Abstract
The utility model relates to a kind of simple type compression sleeve of finished product prestressing tendon, is fixed with tow lug at one end inwall of compression sleeve, and the inwall one uniform intervals of described compression sleeve is shaped with multiple hangnail bulge loop.The upper plane of described hangnail bulge loop and its axis being parallel, with its axes normal before this hangnail bulge loop, the angle α formed after this hangnail bulge loop and between its axis is acute angle.This compression sleeve structure is simple, easy for installation, lightweight, cost is low, and the hangnail bulge loop be shaped with by its inwall improves the bond stress in distraction procedure between compression sleeve and steel strand; This compression sleeve adopts radial compression, and gripping effect is good, effectively ensure that steel wire bundle there will not be loose phenomenon in threading procedure; Tow lug is welded on the inwall of compression sleeve, and structure is simple, be easy to make.
Description
Technical field
The utility model belongs to the realm of building construction, relates to finished product prestressing tendon, especially a kind of simple type compression sleeve of finished product prestressing tendon.
Background technology
In building and road and bridge building operations, need, by many prestress steel twist wire arranging bunchys (having another name called finished product prestressing tendon), to penetrate in the prestressed pore passage and bellows duct prepared.When finished steel strand bundle is worn and is sent in corrugated conduit, need to withhold a compression sleeve in finished steel strand bundle front end, drawn by device traction compression sleeve, thus be installed on smoothly by steel wire bundle in bellows duct, this mode effectively can improve efficiency of construction.
Through retrieval, find one section of patent document relevant to this patent content, publication number is the Chinese patent of CN203487459U, and this patent discloses a kind of hoop of finished steel strand bundle, and described hoop is a hollow cylinder-shaped sleeve; Described hoop is equipped with to be enclosed within combs the end of compiling the finished steel strand bundle made in order by multiple single steel strand; After dedicated extruded equipment extruding hoop, the cylindrical of hoop forms axial technique impression.
By contrast, in above-mentioned patent publication us, there are the following problems:
The inwall of hoop is smooth structure, and this structure makes the bond stress of hoop and steel wire bundle little, and in the process of traction, steel wire bundle exists the problem of deviating from.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of structure is simple, guidance quality is strong, improves the simple type compression sleeve of the finished product prestressing tendon of bond stress.
Scheme of the present utility model is achieved in that
A simple type compression sleeve for finished product prestressing tendon, is fixed with tow lug at one end inwall of compression sleeve, and the inwall one uniform intervals of described compression sleeve is shaped with multiple hangnail bulge loop.
And the upper plane of described hangnail bulge loop and its axis being parallel, with its axes normal before this hangnail bulge loop, the angle α formed after this hangnail bulge loop and between its axis is acute angle.
And this compression sleeve is by forcing press extruding banding on steel wire bundle, and the external surface of this compression sleeve is shaped with axial technique impression, this axial technique impression axially forms strip indentation along compression sleeve.
Advantage of the present utility model and good effect are:
This compression sleeve structure is simple, easy for installation, lightweight, cost is low, and the hangnail bulge loop be shaped with by its inwall improves the bond stress in distraction procedure between compression sleeve and steel strand; This compression sleeve adopts radial compression, and gripping effect is good, effectively ensure that steel wire bundle there will not be loose phenomenon in threading procedure; Tow lug is welded on the inwall of compression sleeve, and structure is simple, be easy to make.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is the I portion enlarged drawing of Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail.
A kind of simple type compression sleeve of finished product prestressing tendon, as shown in Figure 1 and Figure 2, tow lug 3 is welded with at one end inwall of compression sleeve 1, the inwall one uniform intervals of described compression sleeve is shaped with multiple hangnail bulge loop 4, the effect of this hangnail bulge loop to improve the bond stress in distraction procedure between compression sleeve and steel strand, prevents steel strand in the process of traction from deviating from.
In the present embodiment, the structure of described hangnail bulge loop as shown in Figure 3, the upper plane of this hangnail bulge loop 6 and its axis being parallel, this hangnail bulge loop before 7 with its axes normal, the angle α formed between 5 and its axis after this hangnail bulge loop is acute angle.
This compression sleeve on steel wire bundle, is shaped with axial technique impression 2 at the linkage section external surface of compression sleeve by forcing press extruding banding, and this axial technique impression axially forms strip indentation along compression sleeve.
The manufacturing process of this steel wire bundle is:
One end suit compression sleeve of traction is needed at steel wire bundle, with extrusion equipment, pressure is applied to the outer rim of compression sleeve, make compression sleeve inwall axially on length direction banding be wrapped on the outer single steel strand outer margin contour of steel wire bundle, compression sleeve and steel strand are firmly gathered and are integrated.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in detailed description of the invention; every other embodiments drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
