Wherein, in Fig. 1:
Supporting construction 1, the first shear resisting board 2, the second shear resisting board 3, through hole 4, arc bent plate 5.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Refer to the overall structure schematic diagram that Fig. 1, Fig. 1 are a kind of detailed description of the invention provided by the present invention.
In a kind of detailed description of the invention provided by the present invention, the shearing resistance combinative structure of bridge mainly includes supporting construction
1 and shear connector.
Wherein, supporting construction 1 is generally used for carrying the Main Load of bridge, such as shearing force etc..About supporting construction 1
A kind of preferred implementation in, this supporting construction 1 can be corrugated steel web structure.It is arranged such, the shearing resistance of supporting construction 1
Ability is strengthened.Certainly, supporting construction 1 can also be the structure of remaining type, such as H profile steel beam etc..
Shear connector is the core component of the present invention, is a kind of structure that supporting construction 1 shear behavior can be substantially improved, one
As be arranged on the surface of supporting construction 1, can weld with supporting construction 1.The primary structure of shear connector includes the first shear resisting board 2 He
Second shear resisting board 3.Concrete, the first shear resisting board 2 and the second shear resisting board 3 column distribution, and the first shear resisting board 2 and the second shearing resistance
The top of plate 3 interconnects, and the first shear resisting board 2 and the bottom of the second shear resisting board 3 be not attached to, but it is separately positioned on support
On two sides on structure 1 surface.So, the first shear resisting board 2 be the formation of with the second shear resisting board 3 the similar triangle of cross section or
Trapezoidal shape.Further, being provided with several through holes 4 on the first shear resisting board 2 and the second shear resisting board 3, this through hole 4 is mainly used
In pouring reinforcement concrete so that the first shear resisting board 2 and the second shear resisting board 3 and the mutual build-in of armored concrete.
So, shearing resistance combinative structure provided by the present invention, by the first shear resisting board 2 and the second shear resisting board in shear connector
3 in triangle or trapezoidal shape, structure shear behavior be greatly improved, simultaneously also by the first shear resisting board 2 and the
Through hole 4 build-in armored concrete set on two shear resisting boards 3, resists the generation due to the uneven stress in the bridge left and right sides
Upwards pull up power, it is possible to effectively prevent the stripping of reinforced concrete floor and steel construction, there is antidumping.Compared to existing
Technology, the present invention, without laying substantial amounts of peg shear connector when construction, can make bridge have enough shear behaviors and resist
Pull out, resistance to capsizing, simultaneously can reduce construction cost when construction, improve efficiency of construction.
About in a kind of preferred implementation of shear connector, the top of its first shear resisting board 2 and the second shear resisting board 3 can lead to
Cross arc bent plate 5 to interconnect.Being arranged such, the top of the first shear resisting board 2 and the second shear resisting board 3 is it can be avoided that stress is concentrated existing
As, arc bent plate 5 can more efficiently build-in armored concrete, make it to resist upwards pull up power, the most dispersed should
Power, improves the first shear resisting board 2 and bearing capacity of the second shear resisting board 3 combinative structure.Certainly, the first shear resisting board 2 and the second shear resisting board 3
The connected mode on top is not limited in arc bent plate, and remaining such as flat board etc. all can use.
Further, if the first shear resisting board 2 being connected with the second shear resisting board 3 by arc bent plate 5 or remaining flat board, then
There will necessarily be between arc bent plate 5 with the first shear resisting board 2 and the second shear resisting board 3 and be connected transition portion, in the present embodiment,
At this transition portion, fillet is set, the fillet etc. between such as 15 °～30 ° so that transition is more smooth, improves shearing further
The anti-load-carrying ability of key, is more not easy deformation.
It addition, on the basis of any of the above-described specific embodiment, can be by set on the first shear resisting board 2 and the second shear resisting board 3
The through hole 4 put is arranged along the equally distributed version in its length direction.Such as, resist at the first shear resisting board 2 and second
On the length direction of shear 3, a through hole 4 can be equidistantly positioned every 100mm.Meanwhile, embedding for convenience of with armored concrete
Gu, also can interconnect arranging position through hole 4 in correspondence with each other on the first shear resisting board 2 and the second shear resisting board 3 so that it is connect into
Integrally.
Further, for convenience of being connected of the first shear resisting board 2 through hole 4 corresponding with on the second shear resisting board 3, also each can be led to
Hole 4 is set to long straight circular hole, or racetrack, i.e. two ends are semi arch, and mid portion is the combinative structure of rectangle.When
So, the shape of each through hole 4 is not limited in long straight circular hole, and remaining such as circular hole, oval groove etc. equally use.
Additionally, for ensureing that shear connector has enough rigidity and intensity while offering each through hole 4, can resist first
The thickness of shear 2 and the second shear resisting board 3 is set to 6～46mm, such as 20,30 or 40mm etc..
Meanwhile, the length of each through hole 4 is also unsuitable long, it is preferable that can account for the first shear resisting board 2 and the second shear resisting board 3
The 30%～60% of width.And the width of each through hole 4, may generally be between 20～160mm, such as 30,70,110,150mm
Deng.
The present embodiment also provides for a kind of bridge, and including crane span structure and the shearing resistance combinative structure being arranged on crane span structure, wherein, this resists
Cutting combinative structure identical with above-mentioned related content, here is omitted.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
Multiple amendment to these embodiments will be apparent from for those skilled in the art, as defined herein
General Principle can realize without departing from the spirit or scope of the present invention in other embodiments.Therefore, the present invention
