In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Referring to figure 2., Fig. 2 is a kind of structural schematic diagram of FRP reinforced column provided in an embodiment of the present invention.
The FRP reinforced column, including cylinder 1, it is set to the first FRP band 2 of 1 outer surface of cylinder and the 2nd FRP band
3, the first FRP band 2 and 3 cross-helicity of the 2nd FRP band are wound.
It should be noted that the FRP reinforced column in the present embodiment is intersected using two FRP bands in 1 perficial helical of cylinder
Formed after winding (that is, the first FRP band 2 and the 2nd FRP band 3 are surround in 1 perficial helical of cylinder, the first FRP band 2
Intersect while around cylinder 1 with the 2nd FRP band 3), by the first FRP articles by the way of spiral cross winding
With 2 and the 2nd FRP band 3 be set to the surface of cylinder 1, on the basis of guaranteeing fastening strength, realize that intensity and ductility are promoted
The adjustment of degree, and difficulty of construction reduces, compared with the existing technology in full packet reinforcement means, the present embodiment reduces material
It uses, cost can be reduced accordingly.
Specifically, before the first FRP band 2 and the 2nd FRP band 3 are set to the outer surface of cylinder 1, first to cylinder
1 surface is polished and is cleaned, and after 1 dry tack free of cylinder, carries out positioning from top to bottom or from bottom to top along 1 circumferential direction of cylinder and draws
Line is pasted onto cylinder 1 using binder in the multistage FRP band that will be cut in advance to determine the constraint of FRP band
On each constraint in, along first direction spiral surrounding each section of FRP band formed the first FRP band 2, in a second direction
Each section of FRP band of spiral surrounding forms the 2nd FRP band 3, and after pasting, and can also make to be pasted with the first FRP articles
With 2 and the 2nd FRP band 3 cylinder 1 conserved in dry environment paste preset time (such as 7 days or seven days or more, specifically may be used
To be determined according to the actual situation.
Wherein, after the first FRP band 2 and the 2nd FRP band 3 are pasted onto the corresponding constraint on 1 surface of cylinder, also
Can in 3 outside product plastic covering film of the first FRP band 2 and the 2nd FRP band, 1 surface of FRP band and cylinder to be bonded
Following plastic film after binder solidification, to complete to reinforce the FRP of cylinder 1.
Further, each crosspoint that the first FRP band 2 and second strip are formed after intersecting is along 1 axis direction of cylinder
Equidistantly distributed.
Specifically, the first FRP band 2 and the 2nd FRP band 3 in the present embodiment formed after spiral cross winding it is multiple
Crosspoint, positioned at each crosspoint of same row along the axis direction equidistantly distributed of cylinder 1, wherein 2 He of the first FRP band
The width of 2nd FRP band 3 can be equal, the interval between the specific width value and two neighboring crosspoint of FRP band
To be determined according to the actual situation, the application does not do particular determination.
Further, the spiral angular region of the first FRP band 2 and/or the spiral angular region of the 2nd FRP band 3 are 5 °
~20 °.
Specifically, since the intensity of the increase FRP band with helical angle can reduce, and with the reduction FRP of helical angle
The ductility of band can weaken, so improving the ductility of FRP band, the present embodiment in order on the basis of ensuring FRP band intensity
In the first FRP band 2 and the range of helical angle of the 2nd FRP band 3 all can be 5 °~20 °.
Specifically, the helical angle of the first FRP band 2 in the present embodiment and the helical angle of the 2nd FRP band 3 are equal, and
And the specific value of helical angle can be determined according to the actual situation, the present embodiment does not do particular determination to this.
Further, the cross section of the cylinder 1 in the present embodiment is round, rectangle or ellipse namely the present embodiment
Employed in the first FRP band 2 and the spiral reinforcement means of the 2nd FRP band 3 may be implemented to add various shapes cylinder
It can also be the cylinder that section is rectangle or ellipse Gu being not limited only to cylindrical body, it is, of course, also possible to be the column of other shapes
Body, the present embodiment do not do particular determination.
In addition, the cylinder 1 in the present embodiment can be concrete column, steel column or pin, it can also be steel core concrete column
Deng the present embodiment does not do particular determination to the material of cylinder 1.
It should also be noted that, the present embodiment in the first FRP band 2 and/or the 2nd FRP band 3 be based on carbon fiber,
The band that glass fibre or aramid fiber are made.Certainly, it is not limited only to the FRP item being made using these types of material
Band can also be the FRP band being made using materials such as basalt fibres, can specifically carry out according to the actual situation really
Fixed, the present embodiment does not do particular determination.
The embodiment of the invention provides a kind of FRP reinforced column, including cylinder, it is set to the first FRP band of cartridge outer surface
With the 2nd FRP band, the first FRP band and the winding of the 2nd FRP band cross-helicity.As it can be seen that the first FRP band in the application
The surface of cylinder is set in such a way that cross-helicity is wound with the 2nd FRP band, it can be on the basis for ensureing fastening strength
On, difficulty of construction is reduced, material is saved, reduces cost.
