Abstract
The invention provides a kind of high-strength prestress rod iron, including barred body, the outer surface of the barred body are provided with some apertures, and the aperture is blind hole or through hole.The beneficial effect of the invention is：Because using above-mentioned technical proposal, in construction, cement can enter in aperture, after theing cement solidifies, increase cement and the bond stress on rod iron surface, enhance product performance.
Description
Technical field
The invention belongs to prestressing steel field, more particularly, to a kind of high-strength prestress rod iron.
Background technology
Prestressing steel first will apply pulling force in construction to steel, and then casting concrete, treats that intensity reaches
To release steel are required, steel is bounced back, offset with the pulling force of normal use load.This requires steel
Bond stress between cement is strong, just can guarantee that in construction or later work, and steel do not bounce back easily,
Ensure the intensity and security of work.
The content of the invention
In view of this, the invention is directed to a kind of high-strength prestress rod iron.
To reach above-mentioned purpose, what the technical scheme of the invention was realized in：
A kind of high-strength prestress rod iron, including barred body, the outer surface of the barred body are provided with some apertures.
Further, the aperture is blind hole or through hole.
Further, the aperture is uniformly distributed.
The invention has the advantages and positive effects of：Due to using above-mentioned technical proposal, constructing
When, cement can enter in aperture, after theing cement solidifies, increase cement and the bond stress on rod iron surface, carry
High product performance.
Brief description of the drawings
In order to illustrate more clearly of the invention embodiment or technical scheme of the prior art, below will
The required accompanying drawing used in embodiment or description of the prior art is briefly described, it should be apparent that,
Drawings in the following description are only the embodiment of the invention, are come for those of ordinary skill in the art
Say, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the invention.
Embodiment
Below in conjunction with the accompanying drawing in the invention embodiment, to the technology in the invention embodiment
Scheme is clearly and completely described, it is clear that described embodiment is only the invention one
Divide embodiment, rather than whole embodiments.It is common based on the embodiment in the invention, this area
The every other embodiment that technical staff is obtained under the premise of creative work is not made, belong to this
The scope of innovation and creation protection, in the case where not conflicting, embodiment and embodiment in the invention
In feature can be mutually combined.
Many details are elaborated in the following description in order to fully understand the invention, still
The invention can also be different from other manner described here to implement using other, art technology
Personnel can do similar popularization in the case of without prejudice to the invention intension, therefore the invention is not
Limited by following public specific embodiment.
Secondly, the invention combination schematic diagram is described in detail, and the invention embodiment is being described in detail
When, for purposes of illustration only, represent that the profile of device structure can disobey general proportion and make partial enlargement, and
And the schematic diagram is example, it should not limit the scope of the invention protection herein.In addition,
The three-dimensional space of length, width and height should be included in actual fabrication.
In the description of the invention, it is to be understood that term " " center ", " longitudinal direction ", " horizontal stroke
To ", " on ", " under ", "front", "rear", "left", "right", " vertical ", " water
It is flat ", " top ", " bottom ", " interior ", the orientation of the instruction such as " outer " or position relationship is based on attached
Orientation or position relationship shown in figure, it is for only for ease of description the invention and is described with simplified, without
Be instruction or imply signified device or element must have specific orientation, with specific azimuth configuration and
Operation, therefore it is not intended that limitation to the invention.In addition, term " first ", " second "
Etc. being only used for describing purpose, and it is not intended that instruction or implying relative importance or implicit indicating meaning
The quantity of the technical characteristic shown.Thus, defining the feature of " first ", " second " etc. can express
Or implicitly include one or more this feature.In the description of the invention, unless otherwise
Illustrate, " multiple " are meant that two or more.
, it is necessary to illustrate in the description of the invention, unless otherwise clearly defined and limited,
Term " installation ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected,
Can also be detachably connected, or be integrally connected；Can be mechanical connection or electrical connection；
Can be joined directly together, can also be indirectly connected by intermediary, can be the company of two element internals
It is logical.For the ordinary skill in the art, above-mentioned term can be understood at this by concrete condition
Concrete meaning in innovation and creation.
As shown in figure 1, the invention is a kind of high-strength prestress rod iron, including barred body 1, it is described
The outer surface of barred body 1 is provided with some equally distributed apertures 2.The aperture 2 is blind hole or through hole.
In construction, cement can enter in aperture, after theing cement solidifies, increase cement and rod iron surface
Bond stress, enhance product performance.
The embodiment of the invention is described in detail above, but the content is only present invention wound
The preferred embodiment made, it is impossible to be considered as the practical range for limiting the invention.It is all according to the present invention
Create the equivalent change made of application range and improve etc., the patent that all should still belong to the invention is contained
Within the scope of lid.
