Description
Technical field
The present invention relates to the WELDING STUDS that shear is used for bridge structure and building structure etc., and in particular to a kind of resistance to plucking is not
Shearing resistance WELDING STUDS.
Background technology
Traditional steel-concrete combined structure typically uses WELDING STUDS, makes concrete slab consistent with the deformation of girder steel, reaches
To the purpose of combining structure.The effect of WELDING STUDS is to pass on the shearing and confined concrete plate and steel between concrete slab and girder steel
Beam forms entirety.But such a structure pier top concrete slab is easily ftractureed due to larger hogging moment, apply even in pier top pre-
Stress, because girder steel and concrete have connected into entirety by WELDING STUDS, prestressing force is mainly applied to the steel knot in combining structure
On structure, concrete structure can not effectively carry prestressing force, thus need more steel beams, cause the waste on material.
One of method for solving combination negative moment section of beam concrete slab cracking is to use resistance to plucking not shear stud, makes hogging moment
Area's concrete can longitudinally have small displacement, and so as to be separated with girder steel deformation, concrete slab is no longer complies with plane section with girder steel
It is assumed that now, the internal force that concrete slab is born changes, and moment of flexure greatly reduces, solve splitting for hogging moment area concrete slab
Seam becomes easy, it is possible to reduce the steel using amount of bridge.The material usage of the resistance to plucking used at present not shear stud is more, performance compared with
Difference, working procedure is more, and damage is easily caused in work progress.
The content of the invention
The invention aims to overcome above the shortcomings of the prior art, there is provided and it is a kind of simple and reasonable for structure,
Performance is good and can reduce the resistance to plucking not shearing resistance WELDING STUDS of site operation amount.
The purpose of the present invention is realized by following technical scheme：This resistance to plucking not shearing resistance WELDING STUDS, including ailhead, nail body and
Latex pipe sleeve, the ailhead are fixed on one end of nail body, and the latex pipe sleeve is socketed on nail body, the nail body and latex pipe sleeve it
Between length ratio be 0.8~0.95；The length of the nail body is 5cm~25cm, and the thickness of the latex pipe sleeve is 5mm~9mm.
Preferably, the ailhead and nail body are integrally formed.
Preferably, the Mo Shi hardness of the latex pipe sleeve is 1~1.5, and the rebound degree of the latex pipe sleeve is 100%.
The present invention has the following advantages relative to prior art：
1st, this resistance to plucking not shearing resistance WELDING STUDS to traditional WELDING STUDS by being improved, on the basis of traditional WELDING STUDS
Latex pipe sleeve is additionally arranged, and the length of the nail body of WELDING STUDS is adjusted, and makes length phase of the length of emulsion tube with following closely body
Matching, so that the WELDING STUDS of the present invention has good performance, improve the ability of its resistance to plucking not shearing resistance.
2nd, this resistance to plucking not shearing resistance WELDING STUDS sets up latex pipe sleeve in nail body, changes being monolithically fabricated and applying for traditional WELDING STUDS
Work mode, therefore easily promoted in engineering, the worry that the construction quality of no in-site installation nut cannot be guaranteed, reduces scene and applies
Work workload.
3rd, in this resistance to plucking not shearing resistance WELDING STUDS latex pipe sleeve stable performance, have enough pliability and intensity, pour mixed
It will not be destroyed during solidifying soil, performance reliability is strong.

Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Embodiment 1
As shown in figure 1, the resistance to plucking not shearing resistance WELDING STUDS of the present embodiment, including ailhead, nail body and latex pipe sleeve, the ailhead
One end of nail body is fixed on, the latex pipe sleeve is socketed on nail body, and the length ratio between the nail body and latex pipe sleeve is 0.85；
The length of the nail body is 15cm, and the thickness of the latex pipe sleeve is 7mm.The ailhead and nail body are integrally formed.Make entirely to cut
The firm stable of power nail is high.The Mo Shi hardness of the latex pipe sleeve is 1.2, and the rebound degree of the latex pipe sleeve is 100%.
Shearing resistance nail need not change the ailhead of WELDING STUDS and follow closely the script structure of body this resistance to plucking, and breast is additionally arranged in nail body
Glue pipe socket, i.e., body and concrete slab will be followed closely by latex pipe sleeve and will be separated, so that nail body is only subjected to pulling force, and suffered moment of flexure
Greatly reducing, life-load stress width also greatly reduces, so as to improve the fatigue behaviour of whole WELDING STUDS, Du Genggao safe to use,
Service life is longer.
When the resistance to plucking not shearing resistance WELDING STUDS connection concrete slab and steel plate using the present embodiment, due to ailhead and concrete
Collective effect, concrete slab vertically closely fitting with steel plate, realizing " resistance to plucking ".And the nail body of WELDING STUDS is with mixing
Isolated between solidifying soil by latex pipe sleeve, emulsion tube set has certain thickness, and the modulus of elasticity of latex pipe sleeve is far below mixed
The modulus of elasticity of soil and the modulus of elasticity of steel are coagulated, then is following closely body between concrete equivalent to the gap together with having, this gap
Size it is equal with the thickness of latex pipe sleeve.Therefore when concrete deforms, latex pipe sleeve also accordingly deforms, so as to
The vertically and horizontally deformation of concrete is not prevented, realizes " not shearing resistance " effect, to ensure the stability between concrete slab and steel plate.
The work progress that concrete slab and steel plate are connected using the resistance to plucking not shearing resistance WELDING STUDS of the present embodiment is as described below：
