Detailed description of the invention
Accompanying drawing 1 to 3 is the strenthening member of a kind of impaired armored concrete vertical member, and it includes along impaired reinforced concrete
Soil vertical member 1 short transverse be implanted on impaired armored concrete vertical member 1 multiple drawknot shear reinforcement unit, set
Put the outside of impaired armored concrete vertical member 1 and be connected with drawknot shear reinforcement unit steel reinforcement cage, be cast in and be subject to
Damage outside armored concrete vertical member 1 and for steel reinforcement cage and impaired armored concrete vertical member 1 are formed organic whole
Concrete cover 5.Each drawknot shear reinforcement unit includes that multiple circumference along impaired armored concrete vertical member 1 is divided
The drawknot shear reinforcement 2 of cloth.Steel reinforcement cage includes the multiple rings being distributed along the short transverse of impaired armored concrete vertical member 1
It is connected with multiple hoop stirrups 3 to stirrup 3 and circumferentially distributed multiple vertical along impaired armored concrete vertical member 1
To principal rod 4.
This strenthening member is obtained by following reinforcement means:
Step (1), the surface of impaired armored concrete vertical member 1 is processed, including removing existing structure surface
Floating dust, structure sheaf dabbing process, to form convex-concave surface, in order to well-bonded with the concrete newly poured.
Step (2), along the short transverse of impaired armored concrete vertical member 1 at impaired armored concrete vertical member
Implanting multiple drawknot shear reinforcement unit on 1, each drawknot shear reinforcement unit includes multiple perpendicular along impaired armored concrete
To the circumferentially distributed drawknot shear reinforcement 2 of component 1, multiple drawknot shear reinforcements of the most each drawknot shear reinforcement unit
2 circumferences being generally evenly distributed in impaired armored concrete vertical member 1.
Drawknot shear reinforcement 2 uses surface band rib or the reinforcing bar of screw thread, and drawknot shear reinforcement 2 implant damage reinforcing bar mixes
The degree of depth of solidifying soil vertical member 1 is more than or equal to 10 times of drawknot shear reinforcement 2 diameter, and at drawknot shear reinforcement 2 implant damage
The hole that armored concrete vertical member 1 is formed injects self-compacting concrete so that drawknot shear reinforcement 2 and impaired reinforcing bar
Concrete vertical member 1 is closely worked in coordination with, thus ensures power transmission effect.
Multiple drawknot shear reinforcement unit constitute be positioned at impaired armored concrete vertical member 1 two ends up and down compact part,
Be positioned at the part of rarefaction at the middle part of impaired armored concrete vertical member 1, wherein, adjacent two drawknot shear reinforcement unit of compact part it

200mm；Wherein, the 1/3 of a length of impaired armored concrete vertical member 1 total height of compact part.By at impaired reinforced concrete
Soil vertical member 1 two ends arrange closeer drawknot shear reinforcement unit, it is possible to meet the demand that two ends stress is bigger.
Step (3), arranging steel reinforcement cage in the outside of impaired armored concrete vertical member 1, steel reinforcement cage includes along impaired
Armored concrete vertical member 1 short transverse distribution multiple hoop stirrups 3 be connected with multiple hoop stirrups 3 and along
Circumferentially distributed multiple longitudinal stress muscle 4 of impaired armored concrete vertical member 1.
The number of drawknot shear reinforcement unit is identical with the number of hoop stirrup 3 and one_to_one corresponding is arranged, drawknot shearing resistance steel
Muscle 2 is connected with the hoop stirrup 3 of steel reinforcement cage, and concrete connected mode is: the free end of drawknot shear reinforcement 2 bends about
After 180 ° together with hoop stirrup 3 colligation, and stretch out the length of hoop stirrup 3 after drawknot shear reinforcement 2 colligation not less than vertical
Diameter to principal rod 4.
Step (4), employing template support, casting concrete, concrete curing, make steel reinforcement cage erect with impaired armored concrete
Forming organic whole to component 1, the thickness of the concrete cover 5 that casting concrete is formed is more than or equal to 30mm.Compared to
Hoop concrete strengthening method, the method can effective controlling sections size, sectional dimension increase little, reinforce rear part from
Recuperation to control under conditions of, bearing capacity is obviously improved.
As it has been described above, we are illustrated fully according to objective of the present utility model, but this utility model not limits to
In above-described embodiment and implementation.The scope that the practitioner of correlative technology field can permit at technological thought of the present utility model
Inside carry out different changes and enforcement.
