Abstract
The utility model discloses single tension parts of back cassette jack which is used in anchor construction. The single tension parts comprise a single cross-core jack, a back cassette anchor head, and a location tool-clip; the back cassette anchor head, on which the location tool-clip is installed, is located at the rear part of the jack. In anchor construction, the utility model can solve the ordinary failures in front cassette tension of single strand, ensure construction tempo, and increase the work efficiency of construction members, so as to lower the construction cost of a whole project. The single tension parts have the advantages of simple structure, easy production, convenient installation and dismantling, can availably reduce labor intensity, accelerate the speed of tension and locking, reduce construction cost, and can be widely used as a single anchor tool in tension construction in the construction of foundation pit anchor and anchor cable.
Description
Technical field:
The utility model relates to the civil engineering instrument, particularly anchor pole single tendon stretch used tool in foundation ditch anchor pole, the cable bolting engineering.
Background technology:
At present in the foundation ditch anchor bolt construction; limit by working environment and foundation ditch condition; when stretch-draw; stretch-draw is reserved the steel strand part and is stained with earth and sand grains in the foundation ditch through regular meeting; the removing of earth and sand grains generally is that cassette jack tension equipment carries out stretch-draw before adopting; though cleaning is very clean before the steel strand tension; but can leave some earth; preceding cassette jack is subjected to mechanism to limit frequent the inefficacy after the stretch-draw repeatedly; can't effectively block steel strand and carry out prestressed stretch-draw; not only during charge for loss of working time; waste of manpower; enlarge engineering cost; also be difficult to reach effective stretch-draw purpose, design a kind of easy and simple to handle, time saving and energy saving; the single tendon stretch instrument that the workman grasps easily solves that practical problem has become urgent need in this construction.
The content of utility model:
Overcome the deficiency of existing construction technology, a kind of efficient height, light, with low cost be provided, time saving and energy saving anchor bolt construction with single tendon stretch after cassette jack spare and accessory parts.Anchor bolt construction with single tendon stretch after cassette jack spare and accessory parts it comprise single punching jack, back cassette anchor head and orientation tool intermediate plate, back cassette anchor head is positioned at the jack rear portion, the orientation tool intermediate plate is mounted thereto.Adopt the utility model in construction, in the engineering construction of the more effective solution anchor pole of energy, the situation that cassette stretch-draw was often lost efficacy before the single steel strand guarantees construction speed, raising constructor's operating efficiency, thus reach the purpose that reduces whole engineering construction cost.
Fig. 1 is a front view of the present utility model.
The specific embodiment:
Anchor bolt construction with single tendon stretch after cassette jack spare and accessory parts it comprise single punching jack 1, back cassette anchor head 2 and orientation tool intermediate plate 3, it is mounted thereto that back cassette anchor head 2 is positioned at rear portion, the orientation tool intermediate plate 3 of jack 1.Band degree of the sending center hole of respective steel twisted wire diameter is left in back cassette anchor head 2 centers, adopts height round steel processing and fabricating to form, and it is corresponding to institute use jack rear portion that blank size is wanted, and is convenient to the constructor by tearing open; Orientation tool intermediate plate 3 constitutes, adopts height steel processing and fabricating by three lobes.Effect of the present utility model mainly is a situation of having avoided traditional stretching mode often to lose efficacy, reduce constructor's labour intensity, when stretch-draw, at first the punching jack is passed steel strand, subsequently back cassette anchor head is passed steel strand and place the jack rear portion, install the orientation tool intermediate plate then, jack is made each other co-operation effectively together after pressing, thereby reach purpose in rear portion locking stretch-draw.
Claims (2)
1, a kind of anchor bolt construction with single tendon stretch after cassette jack spare and accessory parts, it comprises jack, it is characterized in that: back cassette anchor head is positioned at the jack rear portion, the orientation tool intermediate plate is mounted thereto.
2, cassette jack spare and accessory parts behind the single tendon stretch as claimed in claim 1, it is characterized in that: the orientation tool intermediate plate is made of three lobes.
