Abstract
The utility model discloses a kind of integrally dragging fixtures, including drawing head, closing sleeve, draught line and limiting plate；Draught line is located at the center of steel strand wires, is surrounded by steel strand wires, and drawing head is extended to, and drawing head is located at one end of draught line, and detachable be fixedly connected is formed with draught line；Closing sleeve is located at the periphery of steel strand wires, and draught line and steel strand wires run through closing sleeve, fitted closely with closing sleeve；Limiting plate is located at the side of closing sleeve, with draught line and steel strand wires match.A kind of integrally dragging fixture provided by the utility model, steel strand wires are clamped with closing sleeve using draught line, draught line is connected by drawing intermediate plate, under being acted on due to taper in traction, microcephaly tenses draught line, steel strand wires are clamped by frictional force in closing sleeve, follow movement, can primary radial tethered sliding, improve propulsive efficiency, no longer human weld is needed to fix, reduces construction cost.
Description
Technical field
The utility model is related to a kind of connection end more particularly to a kind of integrally dragging fixtures.
Background technology
During prestressed reinforced concrete Construction of Continuous Box Beam, for prestressed pore passage by prefabricated pore-forming, steel strand wires are big
Mostly use the construction method of rear lashing.The elongated beam steel strand wires radical of prestressed strand has 12,15 and 17 etc., steel strand wires root
Number is relatively more, and length generally has more than 100 meters.After the completion of box beam concrete pours, duct space itself is limited, along with through mixed
Solidifying soil pours extruding of vibrating, and duct easily deforms.Using the method for single lashing, last two steel strand wires of steel beam can be caused
It is difficult to cause anti-work by duct and delay work.
Conventional way is that one end of every beam steel strand wires is connected into taper entirety by root bead using the method for electric welding, then with leading
Messenger is integrally pulled through duct.After the completion, then by this section of quenched steel strand wires of this welding it cuts off.This method not only take but also
Damage material, influences construction speed and cost.
Utility model content
The utility model is intended to provide a kind of integrally dragging fixture, is carried out to steel strand wires by closing sleeve and limiting plate whole
It closes and fixes, recycle a draught line to draw entire steel wire bundle, ensure drawing using the taper of closing sleeve
Steel strand wires mutually squeeze tension in journey, improve propulsive efficiency, reduce construction cost.
To solve the above problems, a kind of integrally dragging fixture provided by the utility model uses following technical solution：
A kind of integrally dragging fixture, including drawing head, closing sleeve, draught line and limiting plate；The draught line is located at
The center of steel strand wires, is surrounded by steel strand wires, extends to the drawing head, and the drawing head is located at the one of the draught line
End, detachable be fixedly connected is formed with the draught line；The closing sleeve is located at the periphery of steel strand wires, described
Draught line and steel strand wires run through the closing sleeve, are fitted closely with the closing sleeve；The limiting plate is located at institute
The side for the closing sleeve stated, with draught line and steel strand wires match.
Further, the drawing head is internally provided with traction intermediate plate, the traction intermediate plate and the traction
Line is inconsistent, while forming detachable be fixedly connected with the drawing head.
Further, the traction intermediate plate is set as tapered profile, and the microcephaly of the traction intermediate plate leads with described
Lead is inconsistent.
Further, the closing sleeve is set as tapered profile, and microcephaly is located at close to the side of the drawing head,
It is internal inconsistent with steel strand wires.
Further, tool clamping piece is provided on the draught line, the tool clamping piece is located at the draught line
On, while between the limiting plate and closing sleeve, being in contact with the draught line.
The beneficial effects of the utility model are：A kind of integrally dragging fixture provided by the utility model, utilizes draught line
Steel strand wires are clamped with closing sleeve, connect draught line by drawing intermediate plate, under being acted on due to taper in traction, microcephaly tenses
Draught line, steel strand wires are clamped by frictional force in closing sleeve, and movement is followed, can primary radial tethered sliding, improve
Propulsive efficiency, it is no longer necessary to which human weld fixes, and reduces construction cost.

First 1, the drawing head 1 is located at one end of the draught line 3, and detachable fixed company is formed with the draught line 3
It connects；The closing sleeve 2 is located at the periphery of steel strand wires, and the draught line 3 and steel strand wires run through the closing sleeve 2,
It is fitted closely with the closing sleeve 2；The limiting plate 4 is located at the side of the closing sleeve 2, with draught line
3 and steel strand wires match.
Further, being internally provided with for the drawing head 1 draws intermediate plate 5, and the traction intermediate plate 5 is led with described
Lead 3 is inconsistent, while forming detachable be fixedly connected with the drawing head 1.
Further, the traction intermediate plate 5 is set as tapered profile, the microcephaly of the traction intermediate plate 5 with it is described
Draught line 3 is inconsistent.
Further, the closing sleeve 2 is set as tapered profile, and microcephaly is located at one close to the drawing head 1
Side, it is internal inconsistent with steel strand wires.
Further, tool clamping piece 6 is provided on the draught line 3, the tool clamping piece 6 is located at the traction
On line 3, while between the limiting plate 4 and closing sleeve 2, being in contact with the draught line 3.
The utility model is not limited to above-mentioned specific embodiment, and those skilled in the art visualize from above-mentioned
Hair, without performing creative labour, made various transformation are all fallen within the scope of protection of the utility model.
