Abstract

The utility model discloses a steel strands bundle threading device which comprises a butting sleeve, a steel wire rope buckling head, a steel strands buckling head, a heading steel strands connecting sleeve and a locking and fixing threaded sleeve, wherein a steel strands outer jacket is sleeved on a plurality of beams of steel strands; a middle steel strand beam penetrates through a heading steel strands connecting sleeve and is subjected to heading operation; the heading steel strands connecting sleeve is clamped into the butting sleeve; steel wire ropes are clamped into the butting sleeve through the steel wire rope buckling head; the locking and fixing threaded sleeve is sleeved on the butting sleeve; a hexagonal nut is screwed on one end of the locking and fixing threaded sleeve, close to the steel wire ropes; and each steel strand beam is clamped into the butting sleeve through the steel strands buckling head. The steel strands bundle threading device is reliable in connection, the steel strands is connected with a traction part in a heading way, and the pulling force-applying way is adopted for replacing the pushing force-applying way; traction is completed at once through a single-hole whole-beam prestressed reinforcing steel; and the steel strands bundle threading device is simple in operation, can be recycled and solves the problems that in the traditional bundle threading method, the single bundle threading is insufficient in capacity and consumes labor and is low in efficiency, etc.

Description

Steel strand penetrating device

Technical field

The utility model relates to post-tensioned construction presstressed reinforcing steel lashing construction equipment, particularly a kind of steel strand penetrating device.

Background technology

The post-tensioned construction prestressed girder is being built completion, implements must in prestress pipe, pass steel strand earlier before the stretch-draw.More for a long time,, cause the lashing difficulty at the steel wire bundle number owing to factors such as the duct are crooked, steel strand weight is big.

Traditional lashing method has artificial lashing, strand pulling machine lashing and three kinds of methods of traditional hoist engine lashing.Artificial lashing: must rely on people's force urges, efficient is low, the lashing limited length; The lashing of tradition hoist engine: connector is made coarse simple and easy, and connection is also insecure, and single traction bundle number is limited, fragile; The strand pulling machine lashing: can only wear a bundle, lashing speed is slow at every turn, and efficient is low.

The utility model content

The technical problem that the utility model will solve is: in order to overcome problems such as traditional strand pulling machine lashing speed is slow, efficient is low, fragile; A kind of steel strand penetrating device is provided; The whole bundle of single hole presstressed reinforcing steel once draws and puts in place, and is easy and simple to handle, can be recycled, and efficient is higher.

The utility model solves the technical scheme that its technical problem adopted: a kind of steel strand penetrating device; It is characterized in that: comprise the butt joint cover; Wire line hitch pressure head, steel strand are withheld head, heading steel strand adapter sleeve and locking thread bush, and the multi beam steel strand put the steel strand overcoat, and the intermediate strand of steel wire bundle is passed heading steel strand adapter sleeve and heading; Heading steel strand adapter sleeve snaps in the butt joint cover; Wire rope snaps in the butt joint cover through the wire line hitch pressure head, the thread bush that locks on the butt joint condom, and the locking thread bush screws on hex nut near wire rope one end; Single bundle steel strand are then withheld head through steel strand and are snapped in the butt joint cover.

The beneficial effect of the utility model is: this steel strand penetrating device connects reliable, and steel strand are connected with the heading mode with drawing element; Force method pushes away to draw generation; The whole bundle of single hole presstressed reinforcing steel once draws and puts in place; Penetrating device is simple to operate, can be recycled; Solved traditional lashing method single lashing scarce capacity, lashing effort, problem such as efficient is low.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further specified.

Like Fig. 1, shown in 2; A kind of steel strand penetrating device comprises butt joint cover 1, and wire line hitch pressure head 2, steel strand withhold 3, heading steel strand adapter sleeve 4 and locking thread bush 5; The multi beam steel strand put steel strand overcoat 6; The intermediate strand of steel wire bundle is passed heading steel strand adapter sleeve 4 and heading, and heading steel strand adapter sleeve 4 snaps in butt joint cover 1, and wire rope snaps in butt joint cover 1 through wire line hitch pressure head 2; Butt joint cover 1 puts locking thread bush 5, and locking thread bush 5 screws on hex nut 7 near wire rope one end; Single bundle steel strand are then withheld 3 through steel strand and are snapped in butt joint cover 1.The step 1 of reeving of the utility model is to six (see figure 1)s:

1. single bundle steel strand (containing simple lay cableties crimp head) pass prefabricated duct earlier;

2. steel strand are withheld head and snap in the butt joint cover;

3. the wire line hitch crimp head is snapped in the butt joint cover;

4. screw on the locking thread bush;

5. screw on hex nut;

6. with the prefabricated duct of steel strand band steel wire penetrating;

Step 7 to ten three (see figure 2)s:

7. the wire rope other end is snapped in the butt joint cover through the wire line hitch crimp head;

8. the intermediate strand of multi beam steel wire bundle is passed heading steel strand adapter sleeve and heading;

9. put the steel strand overcoat;

10. the heading adapter sleeve snaps in the butt joint cover;

11. screw on the locking thread bush;

12. screw on hex nut;

13. pass the precast beam duct with the rope belt steel wire bundle;

Claims

1. a steel strand penetrating device is characterized in that: comprise and dock cover that wire line hitch pressure head, steel strand are withheld head, heading steel strand adapter sleeve and locking thread bush; The multi beam steel strand put the steel strand overcoat; The intermediate strand of steel wire bundle is passed heading steel strand adapter sleeve and heading, and heading steel strand adapter sleeve snaps in the butt joint cover, and wire rope snaps in the butt joint cover through the wire line hitch pressure head; Dock the thread bush that locks on the condom, the locking thread bush screws on hex nut near wire rope one end; Single bundle steel strand are then withheld head through steel strand and are snapped in the butt joint cover.
