Description
Technical field
The utility model belongs to the realm of building construction, relates to finished product prestressing tendon, especially a kind of novel rings for 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 CN203808529U, which disclose a kind of prestress wire lashing guiding string bag, comprise tow lug and netting, described tow lug and netting are the braiding of multistrand rope and doubling and the all-in-one-piece string bag, its doubling position is head, form the tow lug of tension, the cover below of described tow lug has the steel bushing of a fastening netting, and the part after steel bushing breaks up braiding and the netting of open rearward end.
By contrast, there are the following problems for the tow lug in above-mentioned patent publication us:
1, tow lug is packed on steel bushing, in the process of install tow lug and hoist engine, because steel strand itself exist torsion, tow lug is caused to drive steel wire bundle together to rotate (namely servo-actuated), now increase the frictional force between steel strand outer rim and bellows, reduce efficiency of construction.
2, traditional tow lug can not be reused, and causes great waste.
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, reusable, the novel rings for finished product prestressing tendon of convenient and flexible installation.
Scheme of the present utility model is achieved in that
A kind of novel rings for finished product prestressing tendon, comprise suspension ring body and interior six side's connecting bolts, the bottom concentric gap of described suspension ring is coated with connecting bolt, described in this, suspension ring body is provided with dismountable wrench assembly, this wrench assembly comprises junction plate, hexagon prism and spring, upper surface, described junction plate one end is fixedly mounted with the hexagon prism for the bolt that is rotatably connected vertically arranged, and this hexagon prism profile is corresponding with described connecting bolt;
Described junction plate the other end is integrally shaped with symmetrically arranged linking arm, and the end of these two linking arms in opposite directions one symmetry is shaped with two connecting portions, is connected with spring between these two connecting portions;
Clamp an opening steel ring in the annular groove that the top of described hexagon prism is coaxially shaped with, the diameter of this opening steel ring is greater than the diameter of hexagon prism.
And the bottom of described suspension ring body is coaxially shaped with annular boss, is provided with packing ring between the upper surface of this annular boss and the nut of connecting bolt.
And, in the annular groove that described suspension ring body bottom portion is shaped with, gasket ring is installed.
Advantage of the present utility model and good effect are:
1, the suspension ring body about axis of these suspension ring can 360 degree of rotations, avoid the phenomenon that steel strand are servo-actuated, effectively improve operating efficiency; After steel wire bundle is penetrated bellows, connecting bolt can be taken out, realize recycling, effectively reduce construction cost.
2, these suspension ring body installs dismountable wrench assembly, dismounting suspension ring are convenient and swift, and wrench assembly is not easily lost, flexible and convenient to use.
Construction opening steel ring on the hexagon prism of 3, these suspension ring, effectively can make up the gap between hexagon prism and connecting bolt, prevent hexagon prism from skidding, improve operating efficiency.
4, the utility model structure is simple, design science is reasonable, convenient to operation, not only improve efficiency of construction, and can repeat recycling, effectively reduce costs.

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 novel rings for finished product prestressing tendon, as shown in Figure 1, comprise suspension ring body 1, wrench assembly 2 and interior six side's connecting bolts 3, the bottom concentric gap of described suspension ring is coated with connecting bolt, and this suspension ring body is also provided with dismountable wrench assembly.
In the present embodiment, the structure of described connecting bolt and suspension ring body as shown in Figure 2 and Figure 3, the bottom of this suspension ring body is coaxially shaped with annular boss 5, packing ring 4 is installed between the upper surface of this annular boss and the nut of connecting bolt, in the annular groove that this suspension ring body bottom portion is shaped with, gasket ring 6 is installed.
The structure of described wrench assembly is as Fig. 4, Fig. 5, shown in Fig. 6, comprise junction plate 9, hexagon prism 7 and spring 10, upper surface, described junction plate one end is fixedly mounted with the hexagon prism for the bolt that is rotatably connected vertically arranged, this hexagon prism profile is corresponding with described connecting bolt, an opening steel ring 8 is clamped in the annular groove that the top of this hexagon prism is coaxially shaped with, the diameter of this opening steel ring is slightly larger than the diameter of hexagon prism, the effect of opening steel ring makes up the gap between hexagon prism and connecting bolt nut, prevent the hexagon prism when being rotatably connected bolt from skidding, improve construction working efficiency,
