Abstract
The utility mode relates to an expansion taper anchorage device, which mainly comprises a ring shaped bushing (1) and a cone bushing (2), and is characterized in that the ring shaped bushing is a round cylinder, a round hole (3) of a same upper and lower diameter is arranged in the central, and the hole wall of which is smooth; and a cone bushing separated with the ring shaped bushing is arranged as a cone, a round hole (3) of a same upper and lower diameter is arranged in the central, and the inner and outer hole wall of which is smooth, the diameter of the round terminal surface (5) at the bottom of the cone of the cone bushing is 2 to 10mm smaller than the one of the inner hole of the ring shaped bushing. The utility model can be applied to the fix of the terminal of the steel stranded wire, and which is of the characteristics of a simple structure, an easy production, a low cost and a flexible use.
Description
Technical field
The utility model belongs to a kind of steel strand prestress technology, and concrete is a kind of bloated awl ground tackle.
Background technology
Steel strand are used very extensive in construction work, and the termination of steel strand fixedly is an important problems.For a long time, people have proposed much to be used to solve the fixing method in steel strand termination, have designed the ground tackle of multiple structure.These all have certain practical value, and that uses on engineering is also a lot.But there are some shortcomings in existing ground tackle, such as, a lot of ground tackles have more corner angle, in use easily scuffing are caused in the anchorage zone of steel strand, have damaged its intensity; The ground tackle structure that also has is comparatively complicated, processes inconvenience, has improved cost of production; The member that also has is more use convenient inadequately etc.Therefore, need proposition a kind of simple in structure, easy to manufacture, cost is low, and is easy to use, and the high ground tackle of the firmness of anchoring.
The utility model content
The purpose of this utility model is at the problems referred to above, proposes a kind of bloated awl ground tackle, to avoid the problems referred to above, also have simple in structure, easy operating, practical value is big, saves material, cost is low, anchoring effect is good, the advantage of being convenient to promote the use of.
The purpose of this utility model is achieved through the following technical solutions: a kind of bloated awl ground tackle, mainly comprise: ring sleeve, taper bushing, it is characterized in that: described ring sleeve is a right cylinder, and the centre is provided with an identical circular hole of diameter up and down, and hole wall is smooth; Be provided with a taper bushing that separates with ring sleeve in addition, this taper bushing is cone shape, the centre is provided with an identical circular hole of diameter up and down, and internal and external walls is smooth, and the cone base nose circle face diameter of this taper bushing is less than the diameter of bore 2-10mm of ring sleeve.
Described taper bushing can also be provided with cracking of vertically connecting, so that the center line of steel strand penetrates and better holds tightly.
The utility model is owing to adopted right cylinder, diameter is identical up and down for interior circular hole, the structure that inner hole wall is smooth, and taper bushing also is the smooth structure of inside and outside wall, so make easily, cost is low, and the fixed position to steel strand can not produce damage in use, and the steel strand termination is evenly distributed, and is fastening effective, particularly simple to operate, convenient, flexible.Therefore, the utlity model has simple in structure, easy to use flexibly, cost is low, fastening effective advantage.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further: embodiment 1: referring to accompanying drawing, a kind of bloated awl ground tackle mainly comprises: ring sleeve 1, taper bushing 2, and described ring sleeve is a right cylinder, the centre is provided with an identical circular hole 3 of diameter up and down, and hole wall is smooth; Be provided with a taper bushing that separates with ring sleeve 2 in addition, this taper bushing is cone shape, the centre is provided with an identical circular hole 4 of diameter up and down, and internal and external walls is smooth, and cone base nose circle face 5 diameters of this taper bushing are less than the diameter of bore 2-10mm of ring sleeve.
Embodiment 2: a kind of bloated awl ground tackle, described taper bushing be provided with one vertically connect crack 6, other structures are identical with embodiment 1, repeat no more.
The utility model inserts ring sleeve with the termination of steel strand in use, and the termination of steel strand is stretched out from the hole of ring sleeve, and taper bushing from the center line termination that a thin end is inserted in steel strand, is return tension with the steel strand termination then and got final product.
Claims (2)
1, a kind of bloated awl ground tackle mainly comprises: ring sleeve (1), taper bushing (2), and it is characterized in that: described ring sleeve is a right cylinder, and the centre is provided with an identical circular hole (3) of diameter up and down, and hole wall is smooth; Be provided with a taper bushing that separates with ring sleeve in addition, this taper bushing is cone shape, the centre is provided with an identical circular hole (4) of diameter up and down, and internal and external walls is smooth, and cone base nose circle face (5) diameter of this taper bushing is less than the diameter of bore 2-10mm of ring sleeve.
2, bloated awl ground tackle according to claim 1 is characterized in that: described taper bushing is provided with one crack (6) that vertically connect.
