Abstract
The utility model relates to a steel strands bounder which relates to a clamping tool used for drawing steel strands in the construction of prestressing post-tensioning of reinforced concrete of construction bridge. The utility model is provided with a taper body and a taper sleeve, spaces arranged between the taper body and the taper sleeve, fastening locking mechanisms of the taper body and the taper sleeve, and pull rings, wherein, the spaces are used for putting steel strands. The utility model has the advantages of simple manufacture, convenient installation, convenient use, and high efficiency of construction. The placement of the steel strands is firm and reliable, and the clamping force is larger after locking. The steel strands not only can be manually pulled or pulled by a winch but also can be pulled slowly by machines, such as a winding engine and a tractor.
Description
The utility model relates to the special-purpose utensil technical field of building bridge.
Give in the stress construction at bridge, adopt XM molded lines or OXM type to give stress tension anchoring system (post stretching), give stress rib and adopt 7 φ, 5 steel strand, the metal bellows pore-forming when steel strand penetrate the duct, generally adopts metal net method.Net is 7 * 18 of specifications, and the finer wire of external diameter φ 3.2mm (24 strands) is worked out, and about the long 1.5m of net, the metallic traction head of the long 150mm of a φ 45mm is arranged at the top.Entangle steel strand with net, with pull rope artificial or strand grain net steel strand are slowly advanced again.In long duct, because steel strand are heavier, add the friction in steel strand and duct, net can not lead solidly with steel strand and strain, and often pulls to cause the lashing failure, influences construction quality and efficient.
The purpose of this utility model provides a kind of steel strand lashing device, its steel strand firm position, reliable, locking back clamping force is big, manufacturing process is simple, easy to install, efficiency of construction is high.
The utility model is achieved in that a kind of steel strand lashing device, it is characterized in that having cone, and the outside of cone is provided with tapered sleeve, is provided with between cone and tapered sleeve and puts the steel strand space, and be provided with cone and fastening retaining mechanism of tapered sleeve and draw ring.
Above-mentioned cone can be pyramid or terrace with edge, and the tapered sleeve shape is corresponding with it, and preferably cone is cone or garden stage body, and tapered sleeve is that garden tapered sleeve or inside are garden platform shape cover, and preferably its tapering is identical, even stressed the compressing of steel strand during with assurance locking.
Above-mentioned fastening retaining mechanism is: the tapered sleeve top is provided with the hole, and the screw rod of cone end passes this hole, and screw rod is provided with nut.Also can be: the tapered sleeve top be arranged with screwed hole, and cone segments is established the leading screw of rotatable tension, passes this screwed hole, and leading screw is provided with and screws the hole, and this hole also can be made draw ring and use.
Above-mentioned draw ring also can set up, and also the hole of available screw head replaces.Be anti-slip, also can on the conical surface of cone or tapered sleeve, be provided with the ripple that increases friction.
For light and guaranteed strength, above-mentioned cone, the most handy structural alloy steel of tapered sleeve are made, and through heat-treatment quenching, to guarantee case hardness.
For the ease of steel strand are installed, can add a collar, shape of cross section is corresponding with tapered sleeve.
In order to make accurately location and stressed even of steel strand, can be drilled with the steel strand hole on the conical surface of cone or on the inner surface of tapered sleeve, its axis can be parallel with cone or tapered sleeve bus.The hole can be more than 3, garden Zhou Junbu.
The utility model has the advantages that: after the locking, clamping force is big, steel strand firm position, reliable, and easy to install, manufacturing process is simple, construction quality and efficient height.Available artificial or strand grain, yet available machinery as slowly pulling such as hoist engine, tractor, phenomenon do not occur pulling.
Be described further below in conjunction with embodiment and accompanying drawing, but not as to qualification of the present utility model.
Fig. 1 is its structural representation.
Among Fig. 1, cone 1 end is connected with screw rod 3, passes in the hole at tapered sleeve 2 tops, and screw rod is provided with locking nut 4 and draw ring hole 5, and it is the collar that the garden week of cone 1 is provided with 7 steel strand holes 6,7, and 8 is steel strand.
