Abstract
The utility model provides a stretch -draw anchor of combination formula, fragile anchor dish can be changed, material saving at any time to the device's tentioning head and the separation of anchor dish. Including tentioning head, anchor dish and locating plate, the one end head periphery of tentioning head is equipped with the annular that is used for block anchor dish and turns over the edge, the anchor dish is the loop configuration, turns over along block complex recess with the annular along being equipped with in it. Be equipped with the helicitic texture on the other one end surface of tentioning head, the locating plate is the ring structure, is equipped with the helicitic texture in it on the pore wall, with the tentioning head is equipped with the one end screw -thread fit of helicitic texture. The anchor dish easily decreases, and consequently the anchor dish of damage can be changed at any time to separation design, and without overall change stretch -draw anchor, save material.
Description
Technical field
The utility model relates to electric power conveying technology field, is specifically related to a kind of knockdown concurrent stretching and anchoring device.
Background technology
Along with the fast development of China's power industry, to the bearing capacity of concurrent and life requirement also more and more higher, particularly prestressed concrete electric pole, the low and long service life of its price, market demand amount is large.But the prestressed concrete electric pole that bearing capacity is larger, its stretching force born is also larger, and this just has higher requirement to the processing of prestressed concrete electric pole.In the process of manufacture of prestressed concrete electric pole, stretch-draw is critical process, and it directly has influence on the product quality of electric pole.
Deformed bar fixture and the tensioning head of conventional stretching and anchoring device are integral type structure, in Long-Time Service process, because punching block frequency of utilization is high, deformed bar stretching force is large, wear the stressed yielding or local damage in muscle hole, cause vertical muscle cannot anchoring, come off during the stretch-draw of longitudinal prestressing muscle, need to change whole stretching and anchoring device, cause great waste.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides the stretching and anchoring device of a kind of combined type (separate type), and the tensioning head of this device is separated with anchor disc, can change flimsy anchor disc at any time, saves material.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of combined type stretching and anchoring device, comprises tensioning head, anchor disc and location-plate, and the peripheral annular be provided with for block anchor disc of an end head of described tensioning head turns edge; Described anchor disc is loop configuration, along the groove being provided with the block that to turn edge with annular and coordinating in it.
Other one end outer surface of described tensioning head is provided with helicitic texture, and described location-plate is circular ring structure, and its inner hole wall is provided with helicitic texture, and the threaded one end being provided with helicitic texture with described tensioning head coordinates.
As preferably, tensioning head is hollow structure, and the mesopore of tensioning head is for placing tension rod, and the one end near helicitic texture in mesopore is provided with the projection being used for fixing tension rod, and described bulge clearance is arranged.
As preferably, described anchor disc outer is circumferentially arranged at intervals with wears muscle hole for what be connected and fixed reinforcing bar.
The beneficial effects of the utility model are:
1, anchor disc rapid wear, therefore separate design can change the anchor disc of damage at any time, and without integral replacing stretching and anchoring device, saves material.
2, location-plate coordinates with the threaded one end of tensioning head, is stuck in outside punching block, effectively can stablize the stretching force suffered by deformed bar, and does not need the stretching presstressed reinforcing steel that stretching machine continues.
Be provided with the projection coordinated with tension rod block in the mesopore of 3, tensioning head, bulge clearance arranges and tensioning head can be enable easily to put into and taking-up.

Shown in figure: 1. tensioning head, 2. anchor disc, 3. location-plate, 101. mesopores, 102. is protruding, and 103. annulars turn edge, 201. grooves, and 202. wear muscle hole.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Fig. 2 Fig. 3 Fig. 4, a kind of combined type stretching and anchoring device, comprises tensioning head 1, anchor disc 2 and location-plate 3, and the peripheral annular be provided with for block anchor disc 2 of an end head of tensioning head 1 turns edge 103; Anchor disc 2 is loop configuration, along the groove 201 being provided with 103 blocks that to turn edge with annular and coordinating in it.Other one end outer surface of tensioning head 1 is provided with helicitic texture, and location-plate 3 is circular ring structure, and its inner hole wall is provided with helicitic texture, and the threaded one end being provided with helicitic texture with described tensioning head coordinates.
Tensioning head 1 is hollow structure, and the mesopore 101 of tensioning head is for placing tension rod, and be provided with near one end of helicitic texture in mesopore 101 and be used for fixing multiple protruding 102 of tension rod, described bulge clearance is arranged.Anchor disc 2 outer is circumferentially arranged at intervals with wears muscle hole 202 for what be connected and fixed reinforcing bar.
In use, anchor disc 2 is overlapped with on tensioning head 1, to be turned edge 103 and groove 201 by annular, and anchor disc and tensioning head block coordinate, then deformed bar is penetrated in muscle hole 202, the tension rod of stretching machine stretches in tensioning head mesopore 101, and coordinates in protruding block, draws tensioning head by stretching machine, tension deformed bar, when prestressing force reaches predetermined stretch-draw value, screw location-plate, be fixed on punching block termination.Then unscrew location-plate when the demoulding of electric pole blanks and moulding and conserving, tensioning head and anchor disc are got loose.
The part do not set forth in description is prior art or common practise.The present embodiment only for illustration of this utility model, and is not used in restriction scope of the present utility model, and the amendment such as the equivalent replacement that those skilled in the art make for the utility model is all thought to fall in this utility model right claim institute protection domain.
