Abstract
The utility model discloses a prestressed steel strand perforation leading device, which comprises a leading head and a hollow connecting pipe connected with the leading head, wherein the leading head comprises a head part and a bolt part which are manufactured integrally; the bolt part and the hollow connecting pipe are connected; and the head part adopts a streamlined cone structure. The leading device provided by the utility model provides convenience for the construction method of mechanical perforation and has the characteristics of simplicity in manufacturing, low cost and good using effect.
Description
Technical field
The utility model relates to a kind of prestress wire lashing down-lead device.
Background technology
In the design of bridge superstructure, gauge, the arrangement of reinforcement that can reduce the beam body owing to prestressed concrete Cast-in-Situ Continuous Beam structure are few, economical rationality at present; The monobloc cast girder stability is good, line style is consistent, aesthetic in appearance, has bigger economic benefit and social benefit, is therefore extensively adopted.
But to the construction of large-span prestressed continuous box girder, the length of prestress wire is big, and the traditional hand lashing exists speed slow, and construction quality is not high, and particularly super-length prestressed lashing is the thing of comparison difficulty always.
The utility model content
The purpose of the utility model is to provide a kind of prestress wire lashing down-lead device, and the exploitation of the down-lead device of the utility model for the job practices of mechanical lashing has been brought facility, and has manufacturing simply, and is with low cost, the characteristics that result of use is good.
In order to achieve the above object, the technical scheme of the utility model is:
A kind of prestress wire lashing down-lead device comprises lead riser and the hollow tube connector that links to each other with lead riser, and wherein said lead riser comprises head and the bolt part that the one manufacturing forms; Described bolt part links to each other with the hollow tube connector; Described head is the streamlined cone structure, and resistance is little, the destruction to the steel strand bellows that possibly cause in having avoided advancing.
Described bolt part links to each other with the hollow tube connector.
Described bolt part and hollow tube connector are movably connected.
Described bolt part and hollow tube connector are movably connected through the internal thread on external screw thread on the bolt part and the hollow tube connector internal face.
The beneficial effect of the utility model is: the exploitation of the down-lead device of the utility model, for the job practices of mechanical lashing has been brought facility, and have manufacturing simply, and with low cost, the characteristics that result of use is good.

Fig. 1 is the structural representation of the utility model.
The specific embodiment
Embodiment 1
As shown in Figure 1; A kind of prestress wire lashing of present embodiment down-lead device; Comprise lead riser 1 and the hollow tube connector 2 that links to each other with lead riser 1, wherein said lead riser 1 comprises the head 11 and bolt part 12 that the one manufacturing forms, and described bolt part 12 links to each other with hollow tube connector 2.Described bolt part 12 is movably connected through the internal thread on external screw thread on the bolt part 12 and hollow tube connector 2 internal faces with hollow tube connector 2.Described head 11 is the streamlined cone structure, and resistance is little, the destruction to the steel strand bellows that possibly cause in having avoided advancing; Performance is more superior, the effect of better effects if.Start the machine that pushes away that squeezes during construction, the other end of described hollow tube connector can insert steel strand and be connected with steel strand through pipe embedding extruding.Concrete operation method inserts the steel strand end to use behind about 30mm in the hollow tube connector 2 then and manages the embedding clamping for the about 50cm of side direction in earlier the end of steel strand being extruded into from the outside of squeezing the machine that pushes away.Steel strand are with after down-lead device is connected, and push away between machine and the case joist steel twisted wire corrugated tube end in the case beam bellows that pushes prestress wire after entangling steel strand with steel pipe and carry out lashing squeezing.Because the lead riser 1 on the down-lead device has head 11, bellows can not worn out and the quality that guarantees to construct and the speed of construction.The exploitation of the down-lead device of this instance for the job practices of mechanical lashing has been brought facility, and has manufacturing simply, and is with low cost, the characteristics that result of use is good.
