Description
Technical field
The present invention relates to a kind of constructing devices and its construction method of technical field of building construction, particularly a kind of prestressing force
Steel strand integral bundle draft gear and its construction method for prestressing tendon integrally dragging.
Background technology
In building engineering construction, the lashing construction of prestressed pore passage steel strand wires is frequently encountered, especially in wind-power tower
In engineering construction, the lashing construction that section assembling formula concrete air pylon tube construction is related to prestressed pore passage steel strand wires needs to carry out
Prestressing tendon is drawn, and is particularly present substantial amounts of 6 hole and following steel wire bundle prestressed pore passage；Due to wind-power tower coagulation
Native segment is more, causes at the composition surface of long range prestressed pore passage segment that there are faulting of slab ends reduces duct latus rectum, to prestress steel
Strand bundle lashing brings difficulty；At present, the whole beam draft gear outer diameter in general construction means is both greater than steel wire bundle minimum
Circumscribed circle diameter can pass through more difficult at prestressed pore passage concrete segment composition surface to steel wire bundle.
The content of the invention
It is an object of the invention to：There is provided a kind of prestress wire whole beam draft gear, the whole beam of the prestress wire
Draft gear outer diameter is not more than steel wire bundle minimum circumscribed circle diameter, overcomes general draft gear outer diameter more than steel wire bundle most
Small circumscribed circle diameter to steel wire bundle whole strand pricking it is more difficult the shortcomings that, invention also provides the prestress wire is whole
Beam draft gear is used for the construction method of steel wire bundle integrally dragging, to solve the above problem existing for prior art.
The technical solution to solve the above problems is：A kind of prestressing tendon integrally dragging device, it is characterised in that：Bag
Include positioning seat and drawing head；
The positioning seat is a circle tube member, the outer diameter of the circle tube member it is equal with steel wire bundle minimum circumscribed circle diameter or
Smaller, to set female thread segment, the side of the circle tube member other end is evenly distributed with n items for one end for circle tube member one end
The central hair of heading by groove；
It with externally threaded cylindrical segment, the other end is to connect for what is be connected with rotary connector that one end of the drawing head, which is,
Head, maximum outside diameter are consistent or smaller with positioning seat outer diameter；
Under use state, each groove that each steel strand wires of prestressing tendon heading are each passed through positioning seat is installed on positioning
Seat precalculated position, the externally threaded cylindrical segment of drawing head band is screwed with the thread segment of positioning seat to be coupled, another termination of drawing head
Head is connected with rotary connector one end connector I of dimension, and rotary connector other end connector II is dynamic with being connected traction
The steel wire rope of power apparatus is connected；The value range of above-mentioned n is：The integer of 2≤n≤6.
Relevant another technical solution is：A kind of prestressing tendon integrally dragging construction method, it is using this hair
Bright above-mentioned prestressing tendon integrally dragging device realizes the construction method to prestressing tendon integrally dragging, it is wrapped
Include following steps：
A, prestressing tendon pre-processes：
Each steel strand wires front end of the steel wire bundle of advance lower honest material is subjected to side silk stripping and cuts off certain length, leaves center
Silk, and heading is carried out to central hair；
B, prestressed steel wire bundle integrally dragging device：
B1, by after pretreatment each steel strand wires of the heading of prestressing tendon be each passed through each groove of positioning seat
It is installed on positioning seat precalculated position；
B2, the externally threaded cylindrical segment of drawing head band with positioning seat thread segment is screwed it is coupled, another end connector of drawing head and phase
Rotary connector one end of specification is answered to be connected, the rotary connector other end is connected with being connected the steel wire rope of hauling power device；
C, prestressing tendon integrally dragging：
Start hauling power device, steel wire bundle is drawn into corresponding prestressed pore passage, the entirety for completing steel wire bundle is worn
Beam.
Due to taking said structure, the present invention's《The whole beam draft gear of a kind of prestress wire and its for steel strand wires
The construction method of beam integrally dragging》It has the advantages that：
1st, since the outer diameter of the whole beam draft gear of prestress wire of the present invention can be accomplished to be less than steel wire bundle minimum circumscribed circle
Diameter overcomes and increases because draft gear outer diameter is more than steel wire bundle minimum circumscribed circle diameter to prestressing tendon whole strand pricking
The shortcomings that adding difficulty.So as to be substantially reduced the whole beam traction of prestressing tendon in similar concrete segment pin-connected panel wind-power tower
Difficulty.
2nd, using heading mode of traction, safety between the whole beam draft gear of the prestress wire of the present invention and steel wire bundle
Reliability is high, and ancillary equipment is few, and simple to operation.
3rd, construction method is easy：Lead between the positioning seat and drawing head of the whole beam draft gear of prestress wire of the present invention
Threaded connection is crossed, connection is reliable, convenient disassembly, greatly speeds up construction speed.
By it was verified that the whole beam draft gear of prestress wire of the present invention and its for steel wire bundle integrally dragging
Construction method effectively solves the difficulty of the whole beam traction of prestressing tendon in section assembling formula concrete wind-power tower engineering
Topic, and construction efficiency is high, has higher economy and practice significance.
With reference to the accompanying drawings and examples to the present invention's《The whole beam draft gear of a kind of prestress wire and its for steel
The construction method of strand bundle integrally dragging》Technical characteristic be described further.
