Abstract
The utility model relates to a sleeper anchor device which relates to the technical field of building elements. The utility model comprises a prestressing tendon and anchor plates which are installed outside both ends of the prestressing tendon, wherein, one end of the prestressing tendon is connected with a nut through screw threads. The utility model is used for reinforcing the intensity of the prefabricated member of the sleeper, and compared with the prior art, the utility model has the advantages of small retracted quantity and simple and convenient tensioning construction after the prestressing tendon is tensioned; in addition, the manufacturing cost of the utility model is reduced by one third than the prior art.
Description
Technical field
The utility model relates to the building unit technical field, especially a kind of device that is used to strengthen the track plate prefabrication member.
Background technology
The rail of the original railroad track of China is erected on the sleeper mostly, and new system high speed light railway is that rail is erected on the prefabricated track plate at present.This track plate will be installed the presstressed reinforcing steel of 3～5 meters length within it, and requires to bounce back less than 3 millimeters behind the tension of prestressed tendon.Existing anchor device to these type of prefabricated units is that an end is the extrusion structure anchor, and the other end is the clamping piece structure anchor.The amount of recovery of the anchor device of this structure in conventional job practices is 5 millimeters, and when stretching construction, adopt the roof pressure technology can dwindle the pyknosis value, but owing to when actual pre-track plate stretch-draw, do not adopt sensor to detect, therefore be difficult to guarantee tension of prestressed tendon after amount of recovery reach technical requirements.In addition, the anchor device manufacturing cost height of this structure.
Summary of the invention
It is easy that subject matter to be solved in the utility model provides a kind of stretching construction, the track plate anchor device of low cost of manufacture.
In order to address the above problem, the scheme that the utility model adopts is: it includes presstressed reinforcing steel and the anchor plate that is contained in outside the presstressed reinforcing steel two ends, and an end of described presstressed reinforcing steel is connected with a nut by screw thread.
The end that above-mentioned presstressed reinforcing steel is connected with described nut is outer can be provided with sleeve pipe, the screw thread of this cover tube outside is connected with described nut, preferably be provided with the impression of groove structure on the surface at presstressed reinforcing steel and described sleeve engages position, perhaps between described presstressed reinforcing steel and described sleeve pipe, be provided with Extruding spring; The above-mentioned prestressed other end can be provided with boss by jumping-up technology.
Above-mentioned Extruding spring is meant a kind of helical spring shape, be used to be contained between presstressed reinforcing steel and its outer sleeve pipe, can embed in presstressed reinforcing steel and the sleeve pipe hard objects of moving to axial of restriction presstressed reinforcing steel and sleeve pipe when sleeve pipe is subjected to mechanical presses to do the time spent.
Owing to adopted such scheme the utility model compared with prior art to have following beneficial effect:
1, the structure that is connected with a nut by screw thread of an end of presstressed reinforcing steel, in the time of can making tension of prestressed tendon, in time screw nut, thereby can effectively prevent the presstressed reinforcing steel retraction, detect just assurance easily without sensor and answer the amount of recovery of muscle to be less than 3 millimeters designing requirement in advance.
2, outside the end that presstressed reinforcing steel is connected with nut, be provided with sleeve pipe, and can solve the difficulty of on the higher presstressed reinforcing steel of hardness, making screw thread by the structure that the screw thread that overlaps the tube outside is connected with described nut.
3, be provided with the impression of groove structure and between presstressed reinforcing steel and described sleeve pipe, be provided with the motion to axial that Extruding spring can limit presstressed reinforcing steel and sleeve pipe reliably on the surface at presstressed reinforcing steel and described sleeve engages position, prevent to answer in advance the retraction of muscle.
5, adopt at a prestressed end and be threaded nut and can reduce manufacturing cost about 1/3rd in the structure that the prestressed other end is provided with boss.
Description of drawings
Fig. 1 is pack into a structural representation in the track plate of an embodiment of the present utility model.
Fig. 2 is the structural representation that the utlity model has nut one end.
Fig. 3 is the surface configuration schematic diagram at presstressed reinforcing steel and sleeve engages position.
The specific embodiment
Below in conjunction with the accompanying drawing example structure of the present utility model is described in further detail:
Among Fig. 1, Fig. 2 and the embodiment shown in Figure 3, this track plate anchor device is contained in the track plate, and it is made up of presstressed reinforcing steel 3, backing plate 1, two anchor plates 2, nut 4 and sleeve pipes 5.Anchor plate 2 is same as the prior art with the syndeton of presstressed reinforcing steel 3, the outer mode by extruding of one end of presstressed reinforcing steel 3 is provided with sleeve pipe 5, the screw thread of the setting of sleeve pipe 5 outsides is connected with nut 4, and the surface of presstressed reinforcing steel 3 and sleeve pipe 5 junctions is provided with the impression of groove structure.The other end of presstressed reinforcing steel 3 adopts the technology of jumping-up to make boss structure, installs backing plate 1 between the boss of presstressed reinforcing steel 3 and anchor plate 2.
