Description
Technical field
The present invention relates to technical field of bridge engineering, specially a kind of steel strand stay cable repairing workpiece.
Background technology
The suspension cable of traditional cable-stayed bridge uses galvanizing soap-free emulsion polymeization PE sheath steel strand wires mostly, is in the plating of the surface of steel strand wires
Zinc, steel strand gap perfusion grease, outsourcing PE sheaths form finished steel twisted wire.As shown in figure 1, PE sheaths (1) are in long-term use
During, easily the defects of generation crack, broken hole (2), way of the prior art is：One PE pipe (3) of processing in addition, the PE
It is in two halves on tubular construction, its point half is deposited at the defective PE sheaths of tool, finally by the seam of the PE pipe two halves of repairing
Locate bonding, this method difficulty of construction is big, maintenance conditions are inconvenient and the anti-corrosion time limit is short, because the PE pipes of repairing up
Easily defect is produced again.
It is also a kind of for the needs of the factors such as attractive in appearance and anticollision in existing engineering, in a part of steel strand stay cable
A stainless steel pipe sleeve (4) is arranged on former PE sheaths, as shown in Fig. 2 in the seam crossing of PE sheaths and stainless steel pipe sleeve, with sealing
Glue seals.The defects of this structure, has：1st, the fluid sealant anti-corrosion time limit is limited, and rainwater penetrates into the gap of PE sheaths and stainless steel pipe sleeve
In, if defective on PE sheaths, rainwater will be penetrated into internal steel strand wires, corrosion steel strand wires；2nd, except being arranged with stainless steel
Defect is produced at other PE sheaths outside set needs inconvenience of being constructed during repairing, and the method for repairing and mending of such case prior art is：Separately
PE pipe (30) of the outer processing one with gap, the PE pipes with gap are to process to form a stepped gap in the lower end of PE pipes,
It is in two halves in the PE pipe overall structures, its point half is deposited at the defective PE sheaths of tool, finally by the PE pipes two of repairing
Half seam crossing is bonding, the difficult processing of the lower end gap of PE pipes in this method, and overall reparation construction difficulty is big, maintenance conditions
The inconvenient and anti-corrosion time limit is short, because the PE pipes of repairing up also easily produce defect again.
The content of the invention
Steel strand stay cable repairing workpiece is carried out using stainless steel tube it is an object of the invention to provide one kind, solved existing
The technical problem that difficulty of construction existing for method for repairing and mending is big in technology, maintenance conditions are inconvenient and the anti-corrosion time limit is short etc..
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of steel strand stay cable repairing workpiece, the workpiece is stainless steel tube, and the stainless-steel pipe is included radially
Symmetrical two parts, two parts stainless-steel pipe is stitched together during use, the incision position of two parts stainless-steel pipe is set
There is the connecting plate for two parts stainless-steel pipe to be stitched together.
Further, in order to connect into entirety with the stainless steel pipe sleeve in existing engineering, the bottom of stainless steel tube offers
Stairstepping gap, stairstepping gap can be overlapped in existing stainless steel tube and put.
Preferably, when the workpiece is used to repair steel strand stay cable, workpiece is sheathed on the defective steel strand wires oblique pull of tool
Suo Shang, and the internal diameter of workpiece 4-8mm big compared with the external diameter of steel strand stay cable, interstitital texture glue is needed in the space.Structure glue
Composition is prior art.
Preferably, the internal diameter of workpiece 4mm big compared with the external diameter of steel strand stay cable, the gap ensure that the structure glue of filling will not
Rust steel pipe is bonded on the PE pipes of steel strand stay cable.
Preferably, two parts stainless-steel pipe is bolted at connecting plate, convenient to need to remove in the future, can also
Using permanent connection modes such as welding.
The present invention uses above-mentioned technical proposal, has effect as is evident below：
It is of the present invention repairing workpiece it is simple in construction, handling ease, and with the workpiece repairing steel strand stay cable when, apply
Work difficulty is small, and subsequent maintenance is detected and provides convenient, and structure glue is non-aging, anti-corrosion year limit for length.
