Abstract
The utility model provides a heavily stressed anticorrosion prestress wire, restraint including central steel strand wires, the steel strand wires overcoat, the spherical column body that the steel strand wires overcoat was formed by connecting for ellipse circular spherical the same shape of a plurality of body in order, its center open have with the same through -hole of diameter is restrainted to steel strand wires, the internal surface of steel strand wires overcoat is equipped with the internal thread structure, it is equipped with spiral reinforcement to inlay in the internal thread framework. The utility model has the advantages of carrying out in anticorrosive, improved the holistic compressive strength of prestress wire book, have high prestressing force, anti -corrosion performance strong, with concrete bond stress reinforcing, longe -lived.
Description
Technical field
The utility model belongs to steel strand technology neck field, especially relates to a kind of high stress protection against corrosion prestress wire.
Background technology
Prestress wire itself owing to being directly twisted into does not have antiseptic property, this prestress wire is very easily corroded and gets rusty, affect use properties, so, in order to prevent corrosion, before installing and using, prestress wire can only add cover one layer of plastics or rubber sleeve pipe, or the surface spray last layer antifouling paint at steel strand. Like this, although the protection against corrosion rustless property of short period of time can be had, but, owing to effectively prestress wire cannot be carried out surface treatment, causing the poor adhesive force of preservative coat, prestress wire still has the anxiety of rust corrosion, and preservative effect is not good, and, the rotproofing before installation also makes using and extremely bothers.
Practical novel content
In view of this, the utility model is intended to propose a kind of high stress protection against corrosion prestress wire, to solve prior art Problems existing.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of high stress protection against corrosion prestress wire, comprise central steel strand bundle, steel strand overcoat, described steel strand overcoat is by the sequently connected spherical column body of the oval-shaped ball of some same shapes, its center has the through hole identical with described steel wire bundle diameter, the internal surface of described steel strand overcoat is provided with female thread structure, is embedded with spiral reinforcing bar in described internal thread framework.
Preferably, described steel strand overcoat is made up of polytetrafluoroethylmaterial material.
Preferably, described spiral reinforcing bar suppresses by prestress wire.
Preferred, the two ends of described prestress wire are provided with sealing termination.
Relative to prior art, high stress protection against corrosion prestress wire described in the utility model has following advantage:
The utility model has is carrying out rot-resistant simultaneously, it is to increase the ultimate compression strength of prestress wire book entirety, has that high pre-stress, Corrosion Protection be relatively strong and the advantage such as the enhancing of concrete bond stress, life-span length.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide of the present utility model it is further understood that schematic description and description of the present utility model is for explaining the utility model, does not form improper restriction of the present utility model. In the accompanying drawings:
Fig. 1 is the structural representation of the prestress wire described in the utility model embodiment.
Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
In description of the present utility model, it will be appreciated that, term " " center ", " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", it is based on orientation shown in the drawings or position relation that the orientation of the instruction such as " outward " or position are closed, it is only the utility model and simplified characterization for convenience of description, instead of indicate or imply that the device referred to or element must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted as restriction of the present utility model. in addition, term " first ", " the 2nd " etc. are only for describing object, and can not be interpreted as instruction or hint relative importance or imply the quantity indicating indicated technology feature. thus, the feature being limited with " first ", " the 2nd " etc. can be expressed or implicit comprise one or more these features. in description of the present utility model, unless otherwise explanation, the implication of " multiple " is two or more.
In description of the present utility model, it is necessary to explanation, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, such as, it is possible to be fixedly connected with, it is also possible to be removably connect, or connect integratedly; Can be mechanically connected, it is also possible to be electrical connection; Can be directly be connected, it is also possible to be indirectly connected by intermediary, it is possible to be the connection of two element internals. For the ordinary skill in the art, it is possible to understand the concrete implication of above-mentioned term in the utility model by particular case.
Below with reference to the accompanying drawings and come the utility model is described in detail in conjunction with the embodiments.
A kind of high stress protection against corrosion prestress wire, as shown in Figure 1, comprise central steel strand bundle 1, steel strand overcoat 2, described steel strand overcoat 2 is by the sequently connected spherical column body of the oval-shaped ball of some same shapes, its center has the through hole identical with described steel wire bundle diameter, and the internal surface of described steel strand overcoat is provided with female thread structure, is embedded with spiral reinforcing bar 3 in described internal thread framework.
Wherein, described steel strand overcoat 2 is made up of polytetrafluoroethylmaterial material; Described spiral reinforcing bar 3 suppresses by prestress wire.
Preferably, the two ends of described prestress wire are provided with sealing termination.
The foregoing is only better embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
