outer pillar junction;
Description of reference numerals: adapter sleeve 1, smooth transition face 11, local bulge 12, the outer pillar 2 of minor diameter, the outer pillar 3 of major diameter, protective cover 4, pre-pipe laying 5.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
As shown in Figure 1, according to the design length of smart stay cable and the size of physical dimension, the length of determining the outer pillar 3 (external diameter is φ 260mm) of major diameter is 12 meters, adopt adapter sleeve 1 to connect with being connected of the outer pillar 2 (external diameter is φ 235mm) of minor diameter, adapter sleeve is good in factory process before using, and connects at the construction field (site).The external diameter and the wall thickness thereof of the outer pillar 3 of the external diameter of adapter sleeve 1 one ends and wall thickness thereof and major diameter equate that the external diameter and the wall thickness thereof of the outer pillar 2 of the external diameter of the other end and wall thickness thereof and minor diameter equate.
For outward appearance that guarantees the junction and the stress that reduces the junction, also has smooth transition face 11 at the axial position of adapter sleeve 1 near pillar 2 outside little.
Claims (4)
1. the outer pillar syndeton of the suspension cable of a suspension cable bridge, comprise big outer pillar (3), little outer pillar (2) and adapter sleeve (1) in order to be connected above-mentioned two outer pillars, it is characterized in that, the external diameter of the external diameter of described adapter sleeve (1) one end and wall thickness thereof and big outer pillar (3) and wall thickness thereof equate that the external diameter of the external diameter of the other end and wall thickness thereof and little outer pillar (2) and wall thickness thereof equate.
2. the outer pillar syndeton of the suspension cable of suspension cable bridge according to claim 1 is characterized in that the position of the axially close little outer pillar (2) of described adapter sleeve (1) has smooth transition face (11).
