Description
Technical field
It is finished steel strand bundle that the utility model relates to, particularly be a kind of can the finished steel strand bundle of the external hoop of propelling movement type band.
Background technology
To in bridge and railway foundation construction, many steel strand connect in the bellows duct prepared by needs, for overcoming the defect connecting single steel strand existence in bellows duct successively, change into first by many steel strand combing bunchys, the more steel strand being carded to whole bundle are connected in bellows duct.The construction technology that the steel strand of above-mentioned whole bundle are drawn in bellows duct is: first a pull rope is passed duct, then pull rope one end is fixed on the drawing head of steel wire bundle, the other end is fixed on tractor, last under the traction of tractor, pull rope passes through bellows duct with steel wire bundle.
The drawing head of above-mentioned prior art is stressed comparatively large in distraction procedure, and therefore, drawing head is all that the metal selecting intensity high is made, requisite suspension ring or the draw hook that will be provided with the tight pull rope of bolt on described drawing head, the therefore complex structure of drawing head; In addition, drawing head firmly must connect steel strand integral bundle, once connect lax, also there is drawing head with steel strand integral bundle throws off defect in distraction procedure, delay construction speed.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of being suitable for push steel wire bundle through bellows duct technique, have structure simple, cost is low, and fast a kind of of construction safety progress can the finished steel strand bundle of the external hoop of propelling movement type band.
The technical scheme solved the problems of the technologies described above is: a kind of can the finished steel strand bundle of the external hoop of propelling movement type band, described finished steel strand bundle comprises: many steel strand; Through the mark plate of many steel strand; Tie up the steel wire of many steel strand; Hoop, is provided with one in the front end of described many steel strand and connects head, described in connect and fastening be wrapped on the front end of many steel strand; Described hoop banding many steel strand fore-ends outer rim on.
Preferred version is: described in connect head termination, side top face profiles be sphere or the conical surface one of them.
Preferred version is: described in connect head termination, side top face profiles be sphere or the conical surface one of them; Another side connecting head has blind hole, fastening parcel many steel strand front ends in this blind hole.
Preferred version is: described in connect head be working of plastics, fastening parcel many steel strand front ends after making to connect a thermoplastic by hot-working.
The beneficial effects of the utility model are as follows:
1. the utility model overcomes the defect of prior art, and the utility model adopts hoop to make finished steel strand bundle front end
Banding is integrated; The profile of drawing head of the present utility model can pass through bellows duct; Be more applicable for the pusher form of construction work of finished steel strand bundle, and structure is simple, cost reduces by more than 50 than traditional anchor tip.
2, the head that connects of the present utility model only need use high temperature hot melt, and can shrink voluntarily and be adjacent to finished steel strand bundle, operation is simple and convenient, cuts down finished cost.
3, many steel strand front ends of the utility model front end are fixed primarily of hoop, because hoop Material Strength is higher, avoid and connect stressed breaking, add the reliability in finished steel strand bundle propelling movement process.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model provide a kind of can the finished steel strand bundle of the external hoop of propelling movement type band, described finished steel strand bundle 7 comprises: many steel strand 3; Through many steel strand 3 front mark plate 4 and rear mark plate 1; Tie up the steel wire 2 of many steel strand 3; Hoop 5.
Be provided with one in the front end of described many steel strand 3 and connect 6, described in connect on a 6 fastening front end being wrapped in many steel strand 3; Described hoop 5 banding many steel strand 3 fore-end outer rim on.
Described termination, a side top face profiles connecting 6 be sphere or the conical surface one of them.
Described termination, a side top face profiles connecting 6 be sphere or the conical surface one of them; Another side connecting 6 has blind hole, fastening parcel many steel strand 3 front end in this blind hole.
Describedly connect 6 for working of plastics, make to connect fastening parcel many steel strand 3 front end after 6 thermoplastic by hot-working.
In particular, the utility model adapts to pusher to push the product of technique conveying finished steel strand bundle 7 through bellows duct, and above-mentioned pusher pushes technique connecting of finished steel strand bundle 7 in construction 6 not to be needed to bear pulling force.
Of the present utility modelly connect 6 and be arranged on steel wire bundle 7 front end, the front end of many steel strand 3 inserts and connects in 6 another side blind holes, and after high temperature hot melt, plastics connect 6 and shrink rapidly, are tightly wrapped on many steel strand 3 front end.
Mark plate of the present utility model has two, and being each passed through many steel strand 3, is that front mark plate 4 is arranged on many steel strand 3 front end; Another is that rear mark plate 1 is arranged on many steel strand 3 rear end.The arrangement position of each root steel strand 3 in finished steel strand bundle 7 is distinguished in the effect of front mark plate 4 and rear mark plate 1, is convenient to follow-up correspondence and installs ground tackle to each root steel strand 3 Shi Hanzhang.
Many steel strand 3 between front mark plate 4 and rear mark plate 1 are arranged at intervals with many steel wires 2, and steel wire 2 is fixed as one for being tied up by many steel strand 3, prevents finished steel strand bundle 7 steel wire bundle loose.
In finished steel strand bundle 7 front end, many steel strand 3 termination point casings, in hoop 5, are greater than the external diameter of finished steel strand bundle 7 when the hole size of hoop 5 starts, so that many steel strand 3 penetrate.Hoop 5 adopts metal material or other plasticity high strength material.Under the effect of clamping equipment, hoop 5 inwardly extrudes, and plastic strain occurs, is tightly wrapped in many steel strand 3 outer rim, many steel strand 3 is not occurred loose.
As shown in Figure 2, connecting a 6 heating front end top face profiles is sphere, and its internal diameter is greater than the external diameter of finished steel strand bundle 7, so that finished steel strand bundle 7 penetrates smoothly.By many steel strand 3 termination point casing connecting in 6 hole, connect head and can adopt grog or the good material of other thermoplasticity.Under the effect of high temperature, connect 6 to shrink rapidly, tightly be wrapped in many steel strand 3 termination, the slickness of finished product steel wire bundle 7 front end is realized with this, be convenient to whole bundle finished steel strand bundle 7 pushed forward, and prevent due to many steel strand 3 termination and building foundation scratch cause become the loose problem of flat steel wire bundle.
As shown in Figure 1, in use, finished steel strand bundle 7 is arranged on the conveyer belt of pusher, connect a bellows duct (not shown) that 6 alignings are prefabricated, the finished steel strand bundle 7 overall by pusher conveying moves through duct in bellows duct, completes the task of conveying finished steel strand bundle 7.
